Description

Technical Field

[0001] The invention relates to a novel energy storage generator set in the field of energy storage generator sets in hydropower generation. Background Art

[0002] The existing hydroelectric power generation energy storage generator set is designed in advance when the hydropower station is built and designed to build a large enough water storage tank (called "lower tank" in the industry) downstream of the reservoir dam. When the reservoir releases water for power generation, the water from the turbine first flows into the "lower tank". After the lower tank is full, it is discharged downstream. During the peak period of power consumption in the power grid (reservoir), the hydropower station normally generates electricity and distributes it to the power grid. When the power grid is at a low point, the hydropower station uses the surplus electricity on the power grid to pump the water in the lower tank back to the high level of the reservoir and store it in the reservoir. When the power grid is at a peak period, the water is released to generate electricity and send it to the power grid. We all know that the electricity used to pump the water in the lower tank back to the reservoir is much more than the electricity generated by the same amount of water (there is energy loss in this process). This is also a disadvantage of the energy storage power station, and the cost is increased when the construction requires additional investment. Summary of the invention

[0003] The purpose of the present invention is to use a new type of energy storage generator set to use heat energy to replace water pumps to send the water after power generation back to the high level before power generation without consuming electrical energy. This solution can generate hydroelectric power without building a reservoir, and can be used to generate electricity in almost any place with heat sources (including: waste heat from production, waste heat, hot rock geothermal heat, and solar energy).

[0004] The purpose of the present invention is achieved in this way: the natural circulation boiler that is currently the most widely used in countries around the world refers to a boiler evaporation system that uses the density difference between the water in the downcomer and the steam-water mixture in the riser as a driving force to establish a circulating flow of the working medium (also known as water circulation). See "Natural Circulation Boiler - Baidu Encyclopedia - Popular Science China Science Encyclopedia". The flow pressure head of water in a natural circulation boiler is very small. In order to solve this problem, we have designed a new technical solution that can make the liquid in a closed-loop annular pipeline use heat to allow the liquid to circulate naturally clockwise to drive the hydro-generator to generate electricity. This solution is based on Figure 3 The new energy storage generator set process flow diagram is completed in the device.

[0005] exist Figure 3The evaporator (1), the heater (2), the vapor-liquid separator (3), the lower transverse pipe (5) and the water turbine (6) form a closed loop annular pipe. After the liquid in the evaporator (1) is heated by the heat source, a certain easily vaporizable liquid sent by the feed pump (27) is vaporized by the vaporizer (30) and then enters the evaporator (1) through the feed valve (12) to instantly form a vapor-liquid mixture with the liquid in the evaporator (1) with a very low density. Although the temperature of the liquid in the heater (2) is the same (similar) to the temperature of the original liquid in the evaporator (1), since no bubbles are generated, a large density difference is generated in the vertical pipes on both sides, thereby driving the liquid in the annular pipe to flow clockwise, thereby driving the water turbine (6) at the right end of the lower transverse pipe (5) to drive the generator (7) to generate electricity. After the vapor-liquid mixture in the evaporator (1) flows to the vapor-liquid separator (3) above, bubbles overflow from the liquid and enter the exhaust pipe (4), are introduced into the condenser (8) through the pipeline, are condensed into liquid by cold water, and then enter the condensate collecting tank (20), and then are sent to the vaporizer (30) through the feeding pump (27), are vaporized, and then enter the bottom of the evaporator (1) through the feeding valve (12), forming a steam cycle. The vapor-liquid mixture in the evaporator (1) flows into the vapor-liquid separator (3) driven by the density difference. After the bubbles overflow, the liquid flows into the right heater (2) and then flows into the turbine (6) connected to the right end of the lower horizontal pipe (5), drives the generator (7) to generate electricity, and then flows into the evaporator (1), completing the liquid cycle. In the whole process, the amount of bubbles in the left vertical pipe evaporator (1) determines the size of the density difference. The amount of bubbles is determined by the amount of gas entering the evaporator (1) and is controlled by the feeding pump (27) and the feeding valve (12). The whole new energy storage generator set has a simple structure and low cost. It can be built into large, medium and small units. It has a wide range of heat source temperature requirements and can be applied to a variety of heat sources, such as factory waste heat, rock heat, solar energy and various fuels. There are many kinds of liquids that are easy to vaporize, such as ammonia, methanol, pentane, isopentane, butane, etc., and the variety is generally selected according to the temperature of the heat source. This solution can play a good role in solving air pollution and thermal pollution and reducing carbon emissions.

