The invention herewith described refers to the collector electrical filters for purification of gases which consists of the outer metal sheath – the collector (1), which acts as the negative electrode and in the inside of which there is the coating (3) of an insulating material, the corrugated metal inner cylinder (2), which is coated with a thin layer of insulating material of low capacity for polarization of dielectric and acts as a positive electrode. The inner metal cylinder rests on the isolation rings (4, 5) – the electrode supports and the ring (5) through which there is obtained the galvanic connection of the positive electrode with the source of high voltage DC power supply.With connecting to the power source, between the outer cylinder as the negative electrode and the inner cylinder as the positive electrode there will be formed an electric field. In order to maintain a stationary electric field, the inside of the outer cylinder is coated with an insulating coating of adequate dielectric strength.The surface of the positive electrode is coated with a layer of insulating material, which, due to its dielectric properties, prevents neutralisation of negatively charged particles, which under the influence of an electric field, come into contact with the positive electrode resulting in their accumulation on it.The removal of the accumulated particles from the positive electrode is performed by the air under pressure in the process of which the electrodes can be in or out of the collector. Withdrawal of the electrodes from the collector and its return to the original position is provided by the application of the insulating couplings (10) and the movable frame (11).The collector electrical filters can be applied individually for small spaces or within the block collector with more collector electrical filters.
