Abstract

The invention provides a hydrolysis reaction device for organic sulfur in blast furnace gas, belonging to the technical field of fine desulfurization of blast furnace gas. The device comprises a middle flue, a flow baffle, an inlet elbow, an inlet reducing cone, an airflow uniform-distribution plate, a rectification grid, a reactor, a hydrolysis catalyst, an internal support beam, an outlet reducing cone, an outlet elbow and a sound wave soot blower, wherein the middle flue is connected with the inlet elbow of the device; the flow baffle is arranged in the inlet elbow; the inlet elbow is connected with the inlet reducing cone; the airflow uniform-distribution plate is positioned in the inlet reducing cone; the reactor is connected with the inlet reducing cone; the rectification grid is mounted at the uppermost part of the reactor; the internal support beam is arranged in the reactor; a catalyst is placed on the upper portion of the internal support beam and arranged in the reactor; theplacing intervals of all layers of the catalyst are equal; the sound wave soot blower is placed on the upper portion of the catalyst; and the reactor is connected with an external pipeline through the outlet reducing cone and the outlet elbow of the device. The device guarantees that a rear-end coal gas user finally discharges flue gas to achieve ultralow emission of sulfur dioxide.

Description

technical field [0001] The invention relates to the technical field of fine desulfurization of blast furnace gas, in particular to a blast furnace gas organic sulfur hydrolysis reaction device. 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 sulfides, among which sulfides are mainly COS, H 2 S is the main one. The total sulfur content in blast furnace gas is generally 60-100mg / 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. [0003] Due to the late understanding of carbonyl sulfide in blast furnace gas, its composition, content, hazards and removal technology have not been paid much attention. A...
