Description
Technical field
The utility model relates to a kind of waste incineration pyrolysis installation, is specially a kind of refuse pyrolysis plant preventing bioxin from generating.
Background technology
Waste incineration pyrolysis is a kind of high-temperature hot chemical treatment method, and the combustible component in rubbish reacts with the oxygen in air in incinerator, is converted into high-temperature gas and solid residue.Waste incineration pyrolytic process produces a large amount of heat energy, volume can reduce 80%-90%, the composition structure of harmful solid waste can be destroyed, kill pathogen, reach the object that toxin expelling is removed the evil, there is the feature of decrement, harmless, resource, be one of garbage disposal means of extensively adopting of current developed country, to plough in great shortage country in Japan etc., waste incineration pyrolysis processing ratio reaches 65-80%.But conventional garbage burns pyrolysis treatment device and has the following disadvantages:
One is that conventional garbage burns the burning process of pyrolysis installation and will generate a large amount of bioxin.Bioxin intractability is large, and disposal cost is high.Although Dui dioxins materials research in recent years and understanding deepen continuously, controlled and strict incineration flue gas technique by incinerator " 3T " technically, can the emission control of Shi dioxins materials under strict standard, but considerably increase one-time investment and operating cost, gas cleaning removes dioxins materials and also there is secondary pollution.
Two be conventional garbage burn pyrolysis installation need supplementary energy many, and waste incineration itself generation heat utilize usefulness not high enough, cause waste incineration cost high.Further, conventional garbage incinerator has higher requirement to refuse thermal value and moisture.CJ/T 118-2000 specifies, " enter the average annual moisture of stove house refuse and should not be greater than 50%, average annual content of ashes should not be greater than 30%, and average annual low heat valve should not be less than 4.18MJ/kg ".For ensureing smooth combustion, " domestic refuse treatment project technical regulation " specifies, " incinerator answers collocation point ignition combustor and auxiliary burner ", needs the auxiliary fuel of at substantial.
Three is existing incinerator complex structures, and manufacturing cost is large, and buy and use one-time investment large, the project construction occupied fund cycle is long.Build mark 142-2009 regulation, " newly-built grate furnace incineration plant main equipment and system can by higher than 500,000 yuan/(t/d) controls based on the investment estimate entering blowing mouth; The investment estimate that grate furnace incineration plant main equipment all domesticizes can by not higher than 400,000 yuan/(t/d) control; The indices for investment estimate of newly-built fluid bed furnace incineration plant can by not higher than 350,000 yuan/(t/d) control ".To this, advanced economy basis and the powerful investment capacity is not had to be difficult to build up.
Conventional garbage burns the deficiency of pyrolysis installation, significantly limit waste incineration pyrolysis applying in China, especially in the application of small and medium-sized cities.
Although some domestic entity and individual are devoted to the research of waste incineration pyrolysis installation always, try hard to overcome existing deficiency.Such as document CN201410085904.9, discloses on the basis of conventional garbage electricity generation system, has added pretreatment system, flue gas treating system, and percolation liquid treating system, to reduce the generation of bioxin combustible organic; Document CN201320090207.3, discloses and uses oxygen-enriched combusting equipment and secondary air system, to ensure incinerator waste gas burning temperature to greatest extent, make the flow-disturbing being conducive to secondary combustion chamber, extend in the secondary combustion chamber time of staying, to decompose bioxin.But these technology one-time investments are large, and operating cost is high, and effect is undesirable, and practicality is not strong.
