Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger for a supersonic particle swarm drive device. Background Technology

[0002] Supersonic particle swarm drive devices are designed to simulate the performance of certain materials and structures subjected to high-temperature, high-speed particle swarms. A supersonic particle swarm drive device mainly includes a main control unit, a high-temperature heat exchange medium heating device, a liquid pressurization device, a heat exchanger, and a jet injection device.

[0003] The design of a supersonic particle swarm drive device requires the use of a supersonic driving medium. After depressurization at the nozzle, rapid vaporization effectively reduces the interference of water and steam on downstream experiments, highlighting the particle swarm scouring effect and effectively controlling experimental interference factors. The heat exchanger, as an indispensable component of the drive device, is a crucial device for achieving rapid vaporization. Therefore, the heat exchanger must meet the following operating requirements: it must be capable of ultra-high temperature and ultra-high pressure heat exchange, possess high heat exchange efficiency and good safety performance, and also meet the requirements of compact structure and convenient maintenance.

[0004] Currently, there are various types of heat exchangers. For example, Chinese patent document CN116026171A discloses an ultra-high temperature and high pressure shell-and-tube heat exchanger, CN 111664427A discloses an ultra-high temperature and ultra-high pressure channel heat exchanger, and CN109654909B discloses a high temperature and high pressure micro-tube shell-and-tube heat exchanger. To meet the heat exchange requirements under high temperature and high pressure conditions, these technical solutions all design the heat exchange tubes and heat exchanger as a single unit. While this satisfies the requirements for ultra-high pressure and ultra-high temperature heat exchange, existing heat exchangers require complete installation and disassembly for maintenance, making the operation extremely inconvenient, time-consuming, and costly. Utility Model Content

[0005] The purpose of this invention is to solve the problems of inconvenient installation and maintenance, low efficiency, and high cost of heat exchangers in the prior art, and to provide a heat exchanger for a supersonic particle swarm drive device. It can achieve ultra-high temperature and high pressure heat exchange, has high heat exchange efficiency, compact structure, and is easy to install and maintain.

[0006] The technical solution adopted by this utility model to achieve its invention objective is as follows: a heat exchanger for a supersonic particle swarm drive device, comprising a heat exchanger shell with a high-pressure heat exchange chamber and an integrated heat exchange unit. The heat exchanger shell includes a shell body and an openable shell cover. The integrated heat exchange unit is integrated with the shell cover and includes multiple sets of independently circulating high-pressure spiral heat exchange tube units. This heat exchanger for a supersonic particle swarm drive device divides the heat exchanger shell into two parts: one part is the main body forming the high-pressure heat exchange chamber, i.e., the shell body, and the other part is the openable shell cover. The shell cover is designed to be openable, and the integrated heat exchange unit is connected to the shell cover as a whole. During installation, the shell body and the shell cover, along with the integrated heat exchange unit, can be installed step by step. After the shell body is installed, the shell cover and the integrated heat exchange unit are hoisted together and inserted into the high-pressure heat exchange chamber. Finally, the shell cover and the shell body are securely connected as a whole, thereby completing the installation operation of the heat exchanger. Similarly, during maintenance, only the integrated shell cover and the integrated heat exchange unit need to be lifted out together for repair, making the operation convenient and quick. The integrated heat exchange unit is not fixedly connected to the shell body; instead, it is integrated into the shell cover and operates together with it, facilitating on-site installation or disassembly for maintenance. To ensure heat exchange efficiency and meet the requirements of ultra-high pressure and high temperature heat exchange, the integrated heat exchange unit uses multiple sets of independently circulating high-pressure spiral heat exchange tube units. This allows for easy setting of the number of high-pressure spiral heat exchange units according to heat exchange efficiency requirements, and also enables individual testing of the heat exchange effect of each set of high-pressure spiral heat exchange tube units. If any set of high-pressure spiral heat exchange tube units is damaged and cannot function properly, that set of high-pressure spiral heat exchange tube units can be replaced, greatly reducing production costs. The design of the high-pressure spiral heat exchange tube units increases the heat exchange area and improves the heat exchange effect.

