The three elements that cause an explosion are temperature, fire source and oxygen. The simultaneous existence of the three basic conditions for preventing chemical explosions is the fundamental theory for preventing chemical explosions of flammable substances. In other words, the essence of all technical measures to prevent chemical explosions of flammable substances lies in the simultaneous existence of the three basic conditions for stopping chemical explosions.

Among them:

(1) Temperature: For a specific medium, whether in liquid or gas phase, the working temperature of the centrifuge should be taken into account during process design. This mainly depends on the process conditions and will not be analyzed in detail here.
(2) Fire source: When designing a centrifuge, sufficient safety space should be provided between moving parts to eliminate possible mechanical friction and impact. At the same time, the machine must have measures to eliminate static electricity. For braking devices, mechanical friction braking devices must not be used. Generally, electrical energy consumption braking is adopted (non-contact braking, the disadvantage is that the braking time is a little longer than that of contact braking, especially when the moment of inertia is large under full load). In addition, for the transmission belt, anti-static belts are selected to eliminate or reduce the possibility of static electricity generation.
(3) Oxygen is generally protected by inert gas. Nitrogen is filled into the centrifuge to displace the air inside, thereby maintaining the oxygen concentration within a safe range.
