Abstract

The invention discloses a continuous monitoring device for flue gas emissions and an automatic verification method for the validity of monitoring data. The device comprises a sampling device, a pretreatment device, an analysis device, a data acquisition device and a verification device, wherein the sampling device is connected with a flue, the pretreatment device is connected with the sampling device, the analysis device is connected with the pretreatment device, the data acquisition device and the verification device are connected with the analysis device, and a verification control device carries out automatic verification on the analysis device regularly and/or when the flue gas measured value monitored by the data acquisition device exceeds an emission limit value. According to the automatic verification method for the validity of monitoring data disclosed by the invention, through carrying out automatic verification on a gas analyzer regularly and/or when the flue gas measured value exceeds an emission limit value, and judging whether the instrument error of the gas analyzer is in an allowed range, valid data is identified, so that the technical problem that existing continuous monitoring devices for flue gas emissions can not evidence the accuracy of measurement data is solved, the evidencing to the accuracy of measurement data is realized, and the accuracy of data measuring of the continuous monitoring device for flue gas emissions is improved.

Description

technical field [0001] The invention relates to the field of flue gas emission monitoring, in particular to a continuous monitoring device for flue gas emission and a method for automatically checking the validity of monitoring data. Background technique [0002] The continuous monitoring device for flue gas emission is used in industrial waste gas emission monitoring to monitor harmful factors that pollute the atmosphere. The common ones are sulfur dioxide, nitrogen oxides, smoke and dust, etc. Purpose of the underlying data. Such as figure 1 , the existing flue gas emission continuous monitoring device is composed of a particulate matter monitoring device, a gaseous pollutant monitoring device, a flue gas emission parameter monitoring device, and a data acquisition device. At present, the mainstream adopts direct sampling, pretreatment (including cold-dry method and hot-wet method), and then enters the analytical instrument for analysis and detection. [0003] At presen...
