Abstract

The equipment that is used for fluids for sterilization comprises ozone chamber 10, and ozone produces therein and mixes in bubbler 13 with the fluid of desire processing.Fluid and ozone mixture are shone with ultraviolet light in chamber 18 again.

Description

Fluidic processing

The present invention relates to fluidic processing.

More particularly, the present invention relates to fluids for sterilization (though being not limited only to this content).Usually fluid is defined as gas or liquid, concerning the object of the invention, also comprise slurry, homogeneous mixture, as rubber cement and effluent etc., method and apparatus of the present invention can handle any mixture can be mobile or common can be with pumping toward the material that handle the chamber, present interested purposes is Food ﹠ Drink processing factory, water perfusion factory, swimming pool, fish farm, aquaria, the secondary effluent is handled or common any pollution or malodorous water or air.

One aspect of the present invention can provide a kind of processing fluidic method, comprises that fluid mixes with ozone, makes mixture through ultraviolet radiation then.

This method also is included in the bubbler fluid and ozone is mixed.

This method can be undertaken by continuity method, after wherein fluid flows through bubbler, flows into the chamber into the irradiation of ultraviolet radiation source.

On the other hand, the invention provides the fluidic equipment of a kind of processing, comprise an ozone chamber, ozone is produced by air therein, a mixing chamber, ozone mixes with the fluid of desire processing after sending into this chamber, and with a ultraviolet chamber that is connected with the mixing chamber that receives the fluid ozone mixture, mixture is placed in and exposes under the ultraviolet radiation in this chamber.

Mixing chamber can comprise that also micro-bubbler is to mix ozone and fluid.

Ozone chamber has independent valve export, can be released in the atmosphere by this outlet ozone.

Fluid treating plant general of the present invention is described in the mode of example with reference to the accompanying drawings, wherein:

Fig. 1 is the sketch of facing of this equipment; With

Fig. 2 is the micro-bubbler cutaway view Amplified image that is used for this equipment.

Referring to accompanying drawing, ozone chamber 10 is connected and comprises an ozone lamp (not shown) with compressed air source, it is converted into ozone with the oxygen in the air in the chamber 10, in order to supply ozone/air mixture, the outlet 11 of chamber 10 or be connected with valve export 12, discharging mixture to atmosphere or to be used for other treatment facility, or be connected, be shown in detail in Fig. 2 with bubbler 13.The setting of water receiver 14 and floss hole 15 is for collecting and remove the condensed steam of accumulation frequently.

Bubbler 13 comprises a porous inert trace diffuser element 16, ozone/air mixture is delivered to fluid that its top and desire handle from wherein flowing through under pressure, supply with fluid that desire handles and 17 send into equipment and flow through bubbler 13 again and enter ultraviolet chamber 18 by entering the mouth with pump.Chamber 18 comprises a mercury vapour lamp (not shown), and when the mixture equipment of flowing to of fluid in this chamber and ozone exported 19, this lamp shone said mixture with ultraviolet light.Fully handled and do not contained ozone by outlet 19 fluid discharged.

Handle fluidic method and described equipment and comprise ozone and ultraviolet processing simultaneously with its simplest form.Ozone is for handling fluid, and particularly sterilization is known, and is same, also is current habitual with the sterilization process of ultraviolet radiation.Yet also nobody proposed before the fluid that utilization ultraviolet radiation desire is handled, and fluid mixes with ozone already, and infuses the end by this embodiment and mix.Therefore, ultraviolet radiation is used for the fluid of " rich ozone ", the result form a kind of with regard to whole processing method more effective and beyond thought technology.

Typical case and gratifying equipment, the fluid that has flows through the flow velocity of equipment between the about 80-500 liter of per minute, and per hour about 15 grams of generation and the ozone amount that uses and total power consumption (be used to generate ozone and produce ultraviolet radiation) are equivalent to two kinds of flow velocitys between about 500-800 watt.The advantage of embodiment of the present invention is that ozone can be destroyed by ultraviolet, and this method is easy to adjust, so that any ozone that residues in the mixture can be destroyed in chamber 18.Only using in the method for ozone, pay particular attention to the ozone that prevents in sterilization or do not become (promptly destroyed) oxygen or oxide in handling and be removed, or handle back keep dissociating (kept free of the fluid) outside the fluid.It is always not possible to this means that ozonization food or other return the fluid (for example fish jar water) that is used for system, thereby need really to be controlled carefully: if not like this, " unexhausted " ozone, owing to chemically react and frequent unhealthful Organic substance and plant, has destruction.So, in fact pass by generally only to use in very low ozone amount or the technical process and must increase step specially to remove any unexhausted ozone.

Although above-mentioned paragraph has been discussed typical equipment, should be realized that the present invention is equally applicable to less or bigger unit, for example have fluid and flow through the unit of the flow velocity of equipment above 10000 liters of per minutes.The corresponding 200-300 gram that per hour increases of ozone-depleting amount.In fact, ozone and ultraviolet irradiating dose depend on purposes.

Claims (6)

1, the fluidic method of a kind of processing after comprising fluid and ozone mixing, makes this mixture through ultraviolet radiation.

2, by the described method of claim 1, comprise that fluid and ozone mix in bubbler.

3, by the described method of claim 2, wherein this method is carried out with continuity method, and fluid flows into the chamber of shining for the ultraviolet radiation source after flowing through bubbler.

4, be used to handle fluidic equipment, comprise an ozone chamber, ozone is produced by air therein, a mixing chamber, ozone enter that the fluid of handling with desire behind this chamber mixes and one with the ultraviolet chamber that is connected by the mixing chamber of receiving the fluid ozone mixture, mixture is placed under the exposure ultraviolet radiation therein.

5, by the described equipment of claim 4, wherein mixing chamber comprises that micro-bubbler is to mix ozone and fluid.

6, by claim 4 or 5 described equipment, wherein ozone chamber has independent valve export, and therefrom this is released in the atmosphere ozone.
