Devices Based on Liquid Nitrogen for Rapid Freezing of Man-Made Pollution with Subsequent Disposal and Fire Extinguishing
It is proposed to use the cryogenic freezing method for localizing and eliminating the effects of man-made pollution with their subsequent disposal, as well as for fire fighting. For these purposes, a cryogenic modular device has been developed using liquid nitrogen gas, which is formed as a result of its evaporation. Also developed a spray device of the "pistol" type, which allows to implement the proposed method based on freezing pollution in hard-to-reach places, or in places with complex surface relief. A prototype of the "pistol" was made and tests were carried out to prove its effectiveness.
