Description

Technical Field

[0001] The utility model relates to the technical field of chlorine dioxide concentration detection, in particular to a probe which uses a spectrum to measure chlorine dioxide. Background Art

[0002] Chlorine dioxide (ClO2) is an oxidant and disinfectant commonly used in water treatment, wastewater treatment, food processing and disinfection. It has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms without producing toxic byproducts.

[0003] Chinese utility model patent: Publication number CN201752653U, discloses a real-time control device for chlorine dioxide concentration, including a chlorine dioxide concentration meter, a feeding device, a liquid level meter, and a control system. The control system is respectively connected to the chlorine dioxide concentration meter, the feeding device, and the liquid level meter. The feeding device is provided with two material tanks and a valve. The two material tanks are connected to the storage tank through the valve. The chlorine dioxide concentration meter and the liquid level meter are installed in the storage tank.

[0004] In the existing technology, when CN201752653U is used, the concentration of chlorine dioxide is controlled in real time, and the concentration of chlorine dioxide is kept constant during use by adding liquid, thereby delaying the discharge time.

[0005] However, when measuring the concentration of chlorine dioxide, the detection methods currently used mostly adopt liquid chromatography, reagent method or electrochemical method. Among them, the reagent method or electrochemical method may cause pollution to chlorine dioxide when detecting the concentration of chlorine dioxide. Therefore, liquid chromatography has great advantages in detection. However, when detecting by liquid chromatography, the sample needs to be pre-treated and separated by a chromatographic column, which makes the operation more cumbersome and requires regular sampling. For this reason, a probe that uses spectroscopy to measure chlorine dioxide is proposed. By directly inserting the probe into a chlorine dioxide solution, the concentration of the chlorine dioxide solution can be detected, thereby improving the operating efficiency and avoiding the solution from being contaminated. At the same time, the device has a simple structure and is easy to operate when assembled. Utility Model Content
