Abstract

The utility model relates to a double cooled ozone arc chamber which is composed of a high-voltage inner electrode I and an outer low-voltage electrode II. The utility model is characterized in that the high-voltage inner electrode is composed of a steel pipe, a porcelain enamel composite bed arranged on the outer wall of the steel pipe, and a porcelain enamel composite bed arranged on the inner wall of the steel pipe and insulated to inner cooling water and preventing the inner cooling water from corroding a high-voltage discharging body. The low-voltage outer electrode is composed of a steel outer pipe and a steel inner pipe. An air chamber III is formed between the inner and the outer electrodes. Meanwhile, both ends of the steel outer pipe are respectively provided with an air inlet and an ozone guarding outlet. The upper end of the steel outer pipe is provided with a cooling water outlet, and the lower end is provided with a cooling water inlet. When the arc chamber runs, the air or the oxygen passing between the inner and the outer electrodes is uniformly ionized by an electric corona bed to generate the ozone. As the running time is continuous, the arc chamber has advantages of non ascending temperature, high ozone output in unit area, stable running, high efficiency, etc.

Description

Two cooled ozone discharge chambers

Technical field

The utility model patent relates to ozonizer, especially a kind of pair of cooled ozone discharge chamber.

Background technology

Ozonizer is to utilize air or oxygen to make the device of ozone, and this device mainly constitutes by the ozone discharge chamber with for discharge chamber provides the power supply of electric energy.At present, domestic and international existing ozone discharge chamber is divided into board-like discharge chamber and tubular type discharge chamber basically.The tubular type discharge chamber has glass dielectric and non-glass dielectric medium again, by the type of cooling air-cooled and water-cooled is arranged again.The discharge chamber of domestic and international most of ozonizer all adopts the glass discharge medium at present, adopt the outer cooling mode of mostly only employing of water-cooled in the type of cooling, promptly only the low voltage outer electrode of ozonizer is cooled off, and electrode does not cool off in the high pressure, the ozone output of unit surface is lower, along with continuing of working time, ozone output has a declining tendency, and causes the output of whole producer and efficient lower.

Summary of the invention

The purpose of this utility model provides a kind of yield per unit efficient and stability of the power compartment of ozonizer can impelled and is improved, thereby improves two cooled ozone discharge chambers of the performance of whole ozonizer.

Technical solution of the present utility model is: two cooled ozone discharge chambers, the low voltage outer electrode II of its cooling water cavity by electrode I in the high pressure with internal water refrigerating unit with outside having forms, it is characterized in that: electrode in the said high pressure, by steel pipe with make on outer wall of steel pipe enamel composite bed, and make having with the insulation of internal cooling water and can prevent that internal cooling water from constituting electrion body corrosive enamel composite bed on the steel pipe inwall as ozonizer discharge medium layer; Said low voltage outer electrode, constitute by pipe in steel outer tube and the steel, between internal and external electrode, form air chamber III, be respectively equipped with gas inlet and ozone export mouth simultaneously at the two ends of steel outer tube, the upper end that is positioned at the steel outer tube is provided with a cooling water outlet, and the lower end is provided with a coolant intake.

Above-mentioned two cooled ozone discharge chambers, said low-field electrode are that a steel pipe that contains water cavity forms jacket structure for water.

Electrode I and low voltage outer electrode II can singlely match in the above-mentioned two cooled ozone discharge chambers, discharge chamber, also can the interior electrode I of a plurality of high pressure and a low voltage outer electrode II pairing formation honeycomb construction.

The utility model has the advantages that it has adopted the special enamel of non-glass as dielectric substance, and use the two water-cooleds of internal and external electrode as the type of cooling.This ozone discharge chamber scribbles multilayer enamel dielectric substance on the outer wall of high voltage electrode, have higher dielectric constant and compressive strength, and the output of ozone is greatly improved; Simultaneously coat another kind of enamel on inwall, this enamel has good insulativity, and the steel pipe of high voltage electrode and internal cooling water are isolated, and has reduced electric loss, has strengthened the security of producer, has prevented the corrosion of high voltage electrode to steel pipe.Low-field electrode is the water jacket that a steel pipe that contains water cavity forms, and can carry out the cooling of outer electrode easily, makes the homo(io)thermism of ozone discharge chamber, and output improves.The structure and material of whole discharge chamber makes the ozone output of unit surface and stability with respect to general ozone discharge chamber unprecedented raising be arranged all.

Embodiment

In the high pressure structure of electrode as shown in Figure 2, it is to be made of steel pipe 1 and enamel composite bed 2, enamel composite bed 3; Wherein enamel composite bed 2 is arranged on steel pipe 1 outer wall dielectric substance that forms high-k and high compressive strength, another kind is set on the inwall of steel pipe 1 simultaneously has with the insulation of internal cooling water and can prevent that internal cooling water from constituting electrode in the high pressure with three-decker to electrion body corrosive enamel composite bed 3.The inner chamber 13 of steel pipe is full of water coolant when operation, water coolant is isolated by enamel composite bed 3 and steel pipe 1.The one-piece construction of discharge chamber as shown in Figure 1, electrode I is positioned over the inside of low voltage outer electrode II in high pressure shown in Figure 2.Low voltage outer electrode II is by pipe 5 in steel outer tube 4 and the steel and dispose certain accessory device and constitute.Outer tube 4 and interior pipe 5 form water cavity 6, and recirculated cooling water flows into from cooling water outlet 10 from coolant intake 9 and flows out, thereby makes the ozone outer electrode keep constant temp.Form air chamber III between internal and external electrode, air or oxygen 11 enters air chamber from entering the mouth, and through the corona layer that is formed by internal and external electrode complicated electrochemical reaction takes place and forms behind the ozone from 12 derivation.

Electrode I and low voltage outer electrode II can be combined into diversified form and structure in the high pressure, can be single pairing form as shown in Figure 1 structure, electrode II pairing formation honeycomb construction in electrode I and the low pressure as shown in Figure 3, has made things convenient for the manufacturing of big output producer in also can a plurality of high pressure.
