The heat exchange process of air in air channel:
Air carries out exchange heat process when flowing fortune in the first air channel is as follows: outdoor air is sent into the first wind through the first breeze fan 11 and led to, first, air directly contacts by solution dehumidification unit 1 and with the low temperature and high concentration salting liquid sprayed through the first spray equipment 101 and carries out hot and humid area, cool-down dehumidification process is carried out to air, obtains the dry air that relative temperature is lower; Then, dry air enters adiabatic humidiflcation heat exchange unit 3, and directly contact with the running water sprayed through the 3rd spray equipment 301 and carry out hot and humid area, make that the relative humidity of air increases, temperature reduces further, heat is also passed by the first shower humidification closed circuit by the heat that running water absorbs in air; Subsequently, Cryogenic air enters interior cold air water heat exchange unit 4, and carries out heat exchange with the water system backwater flowed in the 4th heat-exchanger rig 401, and the heat that Cryogenic air absorbs water system backwater makes its temperature reduce, and realizes the object of refrigeration or generation cold water; Finally, air enters interior cold humidification heat exchange unit 5 again, and carry out hot and humid area with the running water sprayed through the 5th heat-exchanger rig 502, simultaneously stability solution dehumidification unit 1 is by the latent heat of phase change of the first heat exchange circulation circuit transmission to interior cold humidification heat exchange unit 5, and air to become after saturation state outside discharge chamber.
The process of carrying out exchange heat when air flows in the second air channel is as follows: outdoor air sends into the second air channel through the second breeze fan 12, and first, air enters gas gas plate type heat exchanger 6; Then air enters regeneration of waste liquor unit 2 and carries out hot and humid area with the salting liquid sprayed through the second spray equipment 201, and air themperature is raised, and relative humidity increases; Last air is again by outside gas gas plate type heat exchanger 6 discharge chamber.In the process, just enter the air of gas gas plate type heat exchanger 6 outdoor, and can carry out gas gas exchange heat by the air entering gas gas plate type heat exchanger 6 after regeneration of waste liquor unit 2, the air themperature just entering gas gas plate type heat exchanger 6 is outdoor raised, its relative humidity is then reduced, this more can be conducive to the constant regeneration of salting liquid, thus improves efficiency and the usefulness of overall unit.
Salting liquid dehumidifying regeneration cycle process and heat exchange process wherein:
Low temperature dense saline solution is sprayed by the first spray equipment 101 in solution dehumidification unit 1, and directly contact with the air by the first air channel wherein, partial pressure of water vapor now in air is higher than the surface vapor pressure of salting liquid, salting liquid can absorb the moisture in new wind thus the dehumidification treatments realized air, due to the moisture absorbed in air, concentration reduces dense saline solution, after spray, salting liquid falls the first liquor box 103, and flows in rare salting liquid tank 14; By rare salting liquid pump 8, rare salting liquid is pumped into from rare salting liquid tank 14 second spray equipment 201 of regeneration of waste liquor unit 2 subsequently, carry out spraying in regeneration of waste liquor unit 2 and directly contact with the air by the second air channel wherein and carry out hot and humid area, partial pressure of water vapor now in air is lower than the surface vapor pressure of salting liquid, operative liquid water in salting liquid can become gaseous state and enter in air, thus make salting liquid regeneration dense saline solution, after spray, salting liquid can fall the second liquor box 203, and flows into dense saline solution tank 13; The first spray equipment 101 be pumped into from dense saline solution tank 13 by dense saline solution again in solution dehumidification unit 1 by dense saline solution pump 7 subsequently carries out spray dehumidification treatments, and iterative cycles like this runs.In the process, when solution dehumidification unit 1 dehumidifies to the air in the first air channel, can discharge latent heat of phase change, latent heat of phase change gives interior cold humidification heat exchange unit 5 by the first heat exchange circulation circuit transmission; When regeneration of waste liquor unit 2 carries out salting liquid regeneration process, need heat and absorb latent heat of phase change, its heat needed is provided by external heat source by the second heat exchange circulation loop.
