Description

Technical Field

[0001] This invention relates to the field of waste heat recovery technology, and in particular to a waste heat recovery and reuse device for pressure vessels. Background Technology

[0002] A pressure vessel is a sealed device used to hold gases or liquids and withstand a certain pressure. It is widely used in industry, energy, chemical industry, scientific research, and civilian applications. Its core characteristic is that strict standards in design, manufacturing, and use ensure safe operation under complex conditions such as high pressure, high temperature, or low temperature.

[0003] The announcement number CN109737786B discloses a waste heat recovery and reuse system for large pressure vessels. This system utilizes phase change heat storage for recovery and employs an inlet preheating component to preheat the air entering the pressure vessel, improving preheating efficiency. In waste heat recovery, the system first uses phase change heat storage. After the phase change heat storage component completes its heat recovery, the inlet preheating component is activated to recover the hot air entering the vessel. If sufficient waste heat remains, a water circulation waste heat recovery component can be activated for hot water circulation heat recovery, further improving recovery efficiency. The connecting thin tube of the inlet preheating component has an inner diameter smaller than that of the heat exchange tube. Adjacent heat exchange tubes are connected by connecting thin tubes, which improves the uniformity of airflow mixing within the heat exchange tubes, ensuring heat exchange efficiency. Additionally, spiral grooves are provided on the outer wall of the heat exchange tubes to increase the heat exchange area.

[0004] Pressure vessels still have some problems in actual use. Currently, industrial waste heat recovery relies on pipeline heat exchange as its core technology. This involves adding jacketed or sleeved heat exchange pipelines outside the pressure vessel and utilizing the circulating flow of heat transfer media (such as water or heat transfer oil) to absorb waste heat conducted from the pressure vessel wall. However, pipeline heat exchange systems lack flexible control capabilities, resulting in unstable waste heat recovery and difficulty in meeting downstream energy demands. Furthermore, the pipeline layout is limited by the pressure vessel structure, limiting the heat exchange area and leading to low waste heat recovery efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a pressure vessel waste heat recovery and reuse device, which realizes the increase of the heat-receiving area by attaching the arc plate on the conduction component to the surface of the pressure vessel body, and then recovers and reuses the heat generated by the pressure vessel body through the cooperation of the flow-stopping component and the recovery component.

[0015] In summary, the present invention has the following beneficial effects: 1. The present invention has a reasonable structure. Liquid enters the interior of the cavity through the inlet pipe. The heat generated by the pressure vessel body is conducted to the liquid inside the cavity through the arc plate, and then conducted out through the outlet pipe. When installing the arc plate, the arc plate is attached to the surface of the pressure vessel body, and then the arm plate is rotated to move the sleeve block on the docking rod. The insertion rod on the sleeve block is pulled to move the insertion block to one side of the locking block. Then the insertion rod is released, and the insertion block is locked on the locking block by the elastic force of the first spring, thereby completing the installation of the arc plate.

[0016] 2. In this invention, the heated liquid inside the cavity enters the liquid passage pipe through the liquid outlet pipe. Then, the liquid passage pipe carries the heated liquid through the bend pipe into the horizontal pipe. When the piston moves, a negative pressure is generated inside the horizontal pipe and the bend pipe. Then, the horizontal pipe moves downward, and the liquid inside the bend pipe enters the horizontal pipe. The horizontal pipe is controlled by the elastic force of the second spring to prevent the liquid inside the bend pipe from flowing back.

[0017] 3. In this invention, the operation of the servo motor causes the rotating rod to rotate. The rotation of the rotating rod causes the linkage plate to pull the bracket on the crossbar to move, which facilitates the connecting plate on the bracket to drive the pull rod to move. This facilitates the pull rod to drive the piston inside the cylinder to move, thereby extracting the liquid inside the horizontal tube. When the piston retracts, the horizontal tube is in a closed state, and the liquid inside the horizontal tube pushes the cover plate, which facilitates the discharge of the liquid inside the horizontal tube, making it convenient for the next liquid extraction operation.

[0024] In one embodiment of this invention, the conductive assembly includes a pair of arc-shaped plates 2 attached to the surface of the pressure vessel body 1.

An inlet pipe 202 is fixedly connected to the middle of the surface of each pair of arc-shaped plates 2. An outlet pipe 203 is fixedly connected to the bottom surface of each pair of arc-shaped plates 2. A hinge seat 204 is fixedly connected to the top of the surface of one of the arc-shaped plates 2. A pair of arm plates 205 are rotatably connected to the hinge seat 204. The other ends of each pair of arm plates 205 are rotatably connected to the other. A connecting rod 206 is connected to a sleeve block 207 at its middle position. A connecting rod 208 is movably inserted into the sleeve block 207. A collar 209 is fixedly connected to one end of the connecting rod 208. A first spring 210 is sleeved on the connecting rod 208. The two ends of the first spring 210 are fixedly connected to one side of the collar 209 and one side of the sleeve block 207, respectively. A connecting block 211 is fixedly connected to the other end of the connecting rod 208. The connecting block 211 is locked onto a locking block 212. The locking block 212 is fixedly installed on the surface of another arc-shaped plate 2.

[0025] Specifically, the liquid enters the cavity 201 through the inlet pipe 202. The heat generated by the pressure vessel body 1 is conducted to the liquid inside the cavity 201 through the arc plate 2, and then conducted out through the outlet pipe 203. When installing the arc plate 2, the arc plate 2 is attached to the surface of the pressure vessel body 1, and then the arm plate 205 is rotated to move the sleeve block 207 on the docking rod 206. The insertion rod 208 on the sleeve block 207 is pulled to move the insertion block 211 to one side of the locking block 212. Then the insertion rod 208 is released, and the insertion block 211 is locked onto the locking block 212 by the elastic force of the first spring 210, thereby completing the installation of the arc plate 2.

