Low-corrosion and high-efficiency city garbage combusting system and method

Abstract

The invention discloses a low-corrosion and high-efficiency city garbage combusting system and method. The low-corrosion and high-efficiency city garbage combusting system comprises a boiler system and a marsh gas auxiliary combusting system. The boiler system comprises a combusting room with a cavity. The combusting room is provided with a feeding port, a slag discharging port, an air inlet and an exhaust opening. The marsh gas auxiliary combusting system comprises a combusting device, a dehumidifying device and a fermenting device used for fermenting kitchen garbage. The combusting device is connected to the combusting room, and the combusting device, the dehumidifying device and the fermenting device are communicated in sequence and in series. By means of the low-corrosion and high-efficiency city garbage combusting system, the difference of the water content of garbage is small, the combustion heat value and the water content are uniform, and corrosivity is low.

Description

technical field

[0001] The invention relates to the field of municipal waste treatment, in particular to a low-corrosion high-efficiency municipal waste incineration system and a method thereof. Background technique

[0002] The annual output of urban waste in my country has reached the level of 100 million tons. Now the commonly used disposal methods include landfill, composting, pyrolysis and incineration, etc. Among them, landfill requires a large area and will pollute the environment. Composting and pyrolysis are harmful to the environment. The composition requirements of waste are high and the economic efficiency is low. Since waste incineration power generation technology can not only process waste as resources, but also has a small footprint and strong processing capacity, it has gradually become the main method of solid waste treatment.

[0003] The most widely used in the existing waste incineration power generation system is the mechanical grate boiler. This boiler ...
