The pipe is located vertically, the partitions are installed evenly along the entire length of the pipe, and the valve is located at the upper end of the pipe.

Description

The utility model relates to the field of water purification by ozonation. When using ozone for water treatment, devices for mixing ozone with water are of great importance. The quality of water treatment depends on the efficiency of ozone dissolution, which is ensured by the dispersion and contact time of the ozone-air mixture with the liquid.

A device for mixing ozone with water on the basis of the ejector (AS USSR No. 1483110, IPC ⁵ F 04 F 5/22, priority 31.03.87), in which the ejector consists of several stages to improve the quality of mixing. A disadvantage of the known device is the complexity of the design and the limited contact time of the ozone-air mixture with the liquid.

Also known is a mixing column consisting of three coaxial pipes and two ejectors (O. I. Shubravy, V. G. Aleshin "The use of ozone in water treatment in the pool": Collection No. 11. Workshop 05/20/99. "The use of ozone for water treatment in swimming pools and new methods for the synthesis of ozone in gas discharges ”). The disadvantage of this device is also the relative complexity due to the need to use two ejectors.

The closest in technical essence to the proposed device is a water treatment plant (RF patent No. 2225846, IPC ⁷ C 02 F 1/78, priority 13.09.2000), which contains in addition to the ejector device for the initial mixing of the ozone-air mixture with the cleaned contact chamber with partitions reducing the cross section of the chamber. The contact chamber contains an opening at one end for the entrance of treated water and an ozone-air mixture, at the other end there is an opening for the outlet of purified water and consists of four zones along the course of the mixture: the first zone A and the third zone B with labyrinth sections, the second zone B and an exit zone for a calm state of water, Zone A serves for intensive mixing of the ozone-air mixture with the addition of a coagulant with purified water, in zone B, impurities precipitate and, of course, an insoluble composition of ozone-air ear mixture, which leads to the formation in zone B of an air cushion. With the increase of this cushion, the entire installation may cease to function.

The safety valve for the release of air is located only in the outlet zone after the passage of water through zone B (in which the flocculant additionally enters).

Thus, the known device is not only complicated by the presence of two labyrinth sites for turbulization of the air-water mixture, but also does not have sufficient reliability due to the location of the exhaust valve.

The objective of the proposed utility model is to simplify effective mixing of water and increase the reliability of the device.

The problem is solved in that in the device for mixing ozone with water containing a pipe, at one end of which there is an opening for the entrance of the treated water and the ozone-air mixture, at the other end there is an opening for the outlet of purified water, a valve for air outlet, inside the pipe are installed partitions with a cut edge rotated 180 ° relative to each other, the pipe is vertical, partitions are installed evenly along the entire length of the pipe, and the valve is located at the upper end of the pipe.

Improving the reliability of the device is achieved due to the fact that the proposed device eliminates the area in which an air cushion may form. The ozone-air mixture is effectively mixed with water in the entire volume of the pipe, and the safety valve ensures the release of air when the specified pressure is reached.

The figure shows the design of a device for mixing ozone with water.

A device for mixing ozone with water contains a vertically mounted pipe 1, at one end of which there is an opening with a pipe 2 for the intake of treated water and an ozone-air mixture. At the other end of the pipe 2 there is an opening with a pipe 3, from which purified water flows. Inside the pipe 1, partitions 4 with a cut edge are installed, rotated 180 ° relative to each other. Moreover, the partitions 4 are installed evenly along the entire length of the pipe 1. The spacer elements 5 serve to fix the partitions. A safety valve 6 is installed on the upper end of the pipe.

The device operates as follows. Processed water and the ozone-air mixture enter the pipe 1 through the pipe 2. Passing through the pipe, the flow of water is intensively mixed with ozone due to turbulization, which is provided by the location of the partitions. Purified water exits through pipe 3, and the excess

air when reaching a predetermined pressure leaves through the safety valve 6.

Thus, the proposed device for mixing ozone with water provides efficient mixing and is more reliable compared with the known.
