[0073] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0074] like Figure 1 and Figure 2As shown, according to the first aspect of an embodiment of the present application, a detritiation system is proposed, comprising: a detritiation unit 110; an input unit 120, connected to the input end of the detritiation unit 110; a regeneration unit 130, connected to the input end of the detritiation unit 110; an output unit 140, connected to the output end of the detritiation unit 110; an emptying unit 150, connected to the output end of the detritiation unit 110; wherein the detritiation unit 110 comprises a plurality of detritiation components arranged in parallel, each detritiation component comprises a drying tower 111, a first control valve 112 and a second control valve 113, the first control valve 112 is arranged at the input end of the drying tower 111, and the second control valve 113 is arranged at the output end of the drying tower 111.

[0075] The detritium removal system provided in the embodiment of the present application includes a detritium removal unit 110, an input unit 120, a regeneration unit 130, an output unit 140 and an emptying unit 150. In the detritium removal system provided in the embodiment of the present application, during use, helium containing tritiated water can enter the detritium removal unit 110 through the input unit 120, and after the detritium removal unit 110 dries and adsorbs the tritiated water in the helium through the drying tower 111, the helium is discharged into the helium loop through the output unit 140. The detritium removal unit 110 of the detritium removal system provided in the embodiment of the present application includes a plurality of detritium removal components arranged in parallel, and each drying tower 111 can work independently through the arrangement of the first control valve 112 and the second control valve 113, and has the characteristics of high detritium removal efficiency, large gas processing capacity and long continuous operation time. Furthermore, the detritiation system provided in the embodiment of the present application also includes a regeneration unit 130. After the detritiation unit 110 has been detritinated for a period of time, a medium with a higher temperature can be supplied to the detritiation unit 110 through the regeneration unit 130 to heat and regenerate the molecular sieve desiccant in the drying tower 111, and then the medium used for regeneration can be discharged to the outside of the detritiation unit 110 through the emptying unit 150, so that the detritiation system can operate continuously, and the detritiation system has high safety and convenient operation. Further, in addition to being used to discharge the medium that has completed the regeneration of the drying tower 111, the detritiation system can also be emptied of impurity gases in the detritiation system through the emptying unit 150 before the detritiation system is detritized, making the use of the detritiation system more efficient.

[0076] It can be understood that since the detritiation unit 110 includes multiple detritiation components arranged in parallel, and each detritiation component includes a drying tower 111, a first control valve 112 and a second control valve 113, the independent use of each drying tower 111 can be controlled by controlling the first control valve 112 and the second control valve 113 of each detritiation component. By setting up multiple drying towers 111, the continuous operation time of the detritiation system can be increased to meet the process requirements.

[0077] It can be understood that the input end of the detritiation unit 110 is connected to the input unit 120 and the regeneration unit 130. Based on this, during the use of the detritiation system, the input unit 120 can be connected to the process section or equipment that needs to be detritiated in the helium loop of the fuel transient irradiation test system, and the regeneration unit 130 is used to connect the regeneration medium. By remotely controlling the switching of the third control valve 123 and the fourth control valve 133, the detritiated helium or the regeneration medium can be conveniently and quickly connected to the input end of the detritiation unit 110.

[0078] Furthermore, the output end of the detritiation unit 110 is connected to the output unit 140 and the emptying unit 150. The output unit 140 is connected to the helium loop process section or equipment of the fuel transient irradiation test system that needs to discharge the detritiated helium. The independent setting of the emptying unit 150 can empty or evacuate the detritiation system when necessary, making the use of the detritiation system more efficient and convenient.

[0079] In some examples, the design pressure of the detritus removal system is 7 MPa, the design temperature is 300°C, and the rated flow rate is 0.04 Nm 3 / min, the main material is 022Cr17Ni12Mo2 stainless steel. The detritium system adopts modular design and layout, the system is skid-mounted, all equipment is installed in an integral frame, and connected to the fuel transient irradiation test system through the nozzle.

