Description

Technical Field

[0001] This utility model relates to the field of vaporization technology, specifically a pipeline chlorine vaporization device. Background Technology

[0002] Chlorine is a key raw material in chemical production, disinfection and sterilization, and industrial synthesis. Its application requires the vaporization of liquid chlorine into gaseous chlorine.

[0003] For example, the liquid vaporization device disclosed in patent number CN215387582U includes a shell, a heating chamber disposed in the shell, and a heater and a temperature detector disposed on the heating chamber. The heating chamber is formed inwardly, and a sealing gasket is sealed at the top of the heating chamber. Although the aforementioned patents have the technical advantage of vaporization, the vaporization channels of the material flow structure are mostly designed with smooth pipe walls. When liquid chlorine flows in the pipe, it is easy to form a laminar boundary layer with limited contact area and low heat transfer efficiency. Furthermore, it is difficult to accurately control the residence time of liquid chlorine in the pipe, and some areas are prone to forming flow "dead zones", resulting in local liquid chlorine retention and incomplete vaporization. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a pipeline-type chlorine vaporization device, which solves the problems of limited contact area and low heat transfer efficiency in the material conveying structure.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A pipeline-type chlorine vaporization device includes: a vaporization structure, wherein a material conveying structure is fixedly connected to the inner wall of the vaporization structure; the material conveying structure includes a spiral vaporization tube, wherein a feed pipe is fixedly connected to the outer wall of the top of the spiral vaporization tube, a discharge pipe is fixedly connected to the outer wall of the bottom of the spiral vaporization tube, and an inner rib is fixedly connected to the inner wall of the spiral vaporization tube, wherein a contact groove is formed on the outer wall of the inner rib.

[0006] Preferably, the contact grooves are arranged in an array along the outer wall of the inner ribs, and the inner ribs are arranged in a ring array along the central point of the spiral vaporization tube. The ring array of inner ribs on the inner wall increases the contact area between liquid chlorine and the tube wall, destroys the laminar boundary layer formed by liquid chlorine on the tube wall, and promotes the formation of turbulent mixing of liquid chlorine.

[0007] Preferably, the vaporization structure includes a vaporization tank, a support leg is fixedly connected to the outer wall of the bottom of the vaporization tank, a support column is fixedly connected to the inner wall of the vaporization tank, a spiral plate is fixedly connected to the outer wall of the support column, a slow-flow hole is opened on the outer wall of the spiral plate, and inlet and outlet pipes are fixedly connected to the outer walls of the top and bottom of the vaporization tank.

[0008] Preferably, the outer wall of the spiral plate is fixedly connected to the inner wall of the vaporization tank, and the slow-flow holes are arranged in an array along the outer wall of the spiral plate. The heating medium enters the interior of the vaporization tank through the inlet and outlet pipes at the top of the vaporization tank and flows along the spiral channel formed by the spiral plate, the inner wall of the vaporization tank, and the outer wall of the spiral vaporization pipe. The spiral structure of the spiral plate extends the flow path of the heating medium, and the slow-flow holes arrayed on its outer wall can break the laminar flow state of the heating medium and avoid insufficient heat exchange caused by excessively fast local flow rates.

[0009] Preferably, the inner wall of the spiral plate is fixedly connected to the outer wall of the spiral vaporization tube, and the inner wall of the vaporization tank is fixedly connected to the outer walls of the feed pipe and the discharge pipe, so as to continuously absorb the heat transferred by the wall of the spiral vaporization tube and gradually change from liquid to gas to complete the vaporization process.

[0010] (III) Beneficial Effects This invention provides a pipeline-type chlorine vaporization device. It has the following beneficial effects: (i) The vaporization structure forms a spiral flow channel through the spiral plate, which, together with the slow flow holes, breaks the laminar flow state, extends the heat exchange path, and avoids uneven local flow velocity, so that the heat of the heating medium can be fully released. At the same time, the fixed connection design between the support column and the spiral plate not only enhances the overall rigidity of the spiral structure, but also offsets the impact load generated by the flow of the heating medium, avoids the deformation of the components during long-term operation, and extends the service life of the device.

[0011] (ii) The material feeding structure extends the residence time through the spiral path of the spiral vaporization tube. The combination design of the inner ribs and the contact groove greatly increases the contact area and effectively avoids the formation of "dead zone" in the pipe by liquid chlorine, eliminating the phenomenon of incomplete vaporization caused by poor local flow. Furthermore, it enhances heat transfer through turbulent mixing and micro eddies, significantly reducing the heat exchange temperature difference and reducing energy consumption.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-7 This utility model provides a technical solution: a pipeline chlorine vaporization device, comprising: a vaporization structure 1, a material conveying structure 2 fixedly connected to the inner wall of the vaporization structure 1; the material conveying structure 2 includes a spiral vaporization pipe 21, an inlet pipe 22 fixedly connected to the outer wall of the top of the spiral vaporization pipe 21, an outlet pipe 23 fixedly connected to the outer wall of the bottom of the spiral vaporization pipe 21, an inner rib 24 fixedly connected to the inner wall of the spiral vaporization pipe 21, and a contact groove 25 formed on the outer wall of the inner rib 24.

