Description

Technical Field

[0001] The present invention relates to the technical field of reactor raw material oil gun control, and in particular to a reactor raw material oil gun atomization mode remote monitoring automatic control device and method thereof. Background Art

[0002] The atomization mode of the raw material oil gun for the hard line of the carbon black reactor, and the angle of the spray atomization of the oil gun when it is sprayed into the throat section of the reactor directly affect the performance indicators of the carbon black product, such as the sieve residue and the carbon black product yield. Therefore, the fuel oil is refluxed and the combustion of the reactor is temporarily stopped during the production operation. The atomization circular cross-section area of ​​the raw material oil gun at the throat of the furnace is clearly observed through the sight glass window of the reactor door panel. The insertion depth of the oil gun, the atomization angle of the crude oil, and the use of the oil gun nozzle are manually tracked and observed, and corresponding adjustment measures are taken. The above-mentioned existing technology has the following defects in the observation method of the atomization mode of the raw material oil gun for the hard line of the carbon black reactor: Disadvantage 1. The main problem is the airflow after fuel oil combustion. During normal production, the high-temperature hot airflow completely blocks the observable scene of crude oil injection into the throat section and the atomization angle of the oil gun. The fuel combustion airflow must be cut off to fully display the crude oil injection state. Cutting off the fuel oil bypass return flow is a manual operation on site.

[0003] Disadvantage 2: When the operator observes the deep diameter layout scene in the reactor with his eyes, the position and angle of the person's standing will directly affect the judgment of the atomization degree. There is a lack of unified standard angle and direction as a basis and standard, and it is impossible to achieve consistent standards through manual labor.

[0004] To this end, we have designed a remote monitoring automatic control device and method for the atomization mode of the raw material oil gun of the reactor to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the control of the atomization mode of the raw oil gun of the reactor depends on the specific time of the operator, and the two people assist each other in monitoring the operation on site, which affects the operation of the equipment, and there is a lack of unified standard angles and directions for judging the degree of atomization as a basis and standard. A remote monitoring automatic control device and method for the atomization mode of the raw oil gun of the reactor are proposed. The reflux function is realized by opening and closing the automatic control valve, and the automatic rapid control function is realized, which completely replaces manual control and realizes intelligent automatic control. The image of the atomization image area is extracted by the monitoring mechanism, and the judgment standard of the atomization degree is unified.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A remote monitoring and automatic control device for the atomization mode of a raw oil gun of a reactor is provided.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The observation method of the atomization pattern of the raw material oil gun of the carbon black reactor hard line in the prior art is as follows: After contacting the central control operator through the intercom, the central control DCS operator exits the fuel oil control cascade mode by performing HMI operation; After confirmation, the second on-site operator opened the crude oil pipeline reflux manual valve, and the third on-site operator quickly observed the atomization angle of the oil nozzle in the reactor through the reactor sight glass hole; After the atomization mode observation status is ended, the on-site operator restores the second return manual valve to the closed state, and the central control DCS operator restores the fuel oil control cascade mode.

[0021] The current method for observing the atomization pattern of the feedstock oil guns in the carbon black reactor's hard-line production line relies on human judgment. This involves observing the normal atomization pattern within the sight glass. Different operators have varying visual angles and errors, and the oil gun position is adjusted primarily based on experience, resulting in a non-standardized process. This requires the coordination of multiple personnel—two on-site personnel and one in the control center, for a total of three. Manually judging the feedstock oil gun atomization pattern lacks unified standards and records for comparison. On-site operators rely entirely on experience, which is short-sighted and hasty.

[0022] Supcon DCS is the abbreviation for Distributed Control System (DCS), which can be directly translated as "distributed control system" or "distributed computer control system." A distributed control system is a new generation of instrumentation and control systems based on microprocessors, employing the design principles of decentralized control functions, centralized display and operation, and a balance of decentralized autonomy and integrated coordination. Distributed control systems are abbreviated as DCS, which can also be directly translated as "distributed control system" or "distributed computer control system."

[0023] Distributed control systems (DCSs) employ the fundamental design principle of decentralized control and centralized operation and management, employing a multi-layered, hierarchical, and cooperatively autonomous structure. Their key characteristics are centralized management and decentralized control. DCSs have found widespread application in various industries, including power generation, metallurgy, and petrochemicals.

[0024] This embodiment provides a remote monitoring automatic control device for the atomization mode of a raw material oil gun of a reactor. The automatic operation of the device is controlled by a distributed control system (DCS).

