Description

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figure 1-10 As shown, the steam pressure matcher of the embodiment of the present invention includes a first pipeline 1, a compressor 2 and an energy supply component 3.

[0033] The first pipeline 1 has a first flow channel 17 therein, and the first flow channel 17 has an inlet 11 and an outlet 12. The compressor 2 is connected to the first pipeline 1, and the compressor 2 is arranged adjacent to the inlet 11. The compressor 2 includes a plurality of impellers 21 and a first rotating shaft 22. The plurality of impellers 21 are respectively connected to the first rotating shaft 22. The plurality of impellers 21 are arranged along the length direction of the first pipeline 1 (e.g., Figure 1 The first rotating shaft 22 is arranged at intervals in the left and right directions (shown in the figure), the first rotating shaft 22 is arranged in the first pipeline 1, the first rotating shaft 22 is rotatable relative to the first pipeline 1, and the dimensions of the plurality of impellers 21 in the radial direction of the first rotating shaft 22 gradually decrease in the direction away from the inlet 11 in the length direction of the first pipeline 1. The energy supply component 3 is connected to the compressor 2 to drive the compressor 2 to rotate. The adjustment component 7 includes an adjustment disk 71, which is sleeved on the first rotating shaft 22, and the adjustment disk 71 is connected to one end of the impeller 21 to adjust the position of the impeller 21 on the adjustment disk 71.

[0034] Specifically, low-pressure steam flows into the first flow channel 17 through the inlet 11 of the first flow channel 17, and medium-pressure steam flows out of the first pipeline 1 through the outlet 12 of the first flow channel 17. The compressor 2 is arranged near the inlet 11 of the low-pressure steam, and the energy supply component 3 is connected to the compressor 2, which can provide power for the compressor 2, so that the compressor 2 rotates to drive the low-pressure steam to rotate, thereby pressurizing the low-pressure steam.

[0035] Specifically, the adjusting disk 71 is connected to one end of the impeller 21, and the position of the impeller 21 is adjusted by the adjusting disk 71 to change the position of the impeller 21 in the first pipeline 1, that is, when the compressor 2 is required to be used for pressurization, the position of the impeller 21 in the first pipeline 1 is adjusted so that the impeller 21 can be fully in contact with the gas, thereby improving the rotation efficiency of the impeller 21 and thus improving the pressurization efficiency. When the compressor 2 is not required to be used for pressurization, the impeller 21 is adjusted so that the blade surface of the impeller 21 is consistent with the gas flow direction in the first pipeline 1, thereby reducing the energy consumption of the impeller on the gas, thereby improving the efficiency of the steam pressure matcher.

[0036] Optionally, the plurality of impellers 21 are respectively connected to the first rotating shaft 22, so that when the first rotating shaft 22 rotates, the plurality of impellers 21 can be driven to rotate. The boosting capacity of each impeller 21 is limited. By setting the number of impellers 21 to be multiple, the boosting effect of the impeller 21 is improved, and the plurality of impellers 21 are arranged at intervals in the left-right direction, so that the plurality of impellers 21 can achieve multi-stage pressurization of the low-pressure steam, thereby improving the boosting effect of the compressor 2 on the low-pressure steam, and further improving the pressurization efficiency of the steam pressure matcher.

[0037] Optionally, the number of impellers 21 can be set according to actual usage requirements, for example, the number of impellers 21 is set to three, four, or five.

[0038] Specifically, the radial dimensions of the plurality of impellers 21 along the first rotating shaft 22 from left to right decrease in sequence. After the first impeller 21 on the left side of the first rotating shaft 22 compresses the low-pressure steam, the density of the low-pressure steam increases and the volume becomes smaller.

[0039] Optionally, the volume of low-pressure steam when entering the first impeller 21 is greater than the volume of low-pressure steam when entering the second impeller 21, and the volume of low-pressure steam when entering the second impeller 21 is greater than the volume of low-pressure steam when entering the third impeller 21, and so on, until the low-pressure steam enters the last impeller 21, the volume of low-pressure steam entering the penultimate impeller 21 is greater than the volume of low-pressure steam entering the last impeller 21, and the last impeller 21 compresses the low-pressure steam and outputs it, that is, multiple impellers 21 compress the low-pressure steam to increase the pressure of the low-pressure steam. Compared with the heating method in the related technology that requires a large amount of energy consumption, this embodiment uses the mechanical rotation of the impeller 21 to pressurize the low-pressure steam, which can reduce the pressurization cost.

[0040] Optionally, the low-pressure steam is pressurized step by step through multiple impellers 21, the volume of the low-pressure steam will become smaller and smaller, and the flow area of ​​the low-pressure steam in the impeller 21 will also become smaller and smaller. Setting multiple impellers 21 with smaller and smaller radial dimensions can improve the pressurization effect of the impeller 21, thereby improving the pressurization efficiency of the steam pressure matcher.

