Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a horizontal enamel-lined reaction vessel for producing oil and gas gathering and transportation pour point depressants. Background Technology
[0002] Pour point depressants (PPDs) are chemical additives that improve the low-temperature fluidity of oils (such as crude oil, diesel, and lubricating oils). They work by altering the morphology and growth pattern of wax crystals, preventing the formation of a three-dimensional network structure, thereby lowering the pour point and cold filter plugging point of the oil and improving its fluidity at low temperatures. A reaction vessel is the mixing and reaction equipment used for the production of pour point depressants.
[0003] Existing horizontal reactors typically use internal stirring components to mix raw materials. This single stirring method is relatively inefficient and often requires a relatively long stirring time, thus reducing the mixing efficiency of the device and the user experience.
[0004] Therefore, it is necessary to provide a new horizontal enamel-lined reactor for the production of pour point depressants for oil and gas gathering and transportation to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a horizontal enamel-lined reactor for the production of oil and gas gathering and transportation pour point depressants.
[0006] The horizontal enamel-lined reactor for producing pour point depressants for oil and gas gathering and transportation provided by this utility model includes: a reactor body, a support assembly for supporting the reactor body at the bottom, and a mixing assembly for stirring the pour point depressant raw materials inside the reactor body;
[0007] The supporting assembly includes a base plate, a fixedly connected support column is mounted on one side of the top of the base plate, and a rotatably connected hydraulic rod is mounted on the other side of the top of the base plate via a shaft. The top ends of the hydraulic rod and the support column are both hinged to the bottom end of the fixed ring, and the inner wall of the fixed ring is rotatably connected to the outer wall of the vessel body.
[0008] The mixing assembly includes a mixing motor, which is located on one side outside the vessel body. A rotating tube is fixedly connected to the output end of the mixing motor and inserted into the vessel body. Multiple annularly distributed mixing blades are fixedly installed on the outer wall of the rotating tube, and multiple evenly distributed actuating blades are fixedly installed on the inner wall of the vessel body.
[0009] Preferably, a support plate is fixedly connected between the two fixed rings, a drive gear is rotatably connected on the support plate, and a motor for driving the drive gear is fixedly installed on the support plate.
[0010] Preferably, the drive gear is provided with a meshing linkage gear ring on its exterior. The linkage gear ring is fixedly sleeved on the outer wall of the vessel body. Fixed protrusion rings are provided on both sides of the outer wall of the vessel body, and the outer wall of the fixed protrusion ring abuts against and is rotatably connected to the inner wall of the fixed ring.
[0011] Preferably, both ends of the vessel are fixedly connected with end caps by bolts. A feeding pipe is fixedly installed on the outer wall of one end cap, and the inner wall of the end cap on the side with the feeding pipe abuts against and is rotatably connected to the outer wall of the rotating pipe.
[0012] Preferably, a fixedly connected air guide pipe is inserted into the center of the other end cap, and a fixedly connected discharge pipe is inserted into the side wall of the end cap with the air guide pipe, and one end of the air guide pipe located inside the end cap abuts against and is rotatably connected to the end of the rotating pipe.
[0013] Preferably, multiple exhaust pipes are fixedly inserted between two adjacent mixing blades on the outer wall of the rotating tube, and a one-way valve is fixedly connected to each exhaust pipe.
[0014] Preferably, the mixing assembly further includes a fixing frame, which is fixedly installed on the outer wall of the fixing ring near the mixing motor, and the outer wall of the fixing frame is fixedly connected to the outer wall of the mixing motor.
[0015] Compared with related technologies, the horizontal enamel-lined reactor for producing oil and gas gathering and transportation pour point depressants provided by this utility model has the following beneficial effects:
[0016] 1. This utility model, through the rotating frame of the vessel body, allows the vessel body to be rotated first during use to agitate the raw materials inside. During this process, the gentle blades in the mixing component can be controlled to rotate in the opposite direction to agitate the raw materials a second time. This allows for bidirectional mixing of the raw materials, thereby improving the mixing efficiency of the device.
[0017] 2. After the raw materials are mixed and produced, this utility model can control the hydraulic rod in the support component to extend, so that the end of the kettle body away from the discharge pipe can be tilted upward, so that the produced pour point depressant can flow and gather towards one side of the discharge pipe, thereby making the subsequent discharge of the pour point depressant smoother.
