Additionally, the present invention also provides a kind of garbage disposal side using above-mentioned solid refuse innocuity disposal system simultaneously Method, process step is:Through light plastic, just screening device selects plastics to solid waste, then enters closed baking by feed device Dry container and Horizontal type rotatable classifying screen are dried and sorted, the fine grained selected, then sub-elect secondary to light plastic first Material is directly entered organic fertilizer fermentation pond and is fermented, and other particulate materials for sub-electing are divided metal by the magnetic separation of metal recovery machine Through crushing the broken re-grading of integrated machine for sorting after picking, inorganic matter and glass disintegrating slag after classification can be as the secondary profits of construction material With, plastic bottle fragmentation and product plastics recycling, after classifying screen sorting oversize in classifying screen discharge end by garbage collector The burning Indoor Combustion gasification of combustion gasification stove is sent into, hot blast is drying institute through heat supply pipeline feeding drying closed container after gasification With;Polybag and light plastic are extracted out to enter after plastic collection room is processed with hot waste gas by air exhauster and recycled, and dry waste gas Then enter catalytic converter harmless emission.
Preferably, in above-mentioned solid refuse harmless treatment processing method, solid waste enters light plastic just screening device Before, lifted by grab bucket, rubbish is put into recovering hopper, dropped down onto under rubbish in spiral reamer case at the spiral reamer of feed side, block In the grid that shape thing and plastic packaging bag are fallen into below spiral reamer by hanging breaking, broken rubbish, and then drop on dehydration and vibration sieve; And wooden unit and bulk materials then float on spiral reamer and broken rubbish, push forward at aniseed guiding gutter, automatic outflow, Bulk and plank is avoided to enter next procedure.
Preferably, in above-mentioned solid refuse harmless treatment processing method, at the beginning of solid refuse is displaced downwardly to light plastic When in screening device in rotor, the light plastic of rotation is smoked by air exhauster and enters air draft pipe, enters back into plastic collection Indoor Collection utilization.
Operation principle of the invention is:
Main part technique of the invention is light plastic primary election → drying, sorting → gasification, wherein sorting is by classifying screen Segmentation is sorted step by step, and the fine grained material for sub-electing is directly entered the fermentation of organic fertilizer fermentation pond, and other particulate materials for sub-electing are led to Cross and re-grading crushed after metal is sorted in magnetic separation, inorganic matter and glass disintegrating slag after classification can as the secondary utilization of construction material, Waste plastic bag and plastic bottle fragmentation and product plastics recycling, oversize is clothes, bulk paper, footwear after classifying screen sorting The combustible such as cap and branch is gasified in classifying screen discharge end by the burning Indoor Combustion of garbage collector feeding gasification furnace, after gasification Through heat supply pipeline for drying is used, polybag and light plastic enter plastic collection to hot blast by air exhauster with the secondary extraction of hot waste gas Recycled after the treatment of room, drying waste gas then enters catalytic converter harmless emission.
The Advantageous Effects of technical solution of the present invention are:
1st, in structure, the contained classifying screen outside of the present invention is the drying closed container of 300 DEG C or so of temperature, and rubbish is in sorting It is oven-dried simultaneously, compact conformation;Wherein classifying screen is sorted for segmentation step by step, and different size and different types of is sub-elected successively Particulate material, classifies and is respectively processed, and the combustible material that bulk cannot be sorted then is gasified, and gasification hot gas is returned and is used for Drying, drying waste gas then enters catalytic converter harmless emission.Thus, production technology is optimized, topology layout is more reasonable, rubbish Rubbish high treating effect, reduces production equipment and environmental protection equipment investment, and energy saving saves land area and environmentally friendly, substantially in fact Show innoxious.
2nd, in structure, rubbish dry classifying screen while, polybag and dab plastics by after primary election again with baking Xeothermic air-flow is pumped into plastic collection room and reclaims by air exhauster, it is to avoid pollution of the dioxin to air in waste gas.
3rd, in structure, just the compass screen surface of screening device classifying screen is to be obliquely installed to light plastic of the present invention, in screening process, Rubbish can run downwards automatically by self gravitation, at the same by moisture removal in rubbish, thus power is eliminated, save energy Source, production and application low cost.
4th, in structure, spiral reamer case is set up, big small packages and block hanging breaking grid can be uniformly scattered in On, and then drop in the first screening device of plastics, so that light plastic in rubbish is extracted out, and wooden unit and bulk materials then float Above spiral reamer and broken rubbish, push forward at aniseed guiding gutter, automatic outflow, in the case where equipment and operation are torn up in reduction, Bulk and plank is avoided to enter next procedure, to result in blockage.
5th, in structure, in structure, light plastic just screening device is set up before feed device, when rubbish is displaced downwardly to rotational circle When in cylinder, the light plastic of rotation is smoked, and by entering plastic collection room in exhaust column, light plastic is herein through preliminary point Choosing, to classifying screen in it is secondary be sorted, eventually enter into plastic collection room and be recycled.So as in avoiding conventional process Plastics gasify pollution of the composition dioxin to air, realize it is innoxious, therefore beneficial to environmental protection.
6th, in structure, just screening device is that horizontal square crossing is set relative to feed device to light plastic, then further Shorten the longitudinal length of equipment, more compact structure.
