Description
Technical field
The present invention relates to a kind of gas pressure regulation voltage stabilizing mixing arrangement, particularly relate to a kind of bellows-type second voltage regulation pressure stabilized fixer of marsh gas power generation.
Background technique
As everyone knows, gas driven generator group power is on the market general all in 15 kilowatts to hundreds of kilowatt range at present, and does not also have for the small power generation unit (less than 5 kilowatts) of methane-generating pit, which limits the comprehensive utilization of the production and use of marsh gas.Through market survey, the current production and use of marsh gas utilizes very single, and substantially cook, exhaustless biogas has been wasted.
Summary of the invention
The object of the invention is to provide one can effectively utilize the production and use of marsh gas to generate electricity to overcome the deficiencies in the prior art, but also be applicable to the bellows-type second voltage regulation pressure stabilized fixer of civil natural gas, liquefied gas tank generating.Its concrete technological scheme is: bellows-type second voltage regulation pressure stabilized fixer comprises second voltage regulation voltage stabilizer, gas tank, mixer, second voltage regulation voltage stabilizer main body side is connected with an air inlet nozzle, opposite side is connected with an outlet nozzle, a pressure regulation bellows is connected with under second voltage regulation voltage stabilizer main body, pressure regulation bellows inner sleeve is equipped with lower valve core, lower diaphragm, pressure adjusting spring, pressure regulation bellows top has a through hole to communicate with the inlet hole in second voltage regulation voltage stabilizer main body, inlet hole in main body is communicated with upper valve core place cavity by an inclined hole, second voltage regulation voltage stabilizer main body is connected with a voltage stabilizing bellows, upper valve core is set with in voltage stabilizing bellows, upper diaphragm, pressure-stabilizing spring, voltage stabilizing bellows bottom has a through hole to communicate with the air outlet hole in second voltage regulation voltage stabilizer main body, and communicate with outlet nozzle, outlet nozzle outlet is affixed with gas tank, one plastic flexible pipe one end connects gas tank, the other end is connected with mixer main body by pneumatic tube joint, mixer main body is connected with an air filter, airstrainer is set with in air filter, switch valve, diaphragm, Regulation spring.
In order to adapt to civil natural gas, liquefied gas tank generating, mixer main body is also provided with ambient air passage, by regulating screw tap adjusting air inflow quantity.
When using bellows-type second voltage regulation pressure stabilized fixer of the present invention, combustion gas enters into downforce chamber (9) in through main body (6) lower lumen from the lower valve core often opened (13) from air inlet nozzle (5), and the combustion gas in downforce chamber (9) flows into the top inner chamber of main body (6) enter into inlet hole (7) main body (6), inclined hole from hole (8) after.Hole (7) is identical with the circle diameter of hole (8).
One-level pressure regulation illustrates: from the lower valve core often opened (13) the combustion gas quantity flow in downforce chamber (9) to be less than or equal under setting pressure can flow out combustion gas quantity from hole (8) time, pressure adjusting spring (12) can not produce distortion, lower valve core (13) can not close blast tube to be entered, and combustion gas to be entered can continue to flow into.Otherwise, if when the combustion gas quantity flowed in downforce chamber (9) is greater than the combustion gas quantity that can flow out from hole (8) under setting pressure, gaseous-pressure in downforce chamber (9) can constantly increase, gaseous-pressure after increase just impels lower diaphragm (11) to produce distortion, in bellows-type principle, diaphragm, spool, spring are the rigid bodies be linked to be.So lower diaphragm (11) now just can drive pressure adjusting spring (12) to do synchronous compressive strain after being out of shape.Because pressure adjusting spring (12) highly shortens, drive lower valve core (13) is done in the same way, movement on an equal basis, makes it close the flow channel of combustion gas gradually.No matter whether combustion gas flow channel closes, downforce chamber (9) is as long as interior have gas, it all can flow out from hole (8), flow out if only have and do not flow into, gaseous-pressure in downforce chamber (9) can decline rapidly, instantly when the gaseous-pressure in pressure chamber (9) is down to the initial pressure being equal to or less than pressure adjusting spring (12), pressure adjusting spring (12) returns to original height, drives lower valve core (13) to open blast tube simultaneously and recovers in combustion gas inflow downforce chamber (9).
