The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Chicken and duck bone, fishbone, throwaway chopsticks, cutlery box, dish leaf, polybag, napkin paper even small electric apparatus etc. are arranged, very bad classification in the house refuse.Be that garbage disposal is the most thorny for non-classified rubbish.The classification though medical waste is not difficult has various viruses, bacterium in this class rubbish, so bad recycling.
The present invention is directed to this class rubbish, designed a cover processing method, this method is to utilize means such as fragmentation, dehydration, selection by winnowing, flotation with above-mentioned house refuse, medical garbage sorting, to realize recycling.
As shown in Figure 1, the embodiment of the invention provides a kind of waste disposal method, and described method comprises:
Step S101: with refuse breaking;
Step S102: with the garbage dewatering after the fragmentation;
Step S103: to the dehydration after rubbish carry out selection by winnowing, described rubbish is divided into: the anharmonic ratio heavy substance, in than heavy substance, gently than heavy substance, dust;
Step S104: with in described than heavy substance with gently put into solution respectively than heavy substance and carry out flotation, so that different material is wherein further separated.
The embodiment of the invention also comprise with described selection by winnowing come out in than heavy substance and the step of gently milling respectively than heavy substance, as the alternative steps of step S104, or carry out simultaneously with step S104.
With refuse breaking, be in order to make the Bottle ﹠ Can fragmentation in the rubbish, to make the liquid that may exist wherein trickle out, and the rubbish that wraps in the polybag is come out among the step S101, the refuse breaking of bulk is become roughly piece uniformly.In thermal dehydration is subsequently handled, can make all rubbish in the same processing time like this, be dewatered to same degree.Refuse breaking can be adopted an impact crusher.Impact crusher can flow out the liquid substance that may exist in the container, so that processed becomes fritter with refuse breaking simultaneously container fragmentations such as the vial in the rubbish, plastic bottle.Broken rubbish also can adopt one to smash machine and a pulper.Smashing the machine main purpose is with container fragmentations such as vial, plastic bottles, and the liquid substance that may exist in the container is flowed out; Pulper can be cut the rubbish that makes wherein with packaging bag, polybag and come out, and relatively large rubbish is blended.Broken rubbish can also only adopt a pulper.
Among the step S102 with the garbage dewatering after the fragmentation, refer to contain in the rubbish material of moisture content, as dish leaf, bone, the food that abandons, and some containers in liquid, at high temperature or make it lose former water content under the heated drying air.The degree of dehydration should reach 50% to 80%, and preferred degree of dehydration should reach about 60%.Degree of dehydration percentage refers to that certain material contains removed moisture part in the water inventory in the rubbish.Dehydration one selection by winnowing that can make things convenient for subsequently, two dewater can kill bacterium and virus.The environment that dehydration back bacterium multiplies is again loss, so after the sterilization, bacterium is difficult for regeneration.
Dehydration can be adopted various dewaterings of the prior art, but preferably adopts heat treated way to make garbage dewatering.For example can adopt a kind of or several combination arbitrarily in Electric heating, heated drying air mode of heating, waste heat of plant or the waste heat mode, also can use drying tower.Wherein, Electric heating can comprise: a kind of or several combination arbitrarily in microwave heating, resistance wire mode of heating, the lamp heated mode.Adopt heat treatment to make the benefit of garbage dewatering be, in heated baking, also can make the thorough sterilization of rubbish.
Paper may be the most incendive material in house refuse.Paper generally will burn more than 400 ℃, so the heating-up temperature in when dehydration generally can be controlled in below 400 ℃.For energy-conservation consideration, suggestion is made as between 110 ℃ to 170 ℃ is advisable in addition.But for the consideration of acceleration dehydration, or when handling medical waste, need thorough kill bacteria and viral consideration, temperature can be located at higher temperature, between 170 ℃ to 400 ℃.
Step S103 to the dehydration after rubbish carry out selection by winnowing, be with blower fan dried rubbish to be dispelled, drop on the most nearby may be the heavier materials of proportion such as stone, glass, metal derby; Secondly may be to compare heavy substance in unit of plastic, wooden unit, batten, the bone etc.; In lighter than metal, stone than heavy substance, but heavier than dish leaf dry after paper, cloth, polybag, the dehydration, plastic foam etc.; May be that dish leaf dry after papery material, cloth metallic substance, polybag, the dehydration, plastic foam etc. are gently than heavy substance again; Descend slowly and lightly farthest may be a little dust.
Material after the selection by winnowing is divided into the anharmonic ratio heavy substance, as stone, glass, metal derby etc.; In than heavy substance, as plastics, wood materials, bone etc.; Gently than heavy substance, as paper, cloth, polybag, dry dish leaf etc. and dust four classes.Certainly if desired, also can adopt more sophisticated category of wind selection method, can be divided into the material of the above different specific weight of four classes.Can first rough segmentation become four class materials, and then respectively to dividing four good class materials, selection by winnowing again is in the hope of telling the different material of segmentation.This selection by winnowing also can repeat repeatedly, but considers best selection by winnowing once or twice from cost and practical feasibility.
As shown in Figure 2, centering is carried out flotation than heavy substance and can further be comprised and use two steps that floation tank carries out flotation among the step S104:
Step S1141: flotation for the first time, will be placed in the solution of first floation tank than heavy substance in described, stagnate a period of time after, salvage float over the solution upper strata in compare heavy substance;

Step S1242: flotation for the second time, with salvage described float over the solution upper strata in be placed in the solution of first floation tank than heavy substance, stagnate a period of time after, salvage respectively float over the solution upper strata and be sunken to the solution bottom in compare heavy substance.
