Electrostatic dust catcher having secondary dust removal

Abstract

The invention discloses an electrostatic dust catcher having secondary dust removal. The electrostatic dust catcher comprises a dust catcher comprises a dust catcher body, wherein a dust inlet and anexhaust hole are respectively formed in two sides of the dust catcher body, a plurality of dust hoppers are arranged at the bottom of the dust catcher body and are fixedly connected with the dust catcher body by support rods, a first chamber, a second chamber and the third chamber are sequentially arranged in the dust catcher body from left to right, an airflow distribution plate and a vibrator are arranged in the first chamber, a first filtering chamber, a second filtering chamber and a third filtering chamber are sequentially arranged in the second cavity from left to right, stainless steelnets are arranged at the bottoms of the first filtering chamber, the second filtering chamber and the third filtering chamber, and an inlet is formed between a position, far away from one side of thesecond filtering chamber, of an upper part of the first filtering chamber and the first chamber. The electrostatic dust catcher has the beneficial effect that dust processing is more thorough, dust collection is facilitated, and environment pollution is prevented.

Description

technical field [0001] The invention relates to the technical field of dust collectors, in particular to an electrostatic dust collector with secondary dust removal. Background technique [0002] Electrostatic dust removal is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through the high-voltage electrostatic field, and the dust particles and negative ions are combined with negative charges, and tend to discharge and deposit on the surface of the anode. It is used to purify gas or recover useful dust particles in metallurgical and chemical industries. A dust collection method that uses an electrostatic field to ionize the gas so that the dust particles are charged and adsorbed to the electrode. In the strong electric field, air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of rushing to the positive electrode, so that the dust particles are negatively c...

AI Technical Summary

Problems solved by technology

However, with the increasing environmental protection requirements of the country, the emission requirements for coal-fired boiler flue gas are becoming increasingly strict. However, when dust is removed in the dust collector, dust will fly again due to vibration and dust removal, making the dust removal not thorough enough. At the same time, the remaining particle dust cannot be fully collected, so that there will still be some waste dust remaining in the air that cannot be completely processed
