Description

Technical Field

[0001] This invention relates to the field of hydrogen compressor technology, specifically to a hydrogen compressor with cyclic refrigeration. Background Technology

[0002] Hydrogen compressors are commonly used and versatile equipment for compressing hydrogen. They work by changing the volume of the gas to compress and transport it. Like other gases, hydrogen can be pressurized using centrifugal compressors to meet process requirements. The type of compressor used should be determined based on the hydrogen flow rate and the required pressure. Centrifugal compressors are used for circulating hydrogen.

[0003] For example, utility model application CN202222849880.2 relates to the field of compressor technology and discloses a hydrogen compressor, including a first protective shell. This utility model effectively prevents damage to the compressor body due to accidental collisions and pipeline leaks, improving the safety of compressor use. However, prolonged use of the compressor body can lead to problems with the airtightness of the hydrogen channel connection, making hydrogen leaks difficult to handle in emergencies and posing a significant safety hazard.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a hydrogen compressor with cyclic refrigeration. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hydrogen compressor with cyclic refrigeration, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a circulating refrigeration hydrogen compressor, comprising a lower frame and a first hydrogen concentration sensor, characterized in that: a hydrogen compressor body is disposed inside the lower frame, and a protective rod is installed on the top outer surface of the lower frame; an upper frame is disposed above the lower frame, and support adjustment components for height adjustment of the upper frame are installed on both sides of the upper frame; the support adjustment components include a connecting base block, an electric push rod, and a connecting top plate; the outer surface of the connecting base block is provided with an electric push rod, and the output end of the electric push rod is installed with a connecting top plate. A second hydrogen concentration sensor is installed inside the lower frame near the outer surface of the hydrogen compressor body. A suction pipe is installed on one side of the inside of the upper frame, and a suction pump is installed at the end of the suction pipe. An inlet pipe is installed at the other end of the suction pump, and a processing frame is installed at the end of the inlet pipe. The first hydrogen concentration sensor is located at the top of the processing frame, and an adjustment assembly for treating leaked hydrogen is installed inside the processing frame. The adjustment assembly includes a filter plate frame, a guide shaft, and a connecting base plate. The connecting base plate is engaged on the bottom side of the filter plate frame, and the guide shaft is rotatably installed on the top of the connecting base plate.

[0007] Furthermore, a closed inner plate is fitted onto the outer right surface of the processing frame, and the length of the closed inner plate is less than the width of the processing frame.

[0008] Furthermore, the filter plate frame has a hollow internal structure, and six sets of filter plate frames are equidistantly distributed about the inner surface of the processing frame.

[0009] Furthermore, a connecting plate is integrally provided on one side of the outer surface of the upper frame, and the connecting plate and the upper frame form a hollow rectangular shape.

[0010] Furthermore, an isolation mesh cover is fitted onto the outer surface of the connecting plate, and the isolation mesh cover has an arc-shaped structure.

[0011] Furthermore, the upper frame has an auxiliary component for heat dissipation, which includes a guide hole, a threaded cap, and an internal post. The guide hole is slidably connected to the protective rod, and a threaded cap is threadedly installed on the outer surface of the middle part of the upper frame. An internal post is threadedly provided on the outer surface of the middle part of the upper frame near the threaded cap.

[0012] Furthermore, the built-in column has a hollow structure and is connected to the upper frame, and the threaded caps are distributed at equal distances from the inner surface of the upper frame.

[0013] Furthermore, the height and length of the lower frame and the upper frame are both greater than the length and width of the hydrogen compressor body, and the protective rods are distributed at equal intervals about the top outer surface of the lower frame.

[0014] Furthermore, a heat dissipation component for dissipating heat from the hydrogen compressor body is provided on the outer surface of one side of the bottom of the lower frame, and the heat dissipation component includes a heat dissipation frame, a mounting plate and a water pump. The heat dissipation frame has a hollow rectangular structure, and the mounting plate is fixedly installed on one side of the heat dissipation frame by screws, and the water pump is provided on the outer surface of the mounting plate.

[0015] Furthermore, the water pump is connected to the lower frame and the upper frame via a corrugated water pipe, and the heat dissipation frame is arranged parallel to the rear of the lower frame.

