Description
Technical field
Patent of the present invention relates to a kind of portable ageing rubbish of disposing, and relates in particular to a kind of portable integrating device and processing method thereof of disposing ageing rubbish.
Background technology
At present, Chinese MSW research growth rate reaches more than 10%, just produces every year nearly 1.5 hundred million tons of municipal refuses.Municipal Solid Waste in China accumulation volume of cargo in storage has reached 7,000,000,000 tons.Domestic maturation and conventional Prediction for Solid Waste Treatment Technology mainly contain 3 kinds of landfills, compost, burning.Wherein Landfill, as tradition and the final processing method of house refuse, still solves the main method of domestic rubbish disposal at present in China most cities.Due to the actual national conditions of China, in strict accordance with the sanitary filling field negligible amounts, particularly urban of standard construction and operation, simple and easy landfill is still taked in early stage and current economically less developed region.Therefore, this part in landfill waste oxious component also can cause severe contamination to atmosphere, soil and water source, not only destroy ecological environment, also serious harm health.Meanwhile, along with the output of house refuse increases at a high speed, the area of required landfill yard is increasing; City scope is constantly to surrounding area expansion, and construction land day is becoming tight, add early stage construction a large amount of refuse landfills oneself through reaching or being about to reach service life, many early stage simple wastes are filled out within Li Chang is put into physical construction planning land used scope.
In order to solve various environment or the social concern such as the pollution of landfill waste team environment and the land used anxiety in city, be therefore thoroughly to process the first-selected approach of landfill waste by the processing method that the rubbish of landfill again excavates and burns.Because house refuse is its easy degraded composition tending towards stability state gradually under microbial action after the landfills of several years is disposed, this class rubbish is called ageing rubbish.Moisture is low except having for ageing rubbish, kitchen excess also has certain calorific value the feature such as stable, the basic odorless of mineralising, is the ideal material of burning disposal.Burning method is first rubbish to be placed in incinerator and to be burnt, and discharges heat energy, and then waste heat recovery can heat supply.After gas cleaning, discharge a small amount of residual residue discharge, landfill or make other purposes.Its advantage is to subtract rapidly appearance ability and high temperature is innoxious thoroughly, and floor space is little, less to surrounding environment influence, and has energy recovery.Therefore, ageing rubbish is carried out to effective processing mode that burning disposal is innoxious, minimizing and resource.But ageing waste incineration project, mainly for the processing of the ageing rubbish of landfill some in specific region, illustrates that this intermediate item has short-term feature, therefore require lower project investment cost.
Chinese patent 201019185064.2; a kind of incinerator is disclosed; comprise: incinerator body of heater; described body of heater comprises the first combustion chamber and the second combustion chamber; the second combustion chamber is positioned at the first side, combustion chamber; the second combustion chamber arranges pipeline communication the first combustion chamber; the first periphery, combustion chamber is provided with flame retardant coating; described the first top, combustion chamber is provided with drying chamber; drying chamber top is provided with charging aperture; drying chamber below is provided with opening, between described opening and the first combustion chamber, is provided with interlayer, in described interlayer, is provided with stop gauge; Between described outer wall of drying room and described flame retardant coating, be provided with smoke-box, described smoke-box is communicated with the second combustion chamber.The use limitation of this incinerator is more, is applicable to burning the rubbish of some lives, and is for new rubbish, and cost of investment is larger simultaneously, and when burning, cyclic utilization rate is lower.
Summary of the invention
