Abstract

The invention provides a static hop-pocket mixed dust removal device and a control method thereof, belonging to the technical field of flue gas purification and dust removal. The device of the invention comprises a plurality of static hop-pocket mixed dust chambers and is structurally characterized in that the flue gas inlet of the static hop-pocket mixed dust chamber is connected with an inlet main flue by an outlet sub flue provided with a flue gas stop valve. The flue gas outlet of the static hop-pocket mixed dust chamber is connected with an outlet main flue by an outlet sub flue provided with the flue gas stop valve, and a flue gas purification chamber at the top part of the static hoop-pocket mixed dust chamber is connected with the outlet main flue by an upper outlet sub flue provided with the flue gas pipe valve. The inlet main flue and the outlet main flue are respectively provided with a flue gas interconnection valve on the main flues arranged between two adjacent front inlet sub flues and between two adjacent rear outlet sub flues. The invention can realize flexible conversion of multiple operation modes, and improves dust removal efficiency of the whole dust removal system.

Description

technical field [0001] The invention relates to the technical field of flue gas purification and dust removal, in particular to an electrostatic bag mixing dust removal device and a control method thereof. Background technique [0002] In industrial production, such as thermal power generation, cement production, and metallurgical industries, gases containing a large amount of dust are often produced. Before these large quantities of gases carrying particulate matter are discharged into the atmosphere, they must be purified by dust removal equipment. In the prior art, dust removal devices for a large amount of dusty gas include traditional electrostatic precipitators and pulse-jet cloth bag dust collectors. To obtain higher dust removal efficiency, dust collectors with different principles can be combined in a special way to jointly remove the particulate matter in the dusty airflow to achieve the highest possible dust removal efficiency. However, in the prior art, it is o...
