Apparatus for high gravity removal of hydrogen sulfide of novel industrial gas, and technology thereof

Abstract

The invention discloses an apparatus for the high gravity removal of hydrogen sulfide of a novel industrial gas. The apparatus comprises a high gravity machine, a gas-liquid separation device, an oxidation tank, a lean liquid tank, a rotary drum vacuum filter and a rich liquid tank; the high gravity machine comprises a power device, a shell, a rotor, a liquid inlet, a liquid outlet, a gas inlet, a gas outlet and a flushing liquor inlet; the output shaft of the power device stretches into the shell and is fixedly connected with the rotor, the upper end surface of the shell is provided with the liquid inlet and the gas outlet, and the lower end of the shell is provided with the liquid outlet and the gas inlet; and the rotor is provided with a filler, the external layer of the rotor filler is provided with a backwashing device, and the backwashing device is connected with the flushing liquor inlet. The adoption of a backwashing high-gravity rotary filler bed greatly prevents the obstruction of the high gravity filler by sulfur particles. The adoption of the drum air regeneration oxidation tank substantially simplifies the process flow and substantially reduces the cost. The apparatus and the method can be used for the desulphurization of high concentration hydrogen sulfide gases in order to prevent the obstruction of the rotor filler by sulfur.

Description

technical field [0001] The technology of the present invention relates to a device and a process for removing hydrogen sulfide, in particular to a device and a process for removing hydrogen sulfide from a new type of industrial gas by supergravity. technical background [0002] Gases containing hydrogen sulfide are very common in industry, such as natural gas, oilfield associated gas, semi-water gas, coke oven gas, synthesis gas, etc. Hydrogen sulfide gas will seriously corrode metal pipes, damage equipment and measuring instruments under aerobic or humid heat conditions. If hydrogen sulfide gas is directly discharged, it will cause adverse effects on production operations, the surrounding environment and factory workers, and is one of the environmental pollutants that must be eliminated or controlled. [0003] The selection of various purification methods should be based on the nature and source of the exhaust gas. For waste gas from chemical industry and light industry, ...
