Problems solved by technology

[0005] The existing biological desulfurization technology for biogas cannot uniformly disperse the biogas entering the desulfurization device, so that the nutrient solution and biogas cannot be fully mixed and reacted. Convenient, it is easy to cause the packing frame to be blocked and hardened, which will affect the passage of biogas and cause poor desulfurization effect on biogas

Abstract

The invention discloses a biogas purification device based on a biological desulfurization technology and a purification method thereof, and belongs to the technical field of renewable energy utilization. The device mainly comprises a first-stage desulfurization device, a second-stage desulfurization device, a sulfur reactor, a uniform mixing and liquid pumping element, an intelligent element anda power supply, wherein a gas buffer dispersion box is arranged at a first biogas outlet; two biogas dispersing and buffering elements with different structures are arranged in the gas buffering and dispersing box; biogas entering the second-stage desulfurization device is uniformly dispersed and fully contacted with a horizontal filler frame, the desulfurization effect of the biogas is improved,the pressure of the biogas is detected in the dispersion process, the pressure build-up of the gas dispersing and buffering box is avoided, the potential safety hazard is avoided, the safety and reliability are realized, and the purification efficiency is high; and by arranging the horizontal filler frame convenient for dismounting or mounting the structure, a filler is convenient to clean or replace regularly, and the biogas purification effect is improved.

Description

technical field [0001] The invention belongs to the technical field of renewable energy utilization, and in particular relates to a biogas purification device and a purification method based on biological desulfurization technology. Background technique [0002] Biogas is a valuable green energy with great development potential. It is a mixed gas produced by the fermentation of microorganisms under anaerobic conditions. Biogas is produced in different environments, such as landfills, Anaerobic fermentation of organic matter in sewage sludge and biological waste can produce biogas. In addition, there are abundant resources for producing biogas in rural areas. Biogas is a flammable mixed gas, the main component is CH 4 , CO 2 , a small amount of H 2 S, H 2 , O 2 , CO, N 2 Wait. [0003] The purification of biogas is mainly for the H in the biogas 2 S, H 2 O.CO 2 H2S removal is mixed with halogenation. Among them, hydrogen sulfide is toxic and will corrode anaerobic d...