[0007] Preferably, the high-pressure spiral heat exchanger unit includes a spiral tube, a high-pressure spiral heat exchanger unit inlet, and a high-pressure spiral heat exchanger unit outlet. The high-pressure spiral heat exchanger unit mainly comprises a spiral tube through which a high-pressure liquid can flow. Preferably, the spiral tube is made of a high-pressure thin tube with an inner diameter of 2.5 mm and a length of 144 meters, arranged in a spiral structure. To facilitate the introduction of high-pressure liquid into the spiral tube, a high-pressure spiral tube unit inlet and a high-pressure spiral tube unit outlet are provided on the spiral tube, thereby achieving independent heat exchange circulation within the first spiral tube. The spiral tube can increase the heat exchange area, improve the heat exchange effect, and make the structure more compact.

[0008] Preferably, the spiral tube is configured as an integrated spiral tube sleeve structure, with the spiral tube sleeves in each high-pressure spiral heat exchanger tube unit arranged in a layered structure from the inside to the outside along the axis of the heat exchanger shell. The spiral tube is configured as a spiral sleeve structure, with the inner and outer sleeves of the spiral tubes in each high-pressure spiral heat exchanger tube unit forming an integrated heat exchange unit. This results in a compact structure, a large heat exchange area, and high heat exchange efficiency.

[0009] Preferably, all high-pressure spiral heat exchanger tube units have the same heat exchange area. In each group of high-pressure spiral heat exchanger tube units, the diameter of the spiral tube sleeve increases sequentially from the inside out, while the height of the spiral tube sleeve decreases sequentially from the inside out. Alternatively, in a preferred embodiment, each group of high-pressure spiral heat exchanger tube units has the same heat exchange area. Under this premise, the spiral tube sleeves in each group of high-pressure spiral heat exchanger tube units have different diameters and heights. From the inside out, the innermost spiral tube sleeve has the smallest diameter and the largest height, while the outermost spiral tube sleeve has the largest diameter and the smallest height.

[0010] Preferably, all high-pressure spiral heat exchanger tube units have different heat exchange areas, and the diameter of the spiral tube sleeve in each group of high-pressure spiral heat exchanger tube units increases sequentially from the inside to the outside, while the height of the spiral tube sleeve is the same. As another preferred option, the high-pressure spiral heat exchanger tube units can use different heat exchange areas. Under this premise, the diameter of the spiral tube sleeve can be different, but the height can be set to be the same, which can also meet the requirements of the inner and outer sleeve arrangement structure.

[0011] Preferably, the spiral tube is configured as an integral spiral tube disc structure, with the spiral tube discs in each high-pressure spiral heat exchanger tube unit stacked sequentially from top to bottom along the axis of the heat exchanger shell. Alternatively, the spiral tube can also be configured as a spiral tube disc structure; by stacking the spiral tube discs vertically, the heat exchange purpose can still be achieved, and the heat exchange area is larger, resulting in higher heat exchange efficiency.

[0012] Preferably, all high-pressure spiral heat exchanger tube units have the same heat exchange area, and the diameter of the spiral tube coils in each group of high-pressure spiral heat exchanger tube units is the same. All spiral tube coils have the same diameter, thus achieving the same heat exchange area.

[0013] Preferably, all high-pressure spiral heat exchanger tube units have different heat exchange areas, and the diameter of the spiral tube discs in each group of high-pressure spiral heat exchanger tube units increases sequentially from top to bottom. The diameter of the spiral tube discs can be arranged in an increasing structure from top to bottom.

[0014] Preferably, multiple sets of independently circulating high-pressure spiral heat exchanger tube units are integrated and fixed on a single high-pressure spiral heat exchanger tube unit fixing and lifting frame. This single frame allows for the integrated installation of all high-pressure spiral heat exchanger tube units and the housing cover, facilitating the opening and hoisting of the integrated heat exchanger unit and housing cover together, thus simplifying installation and maintenance.

[0015] Preferably, the high-pressure spiral heat exchanger tube unit fixing and lifting frame includes an upper tube frame plate, a tube frame support and fixing body, and a lower tube frame plate, with several tube fixing components evenly distributed on the tube frame support and fixing body. This structure facilitates the axial and radial fixing of the spiral tube and allows for movable insertion into the high-pressure heat exchange chamber without requiring a fixed connection to the shell body, greatly simplifying installation and maintenance.

[0016] Preferably, the upper surface of the tray on the tube rack is provided with several tray fixing components and tray support components. The tray fixing components are provided to facilitate the fixed connection with the shell cover, while the tray support components are provided to increase the contact support area between the tray on the tube rack and the shell cover, thereby increasing stability.

[0017] Preferably, a support frame is integrally formed inside the shell cover, and the integrated heat exchange unit is fixedly connected to the support frame to form an integral structure with the shell cover. The support frame facilitates the connection of the trays on the tube rack.

