Compost fermentation device

Abstract

The invention discloses a compost fermentation device, and relates to the technical field of fermentation equipment. The compost fermentation device comprises a smashing device, a compost device and a gas recycling and purifying device. The smashing device is used for smashing materials, and a feeding port of the compost device is in sealed communication with a discharging port of the smashing device; an exhaust port of the composting device is in sealed communication with a gas inlet of the gas recovery and purification device, and the gas recovery and purification device is used for purifying gas generated in the fermentation process and recovering ammonia gas, hydrogen sulfide gas and organic gas in the gas recovery and purification device; a smashing cavity is arranged in the smashing device, the discharging port of the smashing device is formed in the bottom of the smashing cavity, the feeding port of the smashing device is formed in the top of the smashing cavity, and the feeding port of the composting device is located below the discharging port of the smashing device, so that the compost fermentation device provided by the invention improves the resource utilization rate, saves electric power resources and does not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of fermentation equipment, in particular to a compost fermentation device. Background technique [0002] In agricultural production, fallen leaves of fruit trees, crop stalks, soybean meal, cotton meal, and stems and leaves of creeping crops are all regarded as waste by us, and often cannot be properly disposed of; in the breeding industry, animal manure is the main force of breeding pollution. For farmers, the treatment of feces is regarded as the top priority; distiller's grains, vinegar grains, sugar residues, etc. in industrial production; domestic waste, kitchen waste, etc. generated in household life; river sludge and sewers for urban management Sludge, etc., the pollution problem caused to the environment has already attracted our attention; there are many kinds of existing treatment methods and devices, but the treatment of the volatile gas produced in the fermentation process is simply purified and ...

[0002] In agricultural production, fallen leaves of fruit trees, crop stalks, soybean meal, cotton meal, and stems and leaves of creeping crops are all regarded as waste by us, and often cannot be properly disposed of; in the breeding industry, animal manure is the main force of breeding pollution. For farmers, the treatment of feces is regarded as the top priority; distiller's grains, vinegar grains, sugar residues, etc. in industrial production; domestic waste, kitchen waste, etc. generated in household life; river sludge and sewers for urban management Sludge, etc., the pollution problem caused to the environment has already attracted our attention; there are many kinds of existing treatment methods and devices, but the treatment of the volatile gas produced in the fermentation process is simply purified and then discharged into the atmosphere In this volatile gas, there are a large number of gases with application value, such as NH 3 、H 2 S, etc., thus making the resources not fully utilized and polluting the atmosphere
