Abstract
The invention relates to the field of engines and discloses a silencer capable of improving the efficiency of a fuel gas solenoid rotary engine. The silencer comprises the fuel gas solenoid rotary engine. An engine shell connected between bearings at the two ends of the fuel gas solenoid rotary engine in a bridging mode is in sealed connection with a rotary shaft, and an exhaust port is formed in the engine shell and located at the cup-shaped body end of a combustion chamber, so that exhaust gas discharged from a solenoid rotor flows to the exhaust port to be discharged along a gap formed between a solenoid rotor, the cup-shaped body of the combustion chamber and the engine shell. The integrated silencer is formed by fully utilizing the structural characteristics of the fuel gas solenoid rotary engine, the efficiency of the fuel gas solenoid rotary engine is improved, and cost is reduced due to the fact that independent arrangement of a silencer is avoided.
Description
Technical field
The present invention relates to engine art, relate to the silencing apparatus that can improve combustion gas screwed pipe rotary engine efficiency specifically.
Technical background
The explosive motor of prior art all employ discrete special silencing apparatus, and its effect is the pulsation by reducing exhaust pressure and decay exhaust pressure gradually, reduces exhaust sound and the Mars eliminated in waste gas and flame.Some silencing apparatus utilizes the heat of institute's waste air to make three-way catalytic converter be operated in more than 300 DEG C temperature, and outside harmful gas pollution on the environment contained by purification institute waste air, the heat of institute's waste air there is no other purposes.
Number of patent application 201410415779.3 1 kinds improves method and the device thereof of propeller for turboprop engine efficiency, which provide a kind of gas turbine engine, casing is cylindrical shape, turbine rotor is replaced by screwed pipe rotor, form combustion gas screwed pipe rotary engine, the flow direction generation continuous print of flow working medium in screwed pipe rotor screwed pipe is changed, and the energy that switching flows working medium has is mechanical work outputting power.
Combustion gas screwed pipe rotary engine, be connected with rotating shaft fore bearing sealed rotational at the bottom of the cup of cup-shaped object, rim of a cup and the screwed pipe rotor screwed pipe entry end solid of rotation face seal of cup-shaped object are rotationally connected, cup-shaped object is fixed on outer casing and forms a firing chamber with interior casing, and external compressor apparatus is connected with rotating shaft power and also connects and composes gas generator with firing chamber gas.
In this combustion gas screwed pipe rotary engine, outer casing is exactly be connected across the engine housing between combustion gas screwed pipe rotary engine bearings at both ends, high-temperature high-pressure fuel gas there is no directly contact motor outer cage, the flowing of working medium flows through the acting of screwed pipe rotor screwed pipe to discharge outward from firing chamber, there is the gap of certain distance between the cup shell of screwed pipe rotor and firing chamber and engine housing.Do not mention silencing apparatus in application documents and utilized waste-gas heat to raise the efficiency correlation technique.
Summary of the invention
The object of this invention is to provide the silencing apparatus that can improve combustion gas screwed pipe rotary engine efficiency.
The present invention is realized by following technical proposals:
The silencing apparatus of combustion gas screwed pipe rotary engine efficiency can be improved, comprise combustion gas screwed pipe rotary engine, the engine housing be connected across between combustion gas screwed pipe rotary engine bearings at both ends is connected with rotating shaft sealing, the engine housing of the cup shell end of firing chamber is provided with relief opening, the waste gas of discharging from screwed pipe rotor is discharged to relief opening along the Clearance Flow formed between the cup shell and engine housing of screwed pipe rotor and firing chamber.
Be provided with a restrictor ring in engine housing, waste gas throttling speed-raising pressure-raising position, just to the rotary seal link position of the cup shell of screwed pipe rotor and firing chamber.
Owing to have employed abovementioned technology, the present invention obtains following technique effect:
1, the silencing apparatus that combustion gas screwed pipe rotary engine own structural characteristics forms a disjunctor is taken full advantage of.
2, this silencing apparatus can utilize waste-gas heat to improve combustion gas screwed pipe rotary engine efficiency.
3, eliminate discrete silencing apparatus, reduce motor cost.
Accompanying drawing explanation
Be described further below in conjunction with accompanying drawing.

In figure, 1. rotating shaft, 2. rotating shaft fore bearing, 3. casing in cylindrical shape, 4. firing chamber, 5. outer casing, 6. rotor solid of rotation, 7. rotating shaft rear bearing, 8. screwed pipe relief opening, 9. screwed pipe, 10. sealed rotational tie point, 11. cup-shaped objects, 12. silencing apparatus relief openings, 13. gas compressors.
Embodiment
The present invention is further illustrated below:
The silencing apparatus of combustion gas screwed pipe rotary engine efficiency can be improved, comprise combustion gas screwed pipe rotary engine, the engine housing be connected across between combustion gas screwed pipe rotary engine bearings at both ends is connected with rotating shaft sealing, the engine housing of the cup shell end of firing chamber is provided with relief opening, the waste gas of discharging from screwed pipe rotor is discharged to relief opening along the Clearance Flow formed between the cup shell and engine housing of screwed pipe rotor and firing chamber.
The present invention takes full advantage of the silencing apparatus that combustion gas screwed pipe rotary engine own structural characteristics forms a disjunctor.Combustion gas screwed pipe rotary engine is the axial-flow turbine of continuous operation, and air-flow is relatively smooth-going, so can not send similar reciprocating engine exhaust gas pulses sound.Waste gas always exceeds atmospheric temperature and lower than the temperature of high-temperature fuel gas from screwed pipe relief opening to the temperature of silencing apparatus relief opening, under the effect of hot kinetic potential, the heat flow Φ of high-temperature fuel gas can spontaneously pass through screwed pipe rotor top layer---waste gas layer---casing layer---atmospheric layer transmission, they have constituted the heat exchanger that has two shells in fact.In three kinds of basic heat exchange modes, no matter heat transfer, thermoconvection or thermal radiation, heat flow Φ is directly proportional to temperature difference Δ T, as with T
1represent high-temperature fuel gas temperature, use T
2represent the temperature of waste gas, use T
3represent atmospheric temperature, T
1-T
2temperature difference be obviously less than T
1-T
3temperature difference, so, temperature difference Δ T reduces by how many times of heat flow Φ and just reduces how many times, the strong dissipation stopping high-temperature fuel gas heat flow Φ, thus energy saving, this silencing apparatus can utilize waste-gas heat to improve combustion gas screwed pipe rotary engine efficiency in other words.The heat of waste gas plays insulation effect, provides heat flow to dispel the heat to shell simultaneously.
Be provided with a restrictor ring in engine housing, waste gas throttling speed-raising pressure-raising position, just to the rotary seal link position of the cup shell of screwed pipe rotor and firing chamber.It utilizes to reduce pressure difference between high-temperature fuel gas and waste gas two fluid to reduce the leakage rate of rotary seal.
