Wet elec­tro­sta­tic sep­a­ra­tion: ba­sic prin­ci­ple and de­scrip­tion of the process In­ject­ing re­cir­cu­lat­ing wa­ter causes the crude gas to cool to its sat­u­ra­tion point in­side the crude gas duct. The quenched crude gas then en­ters the fil­ter, where it is uni­formly dis­trib­uted across the en­tire fil­ter cross-sec­tion. In the down­stream gas scrub­ber, dust-type and gaseous or­ganic com­pounds are sep­a­rated. The pre-cleaned gas now flows into the wet elec­tro­sta­tic pre­cip­i­ta­tor. This con­sists of a high-volt­age field with col­lect­ing elec­trodes and cen­trally lo­cated ion­is­ing elec­trodes. The par­ti­cles and aerosols still pre­sent in the gas be­come neg­a­tively charged and move through the elec­tri­cal field to the col­lect­ing sur­face. Pe­ri­odic rins­ing en­sures that the col­lect­ing sur­faces and ion­is­ing elec­trodes re­main clean. The rinse wa­ter re­mains in a closed loop sys­tem that in­cludes an in­ter­nal wa­ter pro­cess­ing unit. Sed­i­men­ta­tion of solids in the wa­ter is made pos­si­ble by spe­cial, built-in patented sed­i­men­ta­tion sur­faces in the wa­ter col­lec­tion con­tainer. This sed­i­men­ta­tion sludge is re­moved via a dis­charge screw and a down­stream de­wa­ter­ing unit. The use of ad­di­tives en­sures a con­sis­tently high wa­ter qual­ity.
