[0002] With the continuous development of society and the progress of science and technology, the use of flares is becoming more and more widespread, and the related technologies of flares are also constantly improving. At present, flares are also used in oilfields with high sulfur content in associated gas.

[0003] Since most of the torches currently in use are fixed torches that cannot be moved or disassembled, they cannot be disassembled for reuse, which easily leads to a large waste of resources and is not conducive to the use of torches. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: since most torches currently in use are fixed torches that cannot be moved or disassembled, they cannot be disassembled for reuse, which easily leads to a waste of a lot of resources and is not conducive to the use of torches. Therefore, this invention proposes a mobile modular torch remote automatic ignition device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile modular torch remote automatic ignition device includes a chassis, a torch head, two torch cylinders, and a torch base. The torch base is located above the chassis. The torch head, the two torch cylinders, and the torch base each include three support tubes, which are connected by a tripod. A control box is installed on the chassis.

[0007] Each of the support tubes is fixedly connected to a flange, and a positioning groove is provided on the support tube. A positioning rod is fixedly connected to one end of each support tube. The positioning rod and the positioning groove are slidably connected. The two flanges are connected by multiple threaded rods. The cross-section of each threaded rod is set to T-shaped, and a nut is threadedly connected to the threaded rod.

[0008] Annular blocks are slidably arranged on the outer side of multiple support tubes. The cross-section of the annular blocks is circular. Each annular block is provided with a limit component. The limit component includes multiple rubber blocks fixedly installed on the annular block. The multiple rubber blocks are equidistantly arranged. A rotating shaft is rotatably installed on the torch head. An installation block is fixedly connected to the upper end of the rotating shaft. A screen cover is provided on the installation block.

[0009] Each of the annular blocks has two symmetrically arranged fixing rods fixedly connected to its upper end face. Each fixing rod has a locking block slidably connected to its upper end. The bottom surface of the locking block has a limiting groove. The upper end of the fixing rod is slidably connected to the limiting groove. The locking block is engaged with the corresponding support tube.

[0010] Preferably, a sealing gasket is provided on the outer side of each threaded rod, the sealing gasket having a circular cross-section, and each sealing gasket is installed between the corresponding flange and the nut.

[0011] Preferably, a sealing ring is fixedly connected to each of the positioning grooves, and the sealing ring is configured as an annular ring.

[0012] Preferably, the mounting block has an opening, the screen cover is fixedly connected to a fixing block, and the fixing block is fixedly connected to two symmetrically arranged rectangular blocks. The mounting block is connected to the rectangular blocks by two screws.

[0013] Preferably, a servo motor is installed on the torch head, and the drive end of the servo motor is fixedly connected to the rotating shaft.

[0014] Preferably, two oil tanks are installed on the chassis, and both oil tanks are located on one side of the support pipe.

[0015] A portable modular torch remote automatic ignition device, the installation method of which includes the following steps:

[0016] S1: Install the flare base on the chassis, then lift one of the flare cylinders vertically with a crane and move it horizontally above the flare base, so that the two flanges are exactly opposite each other, and the positioning rod and positioning groove are connected.

[0017] S2: Connect the flanges in pairs with multiple threaded rods, then pass the gasket through the lower end of the threaded rods, and then rotate the nut until the end face of the nut and the surface of the gasket are in contact.

[0018] S3: Pull the fixing rod upwards, the rubber block deforms and fits against the corresponding nut surface, push the locking block until one end of the locking block engages with the corresponding slot on the support tube;

[0019] S4: Anchor the torch fixing rope to the ground and lock it in place;

[0020] S5: Connect the ignition device signal transmission cable and power control line, connect the various instrument signal lines on the main torch to the control box, and perform pressure test ignition.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The torch head, two torch cylinders, and torch base are connected by flanges, which allows the torch to be moved and disassembled for reuse. Any torch structures with the same manufacturing process can be combined and used in any way, avoiding a large waste of resources and facilitating the use of the torch.

[0023] The flare burner uses a fluid seal as the system's backfire prevention device, and flame arresters are installed in the pipeline. The device operates as an unattended device and can realize manual / automatic ignition on site. Two sets of high-pressure igniters are used to ensure reliable ignition when the system is vented.

[0024] Conventional torches use gas for their continuous flame accompaniment, but this device incorporates a diesel accompaniment system. When a gas source cannot be provided on-site, the system can be switched to diesel accompaniment mode. In diesel accompaniment mode, fuel consumption must be controlled at 20L / h, and at this rate, diesel fuel must be delivered via a custom-designed pump to a nozzle 16 meters high to achieve diesel atomization.

