Electrode design is spiral flat tube shape by the utility model, to extend the time of contact of electrode and industrial wastewater, unit
The electrode of length, contact area can increase 15-20%.The water intake mode of electrode uses external-compression type, i.e., by spiral flat tube electrode
Periphery water inlet, central tube water outlet.
The structure of electrode spiral flat tube shape so that when trade effluent flows in electrode by the effect of centrifugal force period surname
Change flow velocity and direction, sewage can be formed when flowing through electrode spiral contact point be detached from electrode wall wake flow, enhance
The turbulivity of waste water itself, it is the contact edge interlayer on tube wall to destroy sewage, improves pollutant in electrode and trade effluent
The contact of matter.
Due to industrial wastewater turbulent flow and helical flow, the sedimentation of dirt in electrode is effectively prevented, in the effect washed away
Under, reduce fouling.
