Description

Technical Field

[0001] The utility model relates to the technical field of tank truck accident disposal, in particular to a tank truck accident disposal device. Background Art

[0002] Tank truck accident handling is an important task involving venting, ignition, plugging, tank dumping and nitrogen injection. In tank truck accidents, common response measures include venting, ignition, plugging, tank dumping and auxiliary nitrogen injection. Venting technology is usually divided into gas phase venting and liquid phase venting, which aims to reduce the pressure inside the tank and reduce the risk of leakage and explosion. Ignition technology reduces the risk of diffusion and explosion of hazardous chemicals by controlling the ignition point. Leakage plugging technology is to seal or repair the leak point to prevent further leakage and environmental pollution. Tank dumping technology is to transfer the materials in the accident tank truck to a safe container to reduce the source of danger and fire load. Auxiliary nitrogen injection technology reduces the oxygen concentration inside the tank by injecting nitrogen into the accident tank to reduce the risk of fire and explosion.

[0003] However, the existing technology has some disadvantages in the process of handling tank truck accidents:

[0004] Venting technology: The venting process takes a long time and cannot quickly reduce the pressure inside the tank, increasing the risk of leakage and explosion. The venting effect on high-pressure liquids is limited and cannot effectively control leakage. The venting of volatile liquids or gaseous substances may cause environmental pollution and personnel exposure risks.

[0005] Ignition technology: The ignition process may produce open flames and high temperatures, increasing the risk of fire and explosion. Some hazardous chemicals may produce toxic gases or harmful substances during the ignition process, causing further harm to the environment and personnel.

[0006] Plugging technology: The selection and use of plugging agents are limited, and different hazardous chemicals have different applicability to plugging agents. Plugging agents may not completely plug the leak point, causing the leak to continue or reoccur.

[0007] Canning Technology: The canning process requires specialized equipment and operators and may not be suitable for complex or difficult situations. The canning process may cause secondary contamination, especially if accidents or operating errors occur during the transfer process.

[0008] Nitrogen injection technology: Prior art CN102562125B discloses a ground direct injection liquid nitrogen fire extinguishing system, in which the outlet of the liquid nitrogen tank truck is connected to the inlet of a reciprocating cryogenic liquid pump, the outlet of the reciprocating cryogenic liquid pump is connected to the liquid inlet on the upper part of the buffer tank, the liquid outlet at the lower part of the buffer tank is connected to a vacuum cryogenic insulation pipe, the vacuum cryogenic insulation pipe is connected to the nitrogen injection pipe and the nitrogen delivery pipe, the exhaust port at the upper end of the buffer tank is connected to the nitrogen delivery pipe, the upper part of the buffer tank is a single-layer shell, and the upper end of the buffer tank is connected to a pressure relief valve. The key technical problems of gas-liquid two-phase separation after liquid nitrogen vaporization and avoiding blockage of the nitrogen injection pipe are solved. However, such existing nitrogen injection devices are difficult to mobilize a large amount of nitrogen sources at one time. At the same time, the nitrogen injection process requires a large amount of nitrogen supply, and the preparation and transportation costs of nitrogen are high, especially in large-scale accident disposal. It takes a long time, and the nitrogen injection process requires a certain amount of time to inject nitrogen into the tank, so it is impossible to quickly reduce the oxygen concentration and pressure inside the tank, and delay the combustion or explosion risk of hazardous chemicals.

[0042] Preparation:

[0043] When a tank truck accident occurs, the device is quickly deployed to the accident site. Ensure that the water storage tank 201 of the fire control assembly 20 in the mobile fire control component 2 is filled with water, and connect the fire water pipe interface 203 and the fire hose interface 204 to the pipe to provide water.

[0045] Ignite items and control combustion safely:

[0046] The torch assembly 10 and the ignition assembly 11 in the ignition component 1 are used to quickly ignite the materials in the tank truck.

[0047] The flame nozzle 103 in the torch assembly releases flames to ignite the materials in the tank truck.

[0048] 3. Monitoring and control adjustment:

[0049] The operator monitors the combustion conditions to ensure the stability and safety of the combustion process, and adjusts the water mist spray volume of the water mist nozzle as needed to maintain the control effect of the combustion process to achieve the best safety control effect.

[0050] 4. Complete the disposal:

[0051] After ensuring that the materials in the tank truck have been completely burned and controlled, the operator can stop the spraying of flames and water mist, wait for the flame to be extinguished, conduct necessary inspections and cleaning work, rotate the flare assembly 10 and the ignition assembly 11 to separate them, and rotate the threaded positioning protrusion 102 of the detachable flare tube body 101 from the threaded groove 114 of the electric valve seat 112 to separate them, and place the detachable flare tube body 101 in the U-shaped groove 32 of the positioning card plate 31 of the positioning box 3, separate the fire water pipe interface 203 and the fire hose interface 204 connecting the pipes from the loading and unloading port of the tank truck, and drive the locking pin 216 to rotate by rotating the steering knob 218, thereby driving the arc-shaped locking block 214 to rotate, thereby disengaging from the bottom of the folding gripping handle 208, and while the locking pin 216 rotates, it drives the radial locking pin 220 to rotate to the axial position, thereby entering the axial pin groove 219 on the inner edge of the locking nut 217, so that the folding gripping handle 208 is folded.
