Abstract

The invention relates to a sulfur tail gas super-gravity desulfurization device and process thereof. The sulfur tail gas super-gravity desulfurization device comprises an alkali liquid storage tank and a super-gravity machine; the device utilizes alkali liquid to desulfurize sulfur tail gas, and a unique super-gravity machine structure is provided; in the structure, a hollow rotary shaft with a fluid channel is formed in a shell in a manner of penetrating through the middle axis of the shell, and a sleeve with a gas channel function sleeves the hollow rotary shaft; meanwhile, a rotary channel, which is communicated with a filling region and is provided with a spiral channel, is also formed on the basis; fluid passes through the hollow rotary shaft and then self rotation of the fluid is realized through the rotary channel, and then the fluid enters the filling region; the liquid is crushed and torn into small liquid drops under the action of a centrifugal force of liquid and is in sufficient contact with liquid reverse-flow small bubbles, and a phase interface, which is rapidly updated, is provided; crushing and tearing mixing of the fluid and gas is further realized by utilizing the self-rotation under a rotary state; the sufficient degree of gas-liquid contact is improved, and furthermore, the better sulfur tail gas desulfurization effect is obtained.

Description

technical field [0001] The invention relates to a sulfur tail gas supergravity desulfurization device, which belongs to the technical field of desulfurization. Background technique [0002] Acid gas is a common industrial discharge in industrial production, especially in refineries; sulfur tail gas is a kind of acid gas, and the gas composition contains a large amount of hydrogen sulfide and NH 3 , direct discharge will lead to damage to the environment. According to the national requirements for environmental governance, GB31570-2015 puts forward emission requirements, and the content of hydrogen sulfide and sulfur dioxide needs to be controlled at 50mg / m 3 within. [0003] At present, common desulfurization processes for sulfur tail gas include: thermal incineration method, catalytic incineration method, reduction absorption method, reduction catalytic oxidation method. The thermal incineration method is to treat the sulfur tail gas at a high temperature at 600°C, and th...
