The device design benefit can carry out the shutoff to the sampling hole, forms airtight environment in the assurance flue, is favorable to guaranteeing the accuracy of sampling test. But it has the following disadvantages: firstly, the device can be used for an exhaust pipe with a long flange, when the device faces the exhaust pipe with a short flange or without a flange, the device goes deep into the exhaust pipe without support, the fixing effect of a smoke gun cannot be guaranteed, and according to the experience of a sampling site, most of the exhaust pipes without flanges are provided with sampling holes directly on the side wall of the exhaust pipe. Secondly, the vast majority of the fixed pollution source samples are high-temperature waste gas (more than 200 ℃), the material requirements on the plugging block are extremely high, the common material is easy to deform, and the plugging effect is greatly reduced. Therefore, the device has strong selectivity to the exhaust pipe sampling hole and the working condition, and is not suitable for all sampling.
