A tank mixing eductor is a type of eductor that is used to mix liquids within a tank. It works by creating a low-pressure area that draws in and mixes the contents of the tank.
Here’s how a tank mixing eductor works:
-
The fluid that provides the energy, called the “prime fluid,” enters the eductor through an inlet.
-
The prime fluid then flows through a converging section, which narrows the cross-sectional area of the flow. This causes the velocity of the fluid to increase and the pressure to decrease.
-
The high-velocity, low-pressure prime fluid then enters a constricted throat, where its velocity is further increased.
-
As the prime fluid exits the throat, it enters a diverging section, where its velocity decreases and its pressure increases. This creates a region of low pressure in the eductor, which draws in the contents of the tank.
-
The fluid from the tank is drawn into the low-pressure region and mixed with the prime fluid in the diverging section. The mixture is then discharged from the eductor through an outlet.
-
The flow of the mixture back into the tank creates turbulence and promotes mixing of the tank contents. This can help to homogenize the contents of the tank, distribute additives evenly, or improve heat transfer.
The design of a tank mixing eductor can be optimized to meet specific mixing requirements, such as ensuring a certain level of turbulence or achieving a certain flow rate. The effectiveness of the eductor will depend on factors such as the flow rate and pressure of the prime fluid, the design of the converging and diverging sections, and the properties of the liquids being mixed.
