Gas desulfurization method and apparatus

Abstract

The invention discloses a gas desulfurization method and apparatus. The gas desulfurization apparatus comprises a housing, a top plate arranged at the top of the housing, and a bottom plate arranged at the bottom of the housing, as well as a jetting device arranged on the housing and a filtering device arranged inside the housing. The jetting device includes at least two jet pipes; flows jetted from the two jet pipes peripherally move in the housing in the same direction; the filtering device includes filter barrel I and filter barrel II fixed between the top plate and the bottom plate; the filter barrel II is sleeved with the filter barrel I; the bottom plate surrounded by the filter barrel II is provided with an exhaust pipe that guides out the desulfurized gas; the two filter barrels are provided with vent holes allowing gas circulation; a cavity is also arranged in each filter barrel; mesh support bars and a desulfurizing agent are arranged in each cavity. The gas desulfurization method and apparatus have the advantages that the desulfurizing agent can be changed with no interruption, and gas spill during hanging of the desulfurizing agent can be decreased.

Description

technical field [0001] The invention relates to the technical field of gas treatment, in particular to a gas desulfurization treatment method and device. Background technique [0002] Biogas and other gases produced by fermentation contain a large amount of sulfur-containing gases such as hydrogen sulfide. These gases are highly corrosive to containers. If they are directly burned or generated for power generation, they will cause great damage to equipment. Therefore, desulfurization treatment is usually required before biogas combustion. . In the desulfurization process, in order to ensure the removal efficiency of sulfide, it is necessary to replace the desulfurizer, and the replacement of the desulfurizer often interrupts the normal combustion power generation operation and affects the power generation efficiency. [0003] Document CN108130147A discloses a biogas desulfurization purification device. The device adopts complex iron desulfurization method to desulfurize bio...
