Embodiment

[0044] Such as figure 2 Shown, a kind of concrete realization mode of real-time monitoring system of the present invention is as follows:

[0045] As an exhaust gas sampling unit, the gaseous pollutant sampling unit is installed at the exhaust outlet of the sewage discharge enterprise to sample the flue gas. The flue gas pretreatment unit is used as an exhaust gas pretreatment unit to filter, condense and dehumidify the flue gas samples collected by the gaseous pollutant sampling unit. The flue gas flow controller is set at the output end of the flue gas pretreatment unit to control the flow of the collected flue gas samples, and then transport the flue gas samples to the input end of the VOC detector as the VOC detection unit. The output end of the VOC detector is connected to the data input end of the data acquisition and control system as a data processing unit.

[0046] The exhaust gas parameter measurement unit in this embodiment includes four working branches: the fir...

Abstract

The invention relates to a pollution VOC concentration and total discharge amount real-time monitoring system. The system comprises a exhaust gas sampling unit, an exhaust gas pretreatment unit, a VOC detection unit, an exhaust gas parameter measuring unit, a data processing unit, a back flushing unit, a calibration unit, a communication unit and a central control unit; an output of the exhaust gas sampling unit is connected with the VOC detection unit through the exhaust gas pretreatment unit, both the exhaust gas parameter measuring unit and an output of the VOC detection unit are connected with the data processing unit, an output of the data processing unit is connected with the communication unit, the back flushing unit and the calibration unit, and the communication unit and the central control unit perform data transmission in a wireless mode or a wired mode. The pollution VOC concentration and total discharge amount real-time monitoring system provided by the invention adopts a photoionization detector to detect the concentration and the total amount of particular pollutants discharged by a pollution discharge enterprise, thereby performing real-time monitoring of the concentration and the total discharge amount of VOC. Various compounds including aromatics, ketones, aldehydes, alcohols, ammonia and amines, halogenated hydrocarbons, sulphohydrocarbons, unsaturated hydrocarbons and the like are detected.

Description

technical field [0001] The invention relates to a pollution monitoring system, in particular to a real-time monitoring system for VOC concentration and total emission of pollution sources. Background technique [0002] VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). VOC in the general sense refers to volatile organic compounds, while VOC in the sense of environmental protection refers to a type of active volatile organic compounds, that is, the kind that will cause harm volatile organic compounds. [0003] VOCs, or Volatile Organic Compounds, have a huge impact on human health. When the VOC in the living room reaches a certain concentration, people will have headache, nausea, vomiting, fatigue and other symptoms in a short time, and even convulsions or coma in severe cases. VOCs can damage the liver, kidneys, brain and nervous system, causing serious consequences such as memory loss. [0004] At the same time, VOC is an importan...
