Description

TECHNICAL FIELD

[0001] The utility model relates to a smoke dust and flue gas collecting device. BACKGROUND

[0002] The smoke dust and flue gas collecting device is a device for collecting smoke dust and flue gas samples simultaneously. The device generates negative pressure through a power device (such as an air suction pump) to extract mixed gas containing smoke dust and flue gas from a flue or other pollution sources. The device has special separation components inside for the collected mixed gas.

[0003] The smoke dust and flue gas collecting device also has a filtering device inside for further separating smoke dust and flue gas. For example, glass fiber filter paper or a filter barrel is used to filter smoke dust. These filter papers or filter barrels can effectively intercept tiny smoke dust particles while allowing flue gas to pass through. Then, different collection containers are used to collect smoke dust and purified flue gas, respectively, for subsequent component analysis and other operations.
