Multi-stage catalyzed sorption reactor

Abstract

The invention discloses a multi-stage catalyzed sorption reactor which comprises a reactor body, catalyzed sorption beds, charging holes, discharge holes, gas inlets and a gas outlet, wherein the catalyzed sorption beds are fixed in the reactor body to divide the interior of the reactor body into independent catalyzed sorption spaces; the discharge holes are formed in the reactor body on the upper surfaces of the catalyzed sorption beds; the charging holes are formed in the reactor body in the middles of the independent catalyzed sorption spaces formed by the upper surfaces of the catalyzed sorption beds; the gas inlets are formed in the reactor body on the lower surfaces of the catalyzed sorption beds; and the gas outlet is formed at the upper part of the reactor body. The charging holes and the discharge holes are used for filling high-efficiency converted-sorption activated carbon desulfurizing agents; acid gas enters the reactor body through the gas inlets, and conducts sorption and catalysis with the high-efficiency converted-sorption activated carbon desulfurizing agents through the catalyzed sorption beds; the high-efficiency converted-sorption activated carbon desulfurizing agents convert sulfur-bearing matters in the acid gas to simple sulfur, simple sulfur is sorbed in micropores of a catalyst; and desulfurized tail gas is discharged out of the reactor body through the gas outlet of the reactor body.

Description

technical field [0001] The invention relates to a reaction device for catalyzing and adsorbing sulfur, in particular to a kind of high-efficiency conversion and absorption activated carbon desulfurizer to treat inorganic sulfur and organic sulfur absorbing acid gas at low temperature. Background technique [0002] In modern industry, Claus device and Claus extension process are generally used to treat tail gas, or ammonia liquid absorption after tail gas incineration or amine liquid absorption after hydrogenation and reduction, but Claus method is used to solve fossil fuel combustion and geothermal When hydrogen sulfide is generated during power generation, the tail gas discharged under certain conditions cannot meet the standard; and the process of absorbing ammonia liquid after tail gas incineration or hydrogenation and reduction with amine liquid is complicated, which is not conducive to the development of industrial production. Moreover, in modern industrial production, ...

Problems solved by technology

[0002] In modern industry, Claus device and Claus extension process are generally used to treat tail gas, or ammonia liquid absorption after tail gas incineration or amine liquid absorption after hydrogenation and reduction are used, but Claus method is used to solve fossil fuel combustion and geothermal energy. When hydrogen sulfide is generated during power generation, the tail gas discharged under certain conditions cannot meet the standard; and the process of absorbing ammonia liquid after tail gas incineration or hydrogenation and reduction with amine liquid is complicated, which is not conducive to the development of industrial production

Moreover, in modern industrial production, flammable gases such as coke oven gas and natural gas generally adopt wet desulfurization, and wet desulfurization will cause certain pollution to the atmospheric environment.
