An anti-sloshing liquid storage system with a self-cleaning porous medium layer

Abstract

The invention discloses an anti-shake liquid storage system containing a self-cleaning porous medium layer. By setting the porous medium layer in the liquid storage tank, the outer skeleton of the porous medium layer is bent to form a cylindrical steel cage structure; the porous medium layer The interior is filled with hollow aluminum balls and other materials to achieve the anti-shake effect; a tank washing device is installed between the inner wall of the liquid storage tank and the porous medium layer, and the tank washing device includes a sequentially connected air intake mechanism and several blowing mechanisms; the gas passes through the inlet The air mechanism and the blowing mechanism blow to the porous medium layer, so that the solid impurities in the pores of the porous medium layer are blown off and deposited in the temporary storage area at the bottom of the liquid storage tank, and finally discharged through the overflow pipe. This system effectively realizes the slosh reduction effect when the internal liquid storage is sloshing, and can remove impurities in the gaps of the porous medium layer, and realizes the automatic and safe operation of the whole system by using the monitoring computer.

Description

technical field [0001] The invention belongs to the field of anti-sway liquid storage systems, in particular to an anti-sway liquid storage system containing a self-cleaning porous medium layer. Background technique [0002] Vertical cylindrical storage tank is a device for efficiently storing important liquefied energy resources such as petroleum liquefied natural gas. However, frequent natural disasters, such as earthquakes and tsunamis, pose a great threat to the storage security of such important resources. The strong external excitation causes the overall displacement of the liquid storage tank, resulting in the sloshing phenomenon of the dynamic response of the internal liquid. The strong internal sloshing will generate a huge impact load on the inner wall of the liquid storage tank, and even lead to the destruction of the entire liquid storage tank structure and the leakage of liquefied fuel. Therefore, the large liquid storage tank should have the function of reduc...

AI Technical Summary

Problems solved by technology

However, there are still many places worthy of optimization and problems that should be solved in practical applications. For example, the porous medium is arranged in the middle of the liquid storage tank, which has a limited effect on reducing the wave impact force on the wall of the liquid storage tank.

In addition, since most liquid fuels, such as crude oil, carry a lot of solid impurities, large particles of solid impurities will inevitably remain on the surface or inside of the porous medium layer in practical applications, causing the internal lumen of the porous medium to blockage, resulting in a significant decrease in its vibration reduction effect
