The Human Factors That Cause Liquid Nitrogen Accidents

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2017-09-12
         The Human Factors That Cause Liquid Nitrogen Accidents
         ① Improper Storage And Transportation
         Liquid nitrogen tank storage types can be divided into two kinds of storage tanks and transport tanks. Storage tank is mainly used for indoor liquid nitrogen storage, should not be used in the working state for the use of distance transport.
         ② Improper Use
         Long-term use of liquid nitrogen tank, if the use of the operation process is not done regularly maintenance inspection and maintenance, equipment will be insecure, may cause an explosion. In the operation of liquid nitrogen tank, if the exhaust valve is not open or open enough, liquid nitrogen after a long period of natural evaporation, the inner cylinder pressure. At this point if there is no safety protection device, the pressure continues to rise, it may lead to the bottom of the supercharger tube to take over the original defects at the crack. Once the liquid nitrogen leaks into the sandwich space after gasification, sandwich pressure increases rapidly, it will lead to the outer cylinder explosion. Part of the Tianchi liquid nitrogen tank control staff without safety education, only the teacher oral teaching skills after induction manipulation, safety and skills and poor skills, but also prone to accidents.
         ③ Liquid Nitrogen Leakage
         In the liner of the liquid nitrogen can not be a long-term normal discharge, or a lot of leakage to the sandwich space gasification, may also lead to liquid nitrogen container explosion.
