Description
Technical Field
The invention relates to the technical field of coke oven smoke dust treatment, in particular to a tamping coke oven machine side coal charging smoke dust anti-dissipation system and a tamping coke oven machine side coal charging smoke dust anti-dissipation method.
Background
The tamping coke oven is one of mechanical chamber type coking processes, can increase the proportion of weak caking coal and efficiently utilize coking coal resources compared with a top-loading coke oven, is a preferred process technology suitable for the resource status of the coking coal 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 tamping coke oven has the characteristics of large smoke amount, high water content, large viscosity and the like, and the smoke trapping difficulty is large due to the fact that 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 is seriously escaped in the coal charging process of the tamping 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 stamp-charging coke oven, a great deal of energy is invested by vast environmental protection workers and related scientific and 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 on the top of the oven, a purification process combining the collection and combustion of the smoke on the top of the oven with a dry ground dust removal station, a treatment process combining the collection and combustion of the smoke on the top of the oven with a U-shaped pipe smoke guide device and the like. 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.
