Description
Technical field
The utility model relates to a kind of Sweet natural gas biological desulphurization bacterial classification ability to function proofing unit.
Background technology
Along with society constantly enlarges Natural Gas Demand, the exploratory development dynamics also further strengthens thereupon, increasing in low sulfur-containing gas disperse well to be included into the category of development and use.For this class gas well, seek the desirability that a kind of cost-effective purifying method becomes development.From economic target and treatment effect Comprehensive Assessment, during less than 0.1t/d, dry desulfurization is comparatively suitable at latent sulfur content; Dive sulfur content during greater than 50t/d, and amine method+claus process just can demonstrate fully economic benefit; When latent sulfur content occupy between the two, at present at home and abroad comparatively desirable mode often adopts liquid-phase oxidation reduction and desulfurization technology to process, yet the main drawback of liquid-phase oxidation reduction is that chemical cost is high and it is stifled that sulphur easily occurs, and causes the increase of running cost.By comparison, biological desulfurization process has just remedied above-mentioned deficiency, and the alkali that absorption process consumes acts in the bio-reactor by microorganism catalysis and to be recovered, and has reduced the consumption of chemical; The sulphur that generates has wetting ability, is difficult for causing sulphur stifled, and hydrophilic sulphur also can be done agrochemical and sterilant, has improved added value; Whole scavenging process does not have the generation of chemical degradation liquid, and is very friendly to environment.
Although the generation of biological desulphurization concept is more than two decades only, but because its characteristics adapt to development and the environmental requirement of following desulfurization technology very much, Abroad in Recent Years developed country drops into a large amount of manpowers and fund is accelerated its research and development, so that the development of this technology and the popularization impetus are unusually swift and violent.Developed jointly the Shell-Paques biological desulfurization process as example take Shell and Paques company, at present, Shell company has worldwide had 45 cover biological desulphurization commercialization devices, be distributed in oil refining, the change, the industrial circle such as Sweet natural gas, mining industry, paper-making industry and biogas, 5 cover commercialization application of installations are wherein arranged in the natural gas conditioning field, report from on-the-spot service data, really a kind of efficient, safety, economy, the easy-operating desulfurization technology of biological desulphurization, in in the purifying treatment of low sulfur-containing gas, technology economy advantage is obvious.But at present there is still lower problem of ability to function in Sweet natural gas biological desulphurization bacterial classification.
The utility model content
The purpose of this utility model provides a kind of Sweet natural gas biological desulphurization bacterial classification ability to function proofing unit, detection utilizes the genome rearrangement technology to improve fast Sweet natural gas biological desulphurization bacterial classification ability to function, solves the lower problem of present Sweet natural gas biological desulphurization bacterial classification ability to function.
Sweet natural gas biological desulphurization bacterial classification ability to function proofing unit described in the utility model is comprised of absorption tower, bio-reactor, settling vessel and solution pump; The sulfur-containing gas import is arranged on the bottom, absorption tower, the gas distributor below that arranges in the absorption tower, the top is provided with the cleaner outlet, the outlet that is arranged on the bottom, absorption tower is connected by pipeline with the import that bio-reactor is arranged on the bottom, the outlet that bio-reactor is arranged on top is connected with the entrance that is arranged on top, absorption tower with connection line by solution pump, the outlet that bio-reactor is arranged on the bottom is connected with the import of settling vessel bottom, the outlet that settling vessel is arranged on top is connected with the entrance that bio-reactor is arranged on top, the bio-reactor bottom is provided with alkali lye, air and nutritive medium feeding line, the top is provided with the discharging gas port, settling vessel is that a bottom is the cylindrical shell of cone, the outlet of sulphur slurry is positioned on the cylinder body bottom cone point, the relief liquor outlet is arranged on the junction of cone and cylindrical shell, and settling vessel top cylindrical shell is communicated with bio-reactor top cylindrical shell.
The gas distributor that sulfur-containing gas arranges by the bottom, absorption tower passes through the absorption liquid in the absorption tower from lower to upper, and purified gas is discharged from the top, absorption tower, and the liquid that has absorbed H2S is poor from the absorption tower flow direction bioreactor by two position.In bio-reactor, alkali lye and nutritive medium are added by two pipelines receiving the bio-reactor bottom.Air blasts from the bio-reactor bottom, forms the gas lift reactive system, also provides electron acceptor(EA) and gas lift power for the sulfide in the thiobacillus oxidation liquid phase simultaneously.The sulphur that oxidation generates is because density difference enters settling bowl after coming downwards to reactor bottom, and the settling bowl supernatant liquor rises to absorption tower cat head recycle by peristaltic pump.
Use this Sweet natural gas biological desulphurization bacterial classification ability to function proofing unit, obtained at H
2Under the makings condition of S concentration up to 200g/m3, its purification rate can reach nearly 100% efficient natural desulfurization bacterial classification, has significantly improved Sweet natural gas biological desulfurization process economy and makings adaptability.
