Новая конструкция лопастного раскручивателя циклонного аппарата

The paper presents a new design of a blade untwisting device where blades are considered as a main element of the device. A profile of the blades corresponds to a circular arch. An inlet angle of  the blades is determined by stream aerodynamics in an exhaust pipe, and an exit angle is determined by rectilinear gas motion. Optimum geometrical parameters of the untwisting device have been determined and its application allows to reduce a pressure drop in the ЦН-15 cyclones by 28–30 % while screw-blade untwisting device recovers only 19–20 % of energy.Представлена новая конструкция раскручивателя, основным элементом которого являются лопасти, профиль которых соответствует дуге окружности. Угол входа лопастей определяется аэродинамикой потока в выхлопной трубе, а угол выхода – прямолинейным движением газа. Определены оптимальные геометрические параметры раскручивающего устройства, применение которого позволяет снизить потери давления в циклонах ЦН-15 на 28–30 %, в то время как винтолопастной раскручиватель восстанавливает лишь 19–20 % энергии
