A mixing and blending system in which pulsed air or gas bubbles (45, 46, 47) of predetermined variable size and frequency are injected into a tank (10, 60, 80) containing materials to be agitated or stirred for mixing and blending. The air introduced at the bottom of the tank through an air inlet opening (24, 25). There may be more than one air inlet and the inlets may be provided with accumulator plates (42) depending upon diameter and hight of the tank in which the mixing and blending is taking place. The inlets are located so as to create circular toroidal flow (48, 50, 52, 54) of fluid in a generally vertical plane. The accumulator plate has the purpose of assisting the formation of essentially a single bubble (46) from the compressed air charge made to the air inlet and increasing the time required for the bubble to rise through the liquid by causing it to be formed more quickly and closer to the bottom of the tank. Hence, the accumulator plate (42) is utilized in low viscosity liquids such as water. |
