Description

Technical Field

[0001] The utility model relates to the technical field of torch combustion safety protection, in particular to a torch smoldering prevention protection system. Background Art

[0002] At present, torches are widely used, and there are many types of torches. The safety of the torch operation process cannot be ignored. For example, when an industrial overhead torch is in operation, its emission range varies greatly. When the displacement is reduced, due to the low flow rate of the exhaust gas in the main barrel of the torch, the external air is easy to enter the barrel cavity from the top outlet of the main barrel of the torch along the inner wall of the barrel, and mix with the exhaust gas in the barrel cavity to form a combustible mixture. At the same time, the combustible mixture is easily ignited by the flame outside the torch outlet to form a flame zone in the main barrel of the torch, forming smoldering. Because the heat of the flame cannot be quickly discharged and is absorbed by the torch head structure, it is very easy to deform and damage the torch head structure, posing a threat to personnel, production, and property safety. In the prior art, in order to improve the smoldering situation, an inert gas discharge plate is installed in the main barrel of the torch. The inert gas discharge plate is similar to a cover with mesh holes and is located in the barrel. When smoldering occurs, the discharge plate is opened and the inert gas is sprayed out to prevent combustion. When the flare is operating normally, the discharge plate is located in the barrel, occupying part of the barrel cavity area, affecting the air flow in the main barrel of the flare, thereby affecting the discharge and combustion of the exhaust gas.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the prior art, in order to improve the adverse effects of smoldering on the flare combustion system, some designs are to set a discharge plate for introducing inert gas near the top of the flare barrel. The discharge plate is set perpendicular to the barrel cavity and conveys inert gas downward to extinguish the fire. When the flare is operating normally, the exhaust gas needs to flow upward. The design of the discharge plate affects the normal flow of the exhaust gas and is not conducive to the discharge of the exhaust gas.

[0031] In view of this, the designer provides a flare smoldering prevention protection system, which can not only improve the smoldering situation, but also does not affect the discharge of exhaust gas when the flare system operates normally.

[0032] Please combine Figure 1-Figure 3 In this embodiment, the flare smoldering prevention protection system includes a flare main barrel 100, a temperature monitoring module 200 and an extinguishing device 300; the interior of the flare main barrel 100 is provided with a plurality of anti-flashback areas 101 arranged at intervals in the length direction of the flare main barrel 100, and the temperature monitoring module 200 is installed on the flare main barrel 100, and is used to monitor the temperature of the anti-flashback area 101 closest to the top of the flare main barrel 100 among the plurality of anti-flashback areas 101; the extinguishing device 300 is installed on the flare main barrel 100, and the extinguishing device 300 has a first state and a second state that can be switched to each other. When in the first state, the extinguishing device 300 extends into the barrel cavity of the flare main barrel 100; when in the second state, the extinguishing device 300 withdraws from the barrel cavity of the flare main barrel 100; the extinguishing device 300 is used to deliver inert gas into the barrel cavity of the flare main barrel 100.

[0033] Based on the above, the working principle of the flare smoldering prevention protection system provided in this embodiment is as follows:

[0034] It should be understood that in the initial stage of operation, the temperature monitoring module 200 can obtain the temperature information in the flare main barrel 100 in real time, and the extinguishing device 300 is in the second state, that is, it is not in a position extending into the barrel cavity of the flare main barrel 100, will not occupy the space of the barrel cavity, and will not affect the normal flow of the exhaust gas. During operation, the temperature information at the corresponding position in the flare main barrel 100 is obtained in real time through the temperature monitoring module 200. When the temperature information changes rapidly or the temperature information is greater than the threshold, it indicates that there is a smoldering phenomenon in the flare main barrel 100. Start the extinguishing device 300 and switch it from the second state to the first state. At this time, the extinguishing device 300 extends into the barrel cavity, and the extinguishing device 300 inputs the inert gas into the barrel cavity of the flare main barrel 100. The flame retardant properties of the inert gas can extinguish the flame burning in the flare main barrel 100, thereby achieving the purpose of actively improving the smoldering phenomenon, greatly reducing the negative impact of smoldering, and improving the safety and reliability of the flare system operation. When the smoldering phenomenon is eliminated, the extinguishing device 300 switches back from the first state to the second state, and the extinguishing device 300 will not affect the normal flow of the exhaust gas.

