ABSTRACT:
Disclosed is a liquid mixer having a multiplicity of slotted orifice plates spaced apart along the flow path within a chamber. Liquid passes through and exits from the slots at a 30-60 degree angle to the exit face of the orifice plates, thereby inducing turbulence which causes good mixing. Preferably the slots are radially disposed in circular orifice plates fitted closely within a cylindrical chamber. The radial length L of the slots is preferably five times the slot width T, and the spacing S of the orifice plates is 4-8 times the width. Straight slots are simplest to make but curved slots are preferred. Radial slots in a circular disc are preferred but other orientations are useful. When used for dispersing small volumes of water into oil, water is injected transversely into the oil upstream of the orifice plates, to cause initial droplet formation; and, the oil-water fluid velocity through the slots is kept in the range of 80-1600 feet per second.
