Description

Technical Field

[0001] This invention relates to the field of oil gun control technology, and in particular to a system for automatically cleaning the atomizing plate of an oil gun. Background Technology

[0002] During the production process of thermal power generating units, oil guns must be used for fuel injection to stabilize combustion and prevent boiler flameout during start-up, shutdown, and low-load operation. In response to the national call for resource conservation, more and more new energy units are being put into production, and the proportion of new energy power generation is increasing. Due to the instability of new energy units, traditional thermal power units are gradually shifting from their primary role in power generation to peak shaving and frequency regulation. Deep peak shaving requires the use of oil guns, and the frequent use of oil guns due to frequent peak shaving often leads to clogging of the oil gun atomizing plates.

[0003] However, in existing technologies, the main method for cleaning clogged atomizing plates in oil guns is through manual disassembly and assembly by maintenance personnel to clean the various mechanical components, which is extremely inconvenient. The existing oil gun body mainly consists of the following components: oil gun rod, oil gun propeller, oil gun advance / retreat switch, atomizing plate, swirl plate, flow divider, and clamping nut. During unit operation, when the atomizing plate is clogged, the oil gun cannot be engaged, resulting in poor atomization or no oil spray, thus preventing normal oil combustion. In this case, maintenance personnel need to clean the atomizing plate, which requires opening the oil pipeline, pulling out the entire oil gun, and then removing and cleaning the atomizing plate, swirl plate, and flow divider. After cleaning, the parts must be reassembled. Furthermore, most of the oil guns in the widely used four-corner tangential furnace type are located at a high altitude, making this work both dangerous and tedious. Therefore, how to provide an automatic system for cleaning oil gun atomizing plates is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cleaning system for the atomizing plate of an oil gun. This invention adds a retractable cleaning device inside the oil gun that matches the atomizing hole of the oil gun atomizing plate. When the unit is put into operation, the cleaning device moves in and out at regular intervals to clean the atomizing plate of the oil gun, which changes the traditional disassembly and cleaning method and improves work efficiency.

[0005] This invention improves upon existing methods for cleaning clogged oil gun atomizing plates, which primarily rely on manual disassembly and assembly by maintenance personnel to clean the various mechanical components of the oil gun—a process that is extremely inconvenient. This invention addresses this problem by adding a cleaning device. This device consists of a hollow push tube, a cleaner, and a push track embedded within the oil gun pipeline. When the pusher is activated, the solenoid valve is energized, propelling the cleaner along the push track to the oil gun atomizing plate to clean it. During this time, the atomizing plate cannot atomize. When the pusher is deactivated, the solenoid valve is energized, retracting the cleaner along the push track, restoring atomization to the oil gun atomizing plate. This timed advance and retraction cleaning device cleans the oil gun atomizing plate when the unit is in operation, solving the problem of inconvenience and improving work efficiency.

[0006] This invention improves upon existing technologies where, during the timing of oil gun engagement, the cleaning device gets stuck when cleaning the atomizing disc of the oil gun via a pre- and post-positioning cleaning mechanism. This prevents the cleaning device from retracting and causes the atomizing disc to become stuck. This invention addresses this issue through a local control loop. When the oil gun is engaged and the oil angle valve is fully open, two time-delay relays (SJ1 for 2 seconds and SJ2 for 10 minutes) are used to achieve a 10-minute retraction and 2-second advance of the thruster. This control is repeated in a loop. When the oil gun is fully retracted or the oil angle valve is closed, the thruster stops advancing. If the thruster fails to retract within 5 seconds during the cyclical advance, an alarm indicator light illuminates, and an alarm signal is sent to the DCS, interlocking to close the oil angle valve and disengaging the oil gun. The local thruster can also be switched to a remote local switch via buttons SB1 and SB2 for manual cleaning of the atomizing disc, effectively preventing the cleaning device from failing to retract and causing the atomizing disc to become stuck.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A system for automatically cleaning the atomizing plate of an oil gun includes: a cleaning device, an alarm system, and a DCS interlocking circuit;

[0009] The cleaning device includes:

[0010] Thruster;

[0011] A cleaner is embedded in the oil gun pipe, and a propulsion rail is provided inside the cleaner and the propulsion rail is provided on the inner wall of the oil gun pipe;

[0012] The propulsion tube is embedded in the oil gun pipe and is fixedly connected to the propulsion track. A groove is provided on the propulsion tube.

