Abstract

This invention belongs to the field of demulsifier production technology, and specifically relates to a demulsifier production equipment and its preparation method. The equipment includes a reaction vessel and a jacket disposed on the outer wall of the reaction vessel. The side wall of the jacket is connected to an inlet pipe and an outlet pipe. The upper side wall of the reaction vessel is connected to multiple injection pipes, and the lower side wall is connected to a discharge pipe. When the viscosity of the demulsifier raw material is detected to be low, the variable blade assembly horizontally pushes the raw material through the surface stirring plate, causing the demulsifier raw material to flow rapidly within the reaction vessel, thereby quickly achieving a mixing effect. When the viscosity of the demulsifier raw material is detected to be high, the variable blade assembly deforms into a ribbon-type stirring paddle, which can propel the demulsifier along the axial and circumferential directions. The large axial thrust generated can overcome the viscous resistance of the high-viscosity demulsifier, causing the demulsifier to tumble up and down.

Description

Technical Field

[0001] This invention belongs to the field of demulsifier production technology, and in particular relates to a demulsifier production equipment and its preparation method. Background Technology

[0002] Demulsifiers have stronger surface activity than emulsifiers in emulsions. For water-in-oil emulsions, demulsifier molecules can quickly penetrate to the oil-water interface and replace the original emulsifier molecules. The structural characteristics of demulsifier molecules enable them to reduce the interfacial tension between oil and water. At the same time, through flocculation and aggregation, small oil droplets collide and combine with each other to form large oil droplets, thereby achieving oil-water separation. For oil-in-water emulsions, the principle is similar. Demulsifiers promote the aggregation of small water droplets into large water droplets, which are eventually separated from the oil phase.

[0003] In the production process of demulsifiers, a reaction vessel is needed to mix the raw materials to ensure the smooth progress of the reaction. For example, a petroleum demulsifier reaction vessel is proposed in patent publication number CN207913754U.

[0004] Due to varying production needs, different raw materials are required to prepare demulsifiers. The viscosity of demulsifiers mixed with different raw materials varies (for example, the viscosity of the acrylic acid-triethanolamine-concentrated sulfuric acid system demulsifier is higher than that of the ethylene oxide-propylene oxide system demulsifier). Therefore, different types of agitators must be selected based on the viscosity of the demulsifier. For instance, when mixing high-viscosity demulsifier raw materials, a ribbon agitator should be used. This type of agitator, during rotation, acts like a screw conveyor, propelling the demulsifier along both the axial and circumferential directions. The large axial thrust it generates can overcome... The viscous resistance of high-viscosity demulsifiers causes them to tumble up and down. However, for the mixing of low-viscosity demulsifier raw materials, a paddle mixer is required because low-viscosity demulsifiers have good fluidity. The horizontal pushing action of the paddle mixer can effectively drive the demulsifier to flow in the reactor or container, thereby achieving a rapid mixing effect. If the operator selects the wrong mixer, the wrong mixer can easily damage the molecular structure of the demulsifier and lead to problems such as uneven mixing and low mixing efficiency. Moreover, using a mixer with multiple different blades will increase the cost of equipment and occupy a large space.

[0005] To address these issues, a demulsifier production equipment and preparation method are proposed. Summary of the Invention

[0010] Preferably, the variable blade assembly includes an adjusting tube and a piston block. The piston block is slidably disposed inside the adjusting tube. The adjusting tube is connected to the mounting tube. A retaining ring is fixedly connected to the inner wall of the adjusting tube. The piston block is connected to the retaining ring via a spring. An electrically controlled valve is disposed inside the adjusting tube. An adjusting rod is rotatably connected to the side wall of the piston block away from the electrically controlled valve.

[0013] Preferably, the outer walls of the plurality of diverter tubes are fixedly fitted with a plurality of heat dissipation rings, and the side walls of the heat dissipation rings are provided with a plurality of heat dissipation holes.

