Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that conventional electrostatic precipitators in the prior art have low efficiency in collecting fine particles, and the uncaptured fine particles escape into the main air flow, reducing the dust removal efficiency of the dust collector. Running resistance is so large that the generator set cannot run at full load, etc., and an electric bag filter is provided

Abstract

The invention discloses an electric bag type dust collector, and relates to the technical field of dust collector equipment. In order to solve the problems that an electric dust collector is low in fine particle trapping efficiency and cannot meet the emission standard, the electric bag composite dust collector is characterized in that a pulse bag type dust collector is connected in series behind a first electric field of the electric dust collector, equivalently, a corona electrode device is reserved in a second electric field of the electric dust collector; and a plate type dust collecting electrode is replaced by a bag type dust collecting electrode with the electrode dust collecting and airflow filtering dust collecting effects, and the airflow filtering device is provided with an air inducing device and a compartment dust cleaning device. When flue gas enters the first electric field of the electric bag dust collector, 90% of dust is removed. And when the flue gas carrying the rest 10% of dust enters the second electric field, the bag type dust collecting electrode with the electrode dust collecting function and the airflow filtering dust collecting function almost collects all the rest 10% of dust, and the flue gas meeting the emission standard is discharged from an air outlet of the second electric field from a second electrode. The electric bag type dust collector is used for coal-fired boilers, steelmaking furnaces and industrial kilns.

Description

technical field [0001] The invention relates to the technical field of dust collector equipment, in particular to an electric bag dust collector. Background technique [0002] At present, the conventional electrostatic precipitator has the characteristics of easy large-scale, low running resistance, wide application range, etc., and the large particle dust has good chargeability and fast driving speed. The first electric field can remove 90% of the dust, but due to the mechanism of the electrostatic precipitator It is determined that most of the remaining 10% of the dust is fine particle dust, which has poor charging performance, slow driving speed, and is easy to escape with the main airflow. Replaced by bag filter or electric bag filter. [0003] At present, the electric bag composite dust collector is widely used, which is composed of a series of bag dust collectors after the first electric field of the conventional electric dust collector. Although the two-stage dust re...
