A kind of fuel oil mixer assembly and oil mixing method for aerospace engine

Abstract

The invention belongs to the technical field of fuel oil mixing devices, and particularly relates to a fuel oil mixing device component for an aerospace engine. The fuel oil mixing device component comprises a spherical oil mixing body. A spherical cavity is formed inside the spherical oil mixing body. A plurality of oil inlet cavity pipes and an oil outlet cavity pipe are arranged on the spherical oil mixing body. Both the oil inlet cavity pipes and the oil outlet cavity pipe are communicated with the spherical cavity. An oil nozzle is mounted on the oil outlet cavity pipe. A plurality of ellipsoidal stirring balls are arranged in the spherical cavity. Detachable oil-filter screens are arranged in both the oil inlet cavity pipes and the oil outlet cavity pipe, and comprise circular oil-filter screen bodies. A plurality of tapered holes are formed in each oil-filter screen body. A plurality of wedged gaps are formed on the edge of each oil-filter screen body in the radial direction. The invention further relates to a method for mixing oil by adopting the fuel oil mixing device component for the aerospace engine. The Fuel oil mixing device component and the method have the advantages that liquids, solids and gases are mixed comprehensively, and the mixing is uniform and sufficient, so that the conditions that the mixed oil burning is sufficient, and the content of exhaust pollutants is low are ensured.

Description

technical field [0001] The invention belongs to the technical field of fuel oil mixers, and in particular relates to a fuel oil mixer assembly for an aerospace engine, and also relates to a method for mixing oil by using the fuel oil mixer assembly. Background technique [0002] In the field of aerospace fuel nozzle technology, it is necessary to mix different oil grades of fuel, catalysts, accelerators, etc., including the comprehensive mixing of liquids, solids and gases. During the flight, it is necessary to fully mix different grades and types of liquids, solids, and gases. There is currently no good oil mixing method for this kind of mixing. Trident tubes, T-shaped tubes, or cross tubes are used for mixing in the early stage. This initial mixing method cannot be fully mixed, and high-level mixing cannot be achieved. At the same time, due to uneven mixing, it will lead to insufficient combustion, insufficient fuel combustion conversion energy, and exhaust emissions will ...

During the flight, it is necessary to fully mix different grades and types of liquids, solids, and gases. There is currently no good oil mixing method for this kind of mixing. Trident tubes, T-shaped tubes, or cross tubes are used for mixing in the early stage. This initial mixing method cannot be fully mixed, and high-level mixing cannot be achieved. At the same time, due to uneven mixing, it will lead to insufficient combustion, insufficient fuel combustion conversion energy, and emissions will also cause exhaust pollution.
