High-purity-ozone generating pipe

Abstract

The invention provides a high-purity-ozone generating pipe which comprises a dielectric substance tube, wherein an outer electrode is coaxially arranged out of the dielectric substance tube and covers the dielectric substance tube, an inner electrode is coaxially arranged in the dielectric substance tube and is covered by the dielectric substance tube. Both ends of the dielectric substance tube, the inner electrode and the outer electrode are fixedly cooperated through generation tube caps. A first tube gap is formed by the inner wall of the outer electrode and the outer wall of the dielectric substance tube. A second tube gap is formed by the outer wall of the inner electrode and the inner wall of the dielectric substance tube. The inner electrode and the generation tube caps are provided with through holes along axial direction of the inner electrode and the generation tube caps. Gas inlet and outlet ports are arranged on the generation tube caps, and the gas inlet and outlet ports run through the first tube gap and the second tube gap. Because of designs of hollow generation tube caps, air circulation in the high-purity-ozone generating pipe can be realized, temperature generated by discharging is reduced. Air circulates between the first tube gap and the second tube gap. The dielectric substance tube is broken through by high voltage applied by the inner electrode and the outer electrode, so that the air between the first tube gap and the second tube gap are ionized. Gases in the inner electrode and the outer electrode are discharged via the gas out let port without generation of other impurities, so that ozone purity can be guaranteed without generation of nitrogen oxides and other harmful gases.

Description

technical field [0001] The invention relates to a high-purity ozone generating tube. Background technique [0002] To artificially generate ozone, the most common technology currently used is to use corona discharge in the gap between the inner and outer tubular electrodes, electrolyze the air flowing through the gap to generate ozone, and use the method of high-voltage discharge to air or oxygen To prepare ozone, it is easy to decompose the generated ozone by the high temperature generated by itself, and the ozone generation efficiency is low. However, the current ozone generation tube adopts a fully enclosed inner electrode coaxial sleeve in the outer electrode, and discharges between the tube gaps. The temperature of the internal electrode is too high, which affects the use effect of the ozone generating tube.

[0003] When air is input into the ozone generating tube, since the inner and outer electrodes are not ventilated, air remains in the gap between the inner and outer electrodes and the dielectric tube, which is prone to generate impurities and affect the purity of ozone. At the same time, nitrogen oxides may be produced due to high-voltage discharge and other harmful gases
