Abstract
The utility model discloses a novel marsh gas and air mixer, which mainly comprises a concentric gas inlet pipeline, a filter, a gas mixing chamber and a rectification connecting pipe; the inner end of the concentric gas inlet pipeline is connected with one end of the gas mixing chamber, and the other end of the gas mixing chamber is connected with the rectification connecting pipe; the concentric gas inlet pipeline comprises an air inlet pipeline and a marsh gas inlet pipeline, the marsh gas inlet pipeline is sleeved at the center of the air inlet pipeline, and the filter is installed in an annular passage between the marsh gas inlet pipeline and the air inlet pipeline; and a turbolator is installed in the gas mixing chamber along the axial line thereof. Because of the turbolator designed in the gas mixing chamber of the utility model, the mixed gas of combustible gas and air obtain higher turbulence degree in the gas mixing chamber, enhance the mixing effect and enter an engine combustion chamber after the realization of uniform mixing and the rectification of the rectification connecting pipe. Therefore, the utility model has the characteristics of light structure, large turbulence degree of the mixed gas, uniform mixing and the like.
Description
Technical field
The utility model relates to a kind of new energy use technology field, particularly relates to a kind of marsh gas and air mixer.
Background technique
Biogas is a kind of inflammable gas with higher calorific value, is a kind of inexhaustible, nexhaustible renewable energy sources resource.Marsh gas power generation is a kind of effective means that the biogas high-efficiency cleaning utilizes, it not only can provide the electric energy of cleaning, and can also solve the greenhouse gas emission problem of bringing because of biomass ferment, help turning waste into wealth, realize comprehensive utilization of resources, reduce the discharging of greenhouse gases, become an important technology of waste minimizing, innocuity treatment, for new way has been opened up in the biomass energy comprehensive utilization of the vast rural area of China.
The biogas resource of China is very abundant.In recent years, along with China advances new countryside construction, the methane-generating pit construction is subsidized in state revenue and expenditure energetically, has further transferred the enthusiasm of peasant's construction methane generating pit especially.According to estimates, by 2010, national rural development biomass pool will reach 4,000 ten thousand mouthfuls, produce about 150 billion cubic meters of biogas per year, and what wherein be suitable for developing marsh gas power generation accounts for 11.5% of sum.
At present, the biogas generator ubiquity of selling on the market has problems such as generating efficiency is not high, the comprehensive utilization of energy rate is lower.The reason here is much very complicated, a major reason is wherein arranged, be exactly that biogas is even inadequately with Air mixing before entering engine chamber, cause its not fully burning in the firing chamber (sometimes even can because of mixing the inhomogeneous motor auto extinguishing phenomenon that causes), effective utilization rate of energy is not high, and causes motor undercapacity and efficient on the low side.In addition, can cause the harmful gas composition in the engine exhaust emission to increase again, cause environmental pollution because the biogas burning is insufficient.Therefore, design and develop a novel biogas/air mixer, biogas and air Mixture can evenly be mixed before entering engine chamber, and can improve the turbulivity of mixed gas, with the burning-out rate of raising biogas and the combustion efficiency of motor, will be subjected to the warm welcome in market.
The model utility content
The purpose of this utility model is to provide the marsh gas and the air mixer of the combustion efficiency of a kind of burning-out rate that improves biogas and motor.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of marsh gas and air mixer, and it mainly is made up of concentric circle admission line, filter cleaner, gas mixer chamber, rectification connecting tube; The inner of described concentric circle admission line connects an end of gas mixer chamber, and the other end of gas mixer chamber connects the rectification connecting tube; Described concentric circle admission line is made of air intake pipe and biogas admission line, the biogas admission line is nested with the central authorities at air intake pipe, between biogas admission line and air intake pipe, form the annular pass of air ventilation, the filter cleaner that is used for filtered air is installed in this annular pass; In gas mixer chamber, turbolator is installed along its axis.
Described turbolator is made of spiral helicine a plurality of blades.
Described turbolator also can be made of a plurality of blades that equidistantly are installed in the rotating shaft.
After adopting such scheme, because the turbolator (cyclone device) of design in the gas mixer chamber of the present utility model, make combustible gas (biogas) and Air mixing gas in gas mixer chamber, obtain higher flow-disturbing degree, strengthen mixed effect, realize evenly mixing and by entering engine chamber after the rectification of rectification connecting tube.Air-strainer is installed on the air inlet place of mixer, is used for dust and other foreign material of filtered air, guarantees that engine chamber sucks the air of cleaning.By the said structure innovative design, make that to the utlity model has structure light and handy, characteristics such as the mixed gas turbulivity is big, mix.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along the A-A line;
Fig. 3 is a left side view of the present utility model;
Fig. 4 is a right side view of the present utility model.
Embodiment
As Fig. 1-shown in Figure 4, the utility model is a kind of marsh gas and air mixer, and it mainly is made up of concentric circle admission line 1, filter cleaner 2, gas mixer chamber 3, rectification connecting tube 4.
The inner of described concentric circle admission line 1 connects an end (being combi inlet port) of gas mixer chamber 3, and the other end of gas mixer chamber 3 is a mixed gas outlet, connects rectification connecting tube 4, and this rectification connecting tube 4 is a flaring type conical pipe.
Described concentric circle admission line 1 is made of air intake pipe 11 and 12 two concentric circle admission lines of biogas admission line.Biogas admission line 12 is nested with the central authorities at air intake pipe 11, forms the annular pass 13 of air ventilation between biogas admission line 12 and air intake pipe 11, and the filter cleaner 2 that is used for filtered air is installed in this annular pass 13.
Described gas mixer chamber 3 is the agent structure of mixer, along its axis turbolator 31 is installed in gas mixer chamber 3.In the present embodiment, described turbolator 31 is made of spiral helicine a plurality of blades.In addition, turbolator also can be made of a plurality of blades that equidistantly are installed in the rotating shaft.
The air Cleaner is installed on the air inlet place on two concentric circle admission lines of gas mixer chamber front;
Working principle of the present utility model:
The utility model guarantees motor inhaled air cleaning by dust and other foreign material in filter cleaner 2 filtered airs that are installed on the air inlet place; The gas that installs turbolator 31 by design additional mixes, make biogas and air in gas mixer chamber 3, obtain higher Turbulent Kinetic, realize evenly mixing, and carry out rectification, back importing engine combustion Indoor Combustion, to improve the combustion efficiency of motor by gas after 4 pairs of mixing of rectification connecting tube.
Emphasis of the present utility model just is: install turbolator additional in gas mixer chamber 3.
The above, it only is the utility model preferred embodiment, the structural type of turbolator can have various, so the scope that can not only implement with this structure qualification the utility model, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
