Description
Technical field
The invention belongs to biogas production equipment, and in particular to a kind of filtration integrated equipment of biogas wet desulphurization elemental sulfur.
Background technology
Biogas（Biogas）, refer to that organic substance is produced by the decomposition of a variety of anaerobes under anaerobic
Raw mixed gas, main component is methane（CH4）And carbon dioxide（CO2）.In sewage treatment plant, excess sludge is through anaerobism
Biogas is produced after digestion.Biomass waste in sludge through hydrolysis, fermentation, hydrogenesis and acetogenesis three phases finally produce CH4,
CO2 and a small amount of other gases.Biogas, using purified treatment is preceding had to pass through, reaches the quality of biogas as a kind of energy
To standard requirement.Marsh gas purifying mainly includes desulfurization, dehydration and filtered.Desulfurization:When biogas is as using energy source, it is desired to H2S's
Mass concentration meets relevant requirement, otherwise has corrosiveness to pipeline, equipment (such as boiler, methane fuelled engine).
Sulfur method has dry desulfurization, wet desulphurization, Water spray desulfurization etc..Wet desulphurization is usually used in deviating from high concentration sulphur,
The H2S removed in gas is sprayed generally by alkali lye, ideally, H2S liquid meeting regeneration is absorbed, has
Beneficial to cost savings.The species of wet desulphurization is a lot, there is direct oxidation method, chemical absorption method, Physical Absorption method.It is domestic at present normal
Mainly direct oxidation method desulfurization, elemental sulfur is oxidized to by hydrogen sulfide in the liquid phase, and process CIMS is simple, Ke Yizhi
Connect and obtain elemental sulfur.This method mainly for the treatment of concentration of hydrogen sulfide is relatively low and gas that gas concentration lwevel is higher.Wet method
Desulphurization reaction is as follows: Na2CO3 +H2 S NaHS+NaHCO3.Unstripped gas enters desulfurization tower bottom, passes through inner-tower filling material layer
When, sprayed and lower doctor solution (alkali lye) counter current contacting with tower top, alkali liquor absorption hydrogen sulfide generates NaHS, what tower top came out
Hydrogen sulfide mass concentration drops to 20 mg/m3 in purified gas, and processed gas is flowed out by tower top, under entering after gas-liquid separation
One process.Absorb the solution of hydrogen sulfide and be pumped into regeneration tank through circulation and regenerated, solution enters through liquid level regulator after regeneration
Enter recycling at the top of desulfurizing tower.
Wet desulphurization device of the prior art mainly can produce foam sulphur using suspension sulphur, be carried out using water from Flow Technique
Then overflow filters out sulphur to sulphur foam tank；Liquid containing suspension sulphur continues cycling through absorption into mother liquor tank by pipeline and contained
Sulphur gas, is circulated with this.The shortcoming of wet desulphurization device of the prior art is passively to be removed by water from Flow Technique
Sulphur foam, thus can not remove in time, effectively by sulphur foam clean；The other mother liquor containing suspension sulphur has when recycling
Part elemental sulfur can be attached in desulfurization tower packing, it is necessary to periodic cleaning filler；And each water tank has elemental sulfur energetically and sunk to
Bottom, the elemental sulfur cleaning for sinking to water tank bottom is difficult.
The content of the invention
The technical problems to be solved by the invention are that there is provided a kind of biogas production is wet for above-mentioned deficiency of the prior art
The filtration integrated equipment of method desulfurization elemental sulfur, the equipment utilization mechanical scraper device, is actively scraped foam sulphur, timely and effective
Sulphur foam is removed clean in ground；The equipment also has sulphur filter, effectively reduces the suspension sulphur in mother liquor, reduces filler coverlet
Situation about being blocked after the absorption of matter sulphur；The equipment also has foam enhancing device, rebasing elemental sulfur is filtered after stirring, reduction cleaning
Difficulty and cycle.
Invent the technical scheme taken as follows：A kind of filtration integrated equipment of biogas production wet desulphurization elemental sulfur, including sulphur

Mother liquor is taken to enter aeration tower, biogas enters from gas washing tower bottom, contacted by filler, and the mother liquor enters after absorbing sulfurous gas
The rich solution groove, the rich solution groove is connected with the sulfur regeneration groove, and the rich solution groove enters the sulfur regeneration groove by U-shaped mouth,
After auxiliary agent and logical oxygen, sulphur foam and suspension sulphur simple substance are produced, the sulphur froth paddle device in time scrapes away sulphur foam.
Preferably, the equipment also includes sulphur filter, and the two ends of the sulphur filter are connected with the sulfur regeneration groove, institute
The suspension sulphur stated in sulfur regeneration groove reenters mother liquor tank after the sulphur filter, is circulated with this.
Preferably, the sulphur filter is elemental sulfur filter, and the sulphur filter is to go out on bottom is entered, middle be provided with sulphur mistake
Filter the structure of filler.
Preferably, the specific surface area of the sulphur filter packing is 50-240m2/m3。
Preferably, the elemental sulfur gating rate of the elemental sulfur filter is 92%.
Preferably, the equipment also includes foam enhancing device, and the two ends of the foam enhancing device are connected with the sulphur foam tank, leads to
The foam enhancing device is crossed to stir the precipitated sulfur in the sulphur foam tank.
Preferably, after further removing plate compression with pump after the foam enhancing device agitation precipitated sulfur elemental sulfur is obtained to take
Go out.
Preferably, the sulphur froth paddle device is multiple.
Preferably, the sulphur filter is multiple.
Preferably, the foam enhancing device is multiple.
It is that inventor is paying the base of creative work that device is run in the sulphur froth paddle device, sulphur filter and increasing
On plinth, the optimum choice of progress, and found by contrasting, sulphur foam can effectively be removed using said apparatus, filler is prevented
Block or water tank cleaning is difficult.
The beneficial effects of the present invention are：
