A helicopter engine air inlet energy-saving sand discharging device based on a vortex tube separator comprises an upper panel provided with an air inlet hole, a lower panel provided with an exhaust hole and a sand discharging chamber arranged between the upper panel and the lower panel. A vortex tube separator is arranged in the sand discharging chamber, an air inlet of the vortex tube separator is connected with the air inlet hole of the upper panel, an air outlet of the vortex tube separator is connected with the air outlet hole of the lower panel, and a tube body of the vortex tube separator is provided with a sand discharging channel communicated with the sand discharging chamber; a sand discharging opening is formed in the side face of the sand discharging chamber and connected with an injection pipe, the injection pipe is connected with a gas entraining pipeline capable of providing injection high-pressure gas, and the gas entraining pipeline introduces the high-pressure gas from engine tail gas. According to the Bernoulli principle, under the action of large pressure difference, sand grains in the sand discharging chamber are discharged to the outside through the injection pipe, so that the problems that a traditional sand discharging device for helicopter air inlet needs to be externally connected with a motor and fan blades are prone to abrasion are solved, energy is saved, and the service life of the device is prolonged.
一种基于涡旋管分离器的直升机发动机进气节能排砂装置,包括开设有进气孔的上面板、开设有排气孔的下面板以及设置在上面板与下面板之间的排砂室;所述排砂室的内部设置有涡旋管分离器,涡旋管分离器的进气口与上面板的进气孔相连,涡旋管分离器的排气口与下面板的排气孔相连,涡旋管分离器的管身设置有连通排砂室的排砂通道;排砂室的侧面开设排砂口并连接引射管,所述引射管连接能够提供引射高压气体的引气管路,所述的引气管路从发动机尾气引入高压气体。本发明根据伯努利原理,在较大的压差作用下,排砂室中的砂粒由引射管排到外界,从而避免传统直升机进气用排砂装置需要外接电机和风扇叶片易磨损的问题,节约能源,延长装置的寿命。