[0041] In the embodiment of the present invention, a compressor 2 is arranged to pressurize the low-pressure steam. When the compressor 2 rotates, it compresses the low-pressure steam at the inlet 11 of the first pipeline 1 to pressurize the low-pressure steam. The energy supply component 3 is arranged to provide kinetic energy to the compressor 2 to avoid energy loss in the steam pressure matcher, thereby increasing the pressure of the medium-pressure steam flowing out of the first flow channel 17.

[0042] Optionally, the inlet 11 of the first flow channel 17 is connected to a low-pressure steam source, and the low-pressure steam source transmits low-pressure steam into the first flow channel 17 through the inlet 11 of the first flow channel 17. The first pipeline 1 is a round tube, which is conducive to the circulation of steam in the first pipeline 1 and improves the performance of the steam pressure matcher.

[0043] Optionally, when the inlet 11 and the outlet 12 of the first flow channel 17 are respectively connected to the transmission pipeline, they can be connected through flanges.

[0044] In some embodiments, the compressor 2 further includes a second rotating shaft 24, one end of the impeller 21 is connected to the first rotating shaft 22 via the second rotating shaft 24, and the other end of the impeller 21 is connected to the adjusting disk 71, which is sleeved on the first rotating shaft.

[0045] Specifically, one end of the second rotating shaft 24 is connected to the impeller 21 , and the other end of the second rotating shaft 24 is connected to the first rotating shaft 22 . The rotation of the first rotating shaft 22 drives the second rotating shaft 24 to rotate, and the rotation of the second rotating shaft 24 drives the impeller 21 to rotate.

[0046] Optionally, the second rotating shaft 24 allows the impeller 21 to rotate in the direction of the second rotating shaft, one end of the impeller 21 is connected to the second rotating shaft 24, and the other end of the impeller 21 is connected to the adjusting disk 71. The position of the impeller 21 in the adjusting disk is adjusted by rotating in the direction of the second rotating shaft 24, so that the impeller 21 can be parallel to the first rotating shaft 22 or have an angle with the first rotating shaft 22.

[0047] In some embodiments, an adjustment groove 711 is opened on the adjustment disk 71, and the adjustment groove 711 is arranged one-to-one with the impeller 21. The adjustment component 7 also includes a first positioning member 72, and the first positioning member 72 is located in the adjustment groove 711. A plurality of second positioning members 221 are provided on the first rotating shaft 22. The first positioning member 72 cooperates with one of the second positioning members 221 to adjust the position of the impeller 21 in the adjustment groove 711.

[0048] Optionally, the impeller 21 is connected to the first rotating shaft 22 through the second rotating shaft 24, that is, the left end is the second rotating shaft 24, and the impeller can rotate along the second rotating shaft 24 to change the angle between the surface of the impeller 21 and the first rotating shaft 22. The right end is a free end connected to the adjustment disk 71. It is sleeved on the first rotating shaft 22, and the adjustment grooves 711 and the first positioning member 72 are distributed along the circumference. Each adjustment groove 711 corresponds to a blade of the impeller 21, which is used to adjust the angle between the impeller of the impeller 21 and the first rotating shaft 22. The first positioning member 72 can cooperate with the second positioning member 221 on the first rotating shaft 22 to fix the adjustment disk, thereby fixing the position of the impeller 21 on the adjustment disk.

[0049] For example, the adjustment disk is in the shape of a disk.

[0050] For example, the first positioning member 72 is a positioning pin, and the second positioning member is a positioning hole opened on the first rotating shaft. When the positioning pin is inserted into a pin hole, the position of the entire adjustment disk 71 is fixed, and the adjustment slot 711 and the impeller 21 are in a fixed position. At this time, the impeller 21 will be fixed at a specific angle.

[0051] Optionally, when the compressor 2 needs to be used to increase the intake pressure, the adjustment disk 71 on the adjustment assembly 7 is rotated, the pin in A is docked with the pin hole C, and the impeller 21 is adjusted and fixed to the working angle. At this time, the impeller 21 and the first rotating shaft 22 of the compressor 2 have a certain angle, and the air can be compressed by rotation.

[0052] Optionally, when the compressor 2 is not needed, the adjustment disk 71 on the adjustment assembly 7 is rotated, the pin in A is docked with the pin hole B, and the impeller 21 is adjusted to an angle parallel to the first rotating shaft 22. At this time, there is no interaction between the blade surface of the impeller 21 and the steam, and the blades will not compress the steam or hinder the flow of the steam.

[0053] In some embodiments, the steam pressure matcher further includes a driver 23 connected to the first rotating shaft 22 , and the energy supply assembly 3 includes an energy storage component 31 connected to the driver 23 so that the driver 23 drives the first rotating shaft 22 to rotate.

