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 pointed out that for those of ordinary skill in the art, a number of modifications and improvements can be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0023] Such as figure 1 As shown, in the prior art airflow distribution structure 1, only a flow-sharing plate 10 is installed at the inlet, but no flow-sharing plate is installed at the outlet. Even if the incoming flow velocity is uniform, it is due to the resistance of the subsequent reducing part. The characteristics are not uniform, which will lead to uneven speed before the diameter reduction part.

[0024] Such as figure 2 As shown, in the prior art air distribution ...

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 airflow 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 humid gas. It is an important equipment for dust reduction and ultra-clean emission of 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 pole line arrangement form, the volt-ampere characteristics of the precipitator, the air distribution plate form, etc. The inlet and outlet air distribution plates directly affect the air distribution in the precipitator The characteristics, in turn, affect the airflow velocity field distribution in...
