METHOD AND DEVICE FOR MODERNIZATION OF ELECTROFILTER Russian patent published in 2017 - IPC B01D50/00 B03C3/155 B01D36/02 

FIELD: technological processes.

SUBSTANCE: method for modernization of an electrofilter consisting of several fields is carried out by installing horizontal rows of filter elements facing the gas flow, a regeneration system with distributing pipes installed horizontally, and a clean gas chamber with a hose plate installed vertically, in the last field of electrofilter. In this case, the switching off filter elements from gas flow for regeneration is carried out by groups of horizontal rows of filter elements. Disconnection of groups of elements is carried out alternately from top to bottom, and regeneration of the rows in each disconnected group is carried out alternately from the bottom up. The device for the modernization of electrofilter includes the installation of a part of the last field of a hose plate with horizontal rows of filter elements, placed edges upstream to gas, a regeneration system with distributing pipes installed horizontally, and clean gas chambers. Wherein, the clean gas chamber along the height of the hose plate and the number of groups of horizontal rows of filter elements is divided into sections with a separate gas flow outlet.

EFFECT: modernization of existing electrostatic precipitators in the same dimensions of the body of the device with simultaneous increase in efficiency and durability of the filter part of the electrofilter.
