Description

A kind of absorption dehumidifying device
Technical field
The utility model relates to the dehumidifying technology of industries such as being suitable for heat energy, chemical industry, metallurgy, electronics, machinery, light industry, relates more specifically to a kind of absorption dehumidifying device.
Background technology
Dehumidifying technology is usually used in processing to obtain dry gas containing humid gas.Except common human settlement's air dewetting, various facility are as the air dewetting in factory floor, warehouse, many industrial departments often need to carry out dehumidification treatments as natural gas and coal gas and various industrial gasses to material gas, energy gas for various purposes.For example, in Chemical Manufacture, need to unstripped gas dehumidifying to-60 DEG C below dew point to prevent that water from dividing the activity that reduces catalyst, in energy industry, compressed natural gas being dehumidified is mainly the formation in order to prevent gas hydrates, in steel and iron industry, need the quality with raising steel products to blast furnace air air dewetting, after the compressed air that the conventional air compression station of the industries such as electronics, machinery is produced must dehumidify, could use.In addition, utilizing dehumidifying technology is in order to collect moisture from contain humid gas to the object of processing containing humid gas sometimes.
Mainly contain at present the industrial dehumidification equipment of three types: freezing type, absorption type, absorption.Freeze drying be by gas cooled to dew point, hydrogenesis is separated out.The advantage of freeze drying is that moisture removal is larger, and shortcoming is that refrigeration plant price is high, power consumption is large, temperature during lower than approximately 15 DEG C dehumidifying effect obviously decline, easily frosting, refrigeration compressor running noise is large.Absorption dehumidifying is to absorb moisture with liquid desiccant as triethylene glycol, lithium chloride solution, and shortcoming is that corrosivity is larger.Adsorption and dehumidification is with the moisture in solid moisture absorbent Adsorption gas.Silica gel is the most frequently used hygroscopic agent, and its hygroscopic capacity can reach 40% of own wt.Other hygroscopic agent has zeolite molecular sieve, activated alumina, calcium chloride, potassium chloride, lithium chloride etc., and its form is generally graininess or is combined in stratiform on base material or backing material etc. by methods such as bonding, sol-gels.Adsorption moisture eliminator is the dehumidification equipment that comprises solid moisture absorbent, the useful load of solid moisture absorbent can be several kilograms to hundreds of kilograms, its citation form has fixed-bed type, moving-bed type, fluidized bed type, revolving bed formula (as desiccant wheel) etc., and its special shape has multistage moving-bed type, multiple stage fluidized-bed formula, double-fluidized-bed formula etc.Before 1900, plant-scale fixed-bed type absorption dehumidifying device is obtaining application aspect air and industrial gasses dehumidifying.About nineteen sixty, revolving bed formula absorption dehumidifying device starts to be applied to the air humidity adjusting of civilian and industrial plants greatly.The advantage of adsorption and dehumidification is that cost of equipment is low, and when temperature is lower, effect on moisture extraction is better, and shortcoming is that the thermal regeneration process energy consumption of hygroscopic agent after saturated is large.
The main difficulty of industrial thermal regeneration hygroscopic agent is:
(1) desorption heat (moisture enters the required heat of gas phase from hygroscopic agent desorption) is greater than evaporation latent heat (heat that liquid evaporation of water is required).For silica gel, desorption heat is approximately 2500 kJ/kg-water.The heat absorption demand that regeneration heating must provide enough heats to meet moisture desorption.
(2) hygroscopic agent is hot non-conductor.For example, the thermal conductivity factor of silica gel is only the thermal conductivity factor that 0.14 W/mK(is equivalent to heat-barrier material asbestos).The heat temperature raising of hygroscopic agent particle is a process comparatively slowly.
(3) hygroscopic agent is micropore class material mostly.For example, the micropore average pore size of silica gel is 20, and Micropore volume reaches 0.6-1 cm 3/ g, internal surface area reaches 600-800 m 2/ g.The moisture of hygroscopic agent absorption is stored up to be stayed in these micropores.When thermal regeneration, these moisture must just can enter gas phase to external diffusion from micropore.Micropore diffusion is a process very slowly, is generally the rate determining step of hygroscopic agent dehydration regenerative process.
(4) regeneration temperature is generally higher than 100 DEG C, and lower than the heat resisting temperature of hygroscopic agent.For example, the regeneration temperature of silica gel is about 100-150 DEG C, and heat resisting temperature is about 200-250 DEG C (regeneration temperature, the heat resisting temperature of different hygroscopic agent products are different).When regeneration heating, to make every effort to even.If hot-spot exceeds heat resisting temperature, will destroy hygroscopic agent structure and cause hydraulic performance decline.
For a long time, the industrial regeneration mode of heating generally adopting is regenerated with hot air method (or being called hot blast method of reproduction, hot gas method of reproduction).For example, the regeneration technology of fixed-bed type air dehumidifier is roughly: the air that is heated to approximately 150 DEG C is passed into dehumidifier and hygroscopic agent bed is heated up gradually reach the regeneration temperature of approximately 100 DEG C, this pre-heating temperature elevation process generally needs 0.5 to 1 hour; Hygroscopic agent bed reaches after regeneration temperature, continue to pass into the hot-air of 150 DEG C to provide moisture desorption required heat, the hot-air of 150 DEG C is cooled to approximately 80 DEG C after hygroscopic agent bed discharges sensible heat, the moisture of hygroscopic agent bed desorption is carried to the external world and is discharged by approximately 80 DEG C of hot-air, and this desorption process generally needs more than 2 hours.The advantage of regenerated with hot air method is that hygroscopic agent bed can obtain heating comparatively uniformly, and shortcoming is must pass into a large amount of hot-airs so that enough heats to be provided, and whole regenerative process continues discharging waste gas, thereby energy resource consumption is larger.

