Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0023] like figure 1 As shown, in the airflow distribution structure 1 of the prior art, only an equalizer 10 is installed at the inlet, but no equalizer is installed at the outlet. Even if the incoming flow velocity is uniform, due to the resistance of the subsequent variable diameter Inhomogeneous characteristics will cause uneven speed before the diameter change.

[0024] like figure 2 As shown, in the airflow distribution structure 2 of the prior art, a flow equalizer 20 with equal pressure...

Abstract

The invention discloses an airflow distribution system applied to a wet electrostatic dust collector. The system comprises two flow equalization boards which are an inlet airflow equalization board arranged at an airflow inlet and an outlet airflow equalization board arranged at an outlet. The inlet airflow equalization board is a non-equal-pressure-difference flow equalizing board, and the outlet airflow equalization board is an equal-pressure-difference flow equalizing board. The system solves the problem that airflow in a dust collector is not distributed evenly. Compared with a conventional airflow uniform distribution plate, the energy-saving effect is better.

Description

technical field [0001] The invention relates to the field of gas purification, in particular to an air distribution system applied to a wet electrostatic precipitator. Background technique [0002] Wet electrostatic precipitator is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. It is an important equipment for dust emission reduction and ultra-clean emission in thermal power plants and industrial installations , It is also an important process equipment in some process systems. There are many factors that affect the dust removal efficiency of the wet electrostatic precipitator, such as the nozzle organization form, the polar plate layout form, the volt-ampere characteristics of the precipitator, the form of the air distribution plate, etc., among which the inlet and outlet air distribution plates directly affect the air flow distribution in the precipitator characteristics, which in turn affect the distri...
