Description

 SYSTEM TO OBTAIN STERILE WATER WITH HIGH CONTENT OF

OXYGEN

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of electronics and water treatment, because it provides a system to obtain sterilized water with high oxygen content, which can be used in various applications, such as disinfection of objects, for agricultural use, etc.

BACKGROUND OF THE INVENTION

At present, the use of ozone in water purification is well known, for which devices that generate ozone gas are used which do so by means of ultraviolet light and by means of high-voltage electric discharges.

On the other hand, the use of ultraviolet rays as liquid sterilizers is widely documented. However, these devices are implemented separately.

As can be seen in the patent ES 2004162, it details a high frequency ozonator to ozonize air, by means of silent discharges, which consists of two concentric tubes, open on its sides, and yet they are quenched together to pass through separated the air or oxygen and the cooling fluid and two electrodes placed coaxially and concentrically to the two tubes. Because the inner electrode is made in the form of a spiral and attached to the high voltage and the outer tube is made as a ground electrode and the water serves as a refrigerant and because the inner one is made of quartz glass or other permeable material to ultraviolet rays and heat resistance. For its part, patent document ES 2150490, describes a water purification apparatus that has a source of UV radiation, which is an elongated lamp to eliminate microorganisms present in the water to be purified, this water passes through a filter to separate all the particles and materials of the water, later it is irradiated by the UV lamp, to eliminate any organism that has passed from the first radiation,

In patent document US 6881331 B1 a system for purification of water based on ozone is described, which comprises a venturi mixer that injects ozone and a sanitizing liquid in a water jet to be treated, subsequently the sanitized water jet and Ozonized passes to a contact region, where ozone and sanitizer react with contaminants and microorganisms. The flow is mixed by several mixing devices to obtain ozone and residual sanitizer, to react with said contaminants and microorganisms. Particularly an anti-flow system is employed where the flow is directed downwards to several points, such that the bubbles containing ozone are forced to flow upwards contrary to said flow, where the contact time of the ozone is prolonged. An ultraviolet lamp is also used to generate ozone and is mounted in such a way that the ultraviolet light is exposed to the flow of water, providing extra sterilization effects. Additionally a mixing venturi is provided to mix the ozone-containing gas and the sanitizing liquid into a flow of driven water. One of the drawbacks of this system is the use of a sanitizer, which makes the water purification process more expensive; as well as a greater expense of electrical energy is required by the use of ultraviolet light lamps for the generation of ozone.

With the purpose of eliminating the aforementioned drawbacks, a novel system was developed to obtain sterilized and oxygenated water at the same time, which I describe below. DETAILED DESCRIPTION OF THE INVENTION

The characteristic details of this novel system to obtain sterile water with high oxygen content, are clearly shown in the following description and in the accompanying figure, which is mentioned by way of example and should not be considered as limiting for the present invention

Figure 1 is a schematic diagram of the system for obtaining sterile and hydrogen peroxide, in its simple form.

Figure 2 is a schematic diagram of the system for obtaining sterile and hydrogen peroxide, in its most sophisticated mode.

The idea of this invention is to obtain a system that performs the functions of generating ozone from ambient air and sterilizing "raw" water. Therefore, one of the main purposes of this system is to obtain sterile water, with high oxygen content, for multiple uses, such as in agriculture.

Therefore, said system is made up of two entrances or sections, one for ambient air to convert it into ozone (O3) and in the other one enters "raw" water to be sterilized.

In a simple mode of the system (figure 1), the section that processes "raw" water is provided with a "raw" water inlet 1, which joins a sensor 6 that measures the degree of turbidity of said "raw" water ", with the purpose of knowing how dirty the water is, since the idea is not to use very polluted or very dark waters; next is an ultraviolet (UV) 7 camera, which applies a wavelength radiation of 275 nM, to the water to sterilize it; Finally there is a venturi 8 mixer to mix the sterilized water with the ozone that is produced in a section where ozone is generated. -A- The section where ozone is generated consists of an ambient air inlet

9, which is attached to a turbine that injects air 10, which is attached to an air filter 11, to retain the solid materials contained in said ambient air; later there is an ambient air dehumidifier 12; Next there is an oxygen concentrator 14, to separate and concentrate only the oxygen molecules contained in the ambient air; an ultraviolet pre-ionization chamber 15 is then added, to apply a wavelength of 190 to 250 nM to the oxygen flow to make a first ionization of the molecules and thus begin a first stage of formation of ozone molecules ; subsequently, a conventional high voltage reactor 16 is adhered to convert those molecules that were free in the first ionization into ozone; Finally, ozone is transported to the venturi mixer 8, to mix with the sterilized water, which travels to an exit 19, to be used for final use, where when colliding with microorganisms, and solid materials; or when changes in temperature, light, etc., the ozone molecules break down and cause a large amount of oxygen in sterile water.

Both sections are controlled by means of a control circuit 17, in which the ozone generator 16 is connected, to receive the energy used for ionization. This control circuit is powered by a power source 18, which can be direct electric current, an electric or solar battery.

In this way we achieve a simple system to obtain sterile water with high oxygen content, where the novelty consists of the combination of an air pre-ionization chamber 15 and a conventional high voltage reactor 16, with which a first is given Ionization of oxygen, and then complement the ionization of all oxygen. With this combination there is an energy saving, since the conventional high voltage reactor 16 will not require much energy, as would normally happen, thanks to the previous function played by the pre-ionization chamber 15. However, the simple system described can have several modalities, to make its operation more efficient, which is why it is described below with the support of Figure 2, which are those variants:

In this case, the section that processes the "raw" water, has after the entry of "raw" water 1, a filter 2 to remove solid materials containing said "raw" water.

It is also possible to add, after filter 2, a flow meter 3 with an electrovalve containing a flow sensor to dose the water flow.

A water cooler 4 can be added, after the flow meter 3, so that it is responsible for lowering the temperature of the water flow in order to always keep it cold, so that when it is mixed with ozone, it does not degrade rapidly; whereby said water cooler 4 carries a temperature sensor 5 that activates the cooler 4 when the temperature of the water jet increases.

The following elements of the water cooler 4 are the same as those described in the simple system (figure 1).

As for the section where ozone is generated, only a flow sensor 13 with electro-valve is attached later to the air dehumidifier 12, to dose the air passage; and all the components that follow later, are the same already described in the simple system.

Therefore, in these modalities, the high voltage control circuit 17, the water cooler 4 with its respective temperature sensor 5 and the air flow sensor 13, are also connected to the high voltage control circuit, to receive the energy that they will need to carry out their functions. The system for obtaining sterile and oxygenated water, achieved with these variants, in addition to the advantages already mentioned of the simple system, is that the amount of "raw" water and ambient air to be treated can be dosed, according to the desired need; In addition, keeping the water temperature low is of great help because there is no waste of ozone, which we know that at a higher temperature, the O3 molecule is broken.

On the other hand, because the water obtained by this system is sterilized and when mixed with ozone it lasts longer, because there are no microorganisms or other solids that could interfere with the ozone molecules, in addition, thanks to the cooler of temperature, energy is also saved, since it is well known that at a higher temperature, more energy is required for ozone formation.

Another of the advantages of the water produced is that when it is saturated with ozone molecules, they break when they collide with some obstacles encountered during the course of the water to its final destination, thus forming large amounts of oxygen, which is used , for example, by the plants, when it is used as water for irrigation.