[0014] A method for preparing a demulsifier includes the following steps: S1. The demulsifier raw material is delivered into the reactor through multiple injection pipes, and then the stirring motor is controlled by the control switch. S2. The stirring motor controls the rotation of the viscosity sensing component through the gear ring transmission assembly. The viscosity sensing component drives the variable blade assembly to rotate through the temperature control assembly to stir the raw materials. While stirring the demulsifier raw materials, the temperature control assembly heats or cools the raw materials from the outside and inside. The temperature-sensing mixing assembly can also automatically adjust the temperature of areas with uneven temperature. S3, the PLC controller controls the deformation and combination of the variable blade assembly according to the electrical signal transmitted by the viscosity sensing component to stir the demulsifier raw material; S4. Finally, open the control valve to discharge all the mixed demulsifier raw materials through the discharge pipe.

[0015] Compared with existing technologies, the advantages of a demulsifier production equipment and its preparation method are as follows: By configuring a reactor, jacket, inlet pipe, outlet pipe, injection pipe, discharge pipe, control valve, upper transfer pipe, control switch, PLC controller, stirring motor, tee connector, liquid inlet pipe, first control valve, lower transfer pipe, bend, first regulating valve, viscosity sensing component, temperature control component, and variable blade assembly, the viscosity of the demulsifier raw material can be detected during the stirring process after it is delivered to the reactor. When the detected viscosity of the demulsifier raw material is low, the variable blade assembly will horizontally push the raw material through the surface stirring plate. The demulsifier raw material flows rapidly within the reactor, achieving a quick mixing effect. When the viscosity of the demulsifier raw material is detected to be high, the variable blade assembly is deformed to form a ribbon agitator, which propels the demulsifier to move axially and circumferentially. The large axial thrust generated can overcome the viscous resistance of the high-viscosity demulsifier, causing the demulsifier to tumble up and down. Furthermore, the combined ribbon agitator adheres to the inner wall of the reactor, thereby driving the material near the reactor wall to flow rapidly. This ensures that the material near the wall is constantly renewed, and the new material comes into contact with the wall, enabling more efficient heat exchange.

[0016] By using the temperature control components, the temperature of the raw materials inside the reactor can be adjusted from the outside to the inside through the jacket, and the temperature can also be adjusted from the inside. This not only improves the speed of temperature adjustment, but also makes the temperature adjustment inside the reactor more synchronized, ensuring the consistency of the demulsifier raw material reaction rate.

[0017] By using the temperature-sensing mixing component, the temperature of the raw materials in different areas can be detected when adjusting the temperature of the demulsifier raw materials in the reactor. If the detection finds that the temperature of some raw materials has not reached the preset temperature within a specified time, the raw materials in that area can be extracted separately, their temperature adjusted, and then transported back into the reactor for stirring, thus further ensuring the quality of the demulsifier product.

