Description

Technical Field

[0001] This invention relates to the field of gas treatment technology, specifically to a safe treatment mechanism for residual gas inside gas production cylinders. Background Technology

[0002] If residual gas in gas production cylinders is directly discharged, it may harm the health of operators, pollute the surrounding environment, and even cause safety accidents in special circumstances such as encountering open flames. Therefore, safe and effective treatment of residual gas in gas production cylinders is an indispensable and important part of the gas production process.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN222855050U and announcement date of 2025-05-13) discloses a gas purification device, which includes a gas purification device body, and an air intake component and a dehumidification component disposed inside the gas purification device body. Air outlets are provided on both sides of the top of the gas purification device body, and an air inlet is provided on one side of the bottom of the gas purification device body. A negative ion generator is fixedly connected to the top inside the gas purification device body by bolts. A filter plate is disposed inside the air inlet, with one end of the filter plate passing through the air inlet and interlocked with the air inlet. The air intake component draws gas in from the air inlet, filters it through the filter plate, and then it enters the gas purification device body. The dehumidification component dries the gas, and the negative ions generated by the negative ion generator disinfect and sterilize the gas. Finally, the disinfected and sterilized gas is discharged through the air outlets.

[0004] There is also prior art 2 (Chinese patent with announcement number CN112354340A and announcement date of 2021-02-12) a device for purifying and recovering residual vinyl chloride gas, including an acid washing tower and an alkaline washing tower. The top of the acid washing tower and the alkaline washing tower are connected by a connecting pipe. The acid washing tower is equipped with an acid washing tower water mist collector, an acid washing tower spray head, and an acid washing tower packing layer. The bottom of the acid washing tower and the acid washing tower spray head are connected by an acid liquid circulation pipe. An acid liquid pipeline filter and an acid liquid circulation pump are installed on the acid liquid circulation pipe. The alkaline washing tower is equipped with an alkaline washing tower water mist collector, an alkaline washing tower spray head, and an alkaline washing tower packing layer. The bottom of the alkaline washing tower and the alkaline washing tower spray head are connected by an alkaline liquid circulation pipe. An alkaline liquid pipeline filter and a circulation pump are installed on the alkaline liquid circulation pipe. A recovery gas pipe is installed at the top of the alkaline washing tower. In practical use, the acid-base scrubbing tower purifies the recovered gas, removes ammonia from the recovered gas, eliminates the impact of ammonia in the recovered gas on the system, improves product quality, increases system load, and creates good benefits.

[0005] While existing technologies treat gases through spraying and filtration, they still have certain shortcomings in practical applications. On the one hand, the sprayed liquid is mostly sprayed in a fixed direction, resulting in a limited contact area with the gas. This causes some gas to fail to fully react with the liquid, affecting the purification effect. On the other hand, the gas often flows in a straight line within the treatment tank at a relatively high velocity, resulting in a short contact time with the filter medium, making it difficult to achieve deep filtration. Furthermore, traditional devices lack effective intervention in the gas flow state, leading to uneven gas diffusion and further reducing filtration efficiency.

[0006] Therefore, we propose a safe handling mechanism for residual gas inside gas production cylinders to address the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a safe treatment mechanism for residual gas inside gas production cylinders, in order to solve the problems mentioned in the background art. Currently, most spray liquids on the market are sprayed in a fixed direction, resulting in a limited contact area with the gas. This leads to some gas failing to fully react with the liquid, affecting the purification effect. The gas often flows in a straight line in the treatment tank, with a relatively high flow rate and a short contact time with the filter medium, making it difficult to achieve deep filtration. Furthermore, traditional devices lack effective intervention in the gas flow state, resulting in uneven gas diffusion and further reducing filtration efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a safety treatment mechanism for residual gas inside a gas production cylinder, comprising a treatment tank, wherein the treatment tank has interfaces for supplying and discharging residual gas on its downward sides, and a mounting frame is fixedly connected to the side of the treatment tank, and a liquid tank for holding filter liquid is fixedly connected inside the mounting frame, and a filter plate for filtering gas is fixedly connected inside the treatment tank, a rotating ring is rotatably connected inside the treatment tank, and a spray pipe is provided through the bottom of the rotating ring, and a rotating mechanism is provided on the rotating ring. The rotating mechanism realizes the rotating spraying of liquid by the supply of liquid inside the liquid tank, and a flow-turbulence mechanism is also provided between the bottom of the filter plate and the top of the treatment tank. The flow-turbulence mechanism realizes the flow-turbulence of gas by the swinging of the flow-turbulence plate contained therein, thereby improving the gas diffusion and filtration efficiency.

