Description

(INNER INJECTION TYPE OZONE WATER MIXER FOR PIPELINE)

The present invention relates to an ozonated water mixing apparatus connected to a conduit 19 of a water treatment facility for injecting and mixing high concentration ozonated water into a conduit 19 and comprises a branch pipe 20 branched from a main pipe 10 connected to the pipe 19, An ejector 40 that mixes the ozone with the classification treatment water fed from the feed pump 30 to generate high concentration ozonated water; A re-supply pipe 25 which connects the discharge port of the main pipe 10 to the main pipe 10 to supply the high concentration ozone water discharged from the ejector 40 to the main pipe 10 and a nozzle 60 and a transverse pipe 50 connecting the nozzle 60 and the re-supply pipe 25 so as to eject the high concentration ozonated water generated in the ejector 40 from a central portion of the main pipe 10, .

Of the ozone treatment facilities constituted in various water purification facilities and lower and wastewater treatment facilities, the ozone treatment facility connected to the pipeline 19 directly supplies ozone to the transfer pipe 19 of the treatment water without holding the treated water in a separate reaction tank The ozone treatment apparatus of the connection type of the conventional industrial pipeline (19) classifies a part of the treated water in the pipeline (19) by connecting the piping or piping for injecting high concentration ozonated water and mixing the ozone with the treated water in the pipeline (19) The ozonated water is once again supplied to the conduit 19 after the branched ozone water is once formed by mixing the ozonized water with the classified treatment water, , And related related art is Japanese Patent No. 1213819.

1, the conventional ozone treatment apparatus connected to the pipeline 19 including the patent No. 1213819 includes a branch pipe 20, a feed pump 30, an ejector 40, The supply pipe 25 is connected to connect the treated water for high concentration ozone water treatment and classify and supply high concentration ozone water.

That is, in the conventional ozonation apparatus connected to the pipeline 19, when a part of the treated water is classified into the branch pipe 20 branched from the pipeline 19, the feed pump 30 separates the treated water into the ejector 40, Concentration ozonated water discharged from the ejector 40 is supplied to the ejector 40 through the ejector 40. The ejector 40 is connected to the ejector 40 through the ejector 40, And a re-supply pipe 25 connecting the pipe 19 to the pipe 19.

Thus, the high-concentration ozonated water is once produced without removing the gaseous ozone directly to the conduit 19, and then the high-concentration ozonated water in the liquid state is re-supplied to the conduit 19, Concentration ozone water is supplied through a re-supply pipe 25 of a simple joining pipe type directly connected to the pipe wall of the pipe 19, , There is a problem that uniform diffusion of the ozonated water in the treatment water across the entire cross section of the channel 19 can not be expected.

Concentration ozonated water injected into the conduit 19 through the re-supply pipe 25 is temporarily stuck to the inner surface of the pipe wall of the conduit 19 and then only the center-side diffusion component of the conduit 19 flows into the conduit 19, It is not possible to expect rapid homogeneous mixing over the entire cross section of the channel 19 because the water is transported in the longitudinal direction in accordance with the transport of the treated water in the channel 19.

That is, the treated water in the conduit 19 has a flow velocity distribution in which the flow velocity decreases from the central portion of the conduit 19 to the tube wall side. Particularly, in the vicinity of the conduit wall of the conduit 19, Since the re-supply pipe 25 has a simple merge structure directly connected to the pipe wall of the pipe 19, the high-concentration ozonated water supplied through the re-supply pipe 25 can not be rapidly diffused over the entire cross section of the pipe 19 Concentration ozone water supplied to the conduit 19 only performs unidirectional diffusion toward the other side wall from one side wall on the transverse side of the conduit 19 to cause an unbalance in the ozone concentration in the conduit 19, There is a problem that is biased.

Particularly, such imbalance in the dissolved amount of ozone in the treated water is accompanied not only by a reduction in treatment effects such as disinfection and purification of treated water, but also in a portion where ozone is excessively biased, causing a serious problem in which excessive ozone is released, do.
