Description

Technical Field

[0001] This utility model relates to the field of gas safety technology, specifically a gas leak simulation device for gas emergency drills. Background Technology

[0002] Gas (mainly including piped natural gas, liquefied petroleum gas, etc.) is a clean and efficient energy source that has been widely used in residential life, industrial and commercial production and urban operation. However, gas is flammable, explosive and toxic (such as carbon monoxide). Once a leak occurs, it can easily cause serious accidents such as fire, explosion and poisoning, which seriously threaten the safety of people's lives and property and social stability.

[0003] To effectively respond to gas leak accidents and minimize losses, it is crucial to conduct regular, realistic gas leak emergency drills. However, traditional drill methods have significant technical limitations and safety challenges.

[0004] 1. Using real gas for drills (which has been largely prohibited): This is the most dangerous method. Even with strict safety measures, it is impossible to completely eliminate the risk of explosions or fires caused by ignition sources, static electricity, etc. It poses a huge threat to participants, observers and the surrounding environment. Moreover, the cost of drills is high and is greatly restricted by the venue. Therefore, for safety reasons, it is strictly prohibited to use real gas for large-scale emergency drills outside of uncontrolled professional experimental environments.

[0005] II. Using a smoke generator for simulation: This is a relatively common alternative method currently used. It uses non-toxic and harmless simulated smoke (such as ethylene glycol smoke, atomized water vapor, etc.) to indicate the location and spread of the "leak." However, its disadvantages are also obvious:

[0006] 1. Poor realism: The physical properties of smoke (such as density, diffusion speed, rising / falling trend) are significantly different from those of natural gas (mainly methane, which is lighter than air), making it impossible to realistically simulate the leakage, accumulation, and diffusion behavior of different types of gas (such as key phenomena like diffusion along the ceiling).

[0007] 2. Odorless simulation: It cannot simulate the odor of warning odorants added to the gas (such as tetrahydrothiophene THT), and odor identification is an important sensory clue for on-site personnel to detect leaks. Utility Model Content

[0008] The purpose of this invention is to provide a gas leak simulation device for gas emergency drills, in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A gas leak simulation device for gas emergency drills includes a high-pressure inert gas tank. A valve 1 connected to the lower end of the right side surface of the high-pressure inert gas tank is fixedly connected to the lower end of the tank, and a valve 2 connected to the upper end of the left side surface of the high-pressure inert gas tank is fixedly connected to the upper end of the tank. A pipe 1 is fixedly connected to the left end of the valve 2, a valve 3 is fixedly connected to the left end of the pipe 1, and a pipe 2 is fixedly connected to the left end of the valve 3.

[0011] An odor control device is located on the left side of the high-pressure inert gas tank.

[0012] As a further embodiment of this utility model: the odor mechanism includes a storage tank, a delivery pump is fixedly connected to the upper surface of the storage tank, a pipe three is fixedly connected to the input end of the delivery pump, and a pipe four is fixedly connected to the output end of the delivery pump. A valve four is fixedly connected to the left end of the pipe four, a pipe five is fixedly connected to the left end of the valve four, and an atomizing nozzle is fixedly connected to the left end of the pipe five.

[0013] As a further embodiment of this utility model: a leakage component is provided at the left end of the second pipe. The leakage component includes a fixed plate, a threaded ring is fixedly connected to the right side surface of the fixed plate, and a leakage pipe is fixedly connected through the left side surface of the threaded ring.

[0014] As a further embodiment of this utility model: the liquid storage tank is located to the left of the high-pressure inert gas tank, the third pipe is fixedly connected to the upper surface of the liquid storage tank, the fifth pipe is fixedly connected to the lower left end of the second pipe, and the atomizing nozzle is located inside the second pipe.

[0015] As a further embodiment of this utility model: the fixing plate is attached to the left end of the second pipe, the threaded ring is threadedly connected to the inside of the second pipe, and the leakage pipe is located inside the threaded ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses nitrogen released from a high-pressure inert gas tank as a safety carrier. After pressure regulation by a pressure reducing valve, it is fully mixed with a safety odorant drawn by a delivery pump and atomized by an atomizing nozzle within the pipeline. Finally, a detachable leak device is used to release the mixture in a directional manner to simulate a leak. Compared to traditional real gas drills, this completely eliminates the risk of combustion and explosion. Compared to smoke simulation methods, it not only provides a visual diffusion effect but also accurately reproduces the irritating odor characteristics of a gas leak through precise odorant mixing, solving the deficiency of smoke simulation in conveying odor warnings. At the same time, the leak device can be flexibly directed to different leak scenarios (such as pipe cracks or interface breaks), greatly enhancing the immersion and practical relevance of the drill. Furthermore, the entire device has no electrical spark hazards and complies with flammable environment safety regulations. Attached Figure Description