[0035] It should be noted that the extinguishing device 300 can be activated by remote control. For example, the temperature monitoring module 200 can be connected to the ground control room for communication. The real-time temperature obtained by the temperature monitoring module 200 can be directly reflected in the ground control room, and an alarm module can be set in the ground control room. When the temperature is abnormal, the alarm module is activated and an audible and visual alarm is issued to remind the operating personnel to take corresponding measures.

[0036] It should be understood that the control program for controlling the extinguishing device 300 can also be integrated into a smart terminal such as a mobile phone. When the extinguishing device 300 needs to be controlled, it is more convenient to operate through a smart terminal such as a mobile phone. In addition, a keypad can also be provided in the control room. When remote control cannot be carried out smoothly, control can be performed through the buttons on the keypad.

[0037] The following examples illustrate the details of the flare prevention protection system provided in the present application.

[0038] In this embodiment, optionally, a plurality of anti-flashback plates 110 are installed in the flare main barrel 100, and the plurality of anti-flashback plates 110 are arranged at intervals in the axial direction of the flare main barrel 100, and an anti-flashback area 101 is formed between adjacent anti-flashback plates 110. By providing a plurality of anti-flashback plates 110, the probability of smoldering can be reduced, and the stability and reliability of operation can be improved.

[0039] For example, in this embodiment, the number of the anti-backfire plates 110 may be two or three, etc. The structure and working principle of the anti-backfire plates 110 may refer to the existing known technology, and will not be described in detail in this embodiment.

[0040] In this embodiment, optionally, the extinguishing device 300 includes a plurality of gas delivery units 310, and the plurality of gas delivery units 310 are all installed on the flare main barrel 100 and are arranged at intervals in the circumferential direction of the flare main barrel 100, and each gas delivery unit 310 has a first state and a second state that can be switched with each other, and each gas delivery unit 310 is used to deliver inert gas into the barrel cavity of the flare main barrel 100.

[0041] It should be understood that the structure of each gas delivery unit 310 can be set to be the same, which is convenient for processing and manufacturing, easy for assembly, and reduces costs. In this embodiment, in order to avoid repeated description, only one gas delivery unit 310 is used as an example for description.

[0042] Please combine Figure 1In this embodiment, optionally, the gas transmission unit 310 includes an installation outer cylinder 311, a gas transmission inner cylinder 312 and a control valve 313. An assembly hole is provided on the flare main cylinder 100, and the installation outer cylinder 311 is fixed to the outside of the flare main cylinder 100 and connected to the assembly hole. The installation outer cylinder 311 can be welded to the outside of the flare main cylinder 100 to improve the sealing of the connection, and the combination strength is high, and it is not easy to be damaged during use. The gas transmission inner cylinder 312 and the installation outer cylinder 311 can be slidably matched, and the gas transmission inner cylinder 312 can extend into or exit the barrel cavity of the flare main cylinder 100 through the assembly hole; the gas transmission inner cylinder 312 is used to transport inert gas, and the control valve 313 is connected to the gas transmission inner cylinder 312 to open or close the gas transmission inner cylinder 312. The control valve 313 can be an electric valve, which can realize remote control and convenient and flexible regulation. It should be understood that the control valve 313 can also adjust the flow.

[0043] Based on the above scheme, the outer cylinder 311 is installed to achieve guidance and positioning, and the gas transmission inner cylinder 312 is used to transport the inert gas. The connection position between the outer cylinder 311 and the flare main cylinder 100 is not easy to leak, and the operation is safe and reliable. After installation, the axis of the gas transmission inner cylinder 312 is collinear with the axis of the outer cylinder 311.

[0044] Furthermore, a sealing sleeve 316 is provided between the gas transmission inner cylinder 312 and the installation outer cylinder 311, and the end of the gas transmission inner cylinder 312 away from the assembly hole extends out of the installation outer cylinder 311, and the end of the gas transmission inner cylinder 312 extending out of the installation outer cylinder 311 is used to connect with the gas source. The connection between the installation outer cylinder 311 and the flare main cylinder 100 has high sealing performance, and the sealing sleeve 316 is provided between the gas transmission inner cylinder 312 and the installation outer cylinder 311. The exhaust gas entering the space between the gas transmission inner cylinder 312 and the installation outer cylinder 311 from the assembly hole is blocked by the sealing sleeve 316 and is not easy to leak.