[0009] Preferably, the rotating mechanism includes a drive plate, which is fixedly connected to the middle of the outer side of the rotating ring. The diameter of the middle part of the rotating ring is smaller than the maximum value of the diameters of its upper and lower ends. At the same time, the outermost end of the drive plate does not exceed the outermost ends of the upper and lower sides of the rotating ring. The upper and lower ends of the rotating ring are sealed and fitted to the inner wall of the processing tank.

[0010] Preferably, a connecting pipe is connected through the bottom of the liquid tank, and the other end of the connecting pipe is connected to the side of the processing tank. The lower end of the connecting pipe corresponds to the middle position of the rotating ring. The drive plate is arranged in an inclined structure, and the liquid inside the liquid tank impacts the drive plate to drive the rotating ring to rotate.

[0011] Preferably, the rotating ring has a buffer cavity inside, and the sides of the rotating ring are provided with connecting grooves that communicate with the buffer cavity. Water from inside the liquid tank enters the buffer cavity through the connecting grooves and is then sprayed outward from the spray pipe.

[0012] Preferably, a pressure plate is slidably connected inside the buffer cavity, and the side of the pressure plate is in contact with the inner wall of the buffer cavity. A first spring is fixedly connected between the upper part of the pressure plate and the buffer cavity, and a striking block is fixedly connected to the lower surface of the pressure plate. In the initial state, the position of the pressure plate is higher than the position of the connecting groove, and the pressure plate slides upward along the buffer cavity under the action of water buoyancy.

[0013] Preferably, an air guide pipe is provided through the side of the treatment tank, with the lower end of the air guide pipe located below the rotating ring and the upper end of the air guide pipe located above the rotating ring and between the filter plate. The air guide pipe is a one-way pipe from bottom to top, and an auxiliary seat is fixedly connected to the top of the treatment tank.

[0014] Preferably, the turbulence mechanism includes a fixed frame, which is fixedly connected to the inside of the processing tank, and a linkage shaft is rotatably connected to the fixed frame. The lower end of the linkage shaft is fixedly connected to the middle of the upper surface of the rotating ring, while the upper end of the linkage shaft extends into the inside of the auxiliary seat.

[0015] Preferably, the auxiliary seat has air supply soft bags arranged in a ring-shaped array on the inner side, and the lower end of the air supply soft bag is provided with a connecting air tube. The upper end of the linkage shaft is fixedly connected to an abutment plate. When the abutment plate rotates under the drive of the linkage shaft, the changing end of the abutment plate abuts against the air supply soft bag.

[0016] Preferably, a positioning shaft is fixedly connected to the lower surface of the filter plate, and a baffle is rotatably connected to the outer side of the positioning shaft. A torsion spring is fixedly connected between the side of the baffle and the end of the positioning shaft. A connecting soft bag is fixedly connected to the upper surface of the baffle plate. The lower end of the connecting air tube extends through to the lower surface of the filter plate and communicates with the upper surface of the connecting soft bag.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) It is equipped with a liquid tank and a filter plate. The filtered liquid inside the liquid tank is transported to the treatment tank through the connecting pipe. The water is sprayed out from the spray pipe through the rotating ring, which initially removes soluble impurities and some particulate matter in the gas. At the same time, the filter plate can further filter the gas after spray treatment, intercepting solid particles and impurities that have not been absorbed by the spray. The dual filtration mechanism significantly improves the cleanliness of the gas treatment.

[0018] (2) A drive plate is fixedly connected to the side of the rotating ring. After the water inside the liquid tank flows to the rotating ring, it will impact the inclined drive plate. Under the action of the water flow impact force, the rotating ring will rotate stably around its central axis. During the rotation of the rotating ring, the spray pipe below it will also rotate, so that the filtered liquid is evenly sprayed inside the treatment tank in a rotating spray manner, which expands the spray coverage area, so that the gas and liquid can come into contact and mix more fully, and improves the dissolution and washing effect of impurities in the gas.

[0019] (3) In the initial state, the pressure plate in the buffer chamber is higher than the connecting groove. As the liquid continuously enters the buffer chamber, the water level gradually rises. The pressure plate slides upward under the action of the buoyancy of the water. When the water supply stops, the liquid stops entering the buffer chamber. At this time, under the action of the elastic restoring force of the first spring, the pressure plate slides downward, and its knocking block will knock on the upper end of the spray pipe, effectively preventing the spray pipe from being blocked by impurities and affecting the spraying effect, and ensuring the continuous stability of the spraying process.

[0020] (4) When the rotating ring rotates, it synchronously drives the linkage shaft to rotate. When the contact plate rotates to contact a certain gas supply soft bag, the connecting soft bag is inflated and expands, which in turn pushes the baffle plate to rotate and stretches the torsion spring. Each baffle plate can swing alternately, forming an effective disturbance to the gas located below the filter plate in the treatment tank, breaking the laminar flow state of the gas, promoting the gas to fully diffuse and mix, increasing the contact area and contact time between the gas and the filter plate, thereby significantly improving the gas filtration efficiency and purification effect.