[0025] The flame can be kept burning even when the wind force is level 7. An automatic wind shield is designed on the torch head, which can automatically rotate to prevent wind according to the wind force detection direction.

[0026] This type of flare has both diesel-fired and natural gas-fired modes. Both can be used separately or simultaneously. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Reference Figure 1-6 A mobile, modular, remote automatic ignition device for a flare system includes a chassis 1, a flare head 23, two flare tubes, and a flare base. The flare head 23 is 1 meter high, the upper flare tube is 5 meters high, the lower flare tube is 6 meters high, and the flare base is 4 meters high. It also includes four pipelines: a venting gas combustion pipeline (DN65), a venting gas pipeline (DN65), a pilot flame pipeline (diesel-fueled, DN6), and a backup pilot flame pipeline (natural gas-fueled, DN20). The flare burner is located at the very top, with specifications of DN65*1000*425. The total flare height is 16 meters. The entire system is fixed using a self-supporting structure. The venting flame height is 2-5 meters; the pilot flame height is 300-400 mm (adjustable to 1-1.5 meters). This device can be used in dry, windy, and sandy environments with high wind speeds.

[0036] The torch base is located above the chassis 1. The torch head 23, the two torch cylinders, and the torch base each include three support pipes 4 of different lengths. The three support pipes 4 are connected by tripods 6. The number of tripods 6 connected to each set of three support pipes 4 can be different. A control box 3 is installed on the chassis 1. A flange 5 is fixedly connected to each support pipe 4. A positioning groove is opened on the support pipe 4. A positioning rod 14 is fixedly connected to one end of each support pipe 4. A positioning groove can be opened at one end of each support pipe 4, or a positioning rod 14 can be installed. Alternatively, positioning grooves can be opened at both ends and positioning rods 14 can be installed. The positioning rods 14 and the positioning grooves are slidably connected. The two flanges 5 are connected by multiple threaded rods 19. The cross-section of each threaded rod 19 is T-shaped. A nut 16 is threadedly connected to the threaded rod 19.

[0037] Annular blocks 11 are slidably arranged on the outer side of multiple support tubes 4. The cross-section of the annular blocks 11 is circular. Each annular block 11 is provided with a limiting component, which includes multiple rubber blocks 12 fixedly installed on the annular block 11. The multiple rubber blocks 12 are equidistantly arranged. A sealing gasket 17 is provided on the outer side of each threaded rod 19. The cross-section of the sealing gasket 17 is circular. Each sealing gasket 17 is installed between the corresponding flange 5 and nut 16. The sealing gasket 17 is passed through the lower end of the threaded rod 19, and the sealing gasket 17 is in contact with the surface of the lower flange 5. Then the nut 16 is rotated until the end face of the nut 16 is in contact with the surface of the sealing gasket 17. The sealing gasket 17 facilitates the installation of the nut 16.

[0038] Each positioning groove is fixedly connected with a sealing ring 15, which is circular. The positioning rod 14 and the positioning groove of the support tube 4 are slidably connected. The surfaces of the sealing ring 15 and the positioning rod 14 are in close contact, which can improve the connection tightness between the positioning rod 14 and the positioning groove. Two symmetrically arranged fixing rods 18 are fixedly connected to the upper end face of each annular block 11. The upper end of each fixing rod 18 is slidably connected with a locking block 13. The bottom surface of the locking block 13 is provided with a limit groove. The upper end of the fixing rod 18 and the limit groove are connected. The sliding connection allows the locking block 13 to engage with the corresponding support tube 4. When the fixing rod 18 is pulled upward, the annular block 11 moves vertically upward at the same time. As each rubber block 12 moves upward, it will come into contact with the surface of the corresponding nut 16. The rubber block 12 deforms and pushes the locking block 13. The locking block 13 and the fixing rod 18 slide relative to each other until one end of the locking block 13 engages with the corresponding slot on the support tube 4. The friction between the rubber block 12 and the nut 16 is relatively large, which can prevent the nut 16 from loosening to a certain extent.

[0039] A rotating shaft 10 is rotatably mounted on the torch head 23. A mounting block 9 is fixedly connected to the upper end of the rotating shaft 10. A screen cover 7 is provided on the mounting block 9. An opening 22 is opened on the mounting block 9. A fixing block 8 is fixedly connected to the screen cover 7. Two rectangular blocks 21 arranged symmetrically are fixedly connected to the fixing block 8. The mounting block 9 is connected to the rectangular blocks 21 by two screws 20, which connects the fixing block 8 and the opening 22. Then, the rectangular blocks 21 and the mounting block 9 are connected together by screws 20. The screen cover 7 can be installed on the rotating shaft 10. Similarly, when the screen cover 7 is damaged, it can also be replaced.