[0080] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the input unit 120 includes: an input pipeline 121, connected to the input end of the detritus removal unit 110; a pre-filter 122, arranged on the input pipeline 121; a third control valve 123, arranged at the input end of the input pipeline 121; and a first pressure detection component 124, connected to the input pipeline 121.

[0081] In this technical solution, the structural composition of the input unit 120 is further provided. The input unit 120 may include an input pipeline 121, a pre-filter 122, a third control valve 123 and a first pressure detection component 124. During the detritiation process, the third control valve 123 may be opened to put the input pipeline 121 in a conducting state, and the helium containing tritiated water may enter the detritiation unit 110 after passing through the pre-filter 122. After the detritiation unit 110 dries and adsorbs the tritiated water in the helium through the drying tower 111, the helium is discharged into the helium circuit through the output unit 140. Through the setting of the pre-filter 122, solid and liquid particles in the helium can be filtered out, and then the helium enters the detritiation unit 110, which can make the operation of the detritiation unit 110 safer and more efficient, and at the same time can make the quality of the helium output by the output unit 140 higher.

[0082] It can be understood that, by providing the first pressure detection member 124 , the pressure of the medium input through the input pipeline 121 can be detected, which can make the use of the detritus removal system safer.

[0083] It can be understood that the filtration grade of the pre-filter 122 is 1 μm, that is, the pre-filter 122 is used to remove solid and liquid particles of μm level and above.

[0084] It can be understood that, in addition to being used to input helium that needs to be detritiated, the input pipeline 121 can also be used to input a medium for testing the detritiation system. For example, if the dew point of the test medium is known, the medium with a known dew point is then input into the detritiation unit 110 through the input pipeline 121, and then the dew point of the medium output through the output unit 140 is detected. The detritiation effect of the detritiation unit 110 can be determined, ensuring that the detritiation unit 110 can perform detritiation, thereby ensuring the reliability of the operation of the detritiation system.

[0085] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the regeneration unit 130 includes: a regeneration pipeline 131, connected to the input end of the detritus unit 110; a heater 132, arranged on the regeneration pipeline 131; a fourth control valve 133, arranged at the input end of the regeneration pipeline 131; a first temperature sensor 134, connected to the heater 132; a second temperature sensor 135, connected to the regeneration pipeline 131, and located at the output end of the heater 132.

[0086] In the technical solution, the structural composition of the regeneration unit 130 is further provided. The regeneration unit 130 may include a regeneration pipeline 131, a heater 132, a fourth control valve 133, a first temperature sensor 134 and a second temperature sensor 135. Based on this, during the use of the regeneration unit 130, the regeneration medium can be input into the detritus removal unit 110 through the regeneration pipeline 131. During the regeneration process, the heater 132 can be turned on. The heater 132 can heat the regeneration medium. The heated medium enters the drying tower 111 and is in contact with the drying tower 111. By contacting the molecular sieve desiccant in 11, the molecular sieve desiccant can be heated, carrying the water vapor on the molecular sieve desiccant, and then discharged to the detritus removal system through the emptying unit 150, which can improve the regeneration efficiency of the drying tower 111. The fourth control valve 133 is arranged to facilitate the control of the opening and closing of the regeneration pipeline 131. The first temperature sensor 134 is arranged to facilitate the monitoring of the operating temperature of the heater 132. The second temperature sensor 135 is arranged to facilitate the monitoring of the temperature of the heated medium, thereby ensuring the feasibility of regeneration.

[0087] In some examples, the adsorbent in the drying tower 111 is a spherical molecular sieve with a diameter of φ3 mm to φ5 mm, and the filter elements in the pre-filter 122 and the post-filter 142 are both made of 06Cr19Ni10 sintered stainless steel material.

[0088] In some examples, in order to ensure the reliability of heating, the heater 132 can be an electric heater, a heating resistance wire is arranged in the inner cavity of the electric heater, the heating power of the electric heater is 1 kW, and the electric heating wire is a Ni20Cr80 heating resistance wire.

