    • A wet electrostatic precipitator (1) comprises an inlet (2) for receiving a gas (4) containing a pollutant, and an outlet (6) for discharging therefrom the gas (8) from which said pollutant has been at least partially removed. Nozzles (24) are operative for purposes of spraying liquid onto at least one first vertical collecting surface (30) of at least one collecting electrode (18). A liquid distributor (42) is provided for purposes of pouring liquid onto at least one second vertical collecting surface (44), said at least one second vertical collecting surface (44) being located on a further collecting electrode (36), with said further collecting electrode (36) being located downstream of said at least one collecting electrode (18). The nozzles (24) are located upstream of the liquid distributor (42), as viewed with reference to the direction of flow of the gas. In a method of cleaning the collecting electrodes (18, 36) an upstream electrode (18) is sprayed with liquid while liquid is poured onto a downstream collecting electrode (36).
    • 湿式静电除尘器(1)包括用于接收含有污染物的气体(4)的入口(2)和用于从其中排出已经至少部分去除了所述污染物的气体(8)的出口(6)。 为了将液体喷射到至少一个收集电极(18)的至少一个第一垂直收集表面(30)的目的,喷嘴(24)是可操作的。 为了将液体注入至少一个第二垂直收集表面(44)的目的而提供液体分配器(42),所述至少一个第二垂直收集表面(44)位于另一收集电极(36)上,所述另一个 收集电极(36)位于所述至少一个收集电极(18)的下游。 喷嘴(24)位于液体分配器(42)的上游,如参照气体的流动方向所示。 在清洗收集电极(18,36)的方法中,在将液体注入下游集电极(36)的同时,喷射上游电极(18)。
