Abstract
The multi-stage heat exchanger consists of several serially connected heat exchange units and the containing casing. Each of the heat exchange units consists of air inlet side, air outlet side and separating partition board and there are inlet air filtering layer in the air inlet side and outlet air filtering layer in the air outlet side. There are liquid pool filled with liquid below the inlet air filtering layer and the outlet air filtering layer, liquid pump inside the liquid pool and liquid pipe connected to the outlet of the liquid pump. The multi-stage heat exchanger has high heat exchange efficiency at low temperature difference, capacity of recovering most of the energy during air exchange, humidifying effect, low power consumption and low production cost.
Description
Technical field:
The present invention relates to a kind of gas heat-exchanger, especially for the multifunctional multistage heat exchanger of low temperature difference gas high efficiency heat exchange and additional moistening and lowering temperature function.
Background technology:
Existing gas heat exchanger all be basically by the dividing wall type heat exchanger of heat conduction partition direct heat transfer or with the gas that needs heat exchange the heat regenerator of the indirect heat exchange by the accumulation of heat solid alternately.Because the coefficient of heat transfer between gas and solid is low especially, need very big heat exchange area just can reach certain heat exchange efficiency, real exchanger efficient is all very low, and manufacturing cost is all very high, particularly the heat exchange efficiency of low temperature difference gas (as the air inside and outside the air-conditioned room) is lower, so that does not have practical value.
Summary of the invention:
The purpose of this invention is to provide a kind of heat exchanger of high efficiency cheaply, the gas converting heat efficient of the low temperature difference is reached more than 80%, thereby the inside and outside low temperature difference gas exchange process of realization air-conditioned room reclaims most of energy, reduce the energy loss that ventilation brings greatly, also can add humidification and cooling function.
The object of the present invention is achieved like this: design a kind of new multistage heat exchanger, this heat exchanger is made up of a plurality of heat exchange units that are cascaded 1 and the housing 2 that contains them, and each heat exchange unit is made of air inlet side 11, exhaust side 12 and the dividing plate 13 of separating them.Air inlet filter gas-bearing formation 111 is arranged in the air inlet side, place the following liquid pool 112 of air inlet filter gas-bearing formation, place the infusion pump 113 in the liquid pool and be connected the woven hose 114 that infusion pump exports; Exhaust filter gas-bearing formation 121 is arranged in the exhaust side 12, place the following liquid pool 122 of exhaust filter gas-bearing formation, place the infusion pump 123 in the liquid pool and be connected the woven hose 124 that infusion pump exports.Air inlet filter gas-bearing formation, exhaust filter gas-bearing formation are made by good air permeability, hygroscopic material (the gas filtration humidification fabric of various two-dimentional water distributions, the organic or inorganic gas filtration of three-dimensional water distribution add wet stock as is well known) that the surface area rate is big.Fill certain liquid (water or liquid hygroscopic agent) in each liquid pool.Liquid pool is led in the infusion pump import, and woven hose leads to the top of corresponding filter gas-bearing formation respectively, and tube wall has spray hole.Infusion pump can be used known water pump, and also useable electric moter 115,125 drives by public axle 116,126 respectively and places the impeller of each liquid pool to realize.The thin plate (as aluminium sheet) that dividing plate 13 usefulness thermal conductivity are good is made corrugated, to increase heat exchange area.The air inlet side lontitudinal series of each heat exchange unit forms inlet channel (I-I), and the exhaust side lontitudinal series forms exhaust passage (O-O).
If do not need during heat exchange every wet, then air inlet filtering layer and exhaust filtering layer can a shared liquid pool and infusion pumps, and dividing plate therebetween also need not heat conduction, need not to make corrugated.
During the work of this multi-stage heat-exchanger, two strands of gases that need carry out heat exchange with external force drive (as blower fan etc.) respectively reverse flow in passage, press rightabout and see through each successively and filter gas-bearing formation through inlet channel and exhaust passage.Infusion pump is delivered to each filter gas-bearing formation with the liquid in the liquid pool, carry out flowing back into liquid pool after the heat exchange with the gas by the filter gas-bearing formation, the liquid in liquid in the liquid pool of each heat exchange unit inlet channel and the exhaust passage liquid pool carries out heat exchange (when the intermediate thermal conductivity dividing plate is arranged) or direct mixed heat transfer (during not heat conduction of central dividing plate) by heat conduction baffle therebetween.Since in the filter gas-bearing formation between the very big and liquid of the heat exchange area of liquid and gas the heat exchange efficiency of direct heat transfer or indirect heat exchange all very high, so it is very approaching to see through two strands of gas temperatures of each heat exchange unit, reverse flow is taken a breath through two strands of gases of heat exchanger like this step by step, thereby make the inlet temperature of the outlet of air inlet side and exhaust side very close, as long as heat exchange unit is abundant, reclaim the energy more than 80% in the time of just can realizing taking a breath at an easy rate.When being used for the calefactory ventilation, the saturated hygroscopic agent of the liquid in the liquid pool; When being used for the room ventilation of the no air-conditioning in refrigeration air-conditioner room or xeothermic area, the liquid in the liquid pool is water or unsaturation hygroscopic agent, also can carry out moistening and lowering temperature to air in ventilation, further conserve energy.
The advantage of this multi-stage heat-exchanger is can reach very high heat exchange efficiency when being used for the gas converting heat of the low temperature difference, be used for the ventilation of air conditioner room and can reclaim most of energy, the room ventilation energy moistening and lowering temperature that is used for the no air-conditioning in xeothermic area, and the energy that for this reason consumes is more much lower than existing air-conditioning, and the device fabrication cost is also much lower.
