[0027] In this embodiment, the specific working principle is: when connected with the smoke exhaust pipe 11, first insert the bidirectional butt joint structure into the connecting pipe 1, so that the rear end baffle 3 is located at the rear end opening of the connecting pipe 1, the front end baffle 5 is located at the front end opening of the connecting pipe 1, and the connecting plate 4 is located at the middle of the connecting pipe 1, then the end surface of the smoke exhaust pipe 11 is in contact with the outer surface of the front end baffle 5, then the top joint pipe 2 is combined, the top joint pipe 2 wraps the smoke exhaust pipe 11, and through threaded connection, the top joint pipe 2 is installed on the surface of the connecting pipe 1, the smoke exhaust pipe 11 is pushed into the connecting pipe 1 to the right, then another set of top joint pipes 2 are combined and threaded on the surface of the connecting pipe 1, so that the other set of smoke exhaust pipes 11 are pushed in, at this time, the top joint pipe 2 is rotated to continuously push the smoke exhaust pipe 11 into the connecting pipe 1, so that the two sides of the top stand are concentrated on the connecting plate 4, so that the clamping of the smoke exhaust pipe 11 can be realized, through the elastic force of the extension spring 7, the continuous rotation of the top joint pipe 2 threaded on both sides of the connecting pipe 1 makes the top joint force continuously increase, so as to facilitate the clamping of the smoke exhaust pipe 11, and secondly, when cleaning the smoke exhaust pipe 11, only the top joint pipe 2 needs to be disassembled, which is more convenient. After the flue gas enters the connecting pipe 1 through the smoke exhaust pipe 11, the smoke dust in the flue gas can be filtered in advance through the smoke dust filtering structure, so as to reduce the load of the subsequent gas filtering equipment.

[0028] According to the above, how the top joint pipe 2 further clamps the smoke exhaust pipe 11 can be known by referring to Figure 6 With Figure 7 It can be seen that the top joint pipe 2 is fixed by bolts through the upper and lower two groups of semicircular plates, the outer end surface of the top joint pipe 2 is provided with a top plate 10, the inner side surface of the top plate 10 is provided with a protrusion, the protrusion is in contact with the outer surface of the smoke exhaust pipe 11, when the top joint pipe 2 is rotated by threads to move the top joint pipe 2 to the middle of the connecting pipe 1, so that the protrusion continuously clamps the smoke exhaust pipe 11.

[0029] The smoke dust filtering structure can be known by referring to Figures 7-11 It can be seen that the smoke dust filtering structure includes a circular frame 8 and a blocking plate 9, the circular frame 8 is fixedly installed on the inner surface of the connecting plate 4, the blocking plate 9 is installed on the inner surface of the circular frame 8, and the gas passes through the blocking plate 9 to filter the smoke dust in the gas.

[0030] According to the above, how the blocking plate 9 realizes the filtering of the smoke dust in the flue gas can be known by referring to Figure 10 With Figure 11As can be seen, the baffle plate 9 is composed of multiple sets of triangular plates, and there are gaps between adjacent sets of triangular plates. Furthermore, the baffle plate 9 is composed of upper and lower layers of triangular plates, and the gaps between the upper and lower layers are staggered. The flue gas passes through the lower baffle plate 9, and at this time, the flue gas enters between the upper and lower baffle plates 9 through the gaps between the two sets of baffle plates 9. Then, it diffuses to both sides in an inclined direction, and then diffuses out through the gaps between adjacent upper baffle plates 9. This prolongs the time that the flue gas stays between the two layers 9, allowing the dust in the flue gas to adhere to the baffle plate 9, thereby performing preliminary filtration of the dust in the flue gas and reducing the load on subsequent equipment during gas treatment.