Further, because the working method of above-mentioned absorption dehumidifying device is batch (-type), owing to being only provided with an absorption dehumidifying device and a dehumidifying gas circuit in dehydrating unit, therefore in the time that adsorption moisture eliminator need to carry out thermal regeneration processing, just must be first by valve closing the dehumidify air outlet of blower fan and the gas vent that dehumidified, the gas circuit that makes to dehumidify can not be launched dehumidifying work, could carry out thermal regeneration to adsorption moisture eliminator by regenerative circuit, during thermal regeneration, therefore absorption dehumidifying device can not launch dehumidifying work, therefore, the quantity of described dehumidifying gas circuit is at least two, each dehumidifying gas circuit connection parallel with one another and separating by described some valves, described regenerative circuit is connected respectively the adsorption moisture eliminator in described each dehumidifying gas circuit, gas can circulate and carry out heat exchange individually between any one adsorption moisture eliminator and described regenerative circuit.Object is in the time of a dehumidifying gas circuit job, another dehumidifying gas circuit can temporarily be subject to closing of valve, mutually isolated between dehumidifying gas circuit, be also mutually isolated between adsorption moisture eliminator, therefore, in the time that a dehumidifying gas circuit dehumidifies work, isolated by closing related valve and described regenerative circuit, another dehumidifying gas circuit is connected with regenerative circuit individually by opening related valve, and then carry out thermal regeneration work, in the manner described above, each adsorption moisture eliminator can alternately carry out dehumidifying work and thermal regeneration, make absorption dehumidifying device can carry out uninterruptedly dehumidifying work, have more progressive.
Further, although relate to the alternately switch operating of two adsorption moisture eliminators, the absorption dehumidifying device of the above-mentioned work that can dehumidify continuously is also short of to some extent aspect environmental protection and energy saving, first must recognize, adsorption moisture eliminator carry out dehumidifying work and progressively reach capacity after, its temperature is not high, and follow-up in thermal regeneration process, be to be almost warming up to the temperature of 100 DEG C from normal temperature, each thermal regeneration work all needs a large amount of energy of regenerative heater consumption; On the other hand, the have an appointment temperature of 100 DEG C of adsorption moisture eliminator after having regenerated, normal temperature need to be cooled to and dehumidification operation could be dropped into, prior art is that cold air is passed into the adsorption moisture eliminator after having regenerated in the time of cooling down operation, consequent hot-air is directly to external world's discharge, and the sensible heat of adsorption moisture eliminator is all slatterned; In conjunction with above-mentioned reason, described dehumidifying gas circuit is at least three, between each adsorption moisture eliminator, be also connected with backheat gas circuit, similarly, in actual applications, two adsorption moisture eliminators in backheat gas circuit, circulating fan can be set, impel gas to circulate between two adsorption moisture eliminators by described backheat gas circuit, so that can carry out heat exchange.Therefore, make two connections between adsorption moisture eliminator by backheat gas circuit, can make to carry out heat exchange between two adsorption moisture eliminators, especially will for be just to have completed the adsorption moisture eliminator of thermal regeneration and prepared to carry out the heat exchange between the adsorption moisture eliminator of thermal regeneration, make the high heat of the adsorption moisture eliminator that just completes thermal regeneration pass to the adsorption moisture eliminator of preparing to carry out thermal regeneration, make to prepare to carry out adsorption moisture eliminator first fully preheating before thermal regeneration of thermal regeneration, and a remaining dehumidifying gas circuit is proceeded dehumidifying work, therefore, article three, above dehumidifying gas circuit one after the other switching in the manner described above, therefore, in the situation that ensureing that dehydrating unit can dehumidify work continuously, can also make full use of waste heat, reduce the needed energy of regenerative heater, reduce the regeneration heating energy consumption of dehydrating unit, make device environmental protection and energy saving.
Further, described adsorption moisture eliminator is desiccant wheel, and described dehumidifying gas circuit connects the moisture absorption district of described desiccant wheel, and described regenerative circuit is connected the renewing zone of described desiccant wheel.It should be noted that, in prior art, be made up of hygroscopic material described desiccant wheel inside, desiccant wheel surface point is separated with moisture absorption district, renewing zone, the rotational of described desiccant wheel by movable part drives the hygroscopic material revolution that circulates between regional, and in the use of prior art, the interface of one end, described desiccant wheel moisture absorption district is connected in the air taking port of described dehumidifying blower fan, the gas vent that dehumidified described in the interface of the other end is connected in, has therefore formed dehumidifying gas circuit.Along with the rotation of runner, moisture absorption district part runner proceeds to renewing zone, in regenerative circuit, circulating fan moves continuously, regeneration gas is circulated between regenerative heater and renewing zone, maintain the regeneration temperature of renewing zone, make to proceed to renewing zone absorption the part runner of moisture be first recycled heat temperature raising, then be recycled dehydration regeneration, subsequently, dewatered regeneration part gas along with the rotation of runner comes back to moisture absorption district, the advantage of rotary-type dehydrating unit is to dehumidify continuously and regenerative operation.
Further, in order further to reduce energy consumption, absorption dehumidifying device of the present utility model also can be introduced heat pump of the prior art, and heat pump is the cooling medium liquid circulatory system, and compressor, condenser, expansion valve, evaporimeter etc. are installed in system conventionally.In this programme, described regenerative heater is the condenser being arranged on described heat pump, and therefore, for regenerative circuit, the condenser on heat pump has played the effect of regenerative heater; In addition, the condenser of described regenerative circuit is the first evaporimeter being arranged on heat pump, therefore, for the condensation branch road of dehumidifying gas circuit and regenerative circuit, has played the effect of cooler.
