Description

Technical Field

[0001] The present invention relates to the field of combustion control of deuterium-tritium fuel for thermonuclear fusion reactions, and specifically relates to a method and system for capturing combustion products of thermonuclear fusion reactions. Background Art

[0002] With the rapid increase in the global population, the wide-field collaborative development of the economy, and the deep energy demand of humanity, the realization of nuclear fusion energy has become a major scientific issue jointly addressed by humanity. Nuclear fusion energy mainly relies on thermonuclear fusion reactions. The fusion reaction of deuterium (D) and tritium (T) (D + T → He + n + 17.6 MeV) is the focus of current controlled nuclear fusion research. Its combustion efficiency depends on the optimization of the plasma "triple product" (temperature, density, confinement time), but in actual reactions, the problem of incomplete fuel combustion often occurs.

[0003] The main technical challenges for incomplete combustion of deuterium-tritium fuel are fuel mixing and boundary losses. The core problems of fuel mixing are mainly fuel losses at the plasma edge and the edge-localized mode effect; the fuel at the plasma edge directly contacts the divertor due to the open magnetic field lines, resulting in incomplete combustion of deuterium-tritium fuel or even being discharged without participating in the fusion reaction, leading to waste of fuel loss. Therefore, fuel mixing and boundary losses are the key bottlenecks restricting the deuterium-tritium fusion energy gain (Q value). Summary of the Invention

Detailed implementation manners

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] The present invention will be further described below with reference to specific embodiments.

[0048] The present invention provides a method for capturing the combustion products of a thermonuclear reaction, which includes the following steps:

[0049] S1: Cooling the deuterium-tritium combustion products; the purpose of this step is to reduce the Brownian motion of gas molecules such as deuterium, tritium, and helium in the deuterium-tritium combustion products;

[0050] S2: Performing a first photolysis treatment on the cooled deuterium-tritium combustion products; the purpose is to photolyze the unburned tritium molecules or deuterium molecules in the deuterium-tritium combustion products to make them photolyze into tritium atoms or deuterium atoms;

[0051] S3: Performing a first separation treatment on the deuterium-tritium combustion products after the first photolysis treatment; the purpose of this step is to aggregate or confine the tritium atoms or deuterium atoms obtained after the separation photolysis treatment for easy collection;

[0052] S4: Performing a first collection treatment on the first product obtained after the first separation treatment;

[0053] S5: Performing a second photolysis treatment on the remaining combustion products after the first separation treatment; the purpose of this step is to photolyze the deuterium molecules or tritium molecules in the remaining combustion products to make them photolyze into deuterium atoms or tritium atoms;

[0054] S6: Performing a second separation treatment on the remaining combustion products after the second photolysis treatment;

[0055] S7: Performing a collection treatment on the second product obtained after the second separation treatment;

[0056] S8: Performing a collection treatment on the remaining combustion products after the second separation treatment.

[0057] The combustion products of a thermonuclear reaction generally contain unburned tritium molecules, deuterium molecules, and helium gas molecules. In order to solve the technical problem of fuel loss and waste, the present invention adopts a step-by-step recovery method to recover the unburned tritium molecules and deuterium molecules in the combustion products. At the same time, for the convenience of recovery, the present invention adopts a photolysis method to photolyze them into atoms, which improves the recovery purity and saves time costs.

[0058] Specifically, first, the combustion products of thermonuclear fusion reactions (gas molecules such as deuterium, tritium, and helium) are cooled at low temperature to reduce the Brownian motion of gas molecules such as deuterium, tritium, and helium. The first product is separated through the first photolysis, separation, and collection processes; the second product is separated through the second photolysis, separation, and collection processes, and then the remaining gas is collected to achieve the separation and recovery of the combustion products.

[0059] Preferably, the wavelength of the first photolysis process is 2.0 - 5.0 Gauss / cm, and the first product is tritium atoms; the wavelength of the second photolysis process is 0.8 - 1.5 Gauss / cm, and the second product is deuterium atoms;

[0060] Or; the wavelength of the first photolysis process is 0.8 - 1.5 Gauss / cm, and the first product is deuterium atoms; the wavelength of the second photolysis process is 2.0 - 5.0 Gauss / cm, and the second product is tritium atoms.

[0061] Among them, in this embodiment, different wavelengths are used for the photolysis of tritium molecules and deuterium molecules. Tritium molecules can be photolyzed first, or deuterium molecules can be photolyzed first, as long as the separation of the two can be achieved.

[0062] Preferably, before the first photolysis process, the following steps are further included:

[0063] S02: Oscillating the cooled deuterium-tritium combustion products.

[0064] Preferably, before the second photolysis process, the following steps are further included:

[0065] S05: Oscillating the remaining combustion products after the first separation process.

