Description

Technical Field

[0001] The present invention relates to the field of corrosion inhibitor preparation, and more specifically, to a device and method for preparing a high-temperature corrosion inhibitor for a distillation device. Background Art

[0002] A distillation unit is a separation device that uses different boiling points between liquids to separate them. It achieves the purpose of purifying the mixture by vaporizing a component in the liquid mixture through heating and then condensing it into a liquid. During the distillation process, especially under high temperature conditions, the metal materials in the distillation unit may be corroded by various corrosive substances, such as acidic substances (such as HCl, H2S, etc.) produced during the oil refining process and organic acids such as cyclohexane acid. If these corrosive substances cannot be neutralized or removed in time, they will cause serious corrosion to the surface of the equipment. High-temperature corrosion inhibitors are required. Corrosion inhibitors can effectively neutralize or adsorb acidic substances and other corrosive substances produced during the distillation process to prevent them from corroding the surface of the equipment.

[0003] Among them, the patent with publication number CN213761505U discloses a device for preparing high-temperature acidizing corrosion inhibitor for oil wells, including a mixing box, a supporting foot, a first motor, a stirring shaft and a quantitative feeding device. A quantitative feeding device is arranged on the top of the mixing box, three loading boxes are arranged on the top of the quantitative feeding device, and blanking boxes are arranged at the bottom of the three loading boxes. Rotating rollers are installed inside the blanking boxes, and a driving mechanism is installed at the front end of the three blanking boxes. The rotation of the rotating rollers is controlled by an active synchronous wheel and a driven synchronous wheel inside the driving mechanism.

[0004] When this structure is in use, the driving mechanism drives the rotating rollers of the three blanking boxes to rotate, and the outer diameters of the active synchronous wheel and the driven synchronous wheel are selected according to the proportion of the mixed agent, thereby controlling the rotation speed of the rotating rollers and controlling the blanking of the rotating rollers during rotation, so that various mixed agents in different charging boxes are added according to the proportion. However, when mixing materials, this structure uses a single stirring shaft to mix various raw materials, which is not easy to fully mix together, and the raw materials are easily diffused by the traction force of stirring during mixing, resulting in a poor chemical reaction effect and low quality of the final product of the desired corrosion inhibitor intermediate. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device and method for preparing a high-temperature corrosion inhibitor for a distillation device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-temperature corrosion inhibitor preparation device for a distillation device, comprising a base, on which a mixing component is arranged.

[0007] The mixing assembly includes a support frame arranged in the middle of the base, the top of the base is movably connected to a temperature control box through a hinge, both ends of the support frame are equipped with rotating shafts through flanges, and one end of each rotating shaft extends to the base and is rotatably connected to the base, one side of the bottom of the inner cavity of the base is rotatably connected to a hydraulic rod through an axle pin, and the output end of the hydraulic rod extends to one side of the bottom of the support frame and is rotatably connected to the support frame through an axle pin.

[0008] It can be seen that in the above technical solution, the support frame is driven by a hydraulic rod to rotate along the axis point of the connection between the rotating shaft and the base through the rotating shaft, so that the support frame can swing in the base, shaking the raw materials when mixing in the inner cavity, thereby improving the mixing efficiency and effect.

[0009] A protection box is installed on the support frame by bolts, and a plurality of support shafts are arranged at the bottom of the inner cavity of the protection box, and the plurality of support shafts are installed on the support frame by bearings, and a mixing barrel is arranged between each two adjacent support shafts, and a sealing cover is inserted at one end of the mixing barrel, and two groups of inner cavities are arranged inside the mixing barrel, and a valve is arranged at one end of one group of inner cavities, the two inner cavities are connected, and a screen is clamped at one end of each of the inner cavities, and mixing oblique rods are inserted in the two inner cavities, and slip rings are fixedly arranged at the ends of the two inner cavities close to each other, and a slider is slidably connected to each of the slip rings, a vibration rod is inserted on the slider, and the vibration rod extends to the outside of the inner cavity.

