An air inlet communicated with the air inlet chamber is formed in the bottom of the shell.

Description

technical field [0001] The invention belongs to the technical field of blast furnace gas hydrolysis, and relates to a hydrolysis reaction device and a hydrolysis method for organic sulfur in blast furnace gas. Background technique [0002] Blast furnace gas is a combustible gas produced in the blast furnace ironmaking process, which can be used as fuel and widely used in boilers, blast furnace hot blast stoves, steelmaking heating furnaces and other processes. The main components of blast furnace gas are: CO, CO 2 , N 2 And a small amount of hydrocarbons and sulfur-containing components. The total sulfur content in blast furnace gas is generally 150-300mg / Nm 3 , of which organic sulfur accounts for 3 / 4 and inorganic sulfur accounts for 1 / 4. Inorganic sulfur can be easily removed from gas by alkaline washing. Organic sulfur is stable in nature and will cause serious corrosion of equipment and pipelines and pollute the atmospheric environment. It is the primary removal ob...