[0006] In order to make the specification more fully disclosed, we use four small experiments below to illustrate the process principles of the present invention.

[0007] Experiment 1

[0008] We use the attached Figure 1 A glass U-shaped tube with a stopcock at the bottom is used to perform a simple common sense experiment:

[0009] 1 First close the stopcock 1 under the U-shaped tube

[0010] 2 Pour water of the same height into the left and right vertical pipes to the middle of the U shape

[0011] 3 Open the stopcock 1

[0012] We observed that the water in the left and right vertical tubes of the U-shaped tube is motionless, and the two liquid levels are still at the same height. This is because the pressure on both sides of the U-shaped tube at the stopcock point 1 is equal, so the left and right liquid levels do not change.

[0013] Experiment 2

[0014] Let's pour out the water and do the following experiment:

[0015] 1 First close the stopcock 1 under the U-shaped tube

[0016] 2 Pour water into the left vertical pipe to the middle

[0017] 3. Pour mercury into the right vertical pipe until the water level is the same as the left vertical pipe.

[0018] 4 Open the stopcock 1 and we observe that the liquid in the two tubes flows. The mercury in the right vertical tube flows to the left vertical tube. When the liquid on both sides flows to a certain position, it stops flowing and the liquid level stabilizes at a fixed position. The liquid on both sides flows because the density of the liquid in the left vertical tube is different from that in the right vertical tube, resulting in a pressure difference at point 1. The pressure of the mercury in the right vertical tube at point 1 is greater than the pressure of the water in the left vertical tube at point 1 due to the high density of mercury, so the mercury in the right vertical tube flows to the left vertical tube. When the liquid flows to a certain position, the pressure at the intersection of mercury and water is equal, and the pressure on both sides reaches a new balance, so the liquid level stabilizes again.

[0019] This makes us think that if we can artificially create this imbalance in the left and right vertical pipes, and connect the top of the U-shaped pipe, the liquid in the pipe will continue to flow. The present invention can artificially destroy the balance in the U-shaped pipe to make the liquid in the pipe flow, so that the turbine drives the generator to generate electricity. So how can we make this imbalance continue to exist? Let's take a look at the third experiment.

[0020] Experiment 3

[0021] Attached Figure 2It is a U-shaped tube with a diameter of 0.04 meters, which is connected at the top. The diameter of the upper connecting part is 0.2 meters, and it has an exhaust pipe 3 at the top. An air intake pipe is installed under the left vertical pipe. The air intake volume is controlled by the air intake valve 1, and a small impeller is installed at 2. Experimental steps: 1. First connect the inlet of the air intake valve 1 to the micro air pump, and then inject water into the U-shaped tube from the exhaust pipe 3 to the bottom of the upper horizontal tube (the height of the left and right sides is the same). At this time, we can see that the liquid level of the left and right vertical tubes is stable. 2. Start of the experiment: Turn on the micro air pump, slowly open the air intake valve and gradually adjust the air intake valve 1, observe the amount of bubbles in the left vertical tube, so that the volume of bubbles in the left vertical tube gradually increases. At this time, we see that the bubbles are in the shape of steamed buns. Each bubble is holding a section of the water column above it and rising together. The bubbles separate the original continuous water column into multiple sections of non-continuous fluid, that is, bubbles and short liquid columns alternate. At the same time, there is water flowing in the upper connecting part of the U-shaped tube, and the two small impellers below the U-shaped tube are also seen rotating continuously. This proves that the water in the entire closed pipe flows clockwise from the right vertical pipe through the small impeller, then enters the left vertical pipe and then flows into the upper connecting pipe. The gas overflows from the liquid and is discharged through the exhaust pipe 3. The water finally flows back to the right vertical pipe and circulates continuously. As long as the air pump does not stop the water, it will continue to flow. Through this experiment, we discovered another characteristic of the fluid, that is, the liquid in the vertical pipe within a certain diameter range can cause the relative density of the liquid in the pipe to be greatly reduced by passing a certain amount of gas. It is this characteristic that allows us to make the pressure at 2 points on the left and right vertical pipes in Experiment 3 produce a pressure difference. It is this pressure difference that drives the liquid in the left and right vertical pipes to produce a clockwise circulation and drive the two small impellers below to rotate. The small-scale experiment can be industrialized and enlarged to make supporting equipment to drive the turbine to drive the generator to generate electricity.

