Description
The invention belongs to refuse classification processing method and device thereof.
Rubbish is the defective work that must produce among the human lives, along with the continuous expansion of city scale, the high concentration of population, the continuous development of activity in production, also in continuous increase, the someone did rough Statistics to the quantity of rubbish, nearly 1,000,000 tons of the annual rubbish that produces in the whole world.The domestic waste problem has become one of the most serious public hazards in the world today.China overwhelming majority cities raw mode that adopts air storage, fill out ditch naturally and fill out the hole municipal refuse of dissolving for a long time, this processing mode all can cause real influence and potential harm to soil, underground water, atmosphere etc.Reach more than 500,000,000 square metre because rubbish is stored up the land area of occupying at present, taken valuable land resource.The rubbish in the most of city of China remains mixed collection, and the intractability of rubbish is big.
The main method of existing treatment of urban garbage:
1, burning method
The method that the simplest and the most most widely used elimination sanitary waste pollutes is waste incineration.The purpose of burning is to remove as much as possible house refuse and pollutes, and the heat that utilizes burning to produce becomes steam or hot water is used for generating electricity.Make the utilization rate of rubbish low but burn, also can bring secondary pollution simultaneously, as the SO in the exhaust emissions
2, NOX and the huge noise in when burning etc.A kind of more advanced method of burning away the refuse-low temperature distillation firing method has been invented by Siemens Company now, this technology is to allow rubbish be introduced into one 450 ℃ destructive distillation chamber, make organic waste be converted into low temperature distillation coal gas and the flue dust that has a large amount of carbon particles, isolate simultaneously through the glass, stone of sterilization, coloured ferrous metal, reclaim.Second step was to burn under 1300 ℃ temperature after low temperature distillation coal gas and the flue dust that has carbon particle are imported the combustion chamber entrained air.The heat of burning is in order to produce high steam, and for generating or distant heating, solids becomes lava shape material to crystallize into slag from the furnace bottom outflow, makes slag brick with it and can do building materials.This method has further improved efficient, has improved the utilization of rubbish, has reduced pollution.Its shortcoming is that construction investment and operating cost are higher.

3, compost treatment
This method is that organic matter in the rubbish and a certain proportion of inorganic matter are mixed together, and the control certain condition is allowed to condition under the action of microorganisms, and Degradation and Transformation is stable Humus, becomes the improvement fertilizer that can impose on the farmland.Its advantage is that part realizes resource, helps big ecological benign cycle.Shortcoming is a long processing period, easily causes secondary pollution.
4, sorting process method
Utilize the proportion size of various compositions in the rubbish, the difference of physical propertys such as magnetic adopts respectively and manually roughly selects, and the method for magnetic separation and pneumatic separation is separated each thing, unified then the recovery.This method is owing to having accomplished to make the best use of everything and pollution is dropped to bottom line to greatest extent, so be one of advanced at present waste disposal method.Because one-time investment is too big, except that minority developed countries such as the U.S. used, majority state was not popularized as yet.But it has represented the developing direction of garbage disposal from now on.One of effective way that addresses the above problem is exactly with the resource recycling of rubbish as a kind of preciousness.The regeneration of rubbish mainly comprises following several aspect: directly recycle, as reusing of glass containers such as beer bottle; Recycling, as utilize the regeneration of waste paper, waste plastics etc.; Comprehensive utilization, as utilize the organic matter in the rubbish to carry out garbage compost, utilize the inflammable substance burning in the rubbish to produce heat energy, realize cogeneration.The regeneration of rubbish is the optimal path of waste reduction and garbage as resource.
The purpose of this invention is to provide a kind of method of separating mixed garbage.
Another object of the present invention provides a kind of device that can realize this refuse classification.
