How to eliminate static electricity in production process
There are two main ways to eliminate static electricity: First, to create conditions to speed up the electrostatic leakage or neutralization; Second, control the process to limit static electricity.
The first route includes two methods, namely, the spill method and the neutralization method. Grounding, humidification, antistatic agents, etc. are leaking method, the use of inductive static eliminator, high voltage static eliminator, radioactive static eliminator and ion current static eliminator are all neutralization method.
The second approach, the process control method, includes material selection, process design, equipment structure and operational management.
1, control the flow rate
Reduce the flow rate will reduce the degree of friction, can reduce the generation of static electricity. The amount of static electricity generated by the flow of oil in the pipeline is proportional to the square of the flow rate of the oil, so controlling the flow rate is an effective way to reduce the generation of electrostatic charge.
2, control refueling methods
To avoid liquid splashes and impacts in the container, fill the bottom or extend the tubing close to the bottom of the container. General provisions, crane tube before immersion, the flow rate can only be limited to 1m / s or less, immersion and then according to the recommended flow rate canned.
3, to speed up the dissipation of electrostatic charge
4, eliminate the additional source of static electricity
5, choose a reasonable material
6, closed segmentation method
Elimination of human static electricity
Elimination of human static electricity, the use of grounding, wearing anti-static shoes, anti-static overalls and other specific measures to reduce the accumulation of static electricity in the human body. To ensure safe operation, in the work, try not to do with the human body charged things. If not close to or contact with charged body, do not wear in the workplace, take off the work clothes. Do not carry work-related metal objects, such as keys, coins, watches, rings, etc., when operating in hazardous locations with static electricity.