[0066] Preferably, before step S8, the following steps are further included:

[0067] S08: Oscillating the remaining combustion products after the second separation process.

[0068] The purpose of the above oscillating process is to dynamically enhance the Brownian motion of gas molecules such as deuterium, tritium, and helium in the 5 - ultra-low temperature cooling tube.

[0069] Preferably, the first separation process confines the first product in a specific area through the first magnetic field gradient; the second separation process confines the second product in a specific area through the second magnetic field gradient. The first magnetic field gradient matches the first product, and the second magnetic field gradient matches the second product. In this embodiment, deuterium atoms or tritium atoms after photolysis are separated by a magnetic field, and the required equipment is simple and easy to implement.

[0070] Preferably, the first separation process further includes a step of decelerating the first product; the second separation process further includes a step of decelerating the second product. The purpose of the deceleration process is to assist the magnetic field in separation.

[0071] More preferably, when the first product is a tritium atom, the first magnetic field gradient is 2.0 - 5.0 Gauss / cm; when the second product is a deuterium atom, the second magnetic field gradient is 0.8 - 1.5 Gauss / cm;

[0072] Or, when the first product is a deuterium atom, the first magnetic field gradient is 0.8 - 1.5 Gauss / cm; when the second product is a tritium atom, the second magnetic field gradient is 2.0 - 5.0 Gauss / cm.

[0073] In this embodiment, the interaction between the magnetic field gradient and the magnetic moment of tritium atoms or deuterium atoms is utilized to confine the tritium atoms or deuterium atoms in the region of the minimum magnetic field in the magnetic trap, which facilitates collection.

[0074] Preferably, the temperature of the cooling process in step S1 is 10 - 100 μK.

[0075] See Figure 1 , the present invention also provides a system for capturing combustion products of a thermonuclear fusion reaction, which includes a gas source pipe 3, a cooling component, a photolysis component, a separation component, and a collection component. The photolysis component is used to emit a specific wavelength to perform photolysis treatment on the combustion production area in the cooling component; the separation component confines the products after photolysis in a specific area of the cooling component, and the collection component is used to collect the first product, the second product, and the remaining combustion products after separation.

[0076] The combustion products of the thermonuclear fusion reaction enter the cooling component from the gas source pipe 3, are subjected to photolysis treatment by the photolysis component, the atoms after photolysis treatment are confined in a specific area by the separation component, and then are collected by the collection component, thus realizing the collection and recycling of the combustion products of the thermonuclear fusion reaction, and the recycled fuel has a high purity.

[0077] Specifically, see Figure 1 , the gas source pipe 3 is used to transport the combustion products of the thermonuclear fusion reaction to the capture system; the cooling component in this embodiment is an ultra-low temperature cooling pipe 5, and the ultra-low temperature cooling pipe 5 is connected to the gas source pipe 3. The cooling component can be any container capable of realizing ultra-low temperature treatment. In this embodiment, the ultra-low temperature cooling pipe 5 is adopted, and at the same time, a treatment area for accommodating the photolysis component and the separation component is set in the ultra-low temperature cooling pipe 5, with the purpose of making the combustion products of the thermonuclear fusion reaction to be treated flow extremely slowly in the ultra-low temperature cooling pipe, so as to better achieve the separation purpose and improve the separation purity. See Figure 1, an ultra-low temperature cooling tube solenoid valve rod 31 and an ultra-low temperature cooling tube solenoid valve 32 are provided on the ultra-low temperature cooling tube 5 to control the on / off of the ultra-low temperature cooling tube 5.

[0078] In this embodiment, the photolysis component is an ultraviolet laser 10. The ultraviolet laser can emit high-energy photons of different wavelengths as needed to break the chemical bonds of deuterium molecules or deuterium molecules, so that the covalent bonds between their molecules are photolyzed into tritium atoms or deuterium atoms. See Figure 1 , the ultraviolet laser 10 is fixed to the tube wall of the ultra-low temperature cooling tube 5 through an ultraviolet laser fixing bracket 11 and an ultraviolet laser fixing base 12.

[0079] In this embodiment, the separation component is a magnetic trap. A prefabricated high-stable magnetic field gradient is formed through the magnetic trap to interact with the magnetic moments of tritium atoms or deuterium atoms, so that the tritium atoms or deuterium atoms are confined in the region of the minimum magnetic field in the magnetic trap.

[0080] The reaction combustion products enter the ultra-low temperature cooling tube 5 from the gas source tube 3 for ultra-low temperature cooling treatment; the reaction combustion products flow in the ultra-low temperature cooling tube 5 and are photolyzed into tritium atoms or deuterium atoms when passing through the illumination area of the ultraviolet laser 10. The tritium atoms or deuterium atoms are further confined in a specific region (the region of the minimum magnetic field) by the magnetic trap, and the collection component collects the tritium atoms or deuterium atoms. After the tritium atoms or deuterium atoms are collected, only helium molecules remain in the combustion products, and then the collection component collects the helium molecules.