[0016] This invention provides a hydrogen compressor with cyclic refrigeration, which has the following beneficial effects:

[0017] 1. This circulating refrigeration hydrogen compressor, through the design of the support and adjustment components, can drive the upper frame to move up and down. The continuous up and down movement of the upper frame can accelerate the airflow at the lower frame, which facilitates heat dissipation of the hydrogen compressor body during operation and prevents the temperature from being too high, thus affecting the circulating refrigeration of the hydrogen compressor body. Furthermore, through the up and down movement of the upper frame, it can continuously move down and lock into the lower frame to seal it. This prevents hydrogen leakage from the hydrogen compressor body from being contained in the closed space formed by the lower and upper frames, thus preventing hydrogen leakage from overflowing and causing greater pollution.

[0018] 2. The hydrogen compressor of this circulating refrigeration system, through adjustments to the design of components, the pump, and the processing frame, allows hydrogen to be drawn into the interior of the processing frame, facilitating the transfer of hydrogen between the lower and upper frames and enabling maintenance of the hydrogen compressor body inside the lower frame. By adjusting the design of the inert material in the components, the hydrogen drawn into the processing frame is dispersed and absorbed, improving the absorption effect. After a period of absorption, the hydrogen concentration in the processing frame is detected by a first hydrogen concentration sensor. When the hydrogen concentration is within a safe range, the processing frame can be opened.

[0019] 3. Through the design of auxiliary components, the hydrogen compressor with circulating cooling can inject cooling water into the upper frame and then the cooling water will enter the interior column. By adjusting the position of the upper frame, the interior column can be positioned in the gap between the hydrogen compressor body and the lower frame for targeted cooling and heat dissipation.

Detailed Implementation

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention provides a technical solution: a circulating refrigeration hydrogen compressor, comprising a lower frame 1, a hydrogen compressor body 2, a protective rod 3, an upper frame 4, a connecting plate 5, an isolation mesh cover 6, a first hydrogen concentration sensor 7, a processing frame 8, a closed inner plate 9, a support and adjustment assembly 10, a connecting bottom block 1001, an electric push rod 1002, a transition top plate 1003, a second hydrogen concentration sensor 11, a heat dissipation assembly 12, a heat dissipation frame 1201, a mounting plate 1202, a water pump 1203, an auxiliary assembly 13, a guide hole 1301, a threaded cap 1302, an internal column 1303, a suction pump 14, an inlet pipe 15, a suction pipe 16, an adjustment assembly 17, a filter plate frame 1701, a guide shaft 1702, and a connecting bottom plate 1703. The lower frame 1... The interior houses a hydrogen compressor body 2, and a protective rod 3 is installed on the top outer surface of the lower frame 1. A heat dissipation component 12 for cooling the hydrogen compressor body 2 is installed on the bottom outer surface of the lower frame 1. The heat dissipation component 12 includes a heat dissipation frame 1201, a mounting plate 1202, and a water pump 1203. The heat dissipation frame 1201 has a hollow rectangular structure. The mounting plate 1202 is fixed to one side of the interior of the heat dissipation frame 1201 with screws, and the water pump 1203 is installed on the outer surface of the mounting plate 1202. The water pump 1203 is connected to the lower frame 1 and the upper frame 4 through a corrugated water pipe. The heat dissipation frame 1201 is arranged parallel to the rear of the lower frame 1. The interior of the heat dissipation frame 1201 is hollow and contains cooling water. The design of the water pump 1203 allows the cooling water in the heat dissipation frame 1201 to be cooled. Cooling water is supplied to the lower frame 1 and the upper frame 4 to facilitate water cooling from the outside of the hydrogen compressor body 2, reducing the heat generated during the operation of the hydrogen compressor body 2. The upper frame 4 is located above the lower frame 1, and support adjustment components 10 for height adjustment of the upper frame 4 are installed on both sides of the upper frame 4. The height and length of the lower frame 1 and the upper frame 4 are greater than the length and width of the hydrogen compressor body 2, and the protective rods 3 are evenly distributed about the top outer surface of the lower frame 1. The upper frame 4 has an auxiliary component 13 for auxiliary heat dissipation inside, and the auxiliary component 13 includes a guide hole 1301, a threaded cover 1302 and an internal post 1303. The inside of the guide hole 1301 is slidably connected to the protective rod 3, and the middle outer surface of the upper frame 4 is... A threaded cap 1302 is installed on the upper frame 4. An internal pillar 1303 is threaded on the outer surface of the upper frame 4 near the threaded cap 1302. The internal pillar 1303 has a hollow structure and is connected to the upper frame 4. The threaded caps 1302 are evenly distributed around the inner surface of the upper frame 4. Because of the connection between the internal pillars 1303 and the upper frame 4, cooling water can be injected into the upper frame 4 and then enter the internal pillars 1303. By adjusting the position of the upper frame 4, the internal pillars 1303 can be positioned in the gap between the hydrogen compressor body 2 and the lower frame 1 for targeted cooling. The threaded connection between the upper frame 4 and the threaded cap 1302 allows for the installation of multiple internal pillars 1303.The threaded cap 1302 can be rotated to expose the mounting holes in the upper frame 4, facilitating the installation of the built-in column 1303 at these holes. Unused mounting holes are sealed by the threaded cap 1302, allowing users to selectively install according to their needs and heat dissipation area. A connecting plate 5 is integrally formed on one side of the outer surface of the upper frame 4, creating a hollow rectangular shape with the upper frame 4. The protective rod 3 between the lower frame 1 and the upper frame 4 provides external protection for the hydrogen compressor body 2, preventing collisions with foreign objects while also providing heat dissipation. An isolation mesh cover 6 is fitted onto the outer surface of the connecting plate 5, and the isolation mesh cover 6 has an arc-shaped structure. This design ensures airflow while protecting the internal components of the isolation mesh cover 6. The protection mechanism allows for easy separation of the isolation mesh cover 6 from the connecting plate 5 during maintenance and repair of the connecting parts. The operation is simple and quick. The support and adjustment assembly 10 includes a connecting base block 1001, an electric push rod 1002, and a transition top plate 1003. The electric push rod 1002 is mounted on the outer surface of the connecting base block 1001, and the transition top plate 1003 is installed at the output end of the electric push rod 1002. The design of the connecting base block 1001 and the electric push rod 1002 allows the upper frame 4, connected to the transition top plate 1003, to move up and down. This continuous up-and-down movement of the upper frame 4 accelerates airflow at the lower frame 1, facilitating heat dissipation for the hydrogen compressor body 2 during operation and preventing excessively high temperatures from affecting the cyclic cooling of the hydrogen compressor body 2.

