The automatic regulating device has the advantages of simple structure and is convenient and practical and easy to operate, and the like.
Description
Technical field
The utility model relates to the marsh gas power generation machine technology, relates in particular to a kind of Biogas Generator Set air fuel ratio automatic control tegulatingdevice.
Background technique
Existing fuel gas generation unit mainly is to utilize rock gas to be fuel power generation function.Although the China's natural gas aboundresources, it is limited and development cost is high as a kind of non-renewable energy resources reserves.People begin attempt to use marsh gas power generation, but marsh gas power generation is different from rock gas, and the effective component of marsh gas power generation is methane, and its content is about 50%-70%, and is and fixing unlike rock gas.So insoluble problem has appearred in the gas mixer of natural gas power unit for biogas the time, conventional gas mixer can't satisfy startup and the normal operation of generator set, namely how rationally to regulate the air inlet amount according to the methane content in the biogas, guarantee the normal operation of Biogas Generator Set to reach suitable air fuel ratio.
Existing generator set for biogas need to be set up mechanical valve in addition, according to the methane content of biogas, the manual tune valve is to realize suitable air fuel ratio, this design is very unfavorable in when operation, not only consumes human resources but also requires very high to operator's proficiency.
The model utility content
There is above technical problem for Biogas Generator Set, the utility model provides a kind of air fuel ratio automatic control tegulatingdevice for the difference of biogas composition, the air inflow that can automatically regulate biogas, air according to the variation of the methane content of biogas is to reach the required condition of the normal start-up and operation of Biogas Generator Set.
In order to realize above goal of the invention, the utility model by the following technical solutions, Biogas Generator Set air fuel ratio automatic control tegulatingdevice, formed by mixing chamber, piston type diaphragm, spring, mixing regulating spool, be provided with biogas suction port, air inlet and mixed gas air outlet on the wherein said mixing chamber, the piston type diaphragm passes through the elastic compression of top spring at the biogas air inlet port of mixing chamber inside; Mix regulating spool and be inverted cone-shaped, be arranged on the piston type diaphragm, the cone tip is goed deep in the biogas suction tude.
Further, described mixing regulating spool can be the little hemisphere of upper end radius large lower end radius.
Its working principle is, when the biogas air inlet, air inlet air pressure pushing piston formula diaphragm and spring move up, mix regulating spool with on move.Intake velocity is fixedly the time, and the air inlet air pressure of the biogas of different methane contents is different, and is different to the upper thrust of piston type diaphragm and spring, and the opening degree of mixing regulating spool changes thereupon.When methane content of bilogas was low, spool reduced unit area air inlet amount, improves the biogas air inflow; When methane content of bilogas was high, spool improved unit area air inlet amount, reduces the biogas air inflow, and the mixed proportion of namely rationally having regulated biogas and air has remained suitable air fuel ratio, had guaranteed that mixed gas enters fully burning in the engine cylinder.
The Biogas Generator Set air fuel ratio automatic control tegulatingdevice that adopts the utility model to provide, realized the automatic adjusting of biogas and air mixed proportion, solved the problem that the conventional gas mixing arrangement can't use on biogas generator, solved methane content of bilogas and changed the normal impact that moves of Biogas Generator Set.The utility model does not need manual operation, does not need to set up in addition machinery valve yet, has the advantages such as simple in structure, convenient and practical, easy to operate.
Description of drawings
Fig. 1 is the utility model Biogas Generator Set air fuel ratio automatic control tegulatingdevice structural representation.
Wherein, reference character: shell-1; Mixing chamber-2; Piston type diaphragm-3; Spring-4; Mix regulating spool-5; Biogas suction port-6; Air inlet-7.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is done further detailed, clear, complete explanation, meet novelty, creativeness and the practicability that Patent Law requires fully with explanation the utility model.What should be noted that embodiment describes is a part of mode of execution of the present utility model, can not be used for limiting protection domain of the present utility model.
Biogas Generator Set air fuel ratio automatic control tegulatingdevice, formed by mixing chamber 2, piston type diaphragm 3, spring 4, mixing regulating spool 5, be provided with biogas suction port 6, air inlet 7 and mixed gas air outlet on the wherein said mixing chamber 2, the piston type diaphragm passes through the elastic compression of top spring at the biogas air inlet port of mixing chamber inside; Mix regulating spool 5 and be inverted cone-shaped, be arranged on the piston type diaphragm 3, the cone tip is goed deep in the biogas suction tude.
Further, described mixing regulating spool can be the little hemisphere of upper end radius large lower end radius.
Its working principle is, when the biogas air inlet, air inlet air pressure pushing piston formula diaphragm and spring move up, mix regulating spool with on move.Intake velocity is fixedly the time, and the air inlet air pressure of the biogas of different methane contents is different, and is different to the upper thrust of piston type diaphragm and spring, and the opening degree of mixing regulating spool changes thereupon.When methane content of bilogas was low, spool reduced unit area air inlet amount, improves the biogas air inflow; When methane content of bilogas was high, spool improved unit area air inlet amount, reduces the biogas air inflow, and the mixed proportion of namely rationally having regulated biogas and air has remained suitable air fuel ratio, had guaranteed that mixed gas enters fully burning in the engine cylinder.
Described piston type diaphragm and mixing regulating spool generally adopt corrosion resistant metal to make, and when calculating the biogas air inflow, should consider the intake velocity of biogas, the deadweight of spool and the elastic force of spring.