With in place water than heavy substance, wood materials, bone etc. can be bubbled through the water column, plastic substance can be sunken to the bottom rapidly.The sorting substances that wood materials, bone etc. is kept afloat is come out.
Can act as a fuel in order to compost for the wood materials that flotates, bone etc., or can directly return and spill the land for growing field crops, allow its natural degradation.
For demersal plastic substance after the flotation, after pulling out, can directly send into pyrolysis furnace, be reduced into oil.Or manufacture molding product processed through extrusion molding, or be used as plastic raw materials.
In a preferred embodiment of the present invention, after drying, selection by winnowing, the compounding substances of centering proportion carries out a flotation.Middle proportion rubbish is placed water, in 30 seconds to 10 minute, the wood materials of keeping afloat, bone etc. are pulled out.Then demersal plastics are pulled out.After the flotation, can be according to situation with the plastic substance natural air drying.But to pulling natural air dryings such as the wood materials that comes and bone out, but also second dehydration shown in the step S105 among Fig. 8, utilizes or the back utilization of milling then according to need or directly.Centering carries out also it to be milled before the flotation than heavy substance.
In another preferred embodiment of the present invention, after centering is finished than heavy substance flotation, the plastic substance that sorts out directly can be sent into pyrolysis furnace, be reduced into oil.Or processing and manufacturing becomes plastic raw materials.
No matter be to grind preceding or grind after the plastic substance that flotates can dewater for the second time.Natural air drying gets final product.Need second dehydration for the wood materials that flotates, bone etc., can decide as circumstances require.If directly as compost, be thrown into methane-generating pit, second dehydration more then.If preferably carry out second dehydration as fuel, even consider its shape of claying into power, conveniently to spray into the burner hearth burning.
In another embodiment of the present invention, after centering is than heavy substance flotation, the wood materials that floatingly selects, bone etc. are dewatered again.Wood materials, bone after the dehydration etc. are carried out vibration screening one time, bone etc. is separated with wood materials.The wood materials of telling can be used for papermaking, and bone etc. can be used for compost, makes biogas etc.
In a preferred embodiment of the present invention, centering is carried out double flotation than heavy substance.When carrying out double floating operation, should with medium put into water than heavy substance after, be that xyloid material, bone etc. are pulled out as early as possible with the material of bubbling through the water column.The time of pulling out should be at 30 seconds in 10 minutes.Because bone etc. also can sink under water after having suctioned moisture content, be mixed in the plastic substance.
After the flotation first time, with wood materials, bone etc. be sunken to after separating plastic at the bottom of the pond comes out, the compounding substances of wood materials and bone etc. is carried out a flotation again.Utilize bone to suction the characteristics that moisture content sinks afterwards, the wood materials of bubbling through the water column is separated with bone material.During flotation for the second time, soak time can be longer, generally should be more than 10 minutes.After treating that bone material sinks, again the wood materials of keeping afloat is pulled out.To sink to water-bed bone material then picks up.
The wood materials of separating is good paper making raw material.Organic substances such as bone are compost, the good material of making biogas.
As shown in Figure 5, can further comprise two steps that floation tank carries out flotation of use to gently carrying out flotation than heavy substance among the step S104:
Step S1341: flotation for the first time, gently be placed in the solution of first floation tank than heavy substance described, stagnate a period of time after, salvaging float over the solution top layer gently than heavy substance;
Step S1342: flotation for the second time, with describedly gently being placed in the solution of second floation tank than heavy substance of salvaging, stagnate a period of time after, salvaging float over the solution top layer gently than heavy substance.
Whenever once salvage float over the solution top layer gently than after the heavy substance, can once salvage in the floation tank remaining gently than heavy substance.
As shown in Figure 7, among the step S1143, after carrying out N flotation for the first time and flotation for the second time (N is more than or equal to 2 times), salvage in described first floation tank remainingly gently than heavy substance, and salvage in described second floation tank remaining gently than heavy substance.So more help to raise the efficiency.
As shown in Figure 6, can further comprise step that floation tank carries out flotation of use to gently carrying out flotation than heavy substance among the step S104:
Step S1441: flotation for the first time, gently be placed in the solution of first floation tank than heavy substance described, stagnate a period of time after, salvage respectively float over below solution top layer and the top layer gently than heavy substance;
Step S1442: flotation for the second time, describedly float over the light of solution top layer and be placed in the solution of first floation tank than heavy substance what salvage, stagnate a period of time after, salvage respectively float over solution top layer and top layer following gently than heavy substance.
In another preferred embodiment of the present invention, than heavy substance, also can carry out flotation for gently.Flotation can be once, also can be twice, or more than twice, preferably twice.Gently than mainly being constituted by polybag, paper, cloth, little plastic sheet, plastic foam etc. in the heavy substance.During flotation for the first time, will all gently pour in the floation tank than heavy substance.After will be gently scattering than heavy substance, within general 30 seconds, the material that is about to keep afloat is pulled out.Generally speaking, moulding sector-meeting for a short time sinks under water rapidly; Paper, polybag, cloth, plastic foam etc. can be bubbled through the water column.After the paper of bubbling through the water column, polybag, cloth, plastic foam etc. are pulled out, the plastic sheet at the bottom of the pond is pulled out, or several times soak gently than after the heavy substance, the disposable plastic sheet that will be sunken at the bottom of the pond is pulled out again.
After the flotation for the first time, can carry out the flotation second time at once.Can in same floation tank, carry out, also can in another floation tank, carry out.Preferably in another floation tank, carry out.If in same floation tank, carry out, need in advance demersal plastic sheet to be pulled out.
