Description

The utility model relates to devices for water treatment and water purification, in particular, to the processes of coagulation, saturation with liquid and gaseous components, and disinfection of drinking and waste water in pipelines and pools for treating drinking and waste water.

A system is known for disinfecting water, which comprises a dosing unit, pressure and reagent manifolds and hydroacoustic emitters, rigidly mounted in the pipeline and oriented so that the axis of the output channels are parallel to the axis of the pipeline, and the stream of purified water is associated with the flow exiting the hydroacoustic emitters (RU 2125973 C02F 1/72, 1999).

The disadvantage of the described system is the low efficiency of mixing the reagents with the flow of water, because the acoustic flow turns out to be a concurrent flow of the treated water, as well as the impossibility of a quick change of emitters in the event of their failure due to the rigidity of the mount and the inability to disassemble the installation. In addition, this system does not provide for the supply of coagulant, which reduces the overall degree of water purification.

A known method of water purification, including its treatment with an oxidizing agent and a coagulant with simultaneous intensification of the purification process using acoustic exposure (L. A. Kulsky "Theoretical Foundations and Technology of Water Conditioning", Kiev, 1983, p. 322, 323).

However, this source of information does not describe the reagent supply system and the installation of the source of acoustic vibrations, which provides effective mixing and, as a result, the minimum consumption of reagents with a high degree of purification.

The closest in technical essence and the achieved result is a method of water purification, including its treatment with an oxidizing reagent and / or coagulant under the influence of acoustic vibrations, while the oxidizing reagent and / or coagulant are supplied through resonator chambers of hydroacoustic emitters due to the discharge created by the streams of purified water passing through the said emitters, while the emitters are oriented so that the acoustic flux generated by the emitters is directed towards in the treated water stream, and the axis of emitters outlet nozzles are arranged at an angle of not less than 7 ° from the direction of flow and cleaned from the perpendicular to the direction of flow to be cleansed, said cleaning being performed at a sound pressure thresholds (RF Patent 2165891, publ. 2001.04.27).

A water purification device, by mixing a coagulant and / or chemical reagent with water, contains a main pipeline, inside which a piping for supplying a chemical reagent and a pipe for supplying pressurized water with a collector are vertically installed through the docking station, the end of the pipeline for supplying a chemical reagent is connected to a collector, which in turn is connected by flexible hoses with nozzles for introducing a chemical reagent, and on the collector for supplying water to the main pipeline sonar emitters with sonar holes, which are located under the chemical inlet pipe, are rigidly connected to them and directed at an angle relative to the axis of the main pipeline.

The disadvantage of this device is that the reagent is supplied by "pulling through the resonator chambers of hydroacoustic emitters", which leads to:

- to the dependence of the supply (flow) of the reagent on the design of the hydrodynamic emitter and on the parameters (flow, pressure) of the flow of water passing through the emitter;

- the need to place a collector inside the main pipeline for supplying reagent and flexible hoses for supplying the reagent to each sonar emitter, which, in turn, leads to a complication of the design and to a decrease in its reliability due to the use of connections with flexible hoses inside the main pipeline.

The technical result of this device is:

- independent supply of coagulant (reagent) and water to hydrodynamic emitters in the main pipeline;

- the ability to control the supply (flow) of the coagulant (reagent);

- the ability to control the mixing process of the coagulant (reagent) with water in a wide range of frequencies of hydroacoustic vibrations and sound pressure.

The technical result is achieved by the fact that the device consists of two independent vertically installed pipelines (coagulant supply and water supply to hydroacoustic emitters), permanently fixed to the flange plug of the main pipe branch pipe. The water supply pipeline is connected to a U-shaped collector with sonar emitters located on its inner sides (at least 2 on each side). Hydroacoustic emitters are arranged in pairs on common axes and directed by sonar holes towards each other. The free ends of the U-shaped collector are muffled. A U-shaped collector is installed horizontally in the main pipeline. The coagulant supply pipe also has a horizontal coagulant inlet pipe placed between the first two (from the water supply side) hydroacoustic emitters. In this case, the axis of the coagulant inlet pipe is located below (3 ... 5 cm) the axis of the sonar holes of sonar emitters.

The drawing shows a water purification device by mixing the coagulant with water.

A device for water purification consists of the following elements: a pipeline for supplying water to the emitters (1), including a pipe for supplying pressurized water to the emitters (2), a valve (3), a pressure gauge (4), a docking unit with a U-shaped collector (5), U-shaped collector (b), sonar emitters (7), plugs (8), coagulant supply pipe (9), including a coagulant supply pipe (10), valve (11), pipe for horizontal input coagulant (12). Pipelines (1) and (9) are stationary mounted on the flange plug (13) of the pipe branch (14) of the main pipeline (15).

It is possible to install the device on the branch pipe of the main pipeline using a lock chamber with Wilson seals and a locking device that allows you to remove the device without stopping the main water (similar to the method described in RU 2165891 C1).

The device operates as follows.

Water under a pressure of at least 3 atm is supplied to pipeline 1, while hydroacoustic emitters 7 emit sonic vibrations at the outlet of the hydroacoustic emitters 7, which are transmitted to the surrounding space, creating a sonar field in the treated water of the main pipeline with sound vibrations of a certain frequency and sound pressure. The coagulant through pipeline 9, entering through the pipe for horizontal introduction of coagulant 12 into the main pipeline 15, enters this hydroacoustic field, disperses into the smallest particles, mixes with water and spreads (distributed) over the entire volume of treated water of the main pipeline section in the area of the device, which contributes to the most complete contact of the coagulant particles with the treated water and its most effective cleaning.

The proposed device design has several advantages over known devices:

- Improving the effectiveness of the effects of hydroacoustic vibrations directly on the fluid flow with the simultaneous introduction of a coagulant into it with a uniform distribution of the reacted coagulant throughout the volume of the liquid being cleaned;

- Providing an intensive process of water purification in unlimited quantities;

- The ability to control the process of mixing the coagulant with water, depending on the degree of water pollution (independent supply of coagulant to the main pipeline and water to sonar emitters);

- Reduced coagulant consumption depending on the degree of water pollution;

- Increased service life, reduced maintenance costs.
