Abstract
A process for reclaiming urban life garbage without environmental pollution features that the organic substance in said garbage is used as fuel for calcining cement clinker or as fertilizer, the ash after calcine and the inorganic substance are used as raw material of cement, and the metal and glass in the garbage are recovered.
Description
The present invention relates to an environmental protection and energy saving project, promptly a kind of domestic waste is innoxious, zero-emission, resource utilization method.
Domestic waste " innoxious, subtract appearanceization, resource " processing and utilizing is a world subject.In China 668 in city is arranged at present, about year house refuse discharge capacity 1.6 hundred million t.Garbage disposal 90% landfill, the landfill that wherein meets sanitary standard is below 10%.Landfill buries secondary resource, accounts for to gulp down the soil, and dust, sewage, pernicious gas contaminated environment are left a legacy of trouble to the descendants.Compost has been a method, but thick compost quality is poor, refining fertile slack market; Burn, " innoxious, subtract appearanceizations, resource " treatment effect is good, once investment greatly, operating cost height, and for the burning facility in early stage, concern is should give in the discharging of the hypertoxic pollutant of dioxin.
The objective of the invention is: domestic waste is innoxious, zero-emission, recycling, industrialized development.Walk " must make great efforts to seek that population, economy, environment and a resource coordinates mutually, can satisfy the demand of contemporary people, the ability of future generations' demand not constituted the road of the sustainable development of harm again.”
For realizing purpose of the present invention, technical scheme is: the 0-100% of organic matter plastic cement, stationery, fabric and other comhustible components of domestic waste utilizes as the fuel of calcination of cement clinker; The surplus composition 0-100% in kitchen utilizes as compost; The combustion ash of calcining cement fuel and inorganic matter dirt composition are as the part material utilization of calcination of cement clinker; Metal in the house refuse, glass are recycled.Domestic waste can be a crude waste, also can be the rubbish after old.
Beneficial effect of the present invention is as follows:
Domestic waste harmless treatment of the present invention is effective, and it is thorough to subtract appearanceization, get utilization, and environmental benefit, remarkable in economical benefits.The present invention has gone out at present the circle of domestic rubbish disposal landfill, compost, burning both at home and abroad, produces close the combination with brand-new attitude greatly with existing society, steps into the industrialized development level road.
1, obvious environment benefit.Dioxin zero discharge, the dirt zero-emission.
Contain about CaO65% in the chemical composition of clinker, the melt zone temperature (1300-1450) of cement burning ℃, and must there be time enough that the C3S of generation is reacted completely, therefore utilize in the domestic waste calcination of cement clinker process, pathogen such as the bacterium in the house refuse, virus are utterly destroyed, the ammonia of stench and organic waste gas are decomposed, and particularly HCl and CaO reaction generates Cal; Flue gas
Discharging can adopt lime to make absorbent, and the gas of discharging is satisfied the criteria, and the dirt after the smoke treatment can be used as
The prepared using of calcining cement.
2, remarkable in economical benefits.Infusion of financial resources is few, and operating cost is low, and recovery of the capital is fast.
The present invention should utilize existing clinker production line in addition technological transformation implement, the infusion of financial resources instrument is used for handling the early stage of technological transformation and rubbish.Infusion of financial resources economizes, and is about 10% of equal scale waste incineration investment in general.Utilize the house refuse calcination of cement clinker can save coal resource etc., utilize garbage entries, national policy is fostered, and enjoys tax reduction and exemption.
3, the cement industry of contemporary Chinese and market are for the invention provides the broad space.Chinese cement output and consumption figure account for more than 30% of the world, account for Asia about 60%, in state-owned cement plant more than 4600 families, be distributed in all over the motherland.
4, the kitchen is surplus makes common compost, content of organic matter height, and price is cheap, obtains the peasant and welcomes.
Implementation of the present invention:
Enforcement of the present invention divides the two-stage, the pretreatment stage of house refuse and recycling stage.
1, the pretreatment stage of house refuse.
The composition of domestic waste has very big discreteness, the composition difference of different cities rubbish, the house refuse component difference in the different locations of areal, also different with ground rubbish because of the changes of seasons composition, although it is ever-changing, we always have rule governed, and pretreatment stage the key link of house refuse is a sorting and grouping, sorting consumer waste of the present invention is sorted out, for example:
(1) plastic cement, stationery, fabric, other combustible of part are made RDF, as the fuel of calcination of cement clinker;
(2) kitchen is surplus: the surplus discreteness in kitchen is very big, the water content height, and calorific value is low, and content of organic matter height sub-elects it from organic matter, make common composting material;
(3) inorganic material: dirt etc., through old homogenizing etc., as the part material of calcination of cement clinker;
(4) metal, glass are recycled;
(5) big part thing is sorted out after the processing again and is utilized.
2, the recycling stage
Utilize the batching of domestic waste calcination of cement clinker, press the desired chemical composition of clinker, determine the composition of used domestic waste earlier, determine the ratio of other raw materials again.The inventor is through repeatedly practice, and house refuse is after the last stage handles, and its composition has relative stability, and the house refuse in general city all can be made the raw material of calcination of cement clinker.Utilize the domestic waste calcination of cement clinker, utilize existing rotary kiln or shaft kiln system to do the necessary technology transformation.Compost, technology maturation is seldom stated.
The present invention is a complicated system engineering, needs to drop into certain manpower, financial resources, material resources.The present invention has realized suitability for industrialized production, and its social benefit, environmental benefit, economic benefit are grand, will make contributions to " people, resource environment, development ".
Claims (2)
1, innoxious, the zero-emission of a kind of domestic waste, resource utilization method, be characterised in that altogether: the 0-100% of the organic plastic of domestic waste, stationery, fabric and other combustible component, fuel as calcination of cement clinker utilizes, the 0-100% of the surplus component in organic matter kitchen utilizes as compost, the combustion ash of the fuel of calcination of cement clinker and inorganic matter dirt are as the part material utilization of calcination of cement clinker, and metal, glass are recycled in the house refuse.
2, innoxious, the zero-emission of a kind of domestic waste according to claim 1, resource utilization method, it is characterized in that: domestic waste can be a crude waste, also can be the rubbish that removes after the corruption.
