Description

Directly vaporation-type is united dehumidifier

One, technical field

The utility model relates to a kind of dehumidifier, particularly a kind of direct vaporation-type associating dehumidifier.

Two, background technology

Freeze drying environment to the not high condition of humidity requirement under (RH ≯ 60～65%), effect is relatively good, stable performance and energy consumption are also lower, use at present more extensive.But, adopt freeze drying just obviously uneconomical in the occasion of production environment to humidity requirement higher (RH=45 ± 5%).Adopt rotary wheel dehumidifying, will not influenced by air dew point, and moisture removal is big, be specially adapted under the low humidity condition, if but all adopt the rotary wheel dehumidifying of solid-state absorption principle to dehumidify, because its regeneration energy consumption is bigger, this kind scheme is also uneconomical.Utilize the associating dehumidifier of chilled water for refrigerant, low-temperature receiver need additionally be provided and need accessory systems such as water pump, pipeline, it uses inconvenient and neither be most economical.

Three, summary of the invention

1, goal of the invention: the purpose of this utility model provides a kind of direct vaporation-type associating dehumidifier that freeze drying and rotary wheel dehumidifying can be organically combined, this dehumidifier combines that freeze drying is low at dehumidification rate height under the high dew point operating mode, energy consumption, stable performance and rotary wheel dehumidifying are subjected to the double dominant that the dew-point temperature restriction is little and moisture removal is big under low dew point operating mode, has advantage easy for installation simultaneously.

2, technical scheme: for achieving the above object, direct vaporation-type associating dehumidifier described in the utility model is formed by connecting by freeze drying, two refrigeration systems of cooling and processing air, two wind systems of regeneration air.For sake of convenience, following tape label explanation.

Parts and annexation thereof that the freeze drying system comprises are: refrigeration compressor 15 to water-cooled condenser 13 to hand valve 14 to device for drying and filtering 12 to magnetic valve 11 to heating power expansion valve 10 to evaporimeter 9 to refrigeration compressor 15;

Parts and connected mode thereof that cooling system comprises are: refrigeration compressor 16 to water-cooled condenser 18 to hand valve 17 to device for drying and filtering 19 to magnetic valve 20 to heating power expansion valve 21 to evaporimeter 23 to refrigeration compressor 16;

Handling the air wind system is that centrifugal blower 22 makes pending air behind evaporimeter 9 cooling and dehumidifyings, through runner 8 treatment region adsorption and dehumidifications, sends into the destination again after evaporimeter 23 coolings;

The regeneration air system is that centrifugal blower 7 makes 6 heating of regeneration air heater via, and row advances atmosphere after runner 8 renewing zone desorption moisture absorptions again.

General structure of the present utility model is a combined type, is formed by hybrid filtering section 1, freeze drying section 2, rotary wheel dehumidifying section 3, mixed wind temperature descending section 4 and 5 five unit combination of air supply section.The hybrid filtering section is mixed new wind and return air, and mixing air is carried out filtration treatment, mainly comprises new air valve, primary retirn air valve and roughing efficiency air filter.The freeze drying section is carried out the wet process of falling in early stage to air, mainly comprises refrigeration components and parts such as evaporimeter, water-cooled condenser, compressor, hand valve, device for drying and filtering, magnetic valve, heating power expansion valve.The rotary wheel dehumidifying section is handled the moisture absorption that air carries out the degree of depth, mainly comprises runner, heater and centrifugal blower, runner by absorption, fall to attachedly recycling again and again.The hybrid cooling section is mixed heated dry air and the secondary return air after runner is handled, and, mainly comprise refrigeration components and parts such as secondary return air valve, evaporimeter, water-cooled condenser, compressor, hand valve, device for drying and filtering, magnetic valve, heating power expansion valve to the mixing air processing of lowering the temperature.Air after air supply section will be handled is transported to the destination, mainly comprises centrifugal blower, damping device and electrical apparatus control system.The utility model can adopt easily the PLC control mode according to temperature, humidity index controls, the major control heater add heat, new wind air-valve, primary retirn air air-valve and secondary return air air-valve open degree reach the purpose that adjusts wind-warm syndrome humidity.

3, beneficial effect: existing cooled dehumidifier unit generally can only satisfy the humidity requirement more than 45%, and single rotary dehumidifier initial cost and operating cost are all higher, and the stand-alone device volume is bigger, can not pass through short and small door opening smoothly, the utility model integrates direct vaporation-type freeze drying and rotary wheel dehumidifying advantage, and dependable performance is stable, and energy-saving effect is obvious, the cost performance height, equipment adopts fabricated structure simultaneously, has solved a transportation and a difficult problem of installing.The utility model utilizes direct sweat cooling dehumidifying of refrigerant and cooling, collects main frame, end and is controlled in one, has saved traditional loaded down with trivial details chilled water system, the refrigerating efficiency height, and on-the-spot needs wiring, takes over and can move.

The utility model has organically combined the advantage of direct vaporation-type freeze drying and rotary wheel dehumidifying, brings into play its usefulness better.Very high for humidity requirement, the control dew-point temperature is low, requires particularly humidity is controlled at that (water capacity is lower than 6g/kg below 45% _Do) occasion, solved the problem of cooled dehumidifier unit cisco unity malfunction under low temperature and low dew point operating mode, solved single rotary wheel dehumidifying speculative investment height simultaneously, the problem that leaving air temp is uncontrollable and operating cost is high.

The utility model be applicable to the low wet type occasion of new wind, no new wind low wet type occasion, the human comfort type occasion of new wind etc. is arranged, both can add heat and adjust the rheumatism degree by adjusting regeneration, can adjust the wind-warm syndrome degree by regulating the return air ratio again, satisfy harsh air-out parameter request.
