Abstract

The invention discloses a photoelectrocatalysis air cleaning device having a turbulence air channel, which comprises a shell and an air-blowing mechanism arranged on the shell, wherein an air outlet is arranged on the shell; the air-blowing mechanism is connected to the air outlet through an arc-shaped air channel; a corona emitter electrode is arranged on the arc-shaped air channel; the corona emitter electrode and the inner wall of the arc-shaped air channel are respectively electrically connected to a power supply; a photoelectrocatalysis layer is coated on the inner wall of the arc-shaped air channel; and a dust-collecting cleaning wall is formed by the inner wall of the arc-shaped air channel under the condition of an electric field. The photoelectrocatalysis air cleaning device has reasonable space distribution, has large dust-collecting area, is high in cleaning efficiency, has wide cleaning scope, is low in air resistance and is small in energy consumption.

Description

technical field [0001] The patent of the present invention relates to a photocatalytic air purification device, in particular to a new generation of air purifier with a photocatalytic air purification device with a turbulent air duct, which is suitable for household, automobile, medical treatment, public health and other fields. Background technique [0002] At present, the existing purifiers mainly have the following methods: adsorption type, electrostatic type, etc. The above purification methods usually adopt the method that the air supply mechanism and the dust collection and purification components are independent modules and combined, the air supply mechanism Cross-flow, axial-flow, and cross-flow fans can be used to bring the polluted air through the dust collection assembly, and the dust collection and purification assembly intercepts the pollutants in the air, so the air is purified. [0003] Since the dust collection and purification components have a certain wind ...

AI Technical Summary

Problems solved by technology

[0003] Since the dust collection and purification components have a certain wind resistance, the higher the purification efficiency is, the greater the wind resistance will be. Therefore, in order to obtain greater purification efficiency, the power of the motor must be increased to obtain a relatively high purification efficiency. Increased, the wind resistance increases and also produces a relatively large noise

For air purifiers using electrostatic dust collection technology, if the wind speed is too high, it is easy to generate secondary dust and reduce the purification efficiency

[0004] Regardless of whether a cross-flow fan, an axial-flow fan or a cross-flow fan is used, the air duct takes up a lot of space, and the purifier products composed of the air duct and the dust collection and purification module are generally relatively large in size and low in efficiency, which also affects the purifier. The technical development of the product has brought constraints

[0005] However, due to the diversity of air pollution types and the complexity of air components, the common pollution types in the air such as PM10, microbial virus bacteria, odor, TVOC and other pollutants are known, and traditional purification technologies can usually only target one of them. A variety of pollutants, unable to achieve comprehensive purification of multiple pollutants at the same time
