Description

The method for the Production of Nano-Emulsion of water with heavy fluid fuels

TECHNICAL FIELD:

This invention is about fossil fuels including fuels with relatively larger molecules, mixing procedure of water with fuel and required equipment for it and the aforementioned fuels' functions.

BACKGROUND OF THE INVENTION:

One of these methods is the production of water-fuel emulsion. According to this method, emulsion is the procedure through which materials such as water, oil or gasoline, which cannot be combined by one another, by nature, are mixed in order to make a temporary suspension by reducing particles' size. However, suspension recovers into its early form as time passes by, in which materials used to be in two separate phases. The time during which suspension switches back into its earlier version is dependent on the viscosity type, particles' size and mixed materials' combination ratio as well as the temperature .In particular, if the particulate matters' size reduces to sub-micron, the mixture tends to keep the fluid state of emulsion for longer time. More amount of added water to the fuel leads to the production of fuel emulsion in the water whereas the reverse combination ratio would lead to water emulsion in fuel. Water emulsion in fuel can improve combustion efficiency while burning. The mechanism is such that water particles get evaporated and dispersed in an explosive manner as a result of heating. One gram of evaporated water gets 1244 times as voluminous and in its course disperses the surrounding fuel particles, which accordingly reduces the fuel particles' size. Smaller fuel particles have larger surface contact with oxygen and finally will finally improve the combustion efficiency.

Among the water emulsion in fuel samples is Mr. Viktor Maschenko's invention with registration number of EP20100741445 in which using a reactor cavitation, mixture of Mazut fuel with water of 120 degrees and stirring a turbulence in the flow, between the rotor wall and stator that is located on stator of parallel cavities, brings about the mixture of fuel and water and accordingly the creation of water emulsion in fuel.

In registration file of another invention with registration number of WO2013169669 Al by Victor Gurin, Mindaugas MACIJAUSKAS, Pavel Pikul and Serguei Permikov applied to register an invention about the system of producing water emulsion in fuel, in which they make use of the advantages of water emulsion in fuel by mixing gas, water, and fuel and injecting the produced mixture to the engine. In the past, many cases of fossil fuels which have been turned to emulsion by water have been examined. Hence, as regards the problems occurred by previous inventions are the quick switch of the fuel into two distinct phases and the large size of the fuel particles in the emulsion.

THE DESCRIPTION OF THE INVENTION: For resolving the problems mentioned above, the present invention produces the fuel-water emulsion with a particular method and a reactor. Due to the longevity of produced emulsion's homogenized state and very small size of suspended particulate matters in emulsion, it is applicable in most of industrial cases.

This invention is a set of equipment and method for the production of Nano- Emulsion of fuel and water, in which, according to fig.1 , fuel enters the emulsion production line through entrance pipe (fig.1 , partl) and later enters circulation pump by passing through control valve which is connected to production line management structure (fig.1 , part3) Afterwards, it is dispatched to maintenance repository.(fig.l part l l)In the meantime, fuel enters the repository through electronic control valve. The fuel is drained to main fuel tank after passing the dosing system by the help of a pump( fig.l part 8) Exit path through which the fuel mixed with additives is led to main pump's dosing by a pumping aid is designed under the tank. Passing through the dosing system enables the supervision of fuel inflow rate to the mixer (fig.l, part l2)On the other hand, pure water finds its path to the control valve through the pipeline in fig.l part 20 and by entering control valve (fig.l part 19)and enters water repository rank (fig.l, part 17) Later, water can be ushered to water pump dosing(fig.l, part 14) by passing through the control valve(fig.l, part 13) Afterwards, water enters the mixer with specific volume flow rate.(fig.l, part 12)

Inside the mixer (fig.5), there occurs a great deal of turbulence due to the numerous layers with corresponding angles and flowing movement. Occurring turbulence causes the water and fuel particles to mix and accordingly a heterogeneous emulsion with bigger particles. The pass of primary fluid emulsion through control valves(fig.l, parts 21& 25) helps to control the staying duration of primary emulsion inside cavitation(fig.l, part 22). According to the flow rate of water (discharge) from reactor by pump and outflow discharge rate which is adjusted by control valve (fig.l, part26), the product can be utilized directly or dispatched to the reservoir tank.

Taking the electric current flow rate in production line and the chance to increase it in comparison to the exit as well as for controlling the staying duration of materials in each section, another exit (fit.l, part 23) from secondary wall of the reactor in the form of bypass is sent inside the line before the mixer.

The mixture of fuel and water is thrown out of the rotor holes when they enter cavitation reactor because of high velocity of rotor. They also tend to move towards the inner crust of stator. In the meantime, due to having a bigger diameter of rotor's surface in comparison to bed diameter of rotor's holes, linear speed of fluid in created column in rotor's holes is higher than its speed in the hole’s bed. Henceforth, acceleration difference of the fluid in the created column and rotor holes’ bed, fluid undergoes a microscopic extension which in turn leads to the formation of vacuum bubbles. After the fluid containing vacuum microscopic bubbles to the environment between rotor and stator, the fluid tends to switch back to its earlier state, which in turn triggers the microscopic hits against existing particles and accordingly causes strife as a result of this shock. In other words, the created cavitation causes the particles to get pulverized and mixed together. The more the particles stay inside the reactor, the smaller the particles become and more homogenized the mixture gets. Bearing in mind that created particles in this invention are much smaller than micro scale and settle among one another in a homogenized manner, the existing force between two different fluids' molecules is stronger than molecular attraction, which henceforth hinders the union of similar particles and prevents the emulsion to get two-phase status.
