Abstract: The present invention relates to a maintenance system for electric dust collectors for textile dyeing facilities, in which periodic cleaning of the electric dust collector can be done automatically by a self-operation method of a washing nozzle, thereby providing an effect of increasing maintenance efficiency of the electric dust collectors. To achieve this, the maintenance system for an electric dust collection unit (60) is installed for dust collection in a process of discharging high-temperature hot air generated in a dryer (10) for drying a dyed textile fabric to the atmosphere through an exhaust unit (70). A plurality of dust collectors (61) forming a plate shape are configured in the electric dust collection unit (60) and a washing nozzle (62) for washing is configured on one side of each dust collector (61). The washing nozzle has a structure in which a steam supply unit (62a) supplying high-temperature steam to the washing nozzle (62), a cleaning liquid supply unit (62b) supplying a cleaning liquid, and a purified water supply unit (62c) supplying purified water are connected, thereby performing selective supply and spray toward the dust collector (61) of the steam, the cleaning liquid, and the purified water.
