Heating system for garage type dry fermentation and operation control method thereof

Abstract

The invention relates to a heating system for garage type dry fermentation and an operation control method thereof. Based on the concept of utilization of energy generated by microbial self-heating, partial utilization of hot water generated by an auxiliary heater, comprehensive utilization of energy cascade and system energy consumption coefficient (COPs) in a dry anaerobic fermentation process, a spiral coil heat exchanger is used for preheating outdoor air led in at the worst operating condition, the auxiliary heater utilizes an electric boiler to heat an auxiliary heating loop, an air source heat pump unit improves a low grade heat source (air) to a high grade heat, and the heating system for the garage type dry anaerobic fermentation can achieve a air source heat pump direct heating mode and an air source heat pump-electric boiler combined heat supply heating mode. The operation control method of the heating system solves the problem that system modes switch optimal operation automatically under different weather conditions so as to achieve economy, energy conservation and environment protection of the whole system, and contributes to promote development and industrialization process of dry anaerobic fermentation engineering rapidly.

Description

technical field [0001] The invention belongs to the application field of new energy development and energy saving, and specifically relates to a garage-type dry fermentation heating system and an operation control method. Background technique [0002] With the development of China's economy and the rapid progress of urbanization, the output of urban waste is also increasing day by day, which has become one of the important factors restricting the healthy development of cities. There are many ways to deal with urban organic waste, among which sanitary landfill, composting, incineration and anaerobic digestion are more common. Anaerobic digestion can reduce the pollution of organic waste and carbon dioxide emissions. It occupies less land and causes relatively little secondary pollution to the environment. At the same time, it can generate biogas. In today's energy shortage, it has attracted more and more attention. [0003] Anaerobic digestion process is divided into wet met...
