Description
The present invention is a power generation system with significantly improved efficiency, durability, and economic efficiency compared to a steam turbine using a conventional heat source, and heats oil continuously circulated inside the power generation system using a heat source of 100 degrees or higher to vaporize a screw-type turbine device. The oil heating gasifier, the high pressure circulation passage, and the device for cooling and condensing the gasified oil continue to circulate and generate electricity by turning the generator using the force to pass through.
The existing cogeneration poses the following problems.
1. The problem of high cost of installation cost
2. The problem of not applying a small heat merge system
3. Problems with the use of large-capacity facilities and large-scale energy using large-capacity steam
4. It is unreasonable to general incineration facility because it needs equipment to maintain constant temperature.
5. Difficulties in applying heat sources generated by each process of industrial facilities
6. Lack of environmental adaptability, which is only partially applied to processes in certain industries
7. Only high temperature power generation
The present invention implicitly presents a problem as mentioned above, but utilizes all of the discarded heat sources from homes to large industries as a future growth power source, and the present invention is the most suitable technology at the present time to save fossil energy.
The present invention has been drawn in view of the above-mentioned conventional problems, and its purpose is to utilize heat energy from home to industry according to the purpose and to use electricity generated by using heat generated in the atmosphere as before, and to use electricity once again. System.
The heat source is generated by using a direct heat source that utilizes direct energy such as a heat source using a solar heat collecting plate, waste heat to be discarded, and a burner, using a heat source according to the purpose of each process, and once again passing the heat source passing through the pipe. By continuously installing the system of the present invention operating in parallel to the exhaust gas discharged to the final stack, the oils in the circulation pipe reacting with the gas and the liquid for each temperature range are modified to maximize the use of the exhaust gas. Provide a method for use.
The present invention for achieving the above object is a circulating oil of the internal device using a heat source, that is, the kinetic energy of turning the screw turbine in gasification and reducing it to a high temperature liquid through a cooling condenser again. It is configured in a circular manner to return to.
In addition, the energy converted from the kinetic energy of the gas turbine to the screw turbine is converted into the necessary electrical energy by operating the generator connected to the coaxial shaft, so that the alternating current can be used.
In addition, when the first heat source is viewed as 100, the temperature of each heat source to the exhaust gas that is used as energy in a home or industrial line and is discharged to the final atmosphere through piping is about 20 inwards.
In view of this, considering the change in the heat source temperature passing through the smoke discharge pipe, the internal circulation oil of the power generation system of the present invention is made into a system that changes various types of oils that differ from the standards of reaction from liquid to gas for each temperature. Configure to make
Gas converted into kinetic energy to be turned into a screw turbine must be returned to a high temperature liquid after turning the skew turbine, and to minimize the size and installation cost of the system of the present invention by using a heat conduction cooling element as a device to cool it. Configure it to be possible.
In the conventional case, it is possible to reduce an excessive amount of separate water facilities and installation costs by using cooling water.
As described above, the power generation system using heat sources such as waste heat and solar heat can significantly reduce the functionality, applicability, and cost by complementing the disadvantages of the existing system.
1. Low cost investment of installation cost
2. Small cogeneration system possible
3. Best environmental adaptability to parallel facilities from small to large facilities
4. Applicable to general small-scale and large-scale incineration plants using waste heat discarded or process intermediate heat
5. Application of heat source generated by each process of industrial facility becomes easy
6. Applicable to all industrial processes
7. Both low temperature and high temperature power generation
In particular, in the case of biogas plant that uses electricity and heat energy by fermenting and digesting organic wastes, the high cost investment is required so that the equipment facilities that process the biogas produced without purification can be used as it is. When the power generation system using heat sources such as waste heat and solar heat is found to be continuously invested in the maintenance cost of the facility, the entire process of biogas from the small-scale farmhouse biogas facility to the large-scale biogas plant is completed. Cogeneration is possible without the use of power generation and heat sources.
Hereinafter, with reference to the accompanying drawings of the power generation system using a heat source such as waste heat and solar heat of the present invention.
1 is a power generation processor of a power generation system using heat sources such as waste heat and solar heat according to the present invention.
Among the methods for making the first thermal energy, one or more heat energy sources such as solar heat collecting plate (1), discarded waste heat (2), and direct heat source burner (3) are transferred to waste heat or steam pipe (L 1). Incombustible oil circulated from the oil gasification heating device (4) to the oil circulation pipe (L 5) passes through the oil gasification heating device (4), which is a heat exchanger, into a gaseous state of high pressure, and the gasification pipe (L 3). When the gas is passed along the screw turbine (5), the high-temperature, high-pressure gas energy is changed to the original kinetic energy to drive the generator (6) to generate electricity to reproduce and use electricity at home or industrial sites.
The gas energy assisted by the kinetic energy in the screw turbine (5) passes through the gasification pipe (L 4) and enters the cooling and condensation unit (7), and the gas energy is converted back into the high temperature oil of the liquid. The heat conduction cooling element 8 is used to change the liquid oil at high temperature.
When the heat conduction cooling element 8 absorbs and cools the surrounding heat, the gas is liquefied and the cooling and condensing device 7 is used.
Condensation is transported along the high temperature liquid oil pipe (L 5) and is circulated back to the oil gasification heating device (4), which is a heat exchanger.
When thermal energy is used for other purposes than power generation, ie, heating, other production processes, the energy transferred to waste heat or steam pipe (L 1) passes through the oil gasification heating device (4), which is a heat exchanger, to waste heat or steam pipe (L). Use 2) to make thermal energy available for other purposes.
1 is an explanatory diagram illustrating the principle of a power generation system using heat sources such as waste heat and solar heat according to the present invention.
Figure 2 is an embodiment of applying a power generation system using a heat source of waste heat and solar heat lamp of the present invention
3 illustrates an example of a conventional cogeneration method.
