Vortex prevention device for absorption tower

The principle of the vortex prevention device in the absorption tower is to prevent vortices from forming at the outlet by changing the direction of the liquid flow or reducing its speed. Vortices are typically generated due to an increase in the velocity of the liquid at the outlet or in areas where the flow is narrow; such flow leads to a local negative pressure, which in turn creates vortices. If the height of the acid outlet is lower than the controlled liquid level in the circulating acid tank, a similar overflow effect often occurs due to this difference in liquid levels, keeping the bottom of the absorption tower filled with acid. However, if the flow rate is too high or the design of the acid outlet is inadequate, vortices can still form; this may lead to air being drawn into the acid, affecting the quality of the acid produced, or it may cause cavitation damage to equipment such as pumps. Therefore, the installation of vortex prevention devices helps to maintain normal operation within the absorption tower, even when the acid outlet is below the control level, thereby ensuring the quality of the acid and the safety of the equipment. .

As sulfuric acid gradually flows from the shell toward the nozzle, the flow velocity increases, and the movement of the fluid particles becomes more irregular, which easily generates a rotational force at the liquid surface, ultimately leading to the formation of vortices. Eddy currents can easily cause the pipes to be underfilled; pipes using Yangbao are prone to failure, and corrosion in such pipes intensifies. The vortex prevention device works by altering the irregular movement of the fluid, directing it in a predetermined direction and thus preventing the formation of vortices. Is the opening height lower than the control liquid level of the circulation tank? Is the pipe full? The pressure in the tower also needs to be taken into account; the tank is at atmospheric pressure. If there are fans in front of the towers, all three towers will be under positive pressure. During operation, the liquid level at the pipe outlets is lower than that in the circulation tank.

To recover acid, the absorption tower will be higher than the circulation tank. It can be understood in this way: take a mineral water bottle, cut an opening at the bottom and turn it upside down; you will see a large number of bubbles flowing out of the bottle opening. The flow rate of water is also unstable. By adding a vortex generator, the flow rate becomes stable, and the water flow does not fluctuate sharply, preventing gas from entering the circulation tank

The principle of vortex suppressors is to prevent or reduce the effects of vortices by changing the direction of fluid flow, thereby separating vortices and suppressing disturbances. The materials we produce include acid-resistant alloy steel vortex suppressors, 316L stainless steel vortex suppressors, 904L vortex suppressors, as well as drying and acid-returning sleeves made from various materials, along with vortex suppressors crafted from different materials.
