Description

Technical Field

[0001] The invention relates to the technical field of electric desalination treatment, and in particular to a fully desalinated electric desalination treatment device and a use method thereof. Background Art

[0002] Electro-desalting is an important pretreatment process before crude oil enters distillation. It is mainly used to remove inorganic salts and water in crude oil to reduce the harm to subsequent processing. Electro-desalting is based on the principles of electrolysis and physical separation. By injecting a certain amount of fresh water and demulsifier into crude oil, the emulsified state in crude oil is destroyed, and tiny water droplets are aggregated into large water droplets. Under the action of the electric field, these large water droplets further aggregate and move toward the electrodes, and finally achieve oil-water separation under the action of gravity. The salt is dissolved in the water and discharged from the system with the water flow.

[0003] Electrodesalting is widely used in the oil refining industry and is an important process in crude oil processing. In addition, with the development of technology and the improvement of environmental protection requirements, electrodesalting is gradually being applied to water treatment processes in other fields, such as seawater desalination and industrial wastewater treatment.

[0004] In the prior art, in the process of using an electric desalter to electrically desalt crude oil, a certain amount of fresh water and a demulsifier need to be injected into the crude oil for sufficient mixing to destroy the emulsified state in the crude oil. Generally, a stirring structure is used to mix and stir the crude oil with the fresh water and the demulsifier. However, the existing stirring structure is not convenient for adjusting the stirring structure during use, which easily affects the mixing intensity between the crude oil, the fresh water and the demulsifier, thereby reducing the removal effect of inorganic salts and water in the crude oil. Therefore, it is necessary to propose a fully desalted electric desalting treatment equipment and a method of using the same to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide an electric desalination treatment device with sufficient desalination and a method of using the same to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A fully desalinated electric desalination treatment equipment and a use method thereof, comprising a tank body; a controller is fixedly installed at one end of the tank body, a commutator is fixedly installed inside the tank body, a fixed frame is fixedly installed inside the tank body on one side of the commutator, a rotating frame is rotatably installed on the other side of the fixed frame through a bearing, the output shaft of the commutator is fixedly connected to the surface of the other side of the rotating frame, a motor is fixedly installed on the top of the tank body, the output shaft of the motor extends to the inside of the tank body and is connected to the output shaft of the commutator, a plurality of gears are arranged inside the rotating frame, the periphery of each gear near both ends is fixedly connected to a bearing seat, both ends of each gear extend out of the interior of the rotating frame and are fixedly installed with a stirring plate, a rack is arranged inside the rotating frame at the bottom of each gear, the rack and each gear are meshed with each other, electric push rods are fixedly installed inside the rotating frame on both sides of the bottom of the rack, a connecting plate is fixedly installed on the inner surface of each electric push rod, and the top surface of each connecting plate is fixedly connected to the bottom of the rack.

[0008] The existing stirring structure is not easy to adjust during use, which easily affects the mixing strength between crude oil, fresh water and demulsifier, thereby reducing the removal effect of inorganic salts and water in crude oil. In the present application, an electric push rod is installed to drive the rack to move to one side or the other side. At the same time, the rack and the gear are meshed with each other, and the gear can be driven to rotate during the movement of the rack, so that the inclination angle of the stirring plate can be adjusted, thereby changing the flow path of crude oil, fresh water and demulsifier, reducing the mixing strength between crude oil, fresh water and demulsifier, preventing the generation of an emulsion that is difficult to break due to excessive mixing strength, and preventing insufficient mixing due to too weak mixing strength, thereby improving the desalination effect of electric crude oil.

[0009] A further improvement of the technical solution of the present invention is that: splints are provided on both sides of each gear, an anti-skid plate is attached to the inner surface of each splint, each anti-skid plate is made of rubber material, and a reinforcement component for adjusting the position of the splint is provided on the top of each gear.

[0010] The above-mentioned technical solution is adopted. In this solution, the stirring plate is limited only by the raised structure between the gear and the rack. If the resistance encountered by the stirring plate is too large, the raised structure between the gear and the rack is prone to deformation or damage, which may easily cause the gear to rotate again and affect the use of the stirring plate. In this application, the positions of the two clamping plates are adjusted by reinforcing components, so that the anti-slip plate fits tightly against the outer surface of the gear, which can limit the gear and thereby improve the stability of the stirring work of the stirring plate.

