Electromagnetic dust remover and smoke purification system

Abstract

The invention discloses an electromagnetic precipitator, comprising: a charging device; a magnetic field module arranged in the downwind direction of the charging device, the magnetic field module comprising two oppositely arranged magnetic poles; a magnetic field located in the magnetic field formed by the magnetic field module A plurality of dust collecting plates inside, and the plate surface of the dust collecting plates is parallel to the airflow direction and the magnetic field direction of the magnetic field; wherein, the voltage of the charging device is adjustable, and / or the magnetic field module The strength of the magnetic field is adjustable, and / or the distance between two adjacent dust collecting plates is adjustable. Since at least one of the voltage of the charging device, the magnetic field strength of the magnetic field module and the distance between two adjacent dust collecting plates can be adjusted, by adjusting the above parameters, most of the dust particles can reach the dust collecting plate and be captured , which can ensure the dust removal effect of the equipment under different working conditions. The invention also discloses a flue gas purification system using the electromagnetic dust collector.

Description

technical field [0001] The invention relates to the technical field of dust removal and purification, in particular to an electromagnetic dust collector and a flue gas purification system. Background technique [0002] With the continuous aggravation of air pollution, air treatment has become a consensus among people. Purification and dust removal of various gases discharged into the atmosphere is an effective means of air purification. Therefore, purification and dust removal technology has been widely used in air pollution control. more and more widely applied. [0003] Taking the treatment of flue gas emissions from power plants as an example, the current wet desulfurization process is the most mature technology for flue gas desulfurization in thermal power plants in my country. However, the flue gas after wet desulfurization still contains fine particles and aerosols. Especially for PM2.5 and other particles, wet desulfurization can hardly achieve any treatment effect. ...

AI Technical Summary

Problems solved by technology

[0005] However, due to the constant electric field strength of the current wet electrostatic precipitator, it has relatively strict requirements on the concentration of the inlet flue gas and the wind speed of the flue gas. In order to reduce the wind speed, it is necessary to increase the volume of the equipment to increase the cross-sectional area of ​​the flow, which will cause the overall equipment to be too large and the operating cost to be high
