Description

Online monitoring instrument for adsorption efficiency of activated carbon Technical Field The utility model belongs to the technical field of environment-friendly monitoring equipment, and particularly relates to an active carbon adsorption efficiency on-line monitoring instrument. Background In the fields of industrial waste gas treatment, indoor air purification and the like, activated carbon adsorption technology is widely used. In the process of adsorbing pollutants such as volatile organic compounds (TVOC) in waste gas, the adsorption capacity of the activated carbon gradually decreases along with the increase of the service time, and when the adsorption reaches saturation, the activated carbon needs to be replaced in time so as to ensure the waste gas treatment effect and the air quality. At present, whether the activated carbon needs to be replaced or not is judged, and most of the methods rely on manual experience or periodic replacement. The problems of strong subjectivity and poor accuracy are judged by means of manual experience, the replacement period cannot be flexibly adjusted by a periodic replacement mode according to actual use conditions, and the problems of waste of active carbon or poor waste gas treatment effect caused by untimely replacement are easily caused.
