Abstract

FIELD: production of emulsions, suspensions in hydrodynamic cavitation field. SUBSTANCE: mixer has cylindrical housing outfitted with medium supply and discharge branch pipes. Cavitators made in form of equidistant truncated cones arranged radially are mounted in the housing. All cavitators are made at various angles of taper. Under action of incoming flow, cavitators generate non-stationary moving cavities, different in structure and value which break down into cavitation bubbles of various sizes in relatively wide range. EFFECT: enhanced reliability. 2 dwg

Description

Изобретение относится к устройствам для получения эмульсий, суспензий в гидродинамическом кавитационном поле и может быть использовано в химической, нефтехимической, целлюлозно-бумажной, пищевой и других отраслях промышленности. The invention relates to a device for producing emulsions, suspensions in a hydrodynamic cavitation field and can be used in chemical, petrochemical, pulp and paper, food and other industries.

Целью изобретения является повышение эффективности перемешивания. The aim of the invention is to increase the efficiency of mixing.

На фиг. 1 изображен предлагаемый смеситель, продольный разрез; на фиг. 2 сечение А-А на фиг. 1. In FIG. 1 shows the proposed mixer, a longitudinal section; in FIG. 2, section AA in FIG. 1.

Кавитационный смеситель состоит из цилиндрического корпуса 1 с патрубками подвода 2 и отвода 3 среды. В корпусе 1 на ступице 4, проходящей вдоль продольной оси смесителя, перпендикулярно ей размещены кавитаторы 5, выполненные в виде радиально установленных конусных обтекателей с различными углами конусности, на равном расстоянии друг от друга, и неподвижно закрепленных большими основаниями на внутренней поверхности корпуса 1, например на втулке 6, а меньшими на ступице 4. The cavitation mixer consists of a cylindrical body 1 with nozzles for supply 2 and outlet 3 of the medium. In the housing 1 on the hub 4, which runs along the longitudinal axis of the mixer, cavitators 5 are placed perpendicularly to it, made in the form of radially mounted conical fairings with different taper angles, at an equal distance from each other, and fixedly fixed by large bases on the inner surface of the housing 1, for example on the sleeve 6, and smaller on the hub 4.

Кавитационный смеситель работает следующим образом. Cavitation mixer works as follows.

Обрабатываемый продукт через патрубок 2 поступает в корпус 1. При обтекании потоком кавитаторов 5 в нем генерируются нестационарные кавитационные каверны. Перемещаясь в потоке и распадаясь, каверны образуют пульсирующее поле кавитационных пузырьков. Выполнение кавитаторов в виде конусных обтекателей с разными углами конусности способствует тому, что кавитаторами генерируются различные по величине и строению каверны, которые при дроблении образуют кавитационные пузырьки различных размеров и, интенсивно перемешиваясь в зоне схлопывания, насыщают обрабатываемый продукт по всему объему корпуса кавитационного смесителя. При этом единичная концентрация пузырьков в зоне схлопывания увеличивается, кавитационный эффект обработки усиливается. Существенное влияние на интенсификацию кавитационного поля оказывает достаточно широкий спектр поличастотных пульсаций давления, обусловленный различной частотой отрыва от кавитаторов перемещающихся каверн. Пульсации давления, воздействующие не только на схлопывающиеся пузырьки, но и на разрушающиеся каверны, повышают энергетический потенциал кавитационного поля, позволяют достаточно эффективно использовать энергию потока обрабатываемого продукта. The processed product through the pipe 2 enters the housing 1. When flowing around the flow of cavitators 5, unsteady cavitation cavities are generated in it. Moving in a stream and decaying, caverns form a pulsating field of cavitation bubbles. The implementation of cavitators in the form of cone fairings with different taper angles contributes to the fact that cavitators generate cavities of various sizes and structures, which, when crushed, form cavitation bubbles of various sizes and, intensively mixing in the collapse zone, saturate the processed product throughout the entire volume of the body of the cavitation mixer. In this case, a single concentration of bubbles in the collapse zone increases, the cavitation effect of the treatment is enhanced. A significant effect on the intensification of the cavitation field is exerted by a fairly wide range of polyfrequency pressure pulsations, due to the different frequency of separation from cavitators of moving caverns. Pressure pulsations, affecting not only collapsing bubbles, but also collapsing cavities, increase the energy potential of the cavitation field, and make it possible to efficiently use the energy of the processed product stream.

Использование предлагаемого смесителя в химической, нефтехимической, целлюлозно-бумажной, пищевой и других отраслях промышленности позволяет улучшить качество получаемого продукта, например эмульсий, суспензий. Причем повышение степени гомогенизации обрабатываемого продукта достигается за счет интенсификации кавитационного поля и, следовательно, более полного использования энергии потока обрабатываемого продукта. The use of the proposed mixer in the chemical, petrochemical, pulp and paper, food and other industries can improve the quality of the resulting product, for example emulsions, suspensions. Moreover, increasing the degree of homogenization of the processed product is achieved due to the intensification of the cavitation field and, therefore, a more complete use of the energy of the flow of the processed product.

Кроме того, предлагаемое техническое решение конструктивно проще, чем известные аналоги. In addition, the proposed technical solution is structurally simpler than the known analogues.