Gas pressure after one-level pressure regulation, no matter flow into gas source pressure much, flowing out the gaseous-pressure in downforce chamber (9), is all a more stable force value.
The combustion gas flow in the inner chamber of main body (6) top enters in upward pressure chamber (3) from the upper valve core often opened (17) again, after combustion gas in upward pressure chamber (3) enters into the air outlet hole (15) on main body (6) top from hole (16), flow out main body (6), flow out from the outlet nozzle (14) be connected with main body (6), flow into gas tank (18) by outlet nozzle (14) and store.Hole (15) is identical with the circle diameter of hole (16).
The mechanism of second voltage regulation, voltage stabilizing is identical with the mechanism of one-level pressure regulation, voltage stabilizing, but due to function, effect different, so some place of its structure is incomplete same.Unlike:
Pressure adjusting spring (12) its initial pressure of one-level pressure regulation is fixing uncomfortable, and the initial pressure of the pressure-stabilizing spring of second voltage regulation (2) is adjustable, it manually can adjust the pressure of multiple different output combustion gas, to meet the needs of engine operation.
Is bleed pressure faced by one-level pressure regulation, pressure change scope greatly, so the initial pressure of pressure adjusting spring (12) is large; Second voltage regulation be for one-level adjustment after output gaseous-pressure, and the pressure that need adjust is very little, much more stable than bleed pressure again, so the initial pressure of pressure-stabilizing spring (2) on secondary is manually all much smaller than the initial pressure of the pressure adjusting spring (12) in one-level after adjustment in any case.
Flow into the combustion gas in gas tank (18), by plastic flexible pipe (19), mixer pneumatic tube joint (20) flows in mixer switch valve (23) tapering lower cavity, after internal combustion engine intake valve is closed, in mixing chamber back-pressure effect under, open in mixing chamber that switch valve (23) enters collection chamber (26) and mix with air.Mixed gas in mixing chamber, is inhaled in cylinder after engine intake valve is opened, and produces play and fires quick-fried soon, promote the piston movement in motor, make engine power in cylinder under high temperature, high pressure.Switch valve (23) in bellows-type mixer and diaphragm (21), Regulation spring (22) is equally also the rigid body connected into.When in the mixing chamber that mixer main body (27) and collection chamber (26) are formed jointly, when the pressure of mixed gas is low (now in-engine intake valve is opened), under the effect of Regulation spring (22) initial pressure, switch valve (23) cuts out, and blocks combustion gas and flows into mixing chamber; When mixture pressure height in the mixing chamber that mixer main body (27) and collection chamber (26) are formed jointly (now in-engine intake valve is closed), Regulation spring (22) compressive strain under the pressure that diaphragm (21) senses promotes, because its length shortens, drive switch valve (23) mobile, open gas inlet passage, combustion gas flows into again in mixing chamber.While switch valve (17) is opened and is started to enter combustion gas, because mixture pressure increases in mixing chamber, it is Regulation spring (22) compression that diaphragm (21) promotes, so diaphragm (21) also can move, after diaphragm (21) is mobile, the air in collection chamber will synchronously enter in mixing chamber and the combustion gas mixing entered.
In addition, for meeting different gaseous fuels or oil fuel, the requirement that this example of its air and fuel mix is different, a bypass air passages directly entered in the upper mixing chamber of mixer main body (27) has been set up at collection chamber (26), and by regulating the air quantity in screw tap (28) adjustment bypass air inflow mixing chamber, the gaseous-pressure that cooperation adjusts second voltage regulation again, voltage stabilizer pressure-stabilizing spring (2) adjustment exports, changes in fuel gas path the combustion gas quantity flowed in mixing chamber whereby; By the above adjustment of the difference to air and fuel, change the mixed proportion of air and combustion gas in mixing chamber, in the hope of reaching the object that a machine pluralities of fuel can be general.This in the market existing gaseous propellant engine cannot realize, be also one of maximum characteristics and advantages of the application's patented technology.
