Abstract
The invention discloses a heat-preserving organic waste dry-type anaerobic fermentation system, which comprises a fermenter, a heat exchange device, a heat supply device, a control valve, a circulating pump, a temperature measurement device and a control device. The heat exchange device is arranged on the fermenter, and is connected with the heat supply device through pipelines via the control valve and the circulating pump, so as to form a circulatory heat supply system; the temperature measurement device is arranged in the fermenter, is electrically connected with the control device, and isused for detecting the temperature in the fermenter; and the control device is electrically connected with the control valve and the circulating pump, is used for opening the control valve and the circulating pump so as to allow heat supply media supplied by the heat supply device to enter the heat exchange device to heat the fermenter when the temperature measurement device detects that the temperature in the fermenter is lower than the set temperature, and is used for closing the circulating pump and the control pump so as to stop conveying the heat supply media supplied by the heat supply device to the heat exchange device when the temperature measurement device detects that the temperature in the fermenter is higher than the set temperature. The system has the advantages of simple structure, convenient control, accurate temperature adjustment and the capability of effectively controlling the temperature changes of the fermentation system.
Description
technical field [0001] The invention relates to a fermentation system, in particular to a thermal insulation dry anaerobic fermentation system for organic waste. Background technique [0002] Biomass waste, which exists in large quantities in municipal solid waste, has the characteristics of large amount, easy biodegradation and high water content, and has become the main source of solid waste polluting the environment. The use of anaerobic fermentation technology to treat biomass organic waste can not only realize the harmless treatment of waste, but also recover useful substances. For example, the generated biogas can be used for power generation, heating, lighting, etc., and the digested residue and biogas slurry are High-quality organic fertilizers can be applied to farmland to improve soil and increase fertilizer efficiency. [0003] Dry anaerobic digestion technology is a new type of anaerobic digestion treatment technology for organic waste developed in recent years....
