Description
Technical field
The utility model relate to a kind of aerobic/anaerobism integrated methane safe biologic desulfurizer, be applicable to the biogas desulfurization engineering.
Background technology
Biogas and electric power thereof are class clean energies, and its development and utilization itself is exactly a kind of eco-friendly measure, and the image-stone energy is not such for it, need society's a large amount of cost of cost to go to administer it and pollute to avoid environmental damage.Therefore, this technology was subjected to extensively paying attention to and actively promoting in the nearly more than ten years, had formed new industrial colony in part developed country.Under world today's energy starved situation, make full use of the biogas energy, can alleviate the pressure that China's energy scarcity brings.
Biogas is a kind of flammable mixed gas, generally contains methane, carbonic acid gas and a spot of ammonia, hydrogen and carbon monoxide etc., often contains the hydrogen sulfide of different content in the biogas that different raw materials is made.Hydrogen sulfide is a kind of obnoxious flavour of severe toxicity, and it has the intensive corrosive nature to pipeline, instrument and equipment, and leakage with atmosphere pollution, is detrimental to health in air.Therefore,, prolong service life of equipment, must adopt an effective measure and carry out biogas desulfurization in order to protect HUMAN HEALTH.Environmental Protection in China standard strict regulation: when utilizing biogas energy, hydrogen sulfide content must not surpass 20mg/m in the biogas
3Hydrogen sulfide mass concentration in the biogas is generally 1～12g/m
3, be higher than the regulation of Environmental Protection in China standard far away.Therefore, removing of hydrogen sulfide becomes a requisite link in the biogas use.
The method of biogas desulfurization has chemical method, physico-chemical process and biological process etc.Physico-chemical process and chemical method commonly used generally can be divided into direct desulfurization and indirect desulfurization two big classes, and direct desulfurization directly separates hydrogen sulfide in methane gas exactly, and indirect desulfurization is meant the employing concrete grammar, reduce or suppress the generation of hydrogen sulfide in the biogas production.The principle of biogas direct desulfurization method can be divided into damp process and drying process two classes, and damp process mainly contains WATER-WASHING METHOD, ADA method, improvement ADA method, arsenic alkaline process and alkaline saline solution method etc.At present, state's inner desulfurization technology is comparative maturity, and sulfur method and sulfur removal technology are numerous, and the desulfurization technology of widespread usage is based on physico-chemical processes.But in general, utilize the physico-chemical process biogas desulfurization to exist following shortcoming: dry desulfurization efficient is not high, sweetening agent regeneration difficulty, and Sulfur capacity is relatively low, mainly is applicable to meticulous desulfurization; The wet desulphurization treatment capacity is big, desulfuration efficiency height, but operate continuously, but the investment working cost is also high, and the biogas utilization general user is difficult to bear.Along with the strictness day by day of environmental regulation, the technology of exploitation efficient, low input, resource utilization and non-secondary pollution has become the main flow of desulfurization technology development.In order to solve some drawbacks of physico-chemical process desulfurization, seek more efficient desulfurization technology, the biological desulphurization method is arisen at the historic moment.Biological desulphurization is because of having less contamination, less energy-consumption and high-level efficiency, and characteristics such as recyclable elemental sulfur, becomes the focus of research.
Biological desulphurization is to utilize the metabolism of microorganism that the hydrogen sulfide in the biogas is converted into elemental sulfur or vitriol.Its reaction formula is respectively:
2HS
-+O
2→2S+2OH
- (1)
2HS
-+4O
2→2SO
4 2-+2H
+ (2)
At present, biological desulphurization has obtained certain applying, but still exists problems to need to be resolved hurrily.Shown in reaction formula (2), thereby sulfide can be oxidized to the efficient that vitriol influences desulfurization under the situation of oxygen excess.This does not wish to take place in sweetening process.How to control rational aeration rate, make the end product behind the biological desulphurization be controlled to be the key point that sulphur simple substance has just like become the methane bio-desulfurization technology.In addition, the direct potential safety hazard that has blast of mixing of air and biogas, how getting rid of hidden peril of explosion is the difficult point of methane bio-desulfurization technology.Recently, have the investigator to find that a class has the microorganism that simultaneous denitrification removes sulfur functional, following reaction can take place in them under the condition of complete anaerobic:
5HS
-+2NO
3 -+7H
+→5S+N
2+6H
2O。(3)
This reaction has avoided biogas to contact with the direct of air, can get rid of the potential safety hazard of blast.This reaction also has the application prospect of synchronous biogas desulfurization and denitrogenation of waste water, but still find no at present this reaction is applied to the biogas desulfurization engineering.
