Description

Contact camera

The inventive utility model is used as a part of devices designed for treating surface and underground natural waters by oxidizing water-polluting substances with ozone, and can be used to purify, clarify, and disinfect water in various drinking water treatment plants.

Known contact chamber used in the installation for purification and disinfection of water, which is a closed container with a mixing unit, made in the form of an impeller, the tank is equipped with input devices for the ozone-mixture and source water installed in the lower part, output devices for the spent ozone-air mixture and processed water placed at the top and shutoff valves. A.S. USSR No. 1002255, MKI C02F 1/78, 1983

When using the known contact chamber, the required quality of water treatment and the possibility of operational regulation of the quality of water treatment depending on needs are not provided.

Closest to the proposed one is a contact chamber, which is a tank equipped with a displacement unit, filled in the form of a bubble grating located in the lower part of the chamber, the tank is equipped with input devices for the ozone-air mixture and source water installed in the lower part of the chamber, and devices for the output of spent ozone - air mixture and treated water located in the upper part, and shutoff valves, which is a reducing valve to create pressure in the chamber above atmospheric pressure. Utility Model Certificate of the Russian Federation No. 3603, IPC 6 C 02 F 1/78, 1997

The well-known contact chamber provides high quality preparation of drinking water, however, it is characterized by high energy consumption and high ozone consumption.

intensify the cleaning process and ensure high quality water treatment while reducing energy consumption.

The problem is solved in that the proposed contact chamber is a container with a mixing unit, equipped with input devices for the ozone-air mixture and feed water through the ejector-mixer installed in the upper part of the chamber, devices for removing the spent ozone-air mixture and treated water, placed in the upper parts of the chamber, and shutoff valves, while the mixing unit is made in the form of a pipe built into the contact chamber, the input of which is dispersed in the upper part and connected to the ejector-mixer, and the output is nen open and that serves in the lower part of the contact chamber. The output of the mixing unit is in the form of an umbrella. The mixing unit is equipped with an opening to prevent the formation of an air plug, placed in the upper part of the contact chamber below the liquid level. The output device for the spent ozone-air mixture consists of a degasser and a reducing valve.

Comparison of the proposed camera with the known allows us to conclude that the proposed solutions meet the criterion of "Novelty. A unit for mixing the ozone-air mixture and water installed inside the contact chamber divides the contact chamber into a zone providing a turbulent mode of flow of the mixture, which makes it possible to intensify the process of its mixing and dissolution of ozone in water, and the settling zone, where the process of oxidation of the impurities contained in the water takes place directly. This design provides optimization of mixing and displacement processes as a bubble column, stabilizes the phase contact time, which allows to increase the ozone dissolution efficiency by 20-25% and to reduce the consumption of the ozone generator by 400 W per 5 m of treated water.

The proposed camera is illustrated in the drawing.

The chamber is a closed container 1 with an integrated mixing unit 2, input water input devices 3, for example, a pump (not shown in the drawing), and an ozone-air mixture 4, an ejector-mixer 5 located in the upper part of the chamber and connected to the input of the mixing unit 2, the output device of the treated water 6 and the output device of the ozone-air mixture, consisting of a degasser 7 and a reducing valve 8, providing a pressure in the chamber above atmospheric. The output of the mixing unit is equipped with an umbrella 9 for uniform distribution of the ozone-air mixture flow in the processed water after mixing. Mixing knot

equipped with a hole 10 to prevent the formation of an air plug, which is located below the level of liquid 11 in the chamber.

The proposed device operates as follows.

When the ozone generator and the source water pump are turned on, the ozone-air mixture and the source water through the transport lines of the source water input device 3 and the ozone-air mixture 4 enter the ejector-mixer 5, where it is mixed, forming an aerosol. From the ejector-mixer 5, the aerosol enters the built-in bias unit 2, in which ozone is dissolved in water and through its open outlet 9, the aerosol enters directly into the contact chamber 1, where the contaminants in the water are oxidized and disinfected. The spent ozone-air mixture through the outlet pipe equipped with a reducing valve 8 enters the degasser 7, and the treated water is discharged through the outlet pipe 6.

The inventive chamber for drinking water treatment devices using the ozonation method allows to intensify the water treatment process, increase its treatment efficiency, increase the ozone utilization coefficient by improving its solubility by 20-25%, reduce the energy consumption of the ozone generator by 400 W for every 5 m3 of treated water.
