Description
Technical field
The utility model belongs to Marsh gas treatment equipment technical field, and particularly a kind of stalk produces biogas purification devices.
Background technology
The composition of biogas generally has other gas compositions such as methane, carbon dioxide, oxygen, nitrogen, carbon monoxide, hydrogen, water and hydrogen sulfide.The purifying process of biogas mainly retains its flammable and combustion-supporting components methane, oxygen, carbon monoxide and hydrogen, to the H in biogas
2s, H
2o, CO
2remove with other impurity.
Desulfurization is in order to avoid hydrogen sulfide (H
2s) etching apparatus and pipeline, hydrogen sulfide can make bearing and the corrosion of some matching surfaces in methane fuelled engine and internal combustion engine, makes the deterioration of lubricant of engine, thus accelerates engine scuffing; And the H revealed
2s can cause poisoning, the product S O that its burning is released
2, SO
3be the arch-criminal causing acid rain, compare H
2the harm that S causes also wants large.If dehydration is can dissolved hydrogen sulfide (H because have accumulated water in wireway
2s) corrosion pipeline, in addition when biogas is in later stage pressurized storage, in order to prevent the freezing air accumulator because of condensate water, also must remove water.Remove CO in biogas
2because CO
2reduce the energy density of biogas, calorific value, burning velocity, and increase the firing temperature of biogas, if biogas used needs reach Natural gas standard or be used as motor vehicle fuel, so just must to CO wherein
2remove.
The method removing the hydrogen sulfide in gas is a lot, generally can be divided into dry method and the large class of wet method two.Wet desulphurization can be divided into again oxidizing process, chemical absorption method, Physical Absorption method by the absorption of solution and regeneration properties.Oxidizing process is the catalytic action of borrowing oxygen carrier in solution, and absorbed hydrogen sulfide is converted into sulphur, makes solution obtain regeneration.Mainly contain Ammonia Process, arsenic alkaline process and anthraquinone disulphonate method etc.Chemical absorption method take weakly alkaline solution as absorbent, carries out chemical reaction form compound with hydrogen sulfide, and when rich solution temperature raised pressure reduces, this compound just divides slack, and hydrogen sulfide is released.These class methods have alkyl alcoholamine, alkaline solution method etc.It is absorbent that Physical Absorption method commonly uses organic solvent, and its absorption is entirely physical process, and when rich solution reduces pressure, hydrogen sulfide is just released completely.These class methods have polyglycol dimethyl ether process, cold methyl alcohol method etc.Although wet desulphurization low precision, greatly need reduce gas temperature, it can process the unstripped gas compared with high hydrogen sulfide content, and operating cost is low, is applicable to the features such as large-scale production and industrially widely uses.Dry desulfurization can be divided into chemiadsorption, chemical absorption method and catalytic hydrogenation method three kinds by principle and method.Sulfide in chemiadsorption and desulfurizing agent adsorbed gas thus reach the object of desulfurization, namely active carbon and molecular sieve belong to this type of; Sulfide in chemical absorption method and desulfurizing agent and gas reacts the process removed by sulfide, and its desulfurizing agent has iron oxide, zinc oxide, manganese oxide etc.; Catalytic hydrogenation method and sulfurous gas, when the catalyst such as cobalt molybdenum, nickel molybdenum exist, make organic sulfur conversion be H
2then S is removed.Use iron oxide and activated carbon method the earliest in dry desulfurization, and in the modern industry also conventional dry desulfurization as the means of organic sulfide removal and meticulous desulfurization.
Because sodium carbonate liquor is in alkalescence, sour gas can be absorbed, and due to weakly acidic cushioning effect, when absorbing sour gas, pH value can not change very soon, ensure that the operational stability of system.This solution is to H
2the chemical equation that S absorbs is: Na
2cO
3+ H
2s=NaHCO
3+ NaHS.H is removed in employing alkaline solution method
2in the technique of S, alkaline solution and H
2s reacts, and can reduce the concentration of alkaline solution, thus absorption efficiency is reduced; Alkaline solution method is utilized to remove H in industry
2s, one directly passes in alkaline solution by gas, and another kind is the method adopting spray, and front a kind of method waste alkaline solution, then the ubiquitous problem of a kind of method is spray spray film and H
2s gas can not effectively fully contact, and causes desulfurization degree lower.
Decarbonization method in biogas is liquid absorption method and solid absorption method mainly, and liquid absorption method is divided into two large classes: a class is Physical Absorption method, namely utilizes CO
2it separates by this characteristic that can be dissolved in some liquid from mixture, different solvent absorption CO
2ability different, the purification degrees finally reached is also different, but general all low than the purification degrees of chemical absorbing.Another kind of is chemical absorption method, according to CO
2be the characteristic of sour gas, utilize alkaline absorbent and CO
2carry out chemical reaction to remove.Chemical absorption method just can by the CO in gas under not too high pressure
2be refined to very high degree.But when using chemical absorbing, after chemical absorbent complete reaction is complete, just no longer there is absorption CO
2characteristic, so the absorbability of chemical absorbent is limited.
CO is removed in employing alkaline solution method
2technique in, usually direct gas is passed in alkaline solution, there is CO
2gas can not effectively fully and alkaline solution contact problems, cause desulfurization degree lower; Meanwhile, alkaline solution and CO
2reaction, can reduce the concentration of alkaline solution, thus absorption efficiency is reduced.
