Description

Technical Field

[0001] The present invention relates to the technical field of nuclear energy heating, and particularly to a nuclear energy heating device and system. Background Art

[0002] Nuclear energy heating refers to using the waste heat of a nuclear power plant to provide heating for residents. A large amount of heat energy is generated by the nuclear fission reaction inside the nuclear reactor. This heat energy is usually used to generate steam to drive a turbine for power generation. A part of the heat energy that is not fully utilized in this process will be captured through a series of efficient heat exchange systems and transported to the urban heating network, so as to achieve the purpose of nuclear energy heating.

[0003] In the existing nuclear energy heating system, there is only heat transfer between the plant heat exchange station and the heat exchange main station of the heating company, and there is no water exchange. Although it can use district heating to reduce the temperature of the cold return water, the cold return water temperature of the heat exchange main station of the heating company is usually between 35°C and 50°C, while the water temperature in the plant heat exchange station is generally between 90°C and 120°C. The water temperature difference between the heat exchange main station of the heating company and the plant heat exchange station is relatively small. Under the same heat transfer amount, a larger water flow is required to maintain the heating effect, which will increase the energy consumption of the circulating water pump, not only increase the operation cost, but also reduce the energy utilization efficiency of the entire system. Therefore, we propose a nuclear energy heating device and system. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a nuclear energy heating device and system.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A nuclear energy heating device, comprising: A water pump, a cooling device and a water storage device. The water storage device includes a water storage tank for uniformly collecting warm water and a drainage block for quickly discharging the water in the water storage tank. A stirring mechanism for stirring the warm water is arranged inside the water storage tank. The cooling device includes a buffer tank communicated with the drainage block and several cooling mechanisms for secondarily cooling the warm water inside the water storage tank. A water guiding mechanism for providing power to the stirring mechanism is arranged below the cooling mechanism, and a water storage pool for storing cold water is arranged below the water guiding mechanism; The buffer tank is set in a funnel shape, and the water outlet of the drainage channel is arranged obliquely above the buffer tank. The water inlet pipe of the water pump is connected to the return water pipe of the general heat exchange station of the heating company. The water outlet pipe of the water pump extends into the interior of the water storage tank. A number of cooling mechanisms are arranged in sequence from top to bottom. The warm water in the general heat exchange station of the heating company is pumped into the interior of the water storage tank by the water pump, so that the warm water is uniformly collected and cooled in the interior of the water storage tank. When the height of the warm water stored in the water storage tank exceeds the height of the drainage block, the warm water in the water storage tank is quickly discharged into the buffer tank through the drainage block, and then the buffer tank conveys the warm water to a number of the cooling mechanisms for secondary cooling, turning the warm water into cold water. The kinetic energy generated when the cold water descends drives the water guiding mechanism to drive the stirring mechanism to rotate, so that the stirring mechanism stirs the warm water in the water storage tank, accelerating the release of heat energy of the warm water in the water storage tank. At the same time, the cold water flows into the storage pool after passing through the stirring mechanism.

[0006] As a preferred technical solution of the present invention, a top rod is fixed to the top of the drainage block, a top cover for supporting the water pump is arranged at the top of the top rod, and a drainage channel for discharging the warm water in the water storage tank is also arranged inside the drainage block. The bottom of the drainage channel penetrates through the water storage tank and extends into the interior of the buffer tank. A height gauge for observing the height of the warm water in the water storage tank is also arranged on the water storage tank. The top cover is set in the shape of a flat-topped cone, and a cavity is formed by the inward depression of the bottom of the top cover. The diameter of the bottom of the top cover is larger than the diameter of the water storage tank, so that the top cover can be sleeved above the water storage tank. After the water pump conveys the warm water into the interior of the water storage tank, the warm water in the water storage tank enters the interior of the drainage channel. When the height of the warm water in the water storage tank exceeds the drainage block, the warm water in the water storage tank is quickly discharged into the buffer tank through the drainage channel by atmospheric pressure.

[0007] As a preferred technical solution of the present invention, the cooling mechanism includes a heat dissipation cylinder installed at the bottom of the buffer tank. A number of heat dissipation holes are arranged on the outer wall of the heat dissipation cylinder. The number of heat dissipation holes are arranged annularly on the heat dissipation cylinder, and a number of heat dissipation holes are all inclined and communicated with the mounting block after being arranged on the mounting block. A clamping mechanism for splicing a number of cooling mechanisms is also arranged on the outer wall of the heat dissipation cylinder. The heat dissipation holes obliquely penetrate through the mounting block to prevent the warm water from splashing to the outside of the heat dissipation cylinder when flowing through the inner wall of the heat dissipation cylinder. At the same time, the warm water flowing through the interior of the heat dissipation cylinder can be quickly cooled through a number of heat dissipation holes, quickly cooling the warm water into cold water.

[0008] As a preferred technical solution of the present invention, the clamping mechanism includes a locking plate and a positioning plate fixed on the outer wall of the heat dissipation cylinder. A rotating shaft is provided at one end of the positioning plate away from the heat dissipation cylinder. A turning plate is provided on the rotating shaft. A counterweight is fixed on the top of the turning plate, and a secondary convex portion is provided at the bottom of the turning plate. A main convex portion adapted to the positioning plate is provided on the top of the locking plate, and the turning plate is arranged above the locking plate. The center of gravity of the turning plate can be changed through the counterweight, so that the counterweight drives the turning plate to rotate downward around the rotating shaft. By pushing one of the heat dissipation cylinders upward, one of the heat dissipation cylinders drives the cooperation of one of the main convex portions and the other secondary convex portion to limit one of the main convex portions, so that the two heat dissipation cylinders are spliced.

[0009] As a preferred technical solution of the present invention, a filter ring for blocking the heat dissipation holes is further arranged inside the heat dissipation cylinder. Two clamping blocks are symmetrically fixed on the outer wall of the filter ring. A clamping groove matched with the clamping block is opened on the heat dissipation cylinder. The heat dissipation holes can be blocked through the filter ring to prevent foreign objects outside from entering the heat dissipation cylinder through the heat dissipation holes and polluting the inside of the heat dissipation cylinder. And the filter ring can be quickly disassembled and assembled through the cooperation of the clamping block and the clamping groove.

[0010] As a preferred technical solution of the present invention, the water guiding mechanism includes an extension cylinder arranged below the cooling mechanism. A height rod is arranged inside the extension cylinder. A turbine rod is fixed in the middle of the height rod. A plurality of spiral blades are fixed on the outer wall of the turbine rod. And a support rod is arranged between the turbine rod and the water storage tank. The stirring mechanism is installed on the support rod. An annular groove for facilitating the rotation of the height rod is opened on the inner wall of the extension cylinder. Both ends of the height rod extend into the annular groove. One end of the blade away from the turbine rod extends outward to contact the inner wall of the extension cylinder. The kinetic energy generated when the cold water descends is used to push the spiral blades to drive the turbine rod to rotate, so that the turbine rod drives the support rod to rotate, and the support rod drives the stirring mechanism to rotate. Thus, the kinetic energy generated when the water descends is used to provide power for the water guiding mechanism, which can reduce energy consumption and save energy.

[0011] As a preferred technical solution of the present invention, the stirring mechanism includes a transmission rod fixed on the support rod. An inclined rod is arranged at one end of the transmission rod away from the support rod. One end of the inclined rod away from the transmission rod extends into the water storage tank and is fixed with a mounting block. A stirring blade for stirring the warm water is fixed at the bottom of the mounting block. The side of the stirring blade facing the transmission rod contacts the inner wall of the water storage tank. The inclined rod is obliquely arranged above the water storage tank. The top of the inclined rod extends into the cavity. The obliquely arranged inclined rod can prevent the condensed water in the air from flowing into the water storage tank through the inclined rod and polluting the warm water inside the water storage tank. When the support rod drives the transmission rod to rotate, the transmission rod drives the inclined rod to rotate. The inclined rod drives the stirring blade to rotate through the mounting block. The warm water inside the water storage tank is stirred by the stirring blade. At the same time, the inner wall of the water storage tank can also be cleaned by the stirring blade to prevent scale from forming on the inner wall of the water storage tank.

[0012] A nuclear energy heating system includes the following steps: Step 1: The heat generated by the reactor in the nuclear island heats the water in the conventional island into high-temperature and high-pressure steam through a steam generator, and part of the steam in the conventional island is extracted to heat the water in the plant heat exchange station; Step 2: The hot water of the plant heat exchanger in the plant heat exchange station exchanges heat with the water in the general heat exchange station of the heating company. Through the cooperation of the regulating valve and the heat exchanger of the general heating station in the heating company, the cold return water in the community heat exchange station is heated. The community heat exchanger in the community heat exchange station exchanges heat between the hot water and the water in the heating pipes in the user area; Step 3: After the hot water in the heating pipes in the user area releases heat energy, its temperature drops to become warm water. The cold water flows back to the heat exchanger in the community heat exchange station through the pipeline. The heat exchanger in the community heat exchange station exchanges heat energy of the warm water again, so that the warm water in the heat exchanger in the community heat exchange station exchanges heat with the water in the exchanger in the general heat exchange station of the heating company again; Step 4: The warm water inside the exchanger in the general heat exchange station of the heating company is pumped into the water storage device by a water pump. The water storage device uniformly recovers the warm water, preliminarily cools the warm water inside the water storage device. The cooled warm water is secondarily cooled by a cooling device to form cold water, and the cold water flows back into the plant heat exchanger in the plant heat exchange station to complete the heat energy exchange.

[0013] Compared with the prior art, the beneficial effects that the present invention can achieve are: Through the cooperation of structures such as a water pump, a cooling device, a water storage device, a drainage block and a drainage channel, the warm water inside the water storage tank is discharged from the drainage channel by using atmospheric pressure, so that the warm water is intermittently discharged and cooled through the drainage channel, reducing the temperature of the cold return water, thereby reducing the energy consumption of the circulating water pump, reducing the operation cost, and improving the energy utilization efficiency of the entire system.

[0014] Through the discharge of the cold return water inside the drainage channel, the cold return water enters the buffer tank, and the cold return water is discharged into the buffer tank and conveyed to the heat dissipation cylinder in a swirling manner, so that the cold return water in the buffer tank quickly enters the heat dissipation cylinder. After the heat of the cold return water in the heat dissipation cylinder is discharged to the outside of the heat dissipation cylinder through the heat dissipation holes, the cold return water in the heat dissipation cylinder is secondarily cooled, thereby further reducing the temperature of the cooling water flowing back to the plant heat exchange station.

[0015] Through the contact between the cooling water in the heat dissipation cylinder and the blades, the kinetic energy generated when the heat dissipation cylinder descends drives the blades to drive the turbine rod to rotate, accelerating the air flow velocity inside the extension cylinder by the rotating blades. This can not only create negative pressure inside the extension cylinder, but also reduce the temperature inside the extension cylinder, thereby increasing the drainage speed of the extension cylinder and further reducing the temperature of the cold return water.

[0016] The turbine rod drives the support rod to rotate, the support rod drives the transmission rod to rotate, the transmission rod drives the inclined rod to rotate, the inclined rod drives the mounting block to rotate, and the mounting block drives the stirring blade to rotate, so as to stir the water stored inside the water storage tank. Thus, when the water storage tank stores water, the temperature inside the water storage tank can be reduced, the heat dissipation efficiency of the water storage tank during water storage can be improved, and the inner wall of the water storage tank can also be cleaned by the stirring blade to prevent scale from generating inside the water storage tank.

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0020] Embodiment: The present invention is as Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10A nuclear energy heating device as shown, including a water pump 7, a cooling device 8 and a water storage device 9. The water storage device 9 includes a water storage tank 901 for uniformly collecting warm water and a drainage block 904 for quickly discharging the water in the water storage tank 901. Inside the water storage tank 901, there is a stirring mechanism for agitating the warm water. The cooling device 8 includes a buffer tank 801 connected to the drainage block 904 and several cooling mechanisms for secondary cooling of the warm water inside the water storage tank 901. Below the cooling mechanisms, there is a water guiding mechanism for providing power to the stirring mechanism. Below the water guiding mechanism, there is a water storage pool for storing cold water. The buffer tank 801 is set in a funnel shape, and the outlet of the drainage channel 906 is set obliquely above the buffer tank 801. The water discharged through the drainage channel 906 flows into the interior of the funnel-shaped buffer tank 801, enabling the water inside the buffer tank 801 to be discharged in a swirling manner, which can improve the drainage speed of the buffer tank 801. The inlet pipe of the water pump 7 is connected to the return pipe of the general heat exchange station 4 of the heating company, and the outlet pipe of the water pump 7 extends into the interior of the water storage tank 901. The several cooling mechanisms are arranged in sequence from top to bottom. The water pump 7 pumps the warm water in the general heat exchange station 4 of the heating company into the interior of the water storage tank 901, enabling the warm water to be uniformly collected and cooled inside the water storage tank 901. When the height of the warm water stored inside the water storage tank 901 exceeds the height of the drainage block 904, the warm water in the water storage tank 901 is quickly discharged into the buffer tank 801 through the drainage block 904. The buffer tank 801 then transports the warm water to the several cooling mechanisms for secondary cooling, turning the warm water into cold water. The kinetic energy generated when the cold water descends drives the water guiding mechanism to drive the stirring mechanism to rotate, enabling the stirring mechanism to agitate the warm water inside the water storage tank 901, accelerating the release of heat energy from the warm water inside the water storage tank 901. At the same time, the cold water flows into the water storage pool after passing through the stirring mechanism.

[0021] A top rod 903 is fixed to the top of the drainage block 904. On the top of the top rod 903, there is a top cover 902 for supporting the water pump 7. Inside the drainage block 904, there is also a drainage channel 906 for discharging the warm water inside the water storage tank 901. The bottom of the drainage channel 906 penetrates through the water storage tank 901 and extends into the interior of the buffer tank 801. On the water storage tank 901, there is also an altimeter 905 for observing the height of the warm water inside the water storage tank 901. The top cover 902 is set in the shape of a flat-topped cone, and a cavity is formed by the inward depression of the bottom of the top cover 902. The diameter of the bottom of the top cover 902 is larger than the diameter of the water storage tank 901, enabling the top cover 902 to be sleeved above the water storage tank 901. After the water pump 7 transports the warm water into the interior of the water storage tank 901, the warm water inside the water storage tank 901 enters the interior of the drainage channel 906. When the height of the warm water inside the water storage tank 901 exceeds the drainage block 904, due to atmospheric pressure, the warm water inside the water storage tank 901 is quickly discharged into the buffer tank 801 through the drainage channel 906.

[0022] By adopting the above technical solutions: During use, when the cold return water in the main heat exchange station 4 of the heating company needs to flow back to the plant heat exchange station 3, the cold return water in the main heat exchange station 4 of the heating company is pumped into the interior of the water storage tank 901 by the water pump 7, so that the warm water in the cold return water is stored inside the water storage tank 901. A part of the warm water inside the water storage tank 901 will enter the interior of the drainage channel 906, so that the warm water is cooled inside the water storage tank 901. As the warm water stored inside the water storage tank 901 increases, the water level line inside the drainage channel 906 will increase accordingly. When the height of the warm water stored inside the water storage tank 901 exceeds the drainage block 904, the warm water inside the drainage channel 906 will flow to the other end of the drainage channel 906 and then be discharged. The warm water inside the water storage tank 901 will be discharged from the drainage channel 906 through atmospheric pressure, so that the warm water is intermittently discharged and cooled through the drainage channel 906, and the time for cooling the cold return water can be shortened.

[0023] Secondly, referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown in

[0024] The clamping mechanism includes a locking plate 814 and a positioning plate 817 fixed on the outer wall of the heat dissipation cylinder 802. A rotating shaft is provided at one end of the positioning plate 817 away from the heat dissipation cylinder 802. A turning plate 815 is arranged on the rotating shaft. A counterweight 816 is fixed on the top of the turning plate 815, and a secondary protrusion 819 is arranged at the bottom of the turning plate 815. A main protrusion 818 adapted to the positioning plate 817 is arranged on the top of the locking plate 814, and the turning plate 815 is arranged above the locking plate 814. The center of gravity of the turning plate 815 can be changed through the counterweight 816, so that the counterweight 816 drives the turning plate 815 to rotate downward around the rotating shaft. By pushing one of the heat dissipation cylinders 802 upward, one of the heat dissipation cylinders 802 drives the cooperation of one of the main protrusions 818 and the other secondary protrusion 819 to limit one of the main protrusions 818, so that the two heat dissipation cylinders 802 are spliced.

[0025] A filter ring 808 for blocking the heat dissipation holes 820 is further arranged inside the heat dissipation cylinder 802. Two clamping blocks 809 are symmetrically fixed on the outer wall of the filter ring 808. A clamping groove matched with the clamping block 809 is formed on the heat dissipation cylinder 802. The heat dissipation holes 820 can be blocked through the filter ring 808 to prevent foreign objects outside from entering the heat dissipation cylinder 802 through the heat dissipation holes 820 and polluting the inside of the heat dissipation cylinder 802. And the filter ring 808 can be quickly disassembled and assembled through the cooperation of the clamping block 809 and the clamping groove.

[0026] By adopting the above technical solutions: During use, when the cold return water inside the drainage channel 906 is discharged, the cold return water enters the buffer tank 801, and the cold return water is discharged into the buffer tank 801 and conveyed to the heat dissipation cylinder 802 in a swirling manner, so that the cold return water in the buffer tank 801 quickly enters the heat dissipation cylinder 802. After the heat of the cold return water in the heat dissipation cylinder 802 is discharged to the outside of the heat dissipation cylinder 802 through the heat dissipation holes 820, the cold return water in the heat dissipation cylinder 802 is cooled for the second time, so that the temperature of the cooling water flowing back to the factory heat exchange station 3 can be further reduced.

[0027] Again, refer to Figure 8 and Figure 13As shown in the figure, the water guiding mechanism includes an extension cylinder 803 arranged below the cooling mechanism. A height rod 807 is arranged inside the extension cylinder 803. A turbine rod 804 is fixed in the middle of the height rod 807. A number of spiral blades 806 are fixed on the outer wall of the turbine rod 804. A support rod 805 is arranged between the turbine rod 804 and the water storage tank. The stirring mechanism is installed on the support rod 805. An annular groove facilitating the rotation of the height rod 807 is formed on the inner wall of the extension cylinder 803. Both ends of the height rod 807 extend into the annular groove. One end of the blade 806 away from the turbine rod 804 extends outwards to contact the inner wall of the extension cylinder 803. The kinetic energy generated when the cold water descends drives the spiral blade 806 to drive the turbine rod 804 to rotate, so that the turbine rod 804 drives the support rod 805 to rotate, and the support rod 805 drives the stirring mechanism to rotate. Thus, the kinetic energy generated when the water descends is used to provide power for the water guiding mechanism, which can reduce energy consumption and save energy.

[0028] By adopting the above technical solutions: During use, when the cooling water in the heat dissipation cylinder 802 contacts the blade 806, the kinetic energy generated when the heat dissipation cylinder 802 descends drives the blade 806 to drive the turbine rod 804 to rotate. The rotating blade 806 accelerates the air flow velocity in the extension cylinder 803. It can not only generate negative pressure inside the extension cylinder 803, but also reduce the temperature inside the extension cylinder 803. Thus, it can increase the drainage speed of the extension cylinder 803 and can also reduce the temperature of the cold return water again.

