Discharge tube for ozone generator and manufacturing technology thereof

Abstract

The invention discloses a discharge tube for an ozone generator and a manufacturing technology thereof. The discharge tube comprises a grounding electrode and a medium. The grounding electrode is a stainless steel tube, the medium is a glass tube, and the glass tube is arranged on the internal wall of the stainless steel tube. The manufacturing technology comprises the following steps: placing theglass tube in the stainless steel tube, sealing one side of the glass tube and the stainless steel tube by a sealing cover; heating the glass tube by an induction cooker, wherein the heating temperature is 650 DEG C or more, and the glass becomes soft under the effect of heating; blowing nitrogen into the inner side of the glass tube from the other side of the glass tube so as to expand the glassuntil the outer wall of the glass tube is tightly attached on the inner wall of the stainless steel tube; and cooling the stainless steel tube and the glass tube by a forced cold air device, whereinwhen the temperature is reduced to 5 to 60 DEG C, the glass is solidified on the inner wall of the stainless steel tube, and the glass tube and the stainless steel tube are integrated. The discharge tube for an ozone generator has the advantages that the glass tube and the stainless steel tube are integrated, the glass tube is arranged in the stainless steel tube, the glass strength is improved, and the stability and reliability of the discharge tube are both enhanced.

Description

technical field [0001] The invention relates to a discharge tube for an ozone generator and a manufacturing process thereof. Background technique [0002] Ozone is a broad-spectrum high-efficiency disinfectant recognized in the world. It uses air or oxygen as a raw material and uses high-frequency and high-voltage discharge to generate electricity on the air to generate ozone. Ozone has one oxygen atom more than oxygen molecules, and its chemical properties are particularly active. It is a strong oxidizing agent, which can quickly kill bacteria and viruses in air or water and decompose organic matter at a certain concentration. Ozone is decomposed and reduced to oxygen without any toxic residue and will not form secondary pollution. It is known as "the cleanest oxidant and disinfectant". Ozone has the functions of disinfection, sterilization, deodorization, decolorization, etc., and has been widely used in many fields such as water treatment, sewage treatment, chemical indu...

AI Technical Summary

Problems solved by technology

[0004] The existing discharge tubes include glass discharge tubes and enamel discharge tubes. Glass is relatively fragile and is easily damaged in the current electricity environment, causing hidden dangers; enamel is easy to fall off, relatively short life, high maintenance costs, and will also cause equipment security risks
