Description

The proposed utility model can be used to increase the oxygen content in the pond.

Known oxygenator [1], consisting of an elongated cylindrical body, an oxygen gas supply pipe, a gas tap and a water outlet pipe, characterized in that the water supply pipe is connected to a “water lock” system, the elongated cylindrical body with its lower part is hermetically fixed inside a cylindrical base containing at least one water outlet pipe, while on the bottom of the elongated body along the entire circumference, slots are made for water to pass, and between the walls of the elongated body and the base made a system of vertical barriers, allowing the fluid to move in different directions.

This oxygenator cannot be placed directly in the pond and does not provide an intensification of the dissolution of oxygen in water.

A device is known for saturating a pond’s water with oxygen [2], it consists of a pontoon on which a vertically located pipe is fixed. The pontoon is flexibly connected to the weights placed at the bottom of the reservoir. In the inner cavity of the pipe, a shaft is made along its axis, at the lower end of which a pump wheel is fixed. The upper part of the pipe, located above the surface of the water, is made with holes evenly spaced around the perimeter of the pipe and equipped with spray nozzles at an angle to the vertical axis of the pipe. At the upper end of the shaft, emerging from the end of the upper part of the pipe, a wind wheel is made with the rotation of the blades in the horizontal plane. Spray nozzles are placed under the blades of the wind wheel and are directed towards the wind wheel at an angle. The angle between the nozzles and the vertical axis of the pipe is determined by calculation or experimentally. Perhaps the device nozzles in several rows at different angles or in the same row through one at different angles.

This device provides mixing and spraying of water at atmospheric pressure, which is ineffective. Also, the design of the device involves the dissolution in water of oxygen contained in the atmosphere at a concentration of about 20%.

A device for oxygenation of the reservoir LOXY [3], which provides a sufficient supply of oxygen from 16 to 25 l / min The device consists of a housing having openings for water inlet and outlet, a fitting for connecting an oxygen supply, an electric motor and a rotor-stirrer inside the housing. The device works as follows: the device is immersed in water, water fills part of the internal volume of the body with a mixing device. Air from the cavity exits through the air discharge pipe in the housing. An electric motor is turned on, which rotates the mixing device. Through the fitting, oxygen is supplied to the body cavity. In the process of actively mixing water with a mixing device, oxygen dissolves in water.

This device provides mixing of oxygen with water at atmospheric pressure, which is not effective. Since oxygen is supplied under pressure, undissolved oxygen enters the atmosphere through an opening in the housing and is irretrievably lost.

The closest known analogues is the reservoir oxygenation device [4]. The device consists of a hollow body having openings for water inlet and outlet of a vertical channel on the right side of the body, a compressor, and a perforated pipeline for supplying air to the body cavity. The device works as follows: the device is installed on the bottom of the reservoir, water fills part of the internal volume of the body. In the part of the hollow body filled with air, a pressure is created that exceeds atmospheric pressure. The compressor that feeds

atmospheric air through the pipeline. Further, air enters into the housing through perforation in the pipeline. In the process of raising air bubbles to the part of the body cavity filled with air, air oxygen dissolves in water. During operation, the air volume in the housing increases. The water level in the housing drops below the upper edge of the outlet and part of the air from the cavity enters the vertical channel and rises up to the surface of the reservoir. An airlift effect takes place in the channel and water from the housing is also sucked up along the vertical channel, being replaced by new water through the inlet in the opposite part of the housing.

This device provides contact of atmospheric air with water, which is not effective for dissolving oxygen, since the concentration of oxygen in atmospheric air is about 20%.

The technical result achieved by the proposed device oxygenation of the reservoir, is to increase the intensity of the process of dissolution of oxygen in water.

The technical result is achieved by the fact that the oxygenation device of the reservoir, including a housing containing a baffle that divides it inside into two parts, a supply pipe of an oxygen-air mixture or oxygen and a sprayer, further comprises a fitting for connecting an oxygen supply line, the housing is made hollow, the partition is made with the possibility overflowing water through it, while the hollow body is equipped with a pipe for intake of an oxygen-air mixture or oxygen from the body and a pipe for supplying an oxygen-air mixture or oxygen in a spray b, located in one of the housing parts.

In FIG. 1 shows a diagram of a pond oxygenation device.

In FIG. 2 shows the position of the oxygenation device in a pond.

The oxygenation device of the reservoir consists of a housing 1, inside of which a partition 2 and a spray gun are mounted 6. A pipe for collecting the oxygen-air mixture or oxygen 3 from the housing 1 and a supply pipe 4 of the oxygen-air mixture or oxygen to the spray gun 6 are installed on the housing. The device also includes the connection pipe for the oxygen supply line 5. Moreover, the connection pipe for the oxygen supply line can be located both on the housing 1 and on the intake pipe of the oxygen-air mixture or oxygen 3 and the supply pipe of the oxygen-air mixture or oxygen 4 (see Fig. 1).

Device oxygenation of the reservoir works as follows. The oxygenation device of the reservoir is installed at the bottom of the reservoir by the housing 1, or suspended in the water column, or not completely immersed under the surface of the water. Water entering the housing forms a gas cavity inside the housing. To ensure the water level inside the device’s housing flush with the partition, excess gas is removed from the gas cavity inside the housing 1, for example, through the fitting of the oxygen supply line 5, or in any other way. Since the gas cavity inside the housing 1 has no communication with the atmosphere, the gas pressure in the cavity will be higher than atmospheric and will depend on the immersion depth of the device. Further, oxygen is supplied under pressure through the connection of the oxygen supply line 5. The pressure of oxygen supplied through the atomizer 6 is selected so as to displace water from the housing 1 to the level depicted in FIG. 2. Upon reaching this level, the oxygen supply stops. The mass of the device is selected in such a way that provides the device with negative buoyancy. Next, the pumping of the oxygen-air mixture from the gas cavity inside the housing 1 through the intake pipe of the oxygen-air mixture or oxygen 3 into the supply pipe of the oxygen-air mixture or oxygen 4, from where the oxygen-air mixture is supplied to the atomizer 6. Oxygen-air mixture passing through the atomizer 6, it breaks into micro bubbles and enters the water inside one of the parts of the housing 1. Thereby, the contact area of gas-water increases and the active dissolution of the oxygen-air mixture begins during the ascent and micro bubbles to the gas cavity inside the housing 1. During the lifting of the micro bubbles inside one of the parts of the housing 1, a gas-water mixture is formed whose density is lower than the density of water at the depth of the device. Because of this, the column of the gas-water mixture rises above the partition 2 and the water overflows into the adjacent part of the housing 1. Then, the water flows by gravity from the housing 1, and a new portion of the water comes from the other side (see Fig. 2). Further, oxygen and air, which did not have time to dissolve, are again collected in the gas cavity of housing 1. Since part of the oxygen and air has dissolved, the pressure in the gas cavity has decreased and oxygen supply is resumed through the connection of the oxygen supply line 5. Pressure increases - oxygen supply stops . The process is then repeated. In this case, the air concentration gradually drops to 0 and pure oxygen is supplied to the atomizer 6.
