Abstract

A hydroelectric power generation method using low temperature boiling media is provided to rotate the turbine without heat loss of gas. A hydroelectric power generation method using low temperature boiling media isolates an upper tub(3), a turbine generator and a lower tank(4) from the atmosphere and adheres an automatic opening and closing unit are to a pipe in which the water and gas are delivered. A gas of which the pressure rises in a gas expansion chamber(17) flows into the lower tank when the water was run over in the lower tank and a turbine(2) is rotated by the pressure which is pressurized by the pressure(atm). The gas of the lower tank inside moves to a condensing chamber(18) and is converted to the liquid by being condensed after the pressurized water comes off. The gas of which the pressure(atm) rises again is supplied to the lower tank since the pressure(atm) rises with the heat exchange. The water in the upper tub is automatically provided to the lower tank when the water flows off.

The whole can be vacuumed to allow water to boil at low temperatures and to push the water to its vapor pressure to reverse the aberration. The first method can produce high pressure, so the output is high. In detail, a large cylinder is enclosed outside the upper tank, and the upper tank holds water. It releases the air pressure in the lower tank to allow water to flow from the upper part to the lower part. The valve is opened by itself by the hydraulic pressure of the upper tank and closes when the hydraulic pressure in the lower tank is lower than the hydraulic pressure in the upper tank. The air in the upper tank is also drained out and the lower tank is drained of water and the low temperature boiling medium is kept at the same pressure as the minimum pressure in the condensing chamber. When heat is first applied to the low temperature boiling medium in the expansion chamber, the low temperature boiling medium receives heat to increase the atmospheric pressure. When the water is filled in the lower tank, when the water is filled, the valve is opened by the automatic opening and closing device by the sensor, the gas in the expansion chamber flows into the upper part of the lower tank, and the pressure is applied to the whole water. The valve is opened by an automatic switchgear connected to the upper sensor. The water under the gas pressure kicks out and turns the aberration. The temperature of the water is set to approximate the temperature of the gas. Although not shown in the drawings, a separate heat exchanger and water may be connected to each other. When the water under pressure turns aberrations, water accumulates in the upper tank, and after the water rises, the automatic switchgear connected to the lower sensor is attached to close and open by the lower sensor in the tank. In other words, the automatic switchgear is connected to the upper sensor and lower sensor.

Condensation occurs in the condensation chamber. In order to condense, there must be a heat exchanger like the expansion chamber, and cold water can be condensed out of the heat exchanger. When heat or cold is applied to the heat exchanger during expansion or condensation, heat or cold can be applied using solar heat or ground water. Alternatively, the heat pump can be used to heat up and take away the heat. Heat can be removed by surrounding the water outside the heat exchanger and placing the evaporation tube of the heat pump. Heat transfer can be easier by placing the evaporation tube or condenser of the heat pump in the condensation or expansion chamber. The advantage of the heat pump is that the cop is high, which can greatly reduce the power compared to heat or cold generation. The low temperature boiling medium liquefied in the condensation chamber is transferred to the expansion chamber with a pressure pump, which receives heat from the expansion chamber and expands it. will be.

The main power generation has a great advantage in that there is much heat loss when the gas is turned on the turbine right away, and if there is only low temperature heat, it is possible to use hydropower at 3,4 atmospheres by using cold water such as groundwater. The use of a pump allows for more efficient power generation: the upper tank and the Haku tank are thermally insulated for heat preservation. The water does not lose heat to the outside, so that it is almost the same as the gas temperature to pressurize the tank water so that the air pressure is transferred to the water as it is. On the other hand, when the water in the tank runs out, the aberration stops, so to avoid this, connect the lower tank with a separate rice cake-like sensor and switchgear to the upper tank so that the other water can go out when one water runs out. (6) and (6) in the drawing are drawn with this in mind.

In the above process, the sensor device may take the manner of automatically opening and closing the valve by the time interval without the upper sensor lower sensor.
