PROCESS FOR CONTINUOUSLY DETERMINING THE DUST CONTENT OF FLOWING MEDIA

摘要

The invention relates to a process for the con- tinuous determination of the dust content of flowing media with the isokinetic flow sampling with the separa- tion of the dust or aerosols by cake filtration on a fil- ter and the measurement of the pressure drop at the fil- ter to determine its degree of clogging. To this end the time cycle of the quantity of dust separated on the fil- ter is determined by the measurement of the pressure loss at the filter of an isokinetically operating sampling system. To find the dust load, this quantity of dust is related to the partial quantity of gas extracted iso- kinetically during the period concerned.
