- the present invention reveals a machine, system and procedure for disinfection and purification in fuel tanks located in places with high or high relative humidity, avoiding the proliferation of bacteria and fungi that, in addition to contaminating fuels, especially affects the manufacturing metals of the fuel. tank.
- SUBSTITUTE SHEET (RULE 26) Biologically contaminated they experience problems related to fuel quality and fuel storage infrastructure and engine operating system. Microbial contamination problems cause the proliferation of algae or biological mass with a gelatinous form, which is highly corrosive, which clogs engine filters, pipes and injectors and literally devours the metals in the tank that contains it, in addition to reducing the quality of the fuel. own fuel.
- the solution that guarantees the best solution to the problem involves discarding the contaminated fuel and manually cleaning the tank, an extremely expensive process, since in a short period of time we will have the problem again, because normally we can't clean the deposit 100%.
- the tanks are not simple cylindrical or four-walled chambers, but are integrated into the structure of the ship, such as keels, bulkheads, spars, transverse frames. and other reinforcing members, which extend into the spaces of the tank, therefore the cleanliness of the same is extremely important since the integrity of the vessel or pleasure craft depends on the healthiness of the fuel tank.
- Fuel tanks must always be clean of contamination so that the fuel has an acceptable quality, therefore, in the event that a contaminated tank is available, it is necessary to disinfect it so that we can guarantee this objective.
- patent application WO / 2004/103586 discloses a device for the interior washing of spaces in containers, for example ship tanks, in which at least one tube of washing liquid for the supply of washing liquid is provided with at least one washing nozzle for discharging jets of washing liquid, and in which a drive or operation device is provided to rotate the washing liquid pipe around a geometric axis of rotation and the nozzle of washing around another geometric axis of rotation, where the actuator is provided to rotate in opposite directions of rotation by reversing its direction of rotation, a switching device is provided to make the tube of washing liquid or the nozzle
- the washing machine rotates depending on the direction of rotation of the actuator, and that by means of a control system allows to control the actuator device. to rotate in one or the opposite direction of rotation.
- European patent EP0723909 refers to a discharge device for the internal discharge of tanks, preferably tanks in vessels or vessels, by which at least one discharge liquid pipe is provided in a rotatable way in the tank, whereby the pipe discharge liquid has at least one discharge nozzle which is pivotally mounted with respect to the discharge liquid pipe, whereby a supply conduit is provided for feeding discharge liquid to the discharge liquid pipe and, through said pipe, to the discharge nozzle which is adapted to direct jets of discharge liquid towards the internal sides of the tank, whereby a turbine wheel in a turbine device is mounted in the supply conduit so that said wheel is driven by the flow of discharge liquid in said supply conduit and whereby the turbine wheel is provided to drive a set impu lsor located outside the supply conduit and provided rotate the discharge liquid tube and at the same time rotate or rotate the discharge nozzle.

- the radiation time is very important, it also incorporates an adjustable ventilation system (15) with temperature gauges (16) that allows the temperature to be controlled in the desired range throughout the duration of the process.
- the machine (1) is part of an integral fuel filtering, disinfection and purification system that aims to solve a problem that exists in all fuel tanks located in places with relative humidity
- SUBSTITUTE SHEET (RULE 26) medium or high. This humidity causes an unwanted amount of water to accumulate in the tanks by condensation at the bottom, which over time will develop a proliferation of bacteria and fungi that are corrosive, and that in the case of tanks that have an engine, cause problems of obstruction in the fuel absorption system, filters, pipes and injectors, triggering the stop of the engine and problems of corrosion in the metals, this problem being especially serious in boats, since the fuel tank is part of the hull of the boat, and corrosion can cause the boat to sink.
