Достоинство насадочных колонн заключается в высокой эффективности, низком гидравлическом сопротивлении, широком интервале устойчивой работы. Важнейшими требованиями, предъявляемыми к насадкам, являются: высокая удельная поверхность, большая доля свободного объема, простота изготовления и низкая материалоёмкость. Однако в настоящее время нет насадок, удовлетворяющих всем требованиям, предъявляемым к ним. Это обусловливает тенденцию к разработке и использованию новых насадочных контактных устройств. В статье представлены результаты гидравлических испытаний разработанной спиралевидной насадки, которая может быть применена для осуществления тепломассообменных процессов в ректификационных, абсорбционных, экстракционных колоннах и градирнях. Несложная конструкция насадки позволяет изготавливать её путём сварачивания металлической полосы в цилиндрическую спираль. Такая форма насадки позволяет исключить контакт соседних элементов, что препятствует блокированию поверхности насадки и образованию застойных зон. Особенностью данной конструкции является то, что насадка имеет гладкий профиль и на нем нет элементов, которые могли бы быть центром образования отдельных капель и струй, снижающих эффективность массопередачи. Пленочный характер стекания жидкости с элемента насадки обеспечивает высокие массообменные характеристики при минимальном значении уноса и способствует снижению гидравлического сопротивления. На основе экспериментальных данных получены эмпирические уравнения для расчета гидравлических сопротивлений сухой и орошаемой насадки. Приведены сравнительные характеристики спиралевидной насадки с кольцами Палля и насадки «Инжехим-2000». Показано, что разработанная спиралевидная насадка имеет большую удельную поверхность, значительный свободный объем, низкое гидравлическое сопротивление, несложную конструкцию, что уменьшает себестоимость ее изготовления.</p></abstract><trans-abstract xml:lang="en"><p>A large number of different packing elements are applied in the chemical, oil refining, petrochemical, food and other industries for implementing heat-and-mass transfer processes in columns. The advantage of packed columns consists in their high efficiency, low flow resistance and stable operation. The most important requirements for packing elements include their high specific surface area, large free volume proportion, ease of manufacture and low material consumption. However, few available packing elements meet all of the aforementioned requirements. In this work, we developed a helical packing element for implementing heat-and-mass transfer processes in distillation, absorption and extraction columns, as well as in cooling towers, and carried out a series of respective hydraulic tests. The novel packing element is characterized by a simple design, implying coiling a metal strip into a helix. Such a shape excludes the contact with neighbouring elements, which prevents blocking of the packing surface and formation of stagnant zones. A specific feature of this design consists in the smooth surface of the element, which prevents the formation of drops and streams, thus reducing the mass transfer efficiency. The film-like flow through the packing element ensures high mass transfer characteristics with minimum entrainment, thus contributing to the reduction of flow resistance. On the basis of experimental data, empirical equations were obtained for calculating the flow resistance of dry and wet packing patterns. A comparative analysis of the developed packing element with Pall Rings and Inzhekhim-2000 is provided. It is shown that the developed helical packing element is characterized by a large surface area, significant free volume and low flow resistance. In addition, the simple design of the element significantly reduces its production costs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>массообменные аппараты</kwd><kwd>спиралевидная металлическая насадка</kwd><kwd>колонны ректификационные</kwd><kwd>абсорбционные</kwd><kwd>экстракционные</kwd><kwd>конструирование насадочных элементов</kwd><kwd>гидравлическое сопротивление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mass transfer devices</kwd><kwd>helical metal packing</kwd><kwd>fractionating</kwd><kwd>absorption and ex-traction columns</kwd><kwd>design of packing elements</kwd><kwd>flow resistance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каган А.М., Лаптев А.Г., Пушнов А.С., Фарахов М.И.