An upper rotating pipe 8 is rotatably connected to the upper side wall of the reactor 1 via a sealed bearing. The upper end of the upper rotating pipe 8 extends out of the wall of the reactor 1 and is connected to a viscosity sensing component 18. A control switch 9 and a PLC controller 10 are fixedly connected to the right side wall of the reactor 1. The viscosity sensing component 18 includes a cylinder 181 and two connecting plates 182. A stirring motor 11 is connected to the cylinder 181 via a gear ring transmission assembly. 1. Transmission connection: The upper end of the upper rotating tube 8 passes through the cylinder 181 and is rotatably connected to the cylinder 181 via a bearing. Two connecting plates 182 are fixedly connected to the inner walls of the left and right sides of the cylinder 181, respectively. Two support plates 19 are symmetrically fixedly connected to the tube wall of the upper rotating tube 8 inside the cylinder 181. The same spring is fixedly connected between the support plates 19 and the connecting plates 182. A conductive block 20 is fixedly connected to the rear side wall of the rear support plate 19. The conductive block 20 is electrically connected to an external power source. An arc-shaped conductive plate 21 is embedded in the inner wall of the cylinder 181. The arc-shaped conductive plate 21 is electrically connected to the PLC controller 10. While stirring the raw materials inside the reactor 1, the viscosity of the raw materials can be detected. (Further details omitted) The stirring motor 11 is connected to the viscosity sensing component 18 via a gear ring transmission assembly. The three-way connector 12 is rotatably connected to the upper end of the upper rotating pipe 8 through a sealed bearing. The left port of the three-way connector 12 is fixedly connected to the liquid inlet pipe 13, and the liquid inlet pipe 13 is equipped with a first control valve 14. Temperature control assembly 22 is fixedly connected to the lower end of upper rotating pipe 8. The lower end of temperature control assembly 22 is connected to lower rotating pipe 15. A bent pipe 16 is fixedly connected to the lower side wall of reactor 1. The left end of bent pipe 16 is located inside reactor 1 and is rotatably connected to the lower end of lower rotating pipe 15 through a sealed bearing. The end of bent pipe 16 away from lower rotating pipe 15 is connected to the right side wall of jacket 2. A first regulating valve 17 is provided inside bent pipe 16. Temperature control assembly 22 includes upper horizontal pipe 221 and multiple branch pipes 222. Upper horizontal pipe 221 is fixedly connected to the lower end of upper rotating pipe 8. The upper ends of multiple branch pipes 222 are all connected to the lower side wall of upper horizontal pipe 221. The upper end of lower rotating pipe 15 is fixedly connected to lower horizontal pipe. 23. Both ends of the upper horizontal pipe 221 and the lower horizontal pipe 23 are sealed. The lower ends of multiple diversion pipes 222 are connected to the upper side wall of the lower horizontal pipe 23. The upper horizontal pipe 221 and the lower horizontal pipe 23 are fixedly connected by the same installation pipe 24. The inner diameter of the installation pipe 24 and the diversion pipe 222 is smaller than the inner diameter of the upper rotating pipe 8 and the lower rotating pipe 15. When adjusting the temperature of the raw material inside the reactor 1, the temperature of the raw material can be adjusted from the outside to the inside through the jacket 2, and the temperature of the raw material can be adjusted from the inside at the same time. This not only improves the speed of temperature adjustment, but also makes the