摘要
The subject of the invention is a procedure, a filter module, and an air cleaning device composed of such filter modules for the highly efficient cleaning of air containing small contaminating particles. In the course of the procedure, the principle of adhesion and repelling effect is exploited to capture the contaminating particles in the device composed of an appropriate number of filter modules (1). The air to be cleaned is moved like a quasi-electrodynamic linear engine in the device, so that the mass and/or size of the coagulated particles is increased by the powers of two as necessary while passing through two sequential filter modules (1), up to 220 value. This way, the flow velocity of the fine grains with increased mass is decreasing gradually and they are separated or fall out from the flow space, meaning that particles with a starting size below 1 micrometre, in the nano-range, which are the most harmful to the human body, may also be captured. The essential part of the invention is the filter module (1) that is fitted with electrodes (7), composed of a collector (5) and a separator (6) located at a given distance, which are connected to a positive or negative high voltage (8, 9) and are surrounded by a cover consisting of a base plate, connected to zero potential (10), side plates, and a cover plate. Two electrodes (7) form an electrode pair, and two electrode pairs form a filter module (1), where the electrode pairs are placed so that there is one electrode (7) of the opposite potential installed between two electrodes (7) of the same potential. The solution according to the invention may be used in versatile ways, especially on the field of civil environmental protection, as stand-alone, pre-, or post-filter, such as for cleaning the air and exhaust gas in the chimney of industrial plants, for cleaning polluted urban air, for cleaning, de-germination, and filtering pollen from the air of closed premises, and for military purposes on the field of NBC safety as a pre-filter.
