After device, for multiple pollutant in wet saturated flue gas after collection removal wet desulphurization.Vertical wet electrical dust precipitator applies more,
Dust collector pole arranges that, due to structure type and arrangement feature, cathod system is pacified using top suspension using hexagonal honeycomb shape
Dress mode.Each electric field cathod system is transferred the load on equipment beam column entirely through four groups of hanging supporting devices, Mei Ge electricity
Field four groups of cathode suspended support meanss of subregion must be installed simultaneously, and load assignment is uniform, it is easy to adjust, and installation accuracy can be protected
Card.Cathod system is connected with high voltage power supply simultaneously, and support meanss must have good insulating properties while load is undertaken,
Cathod system is avoided to cause flashover to discharge with miscellaneous part, influence equipment operational effect and service life, therefore wet-esp
Whether device cathode suspended support structure designs will rationally directly affect equipment operational effect and property indices, be that wet type electricity is removed
One of key technology of dirt device.
