Air purification device for sintering flue gas dust removal system

Abstract

The invention relates to an air purification device for a sintering flue gas dust removal system, which comprises a bracket and a shell, a filter box is arranged in a filter chamber, and the filter box is connected with the shell through a mounting frame; the shell is provided with an air inlet and an air outlet; a plurality of filter boxes are longitudinally arranged in the filter chamber along the airflow direction; the filter box is composed of a support, base cloth and filter cloth, the base cloth comprises latticed plain woven cloth or non-woven cloth, the filter cloth comprises non-woven cloth or a PTFE composite filter membrane, and the base cloth and the filter cloth are both connected with the support. Air can be further purified while dust is removed, the flue gas detection device is in electric signal connection with the control cabinet and the central control room, and the working state of the system is automatically monitored. The multi-stage large-air-volume efficient filter box is arranged and is installed and connected to the negative pressure end of the dust removal system and the ventilation pipeline, the dust collection rate can reach 99.99% after dust removal and efficient filtration, and the dust collection rate meets and is superior to the current national related environment-friendly emission standard.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification device used in a sintering flue gas dust removal system. Background technique [0002] Metallurgical plants will generate a lot of smoke and dust in the process of metal smelting. In particular, the current level of environmental protection equipment in the iron and steel industry is low, and the emission of pollutants remains high, which seriously affects the environment and restricts the improvement of the overall competitiveness of the iron and steel industry. Typical pollutants in the exhaust gas discharged by iron and steel enterprises mainly include dust, SO2, dioxin and other pollutants. About 70% of these pollutants are SO2, and about 90% of dioxin pollutants in the air come from steel sintering machines. . Therefore, the flue gas treatment of the sintering machine is one of the focuses of environmental protection work in the iron and steel i...
