Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention removes foreign substances such as organic substances, free chlorine, and organic solvents from water by sterilization, oxidation, decomposition, deodorization, various degassing, adsorption filtration, etc. It is a device that performs multiple simultaneous treatments for rust prevention, scale removal, and purification of boiler water, sterilization, rust prevention, algae prevention, and purification of cooling circulating water for cooling towers, sterilization and purification of drinking water in water receiving tanks and elevated water tanks, and piping. Concerns rust prevention and scale removal from systems, corrosion prevention and purification of metal cutting fluids, etc.

[Prior Art] Various purification devices for water sterilization, degassing, filtration, etc. have been developed, but each treatment function is an independent device and is processed separately, making the treatment process complicated and difficult to handle. Maintenance was a concern.

Among these, the oxidative decomposition of foreign substances such as organic matter and free chlorine is attempted to be solved by ozone oxidation alone, which is called advanced treatment, so a huge amount of ozone is required, and the surplus ozone is toxic, so the disposal method is unknown. Regarding degassing technology, there is a device that uses a functional membrane to degas with a vacuum pump.
Simple degassing devices that use pumps with strong suction force have many problems, such as clogging of the functional membrane, which makes maintenance difficult, and simple degassing devices using pumps with strong suction power, which have a slow degassing rate and too little amount of degassing per unit energy.

[Problems to be Solved by the Invention] The present invention was developed in view of the above-mentioned matters, and by stirring and reacting ozone with foreign substances such as organic substances, free chlorine, and organic solvents in water, and then irradiating it with ultraviolet rays, By forcibly promoting the oxidative decomposition reaction, and then performing a combined simultaneous process of high-speed oxidative decomposition, degassing, and adsorption filtration in a high-vacuum container, the decomposition ability and degassing amount of organic substances, free chlorine, organic solvents, etc. can be improved. The purpose of the present invention is to provide a multi-processing device that is easy to handle, compact, space-saving, and has high labor-saving efficiency.

[Means for Solving the Problems] The configuration of the present invention will be explained based on the drawings.
In the figure, an ultraviolet lamp 4 or an ozone generator 1
Stir and mix the ozone generated in step 4 and the treatment water, irradiate it with ultraviolet light using the ultraviolet lamp in step 4, and suck and introduce the water into the highly vacuum degassing adsorption filter tank 1. , a high-speed oxidation decomposition reaction degassing device that performs a forced oxidation decomposition reaction of organic solvents etc. in a high vacuum and at the same time extracts various soluble gases from the water using a vacuum pump 7, and an adsorption filtration filter 2 in the same tank. , high-speed ozone ultraviolet irradiation oxidation decomposition reaction treatment, degassing treatment, adsorption filtration treatment, respectively.
They are housed in series in the same device so that they can be performed almost simultaneously.

[Function] The present invention has the above configuration, and when it is used,
By injecting ozone gas from the position specified in Figure 1, the oxidative decomposition capacity has been increased by performing multiple simultaneous oxidative decomposition processes for foreign substances such as organic matter, free chlorine, and organic solvents in water. Degassing, especially removal of dissolved oxygen amount, has been accelerated as shown in the graph in Figure 2, and the adsorption filtration filter shown in Figures 1 and 2 has been improved by the combined simultaneous degassing treatment of the 1st, 2nd, and 3rd treatments. The lifespan of the product has been extended several times, reducing running costs, making the device itself smaller, and drastically reducing the installation space.Furthermore, the simultaneous sterilization by ozone mixing/degassing and ultraviolet sterilization has a strong sterilizing effect. and works effectively.

[Example] Next, an example of the present invention will be described based on FIG.

The ozone gas generated by the ultraviolet lamp (4) or the ozone generator (14) is mixed and sucked by the ozone injection device (3), and the organic matter, free chlorine, organic solvent, etc. in the water (6) is subjected to high-speed sterilization photooxidation in the ultraviolet irradiation unit 5. A decomposition reaction is carried out, and the degassing is introduced into a degassing adsorption filtration tank 1 (vacuum level 60 Torr to 20 Torr), oxidative decomposition of organic matter is carried out under reduced pressure, various soluble gases are simultaneously degassed and removed by a vacuum pump 7, and the molding of 2 is carried out. Decomposed organic substances, odors, etc. are adsorbed and filtered by the filtration/adsorption filter, which passes through line pump 11 and reaches lO. Also, the water level at 9 is adjusted using the pole tap at 8.

As shown in 2 above, the water entering from 6 is instantly subjected to sterilization, photooxidative decomposition, degassing, filtration and adsorption using ozone and ultraviolet rays.
It reaches 0.

[Effects of the Invention 1] Since the present invention has the above-described configuration, it is a device for preventing scale adhesion and red rust on water piping lines by combining what is commonly called advanced treatment sterilization and purification, a degassing device, etc. It is used for water tanks for buildings, people/human waste, etc., elevated water tanks, water for boilers, cooling water for cooling towers, removal of iron and organic solvents from drinking underground water, production of raw water for soft drinks, and mechanical cutting.
