FIELD: chemistry; technological processes. ^ SUBSTANCE: filtering element consists of adjacent alternating inlet and outlet channels, linked with each other with provision for transmitting fluids through their sidewalls. The element has parts of the sidewalls, which form an intermediate wall between the inlet channels and output channels and have undulation in their cross section, providing for increase in the total volume of inlet channels. The total volume of inlet channels is more than the total volume of outlet channels. The hydraulic diameter of outlet channels ranges from 0.9 to 1.4 mm. The ratio of the total volume of inlet channels to the total volume of outlet channels ranges from 1.15 to 4. The area of the filtration zone ranges from 0.825 to 1.4 m2 per litre of the filtering element. Asymmetry coefficient of the undulation is less than 20%. ^ EFFECT: provision for reduced pressure drop for the whole life span of the filtering element. ^ 21 cl, 5 dwg, 1 tbl |
