Embodiment

[0028] A novel 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 chamber.

[0029] (1) Fine 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 fire fighting motorcycles, bread type water mist fire trucks, elevated (remote) wate...

experiment example

[0068] In order to test the reliability and sealing 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.

[0069] 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 a simulation experiment platform for ammonia leak decontamination Background technique [0002] Ammonia is a widely used chemical raw material. Due to its high toxicity and high pollution, once leakage occurs, it is very easy to cause personnel poisoning, environmental pollution, and even cause major fire and explosion accidents. Emergency treatment after ammonia leakage is a key measure to reduce its hazards. Decontamination is an extremely important technical method in emergency treatment, which can effectively prevent diffusion, remove residues, and reduce hazards. Therefore, the design and construction of the simulation experiment platform for ammonia leak decontamination can provide an important platform for the study of ammonia leak decontamination and disposal. [0003] The design and establishment of the ammonia gas decontamination experimental device is to establish ...
