Description
Technical field
The utility model relates to a kind of waste incineration pyrolysis treatment device, is specially a kind of rubbish and walks crosswise screening whirlwind mixed combustion pyrolysis installation.
Background technology
Refuse pyrolysis is the garbage disposal means that developed country extensively adopts, and in the country that the arable lands such as Japan are in great shortage, waste incineration pyrolysis processing ratio reaches 65-80%.But conventional garbage burns pyrolysis treatment device and has the following disadvantages:
One is, conventional garbage burns pyrolysis installation and can not realize sieving rubbish burning process is simultaneously automatic, can not carry out the progressive pyrolysis of classification locellus, the further pyrolysis of gaseous substance except cinder insufficient, easy generation pyrolysis blocks, and affects the environment-friendly garbage pyrolysis preventing bioxin from generating.In conventional garbage mixture, containing the Multiple components such as life organic matter and plastics, glass, ceramics, metal, cement block, before burning, classification intractability is large, and cost is high, adopts garbage mixture directly to enter stove more burn so.But garbage mixture does not sieve and directly enters stove to burn the problem brought be that incineration temperature is difficult to simultaneous adaptation and easily produces the organic waste of bioxin and easily cause the inorganic refuse blocking, affect burning state and deslagging.The retardance of blocking up of burning process, not only increase maintenance cost, and burning state is changed, the control that leading portion suppresses bioxin to generate is burned in impact, increase difficulty and the expense of follow-up bioxin process, add follow-up gas cleaning and remove the possibility that dioxins materials causes secondary pollution.
Two are, existing incinerator technological process mechanism unit is lateral extension, the gaseous substance of easy upwards ascension such as moisture, flue gas etc. that refuse pyrolysis process produces, need the air-introduced machine of relatively high power just can make it transverse shifting and enter next step process, especially easily producing that the organic matter of bioxin is tentatively pyrogenous origin can hot gas, Secondary Air burns further again, and process power consumption is high, and process is difficult to fully, and effect is undesirable; And mechanism unit lateral extension, floor space is large, and one-time investment is large.Build mark 142-2009 regulation, " newly-built grate furnace incineration plant main equipment and the investment estimate of system based on import can by higher than 500,000 yuan/(t/d) controls; 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.
Three are, 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/T118-2000 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.
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, in the generation reducing bioxin presoma, done good try; Document CN201320090207.3, disclose and use 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, in decomposition bioxin, achieve certain effect.But these technology all can not carry out automatic sieving to rubbish in pyrolysis, the progressive pyrolysis of locellus of can not classifying, generate with bioxin to prevent from blocking, practicality is not strong, and pyrolysis benefit is not high.
Utility model content
The purpose of this utility model is exactly for above-mentioned deficiency, a kind of rubbish is provided to walk crosswise screening whirlwind mixed combustion pyrolysis installation, it can realize sieving rubbish burning process is simultaneously automatic, carry out the progressive pyrolysis of classification locellus, prevent blocking of pyrolytic process, especially secondary burning pyrolysis is energy-conservation, abundant, can realize better preventing bioxin from generating environmental protection pyrolysis, and space availability ratio is high, take up an area few, can construction investment be reduced, reduce pyrolysis energy consumption, operation expense is low, and the effect efficiency of garbage disposal is better.
For achieving the above object, the technical solution of the utility model is, screening whirlwind mixed combustion pyrolysis installation walked crosswise by this rubbish, comprise the cavity with garbage inlet, described garbage inlet is arranged on sidewall or the shelves wall of cavity, the screening mechanism making rubbish walk crosswise screening pyrolysis is provided with at the side-lower of described garbage inlet, solid phase pyrolysis chamber is provided with in the below of described screening mechanism, vapour-phase pyrolysis room is provided with above described screening mechanism, the bottom of this vapour-phase pyrolysis room has DL lumen, to calm the anger all chambeies, the upper and lower side of described DL lumen has opening, described DL lumen is communicated with all chambeies of calming the anger by the passage of calming the anger of its perisporium, described all chambeies of calming the anger are connected with hot-air conveying mechanism.
Described screening mechanism can have some lateral separations and arrange homodromous sieve roller, has sieve apart from (interval), can arrange hot-air conveying mechanism at described screening mechanism between each sieve roller,
