Brief description of the drawings
Fig. 1 is the structural representation of photometer embodiment 1 of efficiently measurement concentration of ozone gas.
Fig. 2 is the structural representation of photometer embodiment 2 of efficiently measurement concentration of ozone gas.
Wherein：1st, illuminating source 2, shell 3, optical filter 4, gas outlet 5, change mating plate 6, visible light sensor
7th, gas passage 8, air inlet 9, light transmission piece 10, silicon photocell 11, change light coating are tested.
Embodiment
Fig. 1 is most preferred embodiment of the present utility model, and 1 ~ 2 pair of the utility model is described further below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in figure 1, a kind of photometer of efficiently measurement concentration of ozone gas, includes the shell 2 of column, in shell 2
Offered on axial direction through the inner chamber at its both ends.Illuminating source 1, illuminating source 1 are provided with a port of the inner chamber of shell 2
Irradiation towards inner chamber.Visible light sensor 6 is provided with another port of the inner chamber of shell 2, it is seen that the sense of optical sensor 6
Optical position is towards illuminating source 1.
Optical filter 3 is disposed with along the direction of illumination of illuminating source 1 and become mating plate 5, optical filter in the inner chamber of shell 2
3 and become the outlet inner wall sealing with inner chamber respectively of mating plate 5, and optical filter 3 and become the interval of mating plate 5 and form test gas passage
7, offer air inlet 8 and gas outlet 4 respectively at the radial direction both ends of shell 2, air inlet 8 and gas outlet 4 are simultaneously with testing gas
Passage 7 is connected, and test gas is discharged after air inlet 8 enters test gas passage 7 through gas outlet 4.
Optical filter 3 is chooses the optics of specific wavelength, in this efficiently photometer of measurement concentration of ozone gas, hair
The light that radiant 1 is sent obtains the ultraviolet light that wavelength is 254nm by optical filter 3.The gas for being passed through test gas passage 7 is smelly
Carrier of oxygen, a part can be sponged by ozone gas after by ozone gas by the ultraviolet light that optical filter 3 obtains, not inhaled
Receive partially pass through to be irradiated to after ozone gas becomes on mating plate 5, and the painting of short wavelength UV fluorescent ink is coated with mating plate 5 is become
Layer.Short wavelength UV fluorescent ink be it is a kind of excited by outer light of playing after the material that lights, atomic weak ultraviolet light can be changed
For the high visible ray of intensity, therefore the ultraviolet light that becomes mating plate 5 and can be emitted onto thereon is changed into visible ray, and by visible light sensor
6 monitor, so that visible light sensor 6 sends electric signal.
Because ultraviolet light can be converted to the high visible ray of intensity after the coating by short wavelength UV fluorescent ink, because
This can obtain the light of the ultraviolet light after being absorbed by ozone gas by the visible light sensor 6 of routine by the light intensity of visible ray
By force, so as to judging the concentration of ozone gas.Therefore it is more cheap by price and reliably visible light sensor 6 replaces
Expensive and poor reliability Ultraviolet sensor, production cost is saved, improve the use range of product.
Specific work process and operation principle are as follows：
When needing the concentration to ozone gas to detect, ozone gas is accessed into air inlet 8 first, ozone gas enters
Enter after entering air inlet 8 in test gas passage 7, and exported via gas outlet 4.
Then illuminating source 1 is opened, the light that illuminating source 1 is sent is irradiated on optical filter 3 after entering the inner chamber of shell 2,
And it is changed into the ultraviolet light that wavelength is 254nm after optical filter 3 filters box, ultraviolet light enters after test gas passage 7 necessarily
Absorbed in degree by ozone gas.It is not mapped to by the ultraviolet lighting that ozone gas absorbs on darkening piece 5, then by coated in change
Short wavelength UV fluorescent ink coating on mating plate 5 is converted to visible ray, is finally received by visible light sensor 6, passes through visible ray
The electric signal that sensor 6 exports obtains the light intensity for the ultraviolet light not absorbed by ozone gas, so as to further obtain ozone gas
The concentration of body.
Embodiment 2：
As shown in Fig. 2 the present embodiment and the difference of embodiment 1 are：Mating plate 5 will be become and be replaced by light transmission piece 9, in light transmission piece
9 surface is the coating for being not provided with short wavelength UV fluorescent ink, and light transmission piece 9 is realized using conventional quartz glass.Then will
Visible light sensor 6 replaces with silicon photocell 10, and short wavelength UV fluorescent ink is then applied on the photosurface of silicon photocell 10
Coating formed become light coating 11.
Conventional visible ray silicon photocell absorbing wavelength scope is between 300-1000nm, and peak wavelength is in 700nm.Not by
The ultraviolet light that ozone gas absorbs is producing visible ray of the wavelength into 700nm after becoming light coating 11, exactly visible ray silicon
Photronic absorption peak.After visible ray is absorbed by silicon photocell 10, voltage signal will be converted into by the circuit of routine, led to
The size of measurement voltage signal is crossed, the uptake of ultraviolet light is calculated according to Bill's Lambert law.The course of work of the present embodiment
It is same as Example 1 with operation principle.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