Further, the desiccant wheel of prior art and kind of refrigeration cycle coupling running technology scheme is that evaporimeter is arranged in the dehumidifying gas circuit before the dehumidifying district of desiccant wheel, owing to being normal temperature at the dehumidified gas at this place, therefore the cooling medium liquid temperature in evaporimeter must be lower than approximately 10 DEG C, thereby cause the load of compressor larger, therefore, further, described heat pump is also provided with the second evaporimeter, described the second evaporimeter and the first evaporator series or be connected in parallel, described the second evaporimeter is arranged in dehumidifying gas circuit and at described adsorption moisture eliminator and has dehumidified between gas vent.After the first evaporimeter is connected with the second evaporimeter, all play heat absorption function, and the second evaporimeter is at described adsorption moisture eliminator and dehumidified between gas vent, can in dehumidifying gas circuit, absorb the heat from adsorption moisture eliminator or desiccant wheel, and heat is sent back in heat pump again, because the gas temperature by after adsorption moisture eliminator or desiccant wheel can rise to some extent, gas continues to flow through the second evaporimeter and carries out with it after heat exchange, make the cooling medium liquid temperature can be higher than 10 DEG C, thereby the load of compressor be less.
Further, the outlet side of described the second evaporimeter and the inlet end of described adsorption moisture eliminator are connected, described the second evaporimeter of flowing through except humid gas can be back to adsorption moisture eliminator, can reduce the temperature of adsorption moisture eliminator, effectively improve effect on moisture extraction.
Further, on described regenerative circuit, be provided with for to regenerative circuit replenishment cycles gas or add the air inlet of refrigerating gas.In the time that regenerative circuit needs make-up gas, can open the valve on inflation road, come from treating except humid gas or except a part for humid gas can be supplemented and enter in hydronic regenerative circuit off and on or continuously through described inflation road of extraneous gas or other source of the gas or dehumidifying gas circuit.
Further, on described regenerative circuit, connect and be useful on the exhaust outlet that reduces regenerative circuit air pressure.When dehydrating unit is used for air dewetting, dehumidification operation is generally normal pressure, for energy gas, material gas, when the dehumidification treatments of industrial gasses, dehumidification operation is generally the operation under pressurized conditions, gas of the same race when the gas that is recycled heating when regenerative operation in regenerative circuit is dehumidification operation, pressure when regenerative operation in adsorption moisture eliminator and regenerative circuit may raise, this be because when heating regeneration the gas temperature caused pressure that raises raise, and the water of ADSORPTION STATE is converted into the caused pressure rising of steam, depend on adsorption moisture eliminator, regenerative heater, the pressure rating of the equipment such as circulating fan, adsorption moisture eliminator and/or regenerative circuit possible pressure too high and need decompression, can utilize in this case surge pipe to connect described regenerative circuit with extraneous, on blast pipe, be provided with control valve, opening control valve can discharge unit recyclegas, its adoptable form comprises manually-operated gate, magnetic valve, self-contained pressure regulator or the valve moving according to pressure and/or humidity sensor signal of being controlled by PLC, during to air dewetting, the exhaust outlet of surge pipe leads to atmosphere, or carrying out energy gas, material gas, when industrial gasses dehumidification treatments, the exhaust outlet of surge pipe can lead to reclaimer.

Preferably, described regenerative circuit is made up of two cavitys that are interconnected of described adsorption moisture eliminator inside, in described two cavitys, is provided with hygroscopic agent bed, and described regenerative heater is separately positioned in described two cavitys and avoids described hygroscopic agent bed.
Based on having identical essential features with such scheme, and further expand the applicability of such scheme, the utility model also discloses another kind of absorption dehumidifying device, comprise gas feed to be dehumidified, adsorption moisture eliminator, gas vent has dehumidified, also comprise regenerative circuit, regenerative heater, circulating fan, drainage equipment, and annular gas channel, described adsorption moisture eliminator quantity is several and is serially connected on described annular gas channel, the exhaust end of each adsorption moisture eliminator gas vent that dehumidified described in connecting respectively, the inlet end of each adsorption moisture eliminator connect respectively described in gas feed to be dehumidified, between each adsorption moisture eliminator, be provided with valve, described circulating fan and regenerative heater are arranged on described regenerative circuit, described regenerative circuit is connected respectively input and the output of described each adsorption moisture eliminator, circulating fan orders about gas and flows in regenerative circuit cocycle, described drainage equipment is communicated with regenerative circuit, described drainage equipment comprises exhaust outlet or condenser, described exhaust outlet or condenser connect described regenerative circuit.
Compared with prior art, the utlity model has following beneficial effect:
(1) circulating-heating heats up:
The regenerated with hot air method of prior art has accounted for regenerative heater in the sensible heat loss of pre-heating temperature elevation stage discharging waste gas 40% of heat is provided.In the circulating-heating temperature-rise period of the utility model absorption dehumidifying device, without outside discharging waste gas, avoid exhaust sensible heat loss.In circulating-heating temperature-rise period, unique heat loss is the radiation loss of device outer surface, and in the time that equipment has good insulation, radiation loss is very little.Therefore, the utility model heat that regenerative heater provides in the pre-heating temperature elevation stage has almost all obtained effective utilization.