[0021] (5) A gas guide pipe is opened through the side of the treatment tank. Its lower end is located below the rotating ring, and its upper end is located between the rotating ring and the filter plate. It is a one-way pipe from bottom to top. It can guide part of the gas that has undergone preliminary spray treatment below the rotating ring to the area above the rotating ring and below the filter plate. After merging with the gas in this area, it will be turbulent and filtered again, which further improves the thoroughness of gas treatment and avoids the problem of insufficient local gas treatment.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: As Figure 1 - Figure 3 and Figure 5The present invention provides the following technical solution: a safety treatment mechanism for residual gas in a gas production cylinder, wherein the treatment tank 1 is provided with interfaces for supplying and discharging residual gas on its lower sides, and a mounting frame 2 is fixedly connected to the side of the treatment tank 1, and a liquid tank 3 for holding filter liquid is fixedly connected inside the mounting frame 2, and a filter plate 14 for filtering gas is fixedly connected inside the treatment tank 1, a connecting pipe 4 is connected through the lower part of the liquid tank 3, and the other end of the connecting pipe 4 is connected to the side of the treatment tank 1, a gas guide pipe 5 is provided through the side of the treatment tank 1, and the lower end of the gas guide pipe 5 is located below the rotating ring 8, and the upper end of the gas guide pipe 5 is located above the rotating ring 8 and between the filter plate 14, the gas guide pipe 5 is a one-way pipe from bottom to top, and an auxiliary seat 6 is fixedly connected to the top of the treatment tank 1.

[0026] In actual operation, the gas production cylinder to be treated is first connected to the ports on both sides of the treatment tank 1 via a pipe. One port serves as the inlet for the residual gas, and the other as the outlet for the treated gas. Next, an appropriate amount of filter liquid, such as an acidic solution, alkaline solution, or water selected according to the properties of the residual gas to be treated, is injected into the liquid tank 3. Then, the relevant liquid supply device is activated, and the filter liquid inside the liquid tank 3 is transported to the treatment tank 1 through the connecting pipe 4. The liquid enters the buffer chamber 12 inside the rotating ring 8 through the connecting grooves 11 spaced apart on its side, and... The residual gas sprayed outward from the spray pipe 13 and entering the treatment tank 1 through the inlet is fully in contact with the sprayed filter liquid as it flows upward. Soluble impurities and some particulate matter in the gas are absorbed by the liquid, achieving preliminary purification. The gas after preliminary purification continues to flow upward, and part of the gas is guided through the gas guide pipe 5 to the area between the rotating ring 8 and the filter plate 14. The filter plate 14 further intercepts solid particles and impurities in the gas that have not been absorbed by the spray, achieving deep purification. The purified gas is finally discharged from the docking port on the other side of the treatment tank 1, completing the entire safe treatment process of the residual gas.

[0027] Example 2: Figure 3 - Figure 5The present invention provides the following technical solution: a safety treatment mechanism for residual gas inside a gas production cylinder, comprising a rotating ring 8 rotatably connected inside the treatment tank 1, with a spray pipe 13 penetrating below the rotating ring 8, and a rotating mechanism on the rotating ring 8. The rotating mechanism achieves rotating spraying of the liquid by supplying liquid from inside the liquid tank 3. The rotating mechanism includes a drive plate 7, which is fixedly connected to the outer middle of the rotating ring 8. The diameter of the middle of the rotating ring 8 is smaller than the maximum value of the diameters at its upper and lower ends. Simultaneously, the outermost end of the drive plate 7 does not exceed the outermost ends of the upper and lower sides of the rotating ring 8. The upper and lower ends of the rotating ring 8 are sealed and fitted to the inner wall of the treatment tank 1. The lower end of the connecting pipe 4 corresponds to the middle position of the rotating ring 8. 7 is arranged in an inclined structure, and the liquid impact drive plate 7 inside the liquid tank 3 drives the rotating ring 8 to rotate. The rotating ring 8 has a buffer cavity 12 inside, and the side of the rotating ring 8 is provided with a connecting groove 11 that communicates with the buffer cavity 12. The water inside the liquid tank 3 enters the buffer cavity 12 through the connecting groove 11 and is sprayed outward from the spray pipe 13. The buffer cavity 12 is slidably connected with a pressure plate 16, and the side of the pressure plate 16 is in contact with the inner wall of the buffer cavity 12. The upper part of the pressure plate 16 is fixedly connected to the buffer cavity 12, and the lower surface of the pressure plate 16 is fixedly connected with a striking block 17. In the initial state, the position of the pressure plate 16 is higher than the position of the connecting groove 11. Under the action of the buoyancy of the water, the pressure plate 16 slides upward along the buffer cavity 12.

