Problems solved by technology

Since the equipotential connection line is located in the confined space between the floating plate and the tank roof, it is neither easy to check nor easy to detect, so it is impossible to determine whether the equipotential connection line is well connected, which brings a huge hidden danger to the safe operation of the storage tank. It is easy to cause the charge accumulation of the storage tank to cause fire, which seriously threatens the safe operation of the external floating roof tank

Embodiment Construction

[0016] The invention provides an equipotential connection method between a floating plate and a tank roof of an inner floating roof storage tank, which comprises an inner floating plate and a tank roof manhole, and an equipotential connecting line is arranged between the floating plate and the tank roof.

[0017] Both ends of the equipotential connection line are crimped with wire lugs, one end is fixed on the floating plate, and the other end passes through the side wall of the tank roof manhole and is fixed on the outer wall of the manhole.

[0018] The equipotential connection line adopts a metal twisted wire with a diameter not less than 5mm.

[0019] Both ends of the equipotential connection line are fixed with bolts not smaller than M10 and anti-loosening washers.

[0020] There should be a certain distance between the opening on the side wall of the manhole and the fixing point, ensuring that the maximum distance between the equipotential connection line and the manhole...

Abstract

The invention provides an equipotential connection method of an internal floating roof storage tank floating disk and the tank top. An internal floating disk and a tank top manhole are comprised. An equipotential connection wire is arranged between the floating disk and the tank top. A test loop is established. The equipotential connection wire can be conveniently and accurately detected. An internal floating roof tank can safely run.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to an equipotential connection method between a floating plate and a tank roof of an inner floating roof storage tank. Background technique [0002] With the development of the world economy, the consumption of light oil products such as gasoline and diesel is increasing rapidly, and the reserves of all countries are constantly increasing. Internal floating roof storage tanks are an important way to store light oil. The oil tank is easy to generate static electricity when entering and leaving the oil. If it cannot be released in time, it is very easy to ignite the fuel due to static electricity discharge, resulting in a fire accident in the oil tank. Whether the equipotential bonding line of the storage tank is good or not has become a key factor for electrostatic discharge. However, in the actual operation of the storage tank, the equipotential connection line is da...
