Deduster and wet scrubber, its general principle and the course of work, are roughly divided into charged, collection and deashing three phases.Wet type
Electrostatic precipitation is identical with structure with dry type static dust general principles, and its main distinction is the difference of purge mode.Dry type is quiet
Electric cleaner is by the way of vibration dust-cleaning, and wet cottrell uses the mode of current cleaning.
Wet cottrell is a kind of efficient deduster, and its purge mode and temperature in use determine that it is efficient special
Point, under normal circumstances, its outlet drain can reach below 10mg/Nm3, or even below 5mg/Nm3.However, existing wet type
The dust removing effects of electrostatic precipitator are undesirable, had no way effective place to go for some phosphorus sulfur materials, while working a period of time
Afterwards, it is necessary to be rinsed to electrode, and all it is that, by being manually sprayed, not only efficiency is low in the prior art, and not
Safety, the top that workman generally requires to climb to deduster carries out operation.