[0089] like Figure 1 and Figure 2 As shown, in a feasible embodiment, it also includes an experimental simulation unit 160, and the experimental simulation unit 160 includes a regeneration medium supply component 161, a detrition simulation experimental component 162, an adjustment pipeline 163 and an output path 164. The regeneration medium supply component 161 and the detrition simulation experimental component 162 are connected in parallel, the adjustment pipeline 163 and the output path 164 are connected in parallel, the adjustment pipeline 163 is connected to the regeneration medium supply component 161 and the detrition simulation experimental component 162, and the output path 164 is connected to the regeneration medium supply component 161 and the detrition simulation experimental component 162.

[0090] In this technical solution, the structural composition of an experimental simulation unit 160 is further provided. In addition to being used for heating the regenerated medium, the experimental simulation unit 160 can also store the regenerated medium to output the regenerated medium, and can also be used to store the medium for actual measurement and simulation of the detritiation system. Through the setting of the experimental simulation unit 160, the actual detritiation effect of the detritiation unit 110 can be tested, and the regeneration performance can also be tested.

[0091] In this technical solution, the experimental simulation unit 160 includes a regeneration medium supply component 161. Based on this, when the drying tower 111 in the detritiation unit 110 is regenerated by the regeneration unit 130, the regeneration medium supply component 161 can be opened to output the regeneration medium. The regeneration medium adjusts the output flow of the regeneration medium through the adjustment pipeline 163, and then the regeneration medium can be output to the regeneration pipeline 131 of the regeneration unit 130 through the output path 164, and then supplied to the drying tower 111 after being further heated by the heater 132, so as to heat and regenerate the molecular sieve desiccant in the drying tower 111, so that the detritiation system can operate efficiently.

[0092] In this technical solution, the experimental simulation unit 160 also includes a detritiation simulation experimental component 162. Based on this, helium can be stored in the detritiation simulation experimental component 162. When the performance of the detritiation system is then tested, the detritiation simulation experimental component 162 can output a test medium whose dew point value is greater than or equal to a first threshold value. The test medium can be input into the detritiation unit 110 through the input unit 120. After that, it is only necessary to detect the dew point of the medium output through the output unit 140 to determine the detritiation effect of the detritiation unit 110. Based on the same principle, after the drying tower 111 is regenerated through the regeneration medium supply component 161 and the heater 132, the detritus removal simulation experiment component 162 can also output a test medium with a dew point value greater than or equal to the first threshold value. The test medium can be input into the detritus removal unit 110 through the input unit 120. After that, it is only necessary to detect the dew point of the medium output through the output unit 140 to determine the regeneration effect of the detritus removal unit 110 drying tower 111, which is convenient for clarifying the temperature and supply flow rate of the regeneration medium, making the use of the detritus removal system safer and more efficient.

[0093] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the regeneration medium supply component 161 includes: a supply pipeline 1611, a first gas cylinder 1612, a fifth control valve 1613, and a first flow meter 1614. The supply pipeline 1611 is connected to the first gas cylinder 1612, the fifth control valve 1613 and the first flow meter 1614 are arranged on the supply pipeline 1611, and the regulating pipeline 163 and the output pipeline 164 are connected to the supply pipeline 1611.

[0094] In this technical solution, a structural composition of a regeneration medium supply component 161 is further provided. The first gas cylinder 1612 can be used to store the regeneration medium. The setting of the fifth control valve 1613 facilitates the control of the output, closing and opening of the first gas cylinder 1612. The setting of the first flow meter 1614 facilitates the detection of the medium output from the supply pipeline 1611. Based on this, when the detritiation unit 110 is regenerated through the regeneration medium supply assembly 161, the fifth control valve 1613 can be opened, the first gas cylinder 1612 outputs the regeneration medium, and the supply pipeline 1611 is connected to the regulating pipeline 163. In this case, the opening of the fifth control valve 1613 can be adjusted, and the degree of the first flow meter 1614 can be observed. When the flow rate of the regeneration medium supply meets the expected requirements, the regulating pipeline 163 can be closed, and the supply pipeline 1611 is connected to the output pipeline 164. The output pipeline 164 can output the regeneration medium of the target flow rate to the regeneration pipeline 131. After the regeneration medium is heated by the heater 132, the molecular sieve desiccant in the drying tower 111 can be regenerated.