[0040] A servo motor is installed on the torch head 23. The drive end of the servo motor is fixedly connected to the rotating shaft 10. Under the drive of the servo motor, the rotating shaft 10 can be rotated, and the screen cover 7 will rotate at the same time, so as to control the position of the screen cover 7. Two oil tanks 2 are installed on the chassis 1, and both oil tanks 2 are located on one side of the support tube 4.

[0041] A portable modular torch remote automatic ignition device, the installation method of which includes the following steps:

[0042] S1: Install the flare base on the chassis 1, then lift one of the flare cylinders vertically with a crane and move it horizontally above the flare base, so that the two flanges 5 are exactly opposite each other, and the positioning rod 14 and the positioning groove are connected.

[0043] S2: Connect two flanges 5 together with multiple threaded rods 19, then pass the sealing gasket 17 through the lower end of the threaded rod 19, and then rotate the nut 16 until the end face of the nut 16 and the surface of the sealing gasket 17 are in contact.

[0044] S3: Pull the fixing rod 18 upward, the rubber block 12 deforms and fits against the surface of the corresponding nut 16, push the locking block 13 until one end of the locking block 13 engages with the corresponding slot on the support tube 4.

[0045] S4: Anchor the torch fixing rope to the ground and lock it in place;

[0046] S5: Connect the ignition device signal transmission cable and power control line, connect the various instrument signal lines on the main torch to control box 3, and perform pressure test ignition.

[0047] The process requirements for this equipment are as follows:

[0048] (1) The torch uses flange 5 connection for easy installation and disassembly, so as to facilitate the relocation of the equipment with the client. The medium contains corrosive gas H2S and corrosive alkaline solution. Considering the corrosion resistance of the torch body material, the main torch material is all 316L. The torch is equipped with matching ignition device and atomizing gun for easy operation and control. The torch must have strong resistance to harsh weather conditions, and must be resistant to strong winds, heavy rains, and lightning to avoid environmental factors causing unsuccessful ignition or extinguishing due to environmental factors.

[0049] (2) The diesel fuel combustion process is as follows: A 100L fuel tank is installed at the bottom of the torch. When the main torch needs to be ignited, the fuel pump is automatically turned on. The fuel pump delivers diesel fuel to the diesel atomizing gun at the torch head. The fuel atomizing gun is ignited electronically to keep the fuel atomizing gun burning. When the released gas reaches the set safe release pressure, the main torch valve is automatically opened. The released gas comes into contact with the open flame and is ignited. When the pressure reaches the set low pressure, the release valve is automatically closed and the torch waits for the next ignition command. The outlet of the long-burning atomizing gun is designed to be highly efficient and energy-saving. The combustion is stable and does not detach. 100L of diesel fuel can burn continuously for 25 hours without going out.

[0050] (3) When the torch detaches during combustion, the height of the pilot flame should be 300-400mm. The flame height can be adjusted to 500-800mm according to the on-site production conditions. When the pilot flame is the flame of the atomizing oil gun, the flame height of the atomizing oil gun should be about 1.5 meters and should not detach. It must also ensure that the flame does not go out when the combustible medium in the main venting gas decreases.

[0051] (4) Flame monitoring: The torch is equipped with one set of ultraviolet flame monitor and two thermocouples to monitor the flame and ensure the safety of the release;

[0052] (5) Monitoring of oil tank 2: The oil tank 2 has a built-in level gauge. When the oil level is lower than the set height value, the oil pump stops working and alarms are triggered, accompanied by an alarm light and sound.

[0053] (6) The manual / automatic control cabinet is installed on site, and the control room is equipped with an alarm light to alarm in case of accidental fire failure and notify the operator. Ignition is automatic, and manual ignition can also be done by remote control. The remote control distance is 300-500 meters with no obstruction.

[0054] (7) The main body of the torch is detachable to facilitate loading and transportation. After ground docking installation, it is hoisted as a whole. The torch is fixed to the cement base with bolts in an upright manner. The bottom is fixed with tie rods from the four corners of the cement base (1.5 meters high). The middle and top are fixed with 3 tension ropes (6 in total). The cement base has the following dimensions: length, width and height: 3m*2.8m*0.8m.

