< tests >
Hereafter with reference to experimental example, more specifically the present invention is described.Although describe following experiment, when insurmountability scope, suitably can change material therefor, its amount and ratio, process details and treatment scheme etc.Therefore, should according to the explanation of experiment hereinafter described to restricting property of the present invention.
Fig. 8 A presents three kinds of ozone generating apparatus of comparative example 1, comparative example 2 and experimental example 1 operationally, the ozone concn of generation and the relation of time.Experiment shown in Fig. 8 A is all carry out under the condition of gas flow rate 18L/min.
Comparative example 1 is traditional ozone generating apparatus (Ozone Technology, model UV-10) being ultraviolet source with commercially available mercury lamp (power 35W).Because mercury is liquid, must waits for one period of heating, just can be transformed into steam, gas molecule just can release UV-light by electron impact again.Therefore, the ozoniferous speed of the ozone generating apparatus of comparative example 1 comparatively slow (in figure, slope is lower).Comparative example 2 take Excimer lamp as the ozone generating apparatus of ultraviolet source, its structure as Fig. 8 C illustrate.The ozone generating apparatus of the present invention that ozone generating apparatus and Fig. 6 of Fig. 8 C illustrate is similar; its difference is; in the ozone generating apparatus of comparative example 2, lamp tube protective cover is resisted against two end faces of cavity respectively, and inlet mouth and venting port are separately positioned on the sidewall of cavity.After gas passes into from inlet mouth, its mobile route is roughly as shown in the arrow in Fig. 8 C, but, under this design, because ozone generating apparatus does not have air inlet cushioning pocket not to be vented cushioning pocket yet, therefore gas can not be dispersed in cavity equably, can not successfully flow toward venting port, all can form stagnant area R in air inlet place and exhaust place on the contrary, gas is trapped between fluorescent tube and cavity wall.Ozone is very short compound of a kind of transformation period, once be trapped in reaction cavity, shortly can change oxygen into again, energy is expended in rain, and makes that the product of ozone generating apparatus is imitated, production capacity is not good.
Owing to have employed Excimer lamp, and comparative example 1 in comparison, and the ozoniferous speed of ozone generating apparatus of comparative example 2 is fast a lot.But due to the defect in previous designs, the maximum ozone concn of comparative example 1 and 2 is very close.
It is ultraviolet source that experimental example 1 uses with Excimer lamp, and structure design ozone generating apparatus as shown in Figure 6.Difference just as Fig. 6 with Fig. 8 C is only the same with the presence or absence of exhaust cushioning pocket at air inlet cushioning pocket, and the difference of experimental example 1 and comparative example 2 is also only this; The material of each component of ozone generating apparatus, size are all identical substantially.In experimental example 1, the fluorescent tube of Excimer lamp is silica tube, length 140mm, and metal inner electrode penetrates in silica tube, metal net shaped outer electrode ground connection.The Xe gas of 300torr is about in quartzy casing pack.Trigger voltage 1500V(60kHz).What this Excimer lamp produced is exactly the UV-light that wavelength is about 172nm.
As shown in Figure 8 A, the ozone generating apparatus of experimental example 1 is ozoniferous speed very fast (slope is maximum in three curves) not only, finally can stablize the ozone concn that reaches also far above comparative example 1 and comparative example 2, almost reach more than twice.Which demonstrate effect of the present invention.
The productive rate that what Fig. 8 B presented is then comparative example 1, the ozone generating apparatus of comparative example 2 and experimental example 1 shows under different in flow rate condition.With reference to Fig. 8 B, compare with comparative example 1, because comparative example 2 have employed Excimer lamp, it can generate the suitable ozone of concentration with relatively low power, and therefore its productive rate increases.As for the ozone generating apparatus of experimental example 1, due to the structure design (particularly the setting of air inlet cushioning pocket) of its uniqueness, its yield of ozone is especially considerably beyond comparative example 1 and 2.
Fig. 9 A and Fig. 9 B presents the ozone generating apparatus of experimental example 2 and experimental example 3 operationally, the ozone concn of generation and the relation of time.Experiment is all carried out under the condition of gas flow rate 18L/min.Experimental example 2 and experimental example 3 all use the ozone generating apparatus painted as Fig. 6.Difference part is the length L of air inlet cushioning pocket
1different.The L of experimental example 2
16mm.The L of experimental example 3
10.5mm.As can be seen here, as long as air inlet cushioning pocket exists, the effect of buffering, uniform gas distribution can at least be completed when its length is between 0.5mm and 6mm.
In sum, the present invention focuses on the gas flowfield design of ozone generating apparatus, and also can take into account the facility making and assemble, and does not also need too high cost.Design of the present invention makes extraneous gas (such as air or purity oxygen) uniformly across the surface of ultraviolet source, so, the ozone concn produced is quite high, and the ozone generating apparatus solving current use ultraviolet source makes the problems such as complicated, cost is high, cavity easily breaks.
Although in conjunction with above embodiment, the invention has been described, but it is also not used to limit the present invention.Any the technical staff in the technical field, not departing from the prerequisite of the spirit and scope of the present invention, can do a little change and retouching.Therefore the protection domain of subject application is when being as the criterion of defining with appended claim.
