Abstract

The invention relates to an integrated optical ozone production volume detection device, a calibration method and a measuring method. The detection device comprises a light source, a first beam splitter, a first reflecting mirror, a second reflecting mirror, a second beam splitter, a charge-coupled device, a data processing system, a reference gas chamber and a sample gas chamber which are arranged on an optical shockproof platform, wherein the first beam splitter divides the light source into two beams of light; one beam of light is irradiated on a reference arm and the other one beam of light is reflected on a sample arm through the first reflecting mirror; the charge-coupled device is arranged on an output light path of the second beam splitter; the data processing system is connected with the output end of the charge-coupled device and is used for processing the received digital signal; the reference gas chamber with fixed volume is arranged on a light path of the reference arm between the first beam splitter and the second reflecting mirror; the sample gas chamber communicated with an ozone generator is arranged on a light path of the sample arm between the first reflecting mirror and the second beam splitter; and the volume of the sample gas chamber changes along with the gas flow speed. The invention integrally realizes the direct measurement of the ozone production volume. The invention replaces separated ozone concentration meter and gas flowmeter, simplifies detection equipment and is suitable for finishing high-precision measurement.

Description

technical field [0001] The invention relates to a device for detecting ozone output by optical method. In particular, it relates to an integrated optical ozone production detection device, a calibration method and a measurement method that can simultaneously detect the ozone concentration and flow generated by an ozone generator, and then calculate the actual ozone production. Background technique [0002] Ozone generators are widely used in water treatment, food preservation, sterilization and other fields. At present, in order to accurately control the ozone output of the ozone generator, it is generally necessary to detect the concentration and flow of ozone, and then calculate the ozone output. In order to detect the concentration and flow of ozone, two different types of equipment are currently required: an ozone concentration meter and a gas flow meter. [0003] The detection of ozone concentration generally adopts chemical analysis method (iodometric method, boric a...

AI Technical Summary

Problems solved by technology

Its measurement accuracy is greatly affected by the processing accuracy and installation error of the flow detection parts, it is difficult to improve the accuracy, the measurement range is narrow, and the long-term use accuracy is difficult to guarantee

Velocity flowmeters are easily affected by pipeline vibration, and it is difficult to maintain calibration characteristics for a long time; fluid physical properties have a greater impact on flow characteristics

Positive displacement flowmeter has complex structure and large volume, and the type, caliber, and working state of the medium to be measured are limited. It is not suitable for high and low temperature occasions, and will generate noise and vibration.

[0005] At present, there is no equipment that can measure the concentration and flow of ozone at the same time. Therefore, multiple instruments are required to detect the concentration of ozone and the flow of gas separately, and then calculate the ozone production. The method is too cumbersome, the operation is inconvenient, and the accuracy needs to be improved.
