Ceramic raschig ring packing is bubbled through the liquid layer and brought a large amount of liquid out of the top of the tower, and the operation of the tower was extremely unstable or even completely destroyed, which was called liquid flooding.The turning point at which liquid flooding begins to occur is the flooding point, and the corresponding empty tower gas velocity is called liquid flooding gas velocity or flooding point gas velocity.The main factors affecting the flooding point gas velocity are the characteristics of the filler (specific surface, void ratio, geometric shape, etc.), the physical properties of the fluid (density, viscosity, etc.), and the flow rate of the gas-liquid two phases.The flooding gas velocity is the upper limit of the normal operating gas velocity of the packed column, and the actual operating gas velocity is usually 50% ~ 85% of the flooding gas velocity.
Ceramic Raschig Ring with excellent acid resistance and heat resistance.They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide.Ceramic Intalox Saddle can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
