The tamping coke oven is one of mechanized chamber type coking processes, compared with a top-loading coke oven, the tamping coke oven can increase the proportion of weak caking coal and efficiently utilize coking coal resources, is a preferred process technology suitable for the situation of the coking coal resources in China, and is widely applied to China at present.
However, compared with a top-charging coke oven, the smoke generated in the coal charging process of the stamp-charging coke oven has the characteristics of large smoke amount, high water content, large viscosity and the like, and the smoke is difficult to capture because a side-charging process is adopted in the coal charging process and the contact surface of a carbonization chamber and the atmosphere is large in the coal charging process, so that the smoke escapes seriously in the coal charging process of the stamp-charging coke oven, and the atmospheric environment is seriously polluted.
For the collection and treatment of the smoke generated in the coal charging process of the tamping coke oven, a great deal of energy is invested by a great number of environmental protection workers and related technical personnel, and various treatment processes and technologies are also applied, such as a wet dust removal purification process after the collection and combustion of the smoke at the top of the oven, a purification process combining the collection and combustion of the smoke at the top of the oven with a dry ground dust removal station, a treatment process combining the collection and combustion of the smoke with a furnace end smoke collection ground station and the like by utilizing a U-shaped pipe smoke guide device at the top of the oven to guide the smoke into a coal gas collection system. The coal-charging smoke dust treatment processes have a certain control and purification effect on the coal-charging smoke dust of the tamping coke oven, but the smoke dust escaping from the open oven door at the side of the machine in the coal charging process cannot be effectively controlled and collected, so that the smoke dust escaping from the tamping coke oven in the coal charging process is still serious, the pollution to the environment is still continuous, great environmental protection pressure is brought to production enterprises, and the application and popularization of the tamping coking technology are limited to a certain extent.
Generally, when a tamping coke oven is used for charging coal, smoke escaping from an open oven door at the side of the oven is controlled by arranging a sealing oven door frame at the oven door at the side of the oven to strengthen the sealing of the oven door and arranging a smoke collecting cover above the sealing frame to collect the smoke escaping from the oven opening. However, in actual production, the amount of coal-charging smoke dust escaping from the furnace mouth is large due to various reasons, the sealing effect of the sealing furnace door frame is limited, the smoke dust collecting cover above can only collect part of the escaping smoke dust, and most of the smoke dust is still not effectively controlled.
