Abstract

The invention relates to microwave desulfurization equipment, which comprises a smoke input device, a microwave generator, a microwave resonant cavity, a rotatable driving device, a microwave suppressor and a smoke output device, wherein active carbon can move circularly in the microwave resonant cavity. In the invention, smoke enters the microwave resonant cavity in which the active carbon can move circularly from the smoke input device; and under the continuous excitation of a microwave electromagnetic field, sulfur dioxide in the smoke reacts with the active carbon which moves circularly in the microwave resonant cavity and is reduced into elemental sulfur, so the sulfur dioxide concentration of the smoke is lowered and the treated smoke is exhausted after the elemental sulfur is recycled on a built-in sulfur recovery device of the smoke output device. The device has the advantages of high desulfurization efficiency, low operating cost, simple process and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to the technical field of industrial flue gas treatment, and mainly relates to a device for removing harmful gases such as sulfur dioxide in the flue gas by adopting activated carbon in a circular movement mode under the induction of microwave catalysis. technical background [0002] At present, the fuels used in industrial production mainly include coal, heavy oil, light diesel oil, natural gas, etc., in which organic sulfides and combustible sulfides will produce a large amount of SO in the combustion process. 2 smoke. There are more sulfur-containing substances in the raw materials of the ceramic industry, such as FeS 2 , Fe 2 (SO 4 ) 3 , CaSO 4 、Na 2 SO 4 etc. During the sintering process of the ceramic green body, through a series of oxidation-reduction reactions, SO will also be generated. 2 The gas is discharged to the atmosphere through the flue and ...
