Background technology
Along with the sharply increase of rapid development of economy and population, the problems such as the energy supply and demand contradiction be becoming increasingly acute and the global environmental pollution caused thereof, force countries in the world in succession to carry out exploitation and the research of new forms of energy.Anaerobic fermentation technology can utilize multiple biomass castoff to produce a kind of reproducible biomass energy-biogas, the integrated treatment of the biomass castoffs such as agricultural crop straw, fowl and animal excrement, domestic organic garbage can be widely used in, to the recycling and the environmental pollution improvement that realize biomass castoff, the situation alleviating China's energy demand anxiety is of great immediate significance with improving the ecological environment.
Usually containing H in the biogas that anaerobic reaction produces
2s gas, if biogas directly burns without desulfurization process will form a large amount of SO
2, it is the arch-criminal forming acid rain, by major polluting atmosphere environment.And H
2s gas contains certain corrosivity, uses not through the biogas of desulfurization, by have a strong impact on biogas generator, methane boiler, etc. service life of other equipment.Therefore, biogas must carry out desulfurization process before use.At present, relatively conventional biogas desulfurization method has biological desulfurization and physical chemistry doctor treatment two kinds: physical desulfurization method be mainly by adsorbent by H
2the principle that S Molecular Adsorption is removed on the sorbent, chemical desulfurization method is by chemical desulfurization agent and H such as iron oxide
2s reaction generates simple substance S solid thus by H
2the principle that S removes from biogas; Biological desulphurization rule will generate simple substance S thus the principle it removed from biogas by the biological oxidation process of the microorganisms such as desulfurizing bacteria under the condition of moistening and aerobic.
At present, any sulfur method is taked all to need to increase a set of biogas desulfurization facility outward in addition at anaerobic reactor, need to increase much attached pipeline and pipe fitting, if project scale is larger, the cost of whole desulfurizer is high and floor space is also very large, and place that is nervous at some lands used and small investment will be difficult to implement.
Summary of the invention
The object of the present invention is to provide a kind of biogas desulfurization technique of anaerobic reaction, solve the problem that current biogas desulfurization equipment is all the independent spatial volume that duty is larger outside anaerobic reactor, reach the object reducing overall volume, reduce equipment cost.
Object of the present invention is achieved through the following technical solutions:

2s will with the microbial film generation biological desulphurization process of biologic packing material layer, having H under oxygen existent condition
2s generates elemental sulfur through biological oxidation process, and this process reaction equation is: 2H
2s+O
2=2S+2H
2o
In this reaction, microbe species is based on bacterium, fungi is secondary, rarely saccharomycete, conventional bacterium is the Thiobacillus ferrooxidans of Thiobacillus, thiobacillus denitrificans and thiobacillus thioparus, oxygen in this process is realized to input air in anaerobic reactor body through air duct and the air nozzle be arranged on anaerobic reactor body top cover by the air blast being arranged at anaerobic reactor body exterior, through calculating and practical engineering experience, above-mentioned reaction is carried out well, should keep air content in biogas between 2% ~ 5%, the explosion limit of biogas be 5% ~ 15% biogas in atmosphere, therefore the danger of blast can be got rid of under this condition, in order to the air blast type selecting in Practical Project, input air amount obtains by following formula:
Biogas output (m
3/ d) × 0.0347=input air amount (L/min)
Calculated by above formula, obtain the biogas engineering biological desulphurization air input of different scales as following table:
In practical engineering application, can according to H in fermented feed liquid parameter and biogas
2s content, does certain adjustment to the value of upper table, reaches best to make desulfurized effect.By the device of biological desulphurization is arranged in anaerobic reactor body, sweetening process just can be completed in anaerobic reactor body, relative to the equipment that current biological desulphurization process uses, not only greatly reduce the floor space of equipment, and also ensure that safety, greatly reduce device fabrication cost, be conducive to promoting.
Described air nozzle is evenly distributed on top cover.Further, as a further improvement on the present invention, by being uniformly distributed the mode arranging air nozzle, the oxygen in air can be made to be evenly distributed in gas storage storehouse, avoid partial oxygen too high levels or too low, if oxygen content is too high, then dangerous, there is the possibility of blast, if oxygen content is too low, then be unfavorable for desulfurization, therefore, equally distributed air nozzle can make air dispersed.
Described filler support is made up of angle steel, and is welded on top cover inner surface.Angle steel is further adopted to make filler support, it is not only utilized to be convenient to the characteristic of processing, and its on-deformable feature also makes biologic packing material layer in use avoid tenesmus and cause there is gap between anaerobic reactor body, causes biogas directly to be discharged from biogas outlet without biologic packing material layer.
