Solid organic waste aerobic fermentation reactor

Abstract

The invention discloses a solid organic waste aerobic fermentation reactor which comprises a fermentation tank, a blower system, an air return system and a closed film system, wherein the closed film system covers a tank opening of the fermentation tank; the blower system comprises an air blower and a gas supply pipe; the air return system comprises a gas return pipe and an exhaust emission pipe;one end of the gas supply pipe is connected with the fermentation tank, and the other end is connected with the air blower; one end of the gas return pipe is connected with the tank opening of the fermentation tank, and the other end is connected with the air blower and the exhaust emission pipe at the same time; a valve is arranged between the gas return pipe and the air blower and between the gas return pipe and the exhaust emission pipe respectively; the closed film system comprises a closed film and a closed device; a condensate discharge system comprises a guide plate and a condensate collection tank; the guide plate is arranged at the tail end of the closed film; and the condensate collection tank is arranged below the guide plate. Through the solid organic waste aerobic fermentation reactor, the solid organic waste is quickly heated, the heat utilization rate of the solid organic waste is high, the odor is closed, and the environmental effect is good.

Description

technical field [0001] The invention relates to the technical field of organic waste fermentation equipment, in particular to an aerobic fermentation reactor for solid organic waste. Background technique [0002] The aerobic fermentation process is the process of organic matter under aerobic conditions, using the exoenzyme secreted by aerobic microorganisms to decompose solid organic waste into dissolved organic matter, which then penetrates into cells. Through metabolic activities, microorganisms oxidize some of the organic matter into simple inorganic matter, which provides the energy required for biological life activities, and the other part of the organic matter is converted into the nutrients needed by the organism to form new cell bodies, so that the microorganisms continue to proliferate. During this process, a large amount of energy is released, except for a small part that provides energy for cytoplasmic synthesis, and the rest is released in the form of heat, whic...

AI Technical Summary

Problems solved by technology

[0003] During the aerobic fermentation process, the moisture content of solid organic waste drops from the initial 60% to 70% to about 40% of the final output. The form of aerobic fermentation reactor is very important for the treatment efficiency of solid organic waste. At present, Commonly used forms such as strip piles and fermentation tanks have disadvantages such as large air volume, poor environment, and difficulty in odor control during the treatment process.
