Abstract
The present disclosure provides an apparatus and method for removing particulates from a gas stream. The apparatus includes a ceramic filter, at least one electrode, and at least one conductor. The electrode is located at an end of the filter and produces an atmospheric glow discharge in order to oxidize carbon deposits trapped in the filter. The conductor extends at least partially into the filter and acts as a counter electrode. Through various arrangements of the electrodes and conductors, the present disclosure provides closer connection between the trapped carbon deposits and the electrodes. This improves the regeneration of the filter without increasing the size and/or weight of the apparatus.
