Vortex diodes as effluent treatment devices

摘要

The present invention discloses device that can generate a strong vortex in the vortex chamber which significantly enhances rate of reactions and effectiveness of waste water treatment. The present invention disclose vortex diodes with or without inserts/stabilizers as continuous flow reactors to induce cavitation to generate radicals which reduces Chemical Oxygen Demand (COD), ammoniacal nitrogen and color of waste water effectively in effluent treatments.

主权项

1. A vortex diode for effluent treatment, wherein said vortex diode comprises:
i. a chamber provided with a single or multiple inlet as a tangential port, wherein a flow entering from the tangential port sets up a high resistance mode of operation; ii. a vortex stabilizer connected to the chamber, wherein said vortex stabilizer comprises a base with or without threads and an insert which lies within the chamber; the insert being symmetrical around axis of an axial port and being formed by revolving either a straight connecting line having slope or a curved line between a point on the axis of symmetry of the chamber and a point lying on the base opposite to the axial port; and iii. the axial port being provided in the chamber for discharging treated effluent water; wherein the vortex stabilizer has a diameter in a range of 10 to 40% of a diameter of the chamber and a height less than 15% of the diameter of the chamber.
