Description
Technical field
The invention belongs to Marsh gas treatment equipment technical field, particularly a kind of Methane Resources treatment system with efficiently purifying function.
Background technology
Since entering 20 century 70s, along with the impact of global oil crisis and the raising of environmental consciousness, exploitation and the efficient converting biomass energy are more and more paid attention in countries in the world, have formulated developmental research plan one after another.The energy farm of the U.S., the sunlight program of Japan, the green energy resource engineering of India and the alcohol energy plan of Brazil were all the special project supports for biomass research and development, and China started Eleventh Five-Year Plan national science and technology supporting plan " agricultural-forestry biomass engineering " major project in 2006.Current Biomass Energy Utilization amount accounts for 14% of total worldwide energy, is equivalent to 12.57 hundred million tons of oil.According to United Nations Environment Programme (UNEP), all kinds of cereal of planting in the world can provide stalk 1,700,000,000 tons every year.2008, can collect agricultural straw resource amount China's year was 6.87 hundred million tons, therefore the having a high potential of Crop in China stalk producing natural gas.
But prior art technology in stalk product process of methane is immature, and the problems such as ubiquity gas production rate is low, and biogas purity is not high, hinder the recycling that stalk produces biogas.
The composition of biogas generally has other gas compositions such as methane, carbonic acid gas, 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.
Because sodium carbonate solution is in alkalescence, sour gas can be absorbed, and due to weakly acidic shock absorption, 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 basic solution method
2in the technique of S, basic solution and H
2s reacts, and can reduce the concentration of basic solution, thus assimilated efficiency is reduced; Basic solution method is utilized to remove H in industry
2s, one directly passes in basic solution by gas, and another kind is the method adopting spray, and front a kind of method waste basic 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 absorbing CO
2ability different, the purification degrees finally reached is also different, but general all low than the purification degrees of chemical absorption.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 absorption, after chemical absorber complete reaction is complete, just no longer there is absorption CO
2characteristic, so the receptivity of chemical absorber is limited.
CO is removed in employing basic solution method
2technique in, usually direct gas is passed in basic solution, there is CO
2gas can not effectively fully and basic solution contact problems, cause desulfurization degree lower; Meanwhile, basic solution and CO
2reaction, can reduce the concentration of basic solution, thus assimilated efficiency is reduced.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Methane Resources treatment system with efficiently purifying function is provided.Biogas purification devices in this system effectively can make spray alkalescence spray film and H
2s gas fully contacts, and improves the utilization ratio of desulfuration efficiency and desulfuration solution; Meanwhile, effectively CO can be made
2gas fully contacts with basic solution, utilizes the basic solution that sensor and electrically-controlled valve provide new in real time simultaneously, ensures the concentration of basic solution, to ensure to continue higher decarburization efficiency.This system is convenient for production, strong operability, effectively achieve the recycling of stalk, achieves and turns waste into wealth, green circulation economy.
