Description

Technical Field

[0001] This utility model relates to the field of petrochemicals, and in particular to a flame arrester for safe production in petrochemicals. Background Technology

[0002] The concept of flame arresters can be traced back to the 19th century. With the development of industry, especially in the fields of petrochemicals, mining, and coal mining, the handling and storage of flammable and explosive substances has become an important safety issue. In order to prevent the spread of flames in pipelines or containers, people began to research and develop flame arresters.

[0003] In the petrochemical industry, some waste flammable gases are generated. These flammable gases need to be prevented from burning during the emission process by flame arresters. However, when traditional flame arresters are used, the burning flammable gases will directly impact the flame arrester core, which will generate a certain amount of impact energy. When this energy rebounds to the delivery pipeline, it may affect the pipeline wall, thus causing some safety problems.

[0004] To address the aforementioned issues, this utility model document proposes a flame arrester for safe production in the petrochemical industry. Utility Model Content

[0005] This utility model provides a flame arrester for safe production in the petrochemical industry. It solves the problem that in the existing technology, some waste flammable gases are generated in the petrochemical industry. These flammable gases need to be prevented from burning during the emission process by flame arresters. However, when traditional flame arresters are used, the burning flammable gases will directly impact the flame arrester core, which will generate a certain impact energy. When this energy rebounds to the conveying pipeline, it may affect the pipe wall and cause some safety problems.

[0006] This utility model provides the following technical solution:

[0007] A flame arrester for safe production in petrochemical industry includes a first sleeve, one end of which has a slot, and a second sleeve is provided at one end of the first sleeve.

[0008] The protective mechanism is located inside the first sleeve and is used to protect the pipeline that transports flammable gases.

[0009] The reinforcement mechanism is installed on the outer wall of the second sleeve to enhance the stability of the device operation.

[0010] In one possible design, the protective mechanism includes a protective cylinder, connecting rods, a connecting block, and a protective cover. The outer wall of the protective cylinder is fixedly connected to the inner wall of the first sleeve. One end of each of the two connecting rods is fixedly connected to the outer wall of the protective cylinder. The same rotating rod is fixedly connected to the side of the two connecting rods that are close to each other. One side of the connecting block is fixedly connected to the outer wall of the protective cover. A rotating hole is provided inside the connecting block, and the inside of the rotating hole is rotatably connected to the outer wall of the rotating rod.

[0011] In one possible design, a through hole is provided at one end of the protective cylinder, and a protective cover is disposed on one side of the through hole, the size of which is larger than that of the through hole.

[0012] In one possible design, the reinforcing mechanism includes a reinforcing ring, locking blocks, insert rings, and rubber rings. The reinforcing ring is fixedly sleeved on the outer wall of the second sleeve. One side of each of the locking blocks is fixedly connected to the outer wall of the first sleeve. Each of the locking blocks has a locking hole inside, and a locking bolt is inserted into each of the locking holes. One side of the reinforcing ring has multiple reinforcing holes, and one end of each locking bolt is threaded into the multiple reinforcing holes. One side of the insert ring is fixedly connected to one end of the second sleeve, and the other side of the insert ring is inserted into the slot. One side of the rubber ring has an installation groove, and the inner wall of the installation groove is fixedly connected to the outer wall of the insert ring.

[0013] In one possible design, a retaining ring is fixedly connected to the inner wall of the second sleeve. A first flame arrester core and a second flame arrester core are placed inside the second sleeve. The first and second flame arrester cores are respectively provided with multiple first flame arrester holes and second flame arrester holes. The size of the multiple second flame arrester holes is smaller than that of the first flame arrester holes. An inner sleeve is threaded to one end of the second sleeve for locking the first and second flame arrester cores. Fixing blocks are fixedly connected to the outer walls of both the second sleeve and the inner sleeve. Each of the multiple fixing blocks is provided with fixing holes. The multiple fixing holes are divided into two groups. A fixing bolt is inserted into the fixing hole of each group. A fixing nut is threaded to the outer wall of each of the two fixing bolts.

[0014] In one possible design, an extension rod is fixedly connected to the outer wall of the protective cover, and a counterweight ball is fixedly connected to the other end of the extension rod.

