Abstract

Фильтрующий элемент относится к фильтрационному оборудованию. Фильтрующий элемент содержит пористую трубчатую подложку (5), фильтрующую мембрану (6), крышку (2) с отверстием (3), днище (1), покрытие и подстилающую плазмохимическую мембрану (4). Пористая трубчатая подложка (5) спечена из полимерных частиц. На торцах пористой трубчатой подложки установлены крышка (2) с отверстием (3) и днище (2). Покрытие выполнено на поверхности полимерных частиц. На внешней поверхности пористой трубчатой подложки (5) нанесена подстилающая плазмохимическая мембрана (4), а на ее поверхности расположена фильтрующая мембрана (6). Предложены следующие частные случаи выполнения фильтрующего элемента. Во-первых, размер полимерных частиц соответствует диапазону от 50 до 180 мкм. Во-вторых, отношение эквивалентных диаметров сквозных пор пористой трубчатой подложки (5) и подстилающей плазмохимической мембраны (4), по меньшей мере, равно 10. В-третьих, отношение эквивалентных диаметров сквозных пор подстилающей плазмохимической (4) и фильтрующей (6) мембран, по меньшей мере, равно 50. В-четвертых, покрытие на полимерных частицах имеет температуру плавления больше 1000°C и выполнено из сорбционно-активных плазменных частиц размером в диапазоне от 0,0035 до 0,0070 мкм или сформировано из их плазмохимических нитридных, оксидных или оксинитридных частиц. В-пятых, покрытие на полимерных частицах имеет температуру плавления не более 1100°C и выполнено из каталитически активных плазменных частиц меди, олова или висмута размером в диапазоне от 0,0055 до 0,0085 мкм или сформировано из их плазмохимических оксидов. В-шестых, полимерные частицы с покрытием из сорбционно-активных и каталитически активных плазмохимических частиц смешаны по массе, по меньшей мере, в соотношении 1:1. Технический результат - повышение тонкости очистки жидкости от механических примесей и эффективности очистки жидкости от растворенных примесей.The filter element refers to filtration equipment. The filter element contains a porous tubular substrate (5), a filtering membrane (6), a cover (2) with a hole (3), a bottom (1), a coating and a underlying plasma-chemical membrane (4). The porous tubular support (5) is sintered from polymer particles. At the ends of the porous tubular substrate there is a lid (2) with an opening (3) and a bottom (2). The coating is made on the surface of polymer particles. An underlying plasmochemical membrane (4) is deposited on the outer surface of the porous tubular substrate (5), and a filter membrane (6) is located on its surface. The following particular cases of filter element execution are proposed. Firstly, the size of the polymer particles corresponds to a range from 50 to 180 microns. Secondly, the ratio of the equivalent diameters of the through pores of the porous tubular substrate (5) and the underlying plasma-chemical membrane (4) is at least equal to 10. Thirdly, the ratio of the equivalent diameters of the through pores of the through pore of the underlying plasma-chemical (4) and filtering (6) membranes at least equal to 50. Fourth, the coating on polymer particles has a melting point greater than 1000 ° C and is made of sorption-active plasma particles with a size in the range from 0.0035 to 0.0070 μm or formed from their plasma-chemical nitride, oxide or ksinitridnyh particles. Fifth, the coating on polymer particles has a melting point of not more than 1100 ° C and is made of catalytically active plasma particles of copper, tin or bismuth in the size range from 0.0055 to 0.0085 μm or formed from their plasma-chemical oxides. Sixth, polymer particles coated with sorption-active and catalytically active plasma-chemical particles are mixed by weight, at least in a ratio of 1: 1. EFFECT: increased fineness of liquid purification from mechanical impurities and efficiency of liquid purification from dissolved impurities.
