Tank Mixing
In many applications, it is necessary to keep the contents of a tank mixed or stirred. Conventional mixing in a tank requires mechanical mixing components, such as a fan powered by a large motor. However, many applications where immiscible liquids need to be mixed or solids need to remain in suspension can be performed with just a pump and submerged spray heads. This significantly reduces system complexity, capital costs, and maintenance requirements.
BETE nozzles for tank mixing
The BETE TurboMix liquid mixers are fully submerged in the liquid in the tank and operate on the simple principle that when velocity increases, pressure decreases. They are designed to capture the velocity of the liquid being pumped through the nozzle and convert it into a low-pressure zone, allowing the surrounding liquid in the tank to flow into the nozzle. In this way, the pumped liquid is effectively mixed with the tank contents, and the amount of liquid coming out of the nozzle is three to five times the amount of pumped liquid. This multiplier effect results in greater mixing efficiency while using a smaller pump capacity.
Different options for tank mixing
Even after liquids have been combined, mixing nozzles can keep the combined liquid in motion. For example, if the mixture contains lighter or heavier solids than the liquid, stirring prevents them from floating or sinking. The same applies to liquids with two different densities or mixtures of oil- and water-based compounds. Moreover, uniform liquids can stagnate, promoting bacterial growth and causing temperature-based layering. By stirring, the solids remain evenly suspended while also preventing bacterial growth.
Recirculation system
The most common setup consists of a recirculation system. The suction side of the pump is connected to the tank and draws the liquid through this line. The pressure side of the pump is led through pipes to the inlet of the nozzle. The liquid is sucked from the tank, passed through the pump, and fed to the nozzle. More liquid is entrained and expelled through the nozzle. The emitted stream disperses throughout the tank and keeps the liquid in motion. With the nozzles properly positioned, mixing occurs without moving components in the tank. Other setups than recirculation systems are also widely used. Fresh feed is supplied to the inlet of the nozzle instead of being recycled from the tank. Mixing of the fresh feed occurs immediately with the tank contents and continues to mix as the outlet jet propagates downstream.
