Description

 The invention relates to environmental protection and is used, in particular, for aeration of river water in winter.

A device for increasing the oxygen concentration in running water, consisting of a pipe of complex configuration containing a neck and a diffuser, a flexible hose, a float and an anchor [1]
The disadvantages of this device are insecurity from clogging and flooding, lack of efficiency of the aeration unit, as well as the inability to use the device in the winter.

Closest to the invention is the device "Strela-4", consisting of support frames for pontoons, electric motors, aeration nozzles, pipes, air intake [2]
The disadvantage of this device is the design complexity.

 The purpose of the invention is to simplify the design of the aerator.

 The goal is achieved by the fact that the pipeline is laid on ice, across the river, and the aerator is made in the form of a disk with a central hole, to which an air pipe is connected, which connects to the pipeline with its second end, a mesh atomizer is attached around the disk perimeter, in volume, the prevailing volume cavitation cavity. The pipeline is connected to air ionization units.

 Distinctive features of the proposed technical solution is that the device contains mounted on ice, across the river and at certain intervals, aerators placed on the supports, each aerator is made in the form of an air tube with a disk fixed to it with a central hole and a mesh spray, and the air tubes are interconnected by a pipeline placed on the ice of the river, across its course, and are made with air ionization units connected to the atmosphere.

 The present invention meets the criterion of "novelty", as it is not known from the prior art.

 In addition, the technical solution meets the criterion of "inventive step", as specialists obviously do not follow from the prior art, and is also industrially applicable.

 Figure 1 shows the device; figure 2 section aa in figure 1.

 The device comprises a pipeline 1, laid along the river’s ice across its course, connected to air ionization blocks 2, while aerators 3 are attached to the pipeline at certain intervals, to which ionized air is supplied from the pipeline through air tubes 4, disk 5, preventing the movement of water, forms a zone of reduced pressure. On the reverse side of the disk along its perimeter, a mesh atomizer 6 is attached, with a volume larger than the volume of the cavitation cavity. The reduced pressure zone contributes to the suction of air through the Central hole 7, the stability of the aerator is carried out due to the support-cross 8, the aerator is lowered to a depth through the hole 9, the pipeline is laid on ice 10.

 The device operates as follows.

 The pipeline 1 is laid on ice 10, across the river, and is connected to air ionization blocks 2, which are installed on both banks. Aerators 3 are connected to the pipeline 1 at certain intervals, the stability of which is ensured by supporting crosses 8, for installing aerators 3, holes 9 are hollowed out in ice, water freezing fixes the aerators 3, which fall to a depth greater than the depth of freezing water. The disk 5 of the aerator 3, preventing the movement of water, creates a zone of reduced pressure (cavitation cavity), which contributes to the suction of air through the central hole 7 of the disk 5, through the air tube 4 from the pipeline 1 and block 2 ionization of air. Air, passing through a mesh sprayer 6, is sprayed onto small bubbles, enters the water, neutralizes and aerates it. Before the ice drift, in spring, the device is dismantled.

 Technical and economic advantages of the proposed technical solution consist in simplifying the design of the aerator and in increasing the efficiency of aeration due to ionized air.
