ION FAN FILTER Russian patent published in 2011 - IPC F24F3/16 

FIELD: instrument making.

SUBSTANCE: ion fan filter comprises a corona-forming negative mesh electrode installed at the inlet, a downstream mesh non-corona-forming receiving electrode, collecting electrodes and a downstream non-corona-forming mesh electrode, at the same the non-corona-forming electrode is installed away from corona-forming needles by distance of 20 mm and is made with cells of 10x10 mm size, even collecting electrodes with length of 130 mm are connected to a negative potential of a power supply source and are made with spikes at one side. Besides, there is an additional non-corona-forming mesh electrode with cells of 10x10 mm size, which is fixed to uneven collecting electrodes and is connected to a positive potential and is installed at distance of 20 mm from corona-forming needles of collecting electrodes, the source of voltage is made for voltage of 10 kV.

EFFECT: increased efficiency of device by volume of treated medium, reduced cost of high-voltage power supply unit.