[0025] like Figure 1 As shown, the oil pipeline of this device is first designed. One end of the fuel oil gun 105 is inserted into the reactor 101 from one side, and the outlet end faces the atomization image area 104 in the reactor 101. The inlet end of the fuel oil gun 105 is connected to the oil inlet pipe 108. The fuel oil gun 105 is provided with sight glass holes 102 on both sides. A monitoring mechanism 103 is set at the end of any sight glass hole 102. The monitoring mechanism 103 has the function of video image acquisition and image data storage. Figure 1The monitoring mechanism 103 is set at the sight glass hole 102 above the fuel oil gun 105. The monitoring mechanism 103 includes a forward slide bar 2 and a downward slide bar 3. The forward slide bar 2 is mounted in front of the sight glass hole 102 (the forward slide bar 2 can be mounted on the open space in front of the sight glass hole 102 by a bracket, or one end of the forward slide bar 2 can be fixed to the side wall of the reactor 101 by a bracket. When implementing this solution, technicians can flexibly select the fixing method of the forward slide bar 2 according to the on-site equipment conditions). The downward slide bar 3 is slidably set on the forward slide bar 2, and a collection unit 4 for collecting images of the atomized image area 104 is set at the lower end of the downward slide bar 3. The shooting angle of the collection unit 4 corresponds to the atomized image area 104.

[0026] The horizontal movement stroke of the collection unit 4 is adjusted by the forward slide bar 2, and the vertical movement stroke of the collection unit 4 is adjusted by the downward slide bar 3, so that the movement position of the collection unit 4 in the X direction (horizontal direction) and the Y direction (vertical direction) can be adjusted remotely and automatically without human intervention.

[0027] A first fuel oil automatic valve 106 for controlling the on-off of the oil circuit is provided on the oil inlet pipe 108 , and a first reflux manual valve 107 is provided on a side of the oil inlet pipe 108 close to the fuel oil gun 105 .

[0028] In particular, a fuel oil return pipe 111 is provided on the oil inlet pipe 108 between the first fuel oil automatic valve 106 and the first return manual valve 107 .

[0029] The fuel oil return pipe 111 in this embodiment includes a first pipe 112 , a second pipe 113 and a third pipe 115 .

[0030] One end of first conduit 112 is connected to oil inlet pipe 108, and the other end is connected to second conduit 113. Second conduit 113 and oil inlet pipe 108 are connected via third conduit 115. A second automatic fuel oil valve 110 and a third automatic fuel oil valve 114 are serially mounted on first conduit 112, and a second manual return valve 109 is mounted on third conduit 115.

[0031] like Figure 2As shown, the structure of the monitoring mechanism 103 including the forward slide 2 and the descending slide 3 is described. The forward slide 2 includes a first stepper motor 201, a first screw slide 202, and a first fixed plate 203. The first stepper motor 201 is fixedly mounted on one end of the first fixed plate 203. The output end of the first stepper motor 201 is fixedly connected to a first threaded rod 204, which is threadedly connected to the first screw slide 202. The two sides of the first screw slide 202 are slidably clamped on the two sides of the first fixed plate 203. The descending slide 3 is fixedly mounted on the first screw slide 202. The first stepper motor 201 rotates, causing the first threaded rod 204 to rotate, thereby causing the first screw slide 202 to rotate along the first threaded rod 204, but the first fixed plate 203 limits the rotation of the first fixed plate 203. Therefore, when the first threaded rod 204 rotates, the first screw slide 202 moves back and forth along the first threaded rod 204, thereby driving the descending slide 3 to move forward horizontally by 800-1000mm.

[0032] The descending slide 3 includes a second stepper motor 301, a second screw slide 302, and a second fixed plate 303. The second stepper motor 301 is fixedly mounted at one end of the second fixed plate 303. The output end of the second stepper motor 301 is fixedly connected to a second threaded rod 304, which is threadedly connected to the second screw slide 302. The two sides of the second screw slide 302 are slidably engaged with the second fixed plate 303. The second screw slide 302 is mounted on the second screw slide 302 (the acquisition unit 4 can be a high-definition camera). As the second threaded rod 304 rotates, the second screw slide 302 slides along the second fixed plate 303, thereby driving the acquisition unit 4 down 800-1000 mm to a shooting position in front of the viewing aperture 102.

[0033] The combined use control of the forward slide bar 2 and the descending slide bar 3 of the monitoring mechanism 103 effectively controls the start and stop of the first stepper motor 201 and the second stepper motor 301, and the forward, descending and retreat functions through the on-site PLC and the in-position proximity switch.

[0034] This arrangement effectively isolates the high-temperature area of ​​reactor 101, ensuring the lifespan of acquisition unit 4 and ensuring sufficient maintenance space and pipeline clearance within reactor 101. The stepper motor and its associated travel-position switch achieve precise positioning, enabling efficient and accurate reciprocating motion of acquisition unit 4 and rapid, precise capture with minimal error and high stability.

