AIR PURIFICATION FILTER Russian patent published in 2007 - IPC B01D46/24 

FIELD: different branches of the national economy; production of the air purification filters.

SUBSTANCE: the invention is pertaining to purification of the compressed air, in particular, from the mists and may be used in different branches of the national economy, predominantly at the large compressor plants with the significant daily consumption of the compressed air. The filter contains: the body with the conical bottom with the hole in its lower part and with the top cover, the perforated metallic cylinder embraced by the wire mesh with the filtering component, the union for the purified air withdrawal equipped with the conical nozzle having the radial grooves, the union for feeding in the air for purification, the unions of input and output of the compressed air filling in the cavity of the jacket. The inlet union is made in the form of the narrowing subsonic nozzle with the curvilinear grooves on its internal surface and having the metal meshes from the side of the atmospheric air inlet. In the body there are the fixed injectors. The bottom is equipped with the condensate remover. The baffle partition with the rigidly fixed porous plate is movably fixed by means of the hinge to the top cover, and by the traction by means of the lever is connected to the condensate remover. This partition forms the chamber between the union of inlet and the plate and also the chamber between the partition and the filtering component. The technical result of the invention is reduction of the power inputs for production of the compressed air by usage of the gas-dynamic pressurization of the intake of the atmospheric air due to design of the air purification filter of the compressor made in the form of the resonator with provision of persistence of the resonance volume in the varying vibration conditions of the compressor plants operation.

EFFECT: the invention ensures reduction of the power inputs for production of the compressed air by usage of the gas-dynamic pressurization of the intake of the atmospheric air and provision of the persistence of the resonance volume in the varying vibration conditions of the compressor plants operation.
