Description
Technical field
The present invention relates to a kind of desorption method and device, relate in particular to that a kind of mode of utilizing energising makes the material conduction and a kind of low energy consumption desorption method and apparatus of carrying out desorption.
Background technology
Common sorbing material has porous carbon material, zeolite, silica gel or the like; Organic volatile (volatile organic compound in can absorbed air; VOC) or moisture, usually be to realize continuous operation during use with multi-tower type structure or runner structure.When for example a certain tower adsorbed, another tower just carried out desorption and regeneration, when treating that absorption and desorption and regeneration reach capacity, just exchanged runner.If with rotary-type structure, then can on the area of runner, distinguish the zones of different of desorption and regeneration and absorption, through the rotation of runner, let material alternately through absorption and desorption and regeneration zone, reach the purpose of continuous running.
The method of regeneration desorption, lets the warm-up movement of molecule be enough to destroy sorbing material and be adsorbed intermolecular key knot power or attraction, and reaches the purpose of desorption through hot blast heating sorbing material and the molecule that is adsorbed nothing more than the hot blast through extreme temperatures.This kind desorption method must add hot-air earlier; Transmit desorption through the heat between air and sorbing material again,, add the efficiency of heating surface problem of heater itself by heat loss is arranged between air heater to the sorbing material easily; Therefore, the required energy loss of desorption is very big.In the compact product of this external ask for something, often lack the heater that enough areas are installed in the space, because heat exchange area is not enough, the surface temperature of heater itself is high when therefore adding hot-air, also causes extra radiation heat loss.
For example, Fig. 1 analyzes for the family expenses drip type dehumidifier energy resource consumption of using desiccant wheel, and the surface temperature of heater is high, and the electric energy that therefore most heater consumes is that the mode with radiation sheds.During the power consumption of the family expenses formula dehumidifier in figure one was analyzed, the amount of dripping is about 6.6 liter/day, and (20C, 60%RH), about 600 watts of heater power consumption wherein had 479 watts to be radiant heat, only has 121 watts to be used in and to add hot-air.
The rotary-type adsorption and dehumidification machine of prior art; All be with electric heater thermal regeneration sidewind; Improve the regeneration air temperature; The thermal desorption mechanism that adds of this technology mainly is divided into two partly: (one) air-flow heat exchange vaporization: produce thermograde with the heat cycles air-flow, with the moisture content in the dehumidification structure in the heat vaporization dehumidifying body that heat exchange was produced.Owing to need just can carry out the steam desorption, therefore need high energy consumption just can reach the target of drying dehumidification with high temperature air.(2) radiant heat vaporization: heating wire produces high temperature after through electric current in the heater, and this heat makes the hydrone in the structure in the dehumidifying body can directly absorb radiant heat vaporization desorption with photothermal form.Because radiations heat energy becomes the biquadratic direct ratio with surface temperature, the electric heater surface all is higher than more than 400 ℃, and radiations heat energy is high, and the steam desorption effect that is therefore produced is even more important far beyond the vaporization of the air-flow heat exchange in aforementioned () desorption.
By above-mentioned two vaporization mechanism analysis, the heated type regeneration desorption mode of prior art is no matter be that the heat cycles air-flow causes the indirect vaporizing desorption; Or radiant heat is when being absorbed by hydrone; Most of radiations heat energy is also absorbed by the dehumidifying body, therefore, causes inevasible power consumption source.In addition, radiations heat energy causes absorbent structure surface temperature to rise, and also is unfavorable for the absorption of hydrone, significantly reduces dehumidifying effect.Therefore heated type regeneration desorption method is to cause rotary-type dehydrating unit power consumption higher, the main cause that dehumidification rate reduces.
In order to overcome above-mentioned problem, as shown in Figure 2, it has disclosed and a kind ofly utilizes isoionic mode to replace prior art to add the mode sketch map of thermal desorption dehumidifying body moisture for Japanese publication spy opens 2001-179037.In this technology, utilize the electrode 11 and 12 that is arranged at Dehumidifying element 10 both sides to produce plasma Dehumidifying element 10 adsorbed moisture are broken away from.But in this technology, electrode 11 does not directly contact with Dehumidifying element 10 with 12, comes desorption Dehumidifying element 10 for utilizing point discharge to produce isoionic mode.
