Abstract
The invention discloses a harmless purification and accretion treatment process of garbage, aiming to overcoming the defects of large occupying area, long transportation route, odor of sewage, dioxin, and the like, serious pollution of smoke dust generated by burning on the environment, high treatment cost, no appreciation utilization of beneficial substances, and the like of the traditional garbage treatment. The harmless purification and accretion treatment process of the garbage comprises the following steps of: carrying out thermal-decomposition purification treatment on the garbage in the environment at 1000-1500 DEG C to generate nutritive ash fertilizers and mixed smoke gases containing a fuel gas, tar, dust, water vapors, and the like; collecting the nutritive ash fertilizers as fertilizers, collecting the mixed smoke gases to be cooled, separating the dust, oil, the water vapors, and the like, and separately collecting the tar and the fuel gas; and carrying out purification treatment on the fuel gas to obtain a pure fuel gas. The harmless purification and accretion treatment process is mainly used for the harmless accretion treatment of urban domestic garbage, can ensure that a station is nearby build on a resident living quarter and continuously purify the garbage into the fuel gas, the tar, the nutritive dust without generating the smoke dust or the dioxin and is thorough in deodorization, sterilization and purification and outstanding in accretion because the pure profit of 410 yuan can be obtained through one ton of the urban domestic garbage.
Description
Technical field
What wood was sent out relates to a kind of garbage treating process, is specially a kind of garbage harmless purifying increment treatment process.
Background technology
The deficiency that conventional garbage landfill, heap fermentation, burning disposal etc. exist is, landed property is many, transit route is long, the flue dust that the stinks such as sewage, bioxin and burning produce is big for environment pollution, processing cost is high, cost is large, and the benefit materials especially in rubbish does not obtain fully effectively rising in value utilization.
Summary of the invention
Object of the present invention is exactly for above-mentioned deficiency, a kind of garbage harmless purifying increment treatment process is provided, garbage purification can be continuously combustion gas, tar, nutrition ash fertilizer by it, smoke dust, to produce Wu bioxin, thorough Pesticidal and sterilizing, remove stink completely, not only purification thoroughly, and increment utilizes.
For achieving the above object, technical scheme of the present invention is, this garbage harmless purifying increment treatment process comprises following processing step:
A. pyrolysis purification: by rubbish pyrolysis purified treatment in 1000-1500 DEG C of environment, generates and obtains nutrition ash fertilizer and the mixed flue gas containing combustion gas, tar, dust, aqueous vapor etc.;
B. refrigerated separation: collect nutrition ash fertilizer as fertilizer, collects mixed flue gas cooling, dust-separating, oil, aqueous vapor etc., separated and collected tar and combustion gas;
C. combustion gas purifying: purification process is carried out in described combustion gas, obtains pure combustion gas.
The refrigerated separation of described step b at least 2 times.
The combustion gas purifying of described step c is spray in water combustion gas being imported water cavity, makes the top of water form mist, and combustion gas is overflowed collection from mist.
Rubbish is placed in 1000-1500 DEG C of environment by the present invention, innoxious complete pyrolysis purified treatment can be carried out continuously, generate the nutrition ash fertilizer and the mixed flue gas that obtain separable utilization, mixed flue gas is through gas collection, cooling, separation, purification process, except dust removal ash etc., be separated tar and clean fuel gas that obtaining to rise in value utilizes.
Result on trial shows, the average one ton of domestic waste of the present invention can produce 0.006 ton, tar, be worth 20 yuan, the combustion gas produced is worth 400 yuan, nutrition ash fertilizer 0.1 ton, is worth 20 yuan, adds up to one ton of domestic waste can rise in value 440 yuan, the removing electricity charge and labour expenses 30 yuan, one ton of domestic waste can have a net gain 410 yuan.
It is estimated, the domestic waste that China produces every year about 300,000,000 tons, the combustion gas adopting the present invention to extract is equivalent to about 1.5 hundred million tons of standard coals, 1,800,000 tons, tar can be produced, nutrition ash fertilizer 0.3 hundred million tons can be produced, income 41,000,000,000 yuan can be created every year, sewage can be reduced, dirty gas discharges 5,000,000 tons, society, environmental protection, economic benefit highly significant.
The present invention can by garbage purification be continuously can rise in value utilize combustion gas, tar, nutrition ash fertilizer, whole process closed operation, not outer smoke evacuation, dirt are Wu peculiar smell fume emissions such as bioxin, do not produce secondary pollution, thorough Pesticidal and sterilizing, removes stink completely, not only purification thoroughly, and increment utilizes.
Scale of the present invention is changeable, manufactures cost of building a station low by 50%, reduces occupation of land 90%, society, environmental protection, economic benefit highly significant.
Detailed description of the invention
Garbage harmless purifying increment treatment process of the present invention comprises following processing step:
A. pyrolysis purification: by rubbish pyrolysis purified treatment in 1000-1500 DEG C of environment, generates and obtains nutrition ash fertilizer and the mixed flue gas containing combustion gas, tar, dust, aqueous vapor etc.;
B. refrigerated separation: collect nutrition ash fertilizer as fertilizer, collect mixed flue gas and carry out 2 water coolings, produce hot water, dust-separating, oil, aqueous vapor etc., separated and collected obtains tar and combustion gas;
C. combustion gas purifying: described combustion gas imported in the water of water cavity and spray, makes the top of water form mist, and combustion gas overflow collection, utilization from mist.
Rubbish can be poured in the pyrolysis chamber without discharged gas fume mouth by the present invention, ignition substance in pyrolysis chamber is ignited after rubbish first, temperature will reach 1000-1500 DEG C, then rubbish can be purified by continuous pyrolysis at this temperature, the chamber wall in pyrolysis chamber had aquaporin and exhaust gases passes, after the complete pyrolysis purified treatment of garbage harmless, be separated into available nutrition ash fertilizer and contain combustion gas, tar, aqueous vapor, the mixed flue gas of dust, collect nutrition ash fertilizer as fertilizer, this mixed flue gas passes through inner passage, through the air collecting chamber be arranged at outside pyrolysis chamber, cooling chamber, the gas collection of disengagement chamber, cooling, separating treatment, except dust, aqueous vapor, separation obtains tar and combustion gas, this combustion gas is transported to purifying mechanism by conveying mechanism and processes further, obtain clean fuel gas, can be used as fuel.
Claims (1)
1. a garbage harmless purifying increment treatment process, is characterized in that, it comprises following processing step:
