[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0025] In order to solve the problem of reducing pollutant emissions while providing heating and cooling services to users, the present application provides a nuclear energy combined heating and cooling system, which can provide heating and cooling services to users based on a nuclear reactor.
[0026] Figure 1 This is a schematic diagram of a nuclear energy combined cooling and heating system according to an embodiment of the present application.
[0027] like Figure 1As shown, the nuclear energy combined cooling and heating system provided in this application includes a nuclear reactor 100, an integrated heat exchange device 400, a cooling user side 200, and a heating user side 300. The integrated heat exchange device is connected to the nuclear reactor through corresponding pipelines, and generates a high-temperature medium and a low-temperature medium based on the heat and work generated by the nuclear reactor.
[0028] The integrated heat exchange device is also connected to the cooling user side and the heating user side through corresponding pipelines, and is used to output high-temperature medium to the heating user side so that the heating user side provides heating services to the user based on the high-temperature medium; it is also used to output low-temperature medium to the cooling user side so that the cooling user side provides cooling or cooling services to the user based on the low-temperature medium.
[0029] The high temperature of the high-temperature medium and the low temperature of the low-temperature medium in this application refer to concepts relative to normal temperature. For example, in the winter in North China, normal temperature refers to 0 to -30°C, so the high-temperature medium here refers to a high-temperature liquid with a temperature higher than the normal temperature, such as high-pressure hot water; for the summer in North China, normal temperature refers to 10 to 40°C, so the low-temperature medium here refers to a low-temperature liquid with a temperature lower than the normal temperature, such as low-temperature liquid cold water.
[0030] The nuclear reactor in this application is a swimming pool-type low-temperature heating reactor or a shell-type low-temperature heating reactor. The swimming pool-type low-temperature heating reactor is a nuclear reactor used for urban centralized heating, which realizes safe, efficient and low-carbon heating through the design of a normal-pressure water pool. The core of the swimming pool-type low-temperature heating reactor is placed at the bottom of a deep water pool at normal pressure. The static pressure of the water layer is used to increase the outlet water temperature (about 90°C), and the heat is transferred to the heating circuit through multi-stage heat exchange. The cooling water has the functions of a moderator, a reflector and a protective layer, and is combined with heavy concrete shielding to ensure radiation safety.
[0031] The shell-type low-temperature heating reactor (LTHR) is a nuclear reactor that uses a pressure vessel to enclose the reactor core. Its core advantages are its compact design and passive safety features. It typically uses an integrated pressure vessel design, integrating the core, steam generator, and control mechanisms within a single pressure vessel. This significantly reduces the risk of coolant leaks and improves system reliability. This type of reactor eliminates the main circulation pump and instead relies on coolant density differences to automatically circulate the core coolant, fundamentally eliminating the risk of power outages.
[0032] When a swimming pool type low temperature heating reactor 101 is selected, the integrated heat exchange device includes a primary circuit outlet pipe 103 connected to the swimming pool type low temperature heating reactor, a primary circuit pump 102 arranged on the primary circuit outlet pipe, a primary heat exchanger 104 connected to the primary circuit outlet pipe, a primary circuit inlet pipe 105 connected between the swimming pool type low temperature heating reactor 101 and the primary heat exchanger, a secondary heat exchanger inlet pipe 108 having one end connected to the primary heat exchanger, a secondary heat exchanger 110 connected to the other end of the secondary heat exchanger inlet pipe, a secondary heat exchanger outlet pipe 107 having one end connected to the primary heat exchanger, an absorption heat pump unit 109 connected to the other end of the secondary heat exchanger outlet pipe, a secondary circuit pump 106 arranged on the secondary heat exchanger outlet pipe, a water supply device 111 connected to the water inlet of the absorption heat pump unit, and a pressurized water pump 112 arranged on the pipeline for connecting the absorption heat pump unit and the water supply device. Figure 2 The water supply device is a common fresh water tank or a seawater desalination and desalination device.
[0033] The hot water generated by the swimming pool-type low-temperature heating reactor 101 is pumped by the primary-circuit pump 102 through the primary-circuit outlet pipe 103 to the hot-side inlet of the primary heat exchanger 104. The hot-side outlet water of the primary heat exchanger 104 is returned to the swimming pool-type low-temperature heating reactor 101 via the primary-circuit inlet pipe 105, completing the primary-circuit circulation process. The cold-side outlet water of the primary heat exchanger 104 is respectively delivered to the hot-side inlet of the secondary heat exchanger 110 and the high-temperature heat source inlet of the absorption heat pump unit 109 via the secondary heat exchanger inlet pipe 108. The hot-side outlet water of the secondary heat exchanger 110 and the high-temperature heat source outlet water of the absorption heat pump unit 109 are then combined and then delivered by the secondary-circuit pump 106 through the secondary heat exchanger outlet pipe 107 to the cold-side inlet of the primary heat exchanger 104, completing the secondary-circuit circulation process.
[0034] When a shell-type low-temperature heating reactor 113 is selected, given that a primary heat exchanger 104 is provided in the containment vessel of this type of reactor, the integrated heat exchange device includes a secondary heat exchanger water inlet pipe 108 connected to the primary heat exchanger at one end, a secondary heat exchanger 110 connected to the other end of the secondary heat exchanger water inlet pipe, a secondary heat exchanger water outlet pipe 107 connected to the primary heat exchanger at one end, an absorption heat pump unit 109 connected to the other end of the secondary heat exchanger water outlet pipe, a secondary circuit pump 106 provided on the secondary heat exchanger water outlet pipe, a water supply device 111 connected to the water inlet of the absorption heat pump unit, and a pressurized water pump 112 provided on a pipeline connecting the absorption heat pump unit and the water supply device, as shown in FIG. Figure 3 The water supply device is a common fresh water tank or a seawater desalination and desalination device.
