Device for cleaning exhaust gases from e.g. combustion engine comprises cyclones between inlet and outlet, and measuring device for adjusting gas flow through cyclone

摘要

A device for cleaning exhaust gases comprises a first inlet (3) for exhaust gases, an outlet (5), at least one cyclone (4) between the inlet and outlet, and a measuring device for adjusting the gas flow through the cyclone. The measuring device determines pressure drop over the device, particularly over the cyclone. The device further has a second measuring device for measuring at least one parameter selected from pressure, current velocity, flow rate and temperature.
