Nano additive fuel super-gravity mixing device for marine engine

Abstract

The invention discloses a nano additive fuel super-gravity mixing device for a marine engine. The nano additive fuel super-gravity mixing device comprises a mixing chamber, a premixing chamber and a rotary rotor, wherein the rotating rotor is installed in the mixing cavity through a rotating pair, the premixing cavity is arranged at the top of the mixing cavity, a fuel inlet and an additive inletpipe are arranged on the premixing cavity, one or more fuel spraying pipes are arranged on the lower part or the side wall of the premixing cavity, one or more nozzles for spraying the hollow inner wall of the rotating rotor are arranged on the fuel spraying pipe, the bottom of the mixing cavity is provided with a fuel outlet, the rotating rotor is driven by the power system to rotate at high speed, the mixed fuel sprayed on the hollow inner wall of the rotating rotor is subjected to centrifugal overweight, and after centrifugal overweight, the mixed fuel permeates from the rotating rotor to the outer wall, and then the mixed fuel flows down along the inner side wall of the mixing cavity to the fuel outlet. According to the nano additive fuel super-gravity mixing device, efficient micro-mixing of the nano additive fuel is realized, so that the real-time stability of the nano additive fuel is ensured, and the fuel utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of engines, and relates to a fuel and additive mixing technology, in particular to a nano-additive fuel supergravity mixing device for a marine engine. Background technique [0002] Nano-additive fuel is to add a certain amount of nano-particles to the fuel, and carry out surface modification treatment and fully mix with the dispersion medium to form a solid-liquid suspension. Due to its small size and surface effect, nano-sized particles will not damage the fuel supply system and combustion chamber, but can also improve the atomization and evaporation performance of the engine, accelerate the ignition of fuel, improve fuel combustion efficiency, reduce emissions, etc. Purpose. In the era of sharply rising global oil prices, the market prospect of nano-additive fuel is extremely broad. [0003] Since the nano-additives are solid particles, the surface properties of the particles and the dispersion medium a...

Problems solved by technology

Through the synergistic effect of the mechanical stirrer and the baffle, the stirring equipment can make the liquid move comprehensively in the circumferential and radial directions. However, it only achieves the effect of macroscopic mixing on the scale, and it is difficult to achieve the solid-liquid microscopic mixing on the molecular scale.

[0004] For marine engines, the fuel consumption during operation is large, and there is still a vacuum period for fuel use such as docking when the hull is sailing. With the changes in the concentration ratio of nanoparticles and the external environment, nano-additives The stability of fuel oil will also change accordingly. The existing preparation process is difficult to ensure the long-term stable storage of nano-additive fuel. for marine engines
