Abstract
The invention discloses a system for classifying and recycling various types of solid waste. At present, the waste output in our country is huge, and treatment appliances are not enough, and most of the waste is treated mainly in filling, combusting, stacking and composting manners, the treatment is difficult, and meanwhile, resources are wasted extremely. The system classifies and collects various useful components in solid waste by adopting appropriate and advanced solid waste separation methods and equipment, and mechanical separation is adopted as far as possible; meanwhile, secondary pollution possibly generated during the recycling process is treated pertinently, the secondary pollution hazard is eliminated, and the system has the great popularization and application value.
Description
Technical field
The present invention is a kind of inventing type patent, for the classification of various solid waste (as city solid waste, agricultural solid waste and all types of industries discarded object etc.), reclaims.The various reclaimers of the present invention can be realized the recycling of all kinds of solid wastes.
Background technology
China's noxious waste pollution is controlled and is started late, and treatment facility is built not enough, and along with the quick input of solid waste industry, solid waste treatment facility prospect is very wide.2010, the environmental protection whole industry gross output value reaches 1,200 hundred million yuan, wherein solid waste treatment facility and comprehensive utilization of resources equipment reached the total market size of 12,000,000,000 yuan in 2010, the ratio that accounts for the environmental protection industry (epi) output value by 2008 5% bring up to 11%, the growth rate in solid waste treatment facility market is by the growth rate higher than environmental protection equipment industry, and it is wide that solid waste is processed space, relevant device future market.
During " 12 ", solid waste industry will enter high-speed development period.The annual that the five-year China municipal solid wastes is processed is made an investment in more than 40,000,000,000, and gross investment will reach more than 2,000 hundred million yuan.Wherein treatment of urban garbage investment will reach 86,000,000,000, Treatment of Sludge investment 47,000,000,000, hazardous waste disposal investment 15,000,000,000, Industrial Solid Waste comprehensive utilization investment 20,000,000,000.The Eleventh Five-Year Plan period, China, 65,000,000,000 yuan of solid waste process field investments, accounts for 5.8% of total investment of environment protection.During " 12 ", China's solid waste treatment industry gross output value will reach 8,000 hundred million yuan, compared with the corresponding output value of Eleventh Five-Year Plan, significantly increase.Before the year two thousand twenty, the annual average compound growth rate of China's solid waste aspect investment is expected to remain on more than 20%.Solid waste industry enters the golden period of development, the development of huge investment promoting enterprise, and domestic market will be with digit growth in to the demand of solid waste treatment facility (comprising garbage pulverator).
Useless solid gurry comprises municipal solid wastes, industrial solid castoff and agricultural wastes.The processing of solid waste typically refers to physics, chemistry, biology, materialization and biochemical method and solid waste is converted into the process that is suitable for transportation, stores, utilizes or dispose, and the target that solid waste is processed is innoxious, minimizing, resource.At present conventional processing mode is compacting, brokenly burns after waiting measure preliminary treatment to reduce volume, landfill or compost, or adopts certain sorting by its resource and minimizing.
Summary of the invention
The invention discloses a kind of system that all kinds of solid waste resource recoveries are utilized.
Technological core of the present invention be following some:
1. we,, by a large amount of practices, have found out a set of system of all kinds of discarded objects being carried out to effective classification recovery, and this system can be carried out sorting according to the difference of discarded object density, particle diameter, magnetic and optical property.We can carry out suitable adjustment by recovery process according to the kind of discarded object, the object that reaches economical rationality and reclaim to greatest extent.
2. native system, except conventional fragmentation, screens, and magnetic separation has also adopted more domestic and international advanced sorting technologies outward, as eddy current sorting, light choosing, selection by winnowing etc.For improving the added value of products of separated, also use abrasive dust technology, plastic granulating technology and foam compact technique etc. simultaneously.
3. native system, in solid waste recycling, is avoided problem of secondary pollution as far as possible, and the needed flotation of system and water for cleaning can adopt the water outlet of sewage plant, and system water is processed rear reuse as far as possible, reduces as far as possible amount of makeup water.For the inevitable secondary pollution producing in this process, all use suitable way to solve.The noise producing for this process, we increase separately blimp by the large equipment of noise, and workshop body of wall adds Sound-proof material to be processed; For the issuable waste gas of this process, according to the difference of kind, can adopt spray-absorption, plasma technology or charcoal absorption are processed; For a small amount of sewage, can solve with the usual manner of current main flow.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of flow chart of solid waste recovery sorting.
1. solid waste raw material are through clear water sorting groove 1, when cleaning, carry out carrying out preliminary sorting according to density, according to the difference of density, solid waste raw material is divided into 2 large classes, top is the old metal (being connected with light material) such as plastic sheeting, a small amount of heavy plastics fiber, cloth, a small amount of iron of plank etc., and bottom is various metals, heavy plastics, wiring board and laser disc etc.
2. go up part material through manually tentatively sub-electing bulk rubbish, plastic bottle and pop can etc., leftover materials are through shredder 2, magnetic separator 4, the means such as potcher 8 and centrifugal dehydrator 9 sortings are further separated nonmetal, plastic sheeting and fiber etc., and after plastic sheeting class is dry, granulation is sold.
