Description

 Deep sea water distillation apparatus

The present invention relates to a method for producing mineral water containing mineral components beneficial to the human body from deep sea water by applying a magnetic force simultaneously with ozone injection to deep sea water (raw water).

The conventional treatment method using ozone is a method of dissolving ozone in water once and reacting the dissolved ozone with the oxidized substance in water. Specifically, ozone is dissipated in water as fine bubbles in an acid substrate provided at a lower portion of a large water tank. In order to dissolve as much ozone as possible, the depth of the water is deepened and the bubble is made small. However, for practical use, the water depth is 5 to 6 m and the size (particle size) of the bubble is limited to about 20 μm. In addition, a residence time of about 8 to 10 minutes is required before the reaction, and an ozone melting tank or the like is required, and the equipment itself is enlarged.

However, even when using such a facility, the utilization rate of ozone is about 60 to 80%. On the other hand, in the case of water containing both of the representative inorganic oxides and organic substances such as soluble iron and manganese, the relatively well oxidized minerals are preferentially oxidized when ozone is injected, and the oxidative decomposition of organic matters does not proceed very much. For this reason, colloidal substances are produced when the inorganic material is oxidized, which consumes ozone, and the amount of ozone necessary for oxidatively decomposing organic matter becomes several times as necessary for the original treatment.

In order to solve the above-mentioned problem, ozone may be injected again after removing the colloidal substance. However, this colloidal substance has a submicron particle size, and thus it is difficult to remove it as it is. do. Therefore, this treatment method requires equipment such as a flocculant addition facility and a reaction tank, and there is a problem that waste is increased by adding a flocculant. Accordingly, an object of the present invention is to provide a compact treatment method and treatment facility capable of purifying water without adding a flocculant and improving ozone utilization efficiency.

In order to solve the above-mentioned problems, the treatment method of the present invention, by applying a magnetic force to the water to be treated, injecting ozone to oxidize and agglomerate the blood oxide, and then remove the aggregated material by filtration, and once again A magnetic force is applied to the water to be treated and ozone is injected, and then a catalyst layer made of activated carbon is passed through to filter and remove the flocculant. In addition, the treatment facility of the present invention injects ozone generated by the first ozone generator into the water to be treated by the magnetic treatment unit and the magnetic treatment unit which draws the first and second ozone generators and the water to be treated. A first magnetic treatment reactor composed of an ozone injection mixing unit for mixing, a first filter for removing agglomerated substances in the water to be treated in the first magnetic treatment reactor, and a water treatment from the first filter to draw a predetermined magnetic force. A second magnetic treatment reactor composed of an ozone injection mixing unit which injects and mixes ozone generated from the second ozone generator to the water to be treated in the magnetic treatment unit, and draws the treated water from the second magnetic treatment reactor. It is composed of a reaction tank for oxidizing and decomposing with a catalyst layer made of activated carbon and a second filter for removing aggregates in the water to be treated.

According to the configuration of the treatment equipment described above, suspending substances generated by oxidizing colloidal substances and organic substances generated by oxidation of inorganic substances by applying a magnetic force when oxidizing the water to be treated with ozone. Can be aggregated without using a chemical such as a flocculant.

In addition, the wing body provided in the ozone injection mixing portion of the magnetic treatment reactor is composed of a pair of semicircular wing plates, and the two wing plates are inclined at a predetermined angle with respect to the flow direction of the water to be treated and twisted in opposite directions. It is arranged so that it is arranged so as to separate the front space part of the intersection of these two wing plates to the left and right. The projection body is composed of a columnar portion fixed to the inner wall surface of the mixing cylindrical body and a mushroom-shaped portion formed at the tip of the columnar portion, and a plurality of protrusions are arranged in a zigzag shape on the inner wall surface of the mixing cylindrical body.

According to the configuration of the ozone injection mixing portion, the pair of blades arranged in the mixing cylindrical body divides the water to be treated and twists in the opposite direction to each other. The downstream projections change the flow in the radial direction of the mixing cylindrical body while further dividing the flow. As a result, a severe collision effect occurs in the water flow, and ozone reacts with the treated water quickly.

According to the present invention, it is possible to improve the utilization efficiency of ozone in the seawater desalination process using ozone to produce high purity mineral water at low cost energy, and to provide a compact treatment method and treatment facility.
