SA-8000 Air Emission Pollution Source Online Monitoring System

The VOC online monitoring system is mainly used for online monitoring and analysis of various atmospheric emission pollution sources and online monitoring of plant boundary concentrations

The main principle is that the sampling unit collects the measured gas on site, the preprocessing unit cools, dehumidifies, and filters dust from the gas, and keeps the temperature and humidity of the measured gas constant within a certain range. The gas detection unit detects and analyzes the gas being transported, displays the concentration of the measured gas in real time on the display screen, and transmits the data signal to the outsidePLC or computer terminals can also be transmitted to cloud servers through wireless GPRS or network, and users can read data from the servers to achieve global network monitoring and analysis. The entire process is automated and does not require human intervention.

The VOC online monitoring system is suitable for gas detection and analysis in low dust, temperature, and humidity environments. If the dust content of the measured gas is high, an automatic blowback system needs to be selected. Otherwise, regular manual maintenance and cleaning of the dust filter are required. The gas pretreatment system is equipped with a built-in high-efficiency compressor water-cooled dehumidification system and a 0.5-meter fine dust filtration sampling head (flange installation), with a sampling distance of 40 meters, automatic cooling, automatic drainage, and tar filtration. For the detection and analysis of gases that are easily soluble in water and outdoor icing environments in winter, insulation and electric heating constant temperature control systems should be selected to prevent the sampling pipeline from icing. If you have high requirements for the dryness and cleanliness of the tested gas, please choose the TH3000 series, which includes insulation and electric tracing constant temperature control system, dual effect compressor water-cooled dehumidification system, and can stabilize the gas at 4 ℃ or 5 ℃.
