Description

Technical Field

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

[0002] Biogas is a high-grade clean energy source, which is widely used to improve the quality of life. The components of biogas are methane and carbon dioxide, and also contain a small amount of hydrogen sulfide, carbon monoxide, ammonia, hydrogen, etc. The hydrogen sulfide in biogas will not only seriously endanger human health, but also corrode the cement and steel structure of the biogas plant, and damage the transmission pipeline. After the biogas is burned, the hydrogen sulfide will be converted into sulfur oxides and discharged into the air, forming acid rain and polluting the environment. However, my country's environmental protection standards stipulate that when using biogas energy, the mass concentration of hydrogen sulfide in biogas shall not exceed 20mg / m3. Therefore, before using biogas as a clean energy source, the hydrogen sulfide must be removed.

[0003] At present, during the use of existing biogas biological desulfurization devices, biogas is usually transported to a desulfurization tower through a pipeline for biogas desulfurization. However, after long-term use, a large amount of impurities will adhere to the inner wall of the biogas biological desulfurization tower. The traditional cleaning method is often to use a spraying method, but simple spraying is difficult to remove the attached impurities, which will result in poor cleaning effect.