[0022] Experiment 4:

[0023] We still use the attached Figure 2 Such equipment increases the pipe diameter of the entire equipment to 100mm, the height of the vertical pipe is made into 2 meters, and the diameter of the upper horizontal pipe is made into 200mm. Then repeat the experiment of Experiment 3. Before the experiment starts, water is added to half of the vertical pipe, that is, 1 meter high (the height of water in the two vertical pipes is the same), and then the inlet of the air inlet valve 1 is connected to the micro air pump.

[0024] Experiment starts:

[0025] Turn on the micro air pump, slowly open the steam inlet valve and gradually adjust the inlet valve 1, observe the amount of bubbles in the left vertical pipe, so that the volume of bubbles in the left vertical pipe gradually increases (increase the air intake). At this time, we can see that the liquid in the left vertical pipe is in a turbulent state under the action of a large amount of gas (the interface between water and steam can no longer be distinguished, which can be seen as a large number of extremely small bubbles mixed in water, or a large number of extremely small water droplets mixed in steam). The water level in the left vertical pipe has reached nearly 2 meters (at this time, the air intake should be controlled to prevent water from entering the upper horizontal pipe). At the same time, it is observed that the water level in the right vertical pipe still has a small fluctuation of 3 centimeters above and below at 1 meter. At this time, the 2-meter high water level in the left vertical pipe and the 1-meter high water level in the right vertical pipe are isobaric. In this state, we inject water from the exhaust port 3 to the right vertical pipe to a height of 2 meters. During the water injection process, it is found that the gas-liquid mixture in the left vertical pipe flows into the upper horizontal pipe while the two small impellers below are also rotating. When the water level in the right vertical pipe reaches 2 meters, the pressure difference between the right water pipe and the left vertical pipe is 1 meter. If this experiment is scaled up to a complete set of equipment, the clockwise flow of liquid in the system can drive the turbine to drive the generator to generate electricity.

DETAILED DESCRIPTION

[0030] The following is combined (attached Figure 3 ) Embodiment is further described in detail.

[0031] The embodiments include two examples of Experiment 3 and Experiment 4, which are described as follows:

[0032] 1. Combining the implementation example of Experiment 3

[0033] like Figure 3 As shown, before starting the new energy storage generator set, all valves are closed, then the overflow valve (15) is opened, tap water is connected to the liquid inlet valve (10), the liquid inlet valve (10) is opened, the return valve (26) is opened, the feed pump (27) is opened, the feed valve (12) is opened, the tap water switch is opened to inject water into the system, until water flows out of the overflow valve (15), the tap water switch is closed, the overflow valve (15) is closed, the liquid inlet valve (10) is closed, the return valve (26) is closed, the feed pump (27) is closed, the feed valve (12) is closed, carbon dioxide gas is connected to the inlet valve (13), the inlet valve (13) is opened to exhaust gas. Valve (16) opens the carbon dioxide gas main valve to fill the system through the air inlet valve (13), until the exhaust valve (16) has exhausted the water and exhausted the gas, then close the exhaust valve (16) (this water is discharged into the water reservoir), open the discharge valve (11), open the liquid inlet valve (23), open the liquid inlet pump (9), open the liquid inlet valve (24) to send the water in the condensate collection tank (20) into the evaporator (1), at this time there is no air (oxygen) in the system, close the air inlet valve (13), close the carbon dioxide main valve, close the discharge valve (11), close the liquid inlet valve (23), close the liquid inlet pump (9), and close the liquid inlet valve (24). Carbon dioxide gas is used here to discharge water and air because 1. Exhausting excess water allows the gas-liquid separator (3) to empty and make room for the gas-water mixture to be formed in the evaporator (1) during normal operation, so that the gas overflows from the liquid in the gas-liquid separator (3) and enters the exhaust pipe (4). 2. Because the steam of the easily vaporized liquid used is flammable and explosive gas, the air must be exhausted from the system to avoid accidents. The system can be officially started only after the turbine cranking is normal.

