Figure 2 for Figure 1 Cross-section along AA. Figure 4 A schematic diagram of a pressure fluctuation suppression structure provided by another embodiment of the present invention. A pressure fluctuation suppression structure 10 provided by an embodiment of the present invention comprises: a connecting pipeline 100, a hedging joint 200 and an adjusting component 300; the connecting pipeline 100 comprises an inlet pipe 110 and an outlet pipe 120 arranged at intervals, and the inlet of the inlet pipe 110 is used to allow air flow; the hedging joint 200 comprises at least two hedging pipes 210 arranged circumferentially around the outlet of the inlet pipe 110, and each hedging pipe 210 has an inlet port 211 and an outlet port 212 at both ends, and each hedging pipe 210 has an inlet port 211 and an outlet port 212 at both ends. The air inlet 211 of the hedging tube 210 is connected to the outlet of the air inlet pipe 110, the air outlet 212 of each hedging tube 210 is connected to the inlet of the air outlet pipe 120, and the air outlet 212 of at least two hedging tubes 210 are at least partially aligned to allow the airflow flowing out through the air outlet 212 to be offset; the adjusting component 300 is connected to the hedging joint 200, and the adjusting component 300 is used to apply a force to the hedging joint 200 to change the flow direction of the airflow discharged from the air outlet 212.

[0041] Specifically, the hedging section 200 of the present application includes at least two hedging tubes 210 circumferentially arranged around the outlet of the air inlet pipe 110, and the air inlet 211 of each hedging tube 210 is connected to the outlet of the air inlet pipe 110, so that the airflow entering through the air inlet pipe 110 is divided into multiple airflows, and the air outlets 212 of at least two hedging tubes 210 are at least partially aligned, so that the airflows flowing out through the air outlets 212 can meet and collide, so that the airflow velocity is reduced, and the pressure fluctuation energy is offset and absorbed, so as to achieve a substantial reduction in the kinetic energy of the fluctuating flow, so that the air outlet pipe 120 outputs a relatively smooth airflow, and a force is applied to the hedging section 200 through the adjustment component 300, so as to change the flow direction of the airflow discharged from the air outlet 212 to adjust the airflow collision angle, thereby achieving the adjustment of the degree of reduction of the kinetic energy of the fluctuating flow, and improving the adaptability of the pressure fluctuation suppression structure 10.

[0042] See also Figure 1 and Figure 2 In one embodiment, the air outlets 212 of each hedging tube 210 are aligned in a first direction parallel to the circumference of the outlet of the air inlet pipe 110, thereby increasing the intensity of the airflow hedging out through the air outlet 212, improving the degree of reduction of the kinetic energy of the fluctuating flow, and improving the ability of the pressure fluctuation suppression structure 10 to suppress pressure fluctuations.

[0043] Furthermore, the number of the hedging tubes 210 is an even number, and they are arranged opposite to each other in pairs, so as to ensure that the airflows flowing out through the air outlets 212 will be counteracted in pairs, thereby increasing the intensity of the counteraction, thereby being able to significantly reduce the fluctuation kinetic energy, and improving the performance of the pressure fluctuation suppression structure 10 in suppressing pressure fluctuations. Preferably, in this embodiment, the number of the hedging tubes 210 is four, and they are evenly spaced around the circumference of the outlet of the air inlet pipe 110.

[0044] The air inlet pipe 110 and the air outlet pipe 120 both extend along the second direction, and the second direction is perpendicular to the circumferential direction of the outlet of the air inlet pipe. It should be noted that the present application uses the example of water vapor as an example for description, but is not limited to the example.

[0045] See also Figure 1 and Figure 2 In one embodiment, the hedging section 200 further includes a first expansion chamber 221 and a collision plate 230. The two ends of the first expansion chamber 221 are respectively connected to the outlet of the air inlet pipe 110 and each air inlet 211. The collision plate 230 is accommodated in the first expansion chamber 221 and abuts against the side of the cavity wall of the first expansion chamber 221 away from the air inlet pipe 110. The collision plate 230 is used to collide with the airflow.

[0046] Specifically, each air inlet 211 is located on a side of the collision plate 230 close to the air inlet pipe 110, so that the airflow entering through the air inlet pipe 110 first collides with the collision plate 230, and then flows into the collision pipe 210 through the air inlet 211. The collision of the airflow with the collision plate 230 can slow down the flow rate of the airflow and change the flow trajectory of the airflow, thereby achieving the elimination of part of the airflow fluctuation kinetic energy, further achieving a significant reduction in the fluctuation kinetic energy, and improving the performance of the pressure fluctuation suppression structure 10 in suppressing pressure fluctuations.

[0047] Furthermore, in the first direction, the side of each air inlet 211 away from the air inlet pipe 110 is flush with the collision plate 230, so that more airflow collides with the collision plate 230 first, and then flows into the hedge pipe 210 through the air inlet 211, thereby improving the reliability of the pressure fluctuation suppression structure 10.

