Spiral tubular discharging unit for ozone generator

Abstract

The invention provides a spiral tubular discharging unit for an ozone generator. The discharging unit is formed by interlapping a group of not less than one ground electrode, not less than one insulating layers and not less than one high-voltage electrodes and rolling all parts along an edge until a spiral cylinder is formed, wherein the ground electrodes, insulating layers and high-voltage electrodes are sheet and can be bent; the high-voltage electrodes are separated from the ground electrodes by the insulating layers; a bulge or bulges are formed on one or two surfaces of the insulating layers, on one or two surfaces of each of the ground electrodes and the high-voltage electrodes, or on one or two surfaces of each of the ground electrodes, the high-voltage electrodes and the insulating layers; edges of the insulating layers exceeds the edges of the ground electrodes and the high-voltage electrodes; and discharging gaps are respectively formed between the ground electrodes and the insulating layers as well as between the insulating layers and the high-voltage electrodes. The spiral tubular discharging unit can be applied to various ozone generators, in particular large-scale ozone generators.

Description

Technical field: [0001] The invention belongs to the field of ozone generators and relates to a discharge unit of the ozone generator. technical background: [0002] The stacked discharge unit of the existing large-scale ozone generator generally includes a concentrically installed high-voltage electrode, an insulating tube and a ground electrode, and the sequence from the inside to the outside is the high-voltage electrode, the insulating tube and the ground electrode. Generally, ceramic-coated glass tubes are used as insulating tubes, and stainless steel tubes are used as electrode materials. Dry and purified air or oxygen passes through the discharge gap between the electrodes and the insulating layer. After electrification, ozone is generated in the gap. But its disadvantage is that each discharge unit is a separate set of high-voltage electrodes, insulating tubes and ground electrodes, the discharge gap is large, and the discharge specific surface area of ​​the entire o...

Problems solved by technology

But its disadvantage is that each discharge unit is a separate set of high-voltage electrodes, insulating tubes and ground electrodes, the discharge gap is large, and the discharge specific surface area of ​​the entire ozone generator is small, resulting in a decrease in the ozone production rate and making a single device The output is small, and the large-scale equipment occupies a large area; and the high-voltage electrodes, insulating pipes and ground electrodes are concentric, so the requirements for installation are also high, and the insulating pipes are prone to damage, resulting in high installation and maintenance costs. Stainless steel, glass or ceramics and other materials, so the investment cost of the entire equipment is also high, so it is necessary to overcome the above shortcomings, a large specific surface area, high ozone production rate, small footprint, low investment and maintenance costs, and easy operation Manufactured, easy-to-install discharge unit
