Abstract
A method for disposing the life garbage in urban area by use of dry cement production system includes such steps as crushing, classifying to obtain the material A which can not be directly burning and the directly combustible material B, separating out the high-Cl plastics, using said incombustible material A as the raw material of cement, and using said combustible material B as the fuel for producing cement.
Description
Technical field
What the present invention relates to is a kind of new method of handling domestic waste-utilize New Type Dry-process Cement Production system handles domestic waste.The interleaving techniques field that belongs to manufacture of cement and urban garbage disposal technology.
Technical background
At present, the processing method to domestic waste mainly is landfill method, composting process and burning method.Landfill method takes up an area of big, subtracts appearanceizations, the resource degree is low, easily to surrounding environment generation secondary pollution.The composting process small scale, the cycle is long, the quality instability, and also the consumer garbage compost amount is big, and nutrient content is low, and long-term use easily causes secondary pollution problems such as soil compaction and groundwater quality degenerate.Burning method can reach innoxious, the target that subtracts appearanceization, resource of domestic rubbish disposal, but burning process is easy to generate “ Er Evil Young " etc. noxious material; needed to handle before emptying; unclean if flue gas is handled; will cause environmental pollution, burning the solid slag that the back produces also needs further processing, if deal with improperly; still can produce secondary pollution, increases difficulty and the investment further handled.This several traditional trash processing way have just been realized the transfer that house refuse is polluted, really do not reach thorough processing house refuse purpose, realize " innoxious, minimizing, resource " requirement of urban garbage disposal.
Summary of the invention
The objective of the invention is to defective, propose a kind of urban garbage disposal process of brand new ideas at above-mentioned existence.Utilize New Type Dry-process Cement Production system handles domestic waste, can utilize firing system to clear up the noxious material that produces in the waste incineration process on the one hand, the lime-ash that is left after the waste incineration can be used as the raw material of cement on the other hand, noxious material in the rubbish resolves into corresponding inorganic matter and heavy metals immobilization in clinker, really accomplish " three change " target of garbage disposal, make harm drop to minimum.
Technical solution of the present invention: the method step that it is characterized in that it was divided into for four steps, one: the domestic waste of collecting is carried out sorting, break process; Two: the total content of chlorine is too high in plastics, when surpassing control criterion and requiring, combustibles such as the plastics that sub-elect, waste paper, plant leaf is carried out the secondary sorting, plastic containing chlorine is sub-elected deal with in addition; Three: the dregs that sub-elects, glass ceramics, kitchen are surplus etc. not directly is used to the part of burning, evenly admix a certain amount of raw material powder or kiln ash, carrying out homogenizing in the excess fermentation of containment kitchen handles, participate in the batching of cement raw material then, deliver in the raw mill, drying, grinding become cement raw meal, enter the homogenizing storehouse homogenizing and store, and then feed firing system together.Four: combustibles such as plastics after the paper that sub-elects, fabric, plant leaf and secondary sorting part is sent into firing system as the manufacture of cement alternative fuel after in small, broken bits.
Advantage of the present invention: utilize cement production system to handle domestic waste and can help the cement plant to solve problems such as energy-conservation and consumption reduction, reduced, reduced destruction to environment and resource to the traditional non-renewable fuel and the exploitation of natural resources.On the other hand, this trash processing way not only can reduce the energy consumption of manufacture of cement, reduce production costs, improve the manufacture of cement benefit, but also reduce the cost of garbage disposal greatly, do not need to increase device for purifying and treating tail gas and waste residue treating apparatus in the similar domestic garbage burning electricity generation treatment process, processing procedure does not rely on the height of refuse thermal value.Utilize New Type Dry-process Cement Production system handles rubbish, because the cement production process main body exists, therefore only need investment construction one cover dumping preliminary treatment and delivery measurement system, add the part of firing system and adjust and transform, its expense is far smaller than the investment of newly-built incineration plant.On operating cost, although the depreciation of equipment, electric power and factors such as raw-material consumption and labour cost make the operating cost of garbage disposal increase, the saving of crude fuel but then, operating cost is decreased, and the economic benefit of bringing will improve constantly along with the increase that substitutes the crude fuel consumption.With refuse classification is plastics, not directly comburant, combustible three major types, and the method for being handled respectively then is a processing method more completely.Simultaneously, cement production process temperature height, the characteristics that alkalescence is strong, residence time of material is long have reduced the pollution of rubbish to environment, the secondary pollution of having avoided processing modes such as landfill and burning that environment is caused.Therefore utilizing New Type Dry-process Cement Production system handles domestic waste is the processing mode of a kind of " doulbe-sides' victory "; help realizing utilizing again and economic sustainable development of resource, also help thoroughly solving numerous social pressures that domestic waste brings to environmental protection.
Embodiment
Get three groups of domestic waste A, B, C, its weight is respectively 1 ton, 0.7 ton, 0.5 ton, carries out following processing respectively, one: it is carried out sorting, break process; Two: the total content of chlorine is too high in plastics, when surpassing control criterion and requiring, combustibles such as the plastics that sub-elect, waste paper, plant leaf is carried out the secondary sorting, plastic containing chlorine is sub-elected deal with in addition; Three: to the dregs that sub-elects, glass ceramics, the kitchen part of burning of not directly being used to such as surplus, evenly admix 0.1 ton raw material powder or kiln ash, carrying out homogenizing in the excess fermentation of containment kitchen handles, participate in the batching of cement raw material then, deliver in the raw mill, drying, grinding become cement raw meal, enter the homogenizing storehouse homogenizing and store, and then feed firing system together; Four: combustibles such as plastics after the paper that sub-elects, fabric, plant leaf and secondary sorting part is sent into firing system as the manufacture of cement alternative fuel after in small, broken bits.