[0034] Start-up: Open the condenser cold water circulation system, open the condenser water inlet valve (18) and the condenser water outlet valve (19), inject hot steam (or hot liquid) into the coil connected to the heat source pipe (14) and the heat source inlet valve (28) and the heat source outlet valve (29), wait until the liquid (water) in the evaporator (1), the heater (2) and the vaporizer (30) reaches the required temperature (98°C) (this temperature depends on the properties of the liquid to be vaporized), connect the methanol liquid (under a standard atmospheric pressure, the boiling point of methanol is 64.5°C) through the liquid inlet valve (10), open the liquid inlet valve (10), open the reflux valve (26) and the feed valve (12), and simultaneously start the feed pump (27) to feed the methanol liquid into the vaporizer (30). Methanol is in the vaporizer (30) The hot water instantly vaporizes to generate a large amount of gas which enters the evaporator (1) through the feed valve (12) and sends a large amount of water in the evaporator (1) to the vapor-liquid separator (3) above. The continuity of the liquid in the evaporator (1) is destroyed, and the relative density of the water column between the vapor and liquid phases is only half of the original density (controlled by the amount of methanol converted into gas). The water in the right heater (2) still has the original density, which causes a large density difference between the liquid in the heater (2) and the evaporator (1). The size of this density difference depends on the height of the evaporator (1) and the heater (2) and the amount of methanol liquid added (i.e. the volume of the bubbles). The driving force of this density difference causes the water to flow clockwise in the system, driving the turbine (6) to drive the generator (7) to generate electricity. After the gas in the vapor-liquid separator overflows, it enters the condenser (8) through the exhaust pipe (4). When the condensate of the methanol liquid in the condenser (8) flows into the condensate collecting tank (20) and the liquid level reaches 0.5 meters, the discharge valve (11) is opened, and the inlet valve (10) is closed. The condensate methanol liquid is supplied by the feed pump (27) and pumped into the vaporizer (30). Under the action of the 98°C hot water in the vaporizer (30), the methanol liquid is instantly vaporized and enters the evaporator (1) through the feed valve (12), so that the liquid in the evaporator (1) is always kept in the state of vapor-liquid phase, and the relative density ratio between the evaporator (1) and the heater (2) is maintained at 1:2, so that the liquid in the system always flows clockwise. When the water and steam flow to the vapor-liquid separator (3) above, the gas overflows into the exhaust pipe (4) and the water flows back to the heater (2) and then drives the turbine (6) to drive the generator (7) to generate electricity and then flows back to the evaporator (1) to complete the water circulation. The gas in the gas-liquid separator enters the condenser (8) through the exhaust pipe (4) and is condensed into liquid methanol and flows into the condensate collecting tank (20), thus completing the methanol cycle. At this time, the system enters a normal cycle.

[0035] Next, we calculate the power generation capacity of the system with specific data: we set the diameter of the evaporator (1) and the lower horizontal pipe (5) of the heater (2) to 0.04 meters, the diameter of the exhaust pipe (4) to 0.2 meters, and the height of the vertical pipe to 40 meters.

[0036] The volume of gas produced by the addition of methanol is equal to the volume of water flowing. At this time, the pressure difference generated by the two liquids with different relative densities in the evaporator (1) and the heater (2) is 20 meters of water column. The flow rate of water in the heater (2) is

[0037] The cross-sectional area of ​​the tubes of the evaporator (1) and the heater (2) is s = π × 0.02 × 0.02 = 0.001256 m 2 .

[0038] Water flow rate in heater (2) = 0.001256 m 2 × 19.8 m / s = 0.0248688 m 3 / second is approximately equal to 24.8 kg / s. The output formula of the turbine is: P = gQH kilowatt g-gravitational acceleration Q-liquid flow meter 3 / sec H-liquid column (water head) m P = 9.81 m / sec 2 ×0.0248688m 3 / second x 20 meters = 4.876 kilowatts

