Specification for installation of anti-static earthing device for bisphenol A storage tank

in the chemical industry, bisphenol A is an important basic chemical raw material, which is widely used in the production of plastics, epoxy resin and polycarbonate. Because bisphenol A is flammable and volatile, it is easy to cause fire or explosion accidents due to static electricity accumulation when stored in storage tanks. Therefore, the installation specification of anti-static grounding device for bisphenol A storage tank is particularly important, which is one of the key measures to ensure the safe operation of the storage tank.

What is the anti-static grounding device of bisphenol A storage tank?

The anti-static grounding device is a safety device specially used to prevent the accumulation of static electricity. In the liquid storage tank, when the liquid flows, stirs or enters and exits the pipeline, it is easy to generate static electricity due to friction. If it is not released in time, the accumulation of static electricity to a certain extent may cause sparks, resulting in fire or explosion accidents. The anti-static grounding device ensures that static electricity can be safely released by introducing static electricity into the ground, thereby eliminating potential safety hazards.

Specification for installation of anti-static earthing devices

1. The harm of static electricity and the necessity of anti-static grounding

the liquid in the bisphenol A storage tank will generate static electricity during the flow or stirring process. The generation of static electricity is not only related to the nature of the liquid, but also closely related to the material of the storage tank and the flow rate of the liquid. When static electricity accumulates to a certain extent, it may cause electrostatic discharge (ESD,Electrostatic Discharge), which may cause a fire or explosion accident. Therefore, the installation of anti-static grounding device is a necessary measure to prevent electrostatic hazards.

2. Design and selection of anti-static grounding device

when choosing an anti-static grounding device, the following key factors need to be considered:

• material selection: The grounding device shall be made of materials with good corrosion resistance and electrical conductivity, such as stainless steel or galvanized steel.
• Installation position: The grounding device is usually installed at the bottom or side of the storage tank to ensure reliable contact with the tank.
• electrostatic conduction path: The grounding device should have good conductivity to ensure that static electricity can be quickly and safely discharged.

3. Precautions during installation

the installation of the anti-static grounding device of the bisphenol A storage tank needs to be carried out in strict accordance with the specifications to ensure the installation quality. The following are the considerations during installation:

• ground resistance test: After the installation is completed, the grounding resistance must be tested to ensure that the resistance value meets the relevant standards (usually not greater than 100 ohms).
• Use of electrostatic conductive materials: When installing grounding devices at the bottom or side of the storage tank, electrostatic conductive materials should be used to ensure that static electricity can be effectively conducted.
• Fixing and sealing: The grounding device should be firmly fixed on the storage tank and ensure the sealing performance to avoid effective discharge of static electricity due to loosening or leakage.

4. Regular inspection and maintenance

the performance of the anti-static grounding device will be affected by environmental factors, so it needs regular inspection and maintenance:

• periodic testing: Test the grounding resistance at regular intervals to ensure that it meets the standard.
• Cleaning and Inspection: Regularly clean the dirt and impurities around the grounding device to ensure that its conductivity is not affected.
• Replacement and repair: If the grounding device is found to be damaged or its performance is degraded, it should be replaced or repaired in time.

Conclusion

the installation specification of anti-static grounding device for bisphenol A storage tank is an important link to ensure the safe operation of the storage tank. Through scientific design and selection, standardized installation and regular inspection and maintenance, electrostatic hazards can be effectively prevented to ensure the safety and stability of the storage tank. When selecting anti-static grounding devices, chemical companies should combine their own actual conditions, select products that meet the standards, and install and maintain them in strict accordance with the specifications, so as to provide a strong guarantee for safe production.
