Problems solved by technology

[0002] Commonly used dehumidification methods include freezing dehumidification (liquid dehumidification), solid dehumidification, etc., both of which need to be driven by high-grade energy such as electricity or heat. Although low-grade unsaturated air such as air-conditioning drying exhaust is low-grade energy, solid dehumidification Regeneration of solvent or liquid desiccant can be regenerated using low temperature dry air, currently low temperature unsaturated air has not been effectively used for dehumidification

Embodiment 1

[0034] like figure 1 As shown, the device for dehumidifying using low-temperature unsaturated air in the present invention includes a dehumidification device 10, a precooling device 20, a housing 30, and a partition 40. The partition 40 divides the housing 30 into a regeneration channel 33 and a dehumidification channel 34. The dehumidification device 10 The regeneration side 11 of the dehumidification device 10 is placed in the regeneration channel 33 , and the dehumidification side 12 of the dehumidification device 10 and the pre-cooling device 20 are both placed in the pre-cooling device 20 . The low-temperature unsaturated air A1 regenerates the desiccant through the regeneration side 11 of the dehumidification device 10, and the treated air A3 is first cooled to a saturated state A4 by the pre-cooling device 20, and then dehumidified by the dehumidification side 12 of the dehumidification device 10 to become A5 , the low-temperature unsaturated air A1 and the processed ai...

Embodiment 2

[0037] like figure 2 As shown, the dehumidification device 10 adopts an integral membrane dehumidification device, the solution L is on the inside of the membrane, and the air is on the outside of the membrane. The solutions on the dehumidification side 12 and the regeneration side 11 of the membrane dehumidification device are connected, and the solution is realized through diffusion or different densities. exchange. The difference between the air process and the first embodiment is that a heating element 100 is added between the membranes on the regeneration side 11 of the dehumidification device 10, and a cooling element is added between the membranes on the dehumidification side 12 of the dehumidification device 10. 90; that is, for the dehumidification side, there is a cooling element 90 to cool the air, and for the regeneration side, there is a heating element 100 to heat the air. In the figure, there are both the cooling element 90 and the heating element 100, or only ...

Embodiment 3

[0039] like image 3 As shown, the dehumidification device 10 adopts a separate dehumidification membrane. In this embodiment, the dehumidification device using low-temperature unsaturated air also includes a pump 53 and a solution tank 50, the regeneration side 11 of the dehumidification device 10, and the dehumidification side 12 of the dehumidification device 10. , the pump 53 and the solution tank 50 are connected into a closed loop through a pipeline 54 .

[0040] Solution circulation is driven by pump 53 .

Abstract

The present invention discloses a method and an apparatus for adopting low temperature unsaturated air to dehumidify. The apparatus comprises a dehumidifying device, a pre-cooling device, a housing and a separation plate, wherein the housing is divided into a regeneration channel and a dehumidifying channel through the separation plate, the regeneration side of the dehumidifying device is arranged inside the regeneration channel, and the dehumidifying side of the dehumidifying device and the pre-cooling device are arranged inside the pre-cooling device. According to the present invention, low temperature unsaturated air performs regeneration on a dehumidifying agent through the regeneration side of the dehumidifying device, treated air is cooled to achieve a saturated state through the pre-cooling device, and then is dehumidified through the dehumidifying side of the dehumidifying device, and the low temperature unsaturated air and the treated air are subjected to counter current; and low temperature unsaturated air including exhaust air of air conditioning recirculated air is adopted to dehumidify. The method and the apparatus have characteristics of energy saving, high efficiency, convenience, simpleness and the like.

Description

technical field [0001] The invention relates to a method and device for dehumidifying by using low-temperature unsaturated air, in particular to a method and device for dehumidifying fresh air by using return air discharged from an air-conditioned environment. Background technique [0002] Commonly used dehumidification methods include freezing dehumidification (liquid dehumidification), solid dehumidification, etc., both of which need to be driven by high-grade energy such as electricity or heat. Although low-grade unsaturated air such as air-conditioning drying exhaust is low-grade energy, solid dehumidification Regeneration of solvent or liquid dehumidifiers can be regenerated using low-temperature dry air, and low-temperature unsaturated air has not been effectively used for dehumidification at present. Contents of the invention [0003] The object of the present invention is to provide a method and device for dehumidification using low-temperature unsaturated air to a...
