Specification for installation of anti-static grounding devices for propylene oxide storage tanks?

In the chemical industry, propylene oxide is an important basic chemical raw material, which is widely used in plastics, textiles, coatings and other fields. Because propylene oxide has the characteristics of flammability, explosion and oxidation, special attention should be paid to the accumulation and discharge of static electricity during the use of storage tanks. If static electricity is not controlled, it may cause serious safety accidents. Therefore, the installation specification of anti-static grounding device for propylene oxide storage tank is particularly important.

1. of Propylene Oxide Storage Tank Anti-Static Grounding Device

The main function of the anti-static grounding device is to prevent the accumulation of static electricity from causing sparks or other dangerous situations by safely discharging the static charge on the tank. For propylene oxide storage tanks, the generation of static electricity mainly comes from the flow of materials during storage, stirring or liquid surface fluctuations. If the static electricity is not discharged in time, it may cause electrostatic discharge, which may cause a fire or explosion accident. Therefore, the installation of anti-static grounding device is one of the important measures to ensure the safe operation of the storage tank.

1. Selection of installation location When installing the anti-static grounding device, it is necessary to select the appropriate installation position. Generally, the grounding device should be installed in the main part of the tank to ensure a good electrical connection with the tank. The grounding device should be far away from the discharge port and the feed port of the storage tank to avoid electrostatic interference during the flow of materials.

2. Selection of grounding device The material and structure of the grounding device shall meet the environmental requirements of the propylene oxide storage tank. Generally speaking, the grounding device should use corrosion resistance, good electrical conductivity materials, such as galvanized steel or stainless steel. The grounding resistance of the grounding device shall meet the relevant industry standards, and the grounding resistance is usually not greater than 10Ω.

3. Installation steps (1) During tank foundation construction, earthing flat iron shall be embedded around the tank. (2) Fix the grounding device on the outer wall of the storage tank and connect it with the grounding flat iron through a wire. (3) Ensure that the grounding device is in good contact with the tank body, and use conductive glue or metal gaskets when necessary. (4) After the installation is completed, test the grounding resistance with a megohmmeter to ensure that it meets the requirements.

4. Regular inspection and maintenance The anti-static grounding device needs to be checked regularly to ensure that it is in good condition. The inspection contents include: whether the connection is loose, whether the wire is damaged, whether the grounding resistance exceeds the standard, etc. If any abnormality is found, it should be handled in time to avoid potential safety hazards.

After the installation of the anti-static grounding device of the propylene oxide storage tank is completed, daily maintenance and management are required. The connection of the grounding device should be checked regularly for looseness or corrosion. The grounding resistance needs to be tested regularly to ensure that it is within the specified range. If it is found that the grounding resistance exceeds the standard, the cause should be found and dealt with in time. Also avoid stacking debris around the grounding device to prevent affecting its normal operation.

4. summary

The installation specification of anti-static grounding device for propylene oxide storage tank is an important link to ensure the safe operation of storage tank. Through scientific and reasonable installation and maintenance, it can effectively prevent safety accidents caused by static electricity accumulation and ensure the safe operation of propylene oxide storage tanks. In actual operation, it should be strictly implemented in accordance with relevant specifications and standards, and appropriate adjustments should be made in accordance with specific conditions to achieve the best safety effect.