[0029] like Figure 1 and Figure 5 As shown, a second hydrogen concentration sensor 11 is installed inside the lower frame 1 near the outer surface of the hydrogen compressor body 2. This sensor's location within the lower frame 1 allows for timely detection of leaks in the hydrogen channel of the hydrogen compressor body 2 due to malfunctions, facilitating the user's immediate closure of the hydrogen channel valve. The design connecting the bottom block 1001 and the electric push rod 1002 enables the upper frame 4, connected to the top plate 1003, to move vertically. This allows the upper frame 4 to continuously descend and engage with the lower frame 1 for sealing, thereby improving hydrogen compression. The leaked hydrogen gas in the main body 2 is contained in the closed space formed by the lower frame 1 and the upper frame 4 to prevent the hydrogen gas from overflowing and causing greater pollution. An exhaust pipe 16 is provided on one side of the interior of the upper frame 4, and an exhaust pump 14 is installed at the end of the exhaust pipe 16. An intake pipe 15 is provided at the other end of the exhaust pump 14, and a processing frame 8 is installed at the end of the intake pipe 15. The design of the exhaust pump 14 and the exhaust pipe 16 allows the hydrogen gas sealed between the lower frame 1 and the upper frame 4 to be extracted into the interior of the processing frame 8, which facilitates the transfer of hydrogen gas between the lower frame 1 and the upper frame 4 and is beneficial for the maintenance of the hydrogen compressor main body 2 inside the lower frame 1.