[0013] An atomizing plate is disposed inside the oil gun pipe, and the atomizing plate has a plurality of atomizing holes, and the cleaner matches the plurality of atomizing holes;

[0014] The propulsion tube is used to advance the cleaner along the propulsion track to the atomizing plate;

[0015] The cleaner is used to clean the sludge from the atomizing holes on the atomizing plate and spray the sludge in with the fuel.

[0016] In some embodiments of this application, the cleaning device further includes:

[0017] An inlet solenoid valve is mounted on the thruster;

[0018] A de-electromagnetic valve is disposed on the thruster;

[0019] A compressed air connector, one end of which is connected to the inlet solenoid valve and the outlet solenoid valve.

[0020] In some embodiments of this application, the cleaning device further includes:

[0021] A position control switch is provided at the end of the propulsion pipe furthest from the propeller.

[0022] A retraction switch is provided at one end of the propulsion pipe near the propeller;

[0023] The advance and retreat switches are used to monitor the advance and retreat status of the thruster in real time.

[0024] In some embodiments of this application, the thruster is used to control the thruster's forward and backward movement by controlling compressed air through the compressed air connector according to the inward solenoid valve and the outward solenoid valve.

[0025] In some embodiments of this application, it also includes:

[0026] An oil supply pipe, one end of which is located inside the oil gun pipe, and the other end of which is located outside the oil gun pipe;

[0027] A swirling vane is disposed on one side of the cleaner;

[0028] A protective tube is disposed inside the oil gun pipe at the end away from the propeller;

[0029] A flow divider is disposed inside the protective tube and close to the side of the fuel injection hole of the protective tube.

[0030] In some embodiments of this application, the alarm system includes a time-delay relay SJ1, a time-delay relay SJ2, an oil angle valve open switch K1, an oil gun in-position switch K2, a thruster in solenoid valve K3, a thruster out solenoid valve K4, a time-delay relay SJ3, an alarm indicator LR1, a DCS alarm signal sender, a remote / local switching switch K5, an in-position button SB1, an out-position button SB2, an out-position button K6, and an in-position button K7.

[0031] There are two time delay relays SJ1 and SJ2, and the two time delay relays SJ1 and SJ2 are connected in parallel. The oil angle valve open position switch K1 is connected in series with the oil gun in position switch K2. The propeller in solenoid valve K3 is connected in series with the propeller retract solenoid valve K4 and the time delay relay SJ3.

[0032] In some embodiments of this application, the delay relay SJ1 has a delay of 10 minutes, the delay relay SJ2 has a delay of 2 seconds, and the delay relay SJ3 has a delay of 5 seconds.

[0033] In some embodiments of this application, the DCS interlock circuit is used to delay the thruster by 2 seconds via the delay relay SJ1 and 10 minutes via the oil angle valve when the oil gun is in position and the oil angle valve is in position. This allows the thruster to retract for 10 minutes and advance for 2 seconds, and the above action is repeated until the oil gun is in position or the oil angle valve is closed, at which point the thruster is stopped. If the thruster does not retract after a 5-second delay when it is repeatedly advancing, the alarm indicator LR1 illuminates and the DCS alarm signal is sent to the DCS, which then interlocks and closes the oil angle valve and stops the oil gun from operating.

[0034] In some embodiments of this application, there are four propulsion tubes, and the propulsion tubes are hollow tubes.

[0035] In some embodiments of this application, there are two compressed air connectors.

[0037] (1) The present invention cleans the atomizing plate of the oil gun by using a timed advance and retreat propeller, so as to avoid the atomizing plate of the oil gun being blocked due to long-term use, resulting in the oil gun being blocked and not spraying oil or poor fuel atomization effect.

[0038] (2) An alarm system was added to the cleaning device to prevent the cleaning device from being unable to disengage the jammed oil gun atomizing plate, which would affect the atomization effect. The alarm system was also sent to the DCS for operators to monitor, which improved the stability of the device's operation.

