Description

The efficient ozone producer

The utility model relates to a kind of efficient ozone producer that utilizes ozone air, water, other material and object to be carried out sterilization and disinfection.

Ozone is one of present the strongest known oxygenant, has effects such as peculiar sterilization, sterilization, deodorizing.Under normal condition, the less stable of ozone become oxygen through decomposing behind the certain hour in air and in the aqueous solution, and non-secondary pollution, uses so ozone can not resemble other industrial gasses to store with container, and can only now produce existing usefulness.Artificial ozoniferous method has photochemistry, electrochemistry, atomic radiation and corona discharge etc. all kinds of.Along with progress of science and technology, these methods are corresponding all to be developed raising, the advantage benefit is each has something to recommend him, and wherein the corona discharge type ozonizer then is at present lower, the unit ozone output maximum of most widely used general, relative energy consumption, ozone generating-device that share of market is the highest.But compare with Technology Need with the industrial scale of develop rapidly, the corona discharge type ozonizer more and more shows the not high and more high drawback of power consumption of efficient, especially domestic most of products are low because of energy density, concentration of ozone and yielding poorly, cooling heat dissipation is bad and have influence on poor work stability, and power consumption is higher, and volume is big simultaneously, noise is big, and work-ing life is not long.

The purpose of this utility model is the ultimate principle based on corona discharge, and the reliably and again lower efficient ozone producer of power consumption of a kind of energy density height, concentration of ozone and output height, working stability is provided.

Solution of the present utility model is as follows.It has a piped ground electrode made from the metallic conduction material, cold house in the inner formation of piped ground electrode, two ends at ground electrode, have fastening cooling medium inlet tube stub and the heat-eliminating medium outlet pipe connection made with the metallic conduction material that is connected on the ground electrode and all is connected respectively with the interior cold house of ground electrode inside, ground electrode outside between cooling medium inlet tube stub and heat-eliminating medium outlet pipe connection, the intrinsic piped dielectric substance made from insulating material of tight cover, in the dielectric substance outside, have with plain conductor and tightly be wound in piped high voltage electrode in the shape of a spiral, the head end of the used lead of high voltage electrode is suspended on the dielectric substance surface, draw behind the afterbody locator dielectric substance surface of the used lead of high voltage electrode and to the high voltage electrode outside and become the high voltage electrode outlet line, be fixed with one at the outer side of cooling medium inlet tube stub or heat-eliminating medium outlet pipe connection and in fact conduct electricity anastomosing ground electrode outlet line mutually with ground electrode.

The utility model with said structure is when concrete the use, be placed on need to produce ozone carry out disinfection sterilization processing such as (or carry out) deodorizing air volume or have the material or the interior of articles of air volume, the high voltage electrode outlet line is connected with the high-voltage output end that has known or special ozonizer driving circuit now with the ground electrode outlet line, and introduces heat-eliminating medium (water or air) from cooling medium inlet tube stub outer end.Like this, when starting the ozonizer driving circuit after the utility model provides high-frequency high-voltage current, high voltage electrode forms corona discharge to ground electrode, make the rapid ionization of part of oxygen molecule around the high voltage electrode and generate ozone, making the high voltage electrode ambient air produce as long as assurance Working environment employing electric fan etc. carries out artificial water conservancy diversion flows, the ozone that oxygen ionization generates will constantly diffuse to the place that needs ozone on every side, and new oxygen can constantly flow through and carry out ionization, thereby makes ozone generate continuously.In the ozone generation process, flow to next heat-eliminating medium from the cooling medium inlet tube stub, the interior cold house of the ground electrode inside of flowing through takes away the heat that produces in the working process simultaneously, discharges from the exit end of heat-eliminating medium outlet pipe connection at last.

High voltage electrode of the present utility model is wound in the helix structure owing to adopt plain conductor to tighten at dielectric substance, therefore makes to the utlity model has the high efficient performance of generate energy density height, concentration of ozone and output and power consumption is low, the advantage of long working life.When work, the air-flow of participation work takes place to flow along the surface of high voltage electrode, part of oxygen is ionized when generating ozone, its air-flow is also taken away high voltage electrode and dielectric substance surface because of the heat that work produces, add in the tubular metal ground electrode in the cold house heat-eliminating medium to the cooling effect of dielectric substance and high voltage electrode, formed the dual-cooling type cooling structure that the utility model is different from prior art jointly.Because good cooling performance makes whole work system be in an ideal working conditions and environment, thereby can obtain reliable and stable serviceability.Dielectric substance seamlessly tightly is fixed on the tubulose ground electrode, guarantees that not only it has splendid dielectricity and comprehensive physicochemical characteristic, and makes that the utility model volume is little, in light weight, noise is low, the more important thing is the concentration and the output of favourable raising ozone.
