Description
Technical field
The utility model relates to a kind of biological desulphurization system, particularly the circulating methane bio-desulfurization system of one.
Technical background
Sludge treatment and industrial organic waste water process many employings anaerobic biological method, produce a large amount of biogas in treating processes, this kind of biogas contains inflammable gas methane, is also harmful to fully containing hydrogen sulfide etc.Hydrogen sulfide is a kind of strong neurotoxic substance, and its toxicity is suitable with cyanic acid gas.During biogas combustion, hydrogen sulfide wherein also can be converted into the very strong sulfurous acid aerosol of corrodibility, contaminate environment border, etching apparatus.Therefore, the harm caused to prevent hydrogen sulfide, must carry out desulfurization before biogas utilization.
At present, the biogas desulfurization technique of domestic extensive employing is dry method, and this method is widely used and have accumulated a lot of experience.But its main drawback has floor space large, and desulphurization cost is high, cannot realize working continuously.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of floor space little, device height is integrated, the simple methane bio-desulfurization system of Operation and Maintenance.
For arriving above-mentioned purpose, the utility model have employed following technical scheme.
Methane bio-desulfurization system, comprise side with entering biogas pipe, upper end with going out biogas pipe, the inner washing tower with biologic packing material, washing tower also supplements pipe with washings, washing tower is also with return line, return line is connected with the spray equipment being positioned at washing tower inner upper end, it is characterized in that: also comprise to be connected with washing tower by washing lotion tube and in establish the bio-reactor of aerating apparatus; Described aerating apparatus is connected with the gas blower be positioned at outside bio-reactor by pipeline; Also comprise the sulphur separator be connected with bio-reactor by upflow tube, sulphur separator is connected with desulphurization pump; Also comprise the mixed solution house steward be connected with bio-reactor by recycle pump, mixed solution house steward is connected with distribution piping, and distribution piping is also connected with described sulphur separator and described return line respectively.
The upper end of bio-reactor is also with Waste gas outlet.
Distribution piping is also connected with liquid discharge pipe.
The utility model has following characteristics.
Sulfide hydrogen biogas enters washing tower from biogas pipe, through go out biogas pipe discharges system after removing hydrogen sulfide in washing tower with spray alkaline reaction.Hydrogen sulfide containing washings is from flowing to bio-reactor, and add thiobacillus in bio-reactor, hydrogen sulfide is converted into elemental sulfur through biological respinse, and alkali obtains bio-regeneration.The washings flowed out from bio-reactor and the mixed solution of elemental sulfur pump into mixed solution house steward through recycle pump, and part flows in described sulphur separator, and part returns washing tower through return line flow.In sulphur separator, the product sulfur precipitation is also separated with washings, and the product sulfur discharges system through desulphurization pump, enters sulphur mud storage tank.Washings gets back to bio-reactor through upflow tube.Self-circulation in washings formation system, alkali is obtained bio-regeneration recycle after divorced.Have treatment effect good, equipment is simple, investment and working cost low, security is good, non-secondary pollution, is easy to the advantages such as management.Also have floor space little, device integration is high, the simple feature of Operation and Maintenance.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model and principle of work schematic diagram.
Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, embodiment of the present utility model comprises side with entering biogas pipe 2, upper end with going out biogas pipe 5, the inner washing tower 1 with biologic packing material 3.Washing tower 1 also supplements pipe 4 with washings, adds alkali lye for adding for the first time and supplement in system.Washing tower 1 is also with return line 6, and return line 6 is connected with the spray equipment being positioned at washing tower 1 inner upper end.Embodiment of the present utility model also comprise to be connected with washing tower 1 by washing lotion tube 17 and in establish the bio-reactor 15 of aerating apparatus 14.Described aerating apparatus 14 is connected with the gas blower 7 be positioned at outside bio-reactor 15 by pipeline.Washing absorption, also with Waste gas outlet 8, for connecting the exhaust gas scrubber of Sewage Plant, is carried out to a small amount of waste gas that bio-reactor 15 produces in the upper end of bio-reactor 15.Embodiment of the present utility model also comprises the sulphur separator 12 be connected with bio-reactor 15 by upflow tube 13, and sulphur separator 12 is connected with desulphurization pump 11.
Embodiment of the present utility model also comprises the mixed solution house steward 18 be connected with bio-reactor 15 by recycle pump 16, and mixed solution house steward 18 is connected with distribution piping 9, and distribution piping 9 is also connected with described sulphur separator 12 and described return line 6 respectively.Distribution piping 9 is also connected with liquid discharge pipe 10.Discharge section waste liquid when the effect of liquid discharge pipe 10 is fluid overload in system.
Sulfide hydrogen biogas enters washing tower 1 from biogas pipe 2, through go out biogas pipe 5 discharges system after removing hydrogen sulfide in washing tower 1 with spray alkaline reaction.The effect of biologic packing material 3 increases gas liquid interfacial area, improves reaction efficiency.
Hydrogen sulfide containing washings is from flowing to bio-reactor 15, and add thiobacillus in bio-reactor 15, hydrogen sulfide is converted into elemental sulfur through biological respinse, and alkali obtains bio-regeneration.Biological respinse is by means of aerating apparatus, and aerating apparatus provides air by gas blower 7.