[0016] The contact grooves 25 are arranged in an array along the outer wall of the inner ribs 24. The inner ribs 24 are arranged in a ring along the central point of the spiral vaporization tube 21. The inner ribs 24 arranged in a ring along the inner wall increase the contact area between liquid chlorine and the tube wall, destroy the laminar boundary layer formed by liquid chlorine on the tube wall, and promote the formation of turbulent mixing of liquid chlorine.

[0017] The vaporization structure 1 includes a vaporization tank 11. A support leg 12 is fixedly connected to the outer wall of the bottom of the vaporization tank 11. A support column 13 is fixedly connected to the inner wall of the vaporization tank 11. A spiral plate 14 is fixedly connected to the outer wall of the support column 13. A slow flow hole 15 is opened on the outer wall of the spiral plate 14. Inlet and outlet pipes 16 are fixedly connected to the outer walls of the top and bottom of the vaporization tank 11.

[0018] The outer wall of the spiral plate 14 is fixedly connected to the inner wall of the vaporization tank 11. The slow-flow holes 15 are arranged in an array along the outer wall of the spiral plate 14. The heating medium enters the interior of the vaporization tank 11 through the inlet and outlet pipes 16 at the top of the vaporization tank 11 and flows along the spiral channel formed by the spiral plate 14, the inner wall of the vaporization tank 11, and the outer wall of the spiral vaporization pipe 21. The spiral structure of the spiral plate 14 extends the flow path of the heating medium. At the same time, the slow-flow holes 15 arranged in an array on its outer wall can break the laminar flow state of the heating medium and avoid insufficient heat exchange caused by excessive local flow velocity.

[0019] The inner wall of the spiral plate 14 is fixedly connected to the outer wall of the spiral vaporization tube 21, and the inner wall of the vaporization tank 11 is fixedly connected to the outer walls of the feed pipe 22 and the discharge pipe 23. It continuously absorbs the heat transferred from the pipe wall of the spiral vaporization tube 21 and gradually changes from liquid to gas to complete the vaporization process.

[0020] In use, the heating medium enters the vaporization structure 1 through the inlet / outlet pipe 16 at the top of the vaporization tank 11, and heats and vaporizes the material conveying structure 2. The heating medium enters the vaporization tank 11 through the inlet / outlet pipe 16 at the top of the vaporization tank 11 and flows along the spiral channel formed by the spiral plate 14, the inner wall of the vaporization tank 11, and the outer wall of the spiral vaporization pipe 21. The spiral structure of the spiral plate 14 extends the flow path of the heating medium, and the slow-flow holes 15 arrayed on its outer wall can break the laminar flow state of the heating medium, avoiding insufficient heat exchange caused by excessive local flow velocity. The support column 13 is fixedly connected to the spiral plate 14, which not only enhances the structural stability of the spiral plate 14, but also avoids the impact generated when the heating medium flows, which causes the component to deform. Finally, the heating medium is discharged through the inlet / outlet pipe 16 at the bottom of the vaporization tank 11, forming a closed loop circulation, and continuously providing heat for the vaporization of liquid chlorine. The liquid chlorine to be vaporized enters the spiral vaporization tube 21 through the feed pipe 22 at the top of the spiral vaporization tube 21. Due to the spiral structure of the spiral vaporization tube 21, the liquid chlorine is transported downward along the spiral path inside the tube, which prolongs the residence time of the liquid chlorine in the tube and provides sufficient time for heat absorption. At the same time, the inner ribs 24 of the annular array on the inner wall of the spiral vaporization tube 21 increase the contact area between the liquid chlorine and the tube wall, destroy the laminar boundary layer formed by the liquid chlorine on the tube wall, promote the formation of turbulent mixing of the liquid chlorine, and accelerate the heat transfer efficiency from the tube wall to the interior of the liquid chlorine. The contact grooves 25 of the array on the outer wall of the inner ribs 24 further refine the flow path of the liquid chlorine, so that the liquid chlorine forms a small vortex when flowing through the inner ribs 24, avoiding incomplete vaporization of the liquid chlorine due to poor flow in some areas. At the same time, the contact grooves 25 increase the contact points between the inner ribs 24 and the liquid chlorine, further improving the heat exchange efficiency. During the spiral conveying process, liquid chlorine continuously absorbs the heat transferred from the wall of the spiral vaporization pipe 21, gradually transforming from a liquid state into a gaseous state to complete the vaporization process. The completely vaporized chlorine gas continues to flow downward along the spiral vaporization pipe 21 and is finally discharged through the discharge pipe 23 at the bottom and transported to subsequent gas-using equipment.
