An electric bag combination shunt three-state dust collector

Abstract

The present invention relates to A combination of electric bags Split three-state dust collector, including electrostatic precipitator, bag dust collector, air inlet pipe and air outlet pipe, the air inlet pipe is connected with the electrostatic precipitator, and the electrostatic precipitator is connected with the bag dust collector; Box body, the box body of the electrostatic precipitator has an outlet of the electrostatic precipitator, and the air outlet of the electrostatic precipitator is provided with an outlet valve of the electrostatic precipitator; The clean air chamber of the bag filter has an air outlet of the bag filter, and the air outlet of the bag filter is provided with a bag filter outlet valve; the air outlet of the electrostatic precipitator and the air outlet of the bag filter are connected to the air outlet pipe at the same time Pass. The invention combines the advantages of the electric and bag dust collectors, can operate in different regions, switch between each other, and work at the same time, fully exerts the characteristics of the electric and bag dust collectors, protects each equipment, and meets the requirements of environmental protection.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an electric bag combination split flow three-state dust collector. Background technique [0002] The dust removal mechanism of the electrostatic precipitator is based on the fact that the dust is charged in a high-voltage electric field, and then is trapped on the dust collecting plate to achieve the purpose of dust and gas separation. Fine dust is difficult to be collected by electrostatic precipitators due to its small particle size, light weight, low charge capacity, and "secondary dust" caused by vibration cleaning. It can be said that the dust removal mechanism of the electrostatic precipitator itself limits the further improvement of its dust removal efficiency. The conventional electrostatic precipitator should reach 20mg / Nm 3 This new emission standard is very difficult or uneconomical. [0003] The bag filter achieves the purpose of dust removal through the mec...

Problems solved by technology

In order to avoid a sudden rise in the temperature of the flue gas in the dust removal system, or when the four tubes of the boiler gas saving, reheater, superheater, and water wall leak or burst, especially when the boiler is frequently shut down, the The soot generated during ignition will have a negative impact on the use of the filter bag. A dust collector that can meet the requirements of the bag filter and has an electrostatic precipitator that can adapt to high temperature, high humidity, and oily smoke is used to solve the above problems. The existing problems of the known dust collector structure are very urgent both technically and economically.
