Gas treatment device and control method thereof

Abstract

The invention provides a gas treatment device and a control method thereof. The gas treatment device is provided with an annular filter layer, wherein the annular filter layer rotates circularly in a liquid storage part; the gas is treated after passing the annular filter layer; through an attachment separation device separated from the liquid storage part, attachments of the annular filter layer can be separated from the outer part of the liquid storage part, so that lots of the attachments cannot return back to the liquid storage part along with the filter layer, the problem of secondary pollution to the filter layer after cleaning in the prior art can be solved, secondary pollution to the filter layer is reduced, and the gas treatment quality is improved. According to the control method of the gas treatment device, a driving device is started, and a windward side of the annular filter layer is controlled to rotate in the direction from the liquid storage part to the attachment separation device. Through the control method, the attachments can be separated from the gas treatment device preferentially, and secondary pollution of the liquid storage part to the filter layer can be reduced. The invention further provides another control method of the gas treatment device, that is, the humidity of gas to be treated can be adjusted by controlling the rotational speed of the filter layer.

Description

technical field [0001] The invention relates to the field of gas treatment, in particular to a gas treatment device and a control method for the device. Background technique [0002] Existing gas treatment devices, such as air purifiers, generally use filter screens to process air. After the filter screen has been used for a long time, impurities will accumulate on the filter screen, and the filter screen needs to be replaced, which is inconvenient for users to use. In order to solve the technical problem that the filter screen needs to be cleaned, Korean patent KR2010091734 discloses an air purifier, which uses a ring-shaped filter screen, which is driven by a motor to rotate, and one end of the ring-shaped filter screen is immersed in the water tank and placed in the water tank. There is a cleaning brush for cleaning the filter net, and the pollutants in the filter net are cleaned by the cleaning brush. In this way, the cleaning of the filter net is realized, and the filt...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when a gas treatment device such as an air purifier uses a liquid to process gas, a large number of pollutants attached to the filter layer enter into the liquid treated by the filter layer, thereby increasing the number of gas treatment devices. The more serious secondary pollution problem that occurs when dealing with gas
