HYDRAULIC MIXER FOR WATER TREATMENT BY COAGULANTS Russian patent published in 2014 - IPC B01F5/00 

FIELD: process engineering.

SUBSTANCE: invention relates to water treatment in whatever industry. Proposed mixer comprises tube length with cylinder to house turbulence promoter grate, reagent distributor composed of ring with distribution tubes and conical tank with perforated radial tubes. It differs from known designs in that said cylinder is mounted at tube length centre and features diameter larger that length proper. Said turbulence promoter grate is composed of vertical and horizontal rods. Said rods have coiled tape with alternate LH and RH coiling. Circular manifold connected with reagent feed pipe has holes made on its inner surface, their diameter increasing downward. Said manifold is connected with reagent accumulator by distribution tubes and has bush secured at its centre at the left side and orifice. Perforated cylinder with tank is arranged at the right and coaxially inside conical tank whereto radially connected are distribution tubes with ends plugs and openings.

EFFECT: improved coagulation.
