Statement of the problem. Currently, there is no methodology for calculating the degree of clogging of a multilayer filter cartridge taking into account the prevention of deposition of mechanical impurities in the gap between the coarse and fine filter cylindrical filter cartridges. In this regard, the development of such a technique is an urgent task. Results. In this paper, we propose a calculation method for determining the average integral degree of clogging of multilayer cylindrical filter cartridges with mechanical impurities and pressure loss on them which take into account the prevention of sedimentation of mechanical impurities in the gap between the coarse and fine filter cartridges.Conclusions. The results obtained make it possible to determine the pressure loss and the average integral degree of clogging of the multilayer filter cartridge depending on the decrease in the living cross-section of all filter meshes in the process of clogging and to prevent the deposition of solids in the gap between the coarse and fine filter cartridges.

Состояние проблемы. В настоящее время отсутствует методика расчета степени засорения многослойного фильтрующего картриджа, учитывающая недопущение осаждения механических примесей в зазоре между цилиндрическими фильтрующими картриджами грубой и тонкой очистки. В этой связи разработка такой методики является актуальной задачей. Результаты. В данной работе предложена методика расчета по определению среднеинтегральной степени засорения многослойных цилиндрических фильтрующих картриджей механическими примесями и потери давления на них, которые учитывают недопущение осаждения механических примесей в зазоре между цилиндрическими фильтрующими картриджами грубой и тонкой очистки. Выводы. Полученные результаты позволяют определить величины потерь давления и среднеинтегральной степени засорения многослойного фильтрующего картриджа в зависимости от величины уменьшения живого сечения всех фильтрующих сеток в процессе их засорения и предотвратить осаждение механических примесей в зазоре между цилиндрическими фильтрующими картриджами грубой и тонкой очистки.
