Description
Technical field
The invention belongs to the geseous fuel technical field, specifically relate to a kind of biogas highly industry cutting-welding gas.
Background technology
Along with expanding economy, the raising of people's personal consumption level, the domestic refuse generation in city day by day increases.And at present the city does not also have the engineering measure of rubbish processing to be harmless, and all basically rubbish all is that simple and easy stacking is handled, and does not carry out harmless treatment, and its hygienic requirements does not far reach the hygienic standard of environmental legislation.
These easy place where the garage is piled ups have caused a series of problem of environmental pollution.Show: one, rubbish air storage, distribute a burst of stench, pollutant atmosphere, several square kilometres place can be smelt on every side, has a strong impact on view.Two, rubbish does not have quarantine measures, the percolate polluted underground water of its generation and surface water on every side, the health that greatly threatens the resident.Three, pollute soil on every side, make soil lose due function.
The sustained economic growth in city, the size of population is rising, and goods for consumption is also increasing, if rubbish is not carried out harmless treatment, with causing great disaster.Domestic waste complicated component, enormous amount are one of primary pollution source of environment.The biogas that the garbage loading embeading degraded produces is a kind of greenhouse gases, and the people of annual about 3%-4% is from the methane in the biological degradation biogas for greenhouse gas emission.
The biogas that the garbage loading embeading degraded produces is one of degraded product of sanitary filling field, removes main ingredient CH
4, CO
2Outward, other material that has been detected has more than 140 kinds.Uncontrolled migration of these biological degradation biogas and accumulation can produce secondary pollution, cause the combustion explosion accident; Biological degradation biogas is again one type of greenhouse gases, and it has destruction to atmospheric ozone layer, and data shows, CH
4The Greenhouse effect that produce are than the CO of equivalent volume
2High more than 20 times.
Data shows that rubbish per ton approximately can produce 100 ~ 200m in the landfill yard lifetime
3Biological degradation biogas, its calorific value is generally 7450 ~ 22350KJ/m
3, dehydration back calorific value can improve 10%, removes CO
2, H
2Behind S and other impurity composition, can calorific value be brought up to 22360 ~ 26000KJ/m again
3(calorific value of Sweet natural gas is 37260KJ/m
3), so it is again a kind of potential clean energy.
The biogas that China's municipal wastes landfill degraded at present produces mainly is used for generating electricity, the civilian or direct burning of supply, and its added value is not high, and Operating profit is low.Its garbage degradation that builds up produces biogas project payback period generally at 3-5; As in biogas, adding polyfunctional catalyst; Improve the biogas burning situation, improve combustion thermal efficiency, can substitute acetylene fully and be used for metal flame welding, its economic worth is far longer than generating and supplies civilian; Refuse embedded gas highly industry cutting-welding gas reclaims in the Application Areas at China's refuse embedded gas and is in blank at present, and therefore developing refuse embedded gas highly industry cutting-welding gas has initiative meaning in China.
Domestic refuse produces the methane gas recycling through landfill can apply for the CDM project.Statistics according to UNFCCC; By on May 25th, 2010, the CDM project of registering in Executive Council of United Nations (EB) had 2213, and wherein refuse treatment project has 469; Account for 17% of sum; The landfill gas recycling project of China's registration has 23, and wherein 6 successfully obtain the CER (CER) that EB signs and issues, and amounts to the about 420,000 tons of CO2 equivalents of CER; Refuse landfill generally can be runed 10 ~ 15 years continuously.Operation can be practiced thrift 230,000 tons of standard coal equivalents in 10 years continuously; SO
2Reduce discharging 410 tons; Simultaneously according to the producible CO of conservative installation amount
2CER calculates, and runs and can reduce discharging 4,200,000 tons of CO in 10 years
2,,, can obtain 3,780 ten thousand income by 9 Euros/ton calculating through reducing discharging the international transfer transaction of volume.Economic benefit and the social benefit brought thus are considerable.
1 ton of acetylene gas power consumption of every production, 10800 degree, with 4.5 tons in coke, 16 tons of waters produce 3.5 tons of waste residues and 16 tons of waste water.Every use 1m3 acetylene gas discharges hydrogen sulfide (H simultaneously
2S) 1500mg, phosphuret-(t)ed hydrogen (PH3) 1200mg obnoxious flavour; Adopt biogas highly industry cutting-welding gas and acetylene to compare, biogas highly industry cutting-welding gas per ton can reduce produces the 10800 degree electricity that acetylene consumes, 4.5 tons in coke; 16 tons in water, 3.5 tons of waste residues and 16 tons of waste water.Simultaneously can reduce hydrogen sulfide (H
2S) 1500g, phosphuret-(t)ed hydrogen (PH3) 1200g reduce the CH that produces 20 times of equivalent greenhouse gases because of landfill gas
4The gas pollution on the environment.Therefore biogas highly industry cutting-welding gas has remarkable advantages in economy on environmental protection and the CDM project.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of biogas highly industry cutting-welding gas is provided.
