Optimization Design of the Structure of the Coke Oven Hood for Collecting Smoke and Dust
In order to improve the suction energy efficiency of the coke oven head smoke dust cover,the characteristics of the coke oven head smoke emission process were analyzed,and the structural design of the coke oven head smoke dust cover was optimized.The capture efficiency and ability of the dust cover before and after optimization were compared and analyzed.The results showed that the jet trajectory gradually stabilized with the increase of jet velocity,reducing the efficiency of the top dust cover in absorbing smoke.The wind speed distribution at the front end of traditional dust collectors is smaller than that of optimized dust collectors.When the wind volume of the fan decreases from 1.0×105 m3/h to 7.0×104 m3/h,the optimized dust cover redistributes the air volume,making the wind speed at the front and lower ends and positions of the dust cover higher than that of the traditional dust cover.This indicates that the optimized dust cover has significant advantages in overcoming the problem of decreasing air volume and enhancing the suction efficiency of the front end,which is conducive to capturing the smoke diffused along the smoke guide plate and strengthening the capture efficiency of the furnace head smoke and dust.
