Abstract

The invention discloses a high frequency power supply for electric dust removal, which is composed of the following parts: an external three-phase incoming circuit, a three-phase fully-controlled rectifier bridge and driving circuit, an insulated gate transistor inverting and driving circuit, a direct current bus circuit, a temperature controller, a heater, a vibration and ash conveyance control circuit, a double-CPU (Central Processing Unit) high / low voltage integrated controller, a high frequency boosting transformer, a high frequency silicon stack rectification circuit and a secondary voltage / current and flashover feedback circuit. The high frequency power supply for electric dust removal, provided by the invention, is a high / low voltage integrated product, and compared with a line frequency power supply, the high frequency power supply is energy-saving and efficient, avoids the establishment of a ground control room and has a simpler, more compact and more reasonable structure.

Description

Technical field [0001] The invention relates to a high-frequency power supply for electric dust removal. Background technique [0002] The basic principle of the electrostatic precipitator (ESP) is that the dust-containing flue gas passes through a high-voltage electrostatic field, and the dust is collected in the electric field to achieve the purpose of flue gas purification. In order to establish a high-voltage electrostatic field, a high-voltage DC power supply is required. [0003] ESP is an important equipment in the field of environmental protection, mainly used in plasma discharge, dust removal, defogging, dehydration, air purification, high-efficiency dust removal and desulfurization, impurity separation, and multiple raw material recovery. [0004] The high-voltage electric field of ESP is equivalent to the parallel load of R and C, where C is the equivalent capacitance of the high-voltage electric field, generally several thousand to tens of thousands of PF, and R is a var...
