TH-3000 flue gas online monitoring pre-processing system is suitable for gas detection and analysis in various warm and wet or dusty occasions, and is more suitable for analyzers requiring dryness and cleanliness of gas.
TH-3000 flue gas online monitoring pre-processing system is suitable for gas detection and analysis in various warm and wet or dusty occasions, and is more suitable for analyzers requiring dryness and cleanliness of gas. An automatic blowback system is optional, otherwise it needs regular manual maintenance to clean the dust filter. The whole sampling pipeline has the function of heat preservation and electric thermostat control, which is conducive to removing water vapor and preventing part of the gas from dissolving in condensate to improve the accuracy of detection and analysis, and preventing the sampling pipeline from freezing in winter icing environment. TH-3000 has built-in double-effect compressor water-cooled dehumidification system and 1 meter fine dust filter sampling head (flange installation), with a sampling distance of 70 meters, automatic temperature reduction, automatic drainage and tar filtration. It can control the stability of gas at 4℃ or 5℃ to meet the requirements of humidity and cleanliness of gas for various principles of analytical instruments.
Features:
Outdoor waterproof design, protection, etc. IP66, fast detection and analysis, stable and reliable.
The standard sampling distance is 70 meters, and the gas analysis unit can be built into the chassis, or external.Principle introduction:
Sample gas according to the analyzer can accept the pressure, temperature, humidity, flow, (dust content), and the degree of cleanliness to complete its processing function The following tasks are mainly completed:
1.Sample sampling: the sample gas is extracted from the flue and other environments with a vacuum sampling pump or DC brushless pump.Detection parameters |