[0029] Finally, referring to Figure 3 and Figure 8 As shown in the figure, the stirring mechanism includes a transmission rod 810 fixed on the support rod 805. One end of the transmission rod 810 away from the support rod 805 is provided with an inclined rod 811. One end of the inclined rod 811 away from the transmission rod 810 extends into the water storage tank 901 and is fixed with a mounting block 812. A stirring blade 813 for stirring the warm water is fixed at the bottom of the mounting block 812. One side of the stirring blade 813 facing the transmission rod 810 contacts the inner wall of the water storage tank 901. The inclined rod 811 is obliquely arranged above the water storage tank 901. The top of the inclined rod 811 extends into the cavity, polluting the warm water inside the water storage tank 901. When the support rod 805 drives the transmission rod 810 to rotate, the transmission rod 810 drives the inclined rod 811 to rotate. The inclined rod 811 drives the stirring blade 813 to rotate through the mounting block 812. The warm water inside the water storage tank 901 is stirred by the stirring blade 813. At the same time, the inner wall of the water storage tank 901 can also be cleaned by the stirring blade 813 to prevent scale from forming on the inner wall of the water storage tank 901.

[0030] By adopting the above technical solutions: During use, when the turbine rod 804 rotates, the turbine rod 804 drives the support rod 805 to rotate, the support rod 805 drives the transmission rod 810 to rotate, the transmission rod 810 drives the inclined rod 811 to rotate, the inclined rod 811 drives the mounting block 812 to rotate, and the mounting block 812 drives the stirring blade 813 to rotate, so that the stirring blade 813 agitates the water stored inside the water storage tank 901, thereby reducing the temperature inside the water storage tank 901 when the water storage tank 901 stores water, improving the heat dissipation efficiency of the water storage tank 901 during water storage, and also cleaning the inner wall of the water storage tank 901 through the stirring blade 813 to prevent scale from forming inside the water storage tank 901.

[0031] The present invention provides a nuclear energy heating system as Figure 14 shown, comprising the following steps: Step 1: The heat generated by the reactor in the nuclear island 1 heats the water in the conventional island 2 into high-temperature and high-pressure steam through a steam generator, and part of the steam in the conventional island 2 is extracted to heat the water in the plant heat exchange station 3; Step 2: The hot water of the plant heat exchanger in the plant heat exchange station 3 exchanges heat with the water in the general heat exchange station 4 of the heating company. Through the cooperation of the regulating valve and the general heat exchanger in the general heat exchange station 4 of the heating company, the cold return water in the community heat exchange station 5 is heated, and the community heat exchanger in the community heat exchange station 5 exchanges heat between the hot water and the water in the heating pipeline in the user area 6; Step 3: After the hot water in the heating pipeline in the user area 6 releases heat energy, its temperature drops to become warm water, and the cold water flows back into the heat exchanger in the community heat exchange station 5 through the pipeline. The heat exchanger in the community heat exchange station 5 exchanges heat energy of the warm water again, so that the warm water in the heat exchanger in the community heat exchange station 5 exchanges heat with the water in the exchanger in the general heat exchange station 4 of the heating company again; Step 4: The warm water inside the exchanger in the general heat exchange station 4 of the heating company is pumped into the water storage device 9 by the water pump 7, and the water storage device 9 uniformly recovers the warm water, preliminarily cools the warm water inside the water storage device 9, and the cooled warm water is secondarily cooled by the cooling device 8 to form cold water, and the cold water flows back into the plant heat exchanger in the plant heat exchange station 3 to complete the heat energy exchange.

[0032] As can be seen from the above, during use, the energy generated by the nuclear reaction in the nuclear island 1 will first heat the high-pressure water in the pressure vessel, and the heated high-pressure water flows into the steam generator. Through the steam generator, the water is heated into high-temperature and high-pressure steam, and part of the steam is extracted to heat the water in the plant heat exchange station 3. After the plant heat exchanger in the plant heat exchange station 3 exchanges heat energy, the hot water of the plant heat exchanger in the plant heat exchange station 3 exchanges heat with the community heat exchanger in the general heat exchange station 4 of the heating company, and the hot water exchanges heat with the water in the user area 6 through the general heat exchanger in the general heat exchange station 4 of the heating company, so that the water in the heating pipeline in the user area 6 is heated up.

[0033] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
