The urban energy consumption of China is about 3/4 of the total energy consumption of China, and the urban energy demand is huge. Meanwhile, the output of wastes is also rapidly increased, and the annual output of municipal sludge, kitchen waste and kitchen waste in urban sources exceeds 2 hundred million tons. Therefore, the process of green development and resource utilization of urban organic wastes is accelerated, and the conversion of organic wastes into clean energy becomes an important development direction of urban energy systems in the future.
At present, with the continuous promotion of garbage classification work in various cities throughout the country, the separation amount of wet garbage is greatly increased, and although technologies such as methane production through anaerobic fermentation of organic wastes and biogas power generation exist, cities have no clear energy planning on the organic wastes, so that the existing organic matter energy sources such as methane thermoelectric conversion, cogeneration grid connection and the like are not well integrated into an urban energy system. The distributed energy regeneration system of the organic wastes takes a community as a core, establishes a kitchen waste combined sludge and other perishable organic solid wastes and other organic mass energy recovery capacity plants, adds an organic waste capacity link in a city, realizes methane gas cogeneration, and ensures partial power utilization and heat supply of the community.
The Chinese patent with the application number of CN202010573882.6 and the name of a carbon dioxide zero-emission type organic waste energy utilization system discloses an organic waste energy utilization system, which is characterized in that carbon dioxide and hydrogen are prepared by burning straws, and methane is generated by the carbon dioxide and the hydrogen at high temperature under the action of a catalyst, so that the carbon dioxide zero emission is realized, and the carbon dioxide zero emission is realized by utilizing the principle that calcium carbonate precipitates are generated by the reaction of carbon dioxide and a calcium hydroxide solution. The system is only a tail gas treatment technology for straw combustion, and the energy production is not applied to an urban community energy system.
The invention is a Chinese patent with application number CN202010166328.6, named as a system and a method for recycling a distributed biological waste, and provides a method for recycling the distributed biological waste, which converts the biological waste into electric energy, hot water and fertilizer. The system can generally express the generated electric energy as the electric energy which is supplied to the system for use or supplied to the outside, and the solidification of the system into the urban cell organic waste energy production link is not considered.
The application number is CN201720450696.7, the name is an urban organic solid waste resource treatment system, and relates to a waste resource treatment system capable of intensively treating various urban organic solid wastes, the urban organic solid wastes are divided into three types of recoverable substances, easily degradable organic wastes and hardly degradable organic wastes after being treated by a pretreatment unit, and the three types of recoverable substances, easily degradable organic wastes and hardly degradable organic wastes are respectively treated to generate methane and electricity. The system is based on a single treatment mode for treating the urban organic solid wastes, emphasizes on the early-stage classification mode of wastes and the treatment and disposal thereof, lacks the setting of joint energy production of different organic wastes, does not have a clear energy supply object, and cannot realize the circulation of an urban community energy system.
