Biogas treatment device and method for anaerobic digestion production of chemical fruit and vegetable garbage

Abstract

The invention discloses a biogas treatment device and method for the anaerobic digestion production of chemical fruit and vegetable waste, and belongs to the field of chemical industry. A crushing shaft, whose outer surface has a spine-shaped structure, rotates; therefore, the crushing effect is achieved, a guide conveying shaft whose outer surface has a spiral structure, rotates; the guide conveying shaft rotates, under the action of a heating device, materials are conveniently guided and conveyed; a mounting end cover and an exhaust port can be detached; under the blocking action of a firstsplash-proof panel and a second splash-proof panel, the splashing of fruit and vegetable during the material guiding and conveying process is prevented, the cleaning is convenient; a positioning rod is positioned and clamped in a mounting block with a longitudinal section with a regular hexagon structure, the positioning rod can be effectively prevented from rotating in a staggered mode, locking and fixed mounting are conducted through locking blocks, and therefore a guiding and conveying disc is convenient to replace and mount.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a biogas treatment device and method for anaerobic digestion of chemical fruit and vegetable waste. Background technique [0002] The chemical industry uses a large amount of biogas. Biogas, chemical name: methane, as the name implies, is the gas in the swamp. People often see that in swamps, sewers or cesspools, there are bubbles coming out. If we strike a match, it can be ignited. This is the naturally occurring methane. Biogas is a kind of combustible gas produced by various organic substances through the fermentation of microorganisms under the isolation of air (reducing conditions) and at a suitable temperature and pH value. Biogas belongs to secondary energy and is a renewable energy; [0003] Fruit and vegetable waste mainly refers to fruit peels, residues, vegetable leaves, residues, etc. produced during the processing of fruits and vegetables. About 13 million tons of ...

AI Technical Summary

Problems solved by technology

[0004] At present, the research on biogas production from fruit and vegetable waste is concentrated on traditional single-phase and two-phase anaerobic digestion, due to the characteristics of high moisture content, complex composition, large volume, heterogeneity, poor fluidity, and high cellulose content of fruit and vegetable waste;

[0005] However, the existing biogas treatment device for anaerobic digestion of chemical fruit and vegetable waste is inconvenient for material conveying, and the fruit and vegetable waste is splashed during the material conveying process, which is inconvenient to clean up, and it is inconvenient to replace and install the conveying plate
