Rotary charged spraying half-dry method desulfurizing device

The utility model relates to a rotating charged spraying semi-dry process desulphurization unit, which comprises a desulphurization tower. The utility model is characterized in that: a main air inlet pipe extending to the cavity upper part of the tower body is positioned on the middle part of the desulphurization tower, and the side wall of the tower body lower part is provided with an air outlet. A desulfurizer spray head is positioned above the cavity of the desulphurization tower, and a high pressure charged electric appliance is positioned on the neighboring of the desulfurizer spray head to bring induced charge to the tiny dropping of the desulfurizer. The utility model can overcome the disadvantage of that: the alkalescence droppings of the tiny grains fogged by the high speed rotating sprayer are likely to have a collision and coagulate to droppings of big granule, and the spraying powder is not fine of the dry method pressure spray head, and the efficiency of the spray head is too low.