(2) dehydration cycle regeneration:
The regenerated with hot air method of prior art is generally 60-80 DEG C in the dehydration regeneration stage discharging waste gas temperature having reached after regeneration temperature, and waste gas water capacity is generally below 45g/kg-dry air.That is to say, when every discharge 45g moisture, discharge the 60-80 DEG C of waste gas of 1kg, thermal loss is larger.This is mainly because of the shortage of heat that relies on the sensible heat of air to provide to hygroscopic agent bed so that more moisture desorption.For example, by 25 DEG C, water capacity 15g/kg, the outside air of relative humidity 75% passes into hygroscopic agent bed after being heated to 150 DEG C with regenerative heater, and 150 DEG C of hot-airs discharge after sensible heat is cooled to approximately 80 DEG C and carry from the moisture of hygroscopic agent desorption and discharge to the external world to hygroscopic agent bed.Air is cooled to the sensible heat of 80 DEG C from 150 DEG C and is about 70 kJ/kg-dry air (device outer surface radiation loss account for wherein 2.5%), the desorption heat of moisture is 2500 kJ/kg-water, therefore, under above-mentioned parameter state, the sensible heat that the hot-air of 1 kg discharges to hygroscopic agent bed is only enough to the moisture of desorption 27 g at the most, add the moisture 15g/kg that hot-air contained originally, the water capacity of institute's combustion gas is 42g/kg.Under this parameter state, air has obtained effective utilization from the sensible heat of 150 DEG C to 80 DEG C, and 80 DEG C of following sensible heats of air are wasted to airborne release as used heat, and energy utilization efficiency is only 56%.For a long time, those skilled in the art think and use hot-air after regenerated with hot air hygroscopic agent to carry the moisture of desorption, so must be immediately by the hot-air of approximately 80 DEG C of a large amount of temperature to airborne release, also recognize that heat that in regenerated with hot air method, regenerative heater the provides half of only having an appointment is utilized effectively simultaneously, regeneration energy consumption is large, but the striving direction addressing this problem is in the past confined to sensible heat and the latent heat of how reclaiming exhaust.The utility model is thought: because the moisture from hygroscopic agent desorption that hot-air after regenerated with hot air hygroscopic agent carries is less, so without immediately to airborne release, can make gas circulate between hygroscopic agent and regenerative heater, the heat that regenerative heater is provided passes to hygroscopic agent, only have after recyclegas reaches higher water capacity and just discharged (or condensation), so just reduced discharge amount of exhaust gas and sensible heat loss.For example: first by 25 DEG C, water capacity 15g/kg, the air of relative humidity 75% is heated to 150 DEG C with regenerative heater, water capacity 15g/kg, after relative humidity 2.5%, pass into hygroscopic agent bed, 150 DEG C of hot-airs temperature when carrying desorption moisture after hygroscopic agent bed discharges sensible heat cooling and discharge from adsorption moisture eliminator is 80 DEG C, water capacity 42g/kg, relative humidity 13%; These 80 DEG C of air enter heat-exchanging part again, are heated to 150 DEG C, water capacity 42g/kg, and the rear circulation of relative humidity 7.5% enters adsorption moisture eliminator, and while again discharge from adsorption moisture eliminator, temperature is 80 DEG C, water capacity 69g/kg, relative humidity 20%; So repeatedly circulation, the water capacity in recyclegas raises gradually.When recyclegas reaches 80 DEG C of temperature, water capacity 150g/kg, the state of relative humidity 40% is during to airborne release, when every removal 135g moisture to the hot-air of airborne release 1 kg.Compare with the hot-air that discharges 1 kg in the regenerated with hot air method of prior art when every removal 27 g moisture, the utility model has reduced exhaust sensible heat loss significantly.Adopting another one benefit of the present utility model is that recyclegas contains higher water vapor concentration, and the recycling of its condensation latent heat is comparatively easy.
(3) remove heat of adsorption:
The heat of adsorption producing when dehumidification operation can make the hygroscopic agent bed about 5-10 DEG C that heats up, and has reduced effect on moisture extraction, and especially, in hot and humid situation, adsorption and dehumidification ability may obviously decline.Embodiment 2,7, the 9 removable heats of adsorption that provide in detailed description of the invention, make effect on moisture extraction more stable.
(4) recovery waste heat:
(a) sensible heat of regeneration exhaust (or recyclegas) in the utility model and the recovery of latent heat:
The regeneration exhaust parameter of the regenerated with hot air method of prior art is generally: temperature 60-80 DEG C, below water capacity 45g/kg, dew point is lower than 39 DEG C.Under this parameter state, can only reclaiming exhaust sensible heat with conventional waste heat recovery apparatus approximately 30%, be difficult to recycle latent heat.And heat transfer temperature difference is little, need larger heat exchange area, also infeasible economically.In regenerative circuit of the present utility model, recyclegas is generally in the parameter in adsorption moisture eliminator exit: 80 DEG C of temperature, more than water capacity 150g/kg, dew point is higher than 60 DEG C.Be easier to reclaim the water vapor condensation latent heat of recyclegas with conventional waste heat recovery apparatus.Embodiment 5,6,7,9 of the present utility model has advantages of recyclegas sensible heat and latent heat in reclaiming loop.
(b) recovery of the sensible heat of the hygroscopic agent bed of thermal regeneration after completing:
The have an appointment temperature of 100 DEG C of adsorption moisture eliminator after thermal regeneration completes, need to be cooled to normal temperature and could drop into dehumidification operation.Prior art is that cold air is passed into the adsorption moisture eliminator after having regenerated in the time of cooling down operation, and consequent hot-air is directly to airborne release, and the sensible heat of adsorption moisture eliminator is all slatterned.The sensible heat that embodiment 5,9 of the present utility model is recyclable has just completed adsorption moisture eliminator after the regeneration part runner of regeneration (or just completed) will thermal regeneration for the preheating next one the adsorption moisture eliminator part runner of thermal regeneration (or will), having saved regeneration heating institute calorific requirement.