[0048] See also Figure 1 and Figure 2In one embodiment, the pressure fluctuation suppression structure 10 further includes a diverter block 240, which is accommodated in the first expansion chamber 221 and connected to the collision plate 230. In the direction from the air inlet pipe 110 to the air outlet pipe 120, the outer contour size of the diverter block 240 gradually expands.

[0049] Specifically, the diverter block 240 is located on the side of the collision plate 230 close to the intake pipe 110, and the diverter block 240 can play a guiding role, so that the airflow in the first expansion cavity 221 can flow to each hedging pipe 210 to achieve hedging. It should be noted that part of the airflow entering through the intake pipe 110 will collide with the diverter block 240, which plays a role in slowing down the flow rate of the airflow and eliminating part of the kinetic energy of the airflow fluctuation.

[0050] Furthermore, the side of the diverter block 240 close to the air inlet pipe 110 is a pointed end, so as to facilitate flow diversion. Preferably, the diverter block 240 is conical.

[0051] See also Figure 1 and Figure 2 In one of the embodiments, in the direction from the air inlet pipe 110 to the air outlet pipe 120, the inner contour size of the first expansion chamber 221 gradually expands, that is, the inner contour of the first expansion chamber 221 is an isosceles trapezoid, and the area corresponding to the cavity wall and the waist edge of the first expansion chamber 221 can collide again with part of the countercurrent airflow after the collision with the collision plate 230, so as to slow down the flow rate of the airflow, eliminate part of the kinetic energy of the airflow fluctuation, and play a role in guiding the countercurrent airflow after the collision to flow into the hedging pipe 210.

[0052] Furthermore, the pressure fluctuation suppression structure 10 includes a first expansion box 220 , a first expansion chamber 221 is disposed in the first expansion box 220 , and each of the hedge pipes 210 is connected to the first expansion box 220 .

[0053] See also Figure 1 and Figure 2 In one embodiment, the hedging section 200 further includes a second expansion chamber 251, which is connected to the inlet of the air outlet pipe 120 and each air outlet 212, thereby providing energy consumption space and flow posture adjustment space for airflow hedging.

[0054] See also Figure 1 , Figure 2 and Figure 3 , Figure 3A left view of a pressure fluctuation suppression structure provided in one embodiment of the present invention. In one embodiment, the hedge pipe 210 includes a connecting pipe 215, a first hose 216 and a second hose 217, the first hose 216 and the second hose 217 are respectively connected to both ends of the connecting pipe 215, the air outlet 212 is provided on the first hose 216, and the adjustment component 300 is connected to the connecting pipe 215, and the adjustment component 300 is used to drive the connecting pipe 215 to move so as to change the extension direction of the first hose 216.

[0055] Specifically, the adjustment assembly 300 is connected to the connecting tube 215 between the first hose 216 and the second hose 217, and by driving the connecting tube 215 to move, the first hose 216 and the second hose 217 can be deformed, thereby changing the angle of the air outlet 212 and the impact angle of the airflow, so as to adjust the degree of reduction of the kinetic energy of the fluctuating flow, realize effective control of the pressure loss, and improve the adaptability of the pressure fluctuation suppression structure 10. Preferably, the first hose 216 and the second hose 217 are bellows.

[0056] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the adjustment assembly 300 includes a driving member 310 and a connecting rod 320, any two adjacent hedge tubes 210 are connected by a connecting rod 320, the driving member 310 is connected to a connecting rod 320, and the driving member 310 is used to drive the connecting rod 320 to move along a second direction, wherein the second direction is perpendicular to the circumference of the outlet of the intake pipe 110.

[0057] Specifically, the connecting rod 320 is driven to move along the second direction by the driving member 310, so that the connecting rod 320 can drive each connecting tube 215 to move along the second direction, thereby realizing the synchronous movement of each connecting tube 215 along the second direction, so as to adjust the angle of the air outlet 212 of each hedging tube 210, thereby improving the efficiency and convenience of adjusting the airflow hedging angle.

[0058] Among them, since each air outlet 212 is aligned in the first direction, the connecting pipes 215 are driven to move along the second direction through the connecting rod 320 to synchronously adjust the angles of each air outlet 212, thereby ensuring that each air outlet 212 is aligned, ensuring the impact of airflow, and improving the reliability of the pressure fluctuation suppression structure 10.

[0059] Furthermore, the adjustment assembly 300 also includes a fixing ring 330 , which is sleeved on the connecting pipe 215 and connected to the connecting pipe 215 , and the connecting rod 320 is connected to the fixing ring 330 , thereby improving the stability of the connection between the connecting rod 320 and the connecting pipe 215 .

[0060] See also Figure 1 and Figure 2In one embodiment, the hedge tube 210 has at least one bend 213, so that the airflow can collide, slow down the airflow velocity, eliminate part of the airflow fluctuation kinetic energy, and improve the performance of the pressure fluctuation suppression structure 10 in suppressing pressure fluctuations.

