It is noted that when the blockage factor is between the first predetermined ratio and the second predetermined ratio, the flushing submodule 141 corresponding to the blockage factor is turned off.
It can be understood that, when no industrial camera exists in one preset sub-region in the demister system, the blocking factor corresponding to another preset sub-region in which an industrial camera exists, which has a corresponding relationship with the preset sub-region, is taken as the blocking factor of the two preset sub-regions having the corresponding relationship at the same time, that is, the two preset sub-regions having the corresponding relationship are the target sub-regions of the blocking factor.
