Description
Technical field
The present invention relates to a kind of Pneumatic water turbine, its working medium water is obtained energy by pressurized gas, belongs to the energy and power engineering technical field.
Background technique
Along with the development of automotive industry, the energy and environmental issue become increasingly conspicuous, and the research of cleaning alternative energy source generally attracts great attention all over the world.The development of electric motor car is because life-span of the cruise restriction of mileage and storage battery and scrap pollution problem and run at present bottleneck.The research of air motor causes the very big interest of people recently, has a great development.Compressed-air actuated specific energy is equally matched with general battery, air motor can be used as Zero released engine truly, the very short and safety of inflationtime, the air motor life-span is very long, the application of carbon fibre material is protected the Security of pressurized gas automobile, but the poor efficiency of air motor makes again people that its application on automobile has been produced suspection.
Air motor mainly contains reciprocating piston type, blade type, rotary-piston type etc., and no matter its energy loss of motor of that a kind of structural type comprises:
1. restriction loss: the loss that the high-pressure pressure-reducing valve throttling produces accounts near 1/5 of total amount.And the raising with Pressure reducing ratio increases.
2. Leakage Gas loss: although leakage loss is less in the total amount of loss, will increase rapidly with the increase of leadage coefficient.
3. tail gas loss: because that air motor expands is smaller, the discharging of tail gas pressure is higher, has lost a large amount of energy, and inflation process is adiabatic process simultaneously, so the loss during exhaust emissions accounts near 50% of total amount.
Therefore, the real externally energy shortage 1/3 of acting that is used for is considered engine operation in the efficient of different operating modes, generally the capacity usage ratio less than 15% of pressurized gas.If consider the pressure that the pneumatic motor need of work is certain, the residual gas that leaves so certain pressure in the high pressure gas holder occupies again part energy.Although this part energy is loss not very, have a significant impact for the mileage that cruises of automobile.
Summary of the invention
The object of the invention is to design a kind of Pneumatic water turbine, allow the energy transmission of pressurized gas feed water, the water that obtains energy promotes the water turbine acting, because turbine efficiency is very high, can reach 96%, because the pressurized gas speed of expansion slows down, make it be arranged from extraneous absorbing heat, near isothermal expansion the sufficient time again; Because its pressure difference is very little, lose without Leakage Gas in the air-water conversion process of energy; Will not reduce pressure by high-pressure air, so restriction loss is also very little; When the pressure pan Pressure Drop when a certain value, can directly drive gas-turbine.
The technical solution used in the present invention is: a kind of Pneumatic water turbine, and it comprises a high pressure gas holder, and it also comprises an enegrgy converter, a gas-turbine and a water turbine, and gas-turbine is provided with the gas-turbine rotor, and water turbine is provided with hydroturbine rotor; Described enegrgy converter adopts two gas-liquid clutch release slave cylinders, and each gas-liquid clutch release slave cylinder adopts piston that closed cylinder is divided into air cavity and water cavity, and coupling shaft passes gland packing box and enters water cavity the piston of two gas-liquid clutch release slave cylinders is linked together; Described high pressure gas holder is through the air cavity of solenoid valve employing pipeline connecting sealed cylinder, and the air cavity of closed cylinder adopts pipeline to connect the gas-turbine nozzle of gas-turbine through solenoid valve; Described water turbine is provided with water tank, and water tank is through the water cavity of one-way valve employing pipeline connecting sealed cylinder, and the water cavity of closed cylinder adopts pipeline to connect the water turbine nozzle of water turbine through one-way valve.
Described gas-turbine rotor and hydroturbine rotor are arranged on the same output shaft.
Described water tank is arranged on the lower housing portion of water turbine.
Described high pressure gas holder adopts pipeline to connect respectively the first air inlet electromagnetic valve of the first air cavity and the second air inlet electromagnetic valve of the second air cavity through the high-pressure air solenoid valve, the first exhaust solenoid valve of the first air cavity be connected the second exhaust solenoid valve of air cavity and adopt respectively pipeline to connect the gas-turbine nozzle.