(c) recovery of the heat of adsorption producing when dehumidification operation:
Heat of adsorption make the to dehumidify temperature rise of γ-ray emission is little, is generally difficult to utilize.In embodiment 6,7,9 of the present utility model, refrigerating/heat pump cycle fluid can reach 20 DEG C, recyclable part heat of adsorption with the temperature difference of removing humid gas.When embodiment 8 needs the low temperature and high relative humidity of heat supply and dehumidifying to be applied to indoor air dehumidification season at the same time, heat of adsorption has improved indoor air temperature, and in fact heat of adsorption is also recovered and has utilized.

embodiment 1
As shown in Figure 1, for being equipped with the batch (-type) dehydrating unit schematic diagram of condenser in a kind of regenerative circuit in the utility model, this dehydrating unit comprises the hygroscopic agent bed 101 being made up of hygroscopic agent particle in adsorption moisture eliminator 1(), gas feed to be dehumidified 10, dehumidify gas vent 11, dehumidifying blower fan 2, circulating fan 3, regenerative heater 6, condenser 7.Gas feed 10 to be dehumidified, dehumidifying blower fan 2, adsorption moisture eliminator 1, the gas vent 11 that dehumidifies connects by pipeline, forms dehumidifying gas circuit.Adsorption moisture eliminator 1, circulating fan 3, regenerative heater 6 are connected by pipeline, form regenerative circuit; The two ends of condenser 7 are connected with regenerative circuit by pipeline, form condensation branch road, the gas flow that is condensed by valve 301,701,702 adjustable throttle through condenser 7, and an operation cycle of this batch (-type) dehydrating unit has comprised dehumidifying, regeneration step:
(A) dehumidifying: open valve 108,109, close other valve, operation dehumidifying blower fan 2, make the gas flow to be dehumidified being entered by import 10 through adsorption moisture eliminator 1, moisture in gas is by hygroscopic agent bed 101 Adsorptions,, except humid gas is through exporting 11 discharges, when hygroscopic agent bed 101 is saturated, carry out next step regenerative operation nearly.
(B) regeneration:
(1) circulating-heating heats up: dehumidifying blower fan 2 out of service, open valve 301,602, close other valve, operation circulating fan 3, gas is circulated between adsorption moisture eliminator 1 and regenerative heater 6, the heat that regenerative heater 6 is provided passes to adsorption moisture eliminator 1, thereby makes hygroscopic agent bed 101 heat up and reach regeneration temperature gradually.
(2) dehydration cycle regeneration: continue operation circulating fan 3, gas is circulated between adsorption moisture eliminator 1 and regenerative heater 6, the heat that regenerative heater 6 is provided passes to adsorption moisture eliminator 1 to maintain the regeneration temperature of hygroscopic agent bed 101.After hygroscopic agent particle in hygroscopic agent bed 101 is heated, granule interior produces higher steam partial pressure, and this steam partial pressure is higher than the steam partial pressure in recyclegas.Under the poor driving of steam partial pressure, in hygroscopic agent particle, moisture is to gas phase diffusion, and the water capacity in recyclegas raises gradually.
(3) discharge moisture: in step (1) or (2) operating period, when the water capacity of recyclegas reaches 60g/kg-dry gas or when above, can start the aperture of control valve 301,701,702, make off and on or continuously the part recyclegas condenser 7 of flowing through, gas institute containing water vapor is condensed, and condensed water is discharged from floss hole 14.Continue the operation of carrying out above-mentioned dehydration cycle regeneration simultaneously and discharging moisture until evaporated condensation water carries out next step cooling down operation after discharging.
(4) cooling: regenerative heater 6 stops heating, opens valve 108,109, closes other valve, operation dehumidifying blower fan 2, passes into cold air to adsorption moisture eliminator 1 and carries out cooling; Or open valve 602,701,702, close other valve, operation circulating fan 3, thus make gas between adsorption moisture eliminator 1 and condenser 7, circulate cooling adsorption moisture eliminator 1.Adsorption moisture eliminator 1 enters the next operation cycle after being cooled to normal temperature.
Dehydrating unit is when the air dewetting, and dehumidification operation is generally normal pressure, and during for the dehumidification treatments of energy gas, material gas, industrial gasses, dehumidification operation is generally the operation under pressurized conditions.Gas of the same race when the gas that is recycled heating when regenerative operation in regenerative circuit is dehumidification operation.Pressure when regenerative operation in adsorption moisture eliminator and regenerative circuit may raise, this be because (a) when heating regeneration the gas temperature caused pressure that raises raise, and (b) water of ADSORPTION STATE is converted into the caused pressure of steam and raises, depend on adsorption moisture eliminator, regenerative heater, the pressure rating of the equipment such as circulating fan, adsorption moisture eliminator and/or regenerative circuit possible pressure too high and need decompression, preferably, Fig. 1 shown device and all detailed description of the invention of the present utility model all can arrange an exhaust outlet 16 for discharge unit recyclegas and/or steam, preferably, can also control valve 8 be set at exhaust outlet 16, the adoptable form of control valve 8 comprises the valve moving according to pressure and/or humidity sensor signal of being controlled by PLC, self-contained pressure regulator, magnetic valve or manually-operated gate, can also omit control valve 8, the exhaust outlet 16 that suitable diameter is only set carrys out recyclegas and/or the steam (now its capacity is controlled by gas pressure in regenerative circuit) of discharge unit.During to air dewetting, exhaust outlet 16 leads to atmosphere; While carrying out energy gas, material gas, industrial gasses dehumidification treatments, exhaust outlet 16 leads to (condensation) reclaimer.