[0035] The core and primary cooling system of the shell-and-shell low-temperature heating reactor 113 are integrated within a sealed containment vessel, preventing the leakage of radioactive materials and reducing the need for external piping. The primary cooling system of the shell-and-shell low-temperature heating reactor 113 transfers heat to the secondary cooling system via the primary heat exchanger 104. The cold-side outlet water of the primary heat exchanger 104 is fed via the secondary heat exchanger inlet pipe 108 to the hot-side inlet of the secondary heat exchanger 110 and the high-temperature heat source inlet of the absorption heat pump unit 109. The hot-side outlet water of the secondary heat exchanger 110 and the high-temperature heat source outlet water of the absorption heat pump unit 109 are then combined and pumped by the secondary cooling system pump 106 through the secondary heat exchanger outlet pipe 107 to the cold-side inlet of the primary heat exchanger 104, completing the secondary cooling system.
[0036] The heating user side of this application includes a water-heat co-transmission pipe 301, one end of which is connected to a comprehensive heat exchange device. This pipe is used to deliver high-temperature hot water to users. These users include, but are not limited to, urban heat users 302, as well as a city reservoir 304 connected via an underground pipe 303 for heat storage. The underground pipe 303 is used to store heat, and the city reservoir 304 is used to supply fresh water to urban residents. The pipe used to supply heat to the urban heat users is equipped with a heat-use regulating valve 305, and the pipe connected to the underground pipe is equipped with a heat-storage regulating valve 306.
[0037] The cooling user side includes a liquid cooling return pipe 201 and a liquid cooling water supply pipe 202 connected to the integrated heat exchange device, which are used to provide cooling services to users. The user here can be an intelligent computing center 203.
[0038] During the heating season, desalted water from water supply device 111 is pumped by pressurized water pump 112 into absorption heat pump unit 109, where it absorbs heat from both high-temperature and low-temperature heat sources, completing the first heat exchange. The desalted water, after the first heat exchange, enters the cold-side inlet of secondary heat exchanger 110 for the second heat exchange. Hot fresh water at the cold-side outlet of secondary heat exchanger 110 is delivered to heating user 300 via a one-way pipe via water-heat co-transmission pipe 301. The outlet of water-heat co-transmission pipe 301 is connected to a city heating user 302 via a heat regulating valve 305. The heat in the hot fresh water is used by city heating user 302 for district heating. The cooled, ambient-temperature fresh water then flows into city reservoir 304, where it is used as water for urban residents. This process allows for independent regulation of the hot fresh water supply temperature and heating load based on user heat load requirements, such as diurnal temperature differences and seasonal variations.
[0039] The liquid cooling water in the liquid cooling water supply pipe 202 is connected to the water inlet pipe of the intelligent computing center 203, and the water outlet pipe of the intelligent computing center 203 is connected to the liquid cooling water return pipe 201. The liquid cooling water, which has absorbed heat and heated up, is fed through the liquid cooling water return pipe 201 to the low-temperature heat source inlet of the absorption heat pump unit 109. The low-temperature heat source outlet of the absorption heat pump unit 109 is then connected to the liquid cooling water supply pipe 202, completing the three-circuit refrigeration cycle. This process reduces the low-temperature heat of the working medium water in the liquid cooling water return pipe 201 to liquid cooling water, which is then delivered to the intelligent computing center 203 via the liquid cooling water supply pipe 202 for equipment cooling.
[0040] During the non-heating season, desalted water from water supply device 111 is pumped via pressurized water pump 112 into absorption heat pump unit 109, where it absorbs heat from both the high-temperature and low-temperature heat sources, completing the first heat exchange. The desalted water, having undergone the first heat exchange, then enters the cold-side inlet of secondary heat exchanger 110 for a second heat exchange. The hot fresh water at the cold-side outlet of secondary heat exchanger 110 is delivered to heating user side 300 via a one-way pipe via water-heat co-transmission pipe 301. The outlet of water-heat co-transmission pipe 301 is connected to underground pipe 303 via a heat storage regulating valve 306. The heat in the hot fresh water is stored in underground pipe 303, and the cooled, room-temperature fresh water flows into city reservoir 304, where it is used as water for urban residents.
[0041] The liquid cooling water in the liquid cooling water supply pipe 202 is connected to the water inlet pipe of the intelligent computing center 203, and the water outlet pipe of the intelligent computing center 203 is connected to the liquid cooling water return pipe 201. The liquid cooling water, which has absorbed heat and heated up, is fed through the liquid cooling water return pipe 201 to the low-temperature heat source inlet of the absorption heat pump unit 109. The low-temperature heat source outlet of the absorption heat pump unit 109 is then connected to the liquid cooling water supply pipe 202, completing the three-circuit refrigeration cycle. This process reduces the low-temperature heat of the working medium water in the liquid cooling water return pipe 201 to liquid cooling water, which is then delivered to the intelligent computing center 203 via the liquid cooling water supply pipe 202 for equipment cooling.
[0042] As can be seen from the above technical solution, this embodiment provides a nuclear energy combined cooling and heating system, which includes a nuclear reactor, an integrated heat exchange device, a cooling user side, and a heating user side.
