Description
Technical Field

Background
When sintering operation is carried out in the smelting industry, the igniter of the sintering machine needs negative pressure ignition. However, if the negative pressure value is high, the flame directly enters the ore layer, so that the ignition quality of the surface of the ore layer is poor, and meanwhile, the flame entering the ore layer burns insufficient carbon in the ore layer, so that the overall ignition quality is poor, and the rejection rate of the sintered ore is increased. Therefore, the ignition is needed to be gradual, so that high-quality sintered ore can be produced.
The negative pressure ignition of the sintering machine is realized through a sintering main exhaust dust removal system, and the system consists of an air box, a flap valve, a flue, an electric dust remover, an exhaust fan, a silencer, a desulfurization and denitrification system, a chimney and other parts. More than 90% of the pollutants generated in the sintering process are concentrated in the flue gas of the sintering flue, but the flue contains part of high-temperature flue gas besides the pollutants. At present, the part of high-temperature flue gas is discharged after being treated by dust removal, desulfurization, pin removal and the like. That is, the working environments of the electric dust collector, the exhaust fan, the silencer and the desulfurization and denitrification system are severe, and periodic maintenance and overhaul are required.
The magnitude of the negative pressure value of the sintering machine negative pressure ignition is usually regulated by the opening degree of a flap valve in the air draft dust removal system. In addition, when equipment such as the electrostatic precipitator of convulsions dust pelletizing system, air exhauster, muffler, SOx/NOx control system need be maintained, the flap valve needs to be closed completely, and is sealed well to the convenient maintenance. Therefore, the flap valve applied to the sintering machine exhaust dust removal system needs to be adjustable in opening degree and good in sealing when the flap valve is closed.
