As we all know, centrifuges are widely used in the chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors, especially in the chemical, pharmaceutical and other industrial sites.
When the centrifuge is running at high speed, static sparks will be generated. If the materials inside contain flammable and volatile gases such as alcohols, benzenes, lipids, etc., there will be a safety hazard of explosion.
At present, most of the solutions in the industry are to replace with nitrogen. The length of the replacement is based on production experience, the second is to see the nitrogen pressure value, and the third is to continuously carry out nitrogen charging protection; however, the above-mentioned solutions The method is not scientific, it is impossible to accurately feedback the value of oxygen in the centrifuge, or it causes a waste of nitrogen resources, resulting in frequent occurrence of centrifuge explosion accidents.
