Pneumatic water turbine

Abstract

The invention discloses a pneumatic water turbine. Water serving as a working medium of the pneumatic water turbine acquires energy through high-pressure gas. The pneumatic water turbine belongs to the technical field of energy and power. An energy converter of the pneumatic water turbine comprises two gas-liquid working cylinders, each of the gas-liquid working cylinder divides a sealing cylinder into a gas cavity and a water cavity through a piston, a connecting shaft penetrates through a sealing filler box, enters the water cavity and connects pistons of the two gas-liquid working cylinders, a solenoid valve is used for controlling energy of compressed air in a high-pressure gas tank to produce pressure water to push the water turbine, and part of the energy of the compressed air is used for pushing a gas turbine. High-pressure air expands slowly in the gas cavity, external heat is absorbed fully, an air working medium approaches isothermal expansion, the energy utilization rate of the high compression air is improved greatly, by the aid of high-efficiency energy conversion of the water turbine and most of available energy which is converted by the gas turbine from exhaust, and the whole system is free from throttling loss of the high-pressure air, gas leakage loss and tail gas loss, so that the efficiency of the whole water turbine is higher than that of an existing pneumatic motor.

Description

technical field [0001] The invention relates to a pneumatic water turbine whose working medium, water, obtains energy through high-pressure gas, and belongs to the technical field of energy and power. Background technique [0002] With the development of the automobile industry, energy and environmental protection issues have become increasingly prominent, and the research on clean alternative energy has generally attracted great attention all over the world. The development of electric vehicles is currently encountering bottlenecks due to the restriction of cruising mileage, battery life and waste pollution. The study of pneumatic engines has recently aroused great interest and has made great progress. The specific energy of compressed air is comparable to that of ordinary batteries. The air engine can be used as a real zero-emission engine. The inflation time is very short and safe. The air engine has a long life. The application of carbon fiber materials ensures the safe...

Problems solved by technology

[0005] 2. Gas leakage loss: Although the leakage loss is small in the total loss, it will increase rapidly with the increase of the leakage coefficient

[0006] 3. Exhaust gas loss: due to the relatively small expansion of the pneumatic engine and the high exhaust pressure, a large amount of energy is lost. At the same time, the expansion process is an adiabatic process, so the loss during exhaust emission accounts for nearly 50% of the total.

[0007] Therefore, the energy actually used to do external work is less than 1 / 3. Considering the efficiency of the engine working in different working conditions, the overall energy utilization rate of high-pressure gas is less than 15%.
