Abstract

The invention discloses the use of a high-frequency power supply in an electrostatic fabric filter for solving the problems of low dust collection efficiency and the like of the power-frequency power supply of the prior electrostatic fabric filter. The electric field dust charge strengthening effect of the high-frequency power supply is used to provide adequate electric field charge, allow dust on the surface of a filter bag to distribute and attach orderly and loosely, and ensure high gap rate. Thus, dust collection efficiency is improved greatly and the high-frequency power supply is an ideal rich-energy power supply for the electrostatic fabric filter.

Description

Technical field: [0001] The invention relates to the use of high-frequency power supply, in particular to the application in electric bag compound dust collector. Background technique: [0002] Such a high-frequency power supply is disclosed on the market. Its structural characteristics are: it is composed of a three-phase rectifier bridge, a full-bridge series-parallel resonant power converter, a main control system, a high-frequency and high-voltage silicon rectifier transformer, and a detection and feedback system. The three-phase rectifier The bridge is electrically connected to the full-bridge series-parallel resonant power converter, the full-bridge series-parallel resonant power converter is electrically connected to the main control system with a high-frequency high-voltage silicon rectifier transformer, and the high-frequency high-voltage silicon rectifier transformer is electrically connected to the detection and feedback system. The feedback system is electrically...
