TH-2000-C Online Monitoring System for Nitrogen Oxides
Product Description:
The TH-2000-C nitrogen oxide online monitoring system is mainly used in the gas analysis industry. Main detection applications: gas boiler exhaust monitoring, pollution source online monitoring, flue gas emission, desulfurization and denitrification, boiler exhaust, sewage pipeline gas detection and analysis, high-temperature and high-humidity gas detection and analysis, etc.
The main principle is: the sampling unit collects the flue gas or measured gas on site, the pretreatment 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 transported gas, displays the measured gas concentration in real time on the display screen, and transmits data signals externally to terminals such as PLC or computers. It can also be transmitted via wireless GPRS (DTU) or network to local environmental protection bureaus or cloud servers, from which users can read data, enabling global networked monitoring and analysis. The entire process is automated and requires no manual intervention.
The TH-2000-C nitrogen oxide online monitoring system is suitable for gas detection and analysis in environments with low dust, high temperature, and high humidity. If the dust content of the measured gas is high, an automatic back-flushing system or a reserved back-flushing interface for regular compressed air back-flushing is required; otherwise, regular manual maintenance and cleaning of the dust filter are needed. The TH-2000-C gas pretreatment system has a built-in two-stage electronic condensation dehumidification system and a 0.5-meter fine dust filter sampling head (flange installation), with a sampling distance of 40 meters, automatic cooling, automatic drainage, and tar filtration. For gas detection and analysis of gases that are easily soluble in water and for outdoor freezing environments in winter, to prevent freezing of the sampling pipeline, an insulation and electric heat tracing constant temperature control system is required. If high requirements are placed on the dryness and cleanliness of the measured gas, please choose the TH-3000 series, which includes an insulation and electric heat tracing constant temperature control system and a two-stage high-efficiency compressor water-cooled dehumidification system, capable of stably controlling the gas dew point at 4°C or 5°C.
