Example Embodiment

[0016] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] The invention provides a biomass anaerobic fermentation tank pneumatic stirring system and a method for stirring high-concentration anaerobic fermentation broth. The specific method is as follows:

[0018] The biogas produced by anaerobic fermentation in the anaerobic fermentation tank (8) is processed by the dehydration and desulfurization purification equipment system (10) and then passed into the membrane decarbonization equipment (2). After the biogas is decarbonized, the exhaust carbon dioxide is passed into the compressor (5). ) Compressed and buffered in the high-pressure carbon dioxide gas storage tank (7), and the compressed carbon dioxide is passed into the nozzle nozzle (9) at the bottom of the anaerobic fermentation tank to st...

Abstract

The invention discloses a pneumatic agitating system of a biomass anaerobic fermentation tank, and belongs to the technical field of biomass anaerobic fermentation. Biogas, generated from the anaerobic fermentation, is supplied into membrane decarburization equipment after being processed by virtue of dehydrating equipment and desulfurization and purification equipment, so that purified methane is obtained in one aspect and tail gas carbon dioxide, which serves as a pneumatic agitating power source of the system provided by the invention, is obtained in the other aspect; after the biogas is decarburized, the tail gas carbon dioxide, which is compressed by virtue of a compressor, is supplied into a carbon dioxide high-pressure storage tank; the compressed high-pressure carbon dioxide gas is supplied into the anaerobic fermentation tank by virtue of an agitating ventilation pipe, so that high-concentration anaerobic fermentation slurry is agitated. The pneumatic agitating system provided by the invention, which conducts agitating by virtue of high-pressure carbon dioxide gas, is high in anaerobic fermentation efficiency and the pneumatic agitating system has the characteristics of being high in agitating efficiency, simple to operate, safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of biomass anaerobic fermentation, in particular to a pneumatic stirring system of a biomass anaerobic fermentation tank and a high-concentration biomass anaerobic fermentation pneumatic stirring method. Background technique [0002] With the support of national policies for organic waste resource utilization anaerobic fermentation biogas production projects, intensive large-scale biogas projects have shown a good development trend in my country, and the government has increased technical investment in biomass energy and resource utilization and financial support. [0003] The anaerobic fermentation of organic waste to produce biogas technology can reduce solid waste and gas pollution emissions, reduce the greenhouse effect, and improve resource utilization. Therefore, the anaerobic fermentation technology of biomass has been paid more and more attention by technicians and experts in the industry, and gradua...