[0081] Furthermore, the photolysis component and the separation component are arranged in the processing area of the cooling component; the specific region is located in the processing area. See Figure 1 , an ultraviolet laser 10 and a magnetic trap are arranged in the area to be processed of the ultra-low temperature cooling tube. That is, the reaction combustion products of the thermonuclear fusion reaction slowly flow in the ultra-low temperature cooling tube and are subjected to photolysis and separation treatment when passing through the processing area.

[0082] Preferably, the separation component includes a magnetic trap, and the magnetic trap can form a predetermined magnetic field gradient. More preferably, see Figure 1 , the separation component includes a first magnetic trap 15 and a second magnetic trap 16. The first magnetic trap 15 and the second magnetic trap 16 can form a prefabricated high-stable magnetic field gradient. The tritium atoms or deuterium atoms obtained after photolysis can be confined in a specific region (the region of the minimum magnetic field) by the magnetic trap.

[0083] More preferably, the separation component further includes a deceleration device. The deceleration device is arranged near the magnetic trap, and the deceleration device is used to decelerate the first product or the second product of the magnetic field formed by the magnetic trap. See Figure 1 , the deceleration device in this embodiment is a Zeeman decelerator 13. The Zeeman decelerator 13 is arranged near the magnetic field formed by the magnetic trap, and the purpose is to assist in separation.

[0084] Preferably, referring to Figure 1 , the collection component includes a first collection device, and the first collection device communicates with the specific area; the first collection device is used for collecting tritium atoms and deuterium atoms.

[0085] Specifically, referring to Figure 1 , the first collection device includes a first vacuum pump 17, a first trapping diversion pipe 20, a shunt pipe 21, a first solenoid valve 22, a second solenoid valve 24, a first trap 23 and a second trap 25. The first vacuum pump 17 is connected to the specific area, and the shunt pipe 21 is communicated with the first vacuum pump 17 through the first trapping diversion pipe 20; both the first trap 23 and the second trap 25 are communicated with the shunt pipe 21; the first solenoid valve 22 is arranged on the first trap 23, and the second solenoid valve 24 is arranged on the second trap 25. After the first separation process is completed, the first vacuum pump 17 communicating with the specific area (magnetic field minimum area) is opened, and the enriched tritium atoms or deuterium atoms are controlled by the first solenoid valve 22 and transferred to the shunt pipe 21 through the first trapping diversion pipe 20 and enter the first trap 23. After the collection is completed, the first solenoid valve 22 is closed; after the second separation process is completed, the first vacuum pump 17 communicating with the specific area (magnetic field minimum area) is opened, and the enriched tritium atoms or deuterium atoms are controlled by the second solenoid valve 24 and transferred to the shunt pipe 21 through the first trapping diversion pipe 20 and enter the second trap 25. After the collection is completed, the second solenoid valve 24 is closed. The present invention sets one photolysis component and one separation component to realize the separation and recovery of tritium atoms or deuterium atoms, and the equipment is simple.

[0086] Further, referring to Figure 1 , the collection component further includes the second collection device. The second collection device includes a second vacuum pump 30, a second trapping diversion pipe 29 and a third trap 28. The second vacuum pump 30 is connected to the cooling component (ultra-low temperature cooling pipe), and the third trap 28 is communicated with the second vacuum pump 30 through the second trapping diversion pipe 29. The second vacuum pump can be connected to other areas of the ultra-low temperature cooling pipe except the treatment area, and the second collection device is used for collecting helium molecules. Specifically, after the collection of tritium atoms or deuterium atoms is completed, the second vacuum pump 30 is opened to pump the helium molecules 7 into the third trap 28 through the second trapping diversion pipe 29 until the collection is completed and the second vacuum pump 30 is closed.

[0087] Preferably, the collection component further includes a first monitoring device and a second monitoring device. The first monitoring device is disposed on the first vacuum pump 17, and the second monitoring device is disposed on the second vacuum pump 30 or near the second vacuum pump 30. The detection device in this embodiment is a spectrometer, specifically including a first spectrometer 18 (a first spectrometer probe 19 is disposed on the first spectrometer 18) and a second spectrometer 26 (a second spectrometer signal processor 27 is disposed on the second spectrometer 26). The first spectrometer is used to monitor whether there are tritium atoms or deuterium atoms in the first vacuum pump 17, and the second spectrometer is used to monitor whether there are helium molecules in the first vacuum pump 30 or the ultra-low temperature cooling pipe 5.

