Abstract

Предложен вариант пневматической форсунки, содержащей корпус 1 с внутренней кольцевой газовой камерой 3 и патрубок 2 для подвода в неё сжатого газа, установленную по оси корпуса трубу подачи жидкости 4, переходящую в диффузор 5, и кольцевое щелевое газовое сопло 7, сформированное кольцевой насадкой 6 и корпусом 1 форсунки на выходе из внутренней кольцевой камеры 3. Кольцевое щелевое газовое сопло установлено на срезе диффузора 5 и имеет коническую форму с углом конусности от 60 до 150°, внутренняя кольцевая газовая камера 3 форсунки дополнительно снабжена двумя соплами 8, установленными напротив друг друга, причем оси сопел пересекаются или скрещиваются так, что угол между осью каждого сопла 8 и осью симметрии пневматической форсунки составляет от 30 до 90°, при этом суммарная площадь поперечных выходных сечений сопел 8 составляет 0,3-1 площади поперечного выходного сечения щелевого кольцевого газового сопла 7. По второму варианту пневматической форсунки кольцевое щелевое газовое сопло 7 установлено на срезе диффузора 5 и имеет коническую форму с углом конусности от 60 до 150° и выходное поперечное сечение с переменной площадью по периметру кольца. Конструкция форсунок обеспечивает дисперсность распыливания жидкостей и суспензий без быстрого износа оборудования и возможность управления размерами и формой газокапельного факела.A variant of a pneumatic nozzle comprising a housing 1 with an inner annular gas chamber 3 and a nozzle 2 for supplying compressed gas thereto, a fluid supply pipe 4 installed along the axis of the housing, passing into a diffuser 5, and an annular slotted gas nozzle 7 formed by an annular nozzle 6 and the nozzle body 1 at the outlet of the inner annular chamber 3. The annular slotted gas nozzle is mounted on the cutout of the diffuser 5 and has a conical shape with a taper angle from 60 to 150 °, the inner annular gas chamber 3 of the nozzle is optional provided with two nozzles 8 installed opposite each other, and the axis of the nozzles intersect or cross so that the angle between the axis of each nozzle 8 and the axis of symmetry of the pneumatic nozzle is from 30 to 90 °, while the total area of the cross-section of output sections of the nozzles 8 is 0.3 -1 of the cross section of the output section of the slit annular gas nozzle 7. According to the second variant of the pneumatic nozzle, the annular slit gas nozzle 7 is installed on the cut of the diffuser 5 and has a conical shape with a taper angle from 60 to 150 ° and output cross section with a variable area around the perimeter of the ring. The design of the nozzles provides dispersion of atomization of liquids and suspensions without rapid wear of equipment and the ability to control the size and shape of the gas-droplet flame.
