Description

The invention relates to the protection of the aquatic environment and can be used for aeration of water bodies.

A device for aeration of water is known [Patent RU No. 2471724. - Published on January 10, 2013 Bull. No. 1], containing the pontoon anchored in the reservoir, provided with a riser, lowered into the bottom layers of the reservoir, and a discharge pipe. The riser pipe has a receiving nozzle at the lower end for water inlet, and its side walls above the nozzle have perforation, which is connected to the atmosphere by an air pipe equipped with a confuser to meet the atmospheric wind. The upper end of the riser is also equipped with a confuser with the possibility of using rollers in the conductor to orient it towards the atmospheric wind, passing into the guide tube outside the outlet of the riser, which is connected to the discharge pipe by means of an annular water intake.

However, the known device has the disadvantage of low quality aeration of water, which, inter alia, depends on the wind pressure.

The technical result achieved by using the invention is to improve the quality of aeration of water.

The specified technical result is achieved by the fact that a mixing chamber equipped with a non-return valve is installed on the pontoon, which is made in the form of a hollow cylinder. Inside the mixing chamber, a swirl is coaxially mounted, made in the form of a hollow perforated conical screw installed by the side with a smaller outer diameter towards the check valve. A water pump is installed between the riser pipe and the mixing chamber. A compressor equipped with an outlet pipe is installed on the pontoon, and the compressor outlet pipe is connected to the internal cavity of the swirler.

In FIG. 1 shows a General view of the device.

The device for aeration of water includes a pontoon 1, equipped with a lifting pipe 2, lowered into the bottom layers of the reservoir, and a discharge pipe 3. On the pontoon 1 is equipped with a check valve 4 mixing chamber 5, made in the form of a hollow cylinder. Inside the mixing chamber 5, a swirl 6 is coaxially mounted, made in the form of a hollow perforated conical screw installed with a side with a smaller outer diameter towards the check valve 4. A water pump 7 is installed between the water pipe 2 and the mixing chamber 5. In addition, a compressor 8 is installed on the pontoon 1. equipped with an outlet pipe 9. The outlet pipe 9 of the compressor 8 is connected to the inner cavity of the swirler 6.

A device for aeration of water works as follows. Turn on the water pump 7 and compressor 8. At the same time, the pressure created by compressor 8 should not be less than the pressure provided by pump 7. Using pump 7, water from the bottom layers of the reservoir through the riser pipe 2 installed on the pontoon 1 through the check valve 4 enters the internal cavity of the mixing chamber 5, where then, moving along the outer surface of the swirler 6, it is involved in rotational motion, the speed of which gradually increases as water moves along the hollow perforated conical screw. In addition, when water moves in a turbulent flow, through the perforation of the swirler 6 from its internal cavity, air enters the water, pumped into the mixing chamber 5 by the compressor 8 through the outlet pipe 9. In this case, intensive mixing of water with air occurs. Aerated water enters the reservoir from the mixing chamber 5 through the discharge pipe 3.

The placement on the pontoon of the mixing chamber, made in the form of a hollow cylinder with a swirl coaxially mounted inside it, which is made in the form of a hollow perforated conical screw installed with the side with a smaller outer diameter towards the check valve, and also the connection of the compressor outlet pipe to the swirl swirl allows to ensure a high-quality course of the process of water saturation, which with the aid of a swirler moves translationally-rotationally in a turbulent state, by air, pressure from the compressor through the outlet pipe.

The presence of a water pump and compressor ensures the stability of the device, regardless of environmental parameters.
