Description

Laser device for contaminated water purification

On the other hand, great expectations have been made for the structured range of lasers, but this does not complete the corresponding experimental application. Since ceramics need to be heated to a temperature of several hundred degrees, they require excessive consumption of electrical energy. In addition, the fact that the heating of the ceramic must be constant involves the reduction of the amount of oxygen dissolved in the water, which may cause a decrease in water quality. For the use of ozone, although it is a strong reagent, it is less suitable for use in drinking water because of its function as an oxidant. For chlorination, chemical reagents that degrade the water must be introduced into the water, even with the use of infrared radiation, bacteria and other microorganisms can be removed without causing this effect. In view of the reasons disclosed above, the present invention shows an improvement related to the prior art.

While the use of ultraviolet radiation is insufficient when the degree of contamination of the water exceeds a certain limit, infrared radiation has a greater destructive power and has not been used conventionally, but propagates wider in water as described in the present invention. In some cases, ceramics emitting infrared radiation are used in combination with magnetic effects, but no laser has been used within the limits disclosed in the present invention.

EXAMPLE

FIG. 1A shows the location of two magnetized plates as they pass and flow close to the water pipes and spread to their surface to attract and hold metal particles to be held by the magnetized plates. These plates can move so that by exerting a stronger magnetic attraction to the metal contaminant particles deposited on the plate I, the plate I ₂ can remove the metal trapped by the plate I. The magnetized plate is fitted to a slide device having a track that moves automatically. The water is then irradiated with a neodymium laser of wavelength (λ) = 1.06 μm , which is mounted on the support S and can be positioned close enough to the water surface to purify the water, for this purpose a CO ₂ laser and / or Alternatively, it is possible to employ a neodymium laser (Fig. 1A).

In FIG. 2, water flows into deposits receiving infrared radiation of wavelength [lambda] = 1.06 [ mu ] m , where wavelengths in the infrared spectrum between the limits of 0.8 [ mu] m and 11 [mu ] m can be used.

The bottom of the deposit is constructed of plates made of white aluminum (Al), copper (Cu) and other materials that reflect at these infrared wavelengths. These materials are advantageous for reflection and have the effect of amplifying the purifying action of neodymium laser radiation. The laser remains fixed and opens to various widths, allowing it to cool the air a _f , which creates instability in the air, warms up the elevated air a _c and oxygenates the surface of the water.

In FIG. 3, the diffusion lens may be formed of another material that transmits infrared radiation such as CaF ₂ , SeZn, germanium, and the like. Located here is a magnetized plate L that can move in a sliding device with a track. These magnetized plates collect metal impurities, their approach being favored by the diffusion instability produced by the infrared radiation laser of wavelength λ = 1.06 μm .

In FIG. 4, the water pipe extends into the widened zone. It has a magnetized plate in the downstream section that repels lead particles, and also has a filter F _IA which is structured as a network of micropores through which water passes. Repelled in such a way that the particles are deposited. Open the channel with the periodically widening part and send the collected lead to the sedimentary layer located in the downstream area marked with prismatic shape in FIG. Deposition layer has a smaller magnetization of the outlet filter F _'IA for resisting the lead particles. This filter is located at a predetermined height from the bottom and has a small volume of water flowing out of it. Water with a high concentration of lead can be separated and stored.

The device uses an infrared radiation spectral laser that includes a pulsed or continuous wavelength neodymium laser (neodymium pumped diode) and a CO ₂ laser. It is characterized by the use of infrared radiation spectral lasers, always within the 0.8 μm -11 μm limit, with absorption coefficients smaller than CO ₂ lasers. These lasers are located on the surface of the water and convective thermal instability is produced by neodymium radiation to generate a flow that occurs at the surface as the density decreases, where it is superpurified by a CO ₂ laser. Prior to this, contaminants in the volume of water are already partially removed by the neodymium laser. It is also possible to use neodymium lasers independently. In this case, it is possible to use CaF ₂ lenses or other transparent materials for the radiation of neodymium lasers.

When an ultraviolet laser is equipped with a neodymium laser, the neodymium laser produces a diffusion instability that rises to the surface, and the ultraviolet laser mixes ozone produced by oxygen in the air with the body of water that rises continuously from the surface, thus producing ozone in the volume of water. And a complex purification effect mediated by the action of neodymium laser. As a result, bacteria, fungi and viruses are eradicated, water can be dechlorinated and subsequently employed for the production of carbonated beverages and for other uses.

It is deemed unnecessary to make further explanations to those skilled in the art to understand the scope of the present invention and the advantages obtained from the present invention. The material, shape, size, and arrangement of the elements may be changed without changing the integer of the present invention.

The terminology described herein is always to be taken in a broad sense and should not be limited.
