Part, the foul smell in boil-off gas is removed by plasma Odor control device；
S2：By feed device, by step S1, treated that rubbish send to pyrolytic tank decomposes, and the flue gas after decomposition is introduced
Burner burns, and the high-temperature flue gas after burning is drained into flue gas set by flue, is packed by heat exchanger and hot water
Row heat exchange；
S3：Heat is passed in drying chamber to the rubbish heating in it by the water in hot water jacket after carrying out heat exchange in step s 2,
Accelerate rate of drying and drying effect；Flue gas is sleeved on be filled with high-temperature flue gas after ensured under minimum temperature in pyrolytic tank by heat transfer
Limit；
S4：Flue gas in flue gas set after smoke eliminator eventually by being discharged.
The combustion process of aforementioned step S2, is passed through by combustion supporting inlets in air, natural gas, oven gas, pure oxygen, coal dust
One or more combinations.
The prior art compares, and the structure and its method that small-sized rubbish of the present invention burns, it includes drying chamber to the structure, dry
Tank is connected by feed device with pyrolytic tank, and pyrolytic tank is connected with burner, is respectively equipped in the upper end of drying chamber and lower part
Ion Odor control device and hot water jacket, the lower part of pyrolytic tank be equipped with flue gas set, flue gas set on be equipped with pipe, pipe with
Smoke eliminator is connected, and is equipped with combustion supporting inlets on the burner and is connected to the flue of flue gas set, in flue gas
Pipeline is equipped with heat exchanger, and heat exchanger is connected by circulating line with hot water jacket.This method it include the following steps：S1：Life
Rubbish enters drying chamber, and the moisture content in the unofficial biography thermal evaporation rubbish of fever and hot water jacket is accumulated using house refuse, by it is equal from
Sub- Odor control device removes the foul smell in boil-off gas；S2：By feed device, by step S1, treated that rubbish is sent to pyrolysis
Tank is decomposed, and the flue gas after decomposition, which is introduced burner, to burn, and the high-temperature flue gas after burning is arranged by flue
To flue gas set, heat exchange is carried out by heat exchanger and hot water jacket；S3：Water in hot water jacket will after carrying out heat exchange in step s 2
Heat is passed in drying chamber and is heated to the rubbish in it, accelerates rate of drying and drying effect；Flue gas, which is sleeved on, is filled with high-temperature flue gas
The minimum temperature lower limit in pyrolytic tank is ensured by heat transfer afterwards；S4：Flue gas set in flue gas eventually by smoke eliminator after
It is discharged.Such structure and its method is heated up by the water in hot water jacket under heat exchange effect, and heat is incoming dry
The rubbish in it is heated in dry tank, be conducive to accelerate rate of drying and increases drying effect, is that the pyrolysis of pyrolytic tank expends more
Few heat, meanwhile, flue gas is sleeved on be filled with high-temperature flue gas after minimum temperature lower limit in pyrolytic tank, effectively profit ensured by heat transfer
With the heat after burning, energy consumption is advantageously reduced, which is extremely used in the burning disposal of rubbish, especially suitable for small-sized rubbish
The burning of rubbish；
Holding vessel is equipped between pyrolytic tank and burner, in this way can be insufficient in the flue gas come out from pyrolytic tank, first
Flue gases are enough burns again for storage etc.；
In the combustion process of step S2, by combustion supporting inlets be passed through one kind in air, natural gas, oven gas, pure oxygen, coal dust or
A variety of combination, wherein fuel completely burned in flue gas can be made by being passed through pure oxygen, can provide higher temperature and more clean discharge
Flue gas.
