ABSTRACT:
The invention is an in-line mixer without moving parts, with a generally conical shear head pointed in the upstream direction within a pipe, and centered near the downstream side of an annular seating ring fastened to the inside surface of the pipe. In the upstream, slanted face, or high pressure side of the shear head, there is a series of generally circular ports bored through the shear head. The slanted face of the conical shear head extends through the center of the seating ring in the upstream direction, and is adjusted to be located very close to the downstream side of the seating ring. At the downstream end of the slanted face of the shear head is a first sharp, approximately 90 degree edge leading away from the inside surface of the pipe in the downstream direction, which first edge is adjusted to be located very close to the inside surface of the pipe. This way, intense shearing forces are created at the edge of the downstream side of the annular seating ring near the inlets of the ports, and at the edge of the downstream end of the slanted face of the shear head near the inside surface of the pipe. Also, intense mixing forces are created at the downstream side of the annular seating ring near the inside surface of the pipe, and at the back of the shear head.