[0011] A further improvement of the technical solution of the present invention is that: an arc groove is formed on the inner surface of each anti-slip plate, and a plurality of convex strips are formed on the surface of each arc groove.

[0012] The above technical solution is adopted. In this solution, by setting the inner surface of the anti-skid plate to a special shape, after the anti-skid plate is tightly fitted with the outer surface of the gear, the convex strip can limit the tooth grooves on the outer surface of the gear, thereby further improving the stability of the stirring work of the stirring plate.

[0013] A further improvement of the technical solution of the present invention is that each reinforcement component includes a fixed plate, the top surface of each fixed plate is fixedly connected to the inner wall of the rotating frame, a bidirectional screw is rotatably installed inside each fixed plate through a bearing, a motor is fixedly installed on one side of each fixed plate, the output shaft of each motor extends to the interior of each fixed plate and is fixedly connected to the surface of one side of the bidirectional screw, a pair of sliders are threadedly installed on the outer surface of each bidirectional screw, and the bottom surface of each slider is fixedly connected to the top of each clamp.

[0014] The above technical solution is adopted. In this solution, a motor is installed to drive the bidirectional screw to rotate, and at the same time drive the two sliders to move inward respectively, so that the two clamps are close to each other, thereby making the anti-slip plate fit tightly with the outer surface of the gear.

[0015] A further improvement of the technical solution of the present invention is that a plurality of support rods are fixedly installed at the bottom of the rack inside each connecting plate.

[0016] The above-mentioned technical solution is adopted. In this solution, the rack is in a suspended state, and is only supported and limited by the electric push rod during the movement. After long-term use, the rack is prone to loosen to the bottom, thereby affecting the effect of gear rotation adjustment. In this application, the bottom of the rack can be supported by installing a support rod, thereby improving the stability of the rack sliding.

[0017] A further improvement of the technical solution of the present invention is that a second ball is rotatably mounted inside each support rod, and each second ball extends out of the inside of each support rod and fits against the inner wall of the rotating frame.

[0018] The above-mentioned technical solution is adopted. In this solution, the contact area between the bottom of the support rod and the inner wall of the rotating frame can be reduced by installing the second ball. When the support rod follows the movement of the rack, the second ball can roll along the inner wall of the rotating frame, thereby reducing the wear on the support rod and the inner wall of the rotating frame.

[0019] A further improvement of the technical solution of the present invention is that a plurality of first balls are rollingly mounted inside each connecting plate, and each first ball extends out of the inside of each connecting plate and fits against the inner wall of the rotating frame.

[0020] By adopting the above technical solution, the contact area between the bottom of the connecting plate and the inner wall of the rotating frame can be reduced by installing the first ball. In the process of the electric push rod pushing the connecting plate to move, the first ball can roll along the inner wall of the rotating frame, thereby reducing the wear on the connecting plate and the inner wall of the rotating frame.

[0021] The present invention also provides a method for using an electric desalination treatment device for sufficient desalination, comprising the following steps:

[0022] S1. Preliminary preparation process: the operator first injects a certain amount of fresh water and demulsifier into the tank containing crude oil;

[0023] S2, mixing process, the operator starts the motor again, uses the commutator to drive the rotating frame to rotate, and uses the stirring plate to mix and stir the liquid inside the tank, so that the crude oil, fresh water and demulsifier are fully mixed;

[0024] S3, adjustment process, when the operator detects with the help of external equipment that the mixing intensity between crude oil, fresh water and demulsifier is too high, the operator controls the electric push rod to drive the rack to move, and at the same time drives the gear to rotate, and adjusts the angle of the stirring plate, thereby changing the flow path of crude oil, fresh water and demulsifier, thereby reducing the mixing intensity between crude oil, fresh water and demulsifier;

[0025] S4, reinforcement process, when the gear stops rotating, the operator controls the motor to drive the bidirectional screw to rotate, and at the same time drives the slider and the clamping plate to approach the gear, and then uses the anti-skid plate to clamp and reinforce the gear to prevent the gear from rotating when the stirring plate collides between the crude oil, fresh water and demulsifier.

