Abstract
Description
Technical Field
[0001] This application relates to the field of steam compressor technology, and more specifically, to a steam compressor inlet parameter adjustment device. Background Technology
[0002] Steam compressors are key equipment for heat recovery, waste heat utilization, and industrial process pressurization. They play an important role in fields such as power, chemical, petroleum, metallurgy, and new energy. Their core function is to increase the pressure and temperature of steam through mechanical compression, thereby achieving efficient energy recovery and reuse, reducing system energy consumption and carbon emissions.
[0003] In actual operation, the inlet parameters of the steam compressor, such as pressure, temperature and distortion index, are easily affected by factors such as ambient temperature, latitude and altitude, upstream conditions, pipeline blockage or layout, cooling system conditions and inlet spray conditions. This can cause the inlet parameters to deviate from the optimal operating conditions, reduce operating efficiency, induce unstable phenomena such as surge and stall, and seriously threaten equipment safety.
[0004] In the process of setting up an experimental platform to study the impact of inlet parameters on the performance of a centrifugal steam compressor, it is necessary to design and use an inlet parameter adjustment device to simulate the uneven distribution of inlet pressure of the steam compressor under actual operating conditions. This is of great significance for improving the operating efficiency, stability, and adaptability of the compressor system. Existing steam compressor inlet parameter adjustment devices can only realize experiments under a single operating condition. To achieve parameter adjustment under different operating conditions (such as different pressures or temperatures), it is usually necessary to replace the adjustment device. This process often requires disassembling the original adjustment device from the experimental system, installing an adjustment device suitable for the new operating conditions, and reassembling and calibrating it. The steps are cumbersome, time-consuming, and labor-intensive. Summary of the Invention
[0005] In view of this, the purpose of this application is to provide a steam compressor inlet parameter regulating device to improve the situation of existing regulating devices with a single regulating condition and realize parameter adjustment under multiple conditions.
[0006] To achieve the above objectives, this application provides the following technical solution:

[0008] The adjustment component is disposed between the first pipe section and the second pipe section. The adjustment component includes multiple pressure adjustment modules, each of which includes a baffle. The adjustment component has a locked state and an unlocked state.

When the adjustment component is in the locked state, any two adjacent pressure adjustment modules are relatively fixed.

[0010] Optionally, in the above-mentioned steam compressor inlet parameter regulating device, the first baffle is configured to allow some gas to pass through or to block gas from passing through; and / or, the second baffle is configured to allow some gas to pass through or to block gas from passing through.
[0011] Optionally, in the above-mentioned steam compressor inlet parameter adjustment device, for any two adjacent pressure adjustment modules, one is provided with a groove extending circumferentially along the first base, and the other is provided with a boss that mates with the groove.
[0012] Optionally, in the above-mentioned steam compressor inlet parameter adjustment device, the first base is provided with an installation notch for installing the baffle. At the location of the installation notch, one end of the first base and the baffle are respectively provided with a snap-fit part, and the other end is respectively provided with a snap-fit groove that cooperates with the snap-fit part.
[0013] Optionally, in the above-mentioned steam compressor inlet parameter adjustment device, each of the pressure adjustment modules is connected to the first pipe section and the second pipe section respectively through a locking assembly.
[0014] Optionally, in the above-mentioned steam compressor inlet parameter regulating device, the regulating component further includes a temperature regulating module. The temperature regulating module includes a second base and a temperature regulating plate. The temperature regulating plate includes a regulating plate body and a heating element. The heating element is disposed on the regulating plate body and includes multiple parallel conductive branches.
[0015] Optionally, in the above-mentioned steam compressor inlet parameter regulating device, the multiple conductive branches are formed by multiple heating wires arranged in parallel, and the temperature regulating plate is provided with multiple crossbeams, with the heating wires wound around the crossbeams.

Moreover, this device does not require disassembling the pressure regulating module. It is only necessary to keep the regulating component in the unlocked state and rotate the corresponding pressure regulating module, which reduces frequent disassembly and assembly, simplifies the steps, saves manpower and resources, and reduces experimental costs.

Detailed Implementation
[0037] The core of this application is to disclose a steam compressor inlet parameter adjustment device to improve the situation of existing adjustment devices with a single adjustment condition and realize parameter adjustment under multiple conditions.
[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0039] like Figure 1 As shown in the illustration, this application discloses an inlet parameter regulating device for a steam compressor, which is installed at the inlet of the steam compressor to regulate the inlet parameters of the steam compressor. Specifically, the steam compressor inlet parameter regulating device includes a pipe assembly 100 and an regulating component 200. Along the gas flow direction, the pipe assembly 100 includes a first pipe section 110 and a second pipe section 120, which are detachably connected. The regulating component 200 is disposed between the first pipe section 110 and the second pipe section 120.
