Municipal solid waste incineration power generation system

Abstract

The invention belongs to the technical field of waste incineration power generation, and particularly relates to a municipal solid waste incineration power generation system. The municipal solid wasteincineration power generation system comprises a shell, power generation equipment, a feeding hopper and a secondary combustion chamber, wherein the inner side of the shell is divided into a water storage cavity, a primary combustion chamber and a collection cavity through a heat conduction plate and a grating plate from top to bottom, the power generation equipment is arranged on the left side of a water inlet, and the feeding hopper is arranged at the side end of the shell and communicates with the inner side of the primary combustion chamber. According to the municipal solid waste incineration power generation system, smoke dust generated after combustion is subjected to secondary combustion through the arranged secondary combustion chamber, then heat of secondary combustion is introduced into a heat conduction pipe wound around the side wall of the water storage cavity for heating again, so that the heating efficiency is high, and meanwhile, smoke gas emission is reduced; and a heating cavity and an S-shaped pipe are arranged, so that the heat in the heat conduction pipe enters the primary heating cavity to perform primary heating on water flowing in the S-shaped pipe, waste heat utilization is achieved, and meanwhile the time for the water to reach the boiling point after entering the water storage cavity can be shortened.

Description

technical field [0001] The invention belongs to the technical field of waste incineration power generation, and specifically relates to a municipal domestic waste incineration power generation system. Background technique [0002] Solid waste generated by people in their daily life or activities that provide services for daily life, as well as solid waste that is regarded as domestic waste according to laws and administrative regulations. It mainly includes household garbage, bazaar trade and commercial garbage, public place garbage, street cleaning garbage, and garbage from enterprises and institutions. [0003] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage generated in the process of urban production and life has also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people's health. effect is also more pronounced. The ma...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of insufficient garbage combustion, it is easy to generate a large amount of harmful smoke and dust into the air, and the heat utilization rate generated during garbage incineration is low. Garbage affects the combustion efficiency of domestic waste, and it is inconvenient to clean up the material after domestic waste is burned. A kind of municipal solid waste incineration power generation system proposed by the present invention
