ELECTROFILTER Russian patent published in 2008 - IPC B01D35/06 B03C3/40 

FIELD: chemistry, electricity.

SUBSTANCE: electro-filter consists of case, precipitation electrodes made from pipes, and corona electrodes. The corona electrodes consist of alternating sections made in the form of straight sections L₂ and sections L₁, made in the form of a cylindrical spring, and the general length of the corona elements L, the diameter of the spiral d, the distance between the coils of the spiral δ depend on parameters of the cleaned powder-gas flow and are in the ranges: L₁=0.1...0.5 m; L₂=0.1...0.5 m; d=0.1...0.5 D; δ=10...20 d₁, where D - internal diameter of the precipitating electrode, d₁ - diameter of the straight section of the corona electrode.

EFFECT: increase of degree of gas cleaning.
