1. Method for the control of the purification process in the purification of the filter material of textile rejection filters, preferably of the bag filter type, wherein the contaminated gas of a filter chamber is led in via a raw gas inlet and the filter material installed in the filter chamber, passes under the deposit of dust on the filter material and is drawn away from the filter chamber through a clean gas outlet and the purification is effected in such manner that the filter material is exposed to a compressed air impulse from a purification system, which is controlled by a control system, which senses with measuring elements the pressure drop (Pf ) across the filter material, characterised in that the control system also senses the filter loading (Vf ) which consists of the quotient of the gas flow and the filter area, and forms the quotient of Pf and Vf , i. e. the filter resistance(s), which upon comparison of the filter resistance with a desired value (S0 ) produces a signal for the control of at least one of the parameters which influence the purification effect on the filter material of the purification system. |
