Description
Technical field
The utility model is related to incineration treatment of garbage technical field, can be reduced more particularly, to one kind in Refuse Incineration Process
The device of unburned thing discharge capacity；The utility model further relates to a kind of to reduce unburned thing discharge capacity in Refuse Incineration Process
Waste incineration processing system.
Background technology
At present, domestic rubbish annual production reaches 1,000,000,000 tons, wherein about 400,000,000 tons of house refuse, and the storage of Chinese rubbish is
More than 8,000,000,000 tons.There is data to suggest that：The city of China more than 2/3rds is surrounded by rubbish, and the city of a quarter is not closed
Suitable place heap garbage, rubbish stores up accumulative 800,000 mu of appropriation of land.Chinese 40,000 small towns, nearly 600,000 administrative villages are often produced per year
Raw house refuse is more than 2.8 hundred million tons, in most of rural area and Small Urban, largely there is rubbish and throws out the behavior of leaving about without care, not only
Rare soil has been occupied, environment has been polluted, and seriously jeopardize the health of the mankind.
The processing of Chinese rubbish is still based on landfill, and landfill method is simply extensive, simply displaced and stains ground.And rubbish is passed through
The burning disposal of modernization is crossed, volume can typically reduce 80%~90%, while various pathogen can be eliminated, by harmful substance
Harmless object is converted into, the utilization of recycling can also be realized, waste incineration is to realize garbage decrement, at innoxious and recycling
One of main path of reason.
Waste incineration can be increasingly becoming one of main path of garbage disposal, using machinery more than the existing waste incineration of China
Formula waste incinerator, for example, CN104613481A discloses a kind of waste incinerator.MSW heating value is relatively low.Such as part
Engineering design calorific value is in 1450kcal/kg or so.Large-scale incinerator and can be preferably with the stove of other fuel mixed combustions
House refuse is more fully hereinafter burnt, operating cost is still received, the secondary pollution to environment is smaller.However, because being received by rubbish
The factor influence such as collection and transport, in plurality of Small Urban and rural area, it is impossible to handle life rubbish using large-scale incinerator
Rubbish, also lacks the facility that rubbish is uniformly processed, some areas handle house refuse using simple waste incinerator, many extensively
Number area is still voluntarily burnt away the refuse outdoor, brings the secondary pollution to environment and occurs the hidden danger of unexpected fire, at present in agriculture
The waste incinerator generally existing that village and Small Urban are used burns insufficient, not exclusively, big for environment pollution in combustion process,
The problems such as it is difficult to continue to use.
Burn insufficient, not exclusively, need to largely use auxiliary fuel, input and operating cost are higher, it is difficult to persistently make
With.For simple incinerator, in combustion, imperfect combustion, great Liang Wei easily occur for the house refuse of low heat value
Combustible substance rises with flame and burning gases, due to there is substantial amounts of bioxin predecessor, institute in unburned part
With in burning and gas-exhausting generate the very strong bioxin of toxicity, be discharged into air, in addition, the discharge capacity of other pollutants also compared with
It is many.

It is difficult to leak in external environment condition, is conducive to keeping the cleaning of working environment.
Because the calorific value of rubbish is generally relatively low, and fluctuation is larger, needs the auxiliary combustion by combustor 104 combustion-supporting sometimes, this
When, burned if excessive cold air enters in main stove 1, the temperature in stove can be reduced, make combustion position be difficult to reach normally.Set
Oxygen system 106, when burning difficult, by being passed through oxygen into the main stove 1 of burning, reduces the inlet of cold air, can be rapid
Improve combustion position, save Fuel Consumption, while reducing the outer row of pollutant.
In combustion, incomplete combustion easily occurs for the rubbish of low heat value, a large amount of unburnts with flame with
And burning gases rise, and due to there is substantial amounts of bioxin predecessor in unburned part, toxicity is generated in burning and gas-exhausting
Very strong bioxin.Set and burn secondary stove, containing not sufficiently combusted carbon monoxide, hydrocarbon, carbonaceous organic material cigarette
Gas enters to burn to burn away in secondary stove 2；Burning secondary stove 2 includes at least one combustion chamber 201, with helping that combustion chamber 201 is connected
Combustion engine structure 3；When burning the flue-gas temperature in secondary stove 2 higher than setting value, combustion-supporting mechanism 3 is inoperative；Secondary stove 2 is burned when entering
When flue-gas temperature is less than setting value, combustion-supporting mechanism 3, which is opened, makes the temperature in the secondary stove 2 of burning reach setting value, makes ignition temperature control
System is within preferably temperature range, it is to avoid the generation of bioxin.Such as setting value is that unburned thing can be made fully to burn and energy
Suppress more than 850 DEG C of bioxin generation.
Because the calorific value of rubbish is generally relatively low, moisture content fluctuation is big, and feeding conveyor structure 604 is provided with heating chamber 607, utilizes
Fume afterheat evaporates moisture, reduces moisture content, so as to be more beneficial for burning to intending entering the rubbish heating for burning main stove 1.Heating
The air that room 607 is also transferred thermal energy in the air in casing 606, casing 606, which enters, to be burned in main stove 1 so that is entered and is burnt
The air burnt in main stove 1 is preheated, so as to improve the combustion position burned in main stove 1.
Obviously, the utility model is not limited to above preferred embodiment, can also be in the utility model claim and explanation
In the spirit that book is limited, the conversion and improvement of diversified forms are carried out, same technical problem can be solved, and obtain expected technology
Effect, therefore do not repeat.One of ordinary skill in the art can from the utility model disclosure directly or associate it is all
Scheme, as long as within the spirit that claim is limited, falling within protection domain of the present utility model.
