The incinerator 10 includes a combustion chamber 11, a garbage inlet 12 at the upper end, an ash discharge port 13 and a secondary combustion chamber 14 at the lower end, and is connected to the waste heat recovery boiler 15.
Air is supplied to the combustion chamber 11 through the pipe 16.
The solid waste enters the combustion chamber 11 from the inlet 12, is combusted by sufficient contact with the air, and the gas generated after the secondary combustion of the secondary combustion chamber 14 is heat-exchanged by the waste heat recovery boiler 15, and then enters the cooling tower 20 through the exhaust pipe 15A. The gas is cooled by water to a temperature acceptable to the bag filter or the like in the dust collector 30 while preventing the synthesis of dioxins.
The dust remover 30 includes a built-in bag filter, the clean air is discharged through the exhaust system 40, and the fly ash of the low fly ash and the discharge port 13 is collected and returned to the separator 50.
Upper separator
Upper separator
The separator 50, a wind sorter 51, a screen 52, separator 53 non-ferrous metals and non-ferrous separator 54.
Among them, non-ferrous non-ferrous metals are recovered, metal compounds composed of iron and acidified iron, and additive sulfur are returned to the system.
By the interaction of the additive sulfur and the metal compound, the chloride is inhibited, thereby preventing corrosion of the chloride. Among them, the metal compound and the sulfate formed by sulfur will adhere to the surface of the heat transfer tube like a protective film, so that the corrosion of the device by the chloride can be prevented.
The melting point/degree Celsius of the metal chloride that needs to be known:
Potassium chloride: 776
Zinc chloride: 283
Stannous chloride: 247
pbCL2: 501
The formula you need to use:
2KCl+SO2+H2O+1/2O2→K2SO4+2HCl
ZnCl2+SO3+H2O→ZnSO4+2HCl
SnCl2+SO3+H2O→SnSO4+2HCl
PbCl2+SO3+H2O→PbSO4+2HCl
Among them, the additive sulfur may be sulfur, or may be an inorganic sulfide or an organic sulfide, because sulfur oxides are finally formed by combustion, mainly for changing chlorides, such as: zinc sulfate, aluminum sulfate, ammonium sulfate, cobalt sulfate. , nickel sulfate, ammonium hydrogen sulfate, ferric sulfate, potassium sulfate, manganese sulfate, copper sulfate, ammonium sulfide, hydrogen sulfide, iron sulfide, copper sulfide, nickel sulfide, cobalt sulfide, chromium sulfide, mercaptans, organic sulfides, Organic disulfides, thiophenes and their homologues, vulcanized rubbers in organic sulfur compounds, and the like.
