Description

Full heat-recovery air source dehumidifying drying all-in-one

[technical field]

The utility model relates to mechanical field, air-source field and drying field, relates in particular to a kind of full heat-recovery air source dehumidifying drying all-in-one.

[background technology]

Existing air-source drying technology mainly contains two kinds.

The first is that oven dry is independent mutually with dehumidifying, and the air-source oven dry is a cover system, and unit is split type; The independent humidity control machine is adopted in dehumidifying, uses needs to satisfy.There is following defective in this technology: 1, Drying unit itself does not possess dehumidification function, and the dehumidification rate of dehumidifier can and reduce along with the temperature rising, is higher than more than 35 ℃, does not substantially dehumidify.2, outer chance frosting in winter needs defrost, under low temperature condition, and poor effect, indoor temperature does not increase because of frequent defrost; 3, in the circulating-heating process, condensation temperature can uprise along with the rising of indoor temperature, causes the compressor return air temperature to raise, and has a strong impact on the service life of compressor.

Another kind is that the air source drying-machine group is adopted monoblock type, and dehumidifying is by high-power blower that hot and humid Bas Discharged is outdoor under the condition of high temperature, thereby reaches the oven dry purpose.Also there is following defective in this technology: 1, unit itself does not possess dehumidification function, only depends on forced-ventilated under the humid tropical condition, and drying effect can't guarantee.2, outer machine frosting in winter, defrost still fail to solve, and weak effect reaches instructions for use reluctantly after increasing powerful auxiliary electrical heater; Operating cost is high, and is not energy-conservation; 3, in the forced-ventilated hydrofuge process, can cause a large amount of heats to lose in vain, cause the wasting of resources.Simultaneously, drying room must be introduced from the external world new wind, has additionally introduced again the new air that contains a large amount of humidity, has greatly prolonged drying time.

[utility model content]

The utility model provides a kind of full heat-recovery air source dehumidifying drying all-in-one in order to solve the above-mentioned deficiency of prior art.It has realized that dehumidifying drying is integrated, and is reaching under the prerequisite of drying effect, realizes energy-saving and cost-reducing purpose, has greatly promoted user's effectiveness of operation.

Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of full heat-recovery air source dehumidifying drying all-in-one, comprise casing, heat regenerator, compressor, gas-liquid separator, electric cabinet, dehumidification system and drying system, described casing is provided with the return air entrance, new wind entrance and hot-blast outlet, described heat regenerator is arranged between dehumidification system and the drying system, described dehumidification system comprises circulating fan, evaporimeter, electric heating tube and forced-ventilated air-cooler, the forced-ventilated air-cooler is provided with the cold wind outlet, and described drying system comprises secondary condenser, centrifugal blower and condenser.

Operation principle of the present utility model: the return air entrance is connected with drying room with hot-blast outlet, High Temperature Moist Air enters unit through the return air entrance in the drying room, through the heat regenerator cooling, pressurizes by circulating fan afterwards, enter the evaporimeter cool-down dehumidification and become the low temperature dry air, dehumidification process finishes; The low temperature dry air heats up through heat regenerator; pass through again the secondary condenser secondary temperature elevation; by the air-supply centrifugal blower; after entering condenser and again heating up; become high temperature dry air, enter drying room by hot-blast outlet, high temperature dry air becomes again High Temperature Moist Air and enters unit through the return air entrance again; begin next circulation, until drying requirement is shut down.

The utility model advantage compared with prior art is: the system and device with two-stage total heat recovery, condensed in two stages, integrate dehumidifying drying, possessed stepped heating, the lasting ability that dehumidifies, also possessed hydronic function, frost-free, without defrost, take full advantage of the air-source heat exchange, energy-conserving and environment-protective.

Be specially:

1, two-stage total heat recovery

High Temperature Moist Air in the drying room through warm and humid air in becoming after the heat regenerator heat exchange, heats up to opposite side low temperature dry air simultaneously, realizes the one-level recuperation of heat; Again with enter evaporimeter after new wind mixes and become the low temperature dry air, realize the secondary recuperation of heat.By these two full recuperations of heat of process implementation.

2, condensed in two stages technology

In condenser dry air temperature-rise period, adopt the condensed in two stages technology, widen on the one hand air intake and the air-out temperature difference, improve leaving air temp, improve the drying efficiency of unit; Reduce on the other hand the refrigerant temperature that enters expansion valve, improve the condensation efficiency of equipment, thereby the efficiency of unit is provided; The 3rd, breeze fan can be placed between the condenser, when satisfying air current composition, guarantees the working environment of blower motor, improves the service life of motor.

3, dehumidifying drying one

Two-stage total heat recovery has guaranteed required heat in the evaporator evaporation process, has also realized simultaneously dehumidification function, after heating up through heat regenerator, secondary condenser, condenser, reaches the oven dry purpose, realizes the dehumidifying drying one fully.

4, stepped heating technology

Low temperature dry air after the flash-pot dehumidifying directly being heated under the condition that does not adopt any auxiliary thermal source more than 60 ℃, has promoted the drying efficiency of unit through heat regenerator, secondary condenser, three grades of intensifications of condenser greatly.

5, continue dehumidifying effect

The unit temperature-rise period is a lasting cyclic process, circulated air all must be through entering the evaporimeter dehumidifying again after the heat regenerator cooling, avoided having guaranteed dehumidification rate and the continuous service of evaporimeter because High Temperature Moist Air excess Temperature in the drying room affects dehumidification rate even unit operation.

6, heating tech

Unit first through heating up after twice cooling, has avoided condensation temperature too high and affect the equipment operation even can not work in the dehumidifying drying process again, can realize continuing circulating-heating, stable operation.

7, frost-free is without defrost

In the winter time between algid stage; the required heat of the inadequate evaporimeter of warm and humid airborne heat in after lowering the temperature through heat regenerator replenishes by the auxiliary electrical heater pipe, guarantees that frost does not appear in unit operation; guarantee that unit is in oven-dried condition always, improve serviceability.

8, utilize the air-source heat exchange

Between non-algid stage in winter, during through the required heat of the inadequate evaporimeter of warm and humid airborne heat in after the heat regenerator cooling, replenish by introducing the new wind-heat amount in outside, too much low temperature dry air is discharged by strong board air-cooler, realize the air-source heat exchange, reduce power consumption, improve the efficiency of unit, improve energy-saving benefit.
