Description
Technical field
The present invention relates to incineration treatment of garbage technical field, can reduce unburned in Refuse Incineration Process more particularly, to one kind
Burn method, the device of thing discharge capacity；The invention further relates to a kind of rubbish that can reduce unburned thing discharge capacity in Refuse Incineration Process
Rubbish burning 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 800,000 mu of accumulative appropriation of land.Chinese 40,000 small towns, nearly 600,000 administrative villages are often produced per year
, in most of rural area and Small Urban, there is rubbish in a large number and throw out the behavior of leaving about without care, not only in raw house refuse more than 2.8 hundred million tons
Rare soil is occupied, environment has been polluted, and has seriously jeopardized the health of the mankind.
The process of Chinese rubbish is still based on landfill, and landfill method is simply extensive, simply displaced and stains ground.And rubbish Jing
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 resource can also be realized, waste incineration is realized at garbage decrement, innoxious and resource
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 incinerator, for example, CN104613481A discloses a kind of 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 less.However, because being received by rubbish
The factor such as collection and transport affects, in plurality of Small Urban and rural area, it is impossible to process life rubbish using large-scale incinerator
Rubbish, also extensively lacks the facility being uniformly processed to rubbish, and some areas process house refuse using simple waste incinerator, many
Number area is still voluntarily burnt away the refuse outdoor, brings the secondary pollution to environment and the hidden danger of unexpected fire occurs, at present in agriculture
The incinerator generally existing that village and Small Urban use burns insufficient, not exclusively, big for environment pollution in combustion process,
The problems such as it is difficult to persistently to use.
Burn insufficient, not exclusively, need in a large number use auxiliary fuel, input and operating cost are higher, it is difficult to persistently make

Processing system is burnt also with being connected with body of heater 101, for detecting the sensor of temperature in burner hearth 102, sensor and air-introduced machine 8
Control system and the electric signal connection of control valve.
Rubbish Jing feed conveying devices 6 are delivered in the main stove 1 of burning, are sequentially passed through on traveling-grate stoker 103 and are dried,
Fire, burning, burning cinder stage, lime-ash Jing tapping mechanisms 107 discharge out of the furnace.Flue gas and imperfect combustion thing after burning is entered and burned
Secondary stove 2, the flue gas containing not sufficiently combusted carbon monoxide, hydrocarbon, carbonaceous organic material is burning continuation combustion in secondary stove 2
Burn；Burning secondary stove 2 includes at least one combustion chamber 201, the combustion-supporting mechanism 3 being connected with combustion chamber 201；When in the secondary stove 2 of burning
When flue-gas temperature is higher than setting value, combustion-supporting mechanism 3 is inoperative；When the flue-gas temperature for burning secondary stove 2 is entered less than setting value, help
Combustion engine structure 3 is opened makes the temperature in burning pair stove 2 reach setting value, such as setting value for unburned thing can be made fully to burn and
More than 850 DEG C of bioxin generation can be suppressed.Because the surface temperature of the accumulation of heat deflector group 4 in combustion chamber 201 it is higher, when containing
The smoke contacts of unburned thing can burn rapidly to after accumulation of heat deflector 203.The lime-ash of combustion chamber deposit falls into ash discharge mechanism
In 204, Jing ash discharges mechanism 204 discharges.Burn that flue gas that secondary stove 2 discharges is cooled down Jing waste heat boiler 5, Jing draws after the dedusting of deduster 7
Blower fan 8 is discharged.In combustion process, in addition to air-introduced machine outlet is for malleation, burner hearth 102 and other flue gas systems are negative pressure, make flue gas
It is difficult to leak in external environment condition, is conducive to keeping the cleaning of working environment.
Because the calorific value of rubbish it is generally relatively low, and fluctuate it is larger, need the auxiliary combustion by combustor 104 combustion-supporting sometimes, this
When, if excessive cold air is entered burning in main stove 1, the temperature in stove can be reduced, make combustion position be difficult to reach normally.Arrange
Oxygen system 106, when burning is 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, easily there is incomplete combustion in low-calorie rubbish, 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 are generated in burning and gas-exhausting
Very strong bioxin.Arrange and burn secondary stove, containing not sufficiently combusted carbon monoxide, hydrocarbon, carbonaceous organic material cigarette
Gas is entered to burn and burnt 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 it is higher than setting value to burn the flue-gas temperature in secondary stove 2, 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 opens makes the temperature in burning pair stove 2 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, water content fluctuation is big, and feeding conveyor structure 604 is provided with heating chamber 607, utilizes
Fume afterheat evaporates moisture content to intending entering the rubbish heating for burning main stove 1, moisture content is reduced, so as to be more beneficial for burning.Heating
Room 607 also transfers thermal energy to the air in casing 606, and the air in casing 606 is entered and 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.
It is clear that the invention is not restricted to above preferred embodiment, can also limit in the claims in the present invention and specification
In spiritual, the conversion and improvement of various ways are carried out, same technical problem can be solved, and obtain expected technique effect, therefore
Do not repeat.One of ordinary skill in the art can from present disclosure directly or all schemes for associating, if
Within the spirit that claim is limited, protection scope of the present invention is fallen within.