[0055] (8) The flare equipment can operate safely and reliably under extreme conditions, and the design life of the flare is not less than 15 years;

[0056] (9) The structure of the flare system should be as simple as possible while ensuring reliability and rationality, so as to reduce project investment and facilitate installation;

[0057] (10) The diameter of the flare head 23 meets the emission requirements, the incineration rate is not less than 99%, and the flare head 23 and the flare tube are connected by a flange 5 for easy disassembly;

[0058] (11) The ignition control cabinet can realize local manual / automatic switching of ignition / remote control ignition;

[0059] (12) Cables within the flare zone are laid in galvanized pipes, while cables at the boundary are buried underground. The cable protection pipes are fixed on the flare tube support and laid from top to bottom to the local control box 3.

[0060] (13) The entire set of equipment is integrated and skid-mounted, which is convenient to disassemble and assemble, easy to maintain and reliable;

[0061] (14) A drain valve is installed at the bottom of the flare tube;

[0062] (15) All electrical equipment must be explosion-proof, the explosion-proof area is Class I Zone 2, the explosion-proof level is not lower than ExdⅡBT4, and the protection level of instruments and control panels is IP65;

[0063] (16) The flange 5 standard adopts HG / T20592-20635-2009, RF face with neck flange, and the interface is provided by the supplier with matching flange 5, threaded rod 19, nut 16 and sealing gasket 17;

[0064] (17) The ignition cable is a special cable, provided by the supplier;

[0065] (18) The product is subjected to external anti-corrosion treatment before leaving the factory.

[0066] The device is also equipped with a torch remote control system, which includes ultraviolet monitoring sensors, two thermocouples for flame monitoring, and other devices. The system is connected to a computer system.

[0067] (1) When the wind is strong at the scene, it is very likely to cause the flame of the lamp to go out. In order to avoid this situation, a screen cover 7 is installed on the torch head 23. When the system detects that the wind force is strong enough to blow out the flame of the lamp, the servo motor is started. When the servo motor rotates, it drives the screen cover 7 to rotate through the rotating shaft 10 to shield the direction of the wind force, so as to protect the flame of the lamp from being blown out by the wind.

[0068] (2) When the flame is accidentally extinguished, the ultraviolet monitoring sensor detects the flame extinguishing and wirelessly transmits the flame extinguishing signal to the remote computer system hub.

[0069] (3) The system central system collects the signal from the flame monitoring sensor and starts to self-check the torch working process system. If the system is abnormal, it issues a warning (the diesel fuel is lower than the preset minimum height of the fuel tank 2, the fuel pump cannot work properly, the ignition device cannot ignite properly, etc.).

[0070] (4) If the system self-test is normal, the high-energy igniter will automatically start to perform the ignition action.

[0071] This equipment is used in high sulfur environments (H2S≤300000ppm), and safe and complete combustion must be ensured.

[0072] In this invention, during use, the flare base is first installed on the chassis 1. Then, one of the flare tubes is vertically lifted by a crane and horizontally moved above the flare base, so that the positioning rods 14 of each support tube 4 on the flare tube are slidably connected to the positioning grooves of the three support tubes 4 on the flare base. The sealing ring 15 and the surface of the positioning rod 14 are tightly attached. Then, multiple threaded rods 19 are used to connect the flanges 5 in pairs. One end of each threaded rod 19 passes through the through hole on the two flanges 5 until the T-shaped threaded rod 19 is in contact with the surface of the upper flange 5. Then, the sealing gasket 17 is passed through the lower end of the threaded rod 19 and is in contact with the surface of the lower flange 5. Then, the nut 16 is rotated, and the nut 16 is threadedly connected to the threaded rod 19 until the end face of the nut 16 is in contact with the surface of the sealing gasket 17.

[0073] Then, pull the fixing rod 18 upward, and the annular block 11 moves vertically upward at the same time. During the upward movement of each rubber block 12, it will come into contact with the surface of the corresponding nut 16, and the rubber block 12 will deform. At this time, the fixing rod 18 moves to a certain position, and then push the locking block 13. The locking block 13 and the fixing rod 18 slide relative to each other until one end of the locking block 13 engages with the corresponding slot on the support tube 4. The friction between the rubber block 12 and the nut 16 is relatively large, which can prevent the nut 16 from loosening to a certain extent. This is conducive to the stable connection of the two flanges 5 and to improving the firmness of the connection between the torch base and the torch tube. Similarly, another torch tube is installed on top of this torch tube. Finally, the torch head 23 is connected to the torch tube above it, so that the torch can be moved and can be disassembled for reuse. Any torch structure with the same manufacturing process can be combined and used in any way, avoiding a large waste of resources and facilitating the use of the torch.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