[0015] In this application, during use, two pipes conveying flammable gases are first fixedly connected to one end of the first sleeve of the inner sleeve box. Then, the first and second flame arrestor cores are sequentially placed inside the second sleeve, ensuring they are supported and correctly positioned by the retaining rings. The retaining ring design effectively prevents the flame arrestor cores from moving or falling out within the sleeve, ensuring their stability and reliability. Next, the inner sleeve is fixed to one end of the second sleeve via a threaded connection, locking the positions of the first and second flame arrestor cores. The threaded connection of the inner sleeve ensures the two flame arrestor cores are firmly fixed, preventing displacement during use and further improving the stability of the flame arrester. Then, a retaining ring is inserted into the slot of the first sleeve, and a rubber ring is installed on the outer wall of the retaining ring. Simultaneously, a locking bolt connects the reinforcing ring to the locking block on the first sleeve. The design of the reinforcing ring and locking bolt enhances the structural strength of the entire device. The combination of the insert ring and rubber ring enhances the sealing between the slot and the insert ring, preventing gas leakage. At this point, the installation of the device is complete. When the gas enters the protective cylinder through the first sleeve, it continues to move into the interior of the second sleeve through the through hole. At this time, the gas in the pipeline will push open the protective cover, successfully enter the second sleeve, and pass through multiple first and second flame arrestor holes until it enters another pipeline. When the gas accidentally burns, it will generate an impact force that instantly rushes towards the first flame arrestor core. At this time, some flames will move along the interior of multiple first and second flame arrestor holes and eventually disappear due to the wall effect. The remaining impact force will reverse and close the protective cover, keeping the impact force inside the device. Finally, it will all be slowly discharged into another pipeline through multiple first and second flame arrestor holes, thus avoiding damage to the gas pipeline by the instantaneous impact force and enhancing the safety of the device.

[0016] In this utility model, the flame arrester for safe production in petrochemical industry can achieve the following through the protective mechanism: normal airflow can push open the protective cover to pass through, while when there is a pressure wave impact when a flame is generated, the protective cover can be driven to close, instantly cutting off the gas passage, and blocking the flame propagation by utilizing the wall effect. It can also protect the pipe wall that transports the gas from damage caused by the pressure wave impact.

[0017] In this utility model, the flame arrester for safe production in petrochemical industry, through the reinforcement mechanism, can achieve the goal of forming a rigid frame between the reinforcement ring and the locking block through the locking bolts, and with the threaded connection of the inner sleeve, ensure that the two flame arresting cores are under long-term pressure without displacement, thereby avoiding the failure of the flame arresting layer due to vibration or pressure fluctuation.

[0018] In this invention, the protective mechanism enhances the safety of the flame arrester through physical protection and counterweight design, while the reinforcement mechanism further improves the stability and safety of the flame arrester by enhancing structural strength and improving sealing.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-4 A flame arrester includes: a first sleeve 1, a slot 12 is provided at one end of the first sleeve 1, and a second sleeve 2 is provided at one end of the first sleeve 1, so that a ring 10 can be inserted into the slot 12 of the first sleeve 1 to quickly assemble the first sleeve 1 and the second sleeve 2.

[0028] A protective mechanism, located inside the first sleeve 1, is used to protect the pipeline transporting flammable gas. The protective mechanism includes a protective cylinder 13, connecting rods 14, a connecting block 15, and a protective cover 16. The outer wall of the protective cylinder 13 is fixedly connected to the inner wall of the first sleeve 1. One end of each of the two connecting rods 14 is fixedly connected to the outer wall of the protective cylinder 13. A common rotating rod is fixedly connected to the side of the two connecting rods 14 that are close to each other. One side of the connecting block 15 is fixedly connected to the outer wall of the protective cover 16. A rotating hole is provided inside the connecting block 15, and the interior of the rotating hole is rotatably connected to the outer wall of the rotating rod. Therefore, when gas enters the protective cylinder 13 through the first sleeve 1, it will continue to pass through the through hole 19. As the gas moves into the second sleeve 2, the gas in the pipeline pushes open the protective cover 16, successfully enters the second sleeve 2, and passes through multiple first and second flame arresters until it enters another pipeline. When the gas accidentally ignites, it generates an impact force that instantly rushes towards the first flame arrester 5. At this time, some flames will move along the inside of the multiple first and second flame arresters and eventually disappear due to the wall effect. The remaining impact force will reverse and close the protective cover 16, keeping the impact force inside the device. Finally, it will all be slowly discharged into another pipeline through the multiple first and second flame arresters, thus avoiding damage to the gas pipeline by the instantaneous impact force and enhancing the safety of the device.

