Abstract

The invention discloses a device for marsh gas resource utilization of kitchen waste. The device includes an anaerobic fermentation system and a marsh gas purification system. The anaerobic fermentation system is internally equipped with a crushing component for crushing kitchen waste and a heating component for providing constant anaerobic fermentation temperature. The marsh gas purification system is internally provided with a dedusting component and a biological purification component, the dedusting component is in butt joint with a gas channel, the marsh gas produced by the anaerobic fermentation system is subjected to dedusting purification, and the biological purification component and the dedusting component are in series connection to output dedusted marsh gas after biological desulfurization. According to the invention, kitchen waste is subjected to anaerobic fermentation to produce marsh gas, and the marsh gas is purified to realize resource utilization of marsh gas, the device provided by the invention is convenient and efficient for use, and effectively solves the treatment problem of kitchen waste and achieves effective use of marsh gas resources.

Description

technical field [0001] The invention belongs to the kitchen garbage processing technology, and in particular relates to a device for utilizing the kitchen garbage as a biogas resource. Background technique [0002] Food waste has the characteristics of high moisture content, high organic matter content, high fat, and high salinity. It is easy to ferment, deteriorate, rot, breed pathogenic microorganisms, emit foul odor, generate a large amount of greenhouse gases, and cause complaints from residents. Food waste The effective governance of the environment is related to environmental protection and affects people's physical and mental health. [0003] In view of the significant impact of food waste on the environment, it needs to be effectively treated. The traditional treatment methods include sanitary landfill and incineration. The sanitary landfill method has a large processing capacity and relatively low operating costs, but it occupies a large area and has secondary poll...
