[0022] This invention provides a mobile venting and ignition device for tank trucks carrying flammable and explosive gases, such as... Figures 1-15 As shown, the mobile venting and ignition device for flammable and explosive gas tank trucks includes: a venting and ignition mechanism, which includes: a counterweight base 10 and a combustion gun 1 mounted on the counterweight base 10 for igniting combustible gases discharged from the tank truck; an ambient temperature vaporizer 2 mounted on one side of the combustion gun 1 for rapidly vaporizing liquid; a gas-liquid separator 3 mounted on the frame of the ambient temperature vaporizer 2 for further separating incompletely vaporized liquid, the gas-liquid separator 3 being connected to the ambient temperature vaporizer 2 via a pipe; a set of cryogenic pipes 4 mounted on the connecting pipe between the ambient temperature vaporizer 2 and the gas-liquid separator 3, the set of cryogenic pipes 4 being connected to the combustion gun 1 and the tank truck interface respectively; a remote control ignition device 7 mounted on the support rod of the combustion gun 1 for remotely controlling the ignition of the combustion gun 1; and an electrostatic device 8 mounted on the ambient temperature vaporizer 2 for discharging the vehicle body and the ambient temperature vaporizer 2.

[0023] In this embodiment, first, the mobile emptying ignition device is placed in the upwind direction or crosswind direction of the accident tank truck, about 30-50 meters away from the tank in a safe area, the combustion gun 1 is stably placed through the counterweight base 10, the wind direction following mechanism starts to work, the real-time environmental wind speed and direction are monitored, and preparation is made for subsequent adjustment of the orientation of the combustion gun 1; the operator carries a set of low-temperature pipes 4 and corresponding conversion joints (first conversion joint 6, second conversion joint 12 and third conversion joint 13), quickly approaches the accident tank truck, selects the appropriate conversion joint according to the type of tank truck interface (liquid or gas), and connects the tank truck outlet and the low-temperature pipe 4, all connections are designed with quick plug-in, without the need for tools; before connecting the pipeline, the vehicle body and the air-cooled vaporizer are reliably grounded using the electrostatic equipment 8, and the electrostatic hazard is eliminated.

[0024] Then slowly open the valve of the accident tank truck, the medium (liquid or gas) in the tank is led out through the low-temperature pipe 4, if the discharged medium is liquid, it first enters the air-cooled vaporizer 2, the vaporizer uses the ambient temperature and its large-area heat sink to absorb heat, and rapidly vaporizes the liquid LPG / LNG into gas, if the discharged medium is gas, this step is mainly pressure buffering, the medium after vaporization or drainage then enters the gas-liquid separation tank 3, in this tank, due to the change of flow rate and centrifugal effect, any liquid droplets or impurities that are not completely vaporized will be separated and retained at the bottom of the tank, ensuring that only pure, completely gaseous substances flow to the end of the combustion gun 1.

[0025] The operator retreats to a safe area 50 meters away from the burning point in the upwind direction, issues an instruction through the remote ignition device 7, the high-pressure pulse igniter in the combustion gun 1 starts, the combustible gas led to the gun barrel is ignited, the wind direction following mechanism dynamically adjusts the orientation of the combustion gun according to the real-time wind direction, ensures stable flame, full combustion, avoids smoke backflow or flame deflection; when the pressure in the tank decreases to a safe range or the disposal task is completed, the tank truck valve is closed, the external nitrogen source hose is connected to the φ10mm nitrogen purging interface reserved on the conversion joint, the nitrogen valve is opened, and the inert gas flows through the low-temperature pipe 4, the air-cooled vaporizer 2, the gas-liquid separation tank 3 and another section of pipeline in turn, completely blowing out and replacing the residual combustible gas in the entire system, this process can also be monitored through the pressure gauge, ensuring complete purging and providing protection for safe disassembly, after that, the system pressure is zero, and the system can be safely disassembled, stored and removed from the scene; Through the modular emergency equipment such as the combustion gun, the air-cooled vaporizer 2 and the gas-liquid separation tank 3, the deployment speed at the accident scene is greatly improved, and through the introduction of the wind direction following mechanism, intelligent control of the burning direction is realized, the flame is stably burned, the safety and efficiency of the disposal process are significantly improved, and the problems of scattered components, time-consuming construction and high risk of close-range operation in the traditional method are fundamentally solved.

[0026] In the further preferred embodiment of the present application, pipe joints 5 are arranged at both ends of the low-temperature pipes 4, and the pipe joints 5 are used to connect the air-temperature vaporizer 2, the gas-liquid separation tank 3 and the combustion gun 1. The pipe joints 5 are provided with three different types of conversion joints, including a first conversion joint 6, a second conversion joint 12 and a third conversion joint 13, which are used to adapt to different sizes of the liquid-phase interface and the gas-phase interface of the tank truck. A pressure gauge 41 is arranged on the gas-liquid separation tank 3.