[0039] (3) The present invention also adds an interlocking circuit so that when the cleaning device cannot be withdrawn, the oil angle valve is closed to withdraw the oil gun, thus protecting the safety of the oil gun and preventing damage to the oil gun. Attached Figure Description

[0045] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the communication between the inner sides of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In existing technologies, the main method for cleaning clogged atomizing plates in oil guns involves maintenance personnel manually disassembling and reassembling the oil gun to clean its various mechanical structures, which is extremely inconvenient. The existing oil gun body mainly consists of the following components: oil gun rod, oil gun propeller, oil gun advance / retreat switch, atomizing plate, swirl plate, flow divider, and clamping nut. During unit operation, when the atomizing plate is clogged, the oil gun cannot be engaged, resulting in poor atomization or no oil spray, thus preventing normal oil combustion. In this case, maintenance personnel need to clean the atomizing plate, which requires opening the oil pipeline, pulling out the entire oil gun, and then removing and cleaning the atomizing plate, swirl plate, and flow divider. After cleaning, the parts are reassembled. Furthermore, most of the oil guns in the currently widely used four-corner tangential furnace type are located at a high altitude, making this work both dangerous and tedious.

[0050] Therefore, the present invention provides an automatic cleaning system for the atomizing plate of an oil gun. The present invention uses a cleaning device installed inside the oil gun that can move forward and backward to match the atomization hole of the oil gun atomizing plate. When the unit is put into operation, the cleaning device moves forward and backward at regular intervals to clean the oil gun atomizing plate. To prevent the cleaning device from getting stuck, an alarm system is added to monitor the forward and backward movement of the cleaning device and issue an alarm. The alarm signal is sent to the DCS for operators to monitor. In addition, the oil gun is also interlocked to withdraw and the oil angle valve is closed to prevent the cleaning device from being unable to withdraw and getting stuck on the oil gun atomizing plate.

[0051] The interlocking of DCS belongs to the switch interlocking or equipment start-stop interlocking that is frequently used in the production process. It has the following advantages: (1) DCS is used for continuous process measurement, routine control (continuous, sequential, intermittent, etc.), operation control management, and ensures stable operation of the equipment; (2) DCS is a "dynamic" system. It continuously monitors, calculates and controls process variables and dynamically controls the operation process to ensure the accuracy of monitoring results; (3) DCS can automatically display faults. DCS is not strict about the length and requirements of maintenance time. DCS can switch between automatic and manual operation; (4) DCS system only performs general interlocking, motor start-stop, sequence control, etc. The safety level requirements are not as high as SIS; (5) DCS system is generally composed of human-machine interface operation station, communication bus and field control station. DCS does not contain detection and execution part; (6) In order to realize the automation of the control process, the operator can change some output actions of DCS system.

[0052] See Figure 1-3 As shown, the disclosed embodiments of the present invention provide a system for automatically cleaning the atomizing plate of an oil gun, including: a cleaning device, an alarm system, and a DCS interlocking circuit;

[0053] The cleaning device includes:

[0056] The push tube 3 is embedded in the oil gun pipe and is fixedly connected to the push rail 2. A groove 28 is provided on the push tube 3.

[0057] Atomizing plate 25 is installed inside the oil gun pipe. Atomizing plate 25 has several atomizing holes, and the cleaner 1 matches the several atomizing holes.

[0058] The propulsion tube 3 is used to advance the cleaner 1 along the propulsion track 2 to the atomizing plate 25;

[0059] The cleaner 1 is used to clean the sludge in several atomizing holes on the atomizing plate 25 and spray the sludge in with the fuel.

[0060] In one specific embodiment of this application, the cleaning device further includes:

[0061] Solenoid valve 5 is installed on thruster 4;

[0062] The solenoid valve 6 is deactivated and is mounted on the thruster 4.

[0063] Compressed air connector 9, one end of which is connected to inlet solenoid valve 5 and outlet solenoid valve 6.

[0064] In one specific embodiment of this application, the cleaning device further includes:

[0065] The advance position switch 7 is located at the end of the propulsion tube 3 away from the propeller 4;

[0066] The retraction switch 8 is located at one end of the propulsion tube 3 near the propeller 4.

[0067] The forward and backward switches 7 and 8 are used to monitor the forward and backward status of the thruster 4 in real time.

[0068] In one specific embodiment of this application, the thruster 4 is used to control the thruster 4 to move forward or backward by controlling compressed air through the compressed air connector 9 according to the forward solenoid valve 5 and the backward solenoid valve 6.

[0069] In one specific embodiment of this application, it further includes:

[0070] Oil supply pipe 27, one end of oil supply pipe 27 is set inside the oil gun pipe, and the other end of oil supply pipe 27 is set outside the oil gun pipe;

[0071] Swirl vane 24 is disposed on one side of cleaner 1;

[0072] Protective tube 26 is located inside the oil gun pipe at the end furthest from the thruster 4;

[0073] Diverter plate 23 is disposed inside the protection tube 26 and is located on the side close to the oil injection hole of the protection tube 26.

