Abstract
Description
Technical Field
[0001] The utility model relates to the field of waste heat power generation, in particular to an ORC generator body cooling device. Background Art
[0002] Organic Rankine Cycle (ORC) is a Rankine cycle with low-boiling-point organic matter as the working fluid. Organic Rankine cycle power generation technology is an energy-saving and emission-reduction technology that recycles medium- and low-grade waste heat and converts it into high-grade electricity. ORC can make full use of waste heat and waste heat energy with a temperature of 90°C to 250°C from geothermal energy, biomass energy, gas turbine or internal combustion engine exhaust, industrial furnace flue gas, etc., with high thermoelectric conversion efficiency. It can be widely used in waste heat and waste heat recovery power generation in high-energy-consuming industries and equipment such as petrochemicals, steel, cement, building materials, glass, ceramics, fertilizers, chemicals, and ship internal combustion engines. Since the core magnetic levitation generator of the ORC power generation system will generate high temperature during system operation, the power generation efficiency will be reduced. Summary of the invention
[0003] The utility model provides an ORC generator body cooling device to solve the heating problem of the core magnetic suspension generator of the ORC power generation system. The heat of the generator is taken away by the expansion of the low-temperature working medium and the heat of the high-temperature working medium Freon enters the generator through the electromagnetic bearing.
[0004] The technical solution adopted by the utility model is as follows: an ORC generator body cooling device comprises a condenser, a high-pressure working fluid pump, an evaporator, a turbine turbine, and a magnetic levitation generator. The condenser, the high-pressure working fluid pump, the evaporator, and the turbine turbine are sequentially connected through a working fluid output pipe to form a working fluid circulation loop. The turbine turbine is connected to the magnetic levitation generator. The working fluid inlet of the high-pressure working fluid pump is also connected to a cooling and cooling working fluid inlet pipe, and the cooling and cooling working fluid inlet pipe is connected to a cooling and cooling working fluid inlet arranged on the magnetic levitation generator. An electromagnetic valve is arranged on the cooling and cooling working fluid inlet pipe. The magnetic levitation generator is also provided with a cooling and cooling working fluid outlet, and is connected to the condenser through a reflux pipe.
[0005] Furthermore, the solenoid valve is an electromagnetic thermal expansion valve.
[0006] Furthermore, a temperature and pressure sensor is arranged in the reflux pipe, and the solenoid valve automatically adjusts the opening degree according to the temperature and pressure sensor signals.
[0007] The beneficial effects of the utility model are as follows: the utility model allows a part of the working fluid to enter the electromagnetic thermal expansion valve through the cooling working fluid inlet pipe, and the working fluid with reduced pressure enters the magnetic levitation generator through the cooling working fluid inlet, and absorbs a large amount of heat generated by the magnetic levitation generator and the heat of the high-temperature and high-pressure gaseous working fluid entering the magnetic levitation generator body through the turbine turbine, thereby reducing the temperature of the generator body and enabling the magnetic levitation generator to generate electricity safely and efficiently; by adopting the electromagnetic thermal expansion valve, the opening degree of the electromagnetic thermal expansion valve can be automatically adjusted by the temperature and pressure of the working fluid in the reflux pipe, thereby automatically adjusting the flow rate of the working fluid, thereby automatically controlling the temperature of the generator body. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0009] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and carefully below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.
[0010] like Figure 1 As shown, the ORC generator body cooling device of this embodiment includes a condenser 1, a high-pressure working fluid pump 2, an evaporator 6, a turbine turbine 5, and a magnetic levitation generator 4. The condenser 1, the high-pressure working fluid pump 2, the evaporator 6, and the turbine turbine 5 are sequentially connected through a working fluid output pipe to form a working fluid circulation loop. The turbine turbine 5 is connected to the magnetic levitation generator 4. The working fluid inlet of the high-pressure working fluid pump 2 is also connected to a cooling working fluid inlet pipe 9. The cooling working fluid inlet pipe 9 is connected to a cooling working fluid inlet 7 arranged on the magnetic levitation generator 4. An electromagnetic thermal expansion valve 3 is arranged on the cooling working fluid inlet pipe 9. The magnetic levitation generator 4 is also provided with a cooling working fluid outlet 8 and is connected to the condenser 1 through a reflux pipe 10. A temperature and pressure sensor is arranged in the reflux pipe 10. The electromagnetic thermal expansion valve 3 automatically adjusts the opening degree according to the temperature and pressure sensor signals.
[0011] The working principle of the utility model is as follows: a low-temperature liquid working medium (Freon) comes out of a condenser 1 and is sent to an evaporator 6 through a high-pressure working medium pump 2. The working medium is heated by waste heat in the evaporator 6 and evaporates into a high-temperature and high-pressure gaseous working medium. The gaseous working medium drives a turbine 5 to do work, driving a magnetic levitation generator 4 to generate electricity. After the gaseous working medium passes through the turbine 5, its pressure and temperature are reduced. Under the action of the pressure difference, the gaseous working medium flows back to the condenser 1 and is condensed into a low-temperature and low-pressure liquid working medium. Before the high-pressure working fluid pump 2 delivers the low-temperature liquid working fluid to the evaporator, a portion of the working fluid enters the electromagnetic thermal expansion valve 3 through the cooling working fluid inlet pipe 9, and the working fluid with reduced pressure enters the magnetic levitation generator 4 through the cooling working fluid inlet 7, and absorbs a large amount of heat generated by the magnetic levitation generator 4 and the heat of the high-temperature and high-pressure gaseous working fluid entering the magnetic levitation generator body through the turbine turbine. After absorbing heat, the high-temperature gaseous working fluid returns to the condenser 1 through the cooling working fluid outlet 8 and the reflux pipe 10 and is condensed into a low-temperature and low-pressure liquid working fluid.

Therefore, it is to be understood that the present invention is not limited to the specific embodiments disclosed, and modifications and other embodiments are considered to be included within the scope of the appended claims. Although specific terms are used herein, they are used only in a general and descriptive sense and not for limitation.