In the above-mentioned circulating-heating temperature rise period, in the time that the temperature of hygroscopic agent bed 101 reaches approximately 60 DEG C, may there is a small amount of moisture to start desorption, but the heat that regenerative heater 6 provides is mainly used in the hygroscopic agent bed 101 required sensible heat that heats up, the mark of circulating-heating temperature rise period is that the temperature of hygroscopic agent bed 101 continues to rise.In the dehydration cycle regeneration stage, the temperature of hygroscopic agent bed 101 is basicly stable in regeneration temperature, the heat that regenerative heater 6 provides is mainly used in the desorption heat of moisture, when air dehumidifier thermal regeneration, circulated air is reproduced after heater 6 heating reach approximately 150 DEG C and passes into adsorption moisture eliminator 1,150 DEG C of hot-airs discharge after sensible heat is cooled to approximately 80 DEG C and discharge from adsorption moisture eliminator 1 to hygroscopic agent bed 101, and then circulation enters regenerative heater 6, and being again heated to 150 DEG C is a circulation.The heat that adds that in each circulation, regenerative heater 6 provides to recyclegas is 70 kJ/kg-dry air, device outer surface radiation loss accounts for this and adds 2.5% of heat, the desorption heat of moisture is 2500 kJ/kg-water, therefore the sensible heat that, in each circulation, the circulated air of per kilogram discharges to hygroscopic agent bed is only enough to the moisture of desorption 27 g.Improve gas temperature to the 150 DEG C above dehydrating amount that can increase each circulation that regenerative heater 6 heats, but the raising of heating-up temperature is subject to the restriction of hygroscopic agent heat resisting temperature.When hygroscopic agent is silica gel, zeolite molecular sieve, activated alumina, the highest gas temperature that regenerative heater 6 heats is respectively approximately 180,400,300 DEG C.
In the above-mentioned dehydration cycle regeneration stage, in the time that the temperature of hygroscopic agent bed 101 reaches approximately 100 DEG C, the steam partial pressure of hygroscopic agent granule interior can reach 1 atmospheric pressure; When the temperature of hygroscopic agent bed 101 is during higher than 100 DEG C, the steam partial pressure of hygroscopic agent granule interior can be greater than 1 atmospheric pressure.The order of magnitude of the steam partial pressure in the recyclegas circulating between adsorption moisture eliminator 1 and regenerative heater 6 is 0.1 atmospheric pressure of 0.01 –.Therefore, a small amount of moisture in recyclegas is very little for the impact of the moisture desorption process of hygroscopic agent particle.In the dehydration cycle regeneration stage, the water capacity in recyclegas can raise gradually.
In the operation of above-mentioned discharge moisture, the part recyclegas condenser 7 of flowing through, gas institute containing water vapor is condensed, and condensed water is discharged from floss hole 14.Recyclegas is condensed and discharges while returning to regenerative circuit after moisture and need to provide heat to reheat intensification by regenerative heater 6, and therefore, the water capacity of the recyclegas being condensed is higher, and energy consumption is lower.General recyclegas reaches the water capacity of 60g/kg-dry gas, preferably, reach 150g/kg-dry gas (80 DEG C of temperature, relative humidity 40%, 60 DEG C of dew points) or above after, just start to discharge moisture and operate.Water capacity is under the parameter state of 150g/kg-dry gas, and the gas flow of the condenser 7 of flowing through is about 20% of recyclegas total flow.
Above-mentioned circulating fan 3 also can adopt axial fan, and this axial fan can be arranged in adsorption moisture eliminator 1.Although prior art generally adopts dehumidifying air flow direction and regeneration air stream to flow to as reverse mode, for the utility model, whether dehumidifying air flow direction and regeneration air stream flow to is reverse unimportant.For all specific embodiments of the present utility model, circulating fan 3 can be selected Double-way axial flow formula blower fan, and when heating regeneration circulating fan 3 alternately rotate and reverse and can make hygroscopic agent bed 101 obtain heating more uniformly.Regenerative heater 6 can adopt any type of firing equipment, such as electric heater, heat exchanger, use gas, liquid or solid fuel heater, utilize the heater of new forms of energy or regenerative resource as solar thermal collector etc.
Single tower batch (-type) dehydrating unit that the present embodiment is described is applicable to the occasion of the discontinuous use dry gas of the industries such as heat energy, chemical industry, metallurgy.
embodiment 2
As shown in Figure 2, be another kind of batchwise adsorption dehydrating unit of the present utility model.
In adsorption moisture eliminator 1, have the hygroscopic agent bed 101,102 that formed by hygroscopic agent particle and with the spaced heat exchanging pipe 105,106 of hygroscopic agent bed 101,102, hygroscopic agent bed 101,102 does not contact to avoid hygroscopic agent bed 101,102 hot-spots with the heat exchange surface of heat exchanging pipe 105,106; Circulating fan 3 is Double-way axial flow formula blower fan; Heat transferring medium is entered by import 12, is discharged by outlet 13.An operation cycle of this device has comprised dehumidifying, regeneration step:
(A) dehumidifying: pass into cooling medium in heat exchanging pipe 105,106, open valve 108,109, close other valve, operation dehumidifying blower fan 2, make the gas flow to be dehumidified being entered by import 10 through adsorption moisture eliminator 1, moisture in gas is by hygroscopic agent bed 101,102 Adsorptions, and gas is cooling by heat exchanging pipe 105,106, except humid gas is through exporting 11 discharges.When hygroscopic agent bed 101,102 is saturated, carry out next step regenerative operation nearly.