[0040] like Figure 1 and Figure 2 As shown, the regulating assembly 200 includes multiple pressure regulating modules 210, each of which includes a baffle 212. The baffle 212 obstructs the flow of gas in the pipeline assembly 100 to change the gas pressure.
[0041] The regulating component 200 includes a locked state and an unlocked state. When the regulating component 200 is in the unlocked state, any two adjacent pressure regulating modules 210 can rotate relative to each other. By rotating any one of the pressure regulating modules 210, the position of the baffle 212 set on that pressure regulating module 210 is changed, thereby changing the area of obstruction to the gas and thus changing the gas pressure. When the regulating component 200 is in the locked state, any two adjacent pressure regulating modules 210 are relatively fixed, and experiments can be conducted under any operating condition.
[0042] In actual use, the adjustment component 200 is unlocked, and by rotating the corresponding pressure adjustment module 210, the baffle 212 on different pressure adjustment modules 210 can be in different positions to change the blocking area of the gas, thereby realizing the adjustment of experimental parameters under different pressure conditions. After the adjustment is completed, the adjustment component 200 is locked and the experiment can be carried out.
[0043] The steam compressor inlet parameter adjustment device disclosed in this application includes an adjustment component 200 with a locked state and an unlocked state. When different pressure conditions need to be tested, the adjustment component 200 is in the unlocked state. By rotating the pressure adjustment module 210, the position of the baffle 212 is changed, thereby changing the gas blocking area. Then, locking the adjustment component 200 allows for testing under the corresponding conditions. This improves upon the single-condition adjustment of existing adjustment devices, enabling parameter adjustment under multiple conditions and improving experimental efficiency. Furthermore, this device does not require disassembling the pressure adjustment module 210; simply keeping the adjustment component 200 in the unlocked state and rotating the corresponding pressure adjustment module 210 reduces frequent disassembly and assembly, simplifies the process, saves manpower and resources, and lowers experimental costs.
[0044] In some specific embodiments, such as Figure 2 As shown, the pressure regulating module 210 includes a first base 211 and a baffle 212, as... Figures 4-6 As shown, the baffle 212 includes a connecting portion 2121 and a baffle body 2122. The connecting portion 2121 is connected to the first base 211, and the baffle body 2122 is connected to the connecting portion 2121. The baffle body 2122 includes at least one of a first baffle portion 21221 and a second baffle portion 21222. The first baffle portion 21221 extends circumferentially along the first base 211, and the second baffle portion 21222 extends radially along the first base 211. Figure 5 and Figure 6 The first baffle portion 21221 shown is an arc-shaped structure extending circumferentially along the first base 211. Figure 4 The second baffle portion 21222 shown is a fan-shaped structure extending radially along the first base 211. It should be noted that in some other embodiments, the baffle body 2122 can be a combination of the first baffle portion 21221 and the second baffle portion 21222. The above-described arrangement of the baffle body 2122 supports multi-module combined testing and allows for free combination of circumferential and radial distortions.
[0045] The first baffle section 21221 can change the circumferential area of the intake section, and the second baffle section 21222 can change the radial area of the intake end, thereby achieving multi-angle and multi-type inlet pressure regulation of the intake. The connecting part 2121 and the baffle body 2122 can be an integral structure or a separate structure. If it is a separate structure, the baffle body 2122 can be replaced without replacing the connecting part 2121; the integral structure can improve the structural strength of the baffle 212. The specific structure can be determined according to actual needs.
[0046] In some specific embodiments, for each pressure regulating module 210, there are one or more baffles 212. When there are multiple baffles 212, each baffle 212 is arranged at circumferential intervals along the first base 211. Figure 2 The pressure regulating module 210 shown in the figure has one baffle 212. The figure is only an example, and the specific number of baffles 212 can be set according to the actual situation.
[0047] In some specific embodiments, the first baffle portion 21221 is configured to allow some gas to pass through or to block gas from passing through; and / or, the second baffle portion 21222 is configured to allow some gas to pass through or to block gas from passing through. Specifically, when the first baffle portion 21221 blocks gas from passing through, it can be a plate-like structure; when it allows some gas to pass through, the first baffle portion 21221 has a perforated structure. The perforated structure allows the first baffle portion 21221 to be a grid structure or a mesh structure, or a partially plate-like structure with a perforated structure. The structure of the second baffle portion 21222 is the same as that of the first baffle portion 21221, and will not be described again. Figure 4 The second baffle portion 21222 shown in the figure has a mesh structure. Figure 5 The first baffle portion 21221 shown in the figure has a mesh structure. Figure 6 The first baffle part 21221 shown is a plate-shaped structure. Only a few examples are given in the figure. The specific structure can be adapted to meet actual needs.
