Description

The device is designed to enrich water with oxygen, especially for enriching water in fish pools.

There is a known device for enriching water with oxygen - an ejector [1]. The principle of operation of the ejector is based on the use of the kinetic energy of water flow directed into a tube of smaller diameter. When changing the section of the tube, the speed of the water increases and the pressure decreases. As a result, a vacuum is formed inside the ejector, which serves as a driving force that ensures air suction through the side suction pipe of the ejector and their mixing with the main water flow.

This device has a low rate of water saturation with oxygen, since it is saturated with air, which, in turn, consists of 78% nitrogen and only 20% of oxygen, therefore, in addition to oxygen, water will also be enriched with nitrogen to a greater extent.

Known device for saturating water with oxygen - an aerator with a vertical flow generator [2]. The aerator is a cone with an open bottom; the motor and float are located in the upper part of the device. The principle of operation is that in the upper part of the cone the speed of water exceeds the rate of rise of bubbles, and at the bottom - the speed of water is slightly lower than the rate of rise of bubbles. Thus, the maximum duration of contact of water with gas is achieved, due to which oxygen enrichment occurs.

Due to operation at atmospheric pressure, this device has a low rate of saturation of water with oxygen, and also increases oxygen consumption, since part of the undissolved oxygen escapes into the atmosphere.

Known device, taken as a prototype, which is a cone-shaped container, in the upper part of which there are an opening for water supply and an oxygen supply pipe, and in the lower part an opening for an outlet of oxygen-enriched water [3]. The principle of operation is as follows: a liquid is supplied through the inlet of the cone, which is enriched with oxygen, passing through gaseous oxygen, which is supplied through the oxygen supply tube. Due to the high speed of water flow through the water supply hole in the upper part of the cone, oxygen does not have time to rise up. By increasing the diameter of the cone, the speed of the water decreases, due to which a zone of intense mixing of oxygen with water is formed. In this case, oxygen bubbles have time to rise to the top of the cone and are not carried out through the outlet of oxygen-enriched water.

The disadvantage of this device is the small area and time of contact of water with oxygen.

The technical result of the proposed device consists in increasing the rate of water enrichment with oxygen by increasing the area and time of contact of water with oxygen.

The technical result is achieved in that a cone-shaped choke is installed inside the cone-shaped container, and below it there are oxygen supply pipes.

FIG. 1 shows a general view of a device for enriching water with oxygen.

FIG. 2 shows a section A-A (see Fig. 1).

The device consists of a cone-shaped container 1, a water supply hole 2, an oxygen supply pipe for primary enrichment 3, oxygen supply pipes for additional oxygen enrichment 4, a cone-shaped choke 5 and an outlet for oxygen-enriched water 6.

The device for enriching water with oxygen works as follows. Water is supplied through the water supply holes 2. Oxygen is supplied to the water flow through the oxygen supply pipe for primary enrichment 3. The water flow rate does not allow oxygen bubbles to leave the cone-shaped container 1. By increasing the diameter of the cone-shaped container 1, the water flow rate decreases, which ensures the rise of oxygen bubbles to the zone of high water flow rate ... Due to this, a zone of intensive mixing of oxygen with water is formed, due to which the primary enrichment of water with oxygen is carried out. After the primary enrichment of the water 'with oxygen, the water passing through the gap formed between the windy surface of the cone-shaped container 1 and the cone-shaped choke 5 is accelerated to a flow rate approximately equal to the flow rate passing through the water supply holes 2. Below the cone-shaped choke 5 there are branch pipes for secondary oxygen enrichment 4, through which oxygen is supplied to the water stream. Due to this, an additional zone of intensive mixing of oxygen with water is formed, due to which the water is re-enriched with oxygen. After the water leaves the lower part of the cone-shaped container 1, the water flow rate decreases, which ensures the rise of oxygen bubbles and does not carry them out through the outlet openings of oxygen-enriched water 6.

Due to the additional zone of intensive mixing of oxygen with water, the area and time of contact of water with oxygen increases and the rate of saturation of water with oxygen increases.