temperature adjustment inside the reactor 1 more synchronous, ensuring the consistency of the reaction rate of the demulsifier raw material. Multiple variable blade assemblies 25 are evenly distributed on the surface of the temperature control assembly 22. The viscosity sensing assembly 18 is electrically connected to the multiple variable blade assemblies 25 via a PLC controller 10. Each variable blade assembly 25 includes an adjusting tube 251 and a piston block 252. The piston block 252 is slidably disposed within the adjusting tube 251. The adjusting tube 251 is connected to the mounting tube 24. A retaining ring 26 is fixedly connected to the inner wall of the adjusting tube 251. The piston block 252 is connected to the retaining ring 26 via a spring. An electrically controlled valve 27 is provided inside the adjusting tube 251. An adjusting rod 28 is rotatably connected to the side wall of the piston block 252 away from the electrically controlled valve 27. The adjusting rod 28 extends out of one end of the adjusting tube 251. The device is fixedly connected with segmented propeller blades 29. Each of the two adjacent segmented propeller blades 29 has a matching groove at one end. Multiple stirring plates 30 are fixedly connected to the upper surface of the segmented propeller blades 29. A limit pin 31 is fixedly connected to the end of the regulating pipe 251 away from the mounting pipe 24. A straight groove 32 is opened on the rod wall of the regulating rod 28, which slides with the limit pin 31. An arc groove 33 is opened on the rod wall of the regulating rod 28 near the piston block 252. The straight groove 32 and the arc groove 33 are interconnected. The stirring plates 30 can be used to stir low-viscosity demulsifier raw materials, or they can be combined into a ribbon stirring paddle to stir high-viscosity demulsifiers. Multiple temperature-sensing mixing components 34 are evenly distributed on the surface of the temperature-regulating component 22 to detect and treat areas of uneven raw material temperature within the reactor 1. Each temperature-sensing mixing component 34 includes a temperature-sensing tube 341 and multiple short tubes 342. The temperature-sensing tube 341 is connected to the mounting tube 24, and the end of the temperature-sensing tube 341 away from the mounting tube 24 is closed. Each of the multiple short tubes 342 is connected to the wall of the temperature-sensing tube 341. A magnetic control valve 35 is installed inside each short tube 342. A temperature-sensing probe 36 is fixedly connected to the wall of the temperature-sensing tube 341 near the wall of the short tube 342. The temperature-sensing probe 36 is electrically connected to the corresponding magnetic control valve 35 via a PLC controller 10. A delivery pump 3 is fixedly connected to the outer right wall of the jacket 2. 7. The feed end of the conveying pump 37 is connected to the bend 16, and a second regulating valve 38 is provided inside the feed end of the conveying pump 37. A spiral tube 39 is fixedly sleeved on the outer wall of the reactor 1. The upper end of the spiral tube 39 is connected to the reactor 1, and the discharge end of the conveying pump 37 is connected to the lower end of the spiral tube 39. When adjusting the temperature of the demulsifier raw material in the reactor 1, the temperature of the raw material in different areas can be detected. When it is detected that the temperature of some raw materials has not reached the preset temperature within a specified time, the raw material in that area can be extracted separately and its temperature adjusted, and then transported back into the reactor 1 for stirring, which further ensures the quality of the demulsifier product.

