Abstract

A flow disturbing type multi-fluid integrated mixer comprises a mixer main body, a mixing core, a fluid A inlet and a fluid B inlet. The mixing core is arranged in the middle of a main flow channel formed in the middle of the mixer main body and comprises a central fixing part, fluid A blades and fluid B blades, wherein the fluid A blades and the fluid B blades are arranged on the side portion of the central fixing part in a rotary mode at intervals. Cavities in the blades pass through a main cavity and then communicate with the corresponding fluid A inlet or the corresponding fluid B inlet. Vent holes are formed in the side portions of the blades. The central fixing part sequentially comprises an inner barrel wall, a middle baffle cavity and an outer barrel wall from inside to outside. The inner barrel wall is provided with a plurality of central vent holes, and a partition wall shaped like the Chinese character "ji" can be arranged in the main cavity so as to divide the main cavity into a main cavity body A and a main cavity body B which are opposite up and down and communicate with the fluid A inlet and the fluid B inlet correspondingly. The flow disturbing type multi-fluid integrated mixer of the design is high in integration degree, three fluids can be mixed, the vortex capacity can be provided for fluid mixing, and the mixing effect is good.

Description

technical field [0001] The invention relates to a mixer, which belongs to the technical field of fluid mixing, in particular to a turbulence type multi-fluid integrated mixer, which is particularly suitable for enhancing the degree of integration and improving the mixing effect. Background technique [0002] At present, in the face of the increasingly severe environmental crisis, the emission regulations of various countries are becoming more and more stringent, and low emission is the main direction of the development of internal combustion engines. EGR as the reduction of internal combustion engine NO x Effective internal purification measures for emissions are one of the important technologies for engines to achieve low emissions. In practical engineering applications, EGR mixing uniformity is an important indicator affecting engine performance. Poor mixing uniformity will lead to poor consistency of engine cycle and cylinders, which will adversely affect engine performa...
