氨制冷机房门开启位置对氨气泄漏摩尔浓度的影响
Effect of opening position of ammonia cold storage refrigeration room door on ammonia leakage concentration
摘要
Abstract
The actual ammonia refrigeration plant room was used as a reference simulation object to explore the diffusion law of ammonia concentration under different relative positions of plant room doors.According to the different impact of ammonia on the human body,different leakage times were selected for comparative analysis of ammonia concentration,and it was concluded that in the case of 1.6 m height,the operator has about 37 s time to escape when the two doors of the refrigeration room were set on two adjacent walls,and about 33 s time to escape when the doors of the two rooms were opened relative to each other;ammonia touched the wall and bounces to form a vortex,and opening the doors of the two rooms relative to each other will make the vortex position change,accelerate the speed of ammonia diffusion,is not conducive to the safe escape of operators and other conclusions.The relative position of the two machine room doors of the cold storage was reasonably suggested,so as to prevent the operator′s life safety and property damage caused by gas poisoning.关键词
