GRAINY FILTER USED FOR EXTRACTION OF THE SOOT FROM THE AEROSOL STREAMS Russian patent published in 2008 - IPC B01D46/30 

FIELD: chemical industry; natural gas industry; rubber industry; other industries; production of the grainy filter used for extraction of the soot from the aerosol streams.

SUBSTANCE: the invention is pertaining to the dust catching and can be used for production of the soot used in the capacity of the filling agent in the production of the rubber. The grainy filter includes the sections, each of which is divided by the filtering layer of the soot trapping granules located on the carrying gas-distribution device into the chambers of the dusty and the purified gas and the collectors of the dusty and purified gases. The collectors are connected by means of the distribution valves to the appropriate chambers of the sections. The gas-distribution device is made out of the layer of the coarse-grained carbonic material located on the bearing lattice. At that the bulk density of the layer of the coarse-grained material in 2-3 times exceeds the bulk density of the filtering layer, and the size of its grains in 3-10 times exceeds the size of the grains of the filtering layer. The ratio of the altitude of the gas-distribution layer to the altitude of the filtering layer compounds 0.1-0.3. The technical result of the invention is the uniform distribution of the gas along the volume of the filtering layer at its recuperation and the increased efficiency of the gas purification from the particles of the soot.

EFFECT: the invention ensures the uniform distribution of the gas along the volume of the filtering layer at its recuperation and the increased efficiency of the gas purification from the particles of the soot.
