Abstract

The invention discloses a totally-closed dust removal cover for a casting house in front of a blast furnace. The totally-closed dust removal cover comprises a general dust removal cover which covers the position above a main ditch in the casting house and is used for sealing the main ditch and preventing smoke diffusion, and cover plate assemblies which cover an iron ditch, a slag ditch and an emergency molten iron circulation channel in the casting house to seal and prevent smoke diffusion; the general dust removal cover and each cover plate assembly are detachably connected in a sealed manner; the general dust removal cover comprises a main ditch dust removal cover, a middle dust removal cover and a skimmer dust removal cover which are in sequential communication; the position, located above the main ditch, of the top of the ditch dust removal cover is detachably connected with a first dust removal pipeline, and the side face of the middle dust removal cover is connected with a second dust removal pipeline. Through usage of the detachable dust removal cover, the smoke in the casting house in front of the furnace can be effectively collected, and the environment of the casting house can be greatly improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of environmental protection equipment for ironmaking blast furnace production, and in particular relates to a fully enclosed dust removal cover in front of a blast furnace casting house. 【Background technique】 [0002] The blast furnace is made of steel plate, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: throat, furnace body, furnace waist, furnace bosh and hearth. Due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. The casthouse is the discharge and collection place for molten iron and slag, the final products of blast furnace ironmaking, and is a high-temperature, dusty, and labor-intensive work area in f...
