DEVICE FOR FLOTATION PURIFICATION OF WATER Russian patent published in 2005 - IPC

FIELD: flotation purification of water.

SUBSTANCE: the invention is pertinent to the field of devices for purification of water of industrial and household sewage and is intended for removal of finely dispersed hydrophilic impurities, which electrokinetic potential exceeds 40 mV, proteins, fats, petroleum, surface-active agents and other analogous substances. The device contains: a rectangular shape body in the plan with paired parallel partitions and placed between them one over another perforated pipelines for feeding of a water-air mixture; a unit of withdrawal of purified water with a collecting chamber; a mechanism for removal of a froth with and a froth collector;, a device for saturation of the initial water with the air bubbles, that consists of a pump, an ejector and a pneudraulic dispersant. The perforated pipelines are linked with the pneudraulic dispersant by a pipeline with a check valve and have at least two rows of apertures, which in the lower perforated pipeline are facing up, and in the upper pipeline - facing downwards to provide a counter intersecting traffic of jets of the water-air mixture. The technical result is an increase of efficiency of water purification, a decrease of dimensions of the device and power consumption.

EFFECT: the invention ensures increased efficiency of water purification, decreased power consumption and dimensions of the device.