[0095] In some examples, in order to reduce costs and ensure the reliability of the detritus removal system, the medium stored in the first gas cylinder 1612 may be nitrogen.

[0096] In some examples, in order to facilitate the detection of the dew point and pressure of the medium output through the detritus removal simulation experiment component 162 and the medium output through the regeneration medium supply component 161, a second dew point meter 166, a regeneration test instrument valve 167 and a fourth pressure detection component 168 can also be arranged on the output line 164.

[0097] In a feasible embodiment, the tritium removal simulation experiment component 162 includes: a simulation pipeline 1621, a second gas cylinder 1622, a humidifier 1623, a gas-water separator 1624 and a sixth control valve 1625, the simulation pipeline 1621 is connected to the second gas cylinder 1622, the humidifier 1623, the gas-water separator 1624 and the sixth control valve 1625 are sequentially arranged on the simulation pipeline 1621, and the regulating pipeline 163 and the output line 164 are connected to the simulation pipeline 1621.

[0098] In this technical solution, the structural composition of the detritiation simulation experiment component 162 is further provided. When the performance of the detritiation system needs to be tested, the sixth control valve 1625 can be opened, and then the second gas cylinder 1622 outputs the test medium, and the humidifier 1623 and the gas-water separator 1624 are turned on at the same time. In this case, the test medium can be output through the adjustment pipeline 163. In this process, the dew point temperature of the test medium can be adjusted by adjusting the humidifier 1623 and the gas-water separator 1624. When the dew point temperature meets the test requirements, the adjustment pipeline 163 can be closed, so that the test medium is output to the input unit 120 via the output path 164, and the test medium can enter the detritiation unit 110. Thereafter, the dew point of the test medium output via the detritiation unit 110 is detected to test the actual detritiation effect of the detritiation unit 110.

[0099] It can be understood that, based on the same principle, when it is necessary to test the regeneration effect of the detritiation unit 110, after completing the regeneration of the detritiation unit 110, the sixth control valve 1625 can be opened, and then the second gas cylinder 1622 outputs the test medium, and the humidifier 1623 and the gas-water separator 1624 are turned on at the same time. In this case, the test medium can be output through the adjustment pipeline 163. In this process, the dew point temperature of the test medium can be adjusted by adjusting the humidifier 1623 and the gas-water separator 1624. When the dew point temperature meets the test requirements, the adjustment pipeline 163 can be closed, so that the test medium is output to the input unit 120 via the output path 164, and the test medium can enter the detritiation unit 110. Thereafter, the dew point of the test medium output through the detritiation unit 110 is detected to test the actual regeneration effect of the detritiation unit 110.

[0100] In a feasible implementation, a seventh control valve 165 is provided on the regulating pipeline 163. Such a configuration facilitates the control of the opening and closing of the regulating pipeline 163. When adjusting the dew point of the test medium or the flow rate of the regeneration medium, the seventh control valve 165 can be in an open state. After the test medium or the regeneration medium is debugged, the seventh control valve 165 can be closed to allow the test medium or the regeneration medium to be output through the output path 164.

[0101] like Figure 1 and Figure 2 As shown, in a feasible implementation, the output path 164 includes a first output port 1641 and a second output port 1642, the first output port 1641 is used to connect to the input unit 120, and the second output port 1642 is used to connect to the regeneration unit 130. Based on this, it is convenient to connect the output path 164 with the input unit 120 and the regeneration unit 130, so that different medium gases can be supplied to the expected units, which can make the use of the detritus removal system more convenient, avoid frequent switching of the connection mode of the pipeline, and reduce the probability of erroneous operation.