[0027] In the present embodiment, the operator arrives at the interface of the accident tank truck, first visually identifies the type and size of the interface, and then selects a conversion joint (the first, second or third conversion joint) matching the interface from the equipment. One end of the conversion joint is quickly locked with the interface of the tank truck, and the other end is connected with the pipe joint 5 at the end of the low-temperature pipe 4 through quick plug-in connection, thereby realizing seamless conversion between the non-standard tank truck interface and the standardized pipeline of the device. The other end of the low-temperature pipe 4 connected with the conversion joint is also connected with the inlet of the air-temperature vaporizer 2 through the pipe joint 5. Another low-temperature pipe 4 for connecting the combustion gun 1 is also assembled in the same way.

[0028] In the further preferred embodiment of the present application, the combustion gun 1 is provided with an anti-backfire valve 9 for preventing backfire of the flame. The combustion gun 1 is provided with a support 11 for supporting the combustion gun 1. An annular plate 14 is rotatably arranged on the counterweight base 10. A U-shaped clamping block 15 for limiting the support 11 is fixedly arranged on the top of the annular plate 14. The bottom block of the support 11 is inserted into the U-shaped clamping block 15.

[0029] In the present embodiment, after the device is positioned, the operator erects the combustion gun 1 and the support 11 thereof, inserts the bottom block of the support 11 into the U-shaped clamping block 15 on the annular plate 14, and completes the preliminary positioning and erection of the combustion gun 1. Then, the operator manually operates the reinforcing mechanism to fix the support 11, which can prevent the combustion gun 1 from toppling over in windy weather or due to ignition impact. During the entire emptying and ignition process, the combustible gas flowing out of the tank body passes through the combustion gun 1, and the anti-backfire valve 9 installed in the combustion gun 1 continuously works. The valve uses the principle of fluid mechanics or metal screen barrier to effectively prevent external flame from backfiring along the pipeline to the inside of the system, thereby fundamentally eliminating the risk of backfire explosion of the gas source.

[0030] In the further preferred embodiment of the present application, the electrostatic device 8 is composed of a grounding needle 81, an electrostatic clamp 82 and a grounding wire 83. The two ends of the grounding wire 83 are fixedly connected with the grounding needle 81 and the electrostatic clamp 82, respectively.

[0031] In the present embodiment, before connecting the tank truck pipeline, the operator first completes the static electricity elimination procedure, which starts with firmly inserting the grounding needle 81 into the moist soil or a dedicated grounding body. Then, the static electricity clamp 82 is reliably clamped on the metal exposed part of the accident tank truck or the metal frame of the air-cooled vaporizer 2, the grounding wire 83 connects the grounding needle 81 and the static electricity clamp 82, forming a complete grounding loop through which the static electricity charge accumulated on the equipment, vehicle body and operator is safely conducted to the ground, and the grounding resistance is strictly controlled below 2Ω, ensuring that the static electricity generated by the medium flow can be instantaneously conducted away, eliminating the risk of igniting the leaked flammable gas due to static electricity spark. This procedure also needs to be performed before the system is disassembled to ensure that the entire operation process is in a static electricity safe state.

[0032] In a further preferred embodiment of the present application, a wind direction follow-up mechanism for monitoring wind speed and adjusting the orientation of the combustion gun 1 is provided on the counterweight base 10. The wind direction follow-up mechanism comprises: a wind direction sensor 16 fixedly installed on the top of the counterweight base 10 for real-time monitoring of wind direction; and a rotation adjustment mechanism provided on the counterweight base 10 and the annular plate 14 for rotationally adjusting the orientation of the combustion gun 1.

[0033] In the present embodiment, after the system is powered on, the wind direction sensor 16 starts to continuously monitor the real-time environmental wind direction and transmits the signal to the remote control system. When the control system calculates that the current orientation of the combustion gun 1 has an included angle with the wind direction, the rotation adjustment mechanism is started. Since the combustion gun 1 is connected to the annular plate 14 through the support 11, the rotation of the annular plate 14 directly drives the combustion gun 1 to adjust its injection direction. This closed-loop adjustment process continues to ensure that the flame injection direction of the combustion gun 1 always coincides with the wind direction (downwind). This not only utilizes the wind to assist combustion, improves combustion efficiency and reduces black smoke and unburned gas emissions, but also ensures that the flame and hot flue gas are away from the operating area and the equipment body, maintains the stability of the flame, and avoids the risk of backfire caused by the flame being blown to one side of the equipment due to crosswinds.

