Problems solved by technology

[0003] At present, in order to maintain the high-temperature environment of high-temperature aerobic fermentation, most of them rely on external heating, such as hot water, heat transfer oil or hot air. Extracting the humid air in the fermenter will also cause a large amount of odor to be processed, and the cost of collection and treatment will be high; while in the process of high-temperature aerobic fermentation, the heat generated by fermentation will be taken away by the high-temperature and humid air, Without recycling, a large amount of heat energy is lost, which greatly increases the operating cost of the system; in the prior art, the hot and humid waste gas is usually directly refluxed, but the water vapor is brought back to the reactor and absorbed by the fermentation material. Effective removal cannot achieve effective reduction of materials, and because the water is not taken away, the moisture content of the fermentation materials in the fermentation tank is relatively high, the fermentation efficiency is low, and the fermentation effect is also poor

Abstract

The invention discloses a high-temperature aerobic fermentation system capable of automatically removing water and recycling heat. The system comprises an aerobic fermentation reactor, a steam-water separator and a circulating fan which are sequentially connected through an air pipe, wherein a bypass pipeline I and a bypass pipeline II are arranged on the part, located between the steam-water separator and the circulating fan, of the air pipe; the bypass pipeline I is close to the circulating fan and is connected with the steam-water separator; an adjusting air valve I is arranged on the bypass pipeline I; and an adjusting air valve II is arranged on the bypass pipeline II. By utilizing the system, the fermentation heat can be fully recycled, so the stability of the fermentation temperature of the system is effectively ensured; heat exchange is carried out between fresh air and fermentation tail gas in the steam-water separator, so tail gas dehydration efficiency can be effectively improved, and fresh air entering a fermentation tank is heated; and since heat in the tail gas is recycled, energy consumption of the system is greatly reduced, and meanwhile, fermentation temperature fluctuation caused by the fact that cold air directly enters the fermentation reactor is reduced.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a high-temperature aerobic fermentation system capable of automatic water removal and heat recycling. Background technique [0002] The main purpose of aerobic fermentation is to effectively realize the harmlessness and reduction of organic manure. According to the characteristics of aerobic fermentation, maintaining the high temperature of the system can make the system have higher fermentation efficiency, so that bacteria and pathogens can be more fully killed, and it can also accelerate the degradation of antibiotics in manure, and the harmlessness is more thorough. ; but the high-temperature aerobic fermentation process will produce a large amount of high-temperature and high-humidity odor. An excellent reactor not only needs to collect and harmlessly treat the waste gas generated during the fermentation process, but also needs to exhaust the exhau...
