Static mixer manifold

A manifold for the mixing of solid and liquid slurry components comprising

• a low pressure pump for pumping slurry components to an inflow port fluidly connected to the manifold,
• a capped inner cylindrical chamber into which the inflow port fluidly delivers unmixed solid and liquid slurry components, which capped inner cylindrical chamber extends the length of the manifold and which cylindrical chamber is defined within a plurality of durable walls of an otherwise generally closed cylindrical shape for containing the flow of slurry components in the cylindrical chamber,
• a plurality of mixing ports disposed in the durable walls defining the cylindrical chamber and permitting the directed flow of slurry components at a predetermined angle into the bottom interior wall of a generally closed rectangular solid chamber exterior to the durable walls defining the cylindrical chamber, which rectangular chamber is defined within a plurality of durable walls of a generally rectangular solid shape and which further define the body of the manifold,
• in which the longitudinal axis of the cylindrical chamber is disposed parallel to and vertically below the longitudinal axis of the rectangular chamber,
• and in which a plurality of exit ports are disposed within a single wall of the plurality of walls of rectangular solid shape defining the rectangular chamber.

A method of mixing slurry in which slum components are pumped under pressure into a static mixing chamber defined by a generally closed inner cylindrical surface extending the entire length of a generally closed outer rectangular surface in which directed flow out of an inner cylindrical tube impinges angularly on the bottom interior surface of an outer rectangular tube, and comprising the steps of:

• pumping slurry components into a cylindrical tube positioned wholly within an outer rectangular tube in which the longitudinal axis of the cylindrical tube is parallel to and below the longitudinal axis of the rectangular tube
• directing outflow from the cylindrical tube at predetermined angles through a plurality of mixing ports disposed on the walls of the cylindrical tube positioning the cylindrical tube relative to the outer rectangular tube such that the slurry components impinge the inner walls of the outer rectangular tube at least one angle substantially away from the perpendicular
• in which the geometry of the outer rectangular tube relative to the cylindrical tube causes instabilities to form in the flow of slurry components between the cylindrical tube and outer rectangular tube
• in which pumping pressure and flow rate of the slurry components results in turbulence in the flow of slurry components, resulting in static mixing.
