a)The collecting system is subdivided into
electrodes and rapping devices.
The collecting electrodes are profiled metal
sheets, several of which are bundled into an
electrode frame. These electrodes are hanging
in gas direction in the ESP with a certain
distance such that single passages are formed.
Each electrode frame is rapped individually by a
hammer. The rapping hammers of one zone are
fixed onto a shaft which is rotated by a gear
motor and is directly coupled. This suspension
is maintenance-free and resistant to wear.