[0010] It can be seen that in the above technical solution, the raw materials pass through the valve and are transported to the two groups of inner cavities through the valve. At the same time, the raw materials can be diverted through the baffle of the mixing oblique rod in the inner cavity to avoid accumulation. When the driven wheel rotates, it drives the supporting shaft to rotate. The rotation of the supporting shaft rubs against the mixing barrel, and then the mixing barrel rotates. The rotation of the mixing barrel drives the rotation of each inner cavity, the screen and the mixing oblique rod, so that the raw materials can be mixed in the inner cavity.

[0011] A servo motor is installed on one side of the bottom of the support frame by bolts, a driving wheel is provided at the output end of the servo motor, a driven wheel is fixedly provided at one end of each of the supporting shafts, belts are sleeved on the outer sides of the driving wheel and the driven wheel, a plurality of tensioning wheels installed on the support frame are provided on the outer sides of the belts, baffles are provided at both ends of the mixing barrel, the baffles are installed on the support frame by bolts, limiting blocks are embedded in the plurality of baffles, and one end of each of the limiting blocks is rotatably connected to a supporting ball, the outer side of the supporting ball extends to one end of the mixing barrel and contacts with the mixing barrel.

[0012] It can be seen that in the above technical solution, when the mixing barrel is placed between two adjacent supporting shafts, the two ends of the mixing barrel are respectively in contact with the supporting balls, so that the supporting balls can be stuck in the ends of the mixing barrel, which can not only rotate the mixing barrel but also drive the supporting balls to rotate on the limit blocks when the mixing barrel rotates, so as to ensure the stability of the mixing barrel when it rotates.

[0013] A method for preparing a high-temperature corrosion inhibitor for a distillation device comprises the following steps.

[0014] In step one, the staff installs the device at the designated location. When preparing the corrosion inhibitor, the staff passes the raw materials through the valve. The raw materials are transported to two groups of inner cavities through the valve. At the same time, the raw materials can be diverted through the partition of the mixing inclined rod in the inner cavity to avoid accumulation.

[0015] Step two, after the raw materials are added into the inner cavity, the mixing barrel is placed between two adjacent supporting shafts, which are lifted by the supporting shafts. At the same time, the servo motor is started, which drives the driving wheel to rotate, and then the belt rotates, which makes each driven wheel rotate. When the driven wheel rotates, it drives the supporting shaft to rotate. The rotation of the supporting shaft rubs against the mixing barrel, which makes the mixing barrel rotate. The rotation of the mixing barrel drives each inner cavity, screen and mixing inclined rod to rotate, so that the raw materials can be mixed in the inner cavity.

[0016] Step three, during the mixing of the raw materials in the inner cavity, the support frame is driven by a hydraulic rod to rotate along the axis point of the connection between the rotating shaft and the base through the rotating shaft, so that the support frame can swing in the base, shaking the raw materials when mixing in the inner cavity, thereby improving the mixing efficiency and effect.

[0017] Step four, when the high-temperature corrosion inhibitor is mixed and prepared in the mixing barrel, when the mixing barrel is placed between two adjacent supporting shafts, the two ends of the mixing barrel are respectively in contact with the supporting balls, so that the supporting balls can be stuck in the ends of the mixing barrel, which can not only rotate the mixing barrel but also drive the supporting balls to rotate on the limit blocks when the mixing barrel rotates, so as to ensure the stability of the mixing barrel when it rotates.

[0018] Step 5: When the high temperature corrosion inhibitor is prepared in the device, it passes through the temperature required by the temperature control box controller. After the preparation of the high temperature corrosion inhibitor is completed, the corresponding mixing cylinder is taken out from the protective box.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention allows the raw materials to pass through the valve and be transported to two groups of inner cavities through the valve. At the same time, the raw materials can also be diverted through the partition of the mixing inclined rod in the inner cavity to avoid accumulation;

[0021] 2. The present invention places the mixing barrel between two adjacent supporting shafts, and the supporting shafts lift the mixing barrel. The supporting shafts rotate and rub against the mixing barrel, thereby causing the mixing barrel to rotate. The rotation of the mixing barrel drives the rotation of each inner cavity, the screen and the mixing inclined rod, so that the raw materials can be mixed in the inner cavity;

