Novel electrostatic dust removing structure

Abstract

The invention discloses a novel electrostatic dust removing structure. The novel electrostatic dust removing structure is characterized by comprising a dust pre-removing area, an electric agglomeration area and a fine particle capturing area communicated in sequence, wherein one end, far from the electric agglomeration area, of the dust pre-removing area is communicated with a smoke discharge outlet for filtering dust particles with medium and large particle sizes; the dust particles enter the electric agglomeration area after passing through the dust pre-removing area; the electric agglomeration area agglomerates the dust particles with small particle size as larger dust particles; and after the larger dust particles enter the fine particle capturing area, the fine particle capturing area captures the larger dust particles. The novel electrostatic dust removing structure is provided with the electric agglomeration area and the fine particle capturing area for filtering and capturing the dust particles with small particle size, so that the smoke filtering effect is improved, and the pollution of smoke on the environment is further prevented.

Description

technical field [0001] The invention relates to a structure of a dry electrostatic precipitator, more specifically, it relates to a structure of a dry electrostatic precipitator suitable for dust removal of coal-burning flue gas. Background technique [0002] At present, electrostatic precipitators are mainly used in the dust removal of coal-fired flue gas. Due to many advantages such as high dust removal efficiency and low equipment resistance (100~300Pa), nearly 90% of thermal power units in my country are equipped with electrostatic precipitators, and Almost all new large and medium units are equipped with electrostatic precipitators. However, the capture performance of fine particles with a particle size of micron and submicron is not good. [0003] For particulate matter in coal-fired flue gas, the total dust removal efficiency of the electrostatic precipitator can generally reach more than 99%. However, the capture performance of fine particles with a particle size of...