[0018] 3. By setting an exhaust pipe on the outer wall of the rotating tube, the external steam can flow into the interior of the rotating tube through the inlet pipe during use. Then, it can be evenly diffused from the inside of the vessel to the outside through the rotating tube. Compared with injecting steam directly from the side wall of the vessel, the interior of the vessel can be heated more evenly, thus enabling the device to control the temperature inside the vessel more accurately in the later stages.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0027] Please see Figures 1 to 5 The present invention provides a horizontal enamel-lined reactor for producing pour point depressants for oil and gas gathering and transportation. The horizontal enamel-lined reactor for producing pour point depressants for oil and gas gathering and transportation includes: a reactor body 1, a support component 2 for supporting the reactor body 1 at the bottom, and a mixing component 3 for stirring the pour point depressant raw materials inside the reactor body 1.
[0028] In the embodiments of this utility model, please refer to Figures 1 to 5The mixing component 3 includes a mixing motor 32, which is located on one side outside the vessel body 1. A rotating tube 33 is fixedly connected to the output end of the mixing motor 32 and inserted into the vessel body 1. Multiple annularly distributed mixing blades 331 are fixedly installed on the outer wall of the rotating tube 33, and multiple evenly distributed actuating blades 12 are fixedly installed on the inner wall of the vessel body 1. The mixing component 3 also includes a fixing frame 31, which is fixedly installed on the outer wall of a fixing ring 22 near the mixing motor 32, and the outer wall of the fixing frame 31 is fixedly connected to the outer wall of the mixing motor 32. A support plate 23 is fixedly connected between the two fixing rings 22, and a rotatably connected drive gear 231 is mounted on the support plate 23. The support plate 23 is fixedly mounted with a motor that drives the drive gear 231. The drive gear 231 is provided with a meshing linkage gear ring 24 on its outside. The linkage gear ring 24 is fixedly sleeved on the outer wall of the vessel body 1. Fixed protruding rings 11 are fixedly sleeved on both sides of the outer wall of the vessel body 1. The outer wall of the fixed protruding ring 11 abuts against and is rotatably connected to the inner wall of the fixed ring 22. The support assembly 2 includes a base plate 21. A fixedly connected support column 211 is mounted on one side of the top of the base plate 21. A rotatably connected hydraulic rod 212 is mounted on the other side of the top of the base plate 21 via a shaft. The top ends of the hydraulic rod 212 and the support column 211 are hinged to the bottom end of the fixed ring 22. The inner wall of the fixed ring 22 is rotatably connected to the outer wall of the vessel body 1.
[0029] It should be noted that by rotating the vessel body 1, during use, the vessel body 1 can be rotated first to move the raw materials inside. During this process, the gentle blades in the mixing component 3 can be rotated in the opposite direction to move the raw materials a second time, thus achieving bidirectional mixing of the raw materials at the same time, thereby improving the mixing efficiency of the device.
[0030] By setting the fixed protruding ring 11, during use, the fixed protruding ring 11 can limit the axial movement of the vessel body 1 through the abutment between the fixed rings 22, thereby preventing the vessel body 1 from sliding in the axial direction and causing the linkage gear ring 24 and the drive gear 231 to be misaligned. This allows the drive gear 231 to stably drive the vessel body 1 to rotate. At the same time, the motor used to control the rotation of the drive gear 231 is a self-locking motor. Therefore, when discharging the pour point depressant later, the adjusted vessel body 1 can be kept in a stable state, reducing the phenomenon of the vessel body 1 swinging randomly during the discharge process.
[0031] With the hydraulic rod 212 in place, when it is necessary to discharge the completed pour point depressant, the hydraulic rod 212 can be extended to lift the vessel body 1 to an inclined state. This allows the pour point depressant inside the vessel body 1 to flow to one side, making the subsequent discharge of the pour point depressant smoother.
