Bag Filter Shaker Type
The BagFilter Shaker Type dust control unit is a compact, completely self contained fabric filter designed for intermittent duty cleaning, automatically activated when the dust unit is turned off. It is fitted with an electronic controller. This unit is based on fabric areas between 4 mē and 42 mē.
Dust laden gas or air enters through the bottom hopper where the heavy particles fall out by gravity. The gas is then drawn up through the fabric, filtered and subsequently let out of the casing through the damper. The dust is deposited on the inside of the bags. On receipt of an impulse from the time delay (T), pre set during commissioning, the damper (D) in the outlet of one of the chambers closes automatically and the vibrator motor (V) of the same section starts. The dust is shaken off and drops to the bottom hopper where it is collected for removal, normally through a rotary feeder. When the bags are cleaned the damper re-opens and after a predetermined period the next chamber is taken up for cleaning. The cleaning efficiency, alteration to the cleaning programme can be carried by adjusting the time relay. it is also possible to switch off (bypass) the time-relay and operate dampers and vibrator motors manually by push buttons, the pressure drop over the bags can be checked on the manometer fitted on the casing.
Each chamber is automatically taken off the line, one at a time for cleaning as described above. This means that the cleaning process is applied to one chamber at a time when it is isolated from the air/gas flow. Very effective cleaning is achieved by stretching and shaking of the bags together with a simultaneous lateral motion, the shaker beams from which the bags ae suspended are actuated by an eccentric which is driven by a totally enclosed electric motor, the moving parts are supported in a special rubber arrangement and are located on the clean gas side. The shaking gear is robust and needs virtually no maintenance.
The shaking frequency and amplitude is adjustable to a certain extent and, therefore, an optimum condition from the point of view of effective cleaning as well as life of the bags can easily be achieved.
Depending on the applications, a suitable filter fabric is normally chosen. To achieve the best results, the factors which influence the choice of the fabric, for example, the physical properties of the gas and the dust, the temperature during filteration, risk of condensation, required cleaning efficiency and other operating conditions etc. are taken into consideration.