[0022] A high-pressure air pump 40 is fixedly connected to the upper side wall of the reactor 1. The outlet of the high-pressure air pump 40 is connected to the right port of the three-way connector 12. A second control valve 41 is provided inside the outlet of the high-pressure air pump 40. A protective cover 42 covering the outside of the high-pressure air pump 40 is fixedly connected to the upper side wall of the reactor 1. The left end of the liquid inlet pipe 13 passes through the protective cover 42. A vent 43 is provided on the side wall of the protective cover 42, which can discharge the temperature regulating medium used for temperature regulation inside the temperature regulating component 22.

[0023] Multiple heat dissipation rings 44 are fixedly sleeved on the outer wall of multiple distribution pipes 222. Multiple heat dissipation holes 45 are opened on the side wall of the heat dissipation rings 44, which increases the contact area between the distribution pipes 222 and the demulsifier raw materials.

[0024] The operating principle of this invention is explained as follows: The demulsifier raw material is injected into the reaction vessel 1 through the injection pipe 5. Then, the operator sends a start signal to the PLC controller 10 through the control switch 9. After receiving the electrical signal, the PLC controller 10 first controls the opening of the first control valve 14 and the first regulating valve 17, and then delivers the temperature regulating medium to the inlet pipe 13 through an external pumping device. If it is necessary to heat the demulsifier raw material, hot water is delivered to the inlet pipe 13 through the external pumping device. The hot water is then delivered to the upper transfer pipe 8 through the three-way connector 12, and then to the upper horizontal pipe 221 through the upper transfer pipe 8. Then, the hot water is transported through the upper horizontal pipe 221 to the installation pipe 24 and multiple branch pipes 222. The heat in the hot water will dissipate to the surrounding raw materials through the installation pipe 24, branch pipes 222, and the heat dissipation ring 44 on the surface of the branch pipes 222, so that the raw materials are heated from the inside. The hot water inside the installation pipe 24 and branch pipes 222 will flow into the lower horizontal pipe 23 and be transported to the jacket 2 through the bend pipe 16. Finally, it will be discharged from the jacket 2 through the outlet pipe 4. At the same time, the external pumping equipment will transport the hot water from the inlet pipe 3 to the jacket 2 to heat the raw materials inside the reactor 1 from the outside. The hot water after use will also be discharged through the outlet pipe 4. Next, the PLC controller 10 controls the stirring motor 11 to operate at a relatively low speed (the low speed is preset by the PLC controller 10). The stirring motor 11 drives the cylinder 181 to rotate through the gear and ring gear transmission assembly (the gear and ring gear transmission assembly includes a gear fixedly connected to the output end of the stirring motor 11, and a ring gear fixedly sleeved on the outer wall of the cylinder 181, the gear and the ring gear meshing with each other). The connecting plate 182 on the inner wall of the cylinder 181 will compress the spring between it and the support plate 19. The elastic force of the spring compresses the support plate 19 and the upper rotating tube 8, thereby driving the upper rotating tube 8 to rotate. The upper rotating tube 8 will drive multiple adjusting tubes 251 to rotate through the upper horizontal tube 221 and the mounting tube 24. The adjusting tubes 251 drive multiple segmented propeller blades 29 to rotate through the adjusting rod 28. The segmented propeller blades 29 are initially in a position where... In a horizontal state, the segmented propeller blades 29 stir the demulsifier raw material through multiple stirring plates 30 on the upper surface. When the viscosity of the demulsifier raw material is low, the stirring plates 30 experience less resistance during stirring. This allows the spring between the connecting plate 182 and the support plate 19 to only need to be squeezed for a small stroke to have sufficient elasticity to push the upper rotating tube 8 to rotate the segmented propeller blades 29 and the stirring plates 30. The conductive block 20 and the arc-shaped conductive plate 21 will not contact each other. When the PLC controller 10 does not receive an electrical signal from the arc-shaped conductive plate 21 within a set time, the PLC controller 10 will control the stirring motor 11 to drive the stirring plate 30 to rotate at a high speed (the high speed is preset by the PLC controller 10), so that the demulsifier raw material flows rapidly in the reactor 1, thereby quickly achieving a mixing effect. Conversely, when the viscosity of the demulsifier raw material in reactor 1 is high, the stirring plate 30 experiences greater resistance during stirring. Following the aforementioned principle, the conductive block 20 will contact the arc-shaped conductive plate 21. The conductive block 20 is electrically connected to an external power source, and the arc-shaped conductive plate 21 is electrically connected to the PLC controller 10. When the conductive block 20 contacts the arc-shaped conductive plate 21, it sends an electrical signal to the PLC controller 10. Upon receiving this signal, the PLC controller 10 will open all the electrically controlled valves 27 inside the regulating pipes 251 and close the first regulating valve 17. The hot water supplied to the installation pipe 24 by the external pumping equipment will then be delivered to the regulating rod 28 through the electrically controlled valve 27, increasing the water pressure in the space near the electrically controlled valve 27 on the piston block 252. This causes the piston block 252 to overcome the spring's resistance. The force drives the adjusting rod 28 to