Working condition of the present invention is the removal moisture drying temperature adjustment course of work:

Humid air by removing filler 9 in the wet channel, and contacts through solution pump 7, solution spraying pipe 8, the dehumidification solution that comes in solution tank 6 from air inlet 1 enters removal moisture drying part, is removed the moisture of being with, and emits heat, and the dry air after the dehumidifying is heated.Dry air after the heating arrives wind pushing cavity 18 via the air feeder vane wheel 11 that motor 12 drives, and after evenly mixing, by supply air duct converter 16, sets as required, or sends to working environment by the outlet of the dry-air blast after the dehumidifying 3; Or, send to working environment dehumidifying and temperature adjustment through dehumidification and temperature adjustment dry-air blast exit temperature adjustment interchanger 15.Temperature adjustment working medium enters temperature adjustment interchanger 15 by refrigerant import 34, returns through refrigerant outlet 35 then.Air intake also can utilize the return air in the working environment as required.

The dehumidification solution cyclic process: a certain amount of dense dehumidification solution enters the removal moisture drying part by the import 10 of dense dehumidifying liquid from regenerating section, spray to filler 9 through shower 8, contact with vertical air equably by filler 9, absorb airborne moisture, emit heat, fall into dehumidification solution groove 6, each grade solution forms self-loopa in the dehumidification solution groove, and has a spot of solution to flow into next stage successively.In the afterbody, the weak solution after a certain amount of moisture absorption is sent to concentrate in the regenerating section and regenerates by outlet 5, recycles.

The regeneration required air enters regenerating section work carry out heat exchange through the preheat exchanger 30 of air inlet 21 and interior installation thereof and bybrethaid 29 and the used heat air of getting rid of from regenerating section after, and the used heat air after heat exchange is discharged byexhaust duct 28 and exhaust outlet 20 then.

Regenerative heat exchanger andfiller 24 are used for the energy of heated solution.Thermal source is via import 33, tube connector 32, enters regeneratedheat exchange filler 24, passes through tube connector afterwards, enter preheat exchanger 30 pre-heating intakings after, return thermal source through exporting 31, form complete cycle.

The reproduction operation process:

Dehumidification solution after the moisture absorption (can adopt lithium salt solution), concentration reduces, and dehumidification rate reduces, by dilute solution inlet 36,actified solution shower 26, solution sprayingliquid distributor 25, be heated through regeneratedheat exchange filler 24, wherein moisture is evaporated, and is taken away by hot-air from bottom to top.Solution after concentrating falls intoreservoir 23, to the removal moisture drying part, supplies the usefulness of dehumidifying through flow control valve 38, concentrated solution outlet 37.Solution concentration regeneration is the isothermal single-stage, and it is multistage also to can be the branch gradient.Solution has circulation of one's own, repeated regeneration through pump group 19,solution spraying pipe 26 in every grade.Between level and the level small volume of solution one-way flow is arranged.

By above-mentioned situation as can be known, the present invention utilizes (lithium salts) solution or two or more mixed solution to make hygroscopic agent, on the one hand, hygroscopic agent is by directly contacting with humid air, remove its moisture content, as drying medium, it is become in allowing humidity range can adjust dry air arbitrarily, on the other hand, humid air loses entrained steam simultaneously, emits a large amount of heats, with the heating of the dry air after the dehumidifying, the temperature of dry air can be regulated in 0-120 ℃ of (or bigger) scope as required, is easy to realize any requirement of air themperature and humidity.Simultaneously, because lithium salt solution directly contacts with air, reach effects such as air disinfection, dedustings, the air after dry the processing is sent to working environment.In brief, the present invention is a dehumidification and temperature adjustment, and humid air directly contacts with certain density concentrated solution through filler, dries out, and emits heat, and temperature raises, and is sent to working environment as drying medium;

Concentrate regeneration, hygroscopic agent obtains moisture, and concentration reduces, and is corresponding, and its dehumidification rate reduces, and must form complete cycle, and hygroscopic agent recycles, and reduces operating cost greatly.This process can be widely used in grain drying dehydration, tobacco leaf dehydration processing, or temperature, humidity is had the environment of particular requirement.As pharmacy, electronics processing enterprise, storage industry, other agricultural storages, high humidity area dehumidifying, Industrial Stoves air preheat etc.Consumes energy is mainly used to solution regeneration.Both can be electric energy (heat pump driving), also can be low-temperature heat source (hot water driving), various fuel, solar energy, various waste heat waste gas etc.

Be not subjected to the influence of external condition during the present invention uses, but all-weather work is effective, expense is low, and speed is fast, has opened up the new way of removal moisture drying temperature adjustment, new mode, and popularizing application prospect light has the creationary contribution of developing.