[0022] 3. When the raw materials are mixed in the inner cavity of the present invention, the traction force generated by the rotation of the mixing barrel can also drive the vibration rod and the slider to slide on the slip ring, so that the vibration generated by the contact between the vibration rod and the inner cavity is transmitted to the inner cavity, and then the inner cavity generates high-frequency amplitude, thereby increasing the molecular movement speed in the mixture, promoting the mixing between different components, and improving the mass transfer efficiency;

[0023] To summarize, the support frame is driven by a hydraulic rod to rotate along the axis point of the connection between the rotating shaft and the base, so that the support frame can swing in the base, and the raw materials are shaken when they are mixed in the inner cavity, thereby improving the mixing efficiency and effect. When the support frame is tilted, each mixing barrel can be in a tilted state, which makes it easy to gather the raw materials together. Combined with the traction force when the mixing barrel rotates, the efficiency and effect of the corrosion inhibitor during preparation can be effectively ensured, and it is easy to make appropriate adjustments according to the amount of raw materials to avoid diffusion of the raw materials during mixing, thereby ensuring the effect of the chemical reaction and ensuring the generation of the required corrosion inhibitor intermediate or final product quality.

[0041] The protection box 2 is installed on the support frame 102 by bolts, and a plurality of support shafts 201 are arranged at the bottom of the inner cavity of the protection box 2. The plurality of support shafts 201 are installed on the support frame 102 by bearings, and a mixing barrel 202 is arranged between each two adjacent support shafts 201. A sealing cover 203 is inserted at one end of the mixing barrel 202.

A valve 205 is provided at one end, the two groups of inner cavities 204 are connected, and a screen 206 is clamped at one end of each inner cavity 204, and a mixing inclined rod 210 is inserted in the two groups of inner cavities 204. A slip ring 208 is fixedly provided at one end of the two groups of inner cavities 204 that are close to each other, and a slider 209 is slidably connected to each slip ring 208, and a vibration rod 207 is inserted on the slider 209, and the vibration rod 207 extends to the outside of the inner cavity 204.

[0042] A servo motor 3 is installed on one side of the bottom of the support frame 102 by bolts, and a driving wheel 301 is provided at the output end of the servo motor 3. A driven wheel 302 is fixedly provided at one end of multiple supporting shafts 201. Belts 303 are sleeved on the outer sides of the driving wheel 301 and the driven wheel 302. Several tensioning wheels installed on the support frame 102 are provided on the outer sides of the belts 303. Baffles 304 are provided at both ends of the mixing barrel 202. The baffles 304 are installed on the support frame 102 by bolts.

The outer side of the supporting ball 306 extends to one end of the mixing barrel 202 and contacts with the mixing barrel 202.

[0043] A method for preparing a high-temperature corrosion inhibitor for a distillation device comprises the following steps.

[0044] In step one, the staff installs the device at the designated location. When preparing the corrosion inhibitor, the staff passes the raw materials through the valve 205. The raw materials are transported to the two groups of inner cavities 204 through the valve 205. At the same time, the raw materials can also be diverted through the partition of the mixing inclined rod 210 in the inner cavity 204 to avoid accumulation.

[0045] Step 2, after the raw materials are added into the inner cavity 204, the mixing barrel 202 is placed between two adjacent supporting shafts 201, and the supporting shafts 201 hold it up, and at the same time, the servo motor 3 is started, the servo motor 3 drives the driving wheel 301 to rotate, and then the belt 303 rotates, so that each driven wheel 302 rotates, and when the driven wheel 302 rotates, it drives the supporting shaft 201 to rotate, and the supporting shaft 201 rotates and rubs against the mixing barrel 202, so that the mixing barrel 202 rotates, and the rotation of the mixing barrel 202 drives each inner cavity 204, the screen 206 and the mixing inclined rod 210 to rotate, so that the raw materials can be mixed in the inner cavity 204.

