VOLKOV CAVITATIONAL AERATOR

Abstract

Proposed is a device for aerating a liquid. The device includes a housing having a liquid inlet channel, an air inlet channel and an outlet channel for a mixture of liquid and air. Mounted in the housing is a conical nozzle containing a swirler for feeding in liquid under pressure, the swirler having helical grooves on its outer surface. Mounted in the region where a conical jet of liquid exits an opening in the conical portion of the nozzle is a baffle with which the flow of liquid collides, resulting in cavitation, wherein air enters into the inner region of the jet of liquid via a channel in the baffle and through an opening in the baffle.

Claims

1. A device for aeration of a liquid comprising: a housing with a liquid supply channel, an air supply channel and a channel for removing a mixture of liquid and air, wherein the liquid is supplied under pressure to a hollow-cone nozzle installed in the housing with a swirler located inside it and having screw-cut channels on an outer surface, wherein in an exit zone of the conical liquid flow plume from the opening of the conical part of the nozzle, a baffle is installed, upon impact of which the liquid flow occurs, cavitation occurs, air enters the inner zone of the liquid flow plume through the channel in the baffle and through the hole in it.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0009] The essence of the proposed invention is explained by the attached drawing.

[0010] FIG. 1 shows a schematic diagram of the proposed device. The aerator comprising a housing 1, with a nozzle 2, which is essentially a hollow cone with a swirler 3, with a screw thread of flow passages 4 on its outer surface, the baffer 5, located opposite the opening of the tapered part of the nozzle, with a channel 6 for air suction, a water supply channel 7 and a water-air mixture outlet channel 8.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The device works as follows. Water or other liquid medium from a source (borehole or city water supply) is supplied under pressure to the aerator 1 to the nozzle and, while traveling through the channels of the swirler, acquires a kinematic helical movement. When exiting through the hole of the tapered part of the nozzle, it forms a hollow conical jet of water with a spiral movement of water particles relative to the aerator body. In the inner zone of the said water jet 9, due to the cavitation effect generated in the zone of water jets impact against the baffle, a zone of reduced pressure is formed. The air is sucked into it through channel 6 in the baffle, which, reaching the inner zone of the hollow conical jet of water, is captured by water and is vigorously mixed with it, which several-fold enhances the effect of, for instance, oxygen saturation of water. Then the gas-air mixture is directed through channel 8 to the separator for water degassing.