[0034] In a further preferred embodiment of the present application, the rotation adjustment mechanism comprises: a gear ring 17 fixedly installed on the inner side of the annular plate 14; a driving gear 18 rotationally installed on the top of the counterweight base 10 and engaged with the gear ring 17; a motor 19 fixedly installed on the top of the counterweight base 10; and a set of first bevel gears 20 respectively installed on the output shaft of the motor 19 coupling and the rotating shaft of the driving gear 18, with the set of bevel gears 20 being engaged.

[0035] In the present embodiment, when the motor 19 is started, the output shaft of the motor 19 changes the power direction through the set of first bevel gears 20, drives the driving gear 18 to rotate, and the driving gear 18 is engaged with the gear ring 17, thereby driving the entire annular plate 14 to rotate smoothly on the counterweight base 10.

[0036] In the further preferred embodiment of the present application, the top of the counterweight base 10 is fixedly provided with an arc-shaped frame 21, the bottom of the annular plate 14 is fixedly provided with an arc-shaped rod 22 for sliding connection with the arc-shaped frame 21, and a plurality of supporting balls 23 are arranged in the arc-shaped frame 21 for supporting the arc-shaped rod 22.

[0037] In the present embodiment, when the annular plate 14 is rotated and adjusted under the driving of the motor 19, the arc-shaped rod 22 fixed to the bottom of the annular plate 14 slides in the track of the arc-shaped frame 21, and the plurality of supporting balls 23 arranged in the arc-shaped frame 21 are in rolling frictional contact with the bottom of the arc-shaped rod 22. By effectively transmitting and dispersing the total weight of the annular plate 14, the support 11 and the combustion gun 1 to the solid counterweight base 10 through the arc-shaped rod 22 and the supporting balls 23, not only the flexibility and low resistance of the annular plate 14 during rotation are ensured, but also the key load-bearing support is provided to prevent the annular plate 14 from sinking, deforming or being stuck due to long-term weight, and the reliability and stability of the wind direction following mechanism under long-term and frequent operation are ensured.

[0038] In the further preferred embodiment of the present application, the top of the counterweight base 10 is provided with a power storage device 24 for supplying power to the wind direction sensor 16 and the motor 19, and the power storage device 24 is located between the wind direction sensor 16 and the motor 19.

[0039] In the present embodiment, the power storage device 24 (such as a storage battery) provides power for the wind direction sensor 16 and the motor 19 after being deployed, constitutes a complete power and control chain, optimizes the wiring and reduces the line loss by placing the power storage device 24 between the wind direction sensor 16 and the motor 19. During the entire emptying and ignition operation, the power storage device 24 continuously discharges to ensure uninterrupted operation of the intelligent direction adjusting system. After the operation is completed, the power storage device 24 can be charged to prepare for the next operation.

[0040] In the further preferred embodiment of the present application, a connecting port is formed in the annular plate 14, the connecting port is located below the U-shaped clamping block 15, a reinforcing mechanism for reinforcing the support 11 is arranged on the annular plate 14, and the reinforcing mechanism comprises a connecting box 25 fixedly arranged on the bottom of the annular plate 14, a threaded rod 26 rotatably arranged in the connecting box 25, a threaded cylinder 27 threadedly arranged on the threaded rod 26 for fixing the bottom block of the support 11, the threaded cylinder 27 being matched with the connecting port and a clamping groove in the bottom of the bottom block, and a rotating rod 28 rotatably arranged in the connecting box 25, the rotating rod 28 and the threaded rod 26 being fixedly provided with a second bevel gear 29, and the two second bevel gears 29 being engaged with each other.

[0041] In the embodiment, after the bottom block of the support 11 is inserted into the U-shaped clamping block 15 to complete the preliminary positioning, the final rigid locking is performed, the operator rotates the handle 30, the rotation of the handle 30 is transmitted to the rotating rod 28 through the third bevel gear 31, the rotation of the rotating rod 28 is transmitted to the threaded rod 26 through the second bevel gear 29, since the threaded cylinder 27 is designed to be rectangular, it can only move up and down in the connecting box 25 and cannot rotate, therefore, when the threaded rod 26 rotates, the threaded cylinder 27 is driven to move linearly upward, the threaded cylinder 27 passes through the connecting port on the annular plate 14 upward, the top end thereof is accurately inserted into the preset clamping groove at the bottom of the bottom block, like a vertical bolt, the bottom block, the U-shaped clamping block 15 and the annular plate 14 are tightly locked together, and the anti-toppling capacity of the support 11 under complex wind load is greatly enhanced.