[0029] A reinforcement mechanism, installed on the outer wall of the second sleeve 2, is used to enhance the stability of the device operation. The reinforcement mechanism includes a reinforcement ring 8, locking blocks 9, insert rings 10, and rubber rings 11. The reinforcement ring 8 is fixedly sleeved on the outer wall of the second sleeve 2. One side of each locking block 9 is fixedly connected to the outer wall of the first sleeve 1. Each locking block 9 has a locking hole inside, and a locking bolt is inserted into each locking hole. One side of the reinforcement ring 8 has multiple reinforcement holes, and one end of each locking bolt is threaded into one of the multiple reinforcement holes. Inside, one side of the insert ring 10 is fixedly connected to one end of the second sleeve 2, and the other side of the insert ring 10 is inserted into the inside of the slot 12. One side of the rubber ring 11 has an installation groove, and the inner wall of the installation groove is fixedly connected to the outer wall of the insert ring 10, so that the locking bolt can connect the reinforcing ring 8 to the locking block 9 on the first sleeve 1. The design of the reinforcing ring 8 and the locking bolt enhances the structural strength of the entire device, while the combined design of the insert ring 10 and the rubber ring 11 enhances the sealing between the slot 12 and the insert ring 10, preventing gas leakage.

[0030] This application can be used in the petrochemical field, or in other fields applicable to this application.

[0031] Example 2

[0032] Based on Example 1, the following improvements were made:

[0033] A flame arrester for safe production in the petrochemical industry, whose applications in the petrochemical field include:

[0034] One end of the protective cylinder 13 has a through hole 19, and a protective cover 16 is provided on one side of the through hole 19. The size of the protective cover 16 is larger than that of the through hole 19, so that the gas flow can be cut off and the gas pipeline can be protected from impact.

[0035] A retaining ring 7 is fixedly connected to the inner wall of the second sleeve 2. A first flame-arresting core 5 and a second flame-arresting core 6 are placed inside the second sleeve 2. The first flame-arresting core 5 and the second flame-arresting core 6 each have multiple first and second flame-arresting holes, the size of which is smaller than that of the first flame-arresting holes. An inner sleeve 3 is threaded to one end of the second sleeve 2 to lock the first flame-arresting core 5 and the second flame-arresting core 6. Fixing blocks 4 are fixedly connected to the outer walls of both the second sleeve 2 and the inner sleeve 3. Each fixing block 4 has fixing holes inside, which are evenly divided into two groups. A fixing bolt is inserted into the fixing holes in each group. Both fixing bolts have threaded nuts on their outer walls, allowing the first flame arrestor core 5 and the second flame arrestor core 6 to be sequentially placed inside the second sleeve 2. These are secured by the retaining ring 7 and correctly positioned. The retaining ring 7 effectively prevents the flame arrestor cores from moving or falling out within the sleeve, ensuring their stability and reliability. Then, the inner sleeve 3 is fixed to one end of the second sleeve 2 via a threaded connection, locking the positions of the first flame arrestor core 5 and the second flame arrestor core 6. The threaded connection of the inner sleeve 3 ensures the two flame arrestor cores are firmly fixed, preventing displacement during use and further improving the stability of the flame arrester.

[0036] An extension rod 17 is fixedly connected to the outer wall of the protective cover 16, and a counterweight ball 18 is fixedly connected to the other end of the extension rod 17, so that the protective cover 16 can fall naturally to cover the through hole 19. When there is gas flow, it can be opened, and when there is an impact force inside the device, the gas flow can be quickly cut off, thus enhancing the safety of the device.