[0054] Specifically, the driver 23 is connected to the energy storage component 31, and the energy storage component 31 provides power for the driver 23, so that the driver 23 can drive the first rotating shaft 22 to rotate, and the rotation of the first rotating shaft 22 can drive the rotation of the impeller 21 connected to the first rotating shaft 22, and the rotation of the impeller 21 can pressurize the low-pressure steam.

[0055] Optionally, the energy storage element 31 is used to provide power to the driver 23 to avoid energy loss in the steam pressure matcher, so as to obtain medium-pressure steam with a higher pressure and improve the pressurization effect of the steam pressure matcher.

[0056] Optionally, the energy storage component 31 can be arranged in the first pipeline 1 to facilitate the connection between the energy storage component 31 and the driver 23. When the volume of the energy storage component 31 is large, the energy storage component 31 can also be arranged outside the first pipeline 1 to increase the energy storage capacity of the energy storage component 31 and ensure the power supply of the energy storage component 31 to the driver 23.

[0057] For example, the driver 23 can be directly connected to the first rotating shaft 22 to ensure the stability of the connection, or the driver 23 can be set as a controllable and adjustable device with a servo motor installed. By using an NI control board and LabView to write a control program, the computer can be used to monitor and condition the motor's speed, torque and other parameters, thereby adjusting the boost intensity and effect of the compressor 2 and improving the flexibility and adaptability of the compressor 2.

[0058] In some embodiments, the energy supply component 3 further includes a photovoltaic component 32 . The photovoltaic component 32 is disposed outside the first pipeline 1 . The photovoltaic component 32 is connected to the energy storage component 31 to provide electrical energy to the energy storage component 31 .

[0059] Specifically, the photovoltaic component 32 can be a photovoltaic panel. The photovoltaic panel can convert solar energy into electrical energy and output it in the form of direct current. By connecting the photovoltaic component 32 with the energy storage component 31, the electrical energy converted by the photovoltaic panel can be stored in the energy storage component 31 to charge the energy storage component 31. By adopting clean energy, the cost of pressurizing low-pressure steam can be reduced.

[0060] Optionally, when there is sufficient sunlight, the energy storage component 31 can be charged by the photovoltaic component 32. When there is insufficient sunlight, the energy stored in the energy storage component 31 can be used to stably and continuously power the compressor 2 to ensure the normal operation of the compressor 2.

[0061] For example, the photovoltaic component 32 can also be replaced with wind power generation or other power supply methods to provide electrical energy to the energy storage component 31. By setting up the compressor 2, the structure is simple, and the setting of the photovoltaic component 32 can reduce the pressurization cost.

[0062] It is understandable that the energy storage component 31 can also participate in the peak load and frequency regulation of the power plant.

[0063] For example, the energy storage component 31 is a battery.

[0064] In some embodiments, the steam pressure matcher further includes a second pipe 4 , wherein the second pipe 4 has a second flow channel 41 , the second pipe 4 at least partially extends into the first pipe 1 , and the second flow channel 41 is in communication with the first flow channel 17 .

[0065] Specifically, high-pressure steam flows in the second pipe 4 , and part of the second pipe 4 extends into the first pipe 1 , thereby improving the ability of the high-pressure steam in the second flow channel 41 to eject the low-pressure steam in the first flow channel 17 when the high-pressure steam in the second flow channel 41 enters the first flow channel 17 .

[0066] Optionally, the inlet of the second pipeline 4 is circular, and the inlet of the second pipeline 4 is perpendicular to the first pipeline 1, so as to facilitate connection and transmission with a high-pressure steam source.

[0067] Optionally, the compressor 2 performs a certain pressurization treatment on the low-pressure steam, and the pressure of the medium-pressure steam after the high-pressure steam and the pressurized low-pressure steam is greater than the medium-pressure steam after the high-pressure steam and the unpressurized low-pressure steam are mixed, that is, when the low-pressure steam is pressurized, a higher medium-pressure steam pressure can be obtained. Since the compressor 2 pressurizes the low-pressure steam by the rotation of the impeller 21, that is, by the mechanical rotation of the impeller 21, compared with the method of heating the low-pressure steam in the related art, there is no need to use the method of burning fossil energy for heating to increase the low-pressure steam input pressure, and the pressurization cost is saved under the same pressurization effect.

[0068] In some embodiments, the flow channel area of ​​the second flow channel 41 gradually decreases in the direction approaching the outlet 12 along the length direction of the first pipe 1 .

[0069] Specifically, the flow area of ​​the second flow channel 41 gradually decreases from left to right, so that a conical flow channel is formed at the connection between the second flow channel 41 and the first flow channel, which can effectively reduce the resistance drop.

