Abstract
The invention relates to a method for sorting and recovering garbage, which is characterized in that water is taken as power for flushing garbage in a channel, a set of shredders can be arranged in the channel for tearing the packed garbage, then the garbage is separated by employing a floating precipitation method, water is used for separating substances with density large than water or less than water; for the substance with density large than water, water is taken as a fluid, a multi-stage settling process and a suspension separation process are employed, so that metal, glass, stone and plastic in a settling basin are separated with a suspension separation pool, other substance is sent to a methane tank for fermentation; for the substance with density less than water, after drying and processing steps, foam, film, paper and fiber are separated by using a winnowing method, other substance is sent to a fermentation chamber for fermentation, and the plastic can be filtered and then is sent to a sedimentation basin.
Description
Technical field
The present invention relates to the separating and recovering method of a kind of garbage separating and recovering method, particularly wet type, sedimentation, selection by winnowing combination.
Background technology
Current refuse classification method generally after fragmentation, screening, sorting, magnetic separation, then carries out fermentation process.Due to the particularity of rubbish composition, this processing method is suitable for ore dressing, and for rubbish, just seem inefficiency.
Summary of the invention
Object of the present invention is exactly the waste disposal method that a kind of efficiency of separation will be provided high.
The scheme realizing the object of the invention is:
Be that rubbish is poured channel by power with water, in channel, be provided with one group of shredder bagged garbage is torn, then adopt the floating precipitation method to be separated, with water, rubbish Midst density is greater than water and the separating substances being less than water.Density is greater than to the material of water, using water as fluid, adopt Multistage settling method and suspension partition method, metal, glass, stone, plastics are separated with suspension separate tank at settling tank, and all the other materials are delivered in methane-generating pit and are fermented.Density is less than to the material of water, after dehydration, drying and processing, adopt pneumatic concentration by foam, film, paper, fiber separation, all the other materials are sent into sweathouse and are fermented, and by filtering, plastics are leached rear feeding sedimentation basin.
The invention has the advantages that:
1, method is simple;
2, treating capacity is large, and separative efficiency is high;
3, cost is low, high financial profit.
Detailed description of the invention
Be that rubbish is poured channel by power with water, be provided with one group of shredder and torn by bagged garbage, then send into floating precipitate and separate pond in channel, the material that density is greater than water enters first grade subsides pond by bottom, floating precipitate and separate pond.The flow velocity of adjustment settling tank water, make the larger sinking speed of density faster metal, glass, stone be separated, enter suspension separate tank, all the other materials enter secondary settling tank.Adjustment suspension separate tank water flow velocity upwards, the material making density different is progressively suspended in water separated, and a small amount of foreign material such as pericarp, dish bits are then sent in sedimentation basin.The pericarp be separated in secondary settling tank, dish bits send into sedimentation basin, and all the other materials then send into sedimentation basin again after plastics leach by silk screen, and the sediment in sedimentation basin sends into methane-generating pit process.The material that density is less than water enters floating pool by top, floating precipitate and separate pond, one group of netted scraper plate by chain drive is provided with in floating pool, ceaselessly floating thing is scraped the water surface and send into dehydrator dehydration, then send into hothouse and carry out drying process, blower fan is adopted to carry out selection by winnowing to dried material, plastic sheeting and foamed material are separated, and then carry out dry process further, use the same method and waste paper separated, all the other materials feeding sweathouse carries out fermentation process and then uses filtration method, the difficult materials that rot such as block plastics are separated, all the other materials are sent in sedimentation basin.
Claims (1)
1. a garbage separating and recovering method, it is characterized in that: be that rubbish is poured channel by power with water, in channel, be provided with one group of shredder bagged garbage is torn, then adopt the floating precipitation method to be separated, with water, rubbish Midst density is greater than water and the separating substances being less than water; Density is greater than to the material of water, using water as fluid, adopt Multistage settling method and suspension partition method, metal, glass, stone, plastics are separated with suspension separate tank at settling tank, and all the other materials are delivered in methane-generating pit and are fermented; Density is less than to the material of water, after dehydration, drying and processing, adopt pneumatic concentration by foam, film, paper, fiber separation, all the other materials are sent into sweathouse and are fermented, and by filtering, plastics are leached rear feeding sedimentation basin.
