The invention discloses a heat exchange pre-heating system applied to anaerobic fermentation of feces, which comprises a feces collecting tank, a regulating tank, an anaerobic fermentation reaction chamber, a biogas slurry tank and a heating pre-heating loop, and the feces collecting tank, the regulating tank, the anaerobic fermentation reaction chamber and the biogas slurry tank are communicated through pipelines. The heating and pre-warming loop comprises a pre-warming loop and a heating loop, and a mixing and homogenizing device and a solid-liquid separation device are arranged in the excrement collecting tank and used for homogenizing and solid-liquid separation of excrement; after solid-liquid separation, the mixture is pushed by a pump through a pipeline to enter an adjusting tank for full mixing and homogenizing pretreatment; the pretreated manure raw materials are conveyed into an anaerobic fermentation reaction chamber through a pipeline under the pushing of a pump to be subjected to anaerobic fermentation reaction, the anaerobic fermentation reaction chamber is provided with an anaerobic fermentation tank and a stirring device, and the manure raw materials are subjected to anaerobic fermentation in the anaerobic fermentation reaction chamber to form biogas slurry; and after heat exchange with the heat exchanger, the biogas slurry flows into the biogas slurry pool.
Description
technical field [0001] The invention relates to a heat exchange preheating system applied to anaerobic fermentation of manure. Background technique [0002] With the scarcity of resources and increasingly serious environmental pollution, the world pays more and more attention to energy-saving and environmental protection production. In the manure anaerobic fermentation system, the "turning waste into wealth" of environmental pollutants has been realized, and at the same time, the provision of biomass energy and other auxiliary products has been realized, and resource utilization and clean production have been realized. However, the current core aspect of the anaerobic fermentation system - heat energy utilization, there is a situation in which the waste heat utilization is not perfect. lost. High energy consumption and high cost reduce the reliability and feasibility of the anaerobic fermentation system. Contents of the invention [0003] The invention provides a method...