[0070] In some embodiments, the first pipe 1 includes a first pipe segment 13, a second pipe segment 14, a third pipe segment 15 and a fourth pipe segment 16 which are connected in sequence, the flow area of ​​the first pipe segment 13 gradually decreases along the direction close to the outlet 12 in the length direction of the first pipe 1, the flow area of ​​the third pipe segment 15 gradually decreases along the direction close to the outlet 12 in the length direction of the first pipe 1, and the flow area of ​​the fourth pipe segment 16 gradually increases along the direction close to the outlet 12 in the length direction of the first pipe 1.

[0071] Specifically, the compressor 2 is located in the first pipe section 13, and the compressor 2 compresses and pressurizes the low-pressure steam in the first pipe section 13. The multiple impellers 21 pressurize the low-pressure steam in the first pipe section 13 layer by layer, and the flow area of ​​the first pipe section 13 is set to a shape that gradually decreases from left to right. This can not only adapt to the shape in which the dimensions of the multiple impellers 21 in the radial direction of the first rotating shaft 22 gradually decrease from left to right, but also improve the layer-by-layer pressurization effect of the impeller 21, thereby improving the pressurization effect of the compressor 2.

[0072] Specifically, the second pipe 4 extends into the second pipe section 14, and the connection point between the second flow channel 41 and the first flow channel 17 is located in the third pipe section 15. The flow cross-sectional area of ​​the third pipe section 15 gradually decreases from left to right, forming a tapered shape, which can make the high-pressure steam in the second pipe 4 enter the third pipe and drive the low-pressure steam in the first pipe section 13 and the second pipe section 14 to enter the third pipe section 15 more smoothly, effectively reducing the resistance drop, thereby improving the pressurization effect of the steam pressure matcher.

[0073] like Figure 2 As shown, the pressure of the low-pressure steam in the first pipe section 13 is set to P1, and the pressure of the high-pressure steam in the second pipe 4 is set to P0. When the high-pressure steam passes through the third pipe section 15, a negative pressure is formed at the third pipe section 15, and the pressure of the negative pressure is set to P2. Because P1 is greater than P2, the low-pressure steam in the first pipe section 13 and the second pipe section 14 enters the third pipe section 15 under the action of the negative pressure, and the high-pressure steam and the low-pressure steam are mixed in the third pipe section 15 and the fourth pipe section 16. The pressure of the medium-pressure steam after mixing is set to P3. By arranging a compressor 2 in the first pipe section 13, the pressure of the low-pressure steam can be increased, thereby increasing the mixed medium-pressure steam, and the compressor 2 is powered by the photovoltaic module, thereby reducing the pressurization cost of the low-pressure steam.

[0074] like Figure 4 As shown, the steam pressure matcher further comprises a support frame 5 , which is disposed in the first pipeline 1 , and a first rotating shaft 22 is disposed in the support frame 5 , and the first rotating shaft 22 is rotatable relative to the support frame 5 .

[0075] Specifically, by setting the support frame 5, the compressor 2 can be fixed in the first pipeline 1, and by connecting the support frame 5 with the first rotating shaft 22, the support frame 5 fixes the position of the first rotating shaft 22, and the position of the first rotating shaft 22 is set close to the inlet 11, so that the rotation of the first rotating shaft 22 can drive the rotation of the low-pressure steam, thereby increasing the pressure of the low-pressure steam.

[0076] In some embodiments, the support frame 5 includes a supporting portion 51 and a connecting portion 52 connected to each other, the connecting portion 52 is connected to the inner wall surface of the first pipe 1 , and the first rotating shaft 22 is disposed in the supporting portion 51 .

[0077] Specifically, the support frame 5 is arranged in the first pipe section 13, and the support frame 5 is arranged on the right side of the impeller 21, and the connection part 52 of the support frame 5 is arranged on the inner wall surface of the first pipe section 13. The connection parts 52 can be set to two, three, four, or six, and the smoothness of the low-pressure steam circulation is improved under the premise of ensuring the stable support of the support frame 5.

[0078] For example, when the energy storage component 31 is disposed in the first pipe 1 , the wire 8 connecting the energy storage component 31 and the photovoltaic component 32 can pass through the inside of the support portion 51 and connect to the external photovoltaic component 32 to avoid the influence of the wire 8 during the rotation of the impeller 21 .

[0079] For example, when there are two connecting parts 52 , the two supporting parts 51 are in a cross shape, the connecting part 52 is connected to the inner wall surface of the first pipe section 13 , the connecting part of the two connecting parts 52 is the supporting part 51 , and the first rotating shaft 22 is disposed inside the supporting part 51 .

[0080] Specifically, a bearing 6 is provided at the connection between the first rotating shaft 22 and the supporting portion 51 to improve the stability of the first rotating shaft 22 .