[0026] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0027] 1. The present invention provides an electric desalting treatment device with full desalination and a method for using the same. The electric push rod can drive the rack to move to one side or the other side. At the same time, through the cooperation between the rack and the gear, the rack can drive the gear to rotate when it moves, so as to adjust the inclination angle of the stirring plate, thereby changing the flow path of crude oil, fresh fresh water and demulsifier, reducing the mixing intensity between crude oil, fresh fresh water and demulsifier, preventing the generation of an emulsion that is difficult to break due to excessive mixing intensity, and preventing insufficient mixing due to too weak mixing intensity, thereby improving the desalting effect of the electric crude oil.

[0028] 2. The present invention provides an electric desalination treatment equipment with full desalination and a method for using the same. Through the cooperation between the reinforcement components and the clamping plates, the anti-slip plate can be closely fitted to the outer surface of the gear, and the gear can be limited to prevent the gear from rotating when the stirring plate collides between the crude oil, fresh water and demulsifier, thereby improving the stability of the stirring work of the stirring plate.

[0029] 3. The present invention provides an electric desalination treatment device with full desalination and a method of using the same. By setting the inner surface of the anti-slip plate into a special shape, the convex strips can limit the tooth grooves on the outer surface of the gear, thereby further improving the stability of the stirring work of the stirring plate.

[0043] In this embodiment, the existing stirring structure is not convenient to adjust during use, which easily affects the mixing strength between crude oil, fresh fresh water and demulsifier, thereby reducing the removal effect of inorganic salts and water in crude oil. In this application, the electric push rod 13 is installed to drive the rack 12 to move to one side or the other side. At the same time, the rack 12 is meshed with the gear 6, and the gear 6 can be driven to rotate during the movement of the rack 12, so that the inclination angle of the stirring plate 9 can be adjusted, thereby changing the flow path of the crude oil, fresh fresh water and demulsifier, reducing the mixing strength between the crude oil, fresh fresh water and demulsifier, preventing the production of an emulsion that is difficult to break due to excessive mixing strength, and preventing insufficient mixing due to too weak mixing strength, thereby improving the desalination effect of the electric crude oil.

[0044] Example 2

[0045] like Figure 3 , Figure 6 and Figure 7As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, each gear 6 is provided with a splint 7 on both sides, and an anti-skid plate 8 is attached to the inner surface of each splint 7, and the material of each anti-skid plate 8 is rubber material, and a reinforcing component 5 for adjusting the position of the splint 7 is provided on the top of each gear 6, and an arc groove is provided on the inner surface of each anti-skid plate 8, and a plurality of convex strips are provided on the surface of each arc groove, and each reinforcing component 5 includes a fixed plate 501, and the top surface of each fixed plate 501 is fixedly connected to the inner wall of the rotating frame 3, and a bidirectional screw rod 502 is rotatably installed inside each fixed plate 501 through a bearing, and a motor 503 is fixedly installed on one side of each fixed plate 501, and the output shaft of each motor 503 extends to the inside of each fixed plate 501 and is fixedly connected to the surface of one side of the bidirectional screw rod 502, and a pair of sliders 504 are threadedly installed on the outer surface of each bidirectional screw rod 502, and the bottom surface of each slider 504 is fixedly connected to the top of each splint 7.

[0046] In this embodiment, the stirring plate 9 is limited only by the raised structure between the gear 6 and the rack 12. If the resistance to the stirring plate 9 is too large, the raised structure between the gear 6 and the rack 12 is prone to deformation or damage, which may easily cause the gear 6 to rotate again, affecting the use of the stirring plate 9. In this application, the positions of the two clamping plates 7 are adjusted by the reinforcement component 5, so that the anti-skid plate 8 is tightly fitted with the outer surface of the gear 6, which can limit the gear 6 and thus improve the stability of the stirring work of the stirring plate 9; by setting the inner surface of the anti-skid plate 8 to a special shape, after the anti-skid plate 8 is tightly fitted with the outer surface of the gear 6, the raised strip can limit the tooth groove on the outer surface of the gear 6, thereby further improving the stability of the stirring work of the stirring plate 9; by installing the motor 503, the bidirectional screw 502 can be driven to rotate, and at the same time, the two sliders 504 are driven to move inward respectively, so that the two clamping plates 7 are close to each other, thereby making the anti-skid plate 8 and the outer surface of the gear 6 tightly fit.

[0047] Example 3

[0048] like Figure 4 , Figure 5 and Figure 6 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, a plurality of support rods 16 are fixedly installed at the bottom of the rack 12 on the inner side of each connecting plate 15, and a second ball 18 is rollingly installed inside each support rod 16, and each second ball 18 extends out of the interior of each support rod 16 and fits against the inner wall of the rotating frame 3, and a plurality of first balls 17 are rollingly installed inside each connecting plate 15, and each first ball 17 extends out of the interior of each connecting plate 15 and fits against the inner wall of the rotating frame 3.

