The invention relates to a method for obtaining gypsum using a flue-gas desulfurization system (FGD). A gypsum suspension (6), which also contains fine materials such as active carbon particles or residual carbonate particles for example, accumulates in the scrubber (17) of a wet flue gas scrubber. The gypsum-containing suspension (6) is thickened by means of at least one hydrocyclone (1, 1'), and the thickened gypsum suspension (6) is discharged via the underflow (11, 11') of the hydrocyclone (1, 1'). According to the invention, water (5, 5', 15, 15') is fed to the hydrocyclone (1, 1') in addition to the gypsum suspension (6) via a dedicated feed line such that the content of fine material is thus reduced with respect to the suspension volume in the underflow (11, 11').

Hybrid cyclone mist collector

A hybrid cyclone mist collection device having a housing containing an inlet, an outlet and a cyclone body forming a wall extending about a vertical axis. The inlet brings mist-laden air through an airflow straightening area into the cyclone body in a tangential manner, creating a spiral flow path within the cyclone body.

At the bottom of the cyclone body the collected liquid enters an annular drain channel located beneath a vortex deflector plate and an annular shed sheet. A drain connected to the drain channel continuously removes the collected liquid from the housing and returns it to the machine tool station for reuse. The de-misted air exits the outlet and moves on to a central filter housing for final treatment.
