Problems solved by technology

Dry desulfurization requires frequent replacement of desulfurizers, resulting in high labor intensity and high operating costs, and large-scale applications have been eliminated
Wet desulfurization uses lye (NaOH or Na2CO3) in countercurrent contact with biogas to remove hydrogen sulfide, and passes a specific catalyst (naphthoquinone) in the regeneration tank to catalyze the hydrogen sulfide absorbed by the lye into elemental sulfur and thio Sulphate, sulfuric acid, at the same time, most of the lye is regenerated, and hydrogen sulfide can continue to be absorbed in the washing tower. The process is complex and requires special personnel to be on duty, and the investment cost of equipment is large

Abstract

The invention discloses a cow dung disposal system which comprises a cow dung purifying device and a cow dung using device. The cow dung disposal system can purify and use cow dung, which is not beneficial to recycle of the cow dung and desulfurization of biogas. By purifying the cow dung, the desulfurizing efficiency of the cow dung can be also improved.

Description

Technical field: [0001] The invention belongs to the field of biogas fermentation, in particular to a cow dung treatment system. Background technique: [0002] Biogas is a biomass energy and is a renewable resource. With the rapid development of the economy, the anaerobic digestion technology of organic waste and high-concentration organic wastewater has been rapidly developed and improved, and the clean development and utilization of biogas has gradually become the main research direction. Biogas is a mixed gas, mainly containing CH4 and CO2, in addition, it also contains H2S. Hydrogen sulfide is corrosive to pipelines, instruments, and metal equipment, and the sulfur dioxide produced by burning hydrogen sulfide also pollutes the environment to a certain extent. How to remove hydrogen sulfide in biogas is a key link in the biogas production process. [0003] Methods for removing hydrogen sulfide from biogas include dry desulfurization, wet desulfurization and biological d...