[0046] Step three, during the mixing of the raw materials in the inner cavity 204, the support frame 102 is driven by the hydraulic rod 104 to rotate along the axis point of the connection between the rotating shaft 103 and the base 1 through the rotating shaft 103, so that the support frame 102 can swing in the base 1, and shake the raw materials when mixing in the inner cavity 204, thereby improving the mixing efficiency and effect.

[0047] Step four, when the high-temperature corrosion inhibitor is mixed and prepared in the mixing barrel 202, when the mixing barrel 202 is placed between two adjacent supporting shafts 201, the two ends of the mixing barrel 202 are respectively in contact with the supporting balls 306, so that the supporting balls 306 can be stuck in the ends of the mixing barrel 202, which can not only support the mixing barrel 202 but also drive the supporting balls 306 to rotate on the limit blocks 305 when the mixing barrel 202 rotates, so as to ensure the stability of the mixing barrel 202 when rotating.

[0048] Step 5: When the high temperature corrosion inhibitor is prepared in the device, the temperature required by the temperature control box 101 controller is controlled. After the preparation of the high temperature corrosion inhibitor is completed, the corresponding mixing cylinder 202 is taken out from the protective box 2.

[0049] When in use according to the above structure, the raw materials are passed through the valve 205, and the raw materials are transported to the two groups of inner cavities 204 through the valve 205. At the same time, the raw materials can also be diverted through the partition of the mixing inclined rod 210 in the inner cavity 204. After the raw materials are added into the inner cavity 204, the mixing barrel 202 is placed between two adjacent supporting shafts 201, and the servo motor 3 is started to drive the driving wheel 301 to rotate so that the belt 303 drives the driven wheel 302 to rotate. When the driven wheel 302 rotates, it drives the supporting shaft 201 to rotate. The rotation of the supporting shaft 201 rubs against the mixing barrel 202, and then the mixing barrel 202 rotates. The rotation of the mixing barrel 202 drives each inner cavity 204, the screen 206 and the mixing inclined rod 210 to rotate, so that the raw materials can be mixed in the inner cavity 204.

[0050] The support frame 102 is driven by the hydraulic rod 104 to rotate along the axis point of the connection between the rotation shaft 103 and the base 1 through the rotation shaft 103, so that the support frame 102 can swing in the base 1. When the mixing barrel 202 is placed between two adjacent supporting shafts 201, the two ends of the mixing barrel 202 are respectively in contact with the support balls 306, so that the support balls 306 can be stuck at the ends of the mixing barrel 202 to ensure the stability of the mixing barrel 202 during rotation. After the temperature required by the controller of the temperature control box 101 is reached, the corresponding mixing barrel 202 is taken out of the protective box 2 after the preparation of the high-temperature corrosion inhibitor is completed.

[0051] Furthermore, when mixing with the raw materials in the inner cavity 204, the traction force generated by the rotation of the mixing barrel 202 can also drive the vibration rod 207 and the slider 209 to slide on the slip ring 208, so that the vibration generated by the contact between the vibration rod 207 and the inner cavity 204 is transmitted to the inner cavity 204, and then the inner cavity 204 generates high-frequency amplitude, thereby increasing the molecular movement speed in the mixture, promoting the mixing between different components, and improving the mass transfer efficiency.

[0052] Different from the prior art, the present application discloses a high-temperature corrosion inhibitor preparation device and method for a distillation device, in which a support frame 102 is driven by a hydraulic rod 104 to rotate along the axis point of the connection between the rotating shaft 103 and the base 1 through the rotating shaft 103, so that the support frame 102 can swing in the base 1, and shake the raw materials when they are mixed in the inner cavity 204, thereby improving the mixing efficiency and effect. When the support frame 102 is tilted, each mixing barrel 202 can be in a tilted state, which makes it easy to gather the raw materials together. Combined with the traction force when the mixing barrel 202 rotates, the efficiency and effect of the corrosion inhibitor during preparation can be effectively ensured, and it is easy to make appropriate adjustments according to the amount of raw materials to avoid diffusion of the raw materials during mixing, thereby ensuring the effect of the chemical reaction and ensuring the generation of the required corrosion inhibitor intermediate or final product quality.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
