Technical Field

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, wherein the coal charging dust removal system is responsible for the flue gas purification treatment when a coal charging car charges coal, the coke discharging dust removal system is responsible for the flue gas purification treatment on a coke side when coke is discharged, and the dust removal of a coke pusher is mostly purified by an on-board dust remover. In recent years, with the generation of 6.25m stamp-charging coke ovens and 6.78m stamp-charging coke ovens, the issuance of emission standards of pollutants for coking chemical industry (GB16171-2012) issued in 2012 and the issuance of increasingly strict emission standards in places such as Hebei, Shanxi and Shandong, the particulate matter emission of coke oven dust removal systems is required<10mg/Nm³The traditional coke pusher vehicle-mounted dust removal process cannot meet the smoke dust removal and purification requirements of a large tamping coke oven, so that the problem of urgent need to be solved in the existing coke oven production is to study the side dust removal of the tamping coke oven machine by combining the operation system of the tamping coke oven.

The research on the operation system of the coke pusher and the coal charging car finds that when the coke pusher and the coal charging car are operated, a part of operation time is overlapped; according to the research on the smoke dust escaping from the oven door when the coke pusher on the coke oven side is operated, the smoke dust contains a large amount of dust and other particulate matters, and also contains tar and a part of water vapor, and the smoke gas components are very similar to those of the smoke gas components of the oven end smoke of the coal charging car, so that the research on the two-in-one dust removal system and the process for the coal charging and the coke pushing of the coke oven side are an optimal way for solving the problems of coke pushing and dust removal of the tamping coke oven, and are economic and environment-friendly.
