Abstract

The utility model relates to an ozone generator with air or oxygen as the raw material and generating ozone in a discharge cavity (7) through the discharge of electric corona. The discharge cavity (7) is a closed cavity formed by a bearing body (5) as a cathode and an insulation layer (8) and is provided with an anode (6) inside; the surface of the anode (6) is coated with a conductive ceramic coating layer (14) resisting ozone corrosion to solve the electrode corrosion problem. A semiconductor refrigerator (9) is arranged on the bearing body (5), the refrigeration end of the semiconductor refrigerator (9) is near the discharge cavity (7), and the other end of the semiconductor refrigerator (9) is provided with a heat sink (10) and a fan (11) to assist heat dissipation. Due to that the semiconductor refrigerator is adopted to cool, the utility model has the advantages of simple and compact structure, high efficiency in generating ozone and being capable of being conveniently arranged on a plurality of occasions needing ozone.

Description

A kind of ozonizer

(1), technical field

The utility model relates to a kind of device for preparing ozone, specifically is fit to a kind of ozonizer that use in fields such as tap water purification, disinfection, sewage disposal, fresh-keeping of vegetables.

(2), background technology

Ozone is that raw material produces with corona discharge process mostly with the air or oxygen at present.For the efficient and the work-ing life of improving ozonizer, must cool off with corrosionproof protection discharge electrode and handle.As CN2450205Y, CN2451566Y, the disclosed high concentration ozone generator of CN2451565Y, CN2450204Y, all discharge electrode is provided with water cooling or electrode corrosion-resistant sfgd. in the device of the disclosed preparation ozone water of CN2245056Y.Water cooling is simple, cost is low, but makes whole device volume too fat to move, and is compact inadequately, adds the interference of water-in and water-out pipeline, can't make ozonization plant form the individual devices as household electrical appliance that can arbitrarily move, put.In addition,, reduce the work-ing life of metal electrode, handle so must carry out corrosionproof protection to discharge electrode because the strong oxidizing property of ozone all has the oxidation corrosive nature to metal electrode.

(3), summary of the invention

Need to use in the sterilization equipment of ozone for ozonizer can be arranged on easily, its volume must be small and exquisite, compact, and concerning existing ozonizer, technical problem to be solved is to change the type of cooling.In order to prolong the work-ing life of ozonizer, must be under the prerequisite that does not reduce ozone generator efficiency, the discharge electrode of ozonizer is carried out corrosionproof protection handle.The utility model just is being based on this guiding theory, adopts semiconductor cooler that the discharge electrode of ozonizer is cooled off.And with conductivity ceramics or conductive oxide the discharge electrode surface is handled, to reach discharge electrode is carried out corrosionproof protection, the purpose that increases the service life.The refrigerative technical scheme is: at least one semiconductor cooler is seated on the cathode supporting body that uses as discharge electrode, one side of refrigeration is near discharge cavity, discharge cavity and interior anode thereof are cooled off when discharging, and the opposite side of semiconductor cooler has radiator element and electric fan auxiliary heat dissipation.This advanced type of cooling can be designed ozonizer efficiently simple in structure, compact, easy to use.Processing is also convenient.Volume also greatly reduces.So just ozonizer can be arranged in the sterilization equipment of the use ozone that uses the water cooling inconvenience.To satisfy the needs that all trades and professions are used.Then can organize in parallel the use to the place of a large amount of use ozone, to adapt to the needs of any occasion more.The technical scheme of electrode corrosion-resistant is: what cathode surface applied is the α type aluminium sesquioxide material of high-k.What anode surface applied is NTC series conductivity ceramics or plumbic acid barium series conductivity ceramics, or tindioxide series conductivity ceramics, or tin-doped indium oxide series conductive oxide.

Fig. 1 is the utility model structural representation.

Fig. 2 is A-A cross-sectional view and a local B structure for amplifying synoptic diagram among Fig. 1.

(5), embodiment

In conjunction with the accompanying drawings, the utility model non-limiting examples is described below:

As shown in Figure 1, air or oxygen enters discharge cavity 7 from inlet mouth 1 ozone takes place behind wind box 2, and ozone is through ozone chamber 43 outflows from the air outlet.15 is power supply.

Ozone takes place as shown in Figure 2.Discharge cavity 7 has anode 6 by the airtight cavity that supporting mass 5 and insulation layer 8 as negative electrode are constituted in it, two ends are connected with wind box 2 and ozone chamber 4 respectively.Two semiconductor coolers 9 are arranged on the supporting mass 5 shown in the figure, and a side of its refrigeration is near discharge cavity 7, and opposite side has radiator element 10 and electric fan 11 auxiliary heat dissipations that are fixed on the housing 12.

Local B structure for amplifying illustrates the dipolar corrosion-resistant coating of yin, yang, and discharge cavity inwall (being the cathodic discharge surface) is coated with α type aluminium sesquioxide (Al ₂O ₃) insulating medium layer 13, the coating 14 of anode surface is anti-ozone corrosive conducting ceramic material such as plumbic acid barium series or tindioxide series or NTC series conductivity ceramics or tin-doped indium oxide series conductive oxide.Applying the outstanding advantage that this kind material applies the aluminium sesquioxide insulating material in than other patent scheme at anode surface is: dwindled negative and positive two interpolar arcing distances, the power density when having improved corona discharge has improved the efficient of ozonizer.Negative electrode 5 is made by aluminum alloy materials, and anode 6 is made by materials such as aluminium alloy or stainless steels.Insulation layer 8 is aluminium sesquioxide or polytetrafluoroethylmaterial material.
