Abstract | The utility model relates to a device for sampling SO3 in flue gas of a coal-fired unit. The device comprises a sampling gun barrel, a depth positioning ring, a heating box, a snakelike collecting pipe, a gas washing bottle, a sampling pump, an ice bath box, a water bath heating box and a temperature controller, a depth positioning ring is arranged on the sampling gun barrel, a sliding device matched with the depth positioning ring is arranged on the sampling gun barrel, and the depth positioning ring can slide to a specific position on the sampling gun barrel; a locking valve is also arranged on the sampling gun barrel and is used for fixing the depth positioning ring on the sampling gun barrel. The device disclosed by the utility model has the beneficial effects that the S-shaped collecting pipe is arranged, so that the SO3 sampling loss is reduced; the two groups of absorption units are connected in series to complement each other to improve the SO3 trapping efficiency; the sampling connection component st |