[0074] In one specific embodiment of this application, see [reference] Figure 4 As shown, the alarm system includes time delay relay SJ1, time delay relay SJ2, oil angle valve open switch K1, oil gun in position switch 7K2, pusher 4 in solenoid valve 5K3, pusher 4 retract solenoid valve 6K4, time delay relay SJ3, alarm indicator LR1, DCS alarm signal sender K5, remote / local switching switch K5, in button SB1, retract button SB2, retracted position K6, and in position K7;

[0075] There are two time delay relays SJ1 and SJ2, and the two time delay relays SJ1 and SJ2 are connected in parallel. The oil angle valve open position switch K1 and the oil gun in position switch 7K2 are connected in series. The propeller 4 inlet solenoid valve 5K3, the propeller 4 outlet solenoid valve 6K4, and the time delay relay SJ3 are connected in series.

[0076] In one specific embodiment of this application, the delay relay SJ1 has a delay of 10 minutes, the delay relay SJ2 has a delay of 2 seconds, and the delay relay SJ3 has a delay of 5 seconds.

[0077] In one specific embodiment of this application, the DCS interlock circuit is used to delay the oil gun in place and the oil angle valve in place by delaying for 2 seconds through time delay relay SJ1 and delaying for 10 minutes through time delay relay SJ2, so that the pusher 4 retracts for 10 minutes and advances for 2 seconds, and repeats the above action until the oil gun retracts in place or the oil angle valve closes, at which point the pusher 4 stops. When the pusher 4 is pushed forward again, if it does not retract after a 5-second delay, the alarm indicator LR1 lights up and an alarm signal is sent to the DCS, which then interlocks and closes the oil angle valve and stops the oil gun operation.

[0078] In one specific embodiment of this application, there are four propulsion tubes 3, and the propulsion tubes 3 are hollow tubes.

[0079] In one specific embodiment of this application, there are two compressed air connectors 9.

[0080] According to the first technical concept of the present invention, the present invention embeds a hollow propulsion tube, a cleaner, and a propulsion track inside the oil gun pipeline. When the propulsion advance command is issued, the advance solenoid valve is energized, and the propulsion pushes the cleaner along the propulsion track to the oil gun atomizing plate to clean the oil gun atomizing plate. At this time, the oil gun atomizing plate cannot atomize. When the propulsion retract command is issued, the retract solenoid valve is energized, and the propulsion pushes the cleaner out along the propulsion track, and the oil gun atomizing plate resumes atomization. When the unit is put into operation, the timed advance and retract cleaning device cleans the oil gun atomizing plate, effectively solving the problem of frequent clogging of the oil gun atomizing plate and reducing the workload of maintenance personnel in cleaning the oil gun atomizing plate.

[0081] According to the second technical concept of the present invention, the present invention implements a local control circuit. When the oil gun is in position and the oil angle valve is open (i.e., the oil gun is engaged), two time-delay relays, SJ1 delaying for 2 seconds and SJ2 delaying for 10 minutes respectively, enable the propeller to retract for 10 minutes and advance for 2 seconds. The above control is repeated and cyclical. When the oil gun is in position or the oil angle valve is closed, the propeller stops advancing. When the propeller is advancing cyclically, if it does not retract within 5 seconds after the delay, the alarm indicator light illuminates and the alarm signal is sent to the DCS, which interlocks and closes the oil angle valve and stops the oil gun operation. The local propeller can also be switched to a remote local switch to manually clean the oil gun atomizing plate locally via buttons SB1 and SB2, effectively preventing the cleaning device from failing to retract and causing jamming of the oil gun atomizing plate.

[0082] In summary, this invention adds a retractable cleaning device inside the oil gun that matches the atomization hole of the oil gun's atomizing plate. When the unit engages the oil gun, the cleaning device is moved forward and backward at regular intervals to clean the oil gun's atomizing plate. Furthermore, to prevent the cleaning device from jamming, an alarm system is added to monitor the retraction status of the cleaning device in real time and issue an alarm. The alarm signal is sent to the DCS for operators to monitor. In addition, the oil gun is withdrawn by an interlock and the oil angle valve is closed to prevent the cleaning device from being unable to withdraw and jamming the oil gun's atomizing plate.