[0039] 2. Combination with Experiment 4

[0040] As shown in the figure, before starting the new energy storage generator set, all valves are closed, and then the overflow valve (15) is opened. After tap water is connected to the liquid inlet valve (10), the liquid inlet valve (10) is opened, the return valve (26) is opened, the feed pump (27) is opened, and water is injected into the system through the vaporizer (30). After water flows out of the overflow valve (15), the tap water switch is turned off, the overflow valve (15) is closed, the liquid inlet valve (10) is closed, the return valve (26) is closed, the feed pump (27) is turned off, and carbon dioxide gas is connected to the inlet valve (13), the inlet valve (13) is opened, and the exhaust valve is opened. (16) Open the main valve of carbon dioxide gas and fill the system through the air inlet valve (13) until the exhaust valve (16) has exhausted the water and exhausted the gas, then close the exhaust valve (16) (this water is discharged into the water reservoir), open the discharge valve (11), open the liquid inlet valve (23), open the liquid inlet pump (9), open the liquid inlet valve (24) to pump the water in the condensate collection tank (20) into the evaporator (1), then close the discharge valve (11), close the liquid inlet valve (23), close the liquid inlet pump (9), close the liquid inlet valve (24), at this time there is no air (oxygen) in the system, close the air inlet valve (13), and close the main valve of carbon dioxide. Carbon dioxide gas is used here to discharge water and air because 1. Exhausting excess water allows the vapor-liquid separator (3) to empty and make room for the vapor-water mixture to be formed in the evaporator (1) during normal operation, allowing the gas to overflow from the liquid in the vapor-liquid separator (3) into the exhaust pipe (4). 2. Because the steam of the easily vaporized liquid used is flammable and explosive gas, the air must be exhausted from the system to avoid accidents. The system can be officially started only after the turbine cranking is normal.

[0041] Start-up: Open the condenser cold water circulation system, open the condenser water inlet valve (18) and the condenser water outlet valve (19), inject hot steam (or hot liquid) into the coiled pipe connected to the heat source pipe (14) and the heat source inlet valve (28) and the heat source outlet valve (29) to be vaporized in the tank (30), after the liquid (water) in the evaporator (1) and the heater (2) reaches the required temperature (60°C) (this temperature depends on the properties of the liquid to be vaporized), connect the n-pentane liquid (the boiling point of n-pentane at a standard atmospheric pressure is 27.8°C) through the liquid inlet valve (10), open the liquid inlet valve (10) and the reflux valve (26), open the feed valve (12) and start the feed pump (27) at the same time, feed the n-pentane into the vaporizer (30), the n-pentane is instantly vaporized in the hot water in the vaporizer (30) to generate a large amount of gas, which enters the evaporator through the feed valve (12). The liquid in the evaporator (1) is sent to the vapor-liquid separator (3) above. Under the action of a large amount of n-pentane gas, the liquid in the evaporator (1) forms a vapor-liquid mixture with a very low density in a turbulent state (the vapor-liquid mixture at this time has no obvious gas or liquid interface, that is, it can be regarded as a large number of fine bubbles evenly distributed in the water or a large number of small water droplets evenly distributed in the gas). The water in the right heater (2) still has the original density, which causes a large density difference between the liquid in the heater (2) and the evaporator (1). The size of this density difference depends on the height of the evaporator (1) and the heater (2) and the amount of n-pentane added (that is, the volume of the bubbles). The driving force of this density difference causes the water to flow clockwise in the system, driving the turbine (6) to drive the generator (7) to generate electricity. The gas in the vapor-liquid separator overflows from the liquid and enters the condenser (8) through the exhaust pipe (4). When the condensate of n-pentane in the condenser (8) enters the condensate collecting tank (20), the discharge valve (11) is opened when the liquid level reaches 0.5 meters, and the inlet valve (10) is closed. The condensate n-pentane is supplied to the feed pump (27) and pumped into the vaporizer (30). The n-pentane liquid is rapidly vaporized under the action of the 60°C hot water in the vaporizer (30) and enters the evaporator (1) through the feed valve (12), so that the liquid in the evaporator (1) is always kept in a turbulent state, and the relative density ratio between the evaporator (1) and the heater (2) is maintained at a state of 1 to 2, so that the liquid in the system always flows clockwise. After the vapor-liquid mixture flows into the vapor-liquid separator (3) above, the n-pentane gas overflows from the liquid and enters the condenser (8) through the exhaust pipe (4), is condensed into liquid and flows into the condensate collecting tank (20), thus completing the cycle of n-pentane. The vapor-liquid mixture in the evaporator (1) flows to the vapor-liquid separator (3), and the gas overflows from the liquid. The liquid then flows back to the heater (2) and flows into the turbine (6) at the right end of the lower horizontal pipe (5), driving the generator (7) to generate electricity, and then flows back to the evaporator (1), completing the circulation of the liquid (water). At this time, the system enters a complete normal cycle.

[0042] Next, we calculate the power generation capacity of the system with specific data: we set the diameter of the evaporator (1) and the lower horizontal pipe (5) of the heater (2) to 0.1 m, the diameter of the vapor-liquid separator to 0.2 m, the diameter of the exhaust pipe (4) to 0.2 m, and the height of the vertical pipe to 20 m.

