ELECTRICAL FILTER Russian patent published in 2007 - IPC B03C3/40 

FIELD: natural gas industry; petrochemical industry; other industries; production of the electrical filters used for the gases purification.

SUBSTANCE: the invention is pertaining to the electrical purification of the gases from the dust in various branches of industry and, in particular, in the heat-and-power industry, a chemical industry, building materials industry, metallurgy industry, etc. The electrical filter consists of the body and the depositing electrodes, between which there are the corona-forming electrodes. The electrical filter is made the horizontal. The discharge gap between the corona and depositing electrodes is executed different depending on the height of the electrodes. At that, in the upper part this spacing interval is bigger than in the lower part. The technical result of the invention consists in the increased discharge voltage of the electric filter.

EFFECT: the invention ensures the increased discharge voltage of the electrical filter.
