Description

Universal ozone generator

This is practical to relate to a kind of New-type ozone generator, is applicable to space disinfection sterilization, purification, water treatment, occasion such as oxidizing process and green food are fresh-keeping.

At present, common ozonizer mainly is made up of high-voltage power supply and corona discharge two parts both at home and abroad.The economic and technical norms of an ozonizer are also mainly by this two portions decision, and other parts are common general utility appliance, with regard to high-voltage power supply, the single-ended separated exciting low-frequency powers of silicon controlled rectifier that adopt more, very the person directly adopts duplex frequency boostering transformer as high-voltage power supply, it is conspicuous that range of frequency is generally 50-1000, thereby volume is big, and the ozone productive rate is also low; Corona discharge part (producing the ozone part) generally has several structures such as adding dielectric between electron tubes type structure, plank frame and two metal sheets.Above-mentioned several corona discharge assembly, complex process, the cost height not too is suitable for middle-size and small-size ozone generating-device.This paper reference has: the board-like lamination double-sided discharging chamber of the CN85200020U ozonizer of Tsing-Hua University, application number are the high frequency electric source of 87107561 ozone generating-device and small-sized high frequency ozone generator of 92.21449.2 of Zhu Guangguo etc.

The purpose of this utility model provides a kind of New-type ozone generator, and it is little, in light weight to have volume compared with similar products, ozone productive rate height, advantage such as reliable operation and cost are low.Be mainly reflected on two parts of high-voltage power supply and corona discharge.

The purpose of this utility model is achieved in that high-voltage power supply partly adopts semibridge system self-excitation high-frequency oscillating circuits, and range of frequency is that 20K-50K is conspicuous.Select for use three grades of transistors of high frequency of high back-pressure to make switching tube and high-frequency step-up transformer, voltage peak can reach more than the 15K volt; Corona discharge partly selects for use the two-sided copper-coated laminate of epoxy fibreglass cloth to make starting material, by design requirements, erodes away desired electrode shape on its two sides and can make ideal corona discharge sheet.

Owing to take such scheme, after the supplying unit frequency improved, compared with similar products, volume and weight all descended below 50%, and it is simple that part processing takes place corona, and cost is low, long service life.

Below in conjunction with accompanying drawing the utility model is further specified, accompanying drawing is the schematic circuit diagram of the utility model embodiment, and is too simple because of sheet PF takes place, and do not draw instance graph at this.The current rectifying and wave filtering circuit that core of the present utility model is made up of rectification diode D1-D4 and filter capacitor C1-C2, by resistance R 5, capacitor C 3 and two triggering diode D6 form start-up circuit and the triode BG1 and the BG2 of this high-frequency oscillating circuits, high-frequency step-up transformer B1, high-frequency and high-voltage power supply and corona generation sheet FP that sheet FP forms take place, after connecting civil power.Press start button QA, relay J 1 closure, blower fan F and above-mentioned vibrator work, when oxygenous source is surperficial by generation sheet FP, because corona discharge makes the oxygen in the source of the gas be ionized into atomic oxygen, atomic oxygen combines with oxygen and forms ozone, is blown to the place that needs ozone by blower fan.When preset time then, unicircuit 4060 provides just transistor BG3 conducting of a positive pulse, J2 work thereupon disconnects J1, and producer quits work, what it is again emphasized that in the foregoing circuit is, the conducting of BG1 and BG2 with by be by with B1 coupled magnet ring in winding W2 and W3 control automatically, diode D5 guarantees when the BG2 conducting, the charge energy of C3 discharges BG2 conducting again when avoiding the GB1 conducting reliably, BG1 and BG2 do not allow conducting simultaneously, but defeated conductance is logical.

Claims (2)

1, a kind of universal ozone generator is by timing circuit, blower fan, and high-voltage power supply and corona discharge partly constitute, and it is characterized in that: high-voltage power supply adopts transistor high-frequency oscillating circuits and high-frequency step-up transformer; Corona generation sheet adopts two-sided copper-coated laminate.

2, universal ozone generator according to claim 1 is characterized in that: the volts DS behind the direct rectifying and wave-filtering of employing civil power is supplied with by start-up circuit, triode, coupling magnet ring, the semibridge system self-sustained oscillation high frequency electric source that high-frequency step-up transformer is formed.