[0048] In some specific embodiments, for any two adjacent pressure regulating modules 210, in order to guide the rotation of either pressure regulating module 210, one of them is provided with a groove 2111 extending circumferentially along the first base 211. The groove 2111 is preferably a complete annular groove, so that the pressure regulating module 210 can rotate at any angle circumferentially. The other is provided with a boss 2112 that mates with the groove 2111. Specifically, as shown... Figures 1-3 As shown. Furthermore, corresponding grooves 2111 are provided on the connection surfaces of the first pipe section 110 and the second pipe section 120 with the pressure regulating module 210, and corresponding bosses 2112 are provided on the pressure regulating module 210 that cooperates with the first pipe section 110 and the second pipe section 120. The grooves 2111 and bosses 2112 serve not only as guides but also as positioning elements, and simultaneously provide a self-sealing function, reducing leakage problems inherent in traditional connection methods.
[0049] In some specific embodiments, such as Figure 3As shown, the first base 211 is provided with an installation notch 2113 for mounting the baffle 212. The installation notch 2113 makes the first base 211 have a C-shaped structure. At the installation notch 2113, one of the first base 211 and the baffle 212 is provided with a snap-fit part at both ends, and the other is provided with a snap-fit groove that mates with the snap-fit part at both ends. Figure 3 The first base 211 shown in the figure has a first latching portion 2114 and a second latching portion 2115 respectively provided at both ends, as shown in the figure. Figure 4 As shown, the baffle 212 has snap-fit grooves at both ends that mate with the first snap-fit portion 2114 and the second snap-fit portion 2115, respectively. The first base 211 can be made of an elastic material, and its elastic deformation connects it to the baffle 212; alternatively, to ensure the secure connection between the baffle 212 and the first base 211, fasteners can be used to secure them together. In some specific embodiments, the pressure regulating module 210 is preferably made of stainless steel.
[0050] In some specific embodiments, each pressure regulating module 210 is connected to the first pipe section 110 and the second pipe section 120 respectively via a locking assembly. Specifically, the locking assembly may include a disc flange, bolts, and nuts, such as... Figures 7-8 As shown, a first disc flange 1101 is provided at the end of the first pipe section 110 connected to the pressure regulating module 210, and a second disc flange 1201 is provided at the end of the second pipe section 120 connected to the pressure regulating module 210. A set of through holes are evenly distributed along the circumference of each pressure regulating module 210. The first pipe section 110, each pressure regulating module 210, and the second pipe section 120 are connected sequentially by bolts and nuts. When it is necessary to adjust the inlet parameters of the steam compressor, the bolts and nuts are removed, the pressure regulating module 210 is rotated, and when it is rotated to the appropriate position, the pressure regulating module 210 is locked by the bolts and nuts. There is no need to disassemble the entire device, reducing the tediousness of frequent disassembly and assembly. In some other specific embodiments, the locking component can also be a clamp.
[0051] In some specific embodiments, the regulating component 200 further includes a temperature regulating module, such as... Figure 10 As shown, the temperature regulation module includes a second base and a temperature regulation plate 221. The temperature regulation plate 221 includes a plate body 2211 and a heating element 2212. The heating element 2212 is disposed on the plate body 2211 and includes multiple parallel conductive branches. Specifically, the multiple conductive branches are composed of multiple parallel heating wires. Figure 10As shown, the temperature regulating plate 221 is provided with multiple crossbeams 2213, which can be straight beams or curved beams. The heating wire is preferably made of nickel-chromium heating alloy, which has high temperature resistance and oxidation resistance. The second base and the regulating plate body 2211 are preferably made of stainless steel.
[0052] On the one hand, the setting of multiple parallel conductive branches can achieve different heating powers by controlling the on / off state of different conductive branches, thereby heating the water vapor entering the pipe assembly 100 to different temperatures; on the other hand, the setting of multiple parallel conductive branches can prevent the failure of the entire temperature regulation module due to the breakage of a certain conductive branch.
[0053] The number of temperature regulation modules can be one, two, or more. Preferably, the structure of the second base is the same as that of the first base 211. The second base is provided with a mounting notch 2113 for mounting the temperature regulation plate 221. The second base has an overall C-shaped structure, and both ends of the second base are provided with snap-fit parts. The structure of the temperature regulation plate 221 is preferably fan-shaped, and both ends of the temperature regulation plate 221 are provided with snap-fit grooves that cooperate with the snap-fit parts. The structure of the second base is the same as that of the first base 211, which is versatile. Both the first base 211 and the second base can be used as bases for the pressure regulation module 210 and the temperature regulation module, enabling quick replacement of the pressure regulation module 210 and the temperature regulation module.
