Micro gas turbine ejector

Abstract

A micro gas turbine ejector comprises a connector pipe and an ejector pipe; the connector pipe comprises a gas inlet straight pipe, an exhaust taper pipe and an exhaust straight pipe; the left end of the ejector pipe is connected with the gas inlet straight pipe, and the exhaust taper pipe and the exhaust straight pipe are located in the ejector pipe; a mist oil ring pipe is arranged on the outer wall of the gas inlet straight pipe, a plurality of mist oil spray pipes are arranged on the inner wall of the gas inlet straight pipe, and the mist oil spray pipes communicate with the mist oil ring pipe; gaps exist between the ejector pipe and the exhaust taper pipe and between the ejector pipe and the exhaust straight pipe to form an ejection flow channel; a feeding pipe is arranged on the ejector pipe, and the feeding pipe communicates with the ejection flow channel. The left end of the ejector pipe is directly connected with the gas inlet straight pipe of the connector pipe, the gas backflow phenomenon does not exist, and the gas utilization rate of a gas turbine is increased; according to the ejector, a liquid smoke agent dispensing structure and a powdery smoke agent dispensing structure are provided, the dispensing task of the smoke agents in two states can be met at the same time, and the ejector has the characteristic of multiple purposes.

Description

technical field [0001] The invention relates to the technical field of smoke screen equipment, in particular to a micro gas turbine ejector. Background technique [0002] Under the complex electromagnetic environment, the surface ship formation is extremely vulnerable to the enemy's various advanced equipment reconnaissance detection and precision-guided weapons during sea operations such as berthing points and escorts. Through the use of high-tech materials and their release technology, modern smoke screens have multifunctional smoke screens that absorb, scatter, and reflect visible light, laser, infrared, millimeter waves, and microwaves, which can significantly reduce the probability of being discovered and attacked by the enemy. Actions provide a reliable method for camouflage and concealment. Proper use of modern smoke screens can serve the purpose of camouflaging and concealing surface ship formations, creating false targets, confusing and interfering with the enemy. ...
