A blast furnace gas purification device based on steel material preparation

Abstract

The present application relates to the technical field of coal gas purification, in particular to a blast furnace gas purification device based on steel preparation, which comprises a mounting seat, a gas separation tower fixed at the top end of the mounting seat, and a limiting cover fixed in the gas separation tower, a through hole is formed in the inner wall of the limiting cover close to the gas separation tower, a stepping motor is fixed on a fixed frame, which can drive the rotating shaft to rotate in the limiting cover, realizing the quick switching of the filter separation net and the separation moisture-absorbing cotton block, without stopping the machine to complete the alternation of the blocked parts and the clean parts, ensuring the continuous and stable operation of the device, avoiding the interruption of coal gas treatment, exceeding the standard emission and causing air pollution, the extrusion separation assembly can extrude and dehydrate the saturated separation moisture-absorbing cotton block, so that it can be regenerated and reused, the scraping separation assembly can completely remove the wet ash scale on the surface of the filter separation net, avoiding the blockage of the net body pores, maintaining the filtering performance, reducing the operation and maintenance difficulty, reducing the replacement frequency of the filtering parts, and further preventing and controlling air pollution.
