The pollutant emission of the coke oven not only comprises coal dust and coke dust, but also contains toxic gas, which is always the field of important supervision of environmental protection departments. Although dust collection and treatment systems such as a coal-charging dust-removing system, a coke-discharging dust-removing system and the like have been developed for many years, the dust collection and treatment systems still cannot avoid the blow-by of a coke oven door, the inexact coal-charging hole of the oven top, the temporary discharge of a riser and the sporadic discharge of unorganized pollutants generated during the opening and closing of the oven door.
The most practical and effective solution for treating the scattered smoke dust of the coke oven is to seal the coke oven integrally by a large cover body, and the discharged high-temperature gas and smoke dust can be converged towards the top of the cover body, so that the coke oven can be collected and treated in a concentrated way. Therefore, how to design a fully-closed coke oven smoke dust collecting system which is used in a fully-closed coke oven system and is used for collecting the scattered smoke dust of a coke oven in a concentrated manner and does not influence production vehicles and oven body equipment becomes an important object of the invention.
