Abstract

Apparatus to a technique for aerating waste water at aeration stations and water in fish ponds. The purpose of the invention is to increase the efficiency of water saturation with oxygen in the air. The installation includes a tank, a support, a working pump, pipelines, an aerator that includes a housing, a suction nozzle, a mixing chamber, and a nozzle. Air inlet to the nozzle is provided due to the dilution that occurs at the cutoff when water flows from the nozzle at a speed of 25 - 40 m / s. The suction nozzle and the mixing chamber are made of two parts connected by corrugated elements of elastic material. This embodiment allows the movable parts of the nozzle and the chamber to oscillate, a turbulent regime is created, which increases the efficiency of water saturation with oxygen by oxygen. 2 Il.

Description

This invention relates to a technique for measuring the water content of fish ponds with atmospheric oxygen, as well as for aeration of wastewater.

The purpose of the invention is to intensify the process of saturating water with oxygen in the air and increasing the volume of saturable water by providing a turbulent regime in the mixing chamber.

Figure 1 shows a plant for aerating water, a view; figure 2 - aerator, longitudinal section.

The plant for aeration of water contains a tank 1 mounted on a frame 2, a pump 3 with suction and pressure pipes 4 and 5 and an aerator fixed to the tank 1 by means of a rigid connection 6.

The aerator consists of a housing 7 with a pipe 8 for supplying water, a suction pipe and a mixing chamber arranged coaxially with each other.

The suction nozzle consists of fixed and movable parts 9 and O, connected by a corrugated element 11 made of an elastic material, for example rubber. The input end of the fixed part 9 of the suction nozzle is located outside the housing 7, and the output end of the movable part 10 of the suction nozzle, the nozzle is located in the displacement chamber so that an annular gap 12 is formed between them.

The displacement chamber consists of fixed and movable parts 13 and 14 connected by a corrugated element 15 made of an elastic material. The movable part 14 of the displaced chamber is provided with a conical nozzle 16.

Installation for aeration of water works as follows.

The tank 1 is filled with water so that the water level is 200-250 mm below the end of the conical nozzle 16. The pump 3 is turned on. The water from tank 1 through suction pipe 4, pump 3, pressure pipe 5 and pipe 8 for water supply enters the body cavity 7 ejector. Since the movement of water in the body cavity has a turbulent character and the suction nozzle consists of a stationary 9 and a movable 10 parts connected by an elastic corrugated element 11, then when water passes through the annular slot 12, the movable part 10 of the suction nozzle makes random in different directions hesitation. At the same time, the speed and dimensions of the annular flow passing through the annular gap 12 are constantly changing. The passage through the annular slot 12, the flow of water is in contact with the air in the displacement chamber, directly in front of the movable part 10 of the suction nozzle. Moreover, since the movable part 10 of the suction nozzle makes random fluctuations, the flows of water and air are actively mixed in the mixing chamber to form a flow of water-air mixture. Into the place of air entrained by the flow of water, air from the atmosphere flows through the suction nozzle. Through the conical nozzle 16, the stream of water-air mixture is emitted outside into the atmosphere, additionally trapping air from the atmosphere, and entering the aerated water, which is filled with oxygen. Moreover, since the mixing chamber consists of two parts connected between one another and an elastic corrugated element 15, and the flow of the water-air mixture in the mixing chamber has a turbulent

character, the moving part 14 of the mixing chamber with the conical nozzle 16 makes random oscillatory movements in different directions. As a result, the volume of water saturated with air oxygen will increase significantly.

The fabrication of a suction nozzle from two parts interconnected by a corrugated element made of elastic material enables the movable part of the suction nozzle to be randomly oscillated in different directions, which leads to active mixing of water and air flows, which provides fine dispersion of atmospheric air.

in water.

The manufacture of a mixing chamber of two parts, interconnected by an elastic corrugated element, allows the movable part of the mixing chamber and the water jet to carry out irregular vibrations in different directions, which significantly increases the volume of water with oxygen.
