Embodiment

[0028] An ammonia leakage decontamination simulation experiment platform of the present invention includes an ammonia metering system, a gas circulation system, a data collection and analysis system, a fine water mist system, and a decontamination room.

[0029] (1) Water mist system

[0030] ① Selection of decontamination methods

[0031] Considering that the leakage of ammonia gas volatilizes and diffuses very quickly, the selected decontamination method must have the characteristics of rapidity. In recent years, more and more water mist fire extinguishing equipment has been used in the fire fighting practice of firefighting forces. Various water mist fire extinguishing devices and equipment emerge in endlessly, including portable water mist fire extinguishing devices, backpack type water mist fire extinguishing devices, vehicle-mounted water mist fire extinguishing Water mist firefighting motorcycles, bread-type water mist fire trucks, elevated (remote) water mist fire tr...

experiment example

[0069] In order to test the reliability and tightness of the decontamination experimental device and the working conditions of each system, the decontamination test is carried out. After three parallel experiments, the reproducibility was very good, as Figure 7 shown.

[0070] Depend on Figure 7 It can be seen that the change curves of the ammonia concentration with the decontamination time in Experiments 1, 2 and 3 basically overlap, and the decontamination time is 137s, 133s, and 134s respectively, and the difference is small. Therefore, this experimental device has good reproducibility in the study of ammonia simulated decontamination.

Description

Technical field [0001] The invention relates to a simulation experiment platform, in particular to an ammonia leakage decontamination simulation experiment platform Background technique [0002] Ammonia is a widely used chemical raw material. Due to its high toxicity and high pollution, once leakage occurs, it can easily cause poisoning of personnel, environmental pollution, and even major fire and explosion accidents. Emergency response after ammonia leakage is a key measure to reduce its harm. Decontamination is an extremely important technical method in emergency response, which can effectively prevent the spread, remove residues, and reduce harm. Therefore, the design and construction of an ammonia leak decontamination simulation experimental platform can provide an important platform for studying ammonia leak decontamination and treatment. [0003] The design and establishment of the ammonia decontamination experimental device is to establish a good decontamination ex...
