Abstract

Устройство для очистки газов типа трубы Вентури, включающее конфузор, горловину, диффузор, регулирующую вставку, соединенную через шток с приводом, систему орошения, фиксатор, установленный в диффузоре, причем регулирующая вставка выполнена из коаксиально установленных на расстоянии друг от друга элементов, при этом наружный элемент жестко закреплен на штоке с помощью спиц, а внутренний установлен на штоке с возможностью продольного перемещения и имеет упоры, расположенные между спицами наружного элемента, отличающееся тем, что система орошения выполнена в виде коллектора с форсунками, при этом каждая из форсунок содержит корпус, штуцер и, соосно расположенную с ними, вставку-завихритель, а в штуцере выполнен расширяющийся канал для подвода жидкости в цилиндрическое отверстие, которое выполнено осесимметрично корпусу и плавно переходит в, соосное с ним, фигурное отверстие, выполненное в форме сопла Лаваля, а в цилиндрическом отверстии корпуса, осесимметрично ему, установлена цилиндрическая вставка-завихритель, имеющая внешние периферийные винтообразные нарезные каналы, причем по оси вставки-завихрителя выполнено центральное осевое отверстие с винтовой нарезкой на внутренней поверхности, обратной направлению нарезки каналов, при этом вставка-завихритель устанавливается в корпусе через упругие прокладки и поджимается штуцером посредством резьбового соединения корпус-штуцер.A device for cleaning gases such as a Venturi pipe, including a confuser, a neck, a diffuser, a regulating insert connected via a rod to the actuator, an irrigation system, a clamp installed in the diffuser, and the regulating insert is made of elements coaxially installed at a distance from each other, while the outer the element is rigidly fixed to the rod with the help of knitting needles, and the inner one is mounted on the rod with the possibility of longitudinal movement and has stops located between the spokes of the outer element, characterized in that the system irrigation is made in the form of a collector with nozzles, each of the nozzles containing a body, a nozzle and a swirl insert coaxially located with them, and an expanding channel is made in the nozzle for supplying fluid to a cylindrical hole, which is made axisymmetrically to the body and smoothly passes into, coaxial with it, a figured hole made in the form of a Laval nozzle, and a cylindrical swirl insert having external peripheral helical threaded channels is installed in the cylindrical hole of the body, axisymmetrically to it and, along the axis of the swirl insert, a central axial hole is made with screw thread on the inner surface, the reverse direction of the channel cutting, while the swirl insert is installed in the housing through elastic gaskets and is pressed by the fitting by means of a threaded housing-fitting connection.