[0018] Preferably, at least one high-temperature heat exchange medium inlet is provided on the side wall of the shell body, and at least one low-temperature heat exchange medium outlet is provided at the bottom of the shell body. The high-temperature heat exchange medium inlet and the low-temperature heat exchange medium outlet facilitate the entry of the high-temperature heat exchange medium into the high-pressure heat exchange chamber, where it undergoes heat exchange and then circulates. Preferably, to increase the flow rate and velocity, two high-temperature heat exchange medium inlets and two low-temperature heat exchange medium outlets are provided.

[0019] Preferably, the heat exchanger shell is also equipped with a pressure gauge, thermometer, thermocouple and safety valve interface.

[0020] The beneficial effects of this utility model are: the heat exchanger for the supersonic particle swarm drive device has an openable shell cover and connects the integrated heat exchange unit to the shell cover as one unit, which greatly facilitates installation, disassembly and maintenance operations.

[0021] The integrated heat exchange unit adopts multiple sets of independent circulating high-pressure spiral heat exchange tube units, which have a compact structure, large heat exchange area, and high heat exchange efficiency. It is convenient to set the number of high-pressure spiral heat exchange units according to the heat exchange efficiency requirements, and it can also realize the individual testing of the heat exchange effect of each set of high-pressure spiral heat exchange tube units. If any set of high-pressure spiral heat exchange tube units is damaged and cannot work properly, the set of high-pressure spiral heat exchange tube units can be replaced, which greatly reduces production costs.

[0022] The heat exchanger is designed to meet the requirements of supersonic particle swarm drive. After heat exchange, the ultra-high temperature and high pressure liquid can be rapidly vaporized after depressurization in the nozzle to reduce the interference of water and water vapor on the downstream experiment, highlight the particle swarm scouring effect, effectively control experimental interference factors, and achieve high energy transfer and particle swarm acceleration effect without the need for additional heating or compression.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0045] Example 1: In Figure 1, Figure 2 , Figure 3 In the embodiment shown, a heat exchanger for a supersonic particle swarm drive device includes a heat exchanger housing 1 and an integrated heat exchange unit 2 integrated inside the heat exchanger housing 1.

[0046] The heat exchanger shell 1 is cylindrical in shape and is made entirely of high-pressure resistant material. A high-pressure heat exchange chamber 4 is located inside the heat exchanger shell 1.

[0047] The heat exchanger housing 1 includes a housing cover 11 and a housing body 12. The housing cover 11 has a housing cover cavity 111 inside, and the housing body has a housing body cavity 121 inside. The housing cover cavity 111 and the housing body cavity 121 are sealed to form the high-pressure heat exchange chamber 4.

[0048] like Figure 10 , Figure 11 As shown, the housing cover 11 includes an arc-shaped housing cover 13 and a housing cover flange 14 disposed on the arc-shaped housing cover 13. A support frame 18 is integrally disposed inside the housing cover cavity, and the integrated heat exchange unit is fixedly connected to the support frame 18, thus forming an integral structure with the housing cover. In this embodiment, the support frame 18 is generally arranged in a truncated ring structure on the cavity wall of the housing cover cavity. Multiple fixing holes are evenly distributed on the support frame 18.

[0049] like Figure 4 , Figure 5As shown, the integrated heat exchange unit 2 is integrated with the housing cover 11 as one unit, and the integrated heat exchange unit 2 is movably inserted into the high-pressure heat exchange chamber 4. The integrated heat exchange unit 2 is not fixed to the inner wall of the high-pressure heat exchange chamber 4, so that the integrated heat exchange unit 2 can be disassembled and assembled together with the housing cover 11.

[0050] like Figure 12 , Figure 13 , Figure 14 As shown, the shell body 12 includes an integrally formed arc-shaped bottom shell 15 and a cylindrical main shell 16. The cylindrical main shell 16 has a shell body flange 17 at its open end. The shell cover 11 and the shell body 12 are sealed together by the shell cover flange 14 and the shell body flange 17, and are fastened together by fasteners 3, thereby forming a high-pressure heat exchange chamber 4 inside the heat exchanger shell 1.

[0051] like Figure 6 As shown, the integrated heat exchange unit 2 includes multiple sets of independently circulating high-pressure spiral heat exchange tube units 6 and a high-pressure spiral heat exchange tube unit fixing and lifting frame 7 for fixing the high-pressure spiral heat exchange tube units.

