Abstract

The present invention is a system for generating power by using a gas having low boiling point (solvent) using low temperature heat (geothermal heat, solar heat, air heat, low temperature fuel combustion heat) and the like. In other words, it uses the same principle as the OTEC (Seawater Temperature Difference Generator), which makes two temperature differences on the land, heats the fruit on the higher side, obtains high pressure, drives the volumetric turbine at that pressure, generates power, and the fruit gas has the lower temperature. In the condenser, the fruit liquefies condensation. At this time, the condensed liquefied gas is sucked into the liquid pump installed inside the turbine and sent to the fruit gas heater to heat the fruit to increase the pressure, and then rotate the turbine to generate power. In order to make such a device, a two stage tricoid pump combined with an efficient expansion turbine and a high suction power pump is required to use a skin pump as an expansion turbine and an internal pump to transfer liquid to a liquefied gas pump. .

In addition, in order to increase the efficiency of the device, the heating part is heated to about 50 ° C, and when the outside air is low, the fruit gas is condensed to the low temperature of the outside air. Due to the characteristics of Korea's temperature, geothermal heat is always constant (average 15 ℃ ~ 18 ℃), and in winter, the temperature decreases from -5 ℃ to -20 ℃, so it becomes more efficient as the temperature goes down. (Such as winter, the critical temperature 132.4 ℃ The pressure of the critical temperature of 31 ℃ The pressure 75.3kg / cm ^2, the geothermal the ammonia gas 15 ℃ when the pressure is 51kg / cm ² during the summer of the carbon dioxide and write 115.2k / cm air When the temperature is 30 ℃, the pressure of ammonia gas is 11,89kg / cm ^{2 When the} geothermal temperature is 15 ℃, the pressure is 7.4kg / cm ² ).

Since the present invention consumes more fuel than a room that generates power by using a high pressure liquefied gas with low boiling point in order to generate power by using geothermal air heat and waste heat of waste heat. It is a power generator using high pressure liquefied gas. For example, ammonia (NH ₃ ) is used to heat waste heat (in an incinerator boiler exhaust heat and hot water using it) by heating a high pressure gas at about 80 ° C to operate the turbine at a high pressure (40 bar) gas pressure. Rotate and develop. After generating electricity by rotating the generator connected to the turbine shaft, the high-pressure gas exiting the turbine outlet is condensed into high-temperature gas (about 20 ℃) with the heat of the outside air in an outdoor air heat exchanger installed outside, and the pressure is about 9 By using the pump inside the turbine, the high pressure liquefied gas is transferred to the heat exchanger at high pressure by using a pump inside the turbine. At this time, the pump, such as the rotation of the turbine, is driven without any power, and the trocoidal gear rotor integrated with the turbine has two stages. As the outside is a turbine, the inside is a pump, so if the turbine rotates, the pump will also rotate. Although there are many Rankine cycle power plants using water, Rankine cycles using high pressure gas have never been used due to the accuracy of equipment and leakage of shaft, but it is currently 5 Kw / h due to the unique turbine of the present invention and the high pressure liquefied pump installed therein. It is a test run at the class, and there is no breakdown of the turbine due to the drastic saving of fuel and liquid intake than water use, and the pressure differential pressure is 10 to 15 bar with a pressure differential of 10 to 15 bar and a hose length of 1.5 m to 10.000 rpm to 3 to 5 Develops to Kw / h.

3 shows the structure of a two-stage tricoidal expander and a pump. The trocoidal gear has been developed since 80 years ago, and has been widely used as a hydraulic and lubricating oil pump to date. It consists of an outer gear and an inner gear, and the number of teeth of the outer gear is greater than the number of teeth of the inner gear. Pockets are formed between them, and the central axis of the inner gear is eccentric. When a force is applied from the outside to the central axis of the inner gear, the outer gear is applied by the rotation of the inner gear to transmit the rotational force to the outer gear.The rotation of the inner and outer gears narrows the widest pocket in the direction of rotation. If the port is installed on the outer cover and the discharge port is attached to the outer cover at the narrowest part and rotates continuously, the outer gear and the inner gear are attached and the teeth of the inner gear enter between the hops of the outer gear. It is sucked out and discharged into the narrowed part.
The present invention is made of two gear pumps by putting one of the trocoidal gears again inside the trocoidal gear as described above, and the second gear of FIG. 3 becomes the inner gear of the outer gear and the outer gear of the inner gear pump. As it is used simultaneously, the gear installed on the outside is used as a turbine, and the gear pump inside is used as a pump, so the turbine and the internal pump are united in one unit, so the outside is used as a turbine and the inside is used as a pump. 3 is the inlet of the turbine and the outlet of the turbine is exhausted to No. 8, the inlet of the inner pump is No. 5 and the outlet is No. 9. Injecting the high pressure gas pressure 15 bar at the first time rotates the inner and outer gears by volume expansion, and the gas is discharged to the eighth and the rotational force is generated and the inner pump rotates together. The above describes the structure and method of operation of the turbine and pump and operates at 15.000 rpm under no load as a result of the current test.
1 shows the appearance of a two-stage trocoidal. No. 3 outdoor condenser of FIG. 1 can increase condensation efficiency by using a water-cooled horizontal shell-and-tube type heat exchanger to increase the structure or efficiency of an air conditioner outdoor unit. Heat exchanger No. 4 of FIG. 1 can directly pass waste heat, and also increase the temperature (about 80 ° C) and pressure (about 40 bar) of the gas by using hot water, and inject gas gas into the turbine by heating the liquefied high pressure gas. Let's do it. In the actual operating situation, first vacuum the inside of the device, inject high-pressure gas ammonia or freon gas into the inside, check the proper amount, and then inject hot water or waste heat into the hot water and waste heat supply No. 7 in Fig. When passing through the hot water and waste heat outlet to increase the internal pressure to 30 bar, the high pressure gas gas enters the turbine gas inlet 9 and discharges to the turbine gas outlet 10 while rotating the turbine and the internal pump to rotate the generator connected to the shaft to generate electricity. . The gas gas exiting from the turbine gas outlet 10 is 15 bar and enters the 3rd outdoor liquefied gas condenser, exchanges heat with the outdoor unit, liquefies, enters the inlet of the 11th liquefied gas pump, and is discharged into the 12th liquefied gas pump outlet. After entering the liquefied gas heater no. 4 above 30 bar, it is heated and pressurized with hot water and waste heat to enter the turbine again to generate power.
