Description

Water-cooled ceramic dielectric ozone generating tube

Technical Field

The utility model relates to a corona discharge ozone generation technology. Ozone, as a strong oxidant, has wide applications in various industries. The technology for manufacturing ozone by the corona discharge method is widely applied to the fields of water treatment and environmental protection due to stable operation and reliable operation. The corona discharge technology is classified according to the shapes of basic units of the equipment, and plate-type units and tubular units can be adopted. Tubular ozone generating units are generally called as ozone generating tubes in the industry, and tubular corona discharge ozone generating units are called as ozone generating tubes in the following for short. The ozone generating tube is a basic component for producing a large-scale ozone generator, and the quality of the ozone generating tube directly determines the performance and efficiency of the large-scale ozone generator.

Background

At present, ozone generating tubes are classified in a heat dissipation manner: the ozone generator is divided into a water-cooled ozone generating tube and an air-cooled ozone generating tube; the following types are mainly classified by media types: glass medium, enamel medium, ceramic medium, etc. Regardless of the type of ozone generating channels, it is important to provide a constant operating temperature environment for the ozone generating channels. Therefore, the water-cooled ozone generating tube is widely used with its excellent heat dissipation effect. The utility model relates to a water-cooled ceramic dielectric ozone generating tube.

At present, as shown in fig. 1, the working principle of the commonly used water-cooled ceramic dielectric ozone generating tube is as follows: the outer surface of the metal liner is closely contacted and matched with the inner surface of the ceramic medium for heat transfer; and then the cooling liquid is utilized to take away the heat absorbed by the outer surface of the metal liner, and the flow path of the cooling liquid directly enters the metal liner to absorb and take away the heat generated by ozone discharge. Although the heat dissipation mode can achieve better heat dissipation, the heat dissipation mode has the insurmountable defects: firstly, the temperature difference between the outer surface of the metal liner and the inner surface of the ceramic medium is large, and the heat conduction effect is not ideal; secondly, the processing requirements of the outer surface of the metal liner and the inner surface of the ceramic medium are higher, the manufacturing cost is higher, the yield is low, the processing precision is reduced, and the heat dissipation effect is greatly reduced.

Disclosure of Invention

In order to overcome the defect of the cooling effect of the traditional water-cooled ceramic dielectric ozone generating tube, the utility model provides a novel water-cooled ceramic dielectric ozone generating tube. According to the utility model, the distance between the cooling liquid and the ceramic gap is reduced by changing the path of the cooling liquid, the contact area between the cooling liquid and the ceramic medium is increased, and the heat generated by ozone discharge is more effectively taken away, so that the heat dissipation efficiency is effectively improved, the manufacturing cost is reduced, and a plurality of benefits are brought to batch production.

The technological structure of the utility model comprises: the ceramic cooling device comprises an external cooling liquid outlet, a first ceramic end cover, an internal liquid outlet, a first sealing O-shaped ring, an internal electrode, a ceramic medium, an external electrode, an external positioning screw thread, a second sealing O-shaped ring, an internal liquid inlet and an external cooling liquid inlet which are sequentially connected through screw threads. When the ozone generating pipe works, external cooling liquid flows in from the external inlet of the cooling liquid and flows out from the internal liquid inlet, so that a gap between the inner electrode and the ceramic medium is filled, the filled cooling liquid flows out from the internal outlet of the cooling liquid, and finally flows out from the external outlet of the cooling liquid, and the cooling process is finished.

The heat dissipation principle of the utility model is as follows: after entering the ozone generating tube, the cooling liquid is directly contacted with the ceramic medium, which is different from the traditional water-cooled ceramic medium ozone generating tube which is contacted with the matching surface of the ceramic medium through the metal liner; due to the high-density characteristic of the ceramic dielectric, the insulating property of the ceramic dielectric cannot be reduced, and the smooth proceeding of the ozone discharge process can be completely ensured; under this prerequisite, the seamless combination of coolant liquid and ceramic dielectric has both reduced the distance of stainless steel inner electrode and ceramic dielectric, brings the promotion of heat transfer efficiency by a wide margin again.

It should be noted that the present invention is applicable to a ceramic dielectric ozone generating tube, and is not applicable to other insulating dielectrics. And the end covers at the two ends of the ozone generating tube are made of ceramic materials with the same quality so as to ensure the overall insulating property and stable operation of the ozone generating tube.

The utility model has the beneficial effects that: the temperature difference between the cooling liquid and the ceramic medium is extremely small and is not more than 1 ℃; the processing difficulty of the matching surface of the stainless steel inner electrode and the ceramic dielectric is reduced, and the processing cost is reduced; the distance between the cooling liquid and the ceramic medium is reduced to the minimum, and the ozone production efficiency is improved, so that the performance is improved.