[0026] In one embodiment of this invention, the flow-stopping assembly includes a liquid-passing pipe 3 detachably connected to the liquid outlet pipe 203. The other end of the liquid-passing pipe 3 extends to the top surface of the collection tank 104. A bend 301 is fixedly connected to the bottom of the middle section of the liquid-passing pipe 3, extending into the interior of the collection tank 104. A horizontal pipe 303 with openings at both ends is fixedly connected to the bottom end of the bend 301. Several sets of cylindrical tubes 304 are fixedly connected laterally to the surface of the horizontal pipes 303, and several openings are formed on the cylindrical tubes 304. A ball tube 306 is provided on the round hole 305 and the bend 301. A stopper rod 307 is provided inside the ball tube 306. The top end of the stopper rod 307 extends through the bend 301 to the top position of the horizontal plate 308. The two ends of the horizontal plate 308 are fixedly connected to the inner wall of the collection box 104. A retaining ring 309 is fixedly connected to the top position of the stopper rod 307. A second spring 310 is sleeved on the stopper rod 307. The two ends of the second spring 310 are respectively in contact with the bottom surface of the retaining ring 309 and the top surface of the horizontal plate 308.

[0027] Specifically, the heated liquid inside the cavity 201 enters the liquid passage pipe 3 through the liquid outlet pipe 203. Then, the liquid passage pipe 3 guides the heated liquid through the bend pipe 301 into the horizontal pipe 303. When the piston 405 moves, a negative pressure is generated inside the horizontal pipe 303 and the bend pipe 301. Then, the horizontal pipe 303 moves downward, and the liquid inside the bend pipe 301 enters the horizontal pipe 303. The second spring 310 controls the horizontal pipe 303 to prevent the liquid inside the bend pipe 301 from flowing back.

[0028] In one embodiment of this invention, the recycling assembly includes rings 4 fixedly installed at both ends of a horizontal tube 303. A pair of limiting rods 401 are fixedly connected to the rings 4. A docking plate 402 is fixedly connected between the other ends of the pair of limiting rods 401. A third spring 403 is fixedly connected to the middle of the inner wall of the docking plate 402. The other end of the third spring 403 is fixedly connected to a cover plate 404. The cover plate 404 is attached to one end of the horizontal tube 303. The upper and lower sides of the cover plate 404 are slidably connected to the pair of limiting rods 401. A piston 405 is provided inside the cylinder 304. The piston 405 is fixedly connected to a pull rod 406. One end of the pull rod 406 extends to the outside of the cylinder 304 and is fixedly connected to the connecting plate 407. A pair of brackets 408 are fixedly connected to the connecting plate 407. A crossbar 409 is rotatably connected between the top ends of the pair of brackets 408. A rotating rod 410 is rotatably connected to the transverse position inside the collection box 104. One end of the rotating rod 410 is fixedly connected to the output end of the servo motor 411. The servo motor 411 is fixedly installed on the surface of the collection box 104. A linkage plate 412 is fixedly connected to the middle position of the rotating rod 410. A sliding groove 413 is opened at the bottom position of the linkage plate 412. A crossbar 409 is slidably connected inside the sliding groove 413.

[0029] Specifically, the operation of the servo motor 411 causes the rotating rod 410 to rotate. The rotation of the rotating rod 410 causes the linkage plate 412 to pull the bracket 408 on the crossbar 409 to move. This facilitates the connecting plate 407 on the bracket 408 to drive the pull rod 406 to move. This facilitates the pull rod 406 to drive the piston 405 inside the cylinder 304 to move, thereby extracting the liquid inside the horizontal tube 303. When the piston 405 retracts, the horizontal tube 303 is in a closed state. The liquid inside the horizontal tube 303 pushes the cover plate 404, thereby facilitating the discharge of the liquid inside the horizontal tube 303 and making it convenient for the next liquid extraction operation.

[0030] The working principle of this invention is as follows: Liquid enters the interior of cavity 201 through inlet pipe 202. The heat generated by pressure vessel body 1 is conducted to the liquid inside cavity 201 through arc plate 2, and then conducted out through outlet pipe 203. When installing arc plate 2, arc plate 2 is attached to the surface of pressure vessel body 1, and then arm plate 205 is rotated to move sleeve block 207 on docking rod 206. Insert rod 208 on sleeve block 207 is pulled to move insert block 211 to one side of locking block 212. Then insert rod 208 is released, and the elastic force of first spring 210 causes insert block 211 to be locked on locking block 212, thereby completing the installation of arc plate 2. The heated liquid inside the cavity 201 enters the liquid passage pipe 3 through the liquid outlet pipe 203. Then, the liquid passage pipe 3 guides the heated liquid through the bend pipe 301 into the horizontal pipe 303. When the piston 405 moves, a negative pressure is generated inside the horizontal pipe 303 and the bend pipe 301. Then, the horizontal pipe 303 moves downward, and the liquid inside the bend pipe 301 enters the horizontal pipe 303. The second spring 310 controls the horizontal pipe 303 to prevent the liquid inside the bend pipe 301 from flowing back. The operation of the servo motor 411 causes the rotating rod 410 to rotate. The rotation of the rotating rod 410 causes the linkage plate 412 to pull the bracket 408 on the crossbar 409 to move. This facilitates the connecting plate 407 on the bracket 408 to drive the pull rod 406 to move. This facilitates the pull rod 406 to drive the piston 405 inside the cylinder 304 to move, thereby extracting the liquid inside the horizontal tube 303. When the piston 405 retracts, the horizontal tube 303 is in a closed state. The liquid inside the horizontal tube 303 pushes the cover plate 404, thereby facilitating the discharge of the liquid inside the horizontal tube 303.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
