HYDROCYCLONE-FILTERING DEVICE FOR WATER CLEANING Russian patent published in 2007 - IPC B01D36/00 C02F9/02 

FIELD: cleaning water.

SUBSTANCE: device comprises a set of pressure super-velocity filter arranged symmetrically, pipeline with valve gate for supplying the initial water axially aligned along the vertical of the pressure cylindrical chamber for distributing initial water among the filters, pressure cylindrical chamber for distributing the initial water over the hydrocyclones, pressure cylindrical chamber for collecting the cleaned water, pressure cylindrical chamber provided with horizontal baffle that separates the chamber into the bottom section for collecting contaminated washing water and top section for collecting slime water from the bottom drain branch pipes of the hydrocyclones. The bottom section is provided with the pipeline with valve gate for discharging the contaminated washing water, and the top section is provided with a special pipeline with valve gate and controllable hydraulic gate for control of the pressure in the top section and discharging the slime water. The branch pipe of the pipeline with the valve gate is connected with the horizontal baffle. The pipeline with the valve gate and controllable hydraulic gate allows the slime concentration to be constant when the admixture concentration in the initial water varies. The device is provided a set of hydrocyclones interposed between the pressure cylindrical chambers. The set of the hydrocyclones is made of axisymmetric pressure hydrocyclones and pressure cylindrical chamber for distributing initial water among the hydrocyclone, tangential outlet branch pipes for supplying initial water to hydrocyclones, top drain branch pipes of hydrocyclones connected from bellow with the bottom of the cylindrical chamber for distributing the initial water over the filters. The pressure cylindrical chamber for distributing initial water over filters is connected with the pipeline for supplying initial water to the device through the pipeline provided with the valve gate.

EFFECT: enhanced efficiency and reduced sizes.
