Wherein the external drug adding device can be an acidic solution or an alkaline solution. The prior art has the technical scheme that the two-stage spraying is formed by serially connecting front and rear spray towers, or the three-stage spraying is formed by serially connecting three spray towers, and then the three spray towers are exhausted to a discharge port through a fan. The process can ensure that the waste gas is fully treated, and the waste gas is treated by two or three sections of spray towers. However, after the process waste gas is neutralized by a plurality of sections of spray towers, if the dehumidification effect is poor, a large amount of water vapor or saturated humidity gas can be entrained and discharged through a discharge port, when the external temperature is reduced, the effect of relatively containing the water vapor in the towers is also reduced, and the water vapor caused by the temperature difference is discharged along with a fan and is condensed and atomized with cold air. Causing white smoke of several meters at the discharge opening.
