Problems solved by technology

When the concentration of trace ions in water vapor is lower than the "warehouse value", a large number of ions will be dissolved into the water vapor sample to be tested, otherwise the ions in water vapor will be partially stored and hidden, all of which affect the accuracy and real-time performance of online water vapor monitoring have a very noticeable impact
[0003] In the prior art, there is no report on the on-line / off-line cleaning technology for the water vapor sampling pipeline. In actual production, the water vapor sampling pipeline with serious pollution is generally dredged or partially replaced, which is difficult to operate and consumes a lot of manpower and material resources. , and cannot overcome the interference of pipeline pollutants on the results of online water vapor monitoring

Abstract

The invention relates to an online cleaning device and method for a water vapor sampling system. The online cleaning device comprises an alkaline cleaning module and / or an acid cleaning module. The alkaline cleaning module comprises an alkaline cleaning tank for preparing an alkaline cleaning solution, an alkali cleaning input pipeline connecting a mother pipe which is to be sampled and provides acleaning water source and the alkaline cleaning tank, an alkali cleaning output pipeline connecting the alkali cleaning tank and a water vapor pipeline to be cleaned, an alkali cleaning input valve arranged on the alkali cleaning input pipeline, an alkali cleaning output valve arranged on the alkali cleaning output pipeline. The acid cleaning module comprises an acid cleaning tank for preparing an acid cleaning solution, an acid cleaning input pipeline connecting a mother pipe which is to be sampled and provides a cleaning water source and the acid cleaning tank, an acid cleaning output pipeline connecting the acid cleaning tank and a water vapor pipeline to be cleaned, an acid cleaning input valve arranged on the acid cleaning input pipeline, an acid cleaning output valve arranged on theacid cleaning output pipeline. The online cleaning device can perform online cleaning on the water vapor pipeline, saves labor and has simple operation, safety, reliability and good cleaning effect.

Description

technical field [0001] The invention relates to the technical field of on-line cleaning equipment for water vapor sampling system pipelines, in particular to an online cleaning device and cleaning method for pipelines and instrument flow pools of an online water vapor quality monitoring system. Background technique [0002] The water vapor sampling system is widely used in industries such as electric power, chemical industry, water affairs, and semiconductor manufacturing for online monitoring of water vapor quality. The pipeline of the water vapor sampling system is easily affected by various pollutants, especially the frequent start and stop of the unit will cause more serious pipeline pollution. The iron corrosion products of the thermal system carried by water vapor, the corrosion products of the sampling pipeline itself, and microbial slime and other pollutants are in the water vapor. Deposits occur in the horizontal pipe of the sampling pipeline or at the elbow with hi...
