Bag deduster prepared by reconstructing electric deduster

Abstract

The invention relates to a bag deduster prepared by reconstructing an electric deduster. The bag deduster comprises an electric deduster, an ash bucket (2), a shell (1), and an inlet horn, and an outlet horn. An air purifying box (3), which is composed of a dust removal system, a lower porous board (4), and an upper inspection rack (5), is installed in the upper part of the shell (1). The bag deduster is characterized in that an air duct (11) is arranged on two sides of the shell (1); the upper part of the air duct (11) is connected to the air purifying box (3), the lower part stretches into the shell (1) through a connection pipe (14); a guide plate (16) is obliquely arranged in the air duct (11), the air duct below the guide plate (16) is a lower air duct (12), which is communicated withthe inlet horn (17), the air duct above the guide plate (16) is an upper air duct (13), which is communicated with the outlet horn (18); and the cross section of the inlet of the shell (1) is provided with a partition plate (19). A plug-in air duct technology is adopted, the construction amount and deduster downtime are both reduced, the reconstruction period is shortened, and the construction efficiency and air quality are both improved.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to a bag-type dust collector modified by utilizing an electric dust collector. Background technique [0002] During the rapping process of the electrostatic precipitator, the dust will generate secondary dust, causing the emission to exceed the standard. This is determined by the principle of the electrostatic precipitator and cannot be avoided. With the improvement of national environmental protection standards, the electrostatic precipitator should reach 20mg / Nm 3 Below, even 10mg / Nm 3 The following environmental protection emission standards, so almost all of the active electrostatic precipitators need to be modified. To modify the current electrostatic precipitator, the entire system must be shut down. If the cycle is too long, it will affect the production and increase the production cost. Therefore, it is necessary to complete the standard transformation of the activ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of long construction period and difficulty in installing an air duct in the existing electric bag filter, and provides a bag filter modified by using an electric dust collector. By using an external air duct, it can The overall hoisting is completed without stopping the machine, which greatly shortens the renovation period. At the same time, the original inlet and outlet horns and internal pipe supports are not removed, which reduces the workload and ensures the quality of the construction.