[0042] In the further preferable embodiment of the application, the handle 30 for driving the rotating rod 28 to rotate is rotatably installed on the annular plate 14, the rotating shaft of the handle 30 and the rotating rod 28 are both fixedly sleeved with the third bevel gear 31, the two third bevel gears 31 are engaged, and the threaded cylinder 27 is arranged in a rectangular shape.

[0043] In the embodiment, the threaded locking mechanism (the threaded rod 26 and the threaded cylinder 27) driven by the handle 30 rigidly locks the bottom block of the support 11 on the annular plate 14, the anti-toppling capacity of the combustion gun 1 under strong wind or vibration working conditions is greatly enhanced, the operation is simple and labor-saving, the locking is reliable, and the absolute stability of the core execution component under harsh environment is ensured.

[0044] In order to further improve the use effect of the device, in addition to the above-mentioned scheme, the present scheme also has the following embodiments: In another embodiment of the application, the top of the counterweight base 10 is fixedly installed with a fixed block 32, the fixed block 32 is rotatably installed with a protective cover 33 for protecting the power storage device 24 and the wind direction sensor 16, and the protective cover 33 covers the power storage device 24 and the wind direction sensor 16.

[0045] In the embodiment, in the device transportation or non-working state, the protective cover 33 is tightly covered on the power storage device 24 and the wind direction sensor 16 as a whole, effectively preventing dust and accidental collision from damaging these precise electrical elements, when the device arrives at the site and needs to be put into use, the operator can rotate the rotating handle 30 to integrally open the protective cover 33 like opening the lid of a box, so that the protective cover 33 rotates around the fixed point, thereby exposing the equipment below, and preparing for the power-on of the system and the starting of the sensor.

[0046] In another embodiment of the present application, the protective cover 33 is composed of two half covers, and each half cover is provided with a connecting gear 34 on the rotating shaft and the fixing plate 32, the two connecting gears 34 are engaged, and each half cover is further provided with a sprocket 35 fixed on the rotating shaft of the connecting gear 34 on the fixing plate 32, and the two sprockets 35 are provided with a chain 36, and each half cover is further provided with a linkage mechanism for synchronously driving the half cover and the rotating rod 28, and the fixing plate 32 is provided with a protective cover 42 for protecting the sprocket 35 and the connecting gear 34.

[0047] In this embodiment, when one half cover starts to rotate under the driving of external force, the connecting gear 34 on the rotating shaft immediately transmits the rotating motion to the other connecting gear 34 on the fixing plate 32, and due to the characteristics of the gear engagement, the rotating directions of the two connecting gears 34 are opposite, thereby directly driving the two half covers to rotate in the same direction (one clockwise and the other counterclockwise) or in the opposite direction, and through the combination of the sprocket 35 and the chain 36, the rotation of the rotating shaft of one half cover is accurately transmitted to the rotating shaft of the other half cover, thereby ensuring that the two half covers are synchronously opened or closed at the same angular velocity, and the entire gear and chain transmission system is shielded by the protective cover 42, thereby preventing the gear and chain transmission system from being blocked or damaged by foreign matters in a harsh field environment, and ensuring the reliability of the linkage opening mechanism.

[0048] In another embodiment of the present application, the linkage mechanism comprises a U-shaped block 37 fixedly installed on the rotating shaft of the half cover, a linkage rod 38 rotatably installed on one side of the connecting box 25, a rectangular block 39 fixedly installed on one end of the linkage rod 38 and inserted into the U-shaped block 37, and a differential bevel gear 40 fixedly installed on the other end of the linkage rod 38 and the rotating rod 28, and the two differential bevel gears 40 are engaged.

[0049] In this embodiment, when the operator rotates the handle 30 to lock the support 11, the rotating force is transmitted to the rotating rod 28 and the differential bevel gear 40, and the end of the linkage rod 38 is fixedly provided with a rectangular block 39 which is inserted into the U-shaped block 37 fixedly installed on the rotating shaft of one half cover, so that when the linkage rod 38 starts to rotate, the torque is directly transmitted to the rotating shaft of the half cover through the insertion of the rectangular block and the U-shaped block, thereby driving the half cover to start to rotate and opening the protective cover 33, and the operator only needs to perform one action of “rotating the handle 30 to lock the support 11”, thereby automatically and synchronously opening the two protective covers 33 when the combustion gun 11 is firmly fixed, so that the wind direction sensor 16 is completely exposed and immediately starts to work, and this integrated design greatly optimizes the operation steps, shortens the emergency response time, and ensures that the core sensing device can timely enter the working state.

[0050] Compared with the related art, the device is simple in operation, safe and reliable, efficient in disposal, flexible in material gas phase / liquid phase discharge, safe in remote ignition, and significantly reduces the tank pressure with fast emptying and burning efficiency, and provides a more advanced, active and reliable solution for emergency rescue of hazardous chemical accidents.
