Here, the air inlet of the demisting space 210 includes a first air inlet 213 and a second air inlet 214; wherein, the first air inlet 213 is located at one end of the bottom plate 211 and is connected to one end close to the gas collecting channel 200, that is, the end above the middle of the gas collecting channel 200; and a second air inlet 214 is provided near the other end of the gas collecting channel 200 and opens into the vicinity of the first air inlet 213 through an air inlet passage 260.

Two air inlets are respectively connected to the two ends of the gas collecting hood 200, so that the water vapor in the whole water slag tank 110 can be sucked into the demisting space 210 more uniformly, and local water vapor caused by uneven suction distribution is prevented from leaking out of the gas collecting hood 200.
Two induced draft fans 250 are installed to the one end that is kept away from first air inlet 213 above the gas collecting channel 200, and the inlet scoop of induced draft fan 250 switches on defogging space 210 for form the negative pressure in defogging space 210, like this, vapor can inhale defogging space 210 by the air inlet, after handling, is discharged from induced draft fan 250 at last.
It should be noted that, a demister is disposed between the first air inlet 213 in the demisting space 210 and the air suction inlet of the induced draft fan 250 along the airflow flowing direction, and the demister is sequentially divided into three stages, namely, a first stage demister, a second stage demister and a third stage demister, and water is removed after the water vapor is subjected to the three stages of treatment, so that a cleaner and drier gas is finally discharged.
