Rubbish oversize epidemic situation comparison is fluffy, easily wind, and in cracking process volume can continuous polycondensation become smaller, eventually become crack charcoal
Grain or powder, performance change are very big.If conveying is relatively difficult, and is difficult to improve treating capacity simultaneously using single pushing equipment
Guarantee lytic effect.And by using house refuse oversize processing method of the present invention, screen residue of waste leads in feeding mechanism
Vertical pusher and the collaboration charging of horizontal pusher are crossed, powder feeding efficiency and inlet amount can be obviously improved.Rubbish enters cracking
After furnace inner cylinder, the helical blade width of spiral push device is gradually reduced along pyrolysis furnace difference section, can be further improved
The conveying of rubbish and lytic effect in pyrolysis furnace.
According to some embodiments of the present invention, the average grain diameter of above-mentioned screen residue of waste is not more than 10mm, and moisture content is little
In 10wt%.Thus, it is possible to further increase the heat utilization efficiency of technique while the charging effect for further increasing rubbish.
According to some embodiments of the present invention, the temperature of above-mentioned high-temperature medium can be 700~800 DEG C, and above-mentioned low temperature is situated between
The temperature of matter can be 500~600 DEG C.High-temperature medium can provide enough heats for the cracking reaction of rubbish material as a result,
And cryogenic media still keeps higher temperature, utility value with higher.
According to some embodiments of the present invention, the time that cracking reaction carries out can be 45~90min.Including rubbish material
The common work of helical blade, shovelling plate contact heating in the heating of outer barrel cavity high temperature agent burns indirect type and inner cylinder
Under, heating effect more preferably, can be cracked sufficiently through 45~90min, obtained cracking oil gas and cracked charcoal product.According to the present invention
Specific example, cracking reaction carry out time can pass through control spiral push device rotary shaft revolving speed control rubbish material
Residence time controls in inner cylinder.
According to some embodiments of the present invention, the tapping temperature of above-mentioned cracking oil gas is 400~550 DEG C.Thus, it is possible to will
Cracking oil gas, which burns to obtain high-temperature medium to supply to inside and outside cylinder, is formed by combustion heat supplying in cavity, to further increase work
The heat utilization efficiency of skill.
According to some embodiments of the present invention, the method for processing house refuse oversize of the invention can also be wrapped further
It includes: before by the charging of house refuse oversize, house refuse oversize being dried in advance.In some embodiments
In, dry Jie withering to rubbish material can be can be used as using the cryogenic media being discharged in pyrolysis furnace cavity
Matter, the medium after drying can return in pyrolysis furnace cavity, be recycled as Secondary Air, to further increase the heat of technique
Utilization rate.
According to some embodiments of the present invention, the method for processing house refuse oversize of the invention can also be wrapped further
It includes: purified treatment is carried out at least part of above-mentioned cracking oil gas, it is for sale to obtain cracking gas and cracked oil storage.
The method of processing house refuse oversize according to an embodiment of the present invention, by feeding mechanism by feeding warehouse to
Processing rubbish, which is supplied into pyrolysis furnace, carries out cracking processing, and the feeding mechanism is using vertical pusher and the collaboration pair of horizontal pusher
Rubbish to be processed is fed, and the powder feeding efficiency and inlet amount of rubbish can be significantly improved, and suitable for processing status complexity, is difficult to
The house refuse oversize (such as house refuse oversize that is fluffy, easily winding) of charging.Rubbish to be processed enters in pyrolysis furnace
After cylinder, to discharging end motion under the push of spiral push device, and it is completed at the same time cracking, obtains cracking oil gas and cracking
Charcoal.Inventors have found that with garbage cracking react progress, rubbish material successively pass through the initial segment, polycondensation section, cracking section and
Volume during stable section gradually tapers up, and is finally changed into particle or powdered cracking charcoal.Based on this feature, the present invention
The width of helical blade pyrolysis furnace difference section is gradually reduced in used spiral push device, so as to significantly improve rubbish
Rubbish keeps rubbish conveying speed more controllable in transfer efficiency, and the revolving speed by controlling augers rotary shaft can be effective
Residence time of the rubbish in pyrolysis furnace is controlled, to control the progress of cracking reaction.On the other hand, heat needed for garbage cracking
Offer of mainly being burnt in pyrolysis furnace outer barrel by high-temperature medium is provided, it is possible thereby to keep the temperature in inner cylinder relative constant, is split
The temperature control of solution reaction is more simple.Further, the cracking oil gas and cracking charcoal that garbage cracking obtains are by discharging mechanism
Corresponding outlet discharge, cracking oil gas, which can also return to burn in outer barrel, provides heat for cracking reaction.In summary, of the invention
Processing house refuse oversize method by using improved feeding mechanism and pyrolysis furnace, garbage feeding efficiency, cracking effect
Rate is significantly improved with heat utilization efficiency, has significant environmental benefit and economic benefit.
