Ozone discharging tube, ozone discharging chamber and vertical type ozone generating device

Abstract

The invention relates to an ozone discharging tube, an ozone discharging chamber and a vertical type ozone generating device. The ozone discharging tube comprises a discharging medium tube and a high voltage electrode rod arranged in the discharging medium tube, wherein the discharging medium tube is a titanium quartz glass tube, a chromium layer is coated on the outer wall of the quartz glass tube, and a spring piece is supported between the discharging medium tube and the high voltage electrode rod so as to form a ring-shaped discharging gap; the ozone discharging chamber comprises an upper honeycomb end plate, a lower honeycomb end plate and a plurality of ozone discharging tubes; and the vertical type ozone generating device comprises an air inlet cavity, an air outlet cavity and the ozone discharging chamber. The vertical type ozone generating device has the advantages of high ozone production efficiency, high operation reliability, simple structure, convenience in assembly and low production cost and can be used for manufacturing a large-scale ozone generator; therefore the industrial production of the vertical type ozone generating device can be realized very easily.

Description

technical field [0001] The invention relates to an ozone discharge tube, an ozone discharge chamber and a vertical ozone generating device, and belongs to the technical field of producing ozone by a corona dielectric discharge method. Background technique [0002] As a green and environmentally friendly oxidative bactericide, ozone is currently widely used in water treatment, industrial oxidation, food and pharmaceutical sterilization and disinfection. There are generally two methods for producing ozone, one is the electrolysis method, and the other is the corona discharge method. At present, most industries use the corona method to produce ozone, that is, use the principle of dielectric barrier discharge to ionize oxygen or pure oxygen in the air to produce ozone. As the core component of ozone production, the ozone discharge chamber has been continuously explored and improved at home and abroad. [0003] Ozone is produced by the dielectric barrier discharge method. At pr...

Problems solved by technology

Because enamel and ceramics are sintered on carbon steel metal, due to the difference in thermal expansion coefficient between carbon steel and ceramics or enamel, porcelain explosion is prone to occur, and quality accidents often occur

However, glass has always been troubled by the manufacture of ozone discharge chambers because of its fragility and the uniform size of the discharge gap, which is difficult to control.

The domestic patent (patent number 201020280853.2) applied on July 30, 2010 uses stainless steel mesh, conductive brush, and glass fiber glue to solve the flexible connection. The disadvantage of this solution is that the contact area of ​​the stainless steel mesh is small, which reduces the discharge efficiency. It is complex in technology, difficult in production and processing, and high in cost

[0004] In the existing large-capacity ozone generator, the air intake pipe directly enters the air intake chamber of the ozone generator. Since the generating chamber is composed of multiple ozone generating pipes, the gas volume entering each ozone pipe is uneven, which affects the ozone production.

[0005] The existing domestic large-capacity ozone generator adopts a horizontal structure. Because the ozone discharge rod is placed flat in the ozone tube, the weight of the discharge rod itself makes the gap below the discharge rod smaller and the discharge gap above the horizontal structure larger, resulting in Uniform distribution of the discharge gap affects the amount of ozone generated

In addition, moisture and dust impurities entering the generating room are easy to accumulate in the generating tube and are not easy to discharge, which affects the ozone production and even causes high-voltage breakdown of the discharge tube