[0049] In the present embodiment, the rack 12 is in a suspended state, and is only supported and limited by the electric push rod 13 during the movement. After long-term use, the rack 12 is easy to loosen toward the bottom, thereby affecting the effect of rotation adjustment of the gear 6. In the present application, the bottom of the rack 12 can be supported by installing the support rod 16, thereby improving the sliding stability of the rack 12, and the contact area between the bottom of the support rod 16 and the inner wall of the rotating frame 3 can be reduced by installing the second ball 18. In the process of the support rod 16 following the movement of the rack 12, the second ball 18 can roll along the inner wall of the rotating frame 3, thereby reducing the wear on the support rod 16 and the inner wall of the rotating frame 3; by installing the first ball 17, the contact area between the bottom of the connecting plate 15 and the inner wall of the rotating frame 3 can be reduced. In the process of the electric push rod 13 pushing the connecting plate 15 to move, the first ball 17 can roll along the inner wall of the rotating frame 3, thereby reducing the wear on the connecting plate 15 and the inner wall of the rotating frame 3.

[0050] The present invention also provides a method for using an electric desalination treatment device for sufficient desalination, comprising the following steps:

[0051] S1, preparatory process, the operator first injects a certain amount of fresh water and demulsifier into the tank 1 containing crude oil;

[0052] S2, mixing process, the operator starts the motor 2 again, uses the commutator 10 to drive the rotating frame 3 to rotate, and uses the stirring plate 9 to mix and stir the liquid inside the tank body 1, so that the crude oil, fresh water and demulsifier are fully mixed;

[0053] S3, adjustment process, when the operator detects that the intensity of the mixture between the crude oil, fresh water and demulsifier is too high with the help of external equipment, the operator controls the electric push rod 13 to drive the rack 12 to move, and drives the gear 6 to rotate, and adjusts the angle of the stirring plate 9, thereby changing the flow path of the crude oil, fresh water and demulsifier, and then reducing the intensity of the mixture between the crude oil, fresh water and demulsifier;

[0054] S4, reinforcement process, when the gear 6 stops rotating, the operator controls the motor 503 to drive the bidirectional screw 502 to rotate, and at the same time drives the slider 504 and the clamping plate 7 to approach the gear 6, and then uses the anti-slip plate 8 to clamp and reinforce the gear 6 to prevent the stirring plate 9 from driving the gear 6 to rotate when the collision occurs between the crude oil, fresh water and demulsifier.

[0055] The working principle of the fully desalinated electrical desalination treatment equipment and its use method are described in detail below.

[0056] like Figure 1-Figure 8As shown, the operator injects a certain amount of fresh water and demulsifier into the tank 1 containing crude oil, then starts the motor 2, and uses the commutator 10 to reverse the output shaft of the motor 2, thereby driving the rotating frame 3 and the stirring plate 9 to rotate, and the crude oil, fresh water and demulsifier in the tank 1 are mixed and stirred to make them fully mixed. During the stirring process, the operator can use external equipment to detect the mixing intensity between the crude oil, fresh water and demulsifier. If it is detected that the mixing intensity is too high, the operator can temporarily turn off the motor 2 to stop the rotating frame 3, and then control the electric push rod 13 to drive the rack 12 to move, thereby driving the gear 6 to rotate, and stirring the stirring plate 9. After the adjustment is completed, the operator controls the motor 503 to drive the bidirectional screw 502 to rotate, thereby driving the slider 504 and the clamping plate 7 to approach the gear 6, so that the anti-skid plate 8 limits and reinforces the gear 6 to prevent the stirring plate 9 from driving the gear 6 to rotate when a collision occurs between the crude oil, fresh fresh water and the demulsifier, thereby changing the flow paths of the crude oil, fresh fresh water and the demulsifier, and reducing the mixing intensity between the crude oil, fresh fresh water and the demulsifier. If it is detected that the mixing intensity is too low, the electric push rod 13 can also be controlled to drive the rack 12 to move in the opposite direction, thereby driving the gear 6 to rotate in the opposite direction, and changing the flow paths of the crude oil, fresh fresh water and the demulsifier again.

[0057] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
