Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a tower top condenser capable of preventing leakage. Background Art

[0002] As a key equipment in the chemical, petroleum, pharmaceutical and other industrial fields, the core function of the condenser is that the compressor compresses the working fluid from low-temperature and low-pressure gas into high-temperature and high-pressure gas, and then these high-temperature and high-pressure gases are sent to the condenser for condensation in order to recover valuable substances or carry out subsequent treatment. The air inlet is the channel for the condenser to exchange with the external gas, and its sealing performance directly affects the operating efficiency and safety of the condenser. However, in actual applications, leakage problems often occur at the condenser air inlet, which has become a bottleneck restricting the performance improvement and safe operation of the condenser.

[0003] The Chinese patent discloses: a tower top condenser that prevents leakage, patent application number: 202123326581.2, the patent "includes an outer shell, a head, a tube sheet and a heat exchange tube, and tube sheets are provided at both ends of the outer shell, heads are provided on both sides of the tube sheet, and heat exchange tubes are evenly inlaid on the tube sheet, and the heat exchange tubes include an inner tube and an outer tube, and a drain pipe is provided at one end of the outer tube, and the middle of the drain pipe is inlaid on the head. The heat exchange tube of the tower top condenser that prevents leakage has a double-layer structure, namely an inner tube and an outer tube. When an inner tube breaks, water will enter the gap between the inner tube and the outer tube, and finally be discharged by the drain pipe to remind the user. The user can close the valve of the drain pipe to ensure the overall sealing of the heat exchange tube, thereby ensuring that the entire condenser can continue to be used, avoiding the trouble of paralysis and inability to use, and greatly improving the adaptability. "

[0004] Although the device can close the valve of the drain pipe to ensure the overall sealing of the heat exchange tube, thereby ensuring that the entire condenser can continue to be used and avoiding the trouble of paralysis and inability to use, the device does not have a leak prevention mechanism for the air inlet. During the use of the air inlet, due to factors such as material aging or changes in operating conditions, the sealing performance of the air inlet will gradually decrease, resulting in air inlet leakage, which will not only lead to a decrease in the working efficiency of the condenser and an increase in product losses, but will also pollute the environment and may even cause safety accidents. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a leakage-proof tower top condenser to solve the problem that the sealing performance of the air inlet will gradually decrease due to factors such as material aging or changes in operating conditions, thereby causing air inlet leakage, which will not only lead to a decrease in the working efficiency of the condenser and an increase in product losses, but also cause pollution to the environment and may even cause safety accidents.

[0006] Based on the above purpose, the utility model provides a tower top condenser for preventing leakage, including a condenser body, a feed pipe is arranged on the top of the condenser body, a feeding pipe is arranged on the top of the feed pipe, flanges are arranged on the opposite surfaces of the feed pipe and the feeding pipe, the flanges are fitted to each other and fixed by bolts, an anti-leakage mechanism for preventing gas leakage is arranged between the connection of the feed pipe and the feeding pipe, the anti-leakage mechanism includes an anti-leakage sleeve arranged between the outer walls of the feed pipe and the feeding pipe, fixing belts are fixedly connected at both ends of the anti-leakage sleeve, and the fixing belts are divided into The invention relates to a novel material packaging material, wherein the material packaging material is fixedly connected to the outer wall of the feed pipe and the feed pipe, the outer wall of the feed pipe is fixedly connected with a lower leakage-proof box, the outer wall of the feed pipe is fixedly connected with an upper leakage-proof box, the lower leakage-proof box and the upper leakage-proof box are fixed by bolts, a slide groove is provided on the side of the upper leakage-proof box close to the lower leakage-proof box, an extrusion spring is fixedly connected inside the slide groove, one end of the extrusion spring is fixedly connected with an leakage-proof ring, the leakage-proof ring is slidably connected in the slide groove, a leakage-proof groove is provided on the side of the lower leakage-proof box close to the upper leakage-proof box, and one end of the leakage-proof ring extends into the leakage-proof groove.

[0007] Preferably, the anti-leakage mechanism also includes an alarm trigger box fixedly connected to the top of the upper anti-leakage box, a movable plate is slidably connected to the inside of the alarm trigger box, one end of the movable plate extends into the upper anti-leakage box and contacts the outer wall of the anti-leakage sleeve, a contact block is fixedly connected to the top of the movable plate, an alarm is fixedly connected to the top of the upper anti-leakage box, a pressure sensor is fixedly connected to the top of the inner wall of the alarm trigger box, and the top of the contact block contacts the bottom of the pressure sensor.