[0089] More preferably, the trapping system further includes an oscillation device, and the oscillation device is disposed on the cooling component. The oscillation device in this embodiment is an adaptive ultrasonic oscillator 2. The adaptive ultrasonic oscillator 2 is used to dynamically enhance the Brownian motion of gas molecules such as deuterium, tritium, and helium in the ultra-low temperature cooling pipe 5. The adaptive ultrasonic oscillator 2 is fixed on the ultra-low temperature cooling pipe 5 through an ultrasonic oscillator fixing support rod 1. The adaptive ultrasonic oscillator 2 can oscillate at any frequency as long as it is turned on.

[0090] Preferably, the operation process of a tritium and deuterium combustion product capture system in a thermonuclear fusion reaction of the present invention is as follows: The gas source pipe 3 injects the thermonuclear fusion reaction combustion products (gas molecules such as tritium, deuterium, and helium) into the cryogenic cooling pipe 5 through the nozzle 4 for cryogenic cooling to reduce the Brownian motion of gas molecules such as tritium, deuterium, and helium. Then, the nozzle 4 is closed, the cryogenic cooling pipe solenoid valve 32 is opened, and the adaptive ultrasonic oscillator 2 is turned on to dynamically enhance the Brownian motion of gas molecules such as tritium, deuterium, and helium in the cryogenic cooling pipe 5. The ultraviolet laser 10 emits high-energy photons 9 with a specific wavelength to irradiate the tritium molecules 8 to break the chemical bonds of the tritium molecules 8, so that the covalent bonds between the molecules are photolyzed into tritium atoms. The Zeeman decelerator 13 then decelerates the tritium atoms to assist the prefabricated high-stable magnetic field gradient formed by the first magnetic trap 15 and the second magnetic trap 16 to interact with the magnetic moment of the tritium atoms, so that the tritium atoms are confined in a specific region (magnetic field minimum region) in the magnetic trap. Then, the first vacuum pump 17 communicating with the magnetic field minimum region is turned on, and the enriched tritium atoms are screened by the first spectrometer 18 and then controlled by the first solenoid valve 22 to be transferred to the shunt pipe 21 through the first capture diversion pipe 20 and enter the first capture device 23 (tritium capture device). After the first spectrometer 18 determines that there are no tritium atoms in the first vacuum pump 17, the first solenoid valve 22 is closed; the ultraviolet laser 10 is adjusted to emit high-energy photons 9 with a specific wavelength to irradiate the deuterium molecules 6 to break the chemical bonds of the deuterium molecules, so that the covalent bonds between the molecules are photolyzed into deuterium atoms. The Zeeman decelerator 13 then decelerates the deuterium atoms to assist the prefabricated high-stable magnetic field gradient formed by the first magnetic trap 15 to interact with the magnetic moment of the deuterium atoms, so that the deuterium atoms are confined in the magnetic field minimum region in the magnetic trap. Then, the first vacuum pump 17 communicating with the magnetic field minimum region is turned on, and the enriched deuterium atoms are screened by the first spectrometer 18 and then controlled by the second solenoid valve 24 to be transferred to the shunt pipe 21 through the first capture diversion pipe 20 and enter the second capture device (deuterium capture device). After the first spectrometer 18 determines that there are no deuterium atoms in the first vacuum pump 17, the second solenoid valve 24 is closed, the ultraviolet laser 10 is turned off, and the first magnetic trap 15 and the second magnetic trap 16 are turned off; when the second spectrometer 26 detects that there are only helium molecules 7 in the cryogenic cooling pipe 5, the adaptive ultrasonic oscillator 2 is adjusted to dynamically enhance the Brownian motion of the helium molecules 7 in the cryogenic cooling pipe 5. The second spectrometer 26 controls the second spectrometer signal processor 27 to turn off the ultraviolet laser 10, the first magnetic trap 15, and the first vacuum pump 17, and turn on the second vacuum pump 30 to draw the helium molecules 7 through the second capture diversion pipe 29 into the third capture device 28 (helium capture device). When the second spectrometer 26 detects that there are no helium molecules 7 in the cryogenic cooling pipe 5, the second vacuum pump 30 is closed.

[0091] The present invention sprays a deuterium-tritium-helium mixed gas through a nozzle. An ultraviolet laser activates the splitting of molecules such as deuterium and tritium into deuterium atoms and tritium atoms at a specific wavelength, and a Zeeman decelerator decelerates the deuterium atoms and tritium atoms respectively. The magnetic trap interacts with the magnetic moments of the deuterium atoms and tritium atoms respectively through the magnetic field gradient, and the deuterium and tritium atoms are successively trapped in the magnetic field minimum region. A vacuum pump sends the deuterium atoms and tritium atoms to different traps in a slightly negative pressure environment. When the trapping of deuterium and tritium atoms is completed, the spectrometer controls the vacuum pump to send helium molecules into the circular trap; to achieve the trapping of the deuterium-tritium-helium mixed gas.
