Description

TECHNICAL FIELD

[0001] The utility model relates to desulfurization technical field, concretely relates to a biological desulfurization treatment production system. BACKGROUND

[0002] In industrial production, biogas (waste gas) containing hydrogen sulfide is often made of different raw materials, and different contents of hydrogen sulfide are often contained in the biogas. Hydrogen sulfide is usually a harmful gas, and the hydrogen sulfide gas needs to be removed from the biogas, and the biogas needs to be desulfurized. In the prior art, biological desulfurization is an excellent way for treating biogas containing hydrogen sulfide.

[0003] The desulfurization process is to add activated sludge in the tank body, and to determine the appropriate microbial inoculation amount. Ensure that the sludge is evenly distributed in the tank body. After adding the sludge, it is ensured that it is uniformly mixed in the reactor by stirring or other means. Then the biogas is made to enter the tank body through the gas inlet. The activated sludge in the tank body fully contacts with the hydrogen sulfide in the biogas and maintains sufficient dissolved oxygen, because the oxidation of hydrogen sulfide requires sufficient oxygen. At the same time, the nutrient solution is sprayed through the spraying system, which can improve the desulfurization efficiency. The microorganisms in the sludge will use hydrogen sulfide for metabolic reaction and oxidize it into sulfate. The microorganisms use hydrogen sulfide as energy to carry out redox reaction and convert hydrogen sulfide into a more stable and harmless form. After desulfurization, the weight of the sludge will increase, and it will be discharged from the discharge pipe under the action of gravity, and the desulfurized biogas will be discharged from the gas outlet.

[0004] However, when it is necessary to replace the activated sludge after a certain period of use, the desulfurized sludge is discharged from the tank body under the action of gravity. Since the discharge pipe provided on the existing tank body is an L-shaped pipe, the sludge will easily deposit and block the corner part of the L-shaped pipe, so that the sludge cannot be discharged from the tank body. Personnel need to clean the corner part from time to time, which is very troublesome. UTILITY MODEL CONTENTS
