One end of the shell forms a smoke inlet, and the other end of the shell forms a smoke outlet and a sampling port. The support assembly is connected to the inner wall of the shell, and the fan and the filter assembly are arranged on the support assembly. The fan is located in the middle of the shell and the blowing surface of the fan faces the smoke inlet of the shell. The filter assembly is located around the fan, and the drainage assembly is arranged between the fan and the smoke inlet of the shell. The boiler flue gas filter device in the above application will filter and remove impurities from the flue gas during the flue gas discharge process, ensuring good purity and mixing uniformity of the flue gas, solving the problem of large errors in flue gas component detection and impurities easily causing damage to the detection equipment, but it may cause rainwater to flow back into the smoke outlet when it rains, causing interference to subsequent detection and processing.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] For example, see Figure 1-3 A boiler flue gas filtering device comprises a shell 1, a smoke exhaust pipe 2 is fixedly installed on the top of the shell 1, a sampling pipe 3 is fixedly installed on the side of the smoke exhaust pipe 2, and a baffle assembly is arranged inside the smoke exhaust pipe 2;

[0022] The baffle assembly includes a linear motor 7 and a motor guide 8. The motor guide 8 is fixedly installed on the inner wall of the smoke exhaust duct 2. A fixing seat 4 is fixedly installed on the inner wall of the smoke exhaust duct 2. A support rod 5 is fixedly installed on the upper side of the fixing seat 4. A slide seat 6 is fixedly installed on the side of the linear motor 7 away from the motor guide rail 8. The slide seat 6 is slidably connected to the support rod 5. The side of the slide seat 6 is rotatably connected to the support seat 9. A rod three 10 is fixedly installed on the upper side of the support seat 9. The top of the support rod 5 is rotatably connected to a rod one 11. The rod one 11 is rotatably connected to a rod two 12. The lower part of the rod one 11 and the upper part of the support seat 9 are elastically connected by a spring. There are two rods three 10 and they are symmetrically arranged on both sides of the rod two 12. The rod three 10 limits the rotation of the rod two 12 from both sides. The rod two 12 is rotatably connected to the inside of the rod three 10. The tops of the rods one 11 and the two rods 12 are respectively fixedly connected to baffle one 13, Baffle 12 14 and support seat 9 are located directly below motor guide rail 8 and the center axis of support seat 9 and the center axis of motor guide rail 8 are both located on the center line of smoke exhaust duct 2, so that baffle 1 13 and baffle 2 14 are unfolded along the center line of smoke exhaust duct 2, and the width of baffle 1 13 and baffle 2 14 are both larger than the diameter of smoke exhaust duct 2, and the materials of baffle 1 13 and baffle 2 14 are both plastic, which has good corrosion resistance to rainwater. The utility model starts linear motor 7 to drive slide seat 6 to move vertically upward along support rod 5, and with the cooperation of rod 1 11, rod 2 12 and rod 3 10, baffle 1 13 and baffle 2 14 are unfolded on the upper side of smoke exhaust duct 2 to shield rainwater or strong light, thereby preventing rainwater from entering the interior of smoke exhaust duct 2 to cause erosion or strong light from causing local high temperature to smoke exhaust duct 2, thereby greatly extending the service life of smoke exhaust duct 2.

[0023] When in use, in weather conditions where rain or sun protection is required, the linear motor 7 is started. The initial position of the linear motor 7 is at the lowermost end of the motor guide rail 8. After receiving the signal, the linear motor 7 moves vertically upward along the motor guide rail 8, and the linear motor 7 drives the slide 6 to move vertically upward along the support rod 5. When the slide 6 moves, it drives the support seat 9 to move vertically upward. Under the action of gravity, the support seat 9 rotates clockwise in the direction away from the motor guide rail 8, and the angle between the rod 1 11 and the support rod 5 becomes larger. The support seat 9 drives the rod three 10 to rotate. When the rod three 10 rotates, the angle between the rod one 11 and the rod two 12 becomes larger. Due to the elastic force of the spring, the rotation angle of the support seat 9 reaches a certain degree and then stops. At this time, the rod one When the smoke exhaust pipe 2 is not in operation, the linear motor 7 is started in the reverse direction to move it vertically downward along the motor guide rail 8, and the linear motor 7 drives the slide 6 to move vertically downward, so that the support seat 9 rotates counterclockwise, and the support seat 9 drives the rod three 10 to rotate counterclockwise, so that the angle between the rod one 11 and the rod two 12 becomes smaller, and the baffle 13 and the baffle two 14 are folded to avoid affecting the normal use of smoke exhaust.

[0024] For example 2, please refer to Figure 4-5 On the basis of the first embodiment, a scraper 15 is fixedly connected to the side of the linear motor 7, and a sliding seat 17 is fixedly installed on the side of the scraper 15 away from the motor guide rail 8. A fixed rail 16 is fixedly installed on the inner wall of the smoke exhaust pipe 2, and the sliding seat 17 is slidably connected inside the fixed rail 16. The fixed rail 16 can limit the displacement trajectory of the sliding seat 17. The scraper 15 is arranged in an annular structure and the scraper 15 contacts the inner wall of the smoke exhaust pipe 2. Rectangular openings corresponding to the size of the sliding seat 17 are opened on both sides of the fixed rail 16, so that the sliding seat 17 can provide support for the scraper 15. When the linear motor 7 moves vertically up and down along the motor guide rail 8, the utility model drives the scraper 15 to move back and forth up and down along the inner wall of the smoke exhaust pipe 2, and scrapes off the smoke residue on the inner wall of the outlet end of the smoke exhaust pipe 2, which can effectively ensure that the outlet end of the smoke exhaust pipe 2 is relatively clean and reduce the cleaning time of personnel.

[0025] During use, on the basis of Example 1, when the linear motor 7 moves vertically up and down along the motor guide rail 8, it drives the scraper 15 to move back and forth up and down along the inner wall of the smoke exhaust duct 2. At the same time, through the clamping action between the sliding seat 17 and the fixed rail 16, the sliding seat 17 is driven to move back and forth up and down in the fixed rail 16 while the scraper 15 is displaced, so as to avoid the movement trajectory of the scraper 15 from being offset. The scraper 15 scrapes off the smoke residue on the inner wall of the outlet end of the smoke exhaust duct 2, which can effectively ensure that the outlet end of the smoke exhaust duct 2 is relatively clean and reduce the cleaning time of personnel.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