[0032] In the embodiments of this utility model, please refer to Figures 1 to 5 Both ends of the vessel body 1 are fixedly connected with end caps 4 by bolts. A feeding pipe 41 is fixedly installed on the outer wall of one end cap 4, and the inner wall of the end cap 4 with the feeding pipe 41 abuts against and is rotatably connected to the outer wall of the rotating pipe 33. A fixedly connected air guide pipe 42 is inserted into the center of the other end cap 4. A fixedly connected discharge pipe 43 is inserted into the side wall of the end cap 4 with the air guide pipe 42, and the end of the air guide pipe 42 located inside the end cap 4 abuts against and is rotatably connected to the end of the rotating pipe 33.
[0033] It should be noted that by abutting the gas guide pipe 42 and the rotating pipe 33, when in use, after connecting the end of the gas guide pipe 42 to the pipe of the external steam generator, the steam generated by the external steam generator can be introduced into the rotating pipe 33, so that the steam can be smoothly diffused into the interior of the vessel 1 through the rotating pipe 33 and the exhaust pipe 332 on its outer wall.
[0034] Furthermore, through the setting of the discharge pipe 43, when it is necessary to discharge the pour point depressant of the production number, when the operator adjusts the vessel body 1 to an inclined state, the pour point depressant inside the vessel body 1 can flow smoothly towards the discharge pipe 43, thereby making the subsequent discharge of the pour point depressant smoother. At the same time, since the inner wall of the end cap 4 is an arc-shaped structure, when the end cap 4 is tilted, the part where the end cap 4 connects to the discharge pipe 43 can be the lowest point inside the vessel body 1, thereby making the discharge of the pour point depressant inside the vessel body 1 more thorough and reducing the residue of the pour point depressant.
[0035] It should also be noted that the end cap 4 is also equipped with a pressure relief valve for relieving pressure on the vessel body 1 and a temperature sensor for detecting the internal temperature of the vessel body 1, so that the operator can flexibly control the internal state of the vessel body 1 during use.
[0036] In the embodiments of this utility model, please refer to Figures 1 to 5 Multiple exhaust pipes 332 are fixedly inserted between two adjacent mixing blades 331 on the outer wall of the rotating tube 33, and a one-way valve is fixedly connected to the exhaust pipe 332.
[0037] It should be noted that by installing a one-way valve on the exhaust pipe 332, the one-way valve can block the exhaust pipe 332 when no gas is injected into the vessel body 1 during use. This can prevent various raw materials from flowing back into the rotating pipe 33 through the exhaust pipe 332, thus avoiding blockage inside the rotating pipe 33.
[0038] The working principle of the horizontal enamel-lined reactor for producing oil and gas gathering and transportation pour point depressants provided by this utility model is as follows:
[0039] When using this device, the operator can first add the various raw materials required for the pour point depressant into the inside of the vessel 1 through the feeding pipe 41. After the raw materials are added, the operator can control the drive gear 231 in the drive assembly to rotate. The rotating drive gear 231 can drive the vessel 1 to rotate inside the fixed ring 22 by meshing with the external linkage gear ring 24. At this time, the rotating vessel 1 can turn the raw materials inside over by the agitator plate 12 on the inner wall to achieve one stirring of the raw materials.
[0040] Furthermore, during this process, the operator can also control the mixing motor 32 in the mixing component 3 to rotate. The rotating mixing motor 32 can drive the rotating tube 33 at the end to rotate in the opposite direction to the rotation of the vessel body 1. During this process, the mixing blades 331 on the outer wall of the rotating tube 33 can perform secondary stirring and mixing of the raw materials, thereby improving the mixing and stirring effect of the raw materials of this device.
[0041] During the mixing of raw materials, external steam can be introduced into the interior of the rotating tube 33 through the gas guide pipe 42 as needed. The steam entering the rotating tube 33 will diffuse inside the vessel 1 through the exhaust pipe 332, so that the steam can come into more uniform and repeated contact with the raw materials inside the vessel 1, which makes it easier for the staff to control the temperature inside the vessel 1.
[0042] After the mixing and production of the pour point depressant is completed, the hydraulic rod 212 in the support assembly 2 can be extended. The extended hydraulic rod 212 can lift the end of the vessel 1 away from the discharge pipe 43, so that the pour point depressant can be gathered towards the side closer to the discharge pipe 43. Then, when the operator opens the discharge pipe 43, the pour point depressant can be discharged more smoothly through the discharge pipe 43, thereby reducing the residue of the pour point depressant inside the vessel 1.
[0043] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0044] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
