Dust collecting module and electrostatic air cleaning apparatus

Abstract

The invention provides a dust collecting module. The dust collecting module (200) is used to collect electric particles in gas, and at least comprises conductive thin films and insulated panels (3) which are arranged alternately, so that channels (4) allowing air to pass are formed by the insulated panels (3) and adjacent conductive thin films. The invention also provides an electrostatic air cleaning apparatus, and the apparatus comprises the dust collecting module (200). The provided dust collecting module and the electrostatic air cleaning apparatus help to substantially improve the air cleaning efficiency; especially the dust collecting module generates little ozone or none, is capable of fully eliminating flip-flop noise caused by breakdown of air, and almost does not have overflowing of positive ions; and the manufacturing is convenient and the cost is relatively low.

Description

technical field [0001] The invention relates to electrostatic dust removal technology, in particular to a dust collection module and an electrostatic air purification device using the dust collection module. Background technique [0002] With the advancement of industrialization, more and more serious air pollution is threatening the physical and mental health of the people. Therefore, the market urgently needs air purifiers that can effectively remove particulate matter. At present, the commonly used air purifiers are mostly filter purifiers and electrostatic precipitator purifiers. [0003] The filter type purifier uses a fan to draw air into the purifier, and then filters the air through the built-in filter. This filter-type air purifier generally uses a HEPA filter to absorb particulate matter in the air. However, after this kind of purifier is used for a long time, the filter screen will gather some dust, and the filter screen will become moldy and hairy in a humid en...

AI Technical Summary

Problems solved by technology

[0005] 1) The cathode for adsorbing particulate matter uses a metal plate, which is relatively high in cost, complicated in production process, and relatively heavy;

[0006] 2) Because the metal plates are exposed in the air, the air between the two metal plates is easily broken down to generate ozone, and each breakdown will be accompanied by "crackling" noise, which will interfere with the environment; if the air humidity increase, it is easy to produce corona phenomenon, and more ozone will be produced

[0007] 3) In order to minimize the probability of air breakdown between metal plates, the distance between adjacent metal plates is generally increased (generally greater than 5mm) or the potential difference is reduced, which results in weaker electric field strength and metal The plate cannot absorb all charged particles at one time, and the purification efficiency at one time is very low

[0008] 4) After the metal plate absorbs dust particles, it is difficult to clean the metal plate because the combination of dust and metal is tight