[0102] like Figure 1 and Figure 2 As shown, in a feasible implementation, the output unit 140 includes: an output pipeline 141, connected to the output end of the detritiation unit 110; a post-filter 142, arranged on the output pipeline 141; an eighth control valve 143, arranged at the output end of the output pipeline 141; a third pressure detection member 144, connected to the output pipeline 141; a first dew point meter 145, connected to the output pipeline 141; and an eleventh control valve 146, arranged between the first dew point meter 145 and the output pipeline 141. Based on this, after the detritiation unit 110 is used to detritate the helium containing tritiated water, the post-filter 142 can be used to further filter out solid and liquid particles, and then input into the helium circuit to complete the detritiation of the helium containing tritiated water. The eighth control valve 143 is used to facilitate the control of the opening and closing of the output pipeline 141.

[0103] In this technical solution, in addition to outputting detritiated helium during actual operation, the output unit 140 can also be used to output a medium for testing the detritiation system. By opening the eleventh control valve 146, the detritiated test medium can be tested through the first dew point meter 145, and then the actual detritiation effect and regeneration effect of the detritiation unit 110 can be detected, making the use of the detritiation system safer and more efficient.

[0104] In some examples, in order to improve filtering efficiency, the interior of the pre-filter 122 and the post-filter 142 are filled with sintered 304 stainless steel material.

[0105] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the emptying unit 150 includes: an emptying pipeline 151, connected to the output end of the detritus unit 110; a vacuum pipeline 152, connected to the output end of the emptying pipeline 151; a ninth control valve 153, arranged on the vacuum pipeline 152; an emptying pipe 154, connected to the output end of the emptying pipe 151; a muffler 155, arranged on the emptying pipe 154; a third temperature sensor 156, connected to the emptying pipeline 151; and a tenth control valve 157, arranged on the emptying pipe 154.

[0106] In this technical solution, the structural composition of the emptying unit 150 is further provided. The emptying unit 150 may include an emptying pipeline 151, a vacuum pipeline 152, and a ninth control valve 153. Based on this, the vacuum pipeline 152 can be connected through a vacuum device, and then the ninth control valve 153 is opened. The detritiation unit 110 can be evacuated through the emptying pipeline 151, so that the detritiation system enters a state ready for use.

[0107] In this technical solution, the exhaust unit 150 may also include an exhaust pipe 154 and a muffler 155. Based on this, when the detritiation system is emptied, the gas medium can be discharged to the outside of the detritiation system through the exhaust pipe 154 and the muffler 155, which can reduce the exhaust noise and make it safer to use.

[0108] In some examples, in order to facilitate the control of the exhaust line 151 , the tenth control valve 157 may be disposed at the front end of the muffler 155 .

[0109] like Figure 3 As shown, according to the second aspect of the embodiment of the present application, a detritium removal method is proposed, which is applied to a detritium removal system as in any of the above technical solutions. The detritium removal method includes:

[0110] Step 301: vacuuming the detritus removal unit through an evacuation unit;

[0111] Step 302: inputting the medium containing tritiated water into a detritiation unit, and discharging the medium through an output unit after detritiation treatment;

[0112] Step 303: closing the input unit and the output unit, and emptying the detritus removal unit through the emptying unit;

[0113] Step 304: Start the regeneration unit to regenerate the detritus removal unit.

[0114] The detritiation method provided in the embodiment of the present application is applied to a detritiation system as in any of the above-mentioned technical solutions, so the detritiation method has all the beneficial effects of the detritiation system of the above-mentioned technical solutions.