(B) regeneration:
(1) circulating-heating heats up: open valve 301,302, close other valve, in heat exchanging pipe 105,106, pass into heat medium, operation circulating fan 3, gas is circulated in regenerative circuit, the heat that heat exchanging pipe 105,106 is provided passes to hygroscopic agent bed 101,102, thereby makes hygroscopic agent bed 101,102 heat up and reach regeneration temperature gradually.
(2) dehydration cycle regeneration: continue operation circulating fan 3, gas is circulated in regenerative circuit, the heat that heat exchanging pipe 105,106 is provided passes to hygroscopic agent bed 101,102 to maintain the regeneration temperature of hygroscopic agent bed 101,102.After hygroscopic agent particle in hygroscopic agent bed 101,102 is heated, moisture is to gas phase diffusion, and the water capacity of recyclegas raises gradually.
(3) discharge moisture: when the water capacity of recyclegas reach 60g/kg-dry gas or above after, open off and on or continuously control valve 8, the recyclegas of discharge unit and/or steam.The operation of proceeding above-mentioned dehydration cycle regeneration and discharge moisture is until the water capacity of recyclegas is carried out next step cooling and drying process after no longer increasing.
(3) cooling and dry: operation dehumidifying blower fan 2, pass into cold air to adsorption moisture eliminator 1 and carry out coolingly, make the part cold air circulating fan 3 of flowing through make it dry simultaneously; Or in heat exchanging pipe 105,106, pass into cooling medium, operation circulating fan 3, cooling hygroscopic agent bed 101,102.Adsorption moisture eliminator 1 enters the next operation cycle after being cooled to normal temperature.
The cooling medium passing in heat exchanging pipe 105,106 when above-mentioned dehumidification operation can be cold water, cold air etc.; The heat medium passing in heat exchanging pipe 105,106 when regenerative operation can be high-temperature steam, hot-air, hot flue gas, any gas or the liquid that has proper temperature of heat conduction wet goods.
The effect that passes into cooling medium in above-mentioned dehumidification operation in heat exchanging pipe 105,106 is to remove heat of adsorption.When gas absorption, the kinetic energy major part of gas molecule motion is converted into heat energy, and therefore, absorption is an exothermic process, and the heat discharging is called heat of adsorption.Due to the generation of heat of adsorption, hygroscopic agent bed and except the temperature rise of humid gas generally can reach 5-10 DEG C (even higher, to depend on the factor such as temperature, humidity, hygroscopic agent performance of gas) when dehumidification operation, temperature rise has reduced effect on moisture extraction to a certain extent.In heat exchanging pipe 105,106, passing into cooling medium removes heat of adsorption and can improve effect on moisture extraction.If 101,102 temperature rises of hygroscopic agent bed are excessive in the time of dehumidification operation, when operation dehumidifying blower fan 2 passes into adsorption moisture eliminator 1 and treats to carry out dehumidification operation except humid gas, open valve 301,302, operation circulating fan 3, make partly to have dehumidified gas backstreaming, can further improve cooling effect.In the time that adsorption moisture eliminator 1 adopts fluidized bed type, hygroscopic agent bed 101,102 can be merged into a fluid bed, heat exchanging pipe 105,106 is directly placed in fluid bed, can increase substantially the heat transfer efficiency between dehumidifying cooling and when heating regeneration heat exchanging pipe 105,106 and hygroscopic agent bed 101,102, and hygroscopic agent particle hygroscopic agent particle in the time of fluidized state contacts and also there will not be hot-spot with heat exchanging pipe 105,106.
In above-mentioned discharge moisture operation, what discharge through control valve 8 is the recyclegas of about 60-80 DEG C temperature and the mixture of steam, and therefore, the water capacity of the recyclegas being discharged from is higher, and the energy consumption of regenerating is lower.The water capacity of general recyclegas reach 60g/kg-dry gas or above after, preferably, reach 150g/kg-dry gas or above after, just start to discharge moisture and operate.After the mixture that discharges recyclegas and steam through control valve 8, the circulating air scale of construction in regenerative circuit reduces gradually, water vapor concentration raises gradually, and steam partial pressure between hygroscopic agent granule interior and recyclegas is poor to be reduced so that the hygroscopic agent regeneration of can not thoroughly dewatering gradually.But in general hygroscopic agent is without thorough regeneration, as long as most of moisture desorption can drop into dehumidification operation.If hygroscopic agent needs thoroughly regeneration, can, in carrying out dehydration cycle regenerative operation, open valve 108, operation dehumidifying blower fan 2, to regenerative circuit replenishment cycles gas.Certainly the device that, embodiment 2 shown devices also can be similar to embodiment 1 arranges like that condensation branch road and discharges moisture.Embodiment 1 shown device adopts condensed water outlet mode, and the Main Function of its control valve 8 is decompressions; Embodiment 2 shown devices adopt the mode of direct vent water vapor to discharge moisture, and the effect of its control valve 8 is mainly vent water vapor.All specific embodiments of the present utility model all can adopt condensed water outlet mode or direct discharging modes to discharge moisture.The advantage of condensed water outlet mode is without setting up air inlet and discharge duct; Directly the advantage of discharging modes is not need to arrange condenser.The control valve 8 for vent water vapor in Fig. 2 shown device and all detailed description of the invention of the present utility model can adopt any type of valve, can also omit control valve 8, the exhaust outlet 16(that suitable diameter is only set now its capacity is controlled by gas pressure in regenerative circuit).In the time adopting direct vent water vapor mode to discharge moisture, should adopt higher regenerative operation temperature, make the minimum temperature place of regenerative circuit there is the temperature higher than 100 DEG C.
