Controlling Speed to Prevent Static Electricity
In industrial production, static electricity is a constant and potentially dangerous problem. Static electricity control requires both hardware and software measures, and constant vigilance is essential during production. There can be no room for carelessness in dealing with static electricity.
In industrial processes, static electricity can be generated through friction between two objects, gradually accumulating and potentially causing electrostatic hazards. Therefore, reducing the friction speed can slow down the generation of static electricity, achieving the goal of preventing electrostatic hazards. In industrial processes, due to limitations in material properties and production volume requirements, speed-limiting methods for preventing electrostatic hazards are commonly used in the transportation of flammable liquids. When transporting raw liquids/materials to storage tanks or containers, if the liquid is a flammable liquid with a low conductivity (less than 50 pS/m) and contains incompatible substances such as suspended solids and water, the flow rate of the flammable liquid should be limited to below 1 m/s during on-site operations.
If the flammable liquid does not contain incompatible substances, the flow rate should be limited to below 7 m/s. Most industrial processes are designed and operated according to this principle. Splashing caused during the feeding of flammable liquids with low conductivity is also a potential source of electrostatic hazards in the process. To mitigate this, the liquid feed line should be placed as close as possible to the bottom of the storage tank/container, or the liquid raw material should be transported via a feed line at the bottom of the storage tank/container. Alternatively, the flow rate of the flammable liquid should be reduced. The main purpose is to reduce friction and disturbance as the liquid crosses the surface, thereby avoiding the generation of excessive static electricity due to excessive friction.