[0043] The volume of gas produced by the addition of n-pentane is equal to the volume of water flowing. At this time, the pressure difference generated by the two liquids with different densities in the evaporator (1) and the heater (2) is 10 meters of water column. The flow rate of water in the heater is

[0044] The cross-sectional area of ​​the tubes of the evaporator (1) and the heater (2) is s = 3.14 × 0.05 × 0.05 = 0.00785 m 2 .

[0045] Water flow rate in heater (2) = 0.00785 m 2 × 14 m / s = 0.1099 m 3 / second is approximately equal to 110 kg / second

[0046] The output formula of the turbine: P = gQH kilowatt g---gravitational acceleration Q---liquid flow meter 3 / second H---Liquid column (water head) meter P = 9.81 m / s 2 ×0.11m 3 / second x 10 meters = 10.78 kilowatts

[0047] We all know that the efficiency of small turbines is lower than that of large turbines. Therefore, it is recommended that if you want to build a large power station, it is best to make the right side vertical pipe into a large diameter and the left side vertical pipe into several 100mm small diameter vertical pipes to improve the efficiency of the turbine.

The inlet valve (10) is unloaded. The inlet valve (10) is connected, the feed valve (12) is closed, the reflux valve (26) is closed, and the feed pump (27) is closed. Then, the carbon dioxide gas is connected to the inlet valve (13), the inlet valve (13) is opened, the exhaust valve (16) is opened, and the carbon dioxide main valve is opened. After the exhaust valve (16) has discharged the water and the gas is discharged, the exhaust valve (16) is closed. The drain valve (17) is opened. After the drain valve (17) has discharged the liquid and the gas is discharged, the drain valve (17) is closed. The discharge valve (11) is opened, the inlet valve (23) is opened, the inlet pump (9) is started, the inlet valve (24) is opened, and the liquid (water) in the condensate collection tank is pumped into the evaporator (1). Then, the discharge valve (11) and the inlet valve (23) are closed, the inlet pump (9) is closed, the inlet valve (24) is closed, the inlet valve (13) is closed, and the carbon dioxide main valve is closed. At this time, there is no air in the system and the conditions for starting operation are met.Taking the water and n-pentane system as an example, when the system is started, the condenser water inlet valve (18) and the condenser water outlet valve (19) are opened to charge the cold circulating water, and then the heat source inlet valve (21) and the heat source outlet valve (22) are opened to charge the heat source into the heat source pipe (14), and the heat source inlet valve (28) and the heat source outlet valve (29) are opened. When the water temperature in the vaporizer (30), the evaporator (1), the heater (2) and the lower horizontal pipe (5) reaches the required 60°C, the heat source is charged into the heat source pipe (14). After the temperature reaches 100 °C, the low-boiling-point gas generating agent n-pentane can be connected to the liquid inlet valve (10), the liquid inlet valve (10) is opened, the reflux valve (26) is opened, the feed valve (12) is opened, and then the n-pentane main valve is opened and the feed pump (27) is started. After the n-pentane liquid enters the vaporizer, it is heated and quickly vaporized to produce a large amount of gas, which enters the evaporator (1) through the feed valve (12). The feed valve (12) is slowly adjusted to allow the n-pentane gas entering the evaporator (1) to gradually increase. The amount of gas increases, causing the liquid density in the evaporator (1) to drop significantly, and a large density difference, i.e., a pressure difference, is generated between the evaporator (1) and the heater (2), causing the water in the system to flow clockwise, pushing the turbine (6) to drive the generator (7) to generate electricity. After the steam-water mixture flows to the steam-liquid separator (3), the gas overflows into the exhaust pipe (4) and enters the condenser (8) to be condensed and then enters the condensate collecting tank (20). When the liquid level in the condensate collecting tank (20) reaches half a meter, the inlet valve (10) is closed and the outlet valve (11) is opened. Then, the n-pentane condensate is passed through the feed pump (27) and the reflux valve (26) to enter the vaporizer to generate a large amount of gas, which is sent back to the evaporator (1) through the feed valve (12). After the steam-water mixture flows to the steam-liquid separator (3), the gas overflows and the water enters the heater (2), pushing the turbine (6) to drive the generator (7) to generate electricity and then enter the evaporator (1). The cycle is repeated repeatedly and the normal operation and power generation state is achieved.
