Description
Technical field
The utility model relates to a kind of equipment for purifying, refers to the pure biological flue gas equipment of a kind of marsh gas water elution especially.
Background technology
The main component of biogas is methane and carbon dioxide, and carbon dioxide content, greatly about 25% ~ 40%, seriously reduces the calorific value of biogas, thus limits the scope of application of biogas as renewable energy source.For improving calorific value and the utility value of biogas, we need to carry out carbonization treatment to biogas.Current marsh gas purifying carbonization treatment method mainly contains pressure swing adsorption process, chemiadsorption, pressure WATER-WASHING METHOD.Pressure swing adsorption process is the separating-purifying being realized gas by pressure change in time, and chemical absorption method is the purification & isolation spatially being realized gas by temperature variation, and pressure WATER-WASHING METHOD is the purification & isolation spatially being realized gas by the change of pressure.The most frequently used is pressure WATER-WASHING METHOD at present, and this method requires that level of automation is low, and facility investment is lower, and major equipment is Marsh gas compression machine and high-pressure hydraulic pump, and relative power consumption is comparatively large, is not too applicable to small-sized methane engineering.Therefore need a kind of energy consumption little, cost equipment low and applied widely solves the problems referred to above.The utility model provides a kind of Low investment, and the marsh gas water of less energy-consumption washes equipment for purifying, solves the problem.
Utility model content
The utility model proposes the pure biological flue gas equipment of a kind of marsh gas water elution, provide a kind of Low investment, the marsh gas water of less energy-consumption is washed equipment for purifying and is solved the problems referred to above.
The utility model is the pure biological flue gas equipment of a kind of marsh gas water elution,
Comprise tourie, described tourie upper end is respectively arranged with vacuum pump and roots blower,
Described vacuum pump is connected with described tourie by communicating pipe a, and described communicating pipe a passes into described tourie inner upper;
Described roots blower is connected with described tourie by communicating pipe b, and described communicating pipe b is provided with reversing valve.
As preferred technical scheme, the other end that described communicating pipe b passes into described tourie is provided with aerator, and described aerator is positioned at the lower inside of described tourie.
As preferred technical scheme, above described tourie, be provided with biogas output channel.
As preferred technical scheme, described roots blower adopts explosion-proof type roots blower.
As preferred technical scheme, described vacuum pump adopts water-ring vacuum pump.
Principle of work of the present utility model is the difference utilizing carbonic acid gas and methane solubleness in water, improves the methane concentration in gas product, then utilizes biogas different with the dividing potential drop of Carbon Dioxide in Air, realize the object of carbon dioxide separation.
During work, biogas is by entering the aerator bottom tourie after roots blower supercharging, form micro-bubble and enter tourie, bubble is in uphill process, carbonic acid gas dissolves gradually, thus improve the quality of biogas, along with time lapse, after the carbonic acid gas dissolved in water reaches finite concentration, carbon dioxide absorption reduced capability, in gas product, gas concentration lwevel rises gradually, at this moment entering of biogas is cut off, change vacuum pump into and suction vacuum operating is carried out to tourie, aerator communicating pipe b is by reversing valve and air communication simultaneously, because tourie internal pressure is low, air enters aerator through communicating pipe b and forms micro-bubble, fully contact with the carbon dioxide enriched aqueous solution, because pressure reduces, carbonic acid gas is parsed in a large number, when in water during gas concentration lwevel access expansion content, again pass into biogas, so repeatedly carry out.Can arrange that multiple devices recycle according to methane quantity and treatment time difference, to complete the continuity of methane purification.Vacuum pump inspiratory capacity is preferably 2 ~ 3 times for roots blower air quantity.Tourie height is preferably 5 ~ 10m, and select roots blower and the vacuum pump pump of convenient pressure according to tourie height, absorption tower water capacity is preferably 2 ~ 3 times of biogas treatment amount, and the bubble diameter of aerator gas explosion is preferably less than or equal to 2.5mm.
Owing to have employed technique scheme, the pure biological flue gas equipment of a kind of marsh gas water elution, utilizes the difference of carbonic acid gas and methane solubleness in water, improves the methane concentration in gas product, then utilize biogas different with the dividing potential drop of Carbon Dioxide in Air, realize the object of carbon dioxide separation.The utility model improves the level of automation of conventional pressure WATER-WASHING METHOD, reduce the energy consumption in carbon rejection process thus reduce cost, and working efficiency is high, good purification.
