Anti-oscillation liquid storage system comprising self-cleaning porous medium layer

Abstract

The invention discloses an anti-oscillation liquid storage system comprising a self-cleaning porous medium layer. Through arrangement of the porous medium layer in a liquid storage tank, an outer frame of the porous medium layer is bent through steel bars for forming a barrel-shaped reinforcement cage structure; the porous medium layer is internally filled with hollow aluminum balls and the like,so that the anti-oscillation effect is achieved; a tank washing device is arranged between the inner wall of the liquid storage tank and the porous medium layer, and comprises an air inlet mechanism and a plurality of air blowing mechanisms, and the air inlet mechanism and the air blowing mechanisms are connected in sequence; and air is blown to the porous medium layer through the air inlet mechanism and the air blowing mechanisms, so that solid impurities in gaps of the porous medium layer are blown down and deposited at a temporary storage of the bottom of the liquid storage tank, and finally discharged through an overflow discharge pipeline. According to the system, the oscillation reduction effect during oscillation of internal liquid is achieved effectively, and the impurities in thegaps of the porous medium layer can be removed; and the automatic safe operation of the whole system is achieved through a 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...

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
