Description

Methane-desulfurizing device for blow-off method in anaerobic reactor
Technical field
The utility model relates to the utilization of resources field of big-and-middle-sized biogas engineering and debirs, specifically refers to the methane-desulfurizing device for blow-off method in anaerobic reactor.
Background technology
Along with the sharply increase of rapid development of economy and population, the energy supply and demand contradiction be becoming increasingly acute and the problems such as global environmental pollution that cause 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, can be widely used in the integrated treatment of the biomass castoffs such as agricultural crop straw, fowl and animal excrement, domestic organic garbage, to recycling and the environmental pollution improvement that realizes biomass castoff, the situation of alleviating China's energy demand anxiety is of great immediate significance with improving the ecological environment.
Usually contain H in the biogas that anaerobic reaction produces 2s gas, if biogas without desulfurization process and directly burning will form a large amount of SO 2, it is the arch-criminal who forms acid rain, by major polluting atmosphere environment.And H 2s gas contains certain corrosivity, uses not the biogas through desulfurization, by have a strong impact on biogas generator, methane boiler, etc. service life of other equipment.Therefore, biogas must carry out the desulfurization processing before use.At present, biogas desulfurization method more commonly used has two kinds of biological desulphurization method and physical chemistry doctor treatments: the physical desulfurization method is to be mainly by H by adsorbent 2the principle that the S Molecular Adsorption removes it on adsorbent, the chemical desulfurization method is by chemical desulfurization agent and H such as iron oxide 2thereby the S reaction generates simple substance S solid by H 2the principle that S removes from biogas; Thereby the biological desulphurization rule is that the biological oxidation process by microorganisms such as desulfurizing bacterias will generate the principle that simple substance S removes it from biogas under the condition of moistening and aerobic.
At present, take any sulfur method all need to outside anaerobic reactor, increase in addition a set of biogas desulfurization facility, need to increase a lot of attached pipeline and pipe fittings, if project scale is larger, the cost of whole desulfurizer is high and floor space is also very large, and place nervous at some lands used and small investment will be difficult to implement.
The utility model content
The purpose of this utility model is to be provided for the methane-desulfurizing device of blow-off method in anaerobic reactor, solve current biogas desulfurization equipment and be all independent outside anaerobic reactor and the problem of the larger spatial volume of duty reaches the purpose that reduces whole volume, reduces equipment cost.
The purpose of this utility model is achieved through the following technical solutions:
Methane-desulfurizing device for blow-off method in anaerobic reactor, comprise the anaerobic reactor body, the anaerobic reactor body is cylindric, its top has cone shape top cover, the top of top cover is equipped with the biogas outlet, and the filler support be positioned at below the biogas outlet is installed in described top cover, and the biologic packing material layer is installed on filler support, be provided with a plurality of air nozzles in described top cover inside, air nozzle is connected with the air blast that is positioned at the anaerobic reactor body exterior by air duct.The anaerobic reactor body adopts classical project organization, its integral body is cylindric, top utilizes the top cover of taper to be fixedly connected with, form the closed container of internal cavity structures, at the top of conical top cover, the biogas outlet is installed, normally say that the biogas outlet is positioned at the horizontal level highest point of top cover, filler support is installed on top cover, the biologic packing material layer is set on filler support, the biologic packing material layer is between fermented feed liquid and biogas outlet, form the gas storage storehouse between biologic packing material layer and fermented feed liquid, the biogas that fermented feed liquid produces must could arrive the biogas outlet through the biologic packing material layer, a plurality of air nozzles are installed on top cover, air nozzle is connected with air blast by air duct, in use, air blast passes through air duct, air nozzle injects the oxygen containing air of part in the anaerobic reactor body, the biogas that in feed liquid, anaerobic fermentation produces rises and fully mixes with air in the gas storage storehouse, then through hanging over the biologic packing material layer on filler support, H in biogas 2s will with the microbial film generation biological desulphurization process of biologic packing material layer, H under the condition that has oxygen to exist 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 be take bacterium as main, fungi is inferior, saccharomycete rarely, bacterium commonly used is the Thiobacillus ferrooxidans of Thiobacillus, thiobacillus denitrificans and thiobacillus thioparus, the air blast of oxygen in this process by being arranged at the anaerobic reactor body exterior is through air duct and be arranged on air nozzle on anaerobic reactor body top cover and realize to input air in the anaerobic reactor body, through calculating and practical engineering experience, above-mentioned reaction can be carried out well, should keep air content in biogas between 2% ~ 5%, the explosion limit of biogas is that 5% ~ 15% biogas is in air, therefore can get rid of the danger of blast under this condition, for the air blast type selecting in Practical Project, the input air amount can obtain by following formula:
Biogas output (m 3/ d) * 0.0347=input air amount (L/min)
By above formula, calculate, the biogas engineering biological desulphurization air input that obtains different scales is as following table:
