Abstract
In order to clean a deposit filter having filter elements (4) installed in a suspended manner, first, with the plenum (3) filled with flushing medium, the liquid is discharged completely or partially from the filter chamber by way of an emptying line (7) by opening a ventilating line (6) arranged in the uppermost region of the filter chamber (2), then, by means of a pressure-generating line (8) which is arranged on the plenum and by way of which propellent gas or flushing medium under pressure is conveyed into the plenum, a pressure surge is generated in the plenum and drives the flushing medium through the filter elements, and finally the impurities, together with the liquid, are discharged. Before the pressure surge is exerted, an underpressure can be generated in the filter chamber, in order further to increase the effect. If desired, the filter elements (4) can have an upper gas-impermeable region (5). This method allows a simple and extremely effective cleaning and necessitates only slight changes to the apparatus on deposit filters which are cleaned according to the state of the art.
