Description

Can suppress Refuse Incineration Process produces the incinerator of unburned thing
Technical field
The present invention relates to a kind of can suppression the rubbish process such as burning domestic garbage, trade waste produces the unburned thing such as CO, Hydrocarbon and produces the incinerator of two English。
Background technology
At present, in major part rural area and Small Urban, there is rubbish in a large number and throw out the behavior of leaving about without care, the pollution of rubbish has resulted in the impact on living environment, because rural area and Small Urban extensively lack the facility that rubbish is uniformly processed, villager burns away the refuse mostly in the open voluntarily, bring the secondary pollution to environment and the hidden danger of unexpected fire occurs, the incinerator ubiquity used in rural area and Small Urban at present is difficult to clear up, burn insufficient, not exclusively, big for environment pollution in combustion process, it is difficult to the persistently problems such as use。
Rubbish is through modern burning disposal, volume generally can reduce 80%~90%, can eliminate various pathogen simultaneously, harmful substance is converted into harmless object, can also realizing the utilization of resource, waste incineration is one of main path realizing garbage decrement, innoxious and recycling treatment。
Waste incineration becomes one of main path of current garbage disposal, China's existing waste incineration many employings mechanical garbage incinerator, such as, CN104613481A discloses a kind of incinerator, the incinerator provided is lateral arrangement, being combined by some mobile units in the horizontal, described some mobile units are by a support arrangement integral support and are driven by same driving device。Effectively solve the problem that pusher dolly is stuck, make house refuse more uniformly spreading on fire grate simultaneously, improve combustion efficiency。
In prior art, most incinerators include charging aperture, feed fire grate, are positioned at the fire grate for waste incineration of burner hearth, are positioned at the burning First air air feed system of fire grate bottom, the secondary wind air feed system being positioned at furnace throat portion and slag extractor。Burn fire grate and be monolithically fabricated the siege for burning away the refuse, siege is longitudinally divided into dryer section, burning zone and after-flame section, burning fire grate entirety and be longitudinally divided into multiple burning unit, be generally 5 unit, each burning unit is made up of multiple slip fire grate segments, travelling grate sheet and fixed grate film。Rubbish pours incinerator into from charging aperture, entered by the reciprocating effect rubbish of feed fire grate and the siege in incinerator burns, dried at dryer section rubbish, dehydration, rubbish mainly burns at burning zone, rubbish through after-flame section has burnt totally, remaining slag enters slag extractor afterwards, slag extractor discharge out of the furnace。Wherein First air is sent into from the air compartment burned bottom fire grate, and secondary wind is sent into from the furnace throat portion of incinerator。Existing incinerator (industrial furnace), in the process burnt away the refuse, the bad control of ignition point, burning process controls accurate not, burns insufficient, is inevitably generated harmful gas, such as nitrogen oxides and two English etc., these harmful gass are very harmful to environment and human body。
MSW heating value is relatively low。Such as part engineering design calorific value is at about 1450kcal/kg。House refuse can more fully hereinafter be burnt by large-scale incinerator and the stove with other fuel mixed combustion preferably, and operating cost still can receive, and the secondary pollution of environment is less。But, because being affected by the factor such as refuse collection and transport, in plurality of Small Urban and rural area, it is impossible to adopt large-scale incinerator to process house refuse, it is only capable of adopting simple waste incinerator to process house refuse。Burn insufficient, not exclusively, auxiliary fuel need to be used in a large number, put into and operating cost is all higher, it is difficult to continue to use。For simple and easy incinerator, low-calorie house refuse is in combustion, very easily there is imperfect combustion, a large amount of unburnts rise along with flame and burning gases, owing to there are substantial amounts of two English predecessors in unburned part, so generating two English that toxicity is very strong in burning and gas-exhausting, it is discharged in air, additionally, the discharge capacity of other pollutant is also more。Thus exploitation substitutes the same category of device of simple waste incinerator in prior art, there is realistic meaning。
Summary of the invention
