Abstract

This invention relates to the aeration of natural and waste waters. The aim of the invention is to increase the fine bubble aeration and increase the utilization rate of atmospheric oxygen. The jet aerator contains a cylindrical body with an air chamber and elements of a V-shaped form 3 installed between the flange of the liquid supply nozzle and the bottom of the aerator. Between the flange and the bottom of the aerator, tubes are installed communicating with the air chamber with nozzles oriented in the direction of fluid flow. The V-shaped elements 3 are placed with their vertices 9 on a circle 10 connecting the centers of sections of 11 tubes at an equal distance from the latter, with a conical divider mounted in the center of the bottom of the aerator. The side surfaces of the V-shaped elements 3 can be made wavy, and the distances between the V-shaped elements 3 at their peaks 9 are smaller than at the exit 13 from the jet aerator. The liquid under the working pressure on the pipe, streamlined cone divider, enters the space between the flange and the bottom of the aerator. A stream of water flows around the pipe with a nozzle that communicates with the air chamber. In this case, a vacuum is created in the space behind the nozzle, which causes spontaneous air leakage. The gas duct on the mixture, the passage between adjacent elements of a V-shaped form 3, is stirred and saturated with oxygen. The invention makes it possible to reduce the processing time of the liquid, as well as reduce the capital costs of the construction of the cleaning system. 2 hp ff, 2 ill.

Description

The invention relates to the aeration of natural and waste waters and can be used in agriculture for the aeration of manure drains.

The aim of the invention is to increase fine bubble aeration and increase the utilization rate of atmospheric oxygen.

FIG. 1 shows a cross section of a jet aerator; in fig. 2 is a section A-A in FIG. one.

The jet aerator comprises a cylindrical body 1 with an air chamber 2 and V-shaped elements 3 installed between the flange 4 of the liquid supply nozzle 5 and the bottom of the aerator 6. Between the flange 4 and the bottom of the aerator 6, tubes 7 with nozzles 8 are connected to the air chamber 2. oriented in the direction of fluid flow. The V-shaped elements 3 are placed with their vertices 9 on the circumference 10 connecting the centers of sections 11 of the tubes 7 at an equal distance from the latter, and in the center of the bottom of the aerator 6 a cone-shaped divider 12 is mounted. The side surfaces of the V-shaped element 3 can be made wavy, and the distance between the elements of a V-shaped 3 at their vertices 9 is less than at the exit 13 of the jet aeator.

Jet aerator works as follows.

The fluid under working pressure through the pipe 5, the flow around the cone divider 12, enters the space between the flange 4 and the bottom of the aerator 6. Water flows over the pipe 7 with the nozzle 8 connected to the air chamber 2. In the space behind the nozzle 8 a negative pressure is created that causes spontaneous air leakage. The gas duct on the mixture, the passage between adjacent elements of a V-shaped form 3, is stirred and saturated with oxygen. By making the side surfaces of the V-shaped elements 3 wavy

there occurs an alternation of the velocities and pressures of the gas-blend mixture, as a result of which the maximum displacement and saturation of the liquid with oxygen in the air is ensured. The invention allows to reduce the time

liquid processing, as well as reduce the capital costs of building a cleaning system.
