Abstract

The utility model relates to an ozone generator. A filter net is installed in the outer case of an air filter, and the outer case is connected with an air flow passage; the terminal is an air inlet, and a conducting material net is tightly clamped between the inner tube and the outer tube; the two ends of the inner wall in a pipe case are provided with an annular uniform air slot which is communicated with the air inlet; in addition, an air outlet which is separated by 180 DEG from the air inlet is provided; a discharge room is arranged between the pipe case and the outer pipe, and high resistance material is filled between the inner and the outer pipes, and the conducting net which is connected between the inner and the outer pipes is led out of the pipes to be used as the inner electrode; the pipe case which is the outer electrode is fixed by an end cover. The utility model has the advantages of relatively stable structure, no deformation, good heat dissipation, large discharge surface and small volume.

Description

Ozonizer

The utility model relates to a kind of ozonizer, belongs to the technical field of ozone generating-device.

Ozonizer mainly contains three classes, board-like ozonizer, tubular ozone generator and ceramic chip ozonizer, the board-like high equipment of large-scale output of making that is applicable to, the pottery chip is applicable to that air dried environment uses, and tubular type has the advantage of above-mentioned two types concurrently, but existing tubular ozone generator quality is still unstable, and efficient is low, life-span is short again, the metal level of its tubular type glass inwall coating is as interior electrode producer, is easy to come off during cold and hot temperature variation and influences works better, and the inwall of tubular type is equipped with wire, refill with metal-powder, this structure, filling is bad, and manufacturability is very poor, make discharging gap inhomogeneous, the efficient of ozonizer is reduced, and stability is also poor, and it is bad especially to dispel the heat, be unsuitable for long term operation, generally can only work about 15 minutes.

The purpose of this utility model is that a kind of ozonizer will be provided, and it can overcome above-mentioned shortcoming, and this structural volume is little, and machining area is big, and shell is fastening with insulated end cover, has venting practice, and good heat dissipation can be out of shape, and interior electrode can oxidative deformation.

The purpose of this utility model is achieved in that

A kind of ozonizer, it is characterized in that it is combined into one by air filter and producer, air filter has shell (2), in filtering net (1) is housed, shell (1) is connected with a gas channel (3), end has an inlet mouth (5), outer tube (9) and interior pipe (11) grip the net of being made by electro-conductive material (10), shell (7) inwall two ends have all air drains (6) of annular, all air drain (6) communicates with inlet mouth (5), shell (7) has air outlet (13) in addition, constitute a discharge chamber (8) between shell (7) and the outer tube (9), filling is with high-resistance material (13) and be connected with reinforcing conductive mesh (14) between interior pipe (11) and outer tube (9); Fairlead is outer as interior electrode, and shell (7) is as outer electrode, and shell (7) and outer tube (9) are fixing with end cap (4).

Fig. 1 ozonizer synoptic diagram.

Now in conjunction with the accompanying drawings the structure of ozonizer is described in detail:

By Fig. 1, this structure comprises air filter and ozonizer two portions, and air filter has a shell (2), interior dress filtering net (1), and shell (2) is connected with a gas channel (3), and its end has an inlet mouth (5).

The shell of ozonizer (7) is to be made by anti-ozone corrosive metallic conduction material, pipe (11) grips the net of being made by electro-conductive material (10) in dielectric outer tube (9) and dielectric, shell (7) inwall two ends have all air drains (6) of annular, all air drain (6) communicates with inlet mouth (5), shell (7) also has air outlet (13), constitute a discharge chamber (8) between shell (7) and the outer tube (9), between interior pipe (11) and outer tube (9), use the unnecessary gap of high-resistance material (12) filling, and be connected with one and reinforce conductive mesh (14), fairlead is outer as interior electrode, shell (7) and outer tube (9) are fixing with insulated end cover (4), there is ventilation hole (15) at end cap (4) center, shell (7) is as outer electrode, and inlet mouth (5) and air outlet (13) direction differ 180 °, strengthen its cooling effect.

Because the net that interior electrode adopts high conductive material to make, though thereby the producer volume little, machining area is big.Good fastening structure and venting practice make that producer is indeformable when long-term connection work, good heat dissipation, steady quality, and internally electrode adopts hermetically sealed mode, have avoided the oxidation of electrode and sex change etc.Inwall circular trough at shell (7) two ends makes the gas-flow resistance that flows to from inlet mouth (5) little, and can be rapidly evenly in the discharge chamber (8) of circle, inlet mouth (5) differs 180 ° with air outlet (13) direction, both cooled off the inwall of outer tube (9) with shell (7), effectively utilize discharging gap again, improved the productivity of ozone and the homogeneity of ozone content.Hollow air natural convection in interior pipe (11) has effectively improved the heat radiation of interior electrode.

Working process: airflow through airstrainer (1) enter gas channel (3), inlet mouth (5), left end ring all gas advance discharge chamber (8), under shell (7) and interior interelectrode high-frequency and high-voltage effect, produce ozone, extract out by water-jet pump through the equal air drain of right-hand member (6) air outlet (13) then.

Compared with prior art, ozone generator has following advantages:

1, the generator volume is little but machining area is big;

2, fastening with insulated end cover (4), have venting practice, make generator work unlikely Distortion, good heat dissipation, quality are very stable;

3, interior electrode can oxidative deformation;

4, turnover tracheae direction differs 180 °, has not only cooled off outer tube and inner wall of tube shell but also has effectively utilized discharging gap, has improved the homogeneity of ozone output and content;

5, heat radiation is all right.
