Abstract

The invention discloses a VOCs on-line monitoring, sampling and pretreating system, comprising a sampling device, a transmission device and a pretreating device, wherein the transmission device is connected with the sampling device and has a full-range equalized heat tracing function, and the pretreating device is used for performing dedusting, drying and constant pressure constant current on sample gas. The sampling device is specially designed for special working conditions such as high temperature, high dust, high moisture, strong corrosion and special gas, a probe is designed with pertinence for ensuring the service life of the probe; three-stage filtration, drying and constant temperature constant current are performed on the sample gas; VOCs after the pretreatment enters external equipment for monitoring VOCs, and VOCs can be accurately monitored and cannot damage the internal elements of the external equipment, thus ensuring the service life of the external equipment.

Description

Technical field [0001] The invention relates to the technical field of VOCs, in particular to a VOCs online monitoring sampling and pretreatment system. Background technique [0002] The purpose of atmospheric monitoring is to conduct regular or continuous monitoring of the main pollutants in the atmospheric environment, to provide a basis for studying the changing laws and development trends of atmospheric quality, and to carry out forecasting and forecasting of atmospheric pollution. With the progress of human civilization, more and more pollutants are released into the atmosphere. Among them, the most serious organic pollutants are VOCs (volatile organic compounds). Therefore, the monitoring of VOCs is an important task of atmospheric monitoring. [0003] VOCs have a wide range of sources, including industrial stationary sources, motor vehicle exhaust emission sources, and daily life sources. Industrial stationary sources are the main emission sources, which have the characteris...
