Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of decontamination vehicles, in particular to a chemical decontamination vehicle for chlorine leakage rescue and disposal. BACKGROUND

[0002] With the continuous advancement of industrialization, chlorine, as a key raw material widely used in chemical industry, pharmaceutical industry and water treatment, etc., its leakage accidents occur from time to time. Chlorine has strong irritancy and toxicity, once leaked, not only poses a serious threat to the life safety of on-site workers, but also causes great harm to the environment. Therefore, fast and effective emergency disposal measures become an important means to ensure safety.

[0003] The traditional chlorine leakage emergency treatment method mainly relies on single-point high-pressure jet equipment for chemical neutralization and dilution, although it can slow down the diffusion of harmful gas to a certain extent, but it has the problems of limited spraying range, insufficient coverage area, difficulty in dealing with complex leakage area shape and wind direction change, etc. In addition, the traditional decontamination vehicle adopts shower type spraying, which needs personnel to constantly adjust the angle of the spray head during operation, which is complicated and low in efficiency, and it is difficult to achieve all-around, dead-angle-free cleaning and coverage.

[0004] In recent years, with the development of emergency technology, water curtain barrier as an effective means to block the diffusion of gas has been gradually applied to the control of harmful gas leakage. The water curtain can form a continuous barrier to block the diffusion path of harmful gas, significantly reduce the diffusion speed in the leakage area, and enhance the safety protection on site. However, the existing water curtain system is mostly fixed or simple adjustment structure, lacking dynamic adjustment ability, which is difficult to adapt to the changing leakage environment and wind direction on site, limiting its actual application effect.
