Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, more particularly to ozone generator and its manufacture method, more
What is related in particular to is a kind of multipipe structure ozone generator for producing ozone by electrion tube reaction with oxygen.
Background technology
Ozone is the allotrope of oxygen, and under normal temperature, normality, normal pressure, the ozone of low concentration is colourless gas, when
When concentration reaches 15%, show light blue.Ozone is water-soluble, solubility ratio of the ozone in water under normal temperature normality normal pressure
Oxygen is high about 13 times, higher than air 25 times.Ozone is a kind of strong oxidizer, can destroy the cell membrane of decomposing bacteria, makes the generation of bacterium
Thank and destroyed with reproductive process, can also be aoxidized, the pollutant in decomposition water, in water process to except odor, decolourize, kill
Bacterium, removal phenol, cyanogen, iron, manganese etc. all have significant effect.But ozone can not be naturally occurring in the occasion needed to use,
It can not collect or store, it is often necessary to be produced in large quantity using its place.For largely producing ozone
Basic skills is to use ozone generator, gas oxygen by high-tension Alternating current discharges region, causes electrostatic electric arc or electricity
Corona, during this process, in the environment of energization, molecular oxygen（O2）Into elemental oxygen, this allows for atom again for alienation
It is combined into ozone（O3）Form.
In domestic sewage treatment device, ozone generator is a critical equipment.In the prior art, by cooling side
Formula divides, and ozone generator has water-cooling type and Wind-cooling type ozone generator, and the practicality such as Application No. 200620039559.6 is new
Type discloses a kind of air-cooling pipe type ozone generator, and the utility model includes stainless steel casing, glass tube, iron powder, aluminum pipe, end cap
Formed Deng device, the hyperfine iron powder of filling in glass tube, glass tube hub is cylindrical, hollow aluminum pipe, and high-voltage connection is consolidated with screw
It is scheduled on aluminum pipe, is drawn by aluminum pipe center, upper and lower end cap is is flexibly connected, and the utility model ozone output is small and service life
It is short.The utility model of Application No. 200820078078.5 discloses a kind of ozone generator, and the utility model includes being assemblied in
Transformer in cabinet and the high-voltage discharge tube to connect with transformer output end, high-voltage discharge tube is by a conductive body and is assemblied in
The glass tube with vacuum composition of built-in tungsten filament electrode in contact tube body, conductive body are provided with air inlet and gas outlet, contact tube
Body and tungsten filament electrode connect transformer output end respectively, when air flows through the annular channel between contact tube body and glass tube with vacuum,
It is ozone that the high pressure that applies between conductive body and tungsten filament electrode, which produces the dioxygen oxidation that electrion is flowed through in air, the practicality
Novel high-pressure discharge tube small volume, especially suitable for the automatic monitor for continuously of air nitrous oxides concentration automonitor, still
Ozone output is very low, can not meet the needs of large amount of sewage processing.Application No. 201520755006.X utility model discloses
A kind of double gap self cooled high-power ozone generator, the utility model are provided with the housing of drum-shaped, are equiped with housing
Interior electrode, external electrode, two piece-root grafting terminals are installed on housing, one layer of glass tube, interior electricity are installed between interior electrode and external electrode
Internal clearance is left between pole and glass tube, external series gap is left between external electrode and glass tube, housing both ends are catchmented equipped with cooling water
Case, housing both ends are respectively arranged with air inlet, gas outlet, and cooling water header tank passes through self priming pump and pipeline and circulating cooling unit
Be connected, circulating cooling unit bottom sets a cooling water tank, although the utility model has double gap, equally can not meet
The needs of large amount of sewage processing.
Application No. 92105968.X disclosure of the invention a kind of multi-tube ozone generator and its manufacture method, the invention exist
When disclosing a kind of multi-tube ozone generator and its manufacture method, a kind of typical ozone generator of the prior art refer to
In, it is indicated that, the typical ozone generator includes multiple elongated cylindrical metal tubes, in the end of metal tube, uses tube sheet
Or end plate supports these metal tubes, in the structure of many prior arts, if end plate includes one piece of common circle with dry hole
Shape metallic plate, this some holes is receiving the end of pipe.During making, the end of pipe is forcibly fed into the perforate of end plate
In, or with welding or similar method the end of pipe is got up with end plate connection.For such structure, each hole of end plate
Between have to leave a certain minimum distance, can be attached to provide enough intensity and support pipe, if
Opening is leaned on too near, then end plate will not have enough intensity to support pipe.In fact, the typical ozone generator is straight
The method by the end of pipe and end plate welding is connect, to change caused by end plate when the end of uncontrollable pipe is welded with end plate
Shape, in such a configuration, more pipes be able to will be restricted by the quantity being mutually combined together, and more pipes
Between do not support, it is difficult to do big.The structure of the ozone generator of Application No. 92105968.X invention, eliminate existing skill
The tube sheet or end plate that are used to support more pipes in the ozone generator of art, are flared out with the end of pipe or are expanded into six
Side shape, with welding or other connected modes, the end for being flared out or expanding of adjacent pipe is welded, every pipe
There are center section and expansion or outward hexagonal end, along the edge being engaged of hexagon, adjacent is outwards opened
The hexagonal end opened, form the nested structure of compact package.But the outward hexagonal end of every pipe occupies
Segment space, the quantity of ozone generating pipe is also restrained in limited spatial dimension, according to the description of the invention, most
Compact form is the multitube generator with 7,19,37,61,91 or more root pipes.Or more root be
One indefinite desired value.Due to also not supported between more pipes, and eliminate for supporting more pipes
Tube sheet or end plate, lose supporting role of the lower perforated plate to more pipes, for ozone generating pipe quantity be more than 1000
Root or more, the invention structure and manufacture method can not meet the requirement that strict control welding is deformed, and can not meet
The demand of large amount of sewage processing.
