Nano-additive fuel hypergravity mixing device for marine engine

Abstract

The invention discloses a nano-additive fuel oil supergravity mixing device for a marine engine, which comprises a mixing chamber, a premixing chamber and a rotating rotor, the rotating rotor is installed in the mixing chamber through a rotating pair, and the premixing chamber is arranged in the mixing chamber On the top, the premixing chamber is provided with fuel inlet and additive inlet pipes, and the lower part or side wall of the premixing chamber is provided with one or more fuel spray pipes, and the fuel spray pipe is provided with one or more facing rotating rotors. The hollow inner wall spraying nozzle, the bottom of the mixing chamber is provided with a fuel outlet, and the rotating rotor is driven by the power system to rotate at a high speed, which is used to centrifugally overweight the mixed fuel sprayed on the hollow inner wall of the rotating rotor. After the centrifugal overweight, the mixing The fuel permeates from the rotating rotor to the outer wall, flows down the inner wall of the mixing chamber and gathers at the fuel outlet. The invention realizes high-efficiency microcosmic mixing of the nano-additive fuel, thereby ensuring the real-time stability of the nano-additive fuel and improving the utilization rate of the fuel.

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
