Described doughnut tube bank outside is provided with shell, and shell is provided with air intake and air outlet slit, and humid air stream flows into a plurality of hollow fiber film tubes through air intake, and steam can be taken away in dehumidified solution absorption, from air outlet slit, flows out dry air.The top of described a plurality of hollow fiber film tubes is also provided with vaporising device.Described a plurality of hollow fiber film tubes are vertically located on liquid dehumidifying agent container.
In this programme, liquid desiccant is LiCl, triethylene glycol etc., hollow fiber film tube is PVDF, PTFE etc., a large amount of hollow fiber film tubes flocks together and forms a doughnut tube bank, this fiber tube bank is placed in the plastic casing of a cross-flow form, dehumidification solution flows in hollow fiber film tube, and air flows outward at 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 and is connected with one.
Because the diameter (micron order) of hollow fiber film tube is very little, under capillarity, by the length of reasonable control hollow fiber film tube, the liquid desiccant of bottom will be drawn onto top.Humid air stream is when hollow-fibre membrane, and steam can be taken away in dehumidified solution absorption, and what from plastic casing air outlet slit, flow out is more dry air.In order to improve the efficiency of dehumidifying, at hollow fiber conduit bunchy top end, connect a vaporising device, the evaporation of the dehumidification solution outreaching by quickening improves the flow velocity of dehumidification solution in hollow fiber conduit, thereby improves dehumidification rate.
Further, described air intake and air outlet slit are located at respectively on the relative position of shell.Like this, air flows into from one end of shell, flow out other one end at shell, 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 dehumidified solution absorption, and what from plastic casing air outlet slit, flow out is more dry air.
Compared with prior art, beneficial effect is: the present invention has utilized capillary force to drive flowing of dehumidification solution dexterously, does not substantially need to consume the other forms of energy; By suitable ventilation, can increase the evaporation of the dehumidification solution on top, thereby improve the efficiency of dehumidifying, the recyclable recycling of solution of evaporation, yet can not produce and pollute surrounding environment, energy-conservation clean again.
