Abstract

The invention provides an ozone concentration detection device and a method. The ozone concentration detection device is characterized by comprising a long strip shaped air flow pipeline, a first ultraviolet light detector; an ultraviolet light emitter of the first ultraviolet light detector is arranged at one end of the air flow pipeline, and a light receiving sensor of the first ultraviolet light detector is arranged at the other end of the air flow pipeline; the side face of the pipeline is provided with a second ultraviolet light detector and a third ultraviolet light detector; the secondultraviolet light detector and the third ultraviolet light detector are orthogonal to the light direction of the first ultraviolet light detector; the effective length of the air flow pipeline is thefirst distance, and the distance between the second ultraviolet light detector and the third ultraviolet light detector is the second distance; the first distance is less than the second distance. Theozone concentration detection device is simple in structure, fast and effective in detecting method, and can realize the online fast high-precision detection of ozone concentration.

Description

【Technical field】 [0001] The invention relates to the field of gas concentration detection, in particular to an ultraviolet light detection device for ozone gas concentration. 【Background technique】 [0002] Ozone is a slightly odorous gas that can be automatically decomposed into oxygen and has strong oxidizing properties. Utilizing the strong oxidizing properties of ozone, it can sterilize, remove formaldehyde, and remove odors. It is widely used in water treatment, food processing, health care and other fields. In some applications, it is necessary to measure the concentration of ozone gas. [0003] Among the commonly used methods for detecting ozone concentration, the iodometric method is considered to be the most accurate, and the iodometric method is also included in the standard documents for ozone detection in many countries. However, the iodometric method to detect ozone requires many chemical reagents, complicated steps to operate the instrument, and long operati...
