The DOAS-3000 online differential ultraviolet spectrometer is mainly used in the gas analysis industry. The main detection occasions: flue gas emission, desulfurization and denitrification, boiler exhaust, VOCs exhaust, sewage pipeline gas detection and analysis, etc. The main principle is: the sampling unit collects the flue gas or the measured gas on the spot, and the pretreatment unit filters the dust, high temperature cooling, electric heating and heat preservation, two-stage high-efficiency dehumidification, and the temperature and humidity of the measured gas, and dust particles. Control in a certain range to achieve the cleanliness required by the analyzer, and then send it to the gas analysis unit for detection and analysis. The measured gas concentration is displayed on the display screen in real time, and the data signal is transmitted to the PLC or computer and other terminals. It can be transmitted to the cloud server via wireless GPRS or network, and the user can read the data from the server to realize global network monitoring and analysis. The whole process is automated and does not require human intervention. DOAS-3000 online differential ultraviolet spectrometer is used in various high temperature, high humidity or high dust occasions. It can be equipped with an automatic back blow system, otherwise manual maintenance and cleaning of the dust filter is required. The entire sampling pipeline has the function of electric heating and heat preservation, which is beneficial to remove water vapor and prevent part of the gas from dissolving in the condensed water to improve the accuracy of detection and analysis.
