MIBK tank anti-static grounding device installation specification

In the chemical industry, the harm of static electricity can not be ignored, especially in the storage and transportation of flammable and explosive liquids. MIBK (methyl isobutyl ketone) is a flammable organic solvent, which is widely used in coatings, adhesives, electronic cleaning and other fields. Due to its flammable nature, static electricity accumulation may cause serious safety hazards. Therefore, in the design and installation of MIBK storage tanks, the standardized use of anti-static grounding devices is very important. This article will introduce the installation specification of MIBK tank anti-static grounding device in detail to help chemical enterprises to ensure safe production.

1. MIBK tank anti-static grounding device design principles

When designing the anti-static grounding device of the MIBK tank, the following basic principles need to be followed:

1. Grounding resistance requirements The grounding resistance of the anti-static grounding device shall be controlled within 100Ω. Excessive resistance will lead to the accumulation of static electricity, which cannot effectively eliminate static electricity, while too small resistance may cause unnecessary electrochemical corrosion to the equipment.

2. Selection of grounding position For MIBK tanks, anti-static grounding devices should be installed at key positions such as the inlet and outlet pipes, top and bottom of the tank to ensure that static electricity can be quickly released through these parts.

3. Material selection The material of the grounding device should have corrosion resistance and good conductivity. Corrosion resistant materials such as stainless steel and galvanized steel are recommended to cope with the chemical nature of MIBK.

4. Connection with tank The earthing device shall be tightly connected to the tank body to ensure effective current conduction. It is recommended to use bolts or welding to avoid poor contact or looseness.

2. MIBK tank anti-static grounding device installation steps

1. Determine the grounding position First of all, it is necessary to determine the installation position of the grounding device according to the structure and function of the storage tank. The inlet and outlet, top and bottom of the tank are usually selected as grounding points to ensure that static electricity can be quickly released from these parts.

2. Select the appropriate grounding body According to the use of the storage tank environment and soil conditions, select the appropriate grounding body. Common grounding bodies include angle steel, steel pipes, etc., and the buried depth is generally 0.5 meters to 1 meter.

3. Treatment of tank surface Prior to the installation of earthing devices, the surface of the tank shall be cleaned and treated to ensure that the earthing device is in full contact with the tank. If necessary, conductive paste or anti-rust paint can be used to enhance the conductivity.

4. Connecting lead Connect the grounding device to the grounding point on the tank using a multi-strand copper conductor with a cross-sectional area of more than 10mm ². The connection of the wire should be welded or crimped to ensure good contact.

5. Detection of grounding resistance After installation, the resistance of the grounding device shall be tested with a grounding resistance tester. Ensure that the grounding resistance meets the design requirements, usually below 100Ω.

3. MIBK tank anti-static grounding device daily maintenance

1. Regularly check the grounding device In order to ensure the long-term effectiveness of the anti-static grounding device, it is recommended to check the device every 6 months. Focus on checking whether the wire connection is loose, whether the grounding body is corroded, and whether the conductivity is reduced.

2. Clean up the surrounding debris Ensure that the environment around the grounding device is clean to avoid debris blocking or affecting the conductivity.

3. Re-test ground resistance After each check, retest the grounding resistance to ensure that it is within the specified limits. If it is found that the grounding resistance exceeds the standard, the grounding body should be adjusted or replaced in time.

4. Considerations

1. Operate in strict accordance with specifications When installing and maintaining the anti-static grounding device, it must be operated in strict accordance with the relevant specifications. Any random changes or negligence may lead to the accumulation of static electricity, causing safety hazards.

2. Training professionals The installation and maintenance of anti-static grounding devices need to be completed by professionals. Enterprises should regularly train relevant personnel to ensure that they are familiar with the use and maintenance methods of the device.

3. Record inspection and maintenance data It is recommended to establish detailed operation records, including the time of each inspection, grounding resistance value, maintenance content, etc. These records can provide reference for subsequent equipment maintenance and hidden trouble investigation.

Conclusion The anti-static grounding device of MIBK storage tank is an important facility to ensure the safe production of chemical enterprises. Through scientific design, standardized installation and regular maintenance, the potential safety hazard caused by electrostatic accumulation can be effectively avoided. It is hoped that the introduction of this paper can provide valuable reference for relevant practitioners to ensure the safe operation of storage tanks.
