1. a kind of wet electrical dust precipitator, including gas feed diffuser, the first electric field and the second electric field of two series windings, recirculated waterSystem, exit flow distribution grid, gas vent contraction section and housing, it is characterised in that also including mechanical demister, water filtration systemSystem, described circulation include recirculated water collection bucket and the flush box being connected with recirculated water collection bucket, described machineryDemister is arranged between gas feed diffuser and the first electric field, and described mechanical demister both sides are provided with mist eliminator flushingDevice, described mist eliminator flushing device are rinsed to mechanical demister, and the sewage after flushing enters sewage collecting bucket, describedTwo series winding the first electric fields and the second electric field above set electric field flusher, described electric field flusher to first electricityField and the second electric field are rinsed, the recirculated water collection bucket that the water after flushing enters in circulation, described water filtration systemSystem includes the flush box in described circulation, and described flush box includes water tank outfall and water tank circulatesWater outlet, sand filter is set in described flush box, described demister is by a series of herringbone unit parallelRow form, the thickness T of described herringbone unit>

  • 3mm, the arrangement interval S between unit and unit are T<

    S<

    2T, the height of unitSpend H>

    T+S, the width B=2H of unit, the first described electric field are powered by the pulse power, and the second electric field is by traditional high frequency electric sourcePower supply;

    The pulse width 100ns-400ns for the pulse voltage that the described pulse power is provided, repetition rate 20-100Hz, arteries and veinsThe valley for rushing the waveform of voltage is higher than the discharge inception voltage of electric field.
