Because solution dehumidifying air-conditioning system in the superiority of removing on the latent heat load, obtains everybody extensive concern in recent years gradually, becomes the research focus of field of Refrigeration and Air-conditioning.Solution dehumidification is that a kind of Physical Absorption principle of utilizing is carried out the humidity Treatment Technology to air, and the quality of its wet-out property is weighed with the size of its surface vapor pressure.Can know that by Raoult's law along with the increase of solute concentration, the steam partial pressure of solution surface reduces gradually.Actual dehumidification solution, its performance departs from Raoult's law, and is minus deviation, thereby actual dehumidification solution has stronger wettability power.The surface vapor pressure of solution is the function of solution temperature and concentration, along with the rising of the reduction of solution temperature, solution concentration and reduce.Pressure reduction between the steam partial pressure of the air that is processed and the surface vapor pressure of dehumidification solution is the driving force that moisture is transmitted to dehumidification solution by air; Thereby the dehumidification solution surface vapor pressure is low more; Under identical treatment conditions; The dehumidifying effect of solution is strong more; With the humid air that is contacted reach balance the time, humid air has lower relative humidity.Solution dehumidifying air-conditioning system can effectively utilize low-grade energy and backheat to accomplish the regeneration of solution, and in solution dehumidifying air-conditioning system, energy exists with the form of chemical energy rather than heat energy in dehumidification solution, thereby its accumulation of energy ability is very big.Because solution has corrosivity, traditional heat exchanger metal material such as aluminium, copper etc. are corroded easily and are damaged heat exchanger.For overcoming this deficiency, the filler that patent of the present invention proposes adopts foamed aluminium, is a kind of corrosion-resistant, low-density, high-specific surface area and porous material with fine heat-insulating property.The foamed aluminium filler with in cold/interior heat pipe form the heat and mass cell cube, this cell cube be simple in structure, be easy to process novel in cold/interior pattern of fever solution dehumidifying and regenerating device.
Summary of the invention
Technical problem:The technical problem that the present invention will solve provides high, the simple in structure solution dehumidifying and regenerating device of a kind of efficient.
Technical scheme:For solving the problems of the technologies described above; The present invention proposes a kind of solution dehumidifying and regenerating device, this device comprises housing, be arranged on the solution influent stream pipe of housing internal upper part, be arranged on middle part in the housing by filler and in the heat and mass cell cube formed of cold/interior heat pipe, the dehumidifying actified solution delivery line that is arranged on housing bottom; Side at the housing middle part is provided with the inlet humid air, and opposite side is provided with the outlet humid air; The input of cold in the influent stream pipe connects/interior heat pipe, the output of cold in outflow tube connects/interior heat pipe; The part of solution influent stream pipe in housing is provided with knockout.
Preferably, described filler adopts foamed aluminium.
Preferably, the air port perhaps is set up and down respectively in the housing both sides.
Beneficial effect:Cold in the employing/interior heat pipe is installed in the inner method of filler; Because foamed aluminium has high-specific surface area, porous and the good characteristics of heat conductivility performance; Make solution and air can keep the operating temperature of needs, the contact area of solution and humid air increases, and has strengthened mass transfer effect.
