METHOD AND DEVICE FOR DETERMINING PURIFICATION DEGREE AND/OR PERFORMING LEAKAGE TEST

The method involves introducing a test aerosol in a raw gas stream by a feeding unit (16) upstream of a filter element (9). The measurement of a particle or a determination of particle concentration in the flow direction behind the filter element is performed in a clean gas stream. The partial volum...

Zusammenfassung:	The method involves introducing a test aerosol in a raw gas stream by a feeding unit (16) upstream of a filter element (9). The measurement of a particle or a determination of particle concentration in the flow direction behind the filter element is performed in a clean gas stream. The partial volume flows are delivered to a place in the raw gas stream, where a flow cross-section of the raw gas stream is as large as an inlet cross-section of the filter element of the filter arrangement (2). An independent claim is included for a device for determining the degree of separation and for executing a leak test in a filter arrangement for separation of dust and aerosols from a gas volume flow.
