Dust removal system for removing and purifying sintering flue gas pollutants

Abstract

The invention relates to a dust removal system for removing and purifying sintering flue gas pollutants, which comprises a quench tower, a first dust remover, an absorption tower and a second dust remover which are sequentially connected, the upper part of the absorption tower is provided with an active coke purification filter layer, the middle part of the absorption tower is provided with an active coke purification filter plate, and the lower part of the absorption tower is provided with a desulfurizer storage device, a Venturi tube and a water spray nozzle; the second dust remover is connected with an air purification device; the air purification device is connected with an exhaust chimney through a fan; the air purification device comprises a shell and a filter chamber, a plurality of detachable filter boxes are longitudinally arranged in the filter chamber in the airflow direction, and each filter box is composed of a support, base cloth and filter cloth. The control cabinet is provided with a PLC (Programmable Logic Controller) and a pulse controller; and the PLC is electrically connected with the pulse controller and the blowing device. According to the sintering flue gas treatment device, air is further purified while sintering flue gas is treated; by adopting the sinter plate filter element, the ash removal effect is improved, and the service life is long; and online detection and real-time data recording are carried out, so that standard emission is ensured.

Description

technical field [0001] The invention relates to the technical field of sintering flue gas treatment, in particular to a dust removal system for removing and purifying sintering flue gas pollutants in the metallurgical industry. 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 environm...
