Background technology
In recent years, ozone (O
3) application more and more extensive, the industry widespread use such as, atmospheric cleaning fresh-keeping in medical science, health, food storing, wastewater treatment and potable water sterilizing.Particularly present filling drinking water is in real-life extensive application, and filling drinking water is to utilize ozone to carry out sterilizing mostly, once the concentration of ozone too much will cause the concentration over-standard of the bromate in filling drinking water, bromate is a kind of carcinogenic substance, by international cancer research institution, has been decided to be " 2B level " potential carcinogenic substance.Some medium-sized and small enterprises are produced in the process of potable water at present, in the situation that guaranteeing Killing Microorganisms In Water, adopt the mode of high-concentrated ozone injection, usually cause the concentration excess of bromate in finished product, cause the defective and quality hidden danger of product, serious will bring infliction of body to consumer.
Detect at present ozone concentration method and roughly can be divided into chemical analysis and the large class of instrumental method two, what chemical analysis was the most frequently used is boric acid potassium iodide absorption spectrophotometry, and this method is bad and will be subject to some restrictions when for detection of filling drinking water to the stability of ozone.The principle of apparatus measures ozone concentration is to adopt chemoluminescence method and ultraviolet radiation absorption process, chemoluminescence method needs adapted ethene gas cylinder, ethene is that combustible is dangerous also inconvenient, what commonly use in the world in recent years is ultraviolet radiation absorption process, its advantage is nontoxic, non-corrosiveness, fast response time, but ultraviolet source is unstable and instrument is also more expensive.
Utility model content
For the defect existing in above-mentioned prior art, the utility model proposes a kind of device ozone concentration being detected based on visible absorption spectrum technology, there is simple, convenient, stable, nontoxic, nonstaining property, fast response time, real-time online measuring is continuous, accuracy rate is high.
Measuring principle of the present utility model is:
When a branch of one-wavelength laser passes through gas medium to be measured, Beer-Lambert law is followed in the variation of its laser intensity:
I wherein
0for initial incident laser intensity, I is the Output of laser intensity after by Ozone Absorption through absorption cell,
absorption coefficient for the corresponding monochromatic wave of ozone.
C is the concentration of ozone, and the length that l is absorption cell utilizes above formula can draw tested ozone concentration.
The technical solution of the utility model is: described a kind of device ozone concentration being detected based on visible absorption spectrum technology, comprising: He-Ne laser instrument, catoptron, beam expanding lens, gas meter, gas piping, ozone bottle, gas absorption cell, convergent lens, detector one, the filling mineral water that needs sterilization, collimation lens, detector two, computing machine; It is a branch of with detector two receptions that the light that He-Ne laser instrument sends is divided into two-beam through catoptron, and the light of a branch of along continuous straight runs is injected gas absorption cell after a beam expanding lens and collimation lens; Ozone bottle is opened rear ozone and from gas piping and after gas meter, is entered gas absorption cell and light mutual effect occurs, and the light after Ozone Absorption penetrates gas absorption cell and assembles and with detector one reception, send into computing machine again and carry out data analysis by overconvergence lens; When the ozone concentration calculating reaches standard, at this moment according to the registration of gas meter, stable the sending in the filling mineral water that needs sterilization of the ozone of this concentration carried out disinfection again.
Described He-Ne laser instrument, the light sending is that wavelength is the ruddiness of 632.8nm.
Described gas absorption cell is that the stainless-steel tube that is 60cm by length is made, and the both sides of gas absorption cell are more than 95% quartz glass sealing with visible light transmissivity.
The utility model changes the concentration that traditional method with ultraviolet source is surveyed ozone, adopt luminous He-Ne laser instrument more stable, that wavelength is single to make light source, although ozone is little to the absorption intensity of this wavelength, but avoided adopting the existing strong ultraviolet ray of ultraviolet source can excite air to produce ozone, affected the error of calculation of final concentration.Have advantages of that simple, convenient, stable, nontoxic, nonstaining property, fast response time, real-time online measuring, accuracy rate are high.
