ECOLOGICAL PROPELLER WITH PRESSURE WATER JET

DESCRIPTION OF THE INVENTION

I. Patent application A / 00121 / 04.03.2020 Ecological power plant proposes the production of electricity using the classic hydropower solution which involves the introduction in a submerged hydraulic turbine at depths of the order of hundreds of meters of a jet of water below liquid column pressure. This variant does not allow the installation of the power plant with permanent operation at altitudes up to 20 meters deep, in lakes formed on watercourses or in the water accumulation lakes of existing hydropower plants or in marine waters, a variant that would be a great opportunity for creation with new costs of new sources of electricity ,.

II. One of the activities with the greatest impact on the environment, if not the first, is the transport of people and goods. If solutions for land transport have been outlined by promoting electric cars or fuel cells, by introducing fuel cells and in rail transport and testing fuel cells on aircraft, for naval transport, no solutions have been found yet.

Today, tens of thousands of ships are in operation, with generators consisting of diesel-powered diesel engines and power generators to power the ship's propulsion engines and other consumers, such as bilge pumps, air compressors, lighting. , etc. The largest naval diesel engine is with Common rail technology, can develop 109,000 horsepower at 102 rpm and 7,603,850 Nm and has a cylinder capacity of 1820 liters per cylinder, the in-line 14-cylinder diesel unit weighs 2,300 tons , has a height of 13.4 meters and a length of 27.4 meters and each of the 14 cylinders consumes 0.19 liters of diesel in each cycle, the 102 revolutions per minute thus leading to consumption at 271.32 liters of diesel per minute per load, ie 16,279.20 liters per hour of operation. If we take into account that several hundred such engines are now in operation that equip cargo and cruise ships, abandoning them or at least reducing the operating times of diesel engines on ships requires immediately applicable solutions.

There is no new technical solution capable of significantly reducing flue gas emissions into an engine invented in the late 19th century and continuously improved in terms of fuel used, if the original engine ran on peanut oil and diesel today, Dedicated fuel, we understand that in order to protect the Earth's atmosphere from emissions and heat from internal combustion engines, we must look for another solution for driving power generators.

An alternative could be the use of nuclear energy, but the current technology has as its subject a nuclear bomb whose explosion is moderated by various methods and which inevitably produces radioactive waste which is now deposited in the deep waters of the terrestrial ocean and is a permanent danger to Tera, to which is added another danger, that of terrorist acts on these reactors.

The solution to providing electricity with fuel cells is not economical and environmentally friendly because these ships can require instantaneous power of up to 100 MW and should have thousands of fuel cells and their drawbacks: it releases heat into operation; use platinum electrodes that are expensive; hydrogen extraction. from fossil fuels or biomass for use in fuel cells requires a lot.

EN 135583 AO energy and emits carbon dioxide, and its retention requires excess energy, increasing the cost of gas and undermining the environmental benefits of using it; it is necessary to create infrastructure for the supply of hydrogen in ports; the flammable nature of hydrogen has obvious safety concerns when stored in large quantities, causes prohibitive costs per tonne transported and makes them unusable now.

Over the last 20 years, the desire for high-speed ships has increased, and so the jet pump used since the 1970s on small or pleasure craft is gaining popularity on larger boats, military ships and ferries, for propulsion using and 3-jet variants. On these larger boats, the pumps can be powered by diesel engines or gas turbines. Speeds up to 40 knots (75 km / h) can be achieved with this configuration, even with a displacement hull. Pump-powered vessels are very maneuverable. Examples of ships using pumpjets are patrol boats, military ships, ferries, submarines.

Pump jets have advantages over empty propellers for certain applications, usually related to the requirements for high-speed or shallow operations: higher speed; high power density; improving shallow water operations, as only the inlet needs to be submerged; increased maneuverability, by adding a directional nozzle to create geared traction; noise reduction, resulting in a low sonar signature. But, as I mentioned, these latest spectacular creations are also dependent on diesel engines or gas turbines, being environmentally friendly.

The present invention aims to remove the shortcomings highlighted by the creation of an ecological propellant with pressurized water jet, which can be used both for the production of electricity in ecological plants located on the surface of the water, possibly in the hull of ships and for the propulsion of ships of any type.

