Description
Technical field
The present invention relates to a kind of air dehumidifier, particularly a kind of phase-change adsorption air dehumidifier.
Background technology
The temperature of air, humidity are two important parameters that air-conditioning process need be controlled, the 20%-40% of dehumidifying energy consumption duty adjusting system energy consumption; Traditional cooling and dehumidifying method supply water temperature is low, and cold engine efficiency is low, and dehumidifying back air themperature is low, also needs heat again for reaching ventilation state point, causes irreversible loss serious.So people have been developed temperature, humidity is separated control technology, promptly airborne water vapour is removed by special dehumidification system, and air-conditioning system is only born the sensible heat of handling air.Generally this class dehumidification system is divided into solution dehumidification system, ADSORPTION IN A FIXED BED dehumidification system and runner absorption type dehumidification system three major types, they all belong to equilibrium separation process.Wherein, the ADSORPTION IN A FIXED BED dehumidification system have system simple, implement easily, moving component is few, the exchange of gas-solid caloic fully, characteristics that irreversible loss is little, have bigger using value.The ADSORPTION IN A FIXED BED dehumidification system can be divided into internally cooled and heat insulation-type two classes.The characteristics of internally cooled system are to install cooling coil in adsorbent bed, take away the heat that absorption latent heat and regenerative process produce; It has, and volume is little, the advantage of continuously-running, but shortcoming is that system's complex structure, running gear are more.The heat insulation-type internal system is not established cooling coil, and it is divided into two kinds of continuous operation mode and gap mode of operations again.Work as running hours, adopt two handover operations, another bed dehumidifying during a bed regeneration; Its shortcoming be when regeneration system accumulated a large amount of heat energy, switch to dehumidification mode after, the heat that major part is accumulated will be born by processed air, and its outlet temperature is significantly increased, and increase the weight of the processing burden of follow-up link.When working for the gap, adsorbent needs regular replacing and regeneration separately, and owing to there is not interior cold-working usefulness, the heat of adsorption that adsorption process produces will make bed temperature raise gradually, thereby reduced the steam potential difference between adsorbent and the air, finally influenced effect on moisture extraction.This shows that processed air exit temp height and effect on moisture extraction are low to be two big major defects of heat insulation-type fixed adsorption bed.
Summary of the invention
It is good and can guarantee the phase-change adsorption air dehumidifier that processed air exit temp is low that the technical problem to be solved in the present invention provides a kind of effect on moisture extraction.
In order to solve the problems of the technologies described above, the invention provides a kind of phase-change adsorption air dehumidifier, establish the phase transformation adsorptive reactor of cavity in comprising, the open top of phase transformation adsorptive reactor and bottom opening all are connected with cavity; Sealing links to each other with the regeneration air blast pipe with processed air discharge pipe respectively in open top, and sealing links to each other bottom opening with the regeneration air discharge pipe with processed air blast pipe respectively; The other end of regeneration air blast pipe links to each other with regenerated air heater, is respectively equipped with heat medium enter hose and heat medium produce hose on the regenerated air heater; Interior cold air pipeline is positioned at described cavity, and the sidewall that the phase transformation adsorptive reactor is all passed in the import of described interior cold air pipeline and outlet is connected with the external world.

Phase-change adsorption air dehumidifier of the present invention, the course of work is specific as follows:
1), absorption:
The insulation door I 4 that is positioned at import 21 places of cold air pipeline 2 all keeps closing with the insulation door II5 that is positioned at outlet 22 places; Stop valve I71 and stop valve III73 open, and stop valve II72 and stop valve IV74 close.
Processed air enters the bottom of the cavity 12 of phase transformation adsorptive reactor 1 by processed air blast pipe 63 under the promotion of extraneous blower fan; Slowly flow then, and accept the processing of the mixture 3 formed by adsorbent and phase-change material to the top of cavity 12; Discharge from processed air discharge pipe 61 at last.It is adsorbed that processed airborne part steam is adsorbed agent, thereby reduced the air water capacity; The heat of adsorption of emitting during water recovery is born jointly by phase-change material, adsorbent and processed air.
When the outlet water capacity of processed air and import were basic identical, when promptly whole phase-change adsorption air dehumidifier can't dehumidify work again, adsorption process finished.Just carry out following desorption work then.
2), desorption
Keep closing insulation door I4 and insulation door II5, close stop valve I71 and stop valve III73, open stop valve II72 and stop valve IV74.
Under the promotion of extraneous blower fan and through the regeneration air after regenerated air heater 8 heat treated, enter the top of cavity 12 by regeneration air blast pipe 62, slowly flow to the bottom of cavity 12, finally discharge from regeneration air discharge pipe 64.To the adsorbent processing of regenerating, along with the carrying out of regenerative process, the water capacity of adsorbent reduces this regeneration air and temperature increases in cavity 12.Can come the heating efficiency of regenerated air heater 8 is regulated by stop valve V75 on the adjusting heat medium enter hose 81 and the stop valve VI76 on the heat medium produce hose 82, thereby the temperature after regeneration air is heated is regulated in realization.Generally speaking, the temperature of the regeneration air after the adjusting heating is 100 ℃～120 ℃.
When regeneration air outlet water capacity and import water capacity are basic identical, the regenerative process end.Just carry out following cooling work then.
3), cooling
Keep closing stop valve I71 and stop valve III73, close stop valve II72 and stop valve IV74, open insulation door I4 and insulation door II5.
Under the hot pressing function in cavity 12, in entering from import 21, surrounding air in the cold air pipeline 2, discharges from exporting 22 at last; Carry out the sensible heat exchange by adsorbent in interior cold air pipeline 2 tube walls and the cavity 12 and phase-change material, thereby take away the heat of adsorbent and phase-change material.
When this cooling procedure proceeded to night, because environment temperature further reduces, the phase change material cool storage in the inner chamber became solid-state, and the cooling regenerative process finishes.
Afterwards, close insulation door I4 and insulation door II5, the cavity 12 of phase transformation adsorptive reactor 1 is kept and extraneous state of thermal isolation.By the time entered next working cycles again in second day, and promptly adsorbed successively again, desorption and these 3 steps of cooling.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present invention.Obviously, the invention is not restricted to above embodiment, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
