Description
Technical field
The utility model belongs to field of renewable energy technology, particularly relates to a kind of desulfurization and decarburization device for adding odor.
Background technology
The energy and environmental problem have become two big outstanding problem of today's society, non-renewable energy resources increasingly reduce and into
In the case of this is increasingly elevated, large and medium-sized biogas engineering is one of important means for solving the energy and environmental problem.Biogas into
Dividing generally has methane (CH4), carbon dioxide (CO2), oxygen (O2), nitrogen (N2), carbon monoxide (CO), hydrogen (H2), water (H2O)
With hydrogen sulfide (H2Other gases compositions such as S).The purifying process of biogas mainly retains its flammable and combustion-supporting components methane (CH4), oxygen
Gas (O2), carbon monoxide (CO) and hydrogen (H2), to the H in biogas2S, H2O, CO2It is removed with other impurity.
Desulfurization is in order to avoid hydrogen sulfide (H2S) etching apparatus and pipeline, hydrogen sulfide is in methane fuelled engine and internal combustion engine
It can corrode bearing and some matching surfaces, make the deterioration of lubricant of engine, so as to accelerate engine scuffing；And leakage
H2S can cause poisoning, its product SO released that burns2、SO3It is the arch-criminal for causing acid rain, compares H2To be endangered caused by S also
Greatly.It is more traditional in biogas desulfurization method to have two class of dry desulfurization and wet desulphurization, the dry desulfurization in industrial applications
Easy to operate, equipment investment is small, its outstanding advantages is degree of purification height, and can remove a variety of organic sulfur compounds, is suitable for scale
Small, biogas desulfurization when sulfur content is relatively low application, otherwise desulfurizing agent replace frequent, it is difficult to solve that sulphur, which cannot effectively recycle problem,
Such as iron oxide process, activated carbon method, sieve method.Wet desulphurization is therein with specific solvent and feed gas, removing
Hydrogen sulfide, the method are generally used for that treatment scale is big, the high thick desulfurization of sulfur content, but it is low there is also Sulfur capacity, purifies low precision
Shortcoming, does not remove organic sulfur generally, applicable to have pressurization WATER-WASHING METHOD, Alkali absorption method, ferrous solution absorption process, tannin extract (tannin)
Method etc..In addition, new biogas desulfurization technique also has the methods of UF membrane desulfurization and biological desulphurization, but operation and maintenance cost
Height, difficulty are big, not yet industrially universal extensive use.And in large-sized biogas industrial applications also without a kind of big ability,
Precision is high, cost is low and can recycle the technique for applying of Sulphur ressource to greatest extent.
Decarbonization method in biogas is mainly liquid absorption method and solid absorption method, and liquid absorption method is divided into two major classes：One
Class is Physical Absorption method, i.e., can be dissolved in this characteristics of some liquid using CO2 separates from mixture it, different
The ability of solvent absorption CO2 is different, and the purification degrees being finally reached are also different, but general all lower than the purification degrees of chemical absorbing.
Another kind of is chemical absorption method, is the characteristic of sour gas according to CO2, using alkaline absorbent and CO2 chemically reacted come
Remove.CO2 in gas can be refined to very high degree by chemical absorption method under less high pressure.But inhaled when with chemistry
In the time receiving, just no longer have the characteristic for absorbing CO2, so the absorbability of chemical absorbent after chemical absorbent has reacted completely
It is limited.
Biogas from anaerobic ferment devices output when, carry substantial amounts of moisture, particularly in medium temperature or hot fermentation, biogas
With higher humidity.When the biogas of higher levels of humidity flows in pipeline, since the change dew point of temperature, pressure reduces, water steams
Air cooling is solidifying to add the resistance that biogas flows in pipeline, and the presence of vapor also reduces the calorific value of biogas, therefore needs
Condensed water in biogas is removed, at present, common biogas dewatering is dehydrated for gravitational method, cold partition method, solvent
Absorption process and solid-state physics water suction method, gravitational method dehydration are removed the part vapor in biogas with biogas gas-water separator,
This biogas gas-water separator mainly installs horizontal strainer and vertical strainer respectively up and down in tower, promotes the water in biogas to steam
Gas and biogas separation, but this device cannot simply and easily collect condensed water, need to additionally increase water collector equipment, add into
This；Cold partition method is to cause temperature change using pressure energy change, the method for making vapor be condensed out from gas phase, such a dress
Putting need to be pressurizeed or decompression processing, complicated and consume energy；Solvent absorption be using dehydrated solvent such as calcium chloride, lithium chloride and
Glycols absorb vapor, this method brings the possibility of other impurities into having while vapor is absorbed to biogas, at the same time
Regularly replace dehydrated solvent；Solid-state physics water suction method absorption produces under the effect of surface of solids power, and adsorbent exists de-
It is the problem of cannot regenerating and need to regularly replacing after water, complicated while of high cost.
