Abstract

Abstract

Based on the analysis and research of the diffusion process of the flue gas in the coke oven head, this paper presented dust collecting hood with a grid mesh suction surface and a side suction structure to control the flue gas and analyzed through the method of computer simulation. The results showed that the suction form of the grid structure increased the effective suction area, optimized the distribution of the suction volume, and solved the problems of small effective suction section and unreasonable air volume distribution of the traditional dust collection hood. The suction structure at the front end of the dust collection hood could form a side suction effect for the smoke moving along the smoke guide plate to both sides, and that realized the collection of the smoke, and solved the problem of smoke discharged to both sides after impacting the smoke guide plate. The new dust collection hood structure could still effectively control the flue gas when the air volume of the fan was reduced by 30%, thus improving the dust collection efficiency.