- the system for filtering, disinfecting and purifying the fuel for contaminated tanks comprises a cleaning machine (1) that incorporates a fuel inlet intake; A suction hose (8) to direct the sucked fuel towards the fuel inlet and connected to an extendable suction lance (9), configured so that once inserted inside the fuel tank, it adapts its length allowing fuel to be sucked from the bottom of said fuel tank and which is finished off at its end with a crusher propeller (20) that prevents debris from clogging the system; a high pressure ejection hose (11) to direct high pressure fuel from the fuel outlet of the machine (1) to the fuel tank and is connected at its end located inside the tank to a jet rotating, which when the fuel comes out under pressure, rotates and cleans the walls and bottom of the same; a return hose (12), which eliminates excess pressure by returning excess fuel to the tank; a system for opening and sealing the tank (25) with connectors for the suction (8) and return (12) hoses, which prevents odors and spills while working on cleaning and disinfection;
- the system of the invention also optionally has sensors / indicators for changing or cleaning filters, temperature and process time. Fuse box and magneto-thermal power suitable for the model. Panel of switches and control instruments, in the case of fixed models it has a panel that is installed in the boat or vehicle, in transportable models it is incorporated into the machine itself (1).
- SUBSTITUTE SHEET (RULE 26)
- a procedure for filtering, disinfecting and recycling fuel for contaminated tanks which incorporates several operational stages such as the aspiration of the contents of the tank, by means of the suction hose; separation of fuels with the different filters, elimination of water present in the fuel, radiation with ultraviolet and / or infrared rays and reconversion of the fuel to the tank using a high pressure hose with enough pressure to operate a rotating high pressure jet installed at the end of said hose.
- the procedure begins with a first stage, which is the aspiration of the liquid contained within the fuel tank from the deepest part of the same, with the aspiration hose (8) and by applying an extendable aspiration lance (9) configured to, once inserted inside a fuel tank, draw fuel from the bottom of said tank.
- fuel consisting of an adjustable cap to the hole made with a lower claw and rubber bands for a perfect closure. Said lid will have internal quick connections for all the devices that must be inserted into the tank and external quick connections for connection to the machine.
- a self-suction pump of between 12v and 220v can be implemented and with adequate power for recirculation, in the case of machines that are permanently installed together to the tank, or with high absorption capacity if they must extract the fuel from a certain height
- the machine (1) Once the contents of the tank have been sucked up by the machine (1), it goes to a second stage where the fuel is filtered, separating the biological waste and coarse solid impurities of a size greater than 20 microns from the fuel.
- a filter self-cleaning system can be incorporated, which consists of reversing the circulation flow, so that by means of electro-valves (17) the suction of the absorption intake continues and fuel is returned to an additional tank that g
- SUBSTITUTE SHEET (RULE 26) separates dirt and fuel by decantation, so that no fuel is lost in the cleaning process, when the system restores normal flow, the outlet valve continues for a few seconds to empty fuel into the cleaning tank, to clean the circuit completely, and after that time it returns to the normal operating position causing the fuel to pass to the next phase.
- a fourth stage is carried out to remove the water that is contained in the fuel by means of the centrifuge (6) with a turbine filter (6 ') or just a water separating turbine.
- the water will be dislodged from the system through a drain nozzle located at the bottom of the centrifuge (6) or the water separating turbine and only the fuel continues to be treated.
- the fuel When the fuel is completely clean, it proceeds to a fifth stage consisting of radiation with ultraviolet and / or infrared rays of the fuel inside the radiation chamber (3).
- the user may configure the type of radiation with different wavelengths between 200nm and 800nm, or give it the full spectrum, to kill living organisms or to eliminate chemicals or dyes.
- flow control is included in the radiation chamber (3), being able to adjust the speed of passage through the chamber and consequently the exposure time to said radiation.
- the excess fuel when the selected flow rate is small, returns to the tank after the filtering process without passing through the radiation chamber (3).
- the radiation chamber (3) also has micro chambers through which the fuel circulates with the appropriate thicknesses for the radiation to be effective.
- the fuel is returned to the tank through the high pressure expulsion hose (11) with sufficient pressure to operate a high pressure rotating jet (10) installed at the end of said hose (11) in a way that helps clean the reservoir.
- the materials used are adequate and suitable for handling fuels and have adequate electrical conduits to absorb the static electricity generated in the process.
- Both the frame and the type of pump, filters and other components are adaptable according to the machine model and its requirements, for example, the
- SUBSTITUTE SHEET (RULE 26) Machine that is in a port to serve many ships, in addition to being able to move, it must be much more powerful than the one that is permanently installed on a ship. On the contrary, the latter must be smaller and can be attached to the tank.
