Abstract
The invention relates to the technical field of flue gas detection and analysis, and discloses flue gas sampling equipment. In order to solve the problem that blockage cannot be completely removed in the prior art, the technical scheme is provided. The equipment is characterized in that: a built-in filter (7) comprises a filter element (7-2) and an outer cover (7-1); the filter element (7-2) is a transverse cylinder; the outer cover (7-1) is a transverse barrel; the filter element (7-2) is positioned in the outer cover (7-1) and is coaxial with the outer cover (7-1); a circular tube-shaped gap exists between the outer surface circular wall of the filter element (7-2) and the inner side circular wall of a barrel body of the outer cover (7-1); the two ends of the filter element (7-2) are hermetically connected with or adjacent to the barrel body and a barrel cover respectively; and one end of a gas backblowing pipe (4) is communicated with a gas control part (201), while the other end is communicated with the barrel body of the outer cover (7-1) at a gas backblowing hole through a tangent structure. The flue gas sampling equipment has the advantages that: backblowing airflow is rotary or spiral, so the blockage on the filter element can be completely removed and dead angles which cannot be removed do not exist any more.
