<p>According to the present invention, there is provided an electrostatic dust precipitator of the wet type, comprising a frame having an inlet for the medium to be cleaned, an outlet for the medium after cleaning and, a fan intermediate the outlet and the outer portion of the frame for causing the medium to flow through the electrostatic dust precipitator. Within the frame are positioned electrically connected alternate positive and negative electrodes, the positive electrodes being string or rod electrodes and the negative electrodes being plate electrodes. A high voltage source is connected to the electrodes and means are provided for causing a flushing fluid to wash down the string electrodes in a direction perpendicular to the flow of the medium being cleaned. A basin is provided at the bottom of the frame for catching the flushing fluid and a pump is provided for pumping the flushing fluid to the means for causing the fluid to wash down the string electrodes. The electrode elements are very easy to clean and maintain, and provide for a simple and economical construction. Various sizes of dust precipitators can be manufactured using only a few sizes of electrode elements.</p> |
