Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] As shown in the accompanying drawings, the main body 1 of the large particle collision dust-reducing device at the air inlet of the boiler electrostatic precipitator disclosed by the present invention is a square cone structure composed of 4 triangular collision plates, the head of the square cone is closed, and the rear part is open. The angle is set according to the square cone angle of the air inlet of the electrostatic precipitator, and the support device 2 is fixedly connected with the air inlet of the electrostatic precipitator on the cone. The installation is determined according to the size of the air inlet of the electrostatic precipitator and related dimensions. distance.

[0018] When the large particle dust enters the inlet of the electrostatic precipitator, it first touches the large particle collision device of the square cone interface, ...

Abstract

The invention discloses a large particle impact dust falling device for an air inlet of an electrostatic precipitator of a boiler, aiming at solving the problem that the air inlet of the existing electrostatic precipitator is not provided with a dust falling device for blocking large particle dust. The main body of the device is a rectangular conical structure consisting of impact plates, wherein a support device is arranged on the main body, and is fixedly connected with the air inlet of the electrostatic precipitator. The device has the advantages of simple structure, easiness for manufacture and assembly, long service life, wide applicability and remarkable effect of large particle dust removal.

Description

technical field [0001] The invention relates to a dust reducing device for an air inlet of an electric precipitator for a boiler. Background technique [0002] Thermal power plants and boilers generally use electric precipitators for dust removal, especially for large thermal power boilers. During the use of electric precipitators, due to the large air volume and the presence of large particles in the dust particles after the boiler fire burns, In recent years, it has been found that the electrode plate of electrostatic precipitator and electric field is seriously damaged. Since the electric field is the closest to the air inlet, when the large particles at the air inlet pass through the airflow uniform distribution device, the airflow uniform distribution will be severely worn. When the large particle dust cannot be effectively organized, the large particle dust directly enters the electric field, which will cause serious wear and tear on the dust collection plate and the p...
