Description
Technical field
The present invention relates to dehumidifier, relate in particular to a kind of cross flow internally-cooled solution dehumidifying device and method thereof.
Background technology
Humidity in indoor environment is excessive all can cause adverse effect to human comfort and health.Therefore refrigerated air-conditioning system except controlling temperature, also will be born the task of dehumidifying usually.Traditional refrigerated dehumidification method adopts surface-cooler to come cool-down dehumidification, and this just need to make the evaporating temperature of refrigeration system lower than the dew-point temperature of air.If be only in order to guarantee indoor temperature, evaporating temperature can improve a lot.So not only cause unnecessary energy resource consumption, more be difficult to adapt to the variation of humiture ratio.And the condensate water of refrigerated dehumidification is easily grown mould, and indoor air quality is caused adverse effect.For these problems, industry generally believes that effective solution route is with separately independent control of humiture, namely adopts independent dehumidifier that humid air is processed at present.The solution dehumidification mode is just more and more used due to the advantage that possesses at aspects such as energy savings and raising indoor air qualities.
Solution dehumidification uses the salting liquid with hygroscopic nature as working media, consists of Major Systems by dehumidifier, regenerator and circulating pump.When air contacted with the absorption liquid that sprays in dehumidifier, airborne moisture was absorbed by solution and dehumidifies.Solution after absorption moisture is delivered to regenerator by circulating pump, contacts with the regeneration air that is heated by heat(ing) coil, and the moisture in solution evaporates and follows the regeneration air discharge outdoor, and the solution that in regenerator, concentration improves is sent into dehumidifier by circulating pump again.
Whether dehumidifier is the critical component of solution dehumidification system, cooling according to adding extraneous cold to carry out to dehumidification process, dehumidifier can be divided into two large classes: internally cooled dehumidifier and heat insulation-type dehumidifier.In the heat insulation-type dehumidifier, the dehumidified solution of the steam in humid air can discharge latent heat of phase change when absorbing, and the temperature of dehumidification solution is raise, and dehumidification rate descends.The internally cooled dehumidifier is in the dehumidified solution dehumidification of air, with extraneous low-temperature receiver (cooling water, cooling-air etc.), the part latent heat that dehumidification process discharges is taken away, and has reduced the irreversible loss of dehumidification process, thereby has improved dehumidification rate.The distributary type dehumidifier of enhanced heat exchange belongs to the internally cooled dehumidifier.
Although but liquid dehumidifying has continuous dehumidifying, regeneration action very fast sterilization and rinse air, can obtain the stable advantages such as dry air, because solution is to contact with air with vaporific, need prevent that solution from taking out of or dispersing.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing solution dehumidification system, a kind of cross flow internally-cooled solution dehumidifying device and method thereof are provided.
Cross flow internally-cooled solution dehumidifying device by side by side or the series connection a plurality of Dehumidifying elements form, Dehumidifying element comprises distributive pipe, collector pipe, capillary, sleeve pipe, collecting tank, liquid-adsorption layer; The distributive pipe vertical parallel is provided with many capillaries, and the end of many capillaries is provided with collector pipe, is provided with collecting tank below collector pipe, and distributive pipe is provided with sleeve pipe outward, and every capillary evenly closely is wound around one or more layers liquid-adsorption layer outward.
The material of described liquid-adsorption layer is corduroy.
Cross flow internally-cooled solution dehumidifying method is: behind the gap between dehumidification solution inflow sleeve pipe and distributive pipe, due to action of gravitation, will be along the capillary flow downwards, and the capillary pumped effect that covers the liquid-adsorption layer of extracapillary will make dehumidification solution be evenly distributed on extracapillary, thereby exchange with the humid air generation caloic that level is passed, absorb steam and latent heat of phase change in humid air, meanwhile with capillary in cooling water generation heat exchange, the collecting tank of the last dehumidified device of dehumidification solution bottom is collected and is recycled; Cooling water flows into capillary from distributive pipe, with the dehumidification solution generation heat exchange of extracapillary, absorbs the heat that the water vapour condensation discharges, and then recycles via the collector pipe outflow; When humid air passes from level between parallel capillary, contact with dehumidification solution and the heat and mass effect occurs, thereby reaching effect on moisture extraction.
Described dehumidification solution is LiCl, CaCl
2Or LiBr solution.
The beneficial effect that the present invention compared with prior art has:
1) process the humid air of equal in quality flow, the liquid inventory that the solution quality flow-rate ratio prior packed tower dehumidifier that this dehumidifier consumes consumes is much smaller;
2) air wide pre. drop that causes in the process of processing humid air is lower, enters after treatment in indoor air and can not carry solution droplets;
3) compare with traditional liquid dehumidifier with the wheel solid adsorption moisture eliminator, this dehumidifier has better wet-out property.
