High-frequency multiple high voltage pulse generating method, high-frequency multiple high voltage pulse power supply and electric precipitator

Abstract

The invention discloses a high-frequency multiple high voltage pulse generating method, a high-frequency multiple high voltage pulse power supply and an electric precipitator. According to the description, a master control unit controls high-frequency pulse power supply units needing to work at a certain moment to simultaneously generate direct-current high-voltage pulses according to setting; in work, the master control unit controls the high-frequency pulse power supply units needing to work at a certain moment to simultaneously generate the direct-current high-voltage pulses according to setting, and the direct-current high-voltage pulses are superposed at a total output end to form multiple high voltage pulses. The high-frequency multiple high voltage pulse power supply integrates various power supply modes, and direct-current power supply, intermittent pulse power supply and direct-current superposed-pulse power supply can be achieved. Pulse voltages are superposed on the basis of an effective direct-current corona voltage, step pulse supply is achieved, and the pulse leading edge time is short. High-ratio resistance dust can be effectively collected, back corona can be inhibited, the collecting efficiency of fine dust (PM2.5) can be improved, and the high-frequency multiple high voltage pulse power supply is a new-generation power supply of the electric precipitator.

Description

technical field [0001] The invention relates to a method for generating high-frequency multiple high-voltage pulses, a high-frequency multiple high-voltage pulse power supply and an electric precipitator. Background technique [0002] Electrostatic precipitator has a development history of more than 100 years. Because of its unique advantages such as high dust removal efficiency, wide application range, low operating cost, safety and reliability, convenient use and no secondary pollution, it is the first choice for industrial dust removal equipment, especially In thermal power generation, metallurgy, building materials and other industries. The national "Emission Standards of Air Pollutants for Thermal Power Plants" intends to increase the emission standards of smoke and dust from 50mg / m3 to 30mg / m3, and to 20mg / m3 in key areas. Faced with increasingly stringent emission standards, many electrostatic precipitators in service cannot meet the requirements and have to undergo ...

Problems solved by technology

However, the dust collector in the form of pulse power supply is relatively expensive, and the technical intellectual property rights are owned by foreign countries

In addition, the dust collector in the form of pulse power supply has a single function and can only complete pulse power supply.