[0023] Please see Figure 1 and Figure 2 In this embodiment of the present invention, a gas leak simulation device for gas emergency drills includes a high-pressure inert gas tank 1. A valve 2 connected to the lower end of the right side surface of the high-pressure inert gas tank 1 is fixedly connected to the lower end of the tank, and a valve 3 connected to the upper end of the left side surface of the high-pressure inert gas tank 1 is fixedly connected to the upper end of the tank, a pipe 4 is fixedly connected to the left end of the valve 3, a valve 5 is fixedly connected to the left end of the pipe 4, and a pipe 6 is fixedly connected to the left end of the valve 5.

[0024] An odor mechanism 7 is provided to the left of the high-pressure inert gas tank 1. The odor mechanism 7 includes a storage tank 8, which is located to the left of the high-pressure inert gas tank 1. A delivery pump 9 is fixedly connected to the upper surface of the storage tank 8. A pipe 3 10 is fixedly connected to the input end of the delivery pump 9. The pipe 3 10 passes through and is fixedly connected to the upper surface of the storage tank 8. A pipe 4 11 is fixedly connected to the output end of the delivery pump 9. A valve 4 12 is fixedly connected to the left end of the pipe 4 11. A pipe 5 13 is fixedly connected to the left end of the valve 4 12. The pipe 5 13 passes through and is fixedly connected to the left end of the lower surface of the pipe 2 6. An atomizing nozzle 14 is fixedly connected to the left end of the pipe 5 13. The atomizing nozzle 14 is located inside the pipe 2 6.

[0025] The high-pressure inert gas tank 1 includes a tank body and a tank cover fixed to the upper end of the tank body, which can be fixed together by bolts;

[0026] A pressure gauge connected to the inside of the can is fixed to the can lid;

[0027] The high-pressure inert gas tank 1 is filled with high-pressure inert gas.

[0028] Both valve 1 (2) and valve 2 (3) are shut-off valves; valve 1 (2) is used for filling high-pressure nitrogen into high-pressure inert gas tank 1; valve 2 (3) is used for discharging high-pressure nitrogen.

[0029] Valve 3.5 is a pressure reducing valve, used to reduce the pressure of discharged nitrogen gas;

[0030] The storage tank 8 is filled with a safe odorant, such as a tetrahydrothiophene (THT) simulant solution;

[0031] The delivery pump 9 is preferably a variable frequency water pump, which can adjust the flow rate and is used to extract the safe odorant.

[0032] Valve 4.12 is a stop valve;

[0033] The atomizing nozzle 14 is used to atomize the output safety odorant and mix it with nitrogen gas to simulate the warning smell of a real gas leak.

[0034] exist Figure 1 , Figure 3 and Figure 4 In the middle: A leakage element 15 is provided at the left end of the second pipe 6. The leakage element 15 includes a fixed plate 16. The fixed plate 16 is attached to the left end of the second pipe 6. A threaded ring 17 is fixedly connected to the right side surface of the fixed plate 16. The threaded ring 17 is threadedly connected to the inside of the second pipe 6. A leakage pipe 18 is fixedly connected through the left side surface of the threaded ring 17. The leakage pipe 18 is located inside the threaded ring 17.

[0035] The leak pipe 18 is a flexible hose, the end of which can be connected to a simulated "ruptured pipe" or "valve interface".

[0036] The working principle of this utility model is as follows: The operator first opens valve 23 to release the high-pressure nitrogen in the high-pressure inert gas tank 1. The gas flow enters valve 35 through pipeline 14 (for depressurization); simultaneously, the delivery pump 9 is started to extract the safety odorant from the storage tank 8, and delivers it to the atomizing nozzle 14 through pipeline 310 → pipeline 411 → valve 412 → pipeline 513. The atomized odorant is fully mixed with the depressurized nitrogen in pipeline 26. When the mixed gas flows to the left end of pipeline 26, it is released directionally through the detachable leaking part 15 (composed of a fixed plate 16, a threaded ring 17, and a leaking pipe 18). The end of the leaking pipe 18 points to the simulated leak point (such as a pipe crack). The trainees perceive the odor of the odorant through their sense of smell, realistically simulating the sound and smell of a gas leak. After the exercise, valve 23, delivery pump 9, and valve 412 are closed in sequence.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
