Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a novel biogas biological desulfurization device. Background Art

[0002] A cattle farm is a facility that specializes in raising cattle, mainly used for the feeding, reproduction and management of cattle. The biogas produced by cow dung can not only solve the problem of waste, but also obtain reusable clean energy. When producing and processing biogas, a biogas biodesulfurization device is required.

[0003] After searching, the patent number is CN208346109U, and the name is a utility model of a biogas biological desulfurization device, including a desulfurization tank. Through research and analysis, it is found that although it has novel structure, ingenious conception, and easy use during use, it can purify sulfur-containing biogas to the greatest extent and effectively ensure the quality of biogas. However, it still has the following disadvantages to a certain extent.

[0004] For example, it does not have a scraping function. The desulfurization bacteria absorb hydrogen sulfide from the mixed biogas and convert them into elemental sulfur, and then into sulfuric acid. The generated sulfuric acid flows to the bottom of the inner cavity of the tower under the buffering and neutralization effect of the nutrient solution. When the waste liquid is discharged, part of the waste liquid is easy to adhere to the tower wall. If it cannot be scraped and cleaned, it will form dirt, which will affect the subsequent desulfurization effect. In order to solve the above technical problems, we have designed a new type of biogas biological desulfurization device. Utility Model Content