The NM part of the present embodiment is similar to Example 1, and its operation principle and application scenario are identical with embodiment 1, repeat no more herein.
embodiment 3
As shown in Figure 3, be another kind of batchwise adsorption dehydrating unit of the present utility model.
In adsorption moisture eliminator 1, there are the hygroscopic agent bed 101,102,103,104 that formed by hygroscopic agent particle and heat exchanging pipe 105, circulating fan 107; Dividing plate 100 is two cavitys by adsorption moisture eliminator 1 interior separation.Operation circulating fan 107 can make gas circulate in adsorption moisture eliminator 1.An operation cycle of this dehydrating unit has also comprised dehumidifying, regeneration step.In the time that needs are discharged moisture, can open valve 701, because the interior gas pressure of adsorption moisture eliminator 1 is higher than condenser 7 internal pressures, the interior gas of adsorption moisture eliminator 1 enters condenser 7, and gas institute containing water vapor is condensed, and condensed water is discharged from floss hole 14.The advantage of the dehydrating unit of built-in heat exchanging pipe and circulating fan is to have saved outside circulating line and valve, has therefore reduced radiation loss.Fig. 3 shown device is only a kind of preferred embodiments, those of ordinary skill in the art easily carries out various variations, for example, change form, quantity and the installation site of form, regenerative heater and circulating fan and the form of dividing plate and the quantity (or cancelling dividing plate) of adsorption moisture eliminator, can gas be circulated between regenerative heater and hygroscopic agent bed by the forced convection of circulating fan, reach similar effect.Within the various variations that can make according to the instruction of the present embodiment are all included in the protection domain of the utility model claim.
The NM part of the present embodiment is similar to Example 2, and its operation principle and application scenario are identical with embodiment 2, repeat no more herein.
embodiment 4
Due in the thermal regeneration process of hygroscopic agent, the microcellular structure of hygroscopic agent itself has determined that the heat and mass of hygroscopic agent inside is very slowly, be generally the rate determining step of its thermal regeneration, the condition of hygroscopic agent outside is as little in recyclegas flow velocity General Influence, therefore, cancel circulating fan and only rely on and with regenerative heater, part recyclegas is heated to free convection that the temperature difference that causes causes gas is circulated between regenerative heater and hygroscopic agent bed is feasible.As shown in Figure 4, be the batchwise adsorption dehydrating unit of a kind of heat transfer free convection mode of the present utility model.In adsorption moisture eliminator 1, there are the hygroscopic agent bed 101,102 and the regenerative heater 105,106 that are formed by hygroscopic agent particle; Dividing plate 100 is left and right two cavitys by adsorption moisture eliminator 1 interior separation.When regeneration heating starts, close all valves, regenerative heater 105,106 alternately heats.When regenerative heater 105 heats, regenerative heater 106 is while stopping heating, density after the gas of right cavity is heated is less than the gas density of left cavity, and therefore, the gas of right cavity moves upward, the gas of left cavity moves downward, and the interior γ-ray emission of adsorption moisture eliminator 1 is circulated.When regenerative heater 105 stops heating, regenerative heater 106 while heating, the opposite direction circulating.When the water capacity of recyclegas reaches 60g/kg-dry gas or when above, can start to discharge moisture operation: open valve 110,701,702 and regulate the gas flow of the condenser 7 of flowing through, regenerative heater 105,106 heats simultaneously, the gas of adsorption moisture eliminator 1 inside moves upward, gas in external pipe flows downward, the part recyclegas condenser 7 of flowing through, the moisture discharge that is condensed.The advantage of the dehydrating unit of heat transfer free convection is homogeneous heating, and radiation loss is little, has omitted after circulating fan cost of equipment and power consumption lower, and during for the dehumidification treatments of energy gas, material gas, industrial gasses, security is higher.Fig. 4 shown device is only a kind of preferred embodiments, those of ordinary skill in the art easily carries out various variations, for example change form, form, quantity and the installation site of regenerative heater and the form of dividing plate and the quantity (or cancelling dividing plate) of adsorption moisture eliminator, can gas be circulated between regenerative heater and hygroscopic agent bed by gas the produced free convection of being heated, reach similar effect.For example, a hygroscopic agent bed and a regenerative heater are only set in adsorption moisture eliminator, this regenerative heater is positioned at the below of hygroscopic agent bed, do not touch with hygroscopic agent bench grafting, when regenerative heater heating, by the free convection of gas, heat is passed to hygroscopic agent bed inside, hygroscopic agent bed is heated and produces steam air pressure is raise, and steam enters the condenser discharge that is condensed.And for example, flat type solar heat collector can be used as regenerative heater and carrys out the recyclegas in thermal regeneration loop, adsorption moisture eliminator is made as rectangle, and be arranged on the one side backlight of flat type solar heat collector, most significant end in solar thermal collector and least significant end respectively with adsorption moisture eliminator in most significant end and least significant end connect, in solar thermal collector, gas is flowed into adsorption moisture eliminator by solar radiation heat temperature raising after moving upward, move downward compared with cold gas in adsorption moisture eliminator and circulate and enter solar thermal collector, thereby realize solar energy heating regeneration adsorption moisture eliminator in the mode of heat transfer free convection.It should be noted that, can not list all embodiments of the present utility model at this, within other any is all included in the protection domain of the utility model claim according to principle of the present utility model and the designed detailed description of the invention of flesh and blood.
