By vertically mounting several suction port partition plates 13 at a distance a that is almost the same as the mutual distance a between the partition plates 9 of the surface plate 7, the suction effect of the central partition space 14 is always maintained on the sides. It can be raised higher than the space. In the figure, the three spaces a at the entrance have the same width as a = a = a, but inside, the relationship between the width of the central space and the width of both sides C is b>
It is possible to significantly enhance the suction effect by making the air volume in the central part larger than that in both sides by configuring it so as to have the relationship C.

Air is blown out along the outer edge of the tip of the air curtain 1.
8, the surrounding outside air is blocked and air from the surroundings is prevented from being drawn in, thereby further enhancing the exhaust smoke absorption effect of the flue.

。Further, as shown in FIGS. 5 and 6, if a water sprinkling pipe 20 having a large number of nozzles 19 is attached to the upper part of the suction port in the hood 12 and a water tank 21 is constructed around the surface plate 7, the water sprinkling pipe can be obtained. By sprinkling water to form a 7-water curtain 22, large-particle dust mixed in the exhaust smoke sucked from the smoke exhaust duct is caused to fall by this curtain 22.1.
At the same time, high-temperature exhaust smoke is cooled by passing through the curtain 22, and damage to the hood 12, duct 11, and dust collector 10 due to high heat can be prevented.

In addition, if a lid 25 for removing dust is attached to a part of the cover 24 so as to be openable and closable, and a wire mesh 26 for preventing dust from passing is provided in a part of the duct 11 covered by the cover 24, the duct can be closed. It is possible to more effectively remove the dust mixed in the exhaust smoke sucked from the exhaust gas 11.