[0008] Preferably, the inner walls of the lower anti-leakage box and the upper anti-leakage box are both provided with limiting grooves, and shielding rings are placed between the inner parts of the limiting grooves.

[0009] Preferably, the anti-leakage sleeve is made of a flexible material.

[0010] Preferably, the bottom shape of the inner wall of the leakage-proof groove is wavy, the shape of one end of the leakage-proof ring is also wavy, the wavy shape set on the leakage-proof ring and the wavy shape set on the leakage-proof groove are staggered, and the outer wall of the leakage-proof ring and the inner wall of the leakage-proof groove are adapted to each other.

[0011] Preferably, the blocking ring is in the shape of an I-shape.

[0012] Preferably, the movable plate is shaped like an inverted triangle.

[0013] Preferably, the pressure sensor and the alarm are electrically connected.

[0014] Preferably, the outer walls of the feed pipe and the delivery pipe are both inlaid with transparent observation windows.

[0015] The beneficial effects of the utility model are as follows: through the linkage design of the anti-leakage sleeve and the movable plate, rapid detection and alarm of gas leakage are realized. When leakage occurs at the connection between the feed pipe and the feeding pipe, the anti-leakage sleeve will expand rapidly to perform preliminary anti-leakage and squeeze the movable plate, triggering the alarm to sound an alarm, thereby reminding the maintenance personnel to quickly handle it. This design effectively shortens the time for leak discovery and reduces production interruptions and losses caused by leakage. Secondly, through the combined use of the lower anti-leakage box, the upper anti-leakage box and the shielding ring, secondary protection of leaking gas is achieved. Even if the anti-leakage sleeve fails to completely prevent gas leakage, the shielding ring between the lower anti-leakage box and the upper anti-leakage box can effectively cover the connection. At the same time, the design of the extrusion spring squeezing the anti-leakage ring so that the anti-leakage ring fits tightly in the anti-leakage groove ensures that even if a gap appears at the connection, gas leakage can be effectively prevented. Through multi-level protection, it can prevent the gas from further diffusion, avoiding factors such as aging of the connection port or changes in working conditions, and the sealing performance of the air inlet will gradually decrease, thereby causing air inlet leakage, ensuring the working efficiency of the condenser, avoiding product losses and environmental pollution, and preventing safety accidents.

[0026] like Figures 1 to 5 As shown, a leakage-proof tower top condenser comprises a condenser body 1, a feed pipe 2 is arranged on the top of the condenser body 1, a feeding pipe 3 is arranged on the top of the feed pipe 2, flanges 4 are arranged on the opposite surfaces of the feed pipe 2 and the feeding pipe 3, the flanges 4 are fitted together and fixed by bolts, and a leakage-proof mechanism for preventing gas leakage is arranged between the connection of the feed pipe 2 and the feeding pipe 3. Multi-level protection is achieved by the leakage-proof mechanism, so that the gas can be prevented from further diffusion, and factors such as aging of the connection port or changes in working conditions are avoided, which will cause the sealing performance of the air inlet to gradually decrease, thereby causing air inlet leakage, thereby ensuring the working efficiency of the condenser, avoiding product loss and environmental pollution, and preventing safety accidents.