[0115] like Figures 1 to 3 As shown, through the detritium removal method provided by the embodiment of the present application, the detritium removal unit 110 is first evacuated through the emptying unit 150, so that the detritium removal system enters a standby state, and then when detritium removal is required, the helium containing tritiated water can enter the detritium removal unit 110 through the input unit 120, and after the detritium removal unit 110 dries and adsorbs the tritiated water in the helium through the drying tower 111, the helium is discharged into the helium circuit through the output unit 140. After the detritium removal operation is completed, the system is depressurized, and specifically, the gas in the detritium removal system is emptied through the emptying unit 150. After that, the regeneration medium can be output through the regeneration unit 130, and the regeneration medium is heated at the same time, so that the regeneration medium heats and regenerates the molecular sieve desiccant in the drying tower 111, and then the medium used for regeneration can be discharged to the outside of the detritium removal unit 110 through the emptying unit 150, so that the detritium removal system can operate continuously, so that the detritium removal system is highly safe and easy to operate.

[0116] like Figure 1 and Figure 2 As shown, the detritium removal method provided in the embodiment of the present application, combined with the specific structure of the detritium removal system, may include the following steps:

[0117] The system is connected to connect the detritiation system to the fuel transient irradiation test circuit, wherein the input unit 120 and the output unit 140 are connected to the helium pipeline system of the test circuit, the exhaust pipe 154 of the exhaust unit 150 is connected to the exhaust system of the test circuit, and the vacuum pipeline 152 of the exhaust unit 150 is connected to the vacuum system of the test circuit.

[0118] The system is evacuated, and the detritiation system is evacuated using the fuel transient irradiation test circuit evacuation system and the evacuation pipeline 152. After the vacuum degree of the detritiation system meets the requirements, the ninth control valve 153 is closed, and the detritiation system is in a standby state.

[0119] The system removes tritium, opens the third control valve 123, and the helium containing tritiated water enters the drying tower 111 of the detritiated unit 110 from the input unit 120. After drying and adsorbing the tritiated water, it is discharged into the test loop helium pipeline system through the post-filter 142 and the eighth control valve 143 in sequence.

[0120] The system is depressurized, the third control valve 123 and the eighth control valve 143 are closed, the tenth control valve 157 and the second control valve 113 at the outlet of the detritus removal component are opened in sequence, and the helium in the detritus removal unit 110 is discharged to the exhaust system of the irradiation test circuit through the exhaust pipe 154.

[0121] The system is regenerated. The heater 132 and the fourth control valve 133 are turned on. The dry nitrogen is electrically heated and enters the drying tower 111 of the detritus removal unit 110 to heat and regenerate the molecular sieve desiccant. The regenerated gas coming out of the drying tower 111 is silenced by the exhaust port muffler 155 and then discharged into the exhaust system of the irradiation test circuit.

[0122] Therefore, the embodiment of the present invention aims at the detritium removal requirements of the transient irradiation test system in the nuclear fuel pile, realizes the removal of tritium from the helium loop, which is the core component of the test system, ensures the purity of the helium in the irradiation test loop, and prevents the release of radioactive tritium into the environment. The present invention adopts a molecular sieve drying and adsorption process to remove tritiated water in the helium loop. The detritium removal system is provided with 6 groups of parallel detritium removal components, each group of detritium removal components can be operated independently in sequence, and a pre-filter 122 and a post-filter 142 are respectively provided at the inlet and outlet of the detritium removal unit 110, which has the characteristics of high detritium removal efficiency, large gas processing capacity and long continuous operation time. In addition, the present invention adopts an inert gas electric heating method to regenerate the molecular sieve desiccant, and the detritium removal waste gas is discharged to the waste gas treatment system, and the detritium removal and regeneration are performed through a computer remote operation system. The detritium removal system adopts a modular design and layout, and has the characteristics of high safety, convenient installation and operation, etc.

[0123] like Figure 1 and Figure 2 As shown, in a feasible implementation, the detritiation method further includes: in response to a leak detection instruction, supplying an experimental medium to the detritiation system through the experimental simulation unit 160, and controlling the output end of the detritiation system to be in a closed state to perform leak detection.

