Description

Electrostatic dust removal pipeline

Technical Field

The utility model relates to an electrostatic precipitator pipeline.

Background

In the process of firing perforated bricks, standard bricks and the like, a large amount of firing waste gas is generated, and the waste gas contains more pollutants such as particle dust, sulfur dioxide and the like and needs to be collected and treated through a pipeline so as to reach the emission standard.

In the prior art, the burning waste gas is generally directly conveyed to an absorption tower through a waste gas pipeline, and is discharged after absorbing sulfur dioxide. And the granule dust wherein then partly is washed by the absorption liquid, and the part adsorbs on absorption tower inner wall or filler, and the subtotal still remains and discharges in the waste gas.

Since a large amount of sulfur dioxide is adsorbed by the granular dust, the granular dust adsorbed by the absorption tower or the filler can form a strong corrosion central point, which is extremely unfavorable for the service life of the equipment, so that the pretreatment of the firing waste gas is necessary to reduce the granular dust in the firing waste gas.
