Description
The present invention by number of patent application is: 200910045066.1, and name of patent application is: " regenerative dehumidification heat exchange device and preparation method thereof ", patent application is artificial: Shanghai Communications University, patent application day is: the patent on January 8th, 2009 is divided an application.
Technical field
The present invention relates to a kind of heat exchanger of refrigeration technology field, specifically is a kind of regenerative dehumidification heat exchange device.
Background technology
The air dewetting technology mainly comprises freeze drying, compressed air dehumidifying and drier dehumidifying several method.The compressed air dehumanization method need compress air, improves steam partial pressure, separates the acquisition dry air after steam condenses, and this method is effective in the little occasion of air quantity, but is unwell to big air quantity.Freeze drying is that air themperature is reduced to dew-point temperature, makes water in air divide condensation, reaches the purpose of dehumidifying.But this method stable performance, reliable continuity work are higher at high temperature, high humidity area application efficiency.At dew point is that 8 ℃～occasion more than 10 ℃ is effective.But also there is following shortcoming in freeze drying: (1) is subject to the temperature of cooling medium, and cooling and dehumidifying can't provide the air-supply operating mode of low dew point or ultralow dew point; (2) temperature, humidity can not realize independent control, often need air is at first handled lower temperature in order to reach lower humidity, and then with air heat, arrive the humiture requirement of air-supply, have so more wasted the energy; When (3) dew point that requires when air-supply is lower than below 4 ℃, because of conventional refrigeration system evaporator frosting problem, equipment operating efficiency will significantly reduce, and energy consumption increases greatly.
The drier dehumidifying mainly is to utilize the good moisture-absorption characteristics of drier to satisfy the purpose of dehumidifying.The drier dehumidifying mainly comprises solid dehumidifying and liquid dehumidifying.Solid dehumidifying is a capillarity of utilizing porous media with airborne water adsorption to the drier.Solid dehumidifying comprises fixed bed dehumidifying and rotary wheel dehumidifying again.Solid dehumidifying equipment is simple, under low humidity, still good effect on moisture extraction can be arranged, can reach-40 ℃～-60 ℃ with air-treatment to lower dew point, and drier dehumidifying technology and cooling coil combined can realize that humiture controls separately, improved indoor air quality.Liquid dehumidifying adopts the spraying of the liquid drier aqueous solution such as lithium chloride to absorb moisture.The drier dehumidifying can utilize low grade heat energies such as solar energy, used heat, it has overcome freeze drying and the total big shortcoming of power consumption of compressed air dehumidifying, and system has bigger ventilation and drier can be removed pollutant in the air and can guarantee indoor air quality.But also there is deficiency in desiccant dehumidification: at dehumidification process, when absorbing moisture, drier can emit a large amount of heats of adsorption, heat of adsorption raises the temperature of drier and causes the ability drop of the absorption moisture of drier, equally, heat of adsorption also can make the temperature of handling wind raise, and has so just increased handling the energy consumption of wind cooling.
Find through literature search prior art, in order to solve that temperature that heat of adsorption makes drier raises and the problem of ability drop that causes the absorption moisture of drier, people's [interior cooling close-coupled solid dehumidifying device experimental studies such as Yuan of BJ University of Aeronautics ﹠ Astronautics satellite, Zheng Yi, Beijing space flight and aviation college journal, in September, 2006, the 1101st page] study and made cooling close-coupled distributary dehumidifier in the adhesive type.This dehumidifier version is similar to the distributary plate-fin heat exchanger that belongs to compact heat exchanger with the heat exchange principle, it is the improved form of ordinary fixed bed formula dehumidifier, it sticks on silica gel particle on the fin of dehumidifier master limit flow of process air runner, consider that silica gel has higher heat of adsorption when absorbing moisture, main limit runner is cooled off by air-flow on dehumidifier time limit, compare with rotary dehumidifier, the cooling effect on inferior limit is tangible, solved the heat of adsorption problem of hygroscopic agent effectively, experiment shows that the dynamic hydroscopicity of silica gel is up to 12.4% in this dehumidifier.But this dehumidifier volume is bigger, and with conventional drying agent dehumidification equipment ratio, spread of unit volume few (metal structure gross mass 18.6kg, the gross mass of silica gel is 1.9kg) and distributary dehumidifier installation difficulty are bigger.In addition, the gaseous exchange coefficient of heat transfer is lower, and this also is unfavorable for the dehumidifying/regeneration of drier