move outward, which in turn drives the segmented propeller blades 29 to move outward as well. During the movement of the adjusting rod 28, the limiting pin 31 slides within the straight groove 32. When the segmented propeller blades 29 move to the set position, the limiting pin 31 slides through the straight groove 32 into the arc-shaped groove 33. The adjusting rod 28 is rotatably connected to the piston block 252. After the limiting pin 31 slides into the arc-shaped groove 33, the mutual pressing action between the arc-shaped surface of the arc-shaped groove 33 and the limiting pin 31 controls the adjusting rod 28 to drive the segmented propeller blades 29 to rotate. Since the ends of two adjacent segmented propeller blades 29 are provided with matching slots, multiple segmented propeller blades 29 will combine into a ribbon-type agitator after rotating to the set angle (the shape of the ribbon-type agitator is shown in the figure). Figure 4 After the demulsifier is prepared, the PLC controller 10 will control multiple electrically controlled valves 27 to open. At this time, there is no temperature regulating medium in the installation tube 24. After the electrically controlled valve 27 is opened, the spring between the piston block 252 and the retaining ring 26 will pull the piston block 252 to move closer to the retaining ring 26, thereby discharging the temperature regulating medium in the regulating tube 251. During the retraction process, the segmented propeller blades 29 will rotate to a horizontal angle under the interaction of the limiting pin 31 and the arc groove 33. At this time, each segmented propeller blade 29 will contact the inner wall of the reactor 1. During the rotation, it can drive the material near the reactor wall to flow quickly, so that the material near the wall is constantly renewed. New material contacts the wall, which can carry out heat exchange more efficiently. When the segmented propeller blade 29 comes into contact with the interior of the reactor 1, the segmented propeller blade 29, under the pressure of the inner wall of the reactor 1, will control the regulating rod 28 and the piston block 252 to stop moving, thereby causing the water pressure on the left side of the piston block 252 and the water pressure inside the mounting pipe 24 to continuously increase. When the water pressure detector in the external pumping equipment detects that the water pressure inside the mounting pipe 24 has reached the set value, it will send an electrical signal to the PLC controller 10. The PLC controller 10 will then control multiple electrically controlled valves 27 to close and control the first regulating valve 17 to open. At the same time, it will control the stirring motor 11 to drive the ribbon stirring paddle to rotate at a slower speed, which can push the demulsifier to move along the axial and circumferential directions. The large axial thrust generated can overcome the viscous resistance of the high-viscosity demulsifier and cause the demulsifier to tumble up and down. When reactor 1 is heated to the set time, PLC controller 10 will control the external pumping equipment to stop supplying the temperature regulating medium into the inlet pipe 13 and close the first control valve 14. Then, PLC controller 10 will control the high-pressure air pump 40 and the second control valve 41 to work simultaneously for the set time. The high-pressure air pump 40 will supply external gas through the three-way connector 12 to the upper rotating pipe 8 and the temperature regulating component 22, so that the remaining hot water inside the upper rotating pipe 8 and the temperature regulating component 22 will be completely supplied into the jacket 2 through the lower rotating pipe 15 and the bend 16. After the operating time of the second control valve 41 is reached, the PLC controller 10 will control the high-pressure air pump 40 to stop working and control the second control valve 41 to close. Then, the PLC controller 10 will control multiple temperature sensors 36 to work (at this time, the temperature sensing tube 341 is still rotating under the drive of the mounting tube 24). When the temperature sensor 36 detects that the temperature of some raw materials has not reached the set temperature (for example, after heating for the set time, the temperature of all raw materials should be at 100°C), when a certain temperature sensor 36 is rotating, it will detect... If the temperature of the raw materials in certain areas does not reach the preset value, the PLC controller 10 will control the magnetic valve 35 corresponding to the temperature sensor 36 to open, and control the second regulating valve 38 to open. At the same time, it will control the delivery pump 37 to work. The delivery pump 37 will first deliver the gas in the installation pipe 24, the lower transfer pipe 15, and the bend pipe 16 through the spiral pipe 39 to the reactor 1 (a one-way valve is provided at the upper end of the spiral pipe 39, not shown in the figure, to prevent the demulsifier raw material from entering the spiral pipe 39), thereby allowing the gas in the installation pipe 24, the lower transfer pipe 15, and the bend pipe 16 to pass through the spiral pipe 39. Under negative pressure, raw materials that have not reached the preset temperature value will be transported to the spiral tube 39 through the short pipe 342, installation pipe 24, lower transfer pipe 15 and bend pipe 16. At this time, hot water is still transported in the jacket 2. The hot water can be used to heat the raw materials in the spiral tube 39 that have not reached the standard temperature. After being fully heated, the raw materials will be transported back to the reactor 1 through the upper end of the spiral tube 39. This will minimize the problem of inconsistent reaction rates of the demulsifier raw materials due to local temperature differences, which would affect the quality of the demulsifier product.

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.
