Description
Technical field
The utility model relates to a kind of gas station, especially relates to a kind of gas station that is applicable to the Rural areas.
Background technology
At present the production and use of marsh gas has family formula (scale is less, uses for a family or two families) and centralized two kinds, and the family formula is built in peasant household's courtyard, the aerogenesis use, centralizedly builds in villages and small towns, utilizes pipe-line transportation to arrive each family.
The patent No.: 200810015421.6, title: central gas supply methane station, a kind of methane station of central gas supply is disclosed, relate to biogas technology, mainly solve the concentrated supply of biogas, its structure is, comprise a solar heated green house and gas-holder, be furnished with stereo storage rack and breather line net in the greenhouse, discharging has the biogas charging basket on the stereo storage rack, the breather line net by main pipe line and progressively the dispersive small transfer line form, the interface with the band check valve of biogas charging basket configuration is arranged on the ventpipe small transfer line, each biogas charging basket is connected with the breather line net by interface; Breather line host pipe connection is to gas-holder, and gas-holder is connected every household by gas transmission pipeline net work again; The heavy caliber container that described biogas charging basket is a with closure is processed with the escape pipe joint on the bucket.The present invention provides concentrated aerogenesis air feed for vast rural area, the methane station of centralized management, but suitability for industrialized production and commercial operation.
The patent No.: 200920096809.3, title: the stalk marsh gas station discloses a kind of stalk marsh gas station of environment-friendly high-efficiency.The utility model stalk marsh gas station comprises the feed reservoir that connects successively, last batch can and fermentor tank; In the described feed reservoir stirrer is set; Described upward batch can connects respectively by gas pipeline carries material storage tank and discharging storage tank, carries the material storage tank vacuum pump is set, and the discharging storage tank is provided with force (forcing) pump; The fermentor tank top is by aerogenesis pipe connection separation purifier; The biogas pipeline that compressor is set connects separation purifier and biogas storage tank respectively.The utility model can be realized the mechanize charging and discharging of stalk, has solved stalk fermentation heat transfer, problem that fermentation efficiency is low.
Above-mentioned patent 1 is centralized methane station, and patent 2 is the stalk marsh gas station, and the two emphasizes the problem in several supply systems of biogas.All do not relate to blending supply with liquefied petroleum gas (LPG).
All there are problems such as aerogenesis insufficient raw material, supply is unstable, the component fluctuation ratio is bigger in family formula and centralized biogas, can not reach the steady quality level and the reliability of city gas pipeline supply, some geographic centralized biogas supply systems, even can only guarantee supply in the early, middle and late meal period.And along with growth in the living standard, the biogas demand that cooking and bathing are used also improves rapidly, only relies on biogas not satisfy, and the peasant household that has built biogas more selects to abandon biogas, turns to the stable bottle gas of supply.
The utility model content
The purpose of this utility model is exactly to provide a kind of air demand stable, reliable for the defective that overcomes above-mentioned prior art existence, and the gas station that is applicable to the Rural areas of environmental protection and energy saving.
The purpose of this utility model can be achieved through the following technical solutions: a kind of gas station that is applicable to the Rural areas, it is characterized in that, this gas station comprises centralized biogas generator, the biogas desulfurization dewatering unit, the liquefied petroleum gas supply device, mixing tank, gas-holder, spark arrester, described centralized biogas generator is connected with the biogas desulfurization dewatering unit, described biogas desulfurization dewatering unit is connected with mixing tank, described liquefied petroleum gas supply device is connected with mixing tank, described mixing tank is connected with gas-holder, and described gas-holder is connected to the user by spark arrester and uses device of air.
Described centralized biogas generator comprises fermentation unit, whipping appts, feeding unit, sludge pump, drawing mechanism, described whipping appts is arranged in the fermentation unit, described feeding unit is connected with fermentation unit by sludge pump, and described drawing mechanism is connected with fermentation unit.
Described biogas desulfurization dewatering unit comprises water-sealed tank, digester, and described water-sealed tank is arranged between fermentation unit and the digester, and described digester is connected with mixing tank.
Described gas-holder is a liquefied petroleum gas steel cylinder.
Described mixing tank is an inspirator mixer.
Compared with prior art, the utlity model has following advantage:
1, patent device is provided with inspirator mixer, because liquefied petroleum gas (LPG) is being become in the gaseous process by liquid state, need to absorb heat, pressure can increase (the highest 1.5MPa), and the pipeline top pressure that is transported to the user place only has 2.5kPa, therefore can be in the process of liquefied petroleum gas (LPG) decompression that pressure is very low biogas injection, realize uniform mixing, mixing process does not need external energy.And the injector reasonable in design blending ratio that can remain unchanged automatically, that is: the flow of liquefied petroleum gas (LPG) increases, when pressure improves, can be increased in proportion by the biogas amount of injection, thereby guarantees the constant rate of gas mixture.
2, the gas station of patent device does not need a large amount of biogas raw materials.The calorific value of liquefied petroleum gas (LPG) is 5～7 times of biogas, and a spot of liquefied petroleum gas (LPG) is alternative a large amount of biogas., breeding and planting industry relatively underdeveloped Rural areas economically developed for some can focus on by mass-producing, effectively utilize crop material, feces of livestock and poultry and domestic refuse, alleviate environmental pollution.
3, the gas station of patent device can with liquefied petroleum gas (LPG) and air blending, utilize original pipe-line transportation in the season that does not have the biogas raw material, by the Adaptive Technology of combustion equipment, and works better such as the gas-cooker at assurance user place, water-heater.Can realize the reliability and stability the same like this, really with the technical commercialization degree that is raised to of biogas utilization with city gas supply.
4, along with Economic development, when the gas distributing system system can insert in the future, available Sweet natural gas replaced liquefied petroleum gas (LPG), continued the blending supply.Only need the burner at end user place is changed transformation.Pipe network and station equipment continue to use.
