As shown in fig. 2-7, the flue guide sleeve 30 according to an embodiment of the present invention includes a sleeve body 100 and guide fins 310.
Wherein, as shown in fig. 2 and 3, a part of the guide fins 310 is disposed in the flue gas channel 110, and another part of the guide fins 310 extends out of the flue gas channel 110 from the flue gas outlet 130, so that the flue gas guided and restrained by the guide fins 310 can rise rapidly in the public flue.
Further, the portion of the guide fin 310 protruding from the smoke passage 110 is disposed flush with the housing 100 in the axial direction of the smoke outlet 130. In other words, the guide fins 310 do not extend rearward beyond the shroud 100. In this way, the guide fins 310 do not occupy the space of the public flue, and the guide fins 310 are prevented from obstructing the smoke emission in the public flue, so that the smoke discharging efficiency of the public flue is further improved.
Of course, the portion of the guide fin 310 extending out of the flue gas channel 110 may extend beyond the housing 100 in the axial direction of the flue gas outlet 130.
Alternatively, as shown in fig. 3, the cross section of the guide fin 310 is arc-shaped, and a tangent to an end (i.e., rear end) of the cross section of the guide fin 310 adjacent to the common flue has a maximum inclination angle α with respect to the horizontal direction.
Of course, the present invention is not limited thereto, and the cross section of the guide fin 310 may be linear, i.e., the guide fin 310 is a plate-like structure.
In some specific examples of the present invention, as shown in fig. 2 and 3, the guide fins 310 are plural and are arranged at intervals in the up-down direction. Specifically, each guide fin 310 extends in the left-right direction, that is, the length direction of the guide fin 310 is oriented in the left-right direction, and a plurality of guide fins 310 are arranged at intervals in the up-down direction. This improves the amount and efficiency of guiding the fluid such as the flue gas by the plurality of guide fins 310.
Alternatively, the plurality of guide fins 310 are disposed at equal intervals in the up-down direction, i.e., the distances between adjacent guide fins 310 are equal, and the plurality of guide fins 310 are uniformly distributed in the up-down direction. Of course, the pitch of the plurality of guide fins 310 may be gradually increased or gradually decreased in the up-down direction.
Preferably, the plurality of guide fins 310 are uniformly distributed in the up-down direction to improve the uniformity of the guide.
Alternatively, the widths of the plurality of guide fins 310 are equal to each other, and the width of the guide fins 310 is a dimension extending substantially in the front-rear direction and along with the shape of the cross section of the guide fins 310. Of course, the width of the plurality of guide fins 310 may be gradually increased or gradually decreased in the up-down direction.
Preferably, the width of the plurality of guide fins 310 is gradually increased in the up-to-down direction to further prevent the downward diffusion of the flue gas discharged to the common tunnel.
In embodiments in which the width of the plurality of guide fins 310 gradually increases or decreases in the up-to-down direction, the edges of the plurality of guide fins 310 adjacent to the flue gas inlet 120 are disposed flush in the axial direction of the flue gas outlet 130.