[0052] like Figure 6 , Figure 7 , Figure 8 As shown in this embodiment, each high-pressure spiral heat exchanger tube unit 6 includes an integrally formed spiral tube 61. The spiral tube 61 is arranged in an integral spiral tube sleeve structure. The spiral tube sleeves in each high-pressure spiral heat exchanger tube unit 6 are arranged in a layered structure from the inside to the outside along the axis of the heat exchanger shell. All high-pressure spiral heat exchanger tube units 6 have the same heat exchange area. The diameter of the spiral tube sleeves in each high-pressure spiral heat exchanger tube unit 6 increases sequentially from the inside to the outside, and the height of the spiral tube sleeves decreases sequentially from the inside to the outside.

[0053] The high-pressure spiral heat exchanger tube unit 6 can withstand high pressures up to 600GP. Each high-pressure spiral heat exchanger tube unit 6 is set up independently in a loop. The high-pressure spiral heat exchanger tube unit 6 also includes a high-pressure spiral heat exchanger tube unit inlet 62 and a high-pressure spiral heat exchanger tube unit outlet 63, which are set outside the shell cover and connected to both ends of the spiral tube to form an independent loop. The high-pressure spiral heat exchanger tube unit inlet 62 and the high-pressure spiral heat exchanger tube unit outlet 63 are respectively set on the outer arc-shaped end face of the shell cover 11.

[0054] In this embodiment, each group of high-pressure spiral heat exchanger tube units has the same heat exchange area, and the spiral tube sleeves in each group of high-pressure spiral heat exchanger tube units have different diameters and heights.

[0055] Specifically, the spiral sleeve is made of a pipe with an inner diameter of 2.5 mm and a total length of 144 meters. The spiral pipe 61 is set up as a spiral sleeve structure.

[0056] The spiral tubes 61 in the multiple sets of independently circulating high-pressure spiral heat exchanger tube units 6 are respectively configured with spiral tube sleeves of different diameters. The diameter of the spiral tube sleeve in the inner high-pressure spiral heat exchanger tube unit 6 is smaller than that in the outer high-pressure spiral heat exchanger tube unit 6, and the height of the spiral tube sleeve in the inner high-pressure spiral heat exchanger tube unit 6 is greater than that in the outer high-pressure spiral heat exchanger tube unit 6. This forms an arrangement structure in which the diameter of the spiral tube sleeve increases sequentially from the inside to the outside, and the height of the spiral tube sleeve decreases sequentially. This ensures sufficient heat exchange area while increasing flow rate and heat exchange efficiency.

[0057] In this embodiment, four sets of high-pressure spiral heat exchanger tube units 6 are provided, namely the first high-pressure spiral heat exchanger tube unit 6-1, the second high-pressure spiral heat exchanger tube unit 6-2, the third high-pressure spiral heat exchanger tube unit 6-3, and the fourth high-pressure spiral heat exchanger tube unit 6-4. The specific number is not limited and can be arranged according to the actual heat exchange needs. The first high-pressure spiral heat exchanger tube unit 6-1, the second high-pressure spiral heat exchanger tube unit 6-2, the third high-pressure spiral heat exchanger tube unit 6-3, and the fourth high-pressure spiral heat exchanger tube unit 6-4 are arranged in an inner and outer sleeve structure along the axis of the high-pressure heat exchange chamber 4.

[0058] like Figure 9 As shown, the integrated detachable high-pressure spiral heat exchanger tube unit fixing and lifting frame 7 includes an upper plate 71, a tube support fixing body 72, and a lower plate 73. The upper plate 71 and the lower plate 73 are arranged symmetrically. The upper plate 71 and the lower plate 73 are respectively provided with an inner ring support 74, a radial support 75, and an outer ring support 76. In this embodiment, the radial support 75 is provided in three sets and is evenly distributed between the inner ring support 74 and the outer ring support 76, thereby forming a support for multiple sets of high-pressure spiral heat exchanger tube units 6.

[0059] The tube rack support and fixing body 72 is axially disposed between the lower tube rack disc 73 and the upper tube rack disc 71. A plurality of tube fixing members 77 are evenly distributed on the tube rack support and fixing body 72 for fixing and positioning the high-pressure spiral heat exchange tube unit 6. In this embodiment, the tube fixing members 77 are U-shaped locking members. The tube rack support and fixing body 72 includes an outer tube rack support and fixing body 721 and an inner tube rack support and fixing body 722. Three sets of the outer tube rack support and fixing bodies 721 are evenly distributed on the outer ring support 76 of the disc. The inner tube rack support and fixing bodies 722 are disposed on the radial support 75 of the disc.

