Garbage disposal combustion furnace and garbage disposal system

Abstract

The invention discloses a garbage disposal combustion furnace and a garbage disposal system. The combustion furnace comprises a furnace body, a blower is arranged on one side of the furnace body to ventilate a fire grate, a first combustion chamber and a second combustion chamber are sequentially arranged above the fire grate, a first secondary blower and a second secondary blower are arranged on the outside of the furnace body to ventilate the first combustion chamber and the second combustion chamber respectively, and full combustion of garbage and flue gas is facilitated. When temperature of the first combustion chamber reaches a preset value, an extraction pump extracts a garbage leachate from a leachate filter tank to spray to the first combustion chamber for gasification disposal, and the purpose of zero discharge of the garbage leachate is achieved; after the garbage is combusted in the first combustion chamber, flue gas enters the second combustion chamber for secondary high-temperature combustion, harmful substances in the flue gas are fully pyrolyzed, the flue gas combusted is disposed through a flue gas disposal part, generation of dioxin can be greatly reduced, and the flue gas finally discharged is allowed to meet the national discharge standard.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a combustion furnace for garbage treatment and a garbage treatment system. Background technique [0002] In recent years, with the increasingly serious pollution of domestic garbage in my country, the harmless treatment of garbage has attracted people's attention. At present, domestic waste incineration plants generally use activated carbon to absorb heavy metals and dioxins in the flue gas, and cooperate with the bag filter to collect the smoke, heavy metals and dioxins in the exhaust gas in the ash collected by the bag filter. Although the bag filter The flue gas at the outlet of the filter meets or is lower than the current national environmental protection emission standards, but the heavy metals and dioxins in the bag filter dust (referred to as fly ash) seriously exceed the standard. The dioxin content in the bag-trapped ashes of domestically produced waste incin...
