The invention discloses an urban garbage pyrolysis and combustion coupled coal-fired power plant power generation system. The system comprises a boiler, and the boiler is used for driving a power generator to generate electricity through a steam turbine; and the system is characterized by further comprising a garbage low-temperature pyrolysis system and a garbage drying system. According to the system, urban household garbage is subjected to low-temperature pyrolysis so that HCl in the urban household garbage can be volatilized and removed, then the generation amount of dioxin is reduced fromthe source, meanwhile, the problem of high-low-temperature corrosion of HCl in the garbage incineration process is solved, and the safety of a heated surface of a large coal-fired unit is guaranteed;and meanwhile, in the case of the large coal-fired unit, 1)a smoke purification system is high in efficiency, so that the environment problem generated in the urban household garbage incineration process is effectively solved, 2) the power generation efficiency is high so that the heat value of the urban household garbage can be efficiently utilized; and the provided system has the advantages of less investment and fast effectiveness, and has great economic and social benefits.
Description
technical field [0001] The invention relates to a system for coupling garbage treatment with a large coal-fired unit, and belongs to the technical field of garbage treatment systems. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the discharge of municipal solid waste is increasing year by year. According to data from the National Bureau of Statistics, in 2016, the removal volume of urban domestic waste in my country was 203.62 million tons. Based on the annual growth rate of 6%, it is estimated that by 2020, the removal volume of urban domestic waste in my country will reach 257.06 million tons. "Garbage siege" has become one of the important factors restricting the development of many cities and affecting the quality of life of citizens. Municipal solid waste not only occupies a large amount of land and destroys the urban landscape, but also ca...