[0027] For further information, see Attachment Figures 2 to 5As shown, the leakage prevention mechanism includes a leakage prevention sleeve 5 which is sleeved between the outer walls of the feed pipe 2 and the feeding pipe 3. The leakage prevention sleeve 5 is made of flexible material. Both ends of the leakage prevention sleeve 5 are fixedly connected with fixing belts 6, which are respectively fixedly connected to the outer walls of the feed pipe 2 and the feeding pipe 3. The outer wall of the feed pipe 2 is fixedly connected with a lower leakage prevention box 7, and the outer wall of the feeding pipe 3 is fixedly connected with an upper leakage prevention box 8. The lower leakage prevention box 7 and the upper leakage prevention box 8 are fixed by bolts. A slide groove 9 is provided on the side of the upper leakage prevention box 8 close to the lower leakage prevention box 7. An extrusion spring 10 is fixedly connected inside the slide groove 9. One end of the extrusion spring 10 is fixedly connected with an leakage prevention ring 11. The leakage prevention ring 11 is slidably connected in the slide groove 9. A leakage prevention groove 12 is provided on the side of the lower leakage prevention box 7 close to the upper leakage prevention box 8. The bottom shape of the inner wall of the leakage prevention groove 12 is wavy. One end of 11 is also wavy in shape, and the wavy shape arranged on the anti-leakage ring 11 and the wavy shape arranged on the anti-leakage groove 12 are staggered with each other, the outer wall of the anti-leakage ring 11 and the inner wall of the anti-leakage groove 12 are adapted to each other, and one end of the anti-leakage ring 11 extends into the anti-leakage groove 12, and the anti-leakage mechanism also includes an alarm trigger box 15 fixedly connected to the top of the upper anti-leakage box 8, and a movable plate 16 is slidably connected inside the alarm trigger box 15, and one end of the movable plate 16 extends into the upper anti-leakage box 8 and contacts the outer wall of the anti-leakage sleeve 5, and a contact block 17 is fixedly connected to the top of the movable plate 16, and an alarm 19 is fixedly connected to the top of the inner wall of the alarm trigger box 15. A pressure sensor 18 is fixedly connected, and the top of the contact block 17 contacts the bottom of the pressure sensor 18, and the pressure sensor 18 and the alarm 19 are electrically connected;

[0028] When the external device delivers gas to the feeding pipe 3, the feeding pipe 3 delivers the gas to the feeding pipe 2. When there is a leak between the connection between the feeding pipe 2 and the feeding pipe 3, the gas will leak into the anti-leakage sleeve 5, and the anti-leakage sleeve 5 will play a preliminary role in preventing leakage. At this time, the anti-leakage sleeve 5 begins to expand. When the anti-leakage sleeve 5 expands, it will contact the movable plate 16. Then the anti-leakage sleeve 5 will squeeze the movable plate 16 to slide upward in the alarm trigger box 15. When the movable plate 16 slides upward, it will contact the pressure sensor 18. The pressure sensor 18 is used to detect the pressure applied by the movable plate 16. When the pressure sensor 18 detects the pressure, it will send a signal to the alarm 19. Then the alarm 19 starts to sound an alarm, thereby reminding the maintenance personnel to perform maintenance. When there is gas from the anti-leakage sleeve 5 leaks out into the lower anti-leakage box 7 and the upper anti-leakage box 8, the shielding ring 14 squeezed between the lower anti-leakage box 7 and the upper anti-leakage box 8 prevents leakage. When a gap is generated between the feed pipe 2 and the feeding pipe 3 after a long time of use, a gap will be caused at the connection between the lower anti-leakage box 7 and the upper anti-leakage box 8. Then the squeezing spring 10 will squeeze the anti-leakage ring 11, so that the anti-leakage ring 11 can still fit tightly in the anti-leakage groove 12 to prevent gas from leaking to the outside. Then, the wave shape staggered between the anti-leakage ring 11 and the anti-leakage groove 12 further improves the sealing performance and prevents gas leakage. At the same time, the lower anti-leakage box 7 and the upper anti-leakage box 8 protect the connection between the feed pipe 2 and the feeding pipe 3 to avoid external collision and deformation, which is convenient for use.

[0029] For further information, see Attachment Figure 5 As shown, the inner walls of the lower anti-leakage box 7 and the upper anti-leakage box 8 are provided with limiting grooves 13, and a blocking ring 14 is placed between the inside of the limiting grooves 13. The blocking ring 14 is in the shape of an "I" character, and the blocking ring 14 and its shape can cover the connection between the lower anti-leakage box 7 and the upper anti-leakage box 8, thereby improving the sealing performance.

[0030] For further information, see Attachment Figure 4 As shown, the shape of the movable plate 16 is an inverted "triangle", and the shape of the movable plate 16 can facilitate squeezing of the movable plate 16 after the anti-leakage sleeve 5 expands.

[0031] For further information, see Attachment Figure 2 As shown, the outer walls of the feed pipe 2 and the delivery pipe 3 are both inlaid with transparent observation windows, through which the internal conditions of the lower anti-leakage box 7 and the upper anti-leakage box 8 can be observed.