[0030] like Figure 1 and Figure 6 As shown, the first hydrogen concentration sensor 7 is located at the top of the processing frame 8, and the processing frame 8 is equipped with an adjustment assembly 17 for treating leaked hydrogen. The adjustment assembly 17 includes a filter plate frame 1701, a guide shaft 1702, and a connecting base plate 1703. The connecting base plate 1703 is engaged with one side of the bottom of the filter plate frame 1701, and the guide shaft 1702 is rotatably mounted on the top of the connecting base plate 1703. The filter plate frame 1701 has a hollow internal structure, and six sets of filter plates are evenly distributed on the inner surface of the processing frame 8. A closed inner plate 9 is engaged with the outer right surface of the processing frame 8, and the length of the closed inner plate 9 is less than the width of the processing frame 8. The processing frame 8 contains useful sand, vermiculite, or... Other inert materials, when hydrogen is extracted into the processing frame 8, can be absorbed by the sand, vermiculite or other inert materials in the filter plate frame 1701, avoiding the direct emission of hydrogen to the outside and causing danger. The angle of the filter plate frame 1701 can be adjusted by the rotating connection design of the guide shaft 1702 and the connecting base plate 1703, so that the hydrogen extracted into the processing frame 8 can be dispersed and absorbed, improving the absorption effect of hydrogen. After absorption for a period of time, the hydrogen concentration in the processing frame 8 is detected by the design of the first hydrogen concentration sensor 7. When the detected hydrogen concentration is within the safe range, the closed inner plate 9 can be pulled outward to open the processing frame 8, which facilitates the replacement of the inert material inside the filter plate frame 1701 in the processing frame 8.

[0031] In summary, as Figures 1-6As shown, this circulating refrigeration hydrogen compressor, during use, utilizes a protective rod 3 between the lower frame 1 and the upper frame 4 to protect the hydrogen compressor body 2 from external impacts by foreign objects, while also providing heat dissipation. The design connecting the base block 1001 and the electric push rod 1002 allows the upper frame 4, connected to the top plate 1003, to move vertically. This continuous vertical movement of the upper frame 4 accelerates airflow at the lower frame 1, facilitating heat dissipation for the hydrogen compressor body 2 during operation and preventing overheating from affecting its circulating refrigeration. Furthermore, the hollow heat dissipation frame 1201, containing cooling water, is powered by a water pump 1203. Cooling water in 201 is supplied to the lower frame 1 and the upper frame 4, facilitating water cooling from the outside of the hydrogen compressor body 2 and reducing the heat generated during operation. The internal column 1303 is connected to the upper frame 4, allowing cooling water to enter the internal column 1303 after it is injected into the upper frame 4. Adjusting the position of the upper frame 4 allows the internal column 1303 to be positioned in the gap between the hydrogen compressor body 2 and the lower frame 1 for targeted cooling. The threaded connection between the upper frame 4 and the threaded cover 1302 allows the threaded cover 1302 to be rotated to expose the mounting holes in the upper frame 4 when multiple internal columns 1303 need to be installed, facilitating the installation of the internal columns 1303 at these holes. 3. Unused mounting holes are sealed with threaded caps 1302, allowing users to selectively install according to their needs and heat dissipation area. Furthermore, the design of the second hydrogen concentration sensor 11 located in the lower frame 1 enables timely detection of leaks in the hydrogen passage of the hydrogen compressor body 2 due to malfunctions, facilitating immediate closure of the hydrogen passage valve. The design connecting the base block 1001 and the electric push rod 1002 allows the upper frame 4, connected to the top plate 1003, to move vertically. This allows the upper frame 4 to continuously move downwards and engage with the lower frame 1, sealing any leaking hydrogen within the enclosed space formed by the lower frame 1 and the upper frame 4, preventing further leakage. To prevent further pollution, the design of the suction pump 14 and suction pipe 16 extracts hydrogen gas sealed between the lower frame 1 and the upper frame 4 into the processing frame 8. This facilitates the transfer of hydrogen gas between the lower frame 1 and the upper frame 4 and makes it easier to maintain the hydrogen compressor body 2 inside the lower frame 1. The filter plate frame 1701 is hollow and contains sand, vermiculite, or other inert materials. When hydrogen gas is extracted into the processing frame 8, it can be absorbed by the sand, vermiculite, or other inert materials in the filter plate frame 1701, preventing the direct emission of hydrogen gas to the outside and causing danger. The rotatable connection design of the guide shaft 1702 and the connecting base plate 1703 allows for angle adjustment of the filter plate frame 1701, enabling the hydrogen gas extracted into the processing frame 8 to be dispersed and absorbed, thus improving the absorption effect of hydrogen gas.After a period of absorption, the hydrogen concentration in the processing frame 8 is detected by the first hydrogen concentration sensor 7. When the detected hydrogen concentration is within a safe range, the inner closed plate 9 can be pulled outward to open the processing frame 8, facilitating the replacement of the inert material inside the filter plate frame 1701 in the processing frame 8.
