Description

Technical Field

[0001] The invention belongs to the technical field of flue gas sampling, and in particular relates to a flue gas sampler for automatic sampling and collection. Background Art

[0002] Flue gas sampling refers to the process of collecting flue gas samples from industrial emissions or ambient air for analysis of their composition, concentration, and pollutant characteristics, providing data support for environmental monitoring, pollution control, and regulatory compliance. Sampling methods are primarily categorized as direct sampling and dilution sampling. Direct sampling involves extracting flue gas through a probe into a sampling container or analytical instrument. It is suitable for high-temperature, high-humidity, or corrosive gases. Commonly used equipment includes a flue gas sampling gun, condenser, and filter. Dilution sampling involves diluting the flue gas with clean air to reduce its temperature and concentration. It is suitable for collecting respirable particulate matter (PM2.5, PM10) or volatile organic compounds (VOCs). Commonly used equipment includes a dilution tunnel and cyclone separator. Factors such as flue gas temperature, pressure, flow rate, and oxygen content must be considered during sampling to ensure sample representativeness and accuracy. Isokinetic sampling is a key technique, which adjusts the sampling flow rate to match the flue gas flow rate to avoid distorted particle distribution. Condensation and adsorption losses must also be prevented during sampling, typically using heated sampling lines or inert materials. Common analytical items include sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM), and heavy metals. Flue gas sampling is widely used in industrial fields such as thermal power plants, steel mills, and chemical plants, as well as in motor vehicle exhaust detection and indoor air quality assessment. Standardized sampling processes and instrument calibration are key to ensuring data reliability and must comply with national or international standards such as the EPA Method and ISO 12141. With technological advances, online monitoring and portable sampling equipment have become increasingly popular, improving sampling efficiency and real-time performance, and providing a scientific basis for environmental pollution control and emission reduction policymaking.
