discharged transfer roller 26b and is arranged between impact separator 26 and the second storage tanks 30.Such minimizing sorting unit 20 in use, by the first heavy-duty machine 12 gripping and when being delivered to the rear end of the first holding tank 10, the first heavy-duty machine 12 unclamps gripping arm or clamping pliers, waste is delivered to strip type crusher 23 from cast hopper 21 by input first transfer roller 23a, in the process of conveying, waste is through magnetic grader 22, magnetic grader 22 sorts out after acting on and being attracted by the waste comprising the metal species such as iron and steel in waste, and be delivered to the metal species such as iron and steel waste storage zone by magnetic force discharge transfer roller 22a, facilitate such follow-up scrap concrete, fully realize garbage as resource recycling.And carry out again broken at strip type crusher 23 except the waste material after the metal waste such as de-iron and steel class in strip type crusher 23, make its smaller volume, waste of being more convenient for scatters, facilitate the sorting of other follow-up classifications, then being carried by transfer transfer roller 24a drops in second conveyor 24b, be delivered in minimizing separator 24 by input second conveyor 24b again, minimizing separator 24 is generally screening plant, sandy soil and tiny this type of waste of the particle such as dust and earth leak down by it, then sandy soil and earth separation and collection functional area is delivered to by special e Foerderanlage, then lime method process is adopted to can be made into soil improvement agent or carry out turning sludge into fuel process to form the main raw material of organic fertilizer the sandy soil sorted out and earth the like waste.By soil and ash and so on waste sorting out after, remaining waste large-sized is delivered to impact separator 26 by input the 3rd transfer roller 26a, through the sorting of impact separator, stone and bottle are sorted out, the stone sorted out and bottle are delivered to stone bottle prospective region by specifying transfer mechanism, these stones and bottle as material of construction main raw material, also can carry out landfill.Waste after impact sorting completes the operation of minimizing and sorting, prepares to enter subsequent processing.Can also be drop between transfer roller 24b and minimizing separator 24 second to be also provided with lightweight separation system in addition, it comprises lightweight sorting casing 25c and sorting gas blower 25, sorting blower fan 25 is to the waste material blowing fallen from the second input transfer roller 24b, by plastics, paper and other lighter flammable materials are discharged transfer roller 25a from the side contrary with sorting gas blower 25 of lightweight sorting casing 25c by foreign matter and are delivered to paper waste gathering region, these paper wastes can reclaim and manufacture, realize waste energy regeneration further and repeat recycling.Like this, adopt waste sorting of the present invention and generating tail gas recycle reutilization system, total treatment capacity: first 300 tons/day of separation operation, the recycling of about 40-45% is realized by mechanical sorting operation, recycle 130 tons of/day combustiblematerialss, waste water: 40 tons of/day recyclings of about 10-15%, mud soil sand: 54 tons of/day recyclings of about 15-20%, organism: 68 tons of/day recyclings of about 20-25%, other metals: 3 tons of/day recyclings of about 1-3%, landfill material: 5 tons of/day sortings that stone tiles glass is about 1-5% are reclaimed.Waste thermal value after sorting: biological fuel gas every cube combustion heat value is 4500 kilocalorie to 5000 kilocalories.Effective saving energy, make full use of rubbish material generate energy and the energy, salvage value is high.In addition, can also be that the second side, storage tanks 30 upper end is provided with the second crusher 32, the fragmentation transferred by the second lifting machine 31 and the waste supplying of sorting are again supplied to the second storage tanks 30 to the second crusher 32 by the second crusher 32 fragmentation and use, its effect carries out fragmentation to make the material size in the second holding tank 30 less, facilitate the process of follow-up generation synthetic gas more unobstructed, synthetic gas production efficiency is higher, and efficiency of combustion is high.Certainly can also be that the first storage tanks 12 upper end is