[0045] Please combine Figure 3 In this embodiment, optionally, an air distribution plate 314 is provided at the end of the gas delivery inner tube 312, and a plurality of air distribution holes 315 arranged at intervals are provided on the air distribution plate 314. When the gas delivery inner tube 312 is extended into the flare main tube 100 to transport the inert gas, the inert gas is discharged from the air distribution holes 315 on the air distribution plate 314, and the inert gas can be evenly distributed in the flare main tube 100, with a large coverage area, which is conducive to fire extinguishing.

[0046] It should be understood that the air balancing holes 315 on the air balancing plate 314 may be circular holes.

[0047] Please combine Figure 1 and Figure 2 In this embodiment, optionally, the angle between the axis of each gas transmission inner tube 312 and the axis of the flare main tube 100 is an acute angle or an obtuse angle. The arrangement of the multiple gas transmission inner tubes 312 is consistent, and they are radially distributed around the flare main tube 100.

[0048] For example, in this embodiment, the number of gas delivery units 310 is four, and a gas delivery inner cylinder 312 of each gas delivery unit 310 is independently controlled. When each gas delivery inner cylinder 312 is in operation, the inert gas enters the flare main barrel 100 at a certain flow rate. The inert gas can move along the inner wall of the flare main barrel 100 and in the circumferential direction of the flare main barrel 100 to form a vortex, which has a good fire extinguishing effect.

[0049] Furthermore, the axis of the gas delivery inner barrel 312 has an acute angle with the horizontal plane, so that the port of the gas delivery inner barrel 312 close to the assembly hole is closer to the top of the flare main barrel 100 than the port of the gas delivery inner barrel 312 far from the assembly hole. In this way, when the inert gas enters the flare main barrel 100 from the gas delivery inner barrel 312, the inert gas not only flows in a swirl along the circumference of the flare main barrel 100, but also flows toward the top of the flare main barrel 100, preventing external air from entering the flare main barrel 100, which is beneficial to fire extinguishing, and can move toward the top of the flare main barrel 100 with the exhaust gas, which is beneficial to the exhaust gas being ignited at the top.

[0050] Optionally, the gas delivery inner cylinder 312 can be driven by a telescope 317. For example, the telescope 317 can be a cylinder, an electric push rod, a motor screw, etc. The telescope 317 is installed on the mounting outer cylinder 311, and the telescopic end of the telescope 317 is connected to the gas delivery inner cylinder 312. The telescope 317 can be extended and retracted along the length direction of the mounting outer cylinder 311, and can drive the gas delivery inner cylinder 312 to slide back and forth relative to the mounting outer cylinder 311, thereby adjusting the position of the gas delivery inner cylinder 312, so that the air balancing plate 314 of the gas delivery inner cylinder 312 can extend from the assembly hole into the torch main cylinder 100, or the air balancing plate 314 can withdraw from the torch main cylinder 100.

[0051] In this embodiment, optionally, there are multiple temperature monitoring modules 200, and the multiple temperature monitoring modules 200 are all installed on the flare main barrel 100 and are arranged at intervals in the circumferential direction of the flare main barrel 100. By setting multiple temperature monitoring modules 200, the temperature monitoring area can be increased, thereby improving the accuracy. When the temperature information monitored by one of the temperature monitoring modules 200 is abnormal, the extinguishing device 300 can be started through the control terminal to perform corresponding processing.

[0052] In this embodiment, the flare smoldering prevention protection system may further include an image acquisition module, which is used to obtain images inside the flare main barrel 100. The safety and reliability are further improved by combining temperature information and image information. It should be understood that the image acquisition module may include an explosion-proof camera that can operate in a high temperature environment.

[0053] It should be noted that the temperature monitoring module, image acquisition module, control valves and retractors can all be connected to the control room for communication.

[0054] In this embodiment, the structural design of the flare smoldering prevention protection system can adjust the operating state of the extinguishing device 300 according to actual conditions, which can not only timely and effectively control the smoldering situation, but also ensure the smooth discharge of exhaust gas when the flare system functions normally, and the flare combustion system operates stably and reliably.

[0055] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
