Technical field
The present invention relates to the technical field of dehydrating unit, utilize capillary power-actuated hollow-fibre membrane liquid dehumidifying device more particularly, to one.
Background technology
The quality of health and room air is had an impact by air through moisture, needs air dewetting to reach comfortable level.Current dehumanization method mainly includes following several: the dehumidifying of cooling and dehumidifying, electrochemistry, desiccant dehumidifying etc..Air themperature is dropped to below its dew point temperature by cooling and dehumidifying method exactly so that the moisture in air condenses at cooler surface.Owing to the method needs the temperature of air is dropped to below its dew point temperature, need to consume substantial amounts of energy.Electrochemistry dehumidifying is to utilize steam to resolve into oxygen and proton at galvanic anode, then proton translocation to negative electrode generates hydrogen molecule or is combined generation water with oxygen, reduces the moisture in air with this.The method needs DC source, electric energy to be consumed, and engineer applied is less.Desiccant dehumidifying method is to utilize desiccant to contact with humid air, is that the moisture in air is delivered in desiccant.Desiccant dehumidifying method can be divided into solid absorption dehumidifying method and liquid absorption dehumidifying method.Owing to the regeneration temperature of solid absorbent is higher, therefore its energy consumption is bigger.Liquid absorption dehumidifying method generally uses LiCl, CaCL2, etc. the Organic substance such as saline solution or 2,2'-ethylenedioxybis(ethanol). as liquid desiccant, air is dehumidified.But, the complicated structure of the existing device utilizing liquid absorption dehumidifying method, dehumidifying inefficient.
Summary of the invention
The present invention is to overcome the number of drawbacks described in above-mentioned prior art, it is provided that one utilizes capillary power-actuated hollow-fibre membrane liquid dehumidifying device, its simple in construction, can improve the efficiency of dehumidifying, not produce environment and pollute, energy-saving clean.
For solving above-mentioned technical problem, the technical solution used in the present invention is: one utilizes capillary power-actuated hollow-fibre membrane liquid dehumidifying device, wherein, including being located at the liquid dehumidifying agent container of bottom, multiple hollow fiber film tubes of being located on liquid dehumidifying agent container, multiple hollow fiber film tubes form doughnut tube bank, liquid desiccant container content has liquid desiccant, and multiple hollow fiber film tubes connect the liquid desiccant in dehumidizer container, and capillary force drives the flowing of dehumidification solution；
Described doughnut tube bank is outside is provided with shell, and shell is provided with air intake and air outlet slit, and humid air stream flows into multiple hollow fiber film tubes through air intake, and steam can be taken away in the absorption of dehumidified solution, flows out the air being dried from air outlet slit.The top of described multiple hollow fiber film tubes is additionally provided with vaporising device.Described multiple hollow fiber film tubes are vertically located on liquid dehumidifying agent container.
In this programme, liquid desiccant is LiCl, 2,2'-ethylenedioxybis(ethanol). etc., hollow fiber film tube is PVDF, PTFE etc., substantial amounts of hollow fiber film tube flocks together and forms a doughnut tube bank, the tube bank of this fiber is placed in the cabinet of a cross-current configuration, dehumidification solution flows in hollow fiber film tube, and air flows outside hollow fiber conduit.Doughnut tube bank is vertically placed, and lower end contacts with filling liquid dehumidifying agent container, and upper end adds speed evaporation device with one and is connected.
Owing to the diameter (micron order) of hollow fiber film tube is the least, under capillary action, by the length of conservative control hollow fiber film tube, the liquid desiccant of bottom will be drawn into top.Humid air stream is when hollow-fibre membrane, and steam can be taken away in the absorption of dehumidified solution, and from the outflow of cabinet air outlet slit is more dry air.In order to improve the efficiency of dehumidifying, connecting a vaporising device at hollow fiber conduit bunchy top end, the evaporation of the dehumidification solution outreached by quickening improves dehumidification solution flow velocity in hollow fiber conduit, thus improves dehumidification rate.
Further, described air intake is respectively arranged on the relative position of shell with air outlet slit.So, air flows into from one end of shell, other end at shell flows out, the flow direction of liquid desiccant is vertical, the flow direction of air is horizontal, humid air stream is when hollow-fibre membrane, and steam can be taken away in the absorption of dehumidified solution, and from the outflow of cabinet air outlet slit is more dry air.
Compared with prior art, provide the benefit that: the present invention make use of capillary force to drive the flowing of dehumidification solution dexterously, substantially need not consume the energy of other forms；The evaporation of the dehumidification solution on top can be increased by suitable ventilation, thus improve the efficiency of dehumidifying, the recyclable recycling of solution of evaporation, also surrounding will not be produced and pollute, energy-conservation clean again.