[0060] On the upper surface of the disc 71 on the tube rack, several disc fixing members 78 and disc support members 79 are provided. The high-pressure spiral heat exchange tube unit fixing and lifting frame 7 is fixedly connected to the inner wall of the shell cover 11 through the disc fixing members 78, forming an integral structure with the shell cover 11. The disc support members 79 provide a stable support structure between the disc 71 on the tube rack and the support fixing frame 18 inside the shell cover. In this embodiment, the disc fixing members 78 are generally L-shaped, with fixing holes provided on the disc fixing members 78 and corresponding fixing holes provided on the support fixing frame 18. The disc fixing members and the support fixing frame are fastened together by fixing bolts.

[0061] At least one high-temperature heat exchange medium inlet 8 is provided on the side wall of the shell body 12, and at least one low-temperature heat exchange medium outlet 9 is provided at the bottom of the shell body 12.

[0062] In this embodiment, two high-temperature heat exchange medium inlets 8 are provided, and two corresponding low-temperature heat exchange medium outlets 9 are also provided. Specifically, the high-temperature heat exchange medium inlets 8 are connected to the shell body 12 via high-temperature heat exchange medium inlet pipes, and the low-temperature heat exchange medium outlets 9 are connected to the shell body 12 via low-temperature heat exchange medium outlet pipes.

[0063] The high-temperature heat exchange medium inlet 8 and the low-temperature heat exchange medium outlet 9 are connected to an external high-temperature heat exchange medium device, used to circulate and supply high-temperature heat exchange medium into the high-pressure heat exchange chamber 4. The high-temperature heat exchange medium can be high-temperature heat exchange water, high-temperature heat exchange steam, or a high-temperature water-vapor mixture of high-temperature heat exchange water and high-temperature heat exchange steam. In this embodiment, a high-temperature water-vapor mixture of high-temperature heat exchange water and high-temperature heat exchange steam is used.

[0064] The temperature of high-temperature heat exchange medium can reach 300℃, and the pressure is generally within 9.8GP, while the pressure of high-pressure cooling water can reach up to 600GP.

[0065] like Figure 15 , 16 As shown, during use, a high-temperature water-steam mixture is introduced into the high-pressure heat exchange chamber through the high-temperature heat exchange medium inlet pipe. At this time, a mixed heat exchange state is formed inside the high-pressure heat exchange chamber, with high-temperature heat exchange steam in the upper part and high-temperature heat exchange water in the lower part, to exchange heat with the high-pressure cooling water inside the high-pressure spiral heat exchange tube unit.

[0066] The high-temperature heat exchange steam in the upper part occupies about one-quarter of the upper volume of the high-pressure heat exchange chamber, while the high-pressure heat exchange water occupies about three-quarters of the lower volume of the high-pressure heat exchange chamber.

[0067] A pressure gauge 20 and a thermometer 30 are also installed on the top of the housing cover 11. These pressure gauges and thermometers are specialized and suitable for high pressure and high temperature applications. A thermocouple 40 is also included, which directly measures the temperature and converts the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium by an electrical instrument. A safety valve port 10 is located along the axis at the center of the housing cover for connecting a safety valve to ensure the safe operation of the heat exchanger.

[0068] Example 2: exist Figure 17 , Figure 18 In the embodiment shown, the heat exchanger for a supersonic particle swarm drive device has a technical solution that is basically the same as that in Embodiment 1, except that: Each high-pressure spiral heat exchanger tube unit 6 includes an integrally formed spiral tube 61. The spiral tube 61 is arranged in an integral spiral tube sleeve structure. The spiral tube sleeves in each high-pressure spiral heat exchanger tube unit 6 are arranged in a layered structure from the inside to the outside along the axis of the heat exchanger shell. All high-pressure spiral heat exchanger tube units 6 have different heat exchange areas. The diameter of the spiral tube sleeves in each high-pressure spiral heat exchanger tube unit 6 increases sequentially from the inside to the outside, and the height of the spiral tube sleeves is the same.

[0069] Specifically, the spiral pipe sleeve is made of pipe fittings with an inner diameter of 2.5 mm and a total length of no more than 144 meters, and the spiral pipe 61 is set in a spiral sleeve structure. Spiral pipe sleeves of different diameters are made of pipe fittings of different lengths.

