Description
Technical Field
The utility model relates to an industrial waste gas purification handles the field, especially relates to a coke oven coal-charging furnace end cigarette stove top leads cigarette car booster unit.
Background
The tamping coke oven comprises a coke oven body, a machine side coke pushing car, a machine side coal charging car, a coke side coke guide, a coke tank car and the like. The traditional coke oven dust removal system consists of a coke oven coal charging dust removal system and a coke discharging dust removal system. The coal charging and dust removing system is responsible for the flue gas purification treatment when the coal charging car charges coal, the coke discharging and dust removing system is responsible for the flue gas purification treatment when coke is discharged, and the dust removal of the coke pusher is mostly purified by the vehicle-mounted dust remover. In recent years, along with the generation of a 6.25m stamp-charging coke oven and a 6.78m stamp-charging coke oven, the height of an oven body is continuously increased, and the dust removal effect of a smoke dust removal system of a coal charging oven head of the coke oven is poor due to irregular operation of the coke oven, which is particularly shown in the way that a large amount of yellow smoke is generated above a smoke guide vehicle when the coke oven is charged with coal.
The dust removal system fan of the coke oven coal charging furnace end smoke can not suck out the smoke of the coke oven coal charging furnace end, and the reason is that: 1) the smoke interface valve of the coal charging furnace end in the coke oven coal charging furnace end smoke dust removal system deforms at high temperature, and cannot be completely sealed and has a large gap when being butted with a smoke guide vehicle, so that a large amount of ambient air is sucked by a fan of the coke oven coal charging furnace end smoke dust removal system, and the coal charging dust removal effect is poor; 2) the smoke guide vehicle can not be aligned with smoke interface valves of certain coal charging furnace ends, and when the hole is operated for charging coal, the dust removal system fails; 3) some coke ovens lack an interlocking system during operation and are completely operated manually by operators of smoke guide cars, so that the operation of a dust removal system is delayed;
meanwhile, the emission standard of pollutants for coking chemical industry (GB16171-2012) issued in 2012 and increasingly strict local emission standards issued in various places mainly in Hebei, Shanxi and Shandong require particulate matter emission of a coke oven dust removal system<10mg/Nm3The traditional coal-charging furnace end smoke dust removal device and the traditional coal-charging furnace end smoke dust removal process can not meet the smoke dust removal and purification requirements of a large tamping coke oven, so that a dust removal assisting facility is added on a tamping coke oven smoke guide vehicle by combining an operation system of the tamping coke oven, and the improvement of a coke oven end smoke dust removal system is a problem to be solved urgently in coke oven dust removal at present.