[0035] The acquisition unit 4 can be ensured to be fixed at the position of the viewing hole 102 each time, and the focal length of each shooting is ensured to be unchanged, so that the images acquired by the acquisition unit 4 are uniform and standardized.

[0036] This embodiment further proposes an operation method of a remote monitoring automatic control device based on the atomization mode of the raw material oil gun of the reactor, referring to Figure 3 , the operation method includes the following steps: Step S1: Start the distributed control system operation and select the atomization mode or production operation mode button selection (if the atomization mode is selected during the implementation process, the execution monitoring mechanism 103 is started and the following steps are implemented; if the production operation mode is implemented, the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are automatically controlled to be closed).

[0037] The stroke of the monitoring mechanism 103 (ie, the time intervals for starting, stopping, and resetting the first stepper motor 201 and the second stepper motor 301 ) and the focal length of the acquisition unit 4 are pre-adjusted, and the first reflux manual valve 107 is opened.

[0038] The atomization mode referred to in this step is that the execution monitoring mechanism 103 is remotely started to collect images of the atomization image area 104; the production operation mode referred to is that the second fuel oil automatic valve 110, the third fuel oil automatic valve 114 and the second reflux manual valve 109 are closed, and the first fuel oil automatic valve 106 and the first reflux manual valve 107 are opened.

[0039] Step S2: Receive remote one-button start of atomization. In atomization mode, the distributed control system receives the start-up instruction of the monitoring mechanism 103, pushes the forward slide bar 2 forward, and lowers the descending slide bar 3; the monitoring mechanism 103 adopts the automatic PLC control of the stepper motor to avoid the influence of the high temperature area of ​​the reactor and the operation of pipelines such as the on-site oil gun, and pushes it into place when it is used online, and retracts it to a safe area when it is offline.

[0040] Step S3: The distributed control system receives the signal indicating that the monitoring unit 103 has reached the designated position, opens the second reflux manual valve 109, and changes the first fuel oil automatic valve 106 from the cascade control mode (CAS mode) to the automatic mode (AUTO mode). The first fuel oil automatic valve 106 automatically opens to the designated position.

[0041] Step S4: The distributed control system accepts the automatic mode and receives the opening signal of the first fuel oil automatic valve 106. The second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are opened. The second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are connected in series using two valves to achieve the same signal control, prevent leakage in the valve, effectively prevent malfunction, and correct errors in a timely manner.

[0042] Step S5: The distributed control system receives the signal that the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are fully opened, issues a snapshot instruction to the acquisition unit 4, and saves the image acquired by the backup acquisition unit 4 through the monitoring mechanism 103; if the distributed control system receives the signal that the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are not fully opened, the distributed control system directly exits the atomization mode after counting for a certain period of time (8 seconds) and automatically returns to the production operation mode.

[0043] The monitoring mechanism 103 saves the image collected by the backup collection unit 4 and compares it with the standard image in the atomization pattern comparison graphic library to determine whether the atomization pattern of the current production oil gun is normal or not.

[0044] By fixing the start, stop, and reset intervals for the first and second stepper motors 201 and 301, the acquisition unit 4 is precisely controlled to advance and descend to a set position. The acquisition unit 4 pre-adjusts the fixed focal length and scene diameter to precisely record and capture the specific atomization scene. Standard: By setting a scene image with relatively accurate atomization as a standard and comparing it with a scene image captured during normal production operation, the correctness of the current oil gun atomization pattern can be determined. This comparison is primarily based on the oil gun's crude oil injection angle characteristics. A graphical standard is established, with the initial production adjustment for uniform angle distribution and an atomization angle of 30-40 degrees as the primary graphical scene standard.

[0045] Step S6: After the distributed control system receives the opening timer information of the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 for a certain period of time (set to 8 seconds), the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are closed. This step prevents the automatic valves from being out of position for a long time. By ignoring all steps S4 and executing the subsequent steps, the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114 are directly forced to close. Step S8 is executed, the monitoring mechanism 103 retracts, and the program executes the termination instruction.

[0046] Step S7: The distributed control system receives the closed position signal of the second fuel oil automatic valve 110 and the third fuel oil automatic valve 114, the monitoring mechanism 103 closes the collection unit 4, the forward slide bar 2 and the downward slide bar 3 automatically reset, and enters the production operation mode.

[0047] Step S8: End.

[0048] The fuel was originally refluxed through traditional manual valve control, which took approximately 60 seconds to open and close. Now, the reflux function is achieved through the opening and closing of the automatic control valve, realizing automatic and rapid control functions in approximately 5 seconds, completely replacing manual control and realizing intelligent automatic control.

[0049] It should be noted that the parts not involved in the present invention are the same as the existing technology or can be implemented by using the existing technology.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
