Abstract

The utility model relates to a high-concentration ozone generator, which comprises a discharge electrode, a high-frequency and high-voltage power supply connected to the discharge electrode, an earth electrode, a film sheet formed into a discharge gap between the discharge electrode and the earth electrode. The utility model is characterized in that the other surface of the earth electrode formed into the discharge gap is provided with a supporting body of a cooling chamber for circulating and cooling the earth electrode by cooling liquid. The discharge gap between the discharge electrode and the earth electrode is 0.1 to 0.5 mm. The utility model has the advantage that because the discharge electrode of the high-concentration ozone generator is not cold, the high-concentration ozone generator is conveniently arranged on a large machine group.

Description

High-concentrated ozone generator-III

The utility model relates to ozone generating-device.

It is different that existing ozone generation device can be described as structure, and size all has, but will seek out the ozone generation device not a duck soup of big ozone generation amount.In order to satisfy industrial application such as water treatment, association with pulp bleaching, often need tens ozone generating-devices to combine and finish.And a series of problems such as that the problem of being brought thus is cost height, volume is big, maintenance is many.

The purpose of this utility model provides the big but little high-concentrated ozone generator of volume of a kind of ozone generation amount.

The purpose of this utility model is achieved in that

A kind of high-concentrated ozone generator: it comprises discharge electrode, is connected in high-frequency and high-voltage power supply, earthing pole on the discharge electrode and the partition that forms discharging gap between discharge electrode and earthing pole, it is characterized in that, said earthing pole is provided with the but supporting mass of the cooling chamber of liquid circulation cooling earthing pole of band cooling at its another side that forms discharging gap, and the discharging gap between said discharge electrode and the earthing pole is 0.1～0.5mm.

Said discharge electrode is to be realized by the rectangular body that alloy aluminum or stainless steel are manufactured, said earthing pole is to be affixed on the said supporting mass that has a cooling chamber by as thin as a wafer high resistivity, the smelting of high dielectric-constant dielectric layer, and the said partition that forms discharging gap between discharge electrode and earthing pole is the partition of high resistivity.

In said discharge electrode is to be realized by the rectangular body that alloy aluminum or stainless steel are manufactured, said earthing pole is to realize directly that by said supporting mass and the corresponding one side of discharge electrode that has cooling chamber the said partition that forms discharging gap between discharge electrode and earthing pole is the partition of high resistivity.

Said dielectric layer thickness is 0.47～1mm.

High resistivity in said discharge extremely area be 100～1600cm ²

Said high resistivity, high dielectric constant dielectric are stupalith.

Its value of said high resistivity is for＞10 ¹⁴Ω cm, its value of said high-k＞9.

Positively effect of the present utility model:

1, because discharge electrode of the present utility model is not cold, so be convenient to be installed on the large-scale unit.

Fig. 1 is a structure iron of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1

Fig. 3 is the I part enlarged view of Fig. 2.

Below in conjunction with accompanying drawing the utility model is described in further details.

In Fig. 1, suction culvert 10 provides water coolant to earthing pole supporting mass 13 (see figure 2)s, 14 cooling chamber 20,22, flows out through outlet pipeline 2.Admission passage 7 is to the discharging gap gas of supplying raw materials, the ozone that is produced under the effect of unstripped gas high-frequency and high-voltage electric field in discharging gap is through outlet pipe 1 output, between admission passage and discharging gap, be provided with the inlet plenum 25 that both are communicated with, between outlet pipe and discharging gap, be provided with the discharge chamber 23 that both are communicated with, inlet plenum and discharge chamber are airtight square structure, and inlet plenum and discharge chamber can guarantee that unstripped gas is at the uniform velocity into and out of in discharging gap.The cable splice 8 of high-frequency and high-voltage power supply 9 through being fixed on the casing 3 is incorporated on the metal level of discharge electrode.

Among Fig. 2, the supporting

mass

13,14 that has cooling chamber 20 is respectively the supporter of two earthing poles, that is to say that present embodiment is two ozone generation devices.The inlet and outlet pipe that provides among cooling chamber 20,22 and Fig. 1 is connected.With position relation between the discharge electrode of two discharging gaps of two the corresponding formation of earthing pole and they as shown in Figure 3.

Discharge electrode 19 is rectangular bodies of being made by stainless steel or alloy aluminum in Fig. 3, each side is being provided with earthing pole 15, and they are separated by two ceramic partitions 16 respectively and form 21, two discharging gaps of two discharging gaps to be 0.1mm wide.The long limit that it is emphasized that the stainless steel rectangular body is parallel with the gas passage of discharging gap, and the stainless steel rectangular body scribbles the aluminium sesquioxide thin layer on the surface that itself and earthing pole form discharging gap, to avoid the discharge electrode galvanic corrosion and to the pollution of ozone gas.Earthing pole 15 and partition 16 are made by stupalith, and its resistivity is 10 ¹⁴Ω cm, specific inductivity are 9.The machining area of discharge electrode is 150mm ²The ozone generation amount of the utility model embodiment is 40g/h, and concentration is 160g/mm ³, production rate is 100g/kwh.Seal gum is with end 24 sealings of discharge electrode and earthing pole.