[0054] Specifically, each heating wire is connected to a controller, and its power can be adjusted by setting a preset temperature value. To prevent the heating wire from breaking due to direct airflow impact, the pipe assembly 100 is equipped with temperature and flow detection elements, both connected to the controller. The controller inputs the preset temperature value, a safe temperature threshold, and a safe flow threshold. If the actual gas temperature and flow rate exceed the safe threshold, the heating wire stops working; if the actual gas flow rate is within the safe flow threshold range but the actual gas temperature exceeds the preset temperature value, the heating wire power is reduced; if the actual gas temperature is lower than the preset temperature value, the heating wire power is increased. This real-time adjustment logic automatically cuts off the circuit to prevent dry burning and overheating, ensuring experimental safety. Furthermore, the heating wires are preferably high-temperature resistant and steam-proof wires, and a pneumatic connector is installed at the wire trough outlet to prevent water vapor from damaging the experimental equipment and causing leaks.
[0055] When the steam compressor inlet parameter regulating device includes both a pressure regulating module 210 and a temperature regulating module, the temperature regulating module is preferably located downstream of the pressure regulating module 210 along the gas flow direction. The simultaneous installation of the pressure regulating module 210 and the temperature regulating module allows for simultaneous regulation of both gas pressure and temperature, enabling temperature-pressure composite distortion experiments, comprehensive testing under multi-parameter coupling conditions, and meeting the requirements of variable operating condition experiments, thus possessing the capability to simulate complex operating conditions.
[0056] In some specific embodiments, the baffle 212 is detachably or non-detachably connected to the first base 211; and / or, the temperature regulating plate 221 is detachably or non-detachably connected to the second base. Detachable connection methods include, but are not limited to, bolted connection and snap-fit connection, while non-detachable connection methods include, but are not limited to, welded connection and adhesive connection. The specific connection method can be further selected according to actual needs.
[0057] like Figure 1 , Figure 8 and Figure 9 As shown, in some specific embodiments, the second pipe section 120 includes a first pipe section portion 121 and a second pipe section portion 122. The second pipe section portion 122 is disposed within the first pipe section portion 121. The first pipe section portion 121 and the second pipe section portion 122 are detachably connected. Preferably, the first pipe section portion 121 and the second pipe section portion 122 are connected by a connecting clamp 130, and the length of the second pipe section 120 can be adjusted according to actual needs. Under different operating conditions, the number of pressure regulating modules 210 and temperature regulating modules installed is different, and therefore the required gap between the first pipe section 110 and the second pipe section 120 is different. The length of the second pipe section 120 can be flexibly adjusted according to actual installation needs to adjust the gap between the first pipe section 110 and the second pipe section 120.
[0058] To verify the regulating performance of the pressure regulating module 210 and the temperature regulating module, a simulation model of the steam compressor inlet parameter regulating device was established using finite element analysis (CFD) software. The model parameters were set as follows: inlet flow velocity of 80 m / s, temperature of 124℃ (397.5 K), and outlet back pressure of 150 kPa. The figure shows the pressure and temperature contour maps of the steam compressor inlet. Figure 11 This is a pressure cloud diagram within the pipe assembly 100 without the pressure regulating module 210 installed. Figure 12 This is a temperature cloud map of the pipe assembly 100 without the temperature control module installed. Figure 13 The diagram shows the addition of a pressure regulating module 210, and the baffle body 2122 of the pressure regulating module 210 includes a first baffle portion 21221, which is a pressure cloud diagram with a 60° circumferential mesh structure. Figure 14The diagram shows a pressure cloud map of a device with a pressure regulating module 210 installed, wherein the baffle body 2122 of the pressure regulating module 210 includes a first baffle portion 21221, and the first baffle portion 21221 is a 60° circumferential plate-like structure. Figure 13 and Figure 14 It can be seen that after the pressure regulating module 210 is installed, the inlet pressure distribution of the steam compressor is uneven, indicating that the pressure regulating module 210 can play a good regulating role. Figure 15 The image shows the addition of a 60° temperature regulating plate 221, with a power setting of 50000W / m. 2 The subsequent simulation results show that the inlet temperature distribution of the steam compressor is non-uniform, indicating that the device can effectively regulate the gas temperature and meet the experimental requirements. It should be noted that the degree value of the first baffle section 21221 refers to the degree value of the central angle.
[0059] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
