AI Technical Summary

Technical Problem

Traditional blast furnace gas purification equipment with fixed packed bed structure suffers from low purification efficiency and low packing utilization, which is especially evident in small enterprises.

Method used

Design an offline material replacement blast furnace gas desulfurization system. It adopts a fixed packing bed structure. By setting three rows of staggered flow-around baffles and an automatic detection system in the packing bed, the angle and gap of the flow-around baffles are adjusted to extend the contact time of the gas in the packing and improve the purification efficiency. The use of the packing is optimized through the automatic detection and control system.

Benefits of technology

It significantly improves the utilization rate and purification efficiency of the packing material, increasing the utilization rate from less than 50% to over 95% and the purification rate from 80,000 m3/h to 150,000 m3/h, making it suitable for the production needs of small enterprises.

Abstract

The utility model discloses a blast furnace gas fine desulfurization system capable of replacing materials offline, which comprises a dechlorination purification unit, a hydrolysis purification unit and a desulfurization purification unit which are sequentially connected in series along the gas flowing direction, and is characterized in that at least one fixed filler purification area is arranged in a shell of each purification unit; streaming baffles which are horizontally arranged on the whole are further arranged in the fixed filler purification area, the streaming baffles are horizontally and alternately arranged into three columns which are uniformly arranged in the vertical direction, and the streaming baffles on the left side and the right side and the streaming baffles in the middle are vertically staggered and arranged at intervals. The utility model relates to a blast furnace gas fine desulfurization system based on a fixed packed bed structure. The blast furnace gas fine desulfurization system can be adaptively adjusted according to different stages of the service life of packing so as to improve the purification efficiency and the use efficiency of the packing. And the device is particularly suitable for production requirements of small enterprises with low requirements on treatment capacity.
