Abstract

The invention relates to an aerobic composting waste heat power generation system and a working method thereof, and belongs to the field of organic solid waste resource utilization. The system comprises a waste collection device, a main composting reaction chamber, a waste heat power generation device and a tail gas collection device, wherein a heat conduction cover is arranged at the top of the main composting reaction chamber, the upper space of the main composting reaction chamber is a waste reactor body, the lower space of the main composting reaction chamber is a leachate collection device, a filter screen is arranged between the upper space and the lower space, and the main composting reaction chamber is further connected with an aeration device; the bottom of the heat conduction cover is connected with the reactor body through a heat conduction rod; a waste heat power generation device is installed on the upper surface of the heat conduction cover and is formed by connecting a plurality of semiconductor thermoelectric power generation pieces in series, wherein the electric energy generated by the semiconductor thermoelectric power generation pieces is transmitted to an electricity storage and supply device. According to the invention, heat can be recovered from organic wastes while the organic wastes are treated, and the problem of secondary pollution caused by excessivewaste heat of traditional compost is solved.

Description

technical field [0001] The invention relates to an aerobic composting waste heat power generation system and a working method thereof, and belongs to the technical field of resource utilization of organic solid waste. Background technique [0002] In recent years, due to population growth and widespread urbanization, the problem of solid organic waste pollution has become a major obstacle on the road to sustainable development. According to statistics, about 4 billion tons of aquaculture excrement, 600 million tons of crop residues, and 100 million tons of biological waste are produced in my country every year, and the growth rate is 8-10%. If such a large amount of waste is not handled properly, it will not only occupy limited space and land resources, but also cause serious pollution and threats to the living environment. In addition, the scarcity and year-by-year exploitation of available energy have also become the challenges faced by all human beings on the road of sus...
