Description

Technical Field

[0001] The utility model relates to the technical field of loading stations, in particular to a dust removal device for a coke fast loading station. Background Art

[0002] Coke is a solid product of high-temperature dry distillation. Its main component is carbon. It has cracks and irregular pore structures or pore porous bodies. It has many cracks, high porosity, and low strength and crushing strength. Based on the properties of coke itself, when the loading station is loading coke, a lot of dust will be generated in the loading area. The operator cannot see the operating status of the loading chute, which affects the loading. At the same time, the high dust concentration also increases the safety risk of the working environment and affects the health of the operators. Because coke needs to strictly control the moisture content, the fluctuation of the moisture content in the coke will cause inaccurate coke metering, thereby affecting the quality of the coke and causing fluctuations in the furnace condition. Therefore, during the coke loading process, it is impossible to suppress the generation of dust through conventional means such as water spraying or dry fog dust suppression. Utility Model Content
