Electrostatic dust collector for purifier

Abstract

The invention discloses an electrostatic dust removal device for a purifier, which comprises a fixed frame, a first fixed plate and a second fixed plate, the first fixed plate is located on the left side of the second fixed plate, and the fixed frame is fixed to the first fixed plate through an insulating fixed column head. On the left side of the plate and parallel to the first fixing plate, a number of through holes are provided, the through holes are arranged in parallel and spaced apart in a honeycomb shape, and the fixed frame is provided with a number of longitudinal cathode needle installation strips arranged in parallel and spaced apart, and A plurality of horizontal cathode needles are arranged at intervals along the length direction on each cathode needle installation bar, the right end of the cathode needle is located in the corresponding through hole, the fixed frame or the cathode needle is electrically connected to the negative voltage, the first fixed plate or the second The fixed plate is electrically connected with the positive voltage; the cathode needles are arranged with several polygonal metal sheets along the length direction. The invention can ionize air or cooking fume, generate a large amount of negative ions to form negative oxygen ions, has strong dust removal and sterilization effect, and is healthy and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to an electrostatic dust removal device suitable for purifiers in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places. Background technique [0002] The traditional electrostatic precipitator for air purification is designed according to the principle of corona discharge. It is generally composed of multiple electrode plates arranged in parallel. There is a high-voltage power supply between the electrode plates. When the dust in the air passes through the electric field, the corona effect is used to make it The dust particles in the air are charged, and when the charged dust particles pass through the electric field, they are deflected by force and are finally trapped on the dust collecting plate. But the corona range of electrostatic precipitators is usually limited to a few millimeters around the metal rod. When the air is ioniz...

AI Technical Summary

Problems solved by technology

The electrostatic precipitator designed according to this principle, first, the amount of negative ions produced is small, the effect of dust removal and sterilization is poor, and the air cannot be effectively purified at all, and the transportation distance of negative ions is short, basically only existing around the machine; second, excessive ozone is formed , damage the user's health