[0028] When the liquid flows towards the rotating ring 8, it impacts the drive plate 7, which is inclined in the middle of the outer side of the rotating ring 8. Since the drive plate 7 is fixedly connected to the rotating ring 8, and the upper and lower ends of the rotating ring 8 are sealed against the inner wall of the treatment tank 1, the rotating ring 8 begins to rotate stably around its central axis under the impact of the water flow. Initially, the pressure plate 16 in the buffer chamber 12 is higher than the connecting groove 11. As the liquid continues to enter, the water level gradually rises. Under the action of the buoyancy of the water, the pressure plate 16 slides upward along the inner wall of the buffer chamber 12 and compresses the first spring 15. The liquid entering the buffer chamber 12 is then sprayed outward from the spray pipe 13 installed below the rotating ring 8. Since the rotating ring 8 is rotating, the spray pipe 13 also moves with it. The rotation of the ring causes the filtered liquid to be evenly sprayed inside the treatment tank 1 in a rotary spray manner in the area below the rotating ring 8. As it flows upward, it comes into full contact with the filtered liquid in the rotary spray, expanding the spray coverage area and allowing the gas and liquid to come into more thorough contact and mix, thus improving the dissolution and washing effect of impurities in the gas. When the liquid supply stops, the liquid no longer enters the buffer chamber 12. At this time, under the elastic restoring force of the first spring 15, the pressure plate 16 slides down quickly, and the knocking block 17 fixedly connected to its lower surface knocks on the upper end of the spray pipe 13. The vibration generated by the knocking effectively prevents the spray pipe 13 from being blocked by impurities, thus ensuring the continuous stability of the spraying process.

[0029] Example 3: Figure 6 - Figure 10 The present invention provides the following technical solution: a safety treatment mechanism for residual gas inside a gas production cylinder, wherein a turbulence mechanism is provided between the lower part of the filter plate 14 and the top of the treatment tank 1. The turbulence mechanism achieves gas turbulence by swinging the turbulence plate 19 included therein, thereby improving gas diffusion and filtration efficiency. The turbulence mechanism includes a fixing frame 9, which is fixedly connected to the inside of the treatment tank 1. A linkage shaft 10 is rotatably connected to the fixing frame 9, and the lower end of the linkage shaft 10 is fixedly connected to the middle of the upper surface of the rotating ring 8. At the same time, the upper end of the linkage shaft 10 extends into the inside of the auxiliary seat 6, and the auxiliary seat 6 has a ring-shaped arrangement on its inner side. An air supply soft bag 20 is distributed and a connecting air tube 18 is provided through the lower end of the air supply soft bag 20. An abutment plate 21 is fixedly connected to the upper end of the linkage shaft 10. When the abutment plate 21 rotates under the drive of the linkage shaft 10, the abutment plate 21 abuts the air supply soft bag 20 at its variable end. A positioning shaft 23 is fixedly connected to the lower surface of the filter plate 14, and a baffle plate 19 is rotatably connected to the outer side of the positioning shaft 23. A torsion spring 24 is fixedly connected between the side of the baffle plate 19 and the end of the positioning shaft 23. A connecting soft bag 22 is fixedly connected to the upper surface of the baffle plate 19. The lower end of the connecting air tube 18 extends through to the lower surface of the filter plate 14 and communicates with the upper surface of the connecting soft bag 22.

[0030] When the rotating ring 8 rotates, it drives the linkage shaft 10 to rotate synchronously. The contact plate 21 at the upper end of the linkage shaft 10 rotates inside the auxiliary seat 6. Since the air supply soft bags 20 are arranged in a ring inside the auxiliary seat 6, when the contact plate 21 rotates to contact a certain air supply soft bag 20, it will squeeze it. The gas inside the squeezed air supply soft bag 20 is forced into the connected soft bag 22 through the connecting air pipe 18. The connected soft bag 22 expands due to inflation, which in turn pushes the baffle 19 to rotate around the positioning shaft 23 and stretches the torsion spring 24. When the contact plate 21 rotates away from the air supply soft bag 20, The gas supply soft bag 20 is no longer compressed and returns to its original shape, stopping the supply of gas to the connecting soft bag 22. The gas in the connecting soft bag 22 flows back or is released naturally. The baffle 19 rotates in the opposite direction to its initial position under the elastic restoring force of the torsion spring 24. This cycle repeats, with each baffle 19 swinging alternately to effectively disturb the merged gas, promoting full diffusion and mixing of the gas, increasing the contact area and contact time with the filter plate 14. The gas after being disturbed passes upward through the filter plate 14, which further intercepts solid particles and impurities in the gas that have not been absorbed by the spray, achieving deep purification.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
