Description
Technical field
The invention belongs to ozonator technical field is and in particular to a kind of ozone generating unit and apply its ozone to send out
Raw device.
Background technology
Ozone has strong oxidizing property due to it, has obtained extensively in industries such as water treatment, sewage disposal, deodorization and discolorations
Application.Conventional ozone preparation method is corona discharge method, and its principle is that natural imitation circle thunder and lightning produces ozoniferous method, passes through
Artificial alternation high voltage electric field produces corona in gas, the free high energy electron dissociation oxygen molecule in corona, so that oxygen is divided
Son becomes atom, and a part of oxygen atom is polymerized to ozone molecule through collision rift.Corona discharge type ozonator is current industry
At most, single machine yield is maximum, the more ripe ozone generating-device of technology for application, wherein again with tube-type ozone generator should
With the most extensive.In whole ozone devices, ozone generating pipe is the heart of ozonator, and the basis of ozone generating pipe is high
Piezoelectricity pole, ground electrode, dielectric substance and discharging gap（Also referred to as air gap）Four parts.Select during ozone generating pipe it is necessary to consider ozone
The dielectric constant size of generator tube dielectric material, reactance voltage breakdown capability and temperature tolerance etc., and the discharge electric field of discharging gap
Intensity, not only relevant with applied voltage peak value, also have with dielectric dielectric constant, the size of discharging gap and dielectric thickness
Close.Research shows, in the case that applied voltage is constant, when discharging gap increases, can form thicker filament-like discharges, and micro-
The distribution density of discharge channel reduces, and the unstability of guiding discharge increases, and therefore should reduce discharging gap as far as possible and electricity is situated between
Matter thickness, increases the dielectric constant of electrolyte dielectric material, is possible to obtain strong discharge electric field intensity.
In existing ozone generating unit, the more commonly used double gap discharge cell structure is by the high-tension electricity of circular tube shaped
Concentrically circle is installed for pole, medium tube and ground electrode, and order is high-field electrode, medium tube and ground electrode from inside to outside, high-field electrode
It is respectively present air gap and medium tube, ground electrode and medium tube between.Common high-field electrode and ground electrode have hollow edged electrode and
Medium tube plated surface conducting film is as two kinds of forms of electrode.The technique effect preferably discharging to realize and radiating, preferably makes
One of air gap try one's best narrow and close to air-gap-free to form single gap discharge cell.Simultaneously because tubule discharging efficiency is high,
The little tube discharge in microgap is significantly promoted in recent years；Accordingly, it would be desirable to the high-field electrode of circular tube shaped or ground electrode are fitted tightly
To form single gap discharge cell on the inwall or outer wall of pipe with small pipe diameter medium tube, its implementation mainly has two kinds：
A kind of is that the external diameter making high-tension electricity pole pipe is tried one's best close to the internal diameter of medium tube, or the internal diameter of ground electrode pipe is as far as possible close
The external diameter of medium tube, the weak point of this scheme is to lead to medium tube and high-field electrode outer surface or ground electrode inner surface
The requirement of precision greatly improve, with high costs, and the less difficulty of processing of caliber is bigger, coaxial mounted difficulty also accordingly increases
Greatly, installation process also easily makes medium tube damaged simultaneously.
Another kind of scheme is the direct inner or outer plated surface conducting film in medium tube, such as Chinese patent 200320131475.1
A kind of disclosed alloy metal film glass ozone generating tube, it includes outer glass pipe, inner glass tube and base, outer glass pipe outer wall
Above and it is plated with alloy metal film on inner glass tube inwall, two pipes are coaxially assembled into base, across two between two alloy metal films
Layer glass simultaneously forms uniform gap, and this patent utilization alloy metal film, as electrode, connects high frequency high on alloy metal film
Voltage source, produces corona discharge in such gap and produces ozone.Although the structure design of alloy metal film is to a certain extent
Improve electric field intensity, but this technical scheme has high demands to the precision process of plated film, particularly less in medium bore
When, such as when bore is less than 1cm, the uniformity of its plated film and the precision of thickness are wayward, and the difficulty of plated film is bigger, at present
The producer of domestic most of plating still cannot meet the requirement to precision, thus increased manufacturing cost and manufacture difficulty.
And the internal plated film of the employing medium tube of prior art is as in the technical scheme of high-field electrode, once the plating as high-field electrode
Film layer is punctured by ozone oxidation or be discharged or easily affects discharge effect during partial exfoliation, or even works the mischief, then must connect
Change together with insulated dielectric tube, maintenance cost is high.Therefore, the ozone generating unit of small size, high yield, high concentration at this stage
Extremely difficult with the production of ozonator, making the unit of ozonator produce ozone amount cannot significantly improve.It constrains little
The production of the ozone discharge cell of medium tube and its ozonator and development, thus, adopt general of coating process at present
Can apply in the ozone discharge cell of Large Diameter Pipeline, single discharge cell volume is big, the volume of the ozonator being made up of it
Accordingly larger.
Therefore, need a kind of small size, structure badly simply, manufacture, easy to maintenance, low cost and easy-to-install ozone occur
Unit and its small size, high yield, the ozonator of high concentration are actually needed to meet.