[0070] The spiral tubes 61 in the multiple sets of independently circulating high-pressure spiral heat exchanger tube units 6 are respectively configured with spiral tube sleeves of different diameters. The diameter of the spiral tube sleeve in the high-pressure spiral heat exchanger tube unit 6 located on the inner side is smaller than the diameter of the spiral tube sleeve in the high-pressure spiral heat exchanger tube unit 6 located on the outer side, thereby forming a layout structure in which the diameter of the spiral tube sleeve increases sequentially from the inside to the outside, and the spiral tube sleeves have the same height. This ensures sufficient heat exchange area while increasing flow rate and heat exchange efficiency.

[0071] The high-pressure spiral heat exchanger tube unit 6 can withstand high pressures up to 600GP. Each high-pressure spiral heat exchanger tube unit 6 is set up independently in a loop. The high-pressure spiral heat exchanger tube unit 6 also includes a high-pressure spiral heat exchanger tube unit inlet 62 and a high-pressure spiral heat exchanger tube unit outlet 63, which are set outside the shell cover and connected to both ends of the spiral tube to form an independent loop. The high-pressure spiral heat exchanger tube unit inlet 62 and the high-pressure spiral heat exchanger tube unit outlet 63 are respectively set on the outer arc-shaped end face of the shell cover 11.

[0072] Example 3: exist Figure 19 , Figure 20The technical solutions in the embodiments shown are basically the same as those in Embodiment 1 or Embodiment 2, except that: The high-pressure spiral heat exchanger unit 6 includes a spiral tube 61, a high-pressure spiral heat exchanger unit inlet 62, and a high-pressure spiral heat exchanger unit outlet 63.

[0073] See Figure 20 The spiral tube 61 is an integral spiral tube disc structure, and the spiral tube discs in each group of high-pressure spiral heat exchange tube units 6 are stacked sequentially from top to bottom along the axis of the heat exchanger shell. The number of spiral tube discs can be designed according to actual needs. In this embodiment, there are 11 groups of spiral tube discs, and each group of spiral tube discs circulates independently.

[0074] In this embodiment, all high-pressure spiral heat exchanger tube units 6 have the same heat exchange area, and the diameter of the spiral tube disc in each group of high-pressure spiral heat exchanger tube units 6 is the same.

[0075] In another embodiment, all high-pressure spiral heat exchanger tube units have different heat exchange areas, and the diameter of the spiral tube disc in each group of high-pressure spiral heat exchanger tube units 6 increases sequentially from top to bottom.

[0076] All the spiral tube coils in the independent circulating high-pressure spiral heat exchanger tube units 6 are mounted on a high-pressure spiral heat exchanger tube unit fixed lifting frame 7, and integrated into a single structure.

[0077] like Figure 15 , Figure 16 As shown in the above embodiment, the heat exchanger for a supersonic particle swarm drive device, in use, has its high-pressure spiral heat exchanger tube unit inlet 62 connected to a liquid pressurization device. A liquid, such as water, is pressurized to below 600 MPa by the liquid pressurization device. The specific pressure can be freely adjusted as needed, for example, to 500 MPa, thereby forming a high-pressure liquid. The high-pressure liquid enters the high-pressure spiral heat exchanger tube unit 6 through the high-pressure spiral heat exchanger tube unit inlet 62, where heat exchange occurs inside the high-pressure heat exchange chamber 4.

[0078] The high-temperature heat exchange medium inlet 8 and the low-temperature heat exchange medium outlet 9 are respectively connected to the external high-temperature heat exchange medium heating device 5 through pipelines. The high-temperature heat exchange medium heating device can be, for example, a high-temperature electric thermal storage furnace. The high-temperature heat exchange medium is transported into the high-pressure heat exchange chamber 4 through the high-temperature electric thermal storage furnace. The high-temperature heat exchange medium exchanges heat with the high-pressure liquid inside the high-pressure spiral heat exchange tube unit, heating the high-pressure liquid to a maximum of 300°C, preferably to the required 227°C~277°C, forming an ultra-high temperature and high-pressure liquid. After the ultra-high temperature and high-pressure liquid is depressurized in the nozzle, it can quickly vaporize to reduce the interference of water and water vapor on the downstream experiment, highlight the particle swarm scouring effect, effectively control experimental interference factors, and achieve high energy transfer and particle swarm acceleration effect without additional heating or compression.
