FIG. 5 is a schematic side view of another device according to the invention.

FIG. 6 is a schematic enlargement of a microdiffuser used in another device according to the present invention. It's a big picture.

Referring to FIG. 1, a generally conventional ozone chamber 10 is connected to a source of pressurized air. For example, an ozone chamber lO typically has an output of approximately 1850 It has an ozone lamp (not shown) such as a mercury lamp. The output of this lamp is , converts the oxygen contained in the air in the chamber IO into ozone. Chamber IO output Force 11 exhausts this mixture into the atmosphere to provide a mixture of ozone and air. connected to output 12 with a valve for use in other processing equipment or connected to a diffuser 13, which is shown in detail in FIG.

A water reservoir 14 and a drain 15 are provided to remove accumulated condensed water vapor from time to time. Collect and remove.

The diffuser 13 is a porous and inert micro diffuser element 1. 6, and on the top of the micro diffuser element 16, ozone is applied under pressure. and air, and the mixture is discharged into the ultraviolet chamber 18. Ozone is thus evenly distributed throughout the air mixture. Process The fluid to be treated is drawn into the device via port 17 and supplied to ultraviolet chamber 18. It will be done. Discharge the ozone mixture into the ultraviolet chamber 18 via a diffuser This ensures that the ozone mixture is thoroughly mixed with the fluid to be treated. chamber 18 has a mercury lamp (not shown), and this mercury lamp connects the fluid in the chamber with ozone. The mixture is irradiated with ultraviolet light as it passes towards the outlet 19 of the device. do. The fluid leaving outlet 19 is fully treated and contains no ozone. not present.

As explained below, when ozone enters the diffuser, or before it enters the It is also possible to further mix another fluid into the mixture of air and air.

In its simplest form, the method and equipment for treating this liquid include ozone treatment. It is equipped with both physical and ultraviolet treatment at the same time. Ozone is used for fluid treatment, especially for sterilization. Already known for its use. Similarly, sterilization processes using ultraviolet radiation are currently It has now been put into practical use. However, previously, the present practice was mixed with ozone. In the example, the proposal to irradiate a thoroughly mixed fluid to be treated with ultraviolet light is , had not been done. Therefore, ultraviolet rays are “ozone rich” (ozone rich). )” is actually surprisingly more effective overall by being irradiated into the fluid. A processing process can be obtained.

A typical device that can produce satisfactory results will produce between 80 and It has a fluid flow rate of 500 liters. Amount of ozone produced and used is about 15 grams per minute (to generate ozone and irradiate ultraviolet rays) The total power consumption is approximately 500 to 800 watts, and each This corresponds to the two flow rates mentioned above. An advantage of embodiments according to the invention is that ozone is destroyed by irradiation with ultraviolet light. This method eliminates all the residue remaining in the mixture. can be easily configured to constantly destroy all ozone within the chamber 18. I can do it. In processes where ozone is used alone, during sterilization or processing. the oxygen or oxides are not used (i.e. destroyed) and are flushed away after processing. To prevent ozone from being removed from the body or from being present in fluids , special care is required. This may be returned to the system for food or use. ozonation of fluids used (e.g. fish tank water) is not always possible. meaning that it must be carefully controlled and not . Even if this is not the case, ``unused'' ozone can damage healthy tissues and plants. Oftentimes, damage can have negative effects. Therefore, conventionally, generally A small amount of ozone is used for practical purposes. Additional steps were required in the process.

While the above description has been made with respect to a typical device, it is equally possible that the present invention Small units, e.g. fluid flow rates exceeding io, ooo liters per minute It should be noted that it is applicable to larger units. Corresponding o The increase in consumption of Zon is on the order of 200 to 300 grams per hour. actual The amount of ozone used and the amount of ultraviolet rays irradiated are determined depending on the purpose.

The apparatus shown in FIGS. 3 to 6 includes two ozone chambers 20.21 and It has two UV chambers 22,23. Each chamber has two sides. Upper elongated lamps (not shown) are provided which are connected to the seal within the chamber. in a manner known per se. Irradiate the inside of the chamber with ultraviolet light. Chamber 20.21 is supplied with air. Ozone is produced from this air during use. Also, this air is Ozone is delivered to chamber 22,23 as detailed in . Chambers 22 and 23 are , connected in parallel by tubes, at the inlet end receiving the fluid to be treated and at the output end, Drain the treated fluid. Other conventional parts shown in the drawings do not correspond to the present invention. It is not a direct constituent requirement.

Micro diffuser integrated with ceramic particles or ceramic fibers A diffuser 24 with an element 25 is located at the inlet end of the chamber 22.23. Adjacent to these sides, the air along with ozone enters the chamber 2. 2.23 is supplied to the diffuser. Therefore, the ozo that entered the chamber The particles are effectively dispersed or spread out and spread out within the chambers 22.23. , thoroughly mixed with the fluid to be treated. Ozone disperses into the fluid to be treated. UV light as it flows along the chamber 22.23 from the inlet end to the outlet end. Irradiation not only affects impurities or other substances in the fluid, but also destroys ozone molecules. By doing so, oxygen atoms are released. The ozone is completely mixed with the fluid and the ozone UV irradiation and liberated oxygen atoms by being destroyed under the action of irradiation act directly and simultaneously on the fluid.

The illumination light in the ultraviolet chamber 22.23 preferably has a wavelength of 2537. Indeed, as mentioned above, as a result of irradiation, oxygen atoms are released and at the same time the action If done, the processing time can be reduced to a few minutes. On the other hand, the same A treatment with various effects is achieved by using ozone irradiation and ultraviolet irradiation independently. The time required to obtain similar results is approximately several times longer if We know it will take 10 times as long.

With respect to the apparatus of FIGS. 1 and 2, the ultraviolet radiation is It has the effect of ensuring that no ozone is present in the treated fluid leaving the mouth end. I mentioned earlier that this is the case. Of course, this is relative to the ozone supplied to the chamber. Can the amount be reliably lower than some percentage of the total mixture in the chamber? and the level of contamination of the fluid to be treated. In any case , by increasing the relative supply of ozone, the outlet of chamber 22.23 is Ensure that free ozone remains in the treated fluid passing through it. You can also do it. This may be a closed system or ozone may be present for other reasons. Useful in some cases. This is because ozone is then destroyed relatively slowly. This is because the other parts of the closed system are then sterilized. Therefore, the above-mentioned device providing a treated fluid containing a predetermined proportion of unreacted ozone; The fluid and/or the fluid that comes into contact after leaving the ultraviolet chamber 22.23 Configuring the surfaces of pipes and other components to remain sterilized or treated Can be done.

In normal operation, ozone is mixed with air in a diffuser, but not with water. Other fluids containing can also be used. For more difficult applications, i.e. If the fluid is highly contaminated or high flow rates are required Oxygen can also be mixed with ozone in a diffuser. Also, Additionally or alternatively, circulating the treated fluid as many times as desired. It may also be passed through an ultraviolet chamber.

Treating malodorous or otherwise contaminated air in a manner similar to that described above. can do.
