Method for improving air purifier insulation

Abstract

The invention relates to a method for improving air purifier insulation. According to the method, a shell installed at one side of a porcelain joint employs a sheet with insulation function to replacethe original metal plate so as to avoid direct contact of the porcelain joint with a metal shell. At the same time, a jetting method is employed to jet gas or liquid to the surface of the high-pressure porcelain joint to clean up the porcelain joint surface and remove the hidden conductive hazard of dust, so that the porcelain joint can always keep a high insulation state, conduction of current caused by porcelain joint dust accumulation and oil film condensation can be avoided, thereby guaranteeing good lampblack removal effect of a plasma range hood.

Description

technical field [0001] The invention relates to an air purification device, in particular to an insulation measure for a plasma air purification device, especially for the insulation of a plasma air purification device suitable for purifying air in places with a lot of dust and thick oil fumes. Background technique [0002] An existing plasma air purification device (ZL201010557216X) is really effective in removing dust and purifying air when it is first installed, but the effect is often reduced after less than three months or half a year of use, and even loses the functions of dust removal and air purification. In the end, most of these products are difficult to be widely used. The root cause of the poor air purification effect is that the polar plates of the two poles are conducted by the current, and the plates lose the electric field and lose the function of absorbing dust. At the same time, they also lose the function of purifying the air. The position where the plate ...

[0002] An existing plasma air purification device (ZL201010557216X) is really effective in removing dust and purifying air when it is first installed, but the effect is often reduced after less than three months or half a year of use, and even loses the functions of dust removal and air purification. In the end, most of these products are difficult to be widely used. The root cause of the poor air purification effect is that the polar plates of the two poles are conducted by the current, and the plates lose the electric field and lose the function of absorbing dust. At the same time, they also lose the function of purifying the air. The position where the plate is conducted by current is often at the bottle shank of the porcelain joint, where it is in direct contact with the metal plate of the collector. If there is a slight carelessness in the process of handling and installation, the porcelain joint and the metal plate are slightly damaged. The glaze film on the surface of the porcelain joint will have fine cracks, these cracks are invisible to the naked eye, but they will be easily broken down under a strong voltage, thus conducting the electrode plate of the emitter electrode and the collector electrode. Another reason is that on the surface of the high-voltage ceramic joint, a layer of dust or oil film will be deposited on the surface of the ceramic joint due to long-term use. This layer of dust or oil film will not conduct current under the voltage of 220V, but in Under the high voltage, this layer of dust or oil film becomes a conductor, and as a result, the air purification device loses the function of purifying the air.
