Where should the feed inlet of the storage tank be located?
Thread Content
The feed inlets that I saw on site were all located at the upper part or top of the storage tank. Yet P147 states that \"the feed inlets of the storage tank should be placed at the lower part of the tank wall or at the bottom of the tank surface. If they are to be located at the upper part, they should extend 200 mm down to the bottom of the tank, and measures should be taken to prevent siphoning.\" What is the purpose of such a setup? Is it to prevent static electricity from accumulating due to the free fall of the liquid? Please discuss this
Storage tanks are all electrically grounded to prevent static electricity from building up to dangerous levels.
Excuse me, LZ, what kind of material is stored in that tank of yours?
When entering from the top, it extends to the bottom of the tank to prevent large fluctuations in the liquid level. Additionally, if there is air above the liquid surface, the heavier oil at higher temperature enters the tank from above to avoid direct contact with the air and thus spontaneous ignition.
1. Currently, radar level gauges are generally used in storage tanks; feeding is done directly from the top of the tank, and fluctuations in the liquid level lead to inaccurate readings from the level gauge. 2. For materials that are corrosive, this can accelerate the corrosion of the tank walls. 3. The static electricity generated by flammable and explosive materials can easily cause fires or explosions

It is mainly aimed at flammable and explosive substances, to prevent liquids from entering directly through the top of the tank and falling into the gas phase space, where the resulting impact force can be excessive, leading to volatilization losses as well as the generation of frictional static electricity.
Feeding materials from the bottom ensures thorough mixing and homogenization.
It has the following functions: 1. It prevents liquids from evaporating easily, which could otherwise cause pressure fluctuations in the storage tank; 2. As the liquid enters from the bottom, it prevents violent movement of the liquid due to temperature differences between the top and bottom; 3. It helps to prevent static electricity; 4.
9# wang*nhua77020 The key question is: where is your 4?
Thank you to everyone upstairs; it seems to be specifically related to flammable and explosive liquids indeed~
