Problems solved by technology

In order to make up for the loss in this period, it is necessary to increase the supply voltage value, but due to the severe nonlinearity of the load curve 3, the load curve 3 will produce a large peak, and the high-density free electrons that form the current peak cannot be used to effectively charge the passing dust particles in a short time, so a large number of remaining electrons fly directly from the corona pole line 12 to the dust collecting plate 13, formin

Abstract

The DC electrostatic dedusting process includes the following successive steps: regulating the input power source into industrial frequency power source, stepping up the industrial frequency voltage with the industrial frequency step-up transformer, rectifying in the industrial frequency high voltage rectifier, high voltage filtering in the high voltage filter, and applying the high voltage DC voltage to the dust collecting plate via the high voltage terminals. The DC electrostatic deduster has high frequency inversing link comprising low voltage rectifier, low frequency filter, high frequency inverter, high frequency step-up transformer, high frequency high voltage rectifier and high frequency high voltage filter connected successively. The present invention has obvious power and steel saving effect.

Description

technical field [0001] The invention relates to an electrostatic precipitator and method applied in the technical field of electrostatic precipitator for environmental protection, in particular to a DC electrostatic precipitator and a dust removal method. Background technique [0002] At present, in the field of electrostatic dust removal technology, the "best electric spark rate dust removal method" is widely used at home and abroad. This dust removal method can be seen in the book "dust collector", published by China Architecture Press. It is pointed out in the book that in 1950, American scholar White proposed the concept of the optimal degree of electric spark in electrostatic precipitator, that is, when the power supply increases to a certain level, the number of electric field discharges increases, and the dust removal efficiency has a maximum value. Due to the frequent high-voltage ignition process, it is required that the power supply can only use power frequency rec...
