Micro-electric-field electrocoagulation short-process bag type dust collector

Abstract

The invention is applicable to the technical field of flue gas purification equipment. The invention provides a micro-electric-field electrocoagulation short-process bag type dust collector. The device comprises a dust filtering assembly, a dust collecting assembly and an exhausting assembly. The dust filtering assembly comprises a filtering box, a first buffer plate, a second buffer plate and a dust removing cloth bag. The dust collecting assembly comprises a dust collecting hopper, an electromagnetic valve, a pressure sensor and a controller. The exhaust assembly comprises an exhaust pipe and a pulse valve. Through arranging the filter box with the first buffer plate and the second buffer plate, when gas is introduced, the gas is buffered, and airflow is more uniform. Through arranging adust collecting hopper with a pressure sensor and an electromagnetic valve, the controller controls the electromagnetic valve to be opened according to the pressure value detected by the pressure sensor when the pressure value is higher than a preset pressure value, dust removal can be conducted on the cloth bag through the pulse valve by arranging the exhaust pipe with the pulse valve, and the bag type dust collector has the advantages of being high in dust collection efficiency and convenient to clean the cloth bag.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification equipment, in particular to a micro-electric field electrocoagulation and short-flow bag filter. Background technique [0002] The flue gas of industrial furnaces in various fields is characterized by fine dust particles accounting for a certain percentage, and containing fine particles of PM2.5 and PM1 levels at high temperatures. Usually use electrostatic precipitator and bag filter for purification. [0003] The electrostatic precipitator ionizes the gas through a high-voltage electric field so that the fine particles flowing through the electric field are charged and collected under the action of Coulomb force to achieve the purpose of dust removal. Ultra-clean emission; the bag filter has extremely low air permeability and high operating resistance due to the participation of fine particles in forming a dust layer, resulting in high operating costs. To achieve ultra-low emissio...

Problems solved by technology

[0003] The electrostatic precipitator ionizes the gas through a high-voltage electric field so that the fine particles flowing through the electric field are charged and collected under the action of Coulomb force to achieve the purpose of dust removal. Ultra-clean emission; the dust layer is formed due to the participation of fine particles in the bag filter, the air permeability is extremely low, and the running resistance is large, resulting in high operating costs. To achieve ultra-low emission levels, operating costs need to be increased, which will increase the burden on enterprises

When the national emission standards become more and more stringent, neither the conventional electrostatic precipitator nor the bag filter can meet the requirements
