Abstract

The invention provides a moving bed type blast furnace gas desulfurization device and a desulfurization method thereof. The blast furnace gas desulfurization device comprises a shell, a catalyst partition plate set is arranged in the shell in the axial direction, and the catalyst partition plate set comprises an inner ring partition plate piece and an outer ring partition plate piece which are coaxially nested from inside to outside; and an annular cavity formed between the inner ring partition plate piece and the outer ring partition plate piece is filled with a catalyst, and a feeding port is formed in the top, where the annular cavity is located, of the shell. A cavity defined by the inner ring partition plate piece is an exhaust channel, a cavity between the outer ring partition plate piece and the shell is an air inlet channel, and an air inlet communicated with the air inlet channel is formed in the bottom of the shell. Compared with a traditional fixed bed packed tower, the resistance in the tower is reduced, the moving bed improves the utilization rate of the catalyst, and the blast furnace gas desulfurization efficiency can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of desulfurization, and relates to a blast furnace gas desulfurization device and a desulfurization method thereof, in particular to a moving bed type blast furnace gas desulfurization device and a desulfurization method thereof. Background technique [0002] Blast furnace gas is a by-product of the iron-making process. As the largest combustible gas produced by iron and steel enterprises, it has a wide range of uses and is generally sent to user units such as blast furnace hot blast stoves, steel rolling heating furnaces, and gas power generation for use as fuel. At present, users of blast furnace hot blast stove, steel rolling reheating furnace, gas power generation and other users all require the combustion of tail gas SO 2 Reach ultra-low emission limits, while existing blast furnace gas purification processes cannot meet SO 2 Control requirements. The current technical route mainly includes source con...