The engine shall consist of at least two explosion chambers of horizontal tubular combustible gas and air mixtures connected to a closed pipe at one end by a perforated plate allowing flooding of the pipe and at the other end by a specific nozzle. the recipient of the pressurized water jet. Combustible gases suitable for the stated purpose, of which we mention, without being an exhaustive list: natural gas, hydrogen, gases obtained by the gasification of coal, wood pellets or household waste, must produce by explosion only water-soluble and chemically inactive compounds . They will be able to adapt to use in environmentally friendly jet engines and liquid fuels used by internal combustion engines, if this solution is of interest. When the explosion occurs, the temperature in the explosion chamber can instantly reach temperatures above 2,000 ° C and pressures above 35 bar. The blast is directed to the flooded pipe through a pipe that penetrates it perpendicularly and has a sectioned end to direct the jet to the nozzle end, where it causes instantaneous evaporation of water and solubilization of carbon dioxide with a significant increase in pipe pressure, pushing the water into the nozzle and from here to the final recipient, in this case either a sea or river vessel or a hydraulic turbine. In both cases, it is important to keep the speed of the ship in motion, or the speed of the hydraulic turbine rotating in strict parameters, in order to ensure a smooth movement of the ship, respectively a stable speed of the turbine that drives a power generator and therefore are precision dispensers for fuel and air supply as well as (

Z

RO 135583 AO scheduler of the time allocated to each phase of engine operation. Therefore, the higher the number of horizontal tubular explosion chambers, the more secure the parameters of the officials required by the application are maintained.

This water jet engine is environmentally friendly because the explosion of the mentioned fuels, with the exception of hydrogen, releases carbon dioxide, water-soluble gas and compatible with aquatic ecosystems, and the hydrogen explosion produces water.

From the design phase, the correlation of the pipe diameters will be followed, so that when the flow and pressure parameters of the water jet are reached, its temperature will be substantially equal to that of the ambient water.

The use of one or more ecological water jet propellers in the ecological power plant allows its installation above any water mirror that can ensure the flow required for water recirculation through the hydro unit and the pipe 16 of each water jet engine under pressure will be submerged at the level of the mirror. water. This is also a great opportunity to increase the power installed in existing hydropower plants by installing environmentally friendly power plants with continuous operation in water storage lakes.

Also, green power plants can be placed on the platform of current thermal power plants or nuclear power plants, using in common their water supply facilities, transformer stations and high voltage lines for the transport of electricity and maintenance services.

For any type of river or sea vessel, it will be possible to provide the electricity necessary for the operation of its installations and equipment by arranging in the hull of an enclosure that will have a water basin over which will be mounted a hydro unit and one or more jet engines. pressurized water that will have the pipe 16 submerged in the water mirror and therefore the volume of water in the pool, which is recirculated through the hydro unit, must ensure the flow required by the propellant or propellants.

Ecological jet engines will also be able to move large cruise ships, cargo or oil tankers with beneficial effects on speed and travel conditions.

The following is an example of an ecological pressurized water jet engine in connection with the attached drawing showing a two-chamber explosion engine in two views: front (fig. 1) and side (fig.2).

The environmentally friendly jet engine has at least two explosion chambers of a mixture of combustible gases and air, horizontal tubular, marked with 1 on the drawing, in which through the supply line, marked with 2 on the drawing, the compressed gases are introduced by opening the valve, marked with 3 on the drawing, by the cam marked with 4 on the drawing, which compresses the spring marked with 5 on the drawing when the camshaft, marked with 6 on the drawing, by the rotation made by the gear motor, marked with 20 on the drawing, brings it above valve. Axis 6 will have for each blast chamber a cam positioned according to the programming desired by the engine designer and will rotate at variable speed to ensure the power required by consumers at all times. The side wall of the tubular chamber, marked 7 on the drawing, is perforated to allow compressed air to enter the duct marked 8 on the drawing when the valve is opened.

RO 135583 AO electromagnetic drive and all-nothing operation, marked with 9 on the drawing. The compressed fuel gas is first introduced into the blast chamber and, when valve 3 is closed, the valve 9 is opened and the spark plug 10 starts to produce sparks which ignite the air-gas mixture and then the explosion occurs which causes the movable wall marked 11 to move on the compressed drawing. the spring marked with 12 on the drawing and controls the closing of the valve 9 and the spark plug 10. The blast passes into the pipe marked with 13 on the drawing which is connected by the pipe marked with 14 and the elastic connection marked with 15 to the pipe marked with 18 on the drawing mounted perpendicular to the pipe, marked with 16 on the drawing, and is sectioned obliquely to direct the blast in one direction. Pipe 16 is submerged at the surface of the water and flooded through the perforated wall marked 17 on the drawing and when the blast reaches it its high temperature produces instantaneous vaporization of the water and solubilization of carbon dioxide increasing the wind pressure and through the nozzle marked 19 on the drawing pressurized water jet produces mechanical work. From the explosion to the formation of the water jet the temperatures of the fluid are high and therefore all the components that come in contact with it: explosion chamber 1, pipes 13, 14, 16, 17, 18, elastic connection 15 are thermally insulated to do not dissipate heat in the environment.