[0124] In this technical solution, considering the safe operation of the detritiation system, the leakage points of the detritiation system can also be detected. Based on this, the experimental medium can be supplied to the detritiation unit 110, and the detritiation system can be kept at a certain pressure. After that, the output end of the detritiation unit 110 is controlled to be in a closed state, and the leakage points of the detritiation system can be detected, thereby ensuring the safe operation of the equipment.

[0125] like Figure 1 and Figure 2 As shown, in some examples, in combination with the specific structure of the detritium removal system, in response to the leak detection instruction, the specific control of the detritium removal system may include the following steps:

[0126] Open the fifth control valve 1613 of the experimental simulation unit 160, the instrument valve before the fourth pressure detection member 168 and the first output port 1641, and close the second output port 1642 and the twelfth control valve 1626 of the experimental simulation unit 160;

[0127] Open the third control valve 123, the first control valve 112 and the second control valve 113 of the detritiation system, close the eighth control valve 143, the tenth control valve 157 and the fourth control valve 133 of the detritiation system, first slowly increase the pressure of the detritiation system to 3.5MPa, and then increase the pressure by 0.5MPa in steps until it reaches the test pressure and then maintain the pressure for 30 minutes. Preferably, the test pressure is 7MPa. During the pressure maintenance period, apply a leak detection agent to the welds and mechanical connections for inspection. After the test, reduce the pressure of the detritiation system to atmospheric pressure. Specifically, the test is qualified if there are no bubbles, abnormal sounds, or visible deformations in the welds and mechanical connections during the test.

[0128] In a feasible embodiment, the detritiation method further includes: in response to a test instruction, supplying a test medium having a dew point temperature greater than or equal to a first threshold to the detritiation unit 110 through the experimental simulation unit 160 to test the dew point value of the medium discharged through the output end of the detritiation unit 110.

[0129] In this technical solution, considering the need to accurately understand the detritiation capability of the detritiation system, it is also possible to respond to a test instruction, and then supply a test medium with a known dew point to the detritiation unit 110, and then detect the dew point value of the medium output by the detritiation unit 110, so that the detritiation effect of the detritiation system can be known, making the use of the equipment more reliable.

[0135] In this technical solution, considering that the detritiation unit 110 can be regenerated by the setting of the regeneration unit 130, the detritiation effect after the detritiation system is regenerated should be verified. Based on this, the detritiation system can also respond to the regeneration experiment instruction. The regeneration medium can be first supplied to the detritiation unit 110 through the regeneration medium supply component 161 of the experimental simulation unit 160, and the heater 132 heats the regeneration medium to regenerate the drying tower 111. After the regeneration is completed, the detritiation simulation experiment component 162 can output a test medium with a dew point temperature greater than or equal to the first threshold to the detritiation unit 110, and then the dew point value of the medium output through the detritiation unit 110 is detected, so that the regeneration effect of the detritiation system can be known, making the use of the equipment safer and more reliable.

The detritiation system is evacuated to remove the regeneration medium, and then the six groups of drying towers 111 of the detritiation unit 110 are subjected to adsorption tests in turn. The test time of each group of drying towers 111 is 4 hours. After the adsorption test of each group of drying towers 111 is completed, the helium dew point at the outlet of the drying tower 111 measured by the first dew point meter 145 of the output unit 140 is recorded. Preferably, the helium dew point measured by the first dew point meter 145 at the outlet is ≤-40°C, which means the regeneration test is qualified.

[0140] In a feasible embodiment, in response to the regeneration instruction, the step of supplying the regeneration medium to the detritiation unit 110 through the regeneration unit 130 includes: turning on the heater 132 of the regeneration unit 130, supplying the regeneration medium to the detritiation unit 110 through the regeneration pipeline 131, the regeneration medium heating and regenerating the molecular sieve desiccant in the drying tower 111, and then discharging the gas through the exhaust unit 150.