[0061] Furthermore, the hedge pipe 210 also includes a fixed pipe 214 connected to the second hose 217 . The fixed pipe 214 has two bends 213 . The air inlet 211 is located on the fixed pipe 214 .

[0062] See also Figure 1 , Figure 2 and Figure 4 In one embodiment, the number of the hedging sections 200 is at least two, and two adjacent hedging sections 200 are connected via a connecting pipe 260 .

[0063] Specifically, the second expansion box 250 of one of the two adjacent hedging sections 200 is connected to the connecting pipe 260, and the first expansion box 220 of the other one is connected to the connecting pipe 260. By having at least two hedging sections 200, the velocity and pressure fluctuation amplitude of the airflow can be weakened multiple times, thereby effectively eliminating the kinetic energy of the airflow fluctuation and fundamentally suppressing the airflow pressure fluctuation.

[0064] Furthermore, the adjustment assembly 300 also includes a control rod 340, which is connected to the driving member 310, and the control rod 340 is connected to a corresponding connecting rod 320 on each hedging joint 200, so that the hedging angle on each hedging joint 200 can be adjusted by driving the driving member 310, thereby improving the efficiency of adjusting the hedging angle and improving the convenience of the pressure fluctuation suppression structure 10.

[0065] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 , Figure 5 Schematic diagram of a pressure stabilizer provided by an embodiment of the present invention. In one embodiment, the present invention further provides a pressure stabilizer 400, including the pressure fluctuation suppression structure 10 described above, and also including an outer cylinder 410, the outer cylinder 410 has a receiving cavity 411, the pressure fluctuation suppression structure 10 is accommodated in the receiving cavity 411, and the outer cylinder 410 has an air inlet 412 and an air outlet 413 connected to the receiving cavity 411.

[0066] Specifically, the air inlet 412 is used to introduce medium gas, which is mixed with water vapor in the accommodating chamber 411 and then flows out through the air outlet 413. Since the air flow fluctuation kinetic energy of the water vapor flowing out through the air outlet pipe 120 is eliminated, the air flow pressure of the water vapor is very small. By controlling the air pressure of the gas medium introduced into the air inlet 412, the air pressure of the air flow flowing out through the air outlet 413 can be adjusted and the flow can be stabilized, so that it can be applied to solid oxide electrolysis hydrogen production systems and solid oxide fuel cell power generation systems of various power models, and has universal applicability.

[0067] The offset joint 200 is accommodated in the accommodating cavity 411 , and a portion of the air inlet pipe 110 is located outside the accommodating cavity 411 , thereby facilitating the inflow of air.

[0068] See also Figure 4 and Figure 5 In one embodiment, the air inlet 412 is located on a side close to the air outlet pipe 120, and the air outlet 413 is located on a side close to the air inlet pipe 110, so that the air flow flowing out through the air outlet 212 can be easily mixed with the gas medium, and when it is discharged through the air outlet 413, it has a sufficient path for uniform mixing, thereby improving the reliability of the regulator 400.

[0069] See also Figure 4 and Figure 5 In one embodiment, the regulator 400 further includes a boss 430, which is connected to one end of the outer tube 410 away from the air inlet pipe 110, and a buffer cavity 431 connected to the accommodating cavity 411 is constructed in the boss 430. In the direction from the air inlet pipe 110 to the air outlet pipe 120, the inner contour size of the buffer cavity 431 gradually decreases, so that the airflow flowing out through the air outlet pipe 120 collides in the buffer cavity 431 and flows back, thereby facilitating mixing with the medium gas.

[0070] Furthermore, the voltage stabilizer 400 further includes a plurality of support columns 420 disposed around the circumference of the outer cylinder 410 . The support columns 420 are connected to the bottom of the outer cylinder 410 to support the outer cylinder 410 .

[0071] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 An embodiment of the present invention further provides a solid oxide energy conversion system, including the above-mentioned pressure fluctuation suppression structure 10, or including the above-mentioned regulator 400.

[0072] Specifically, the present application aligns the air outlet 212 of the hedging tube 210 so that the airflows flowing out through the air outlet 212 can meet and collide with each other, thereby reducing the airflow velocity and offsetting each other's absorption of pressure fluctuation energy, thereby achieving a substantial reduction in the kinetic energy of the fluctuating flow, thereby outputting a relatively smooth airflow, and applying a force to the hedging section 200 through the adjustment component 300, thereby changing the flow direction of the airflow discharged from the air outlet 212 to adjust the airflow collision angle, thereby achieving the adjustment of the degree of reduction in the kinetic energy of the fluctuating flow, thereby improving the reliability of the solid oxide energy conversion system.

[0073] Among them, when the solid oxide energy conversion system is applied to hydrogen production, it is a solid oxide electrolysis hydrogen production system, and the gas medium is hydrogen, which is used to provide a reaction medium; when the solid oxide energy conversion system is applied to power generation, it is a solid oxide fuel cell power generation system, and the gas medium is fuel gas, which is used to provide energy.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
