Description

An internal combustion engine power generation system using functional water electrolytic gas and fossil fuel}

The present invention relates to an internal combustion engine power generation system, and more specifically, by using a mixed fuel obtained by mixing water electrolysis gas consisting of hydrogen and oxygen obtained by electrolyzing water with organic compounds and air as fuel for an internal combustion engine. This relates to an internal combustion engine power generation system using functional water electrolysis gas and mixed fuel that has the function of preventing backfire and significantly reduces environmental pollutant emissions.

The Earth is suffering from serious environmental pollution due to excessive use of fossil fuels, and oil prices are soaring every day due to the depletion of limited resources. Therefore, it is true that mankind has made every effort to develop pollution-free energy such as solar heat, wind, and tidal currents, but has not achieved significant results due to lack of economic feasibility.

Water is the best energy resource that can be easily obtained from nature. It is said that water has about 3.8 times more energy than oil. Therefore, if water can be burned, the energy problem is solved.

In order to use water as fuel, you must first know the characteristics of water electrolysis gas.

Water electrolysis gas (water electrolysis gas, Brown gas) refers to a mixed gas of hydrogen and oxygen produced by electrolysis of water in a mixing ratio of 2:1, and is a completely pollution-free fuel that is reduced to water vapor after combustion. .

In addition, water electrolysis gas meets the conditions for complete combustion with a chemical equivalence ratio of hydrogen and oxygen of 2:1, so it has the characteristic of being completely burned by its own oxygen even without air supply like fossil fuels.

In addition, water electrolysis gas has implosion characteristics, which are the opposite of explosion, so the flame travels straight without rupturing, forming a pinpoint flame.

In addition, water electrolysis gas has thermonuclear reaction characteristics, so the material heated by thermonuclear reaction with hydrogen and oxygen results in being heated by a much hotter flame than when the gas burns alone in air.

In this way, unlike hydrogen gas, water electrolysis gas has unique characteristics of water electrolysis gas, so a new combustion method must be found, unlike the previous combustion method that requires the input of air.

Additionally, hydrogen-oxygen mixed gas can be easily obtained by electrolyzing water. When water is electrolyzed, a 2:1 mixed gas of hydrogen and oxygen molecules is created, as the molecular formula of water is H ₂ O. A mixed gas with this ratio is called detonation, and the ratio that causes an explosion is the hydrogen in the air. This is when the mixture is 4 to 75%.

In addition, it explodes most violently when hydrogen is about 28% (oxygen is 66%). This reaction produces 2 mol of water vapor from 2 mol of hydrogen and 1 mol of oxygen, generates 58.3 kcal of heat, and the temperature is 4,710℃ and pressure is 12atm. do. In other words, it is a reaction that produces water, and when this ratio is appropriate, the risk of explosion is high.

Ultimately, the 2:1 mixed gas of hydrogen:oxygen, which is the ratio of the reaction in which water is created, reacts violently and explodes above 500℃. As the mixed gas of hydrogen and oxygen remains in an unsafe state, there are difficulties in storing or directly using this mixed gas for safety and economic reasons.

In addition, the wide flammability limit, low ignition energy, and fast combustion speed of hydrogen fuel cause early ignition and backfire, which are the biggest keys to the development of hydrogen engines in high-load operation areas. The combustion speed of a mixed gas of hydrogen and oxygen or air is greater than that of hydrocarbons, and at 1 atmosphere of pressure, it is about 2.7 m/sec for a hydrogen-air mixed gas (about 40 vol% oxygen) and about 9 m/sec for a hydrogen-oxygen mixed gas. (Hydrogen: about 70 Vol%).

Therefore, it can be seen that a device to prevent backfire through such a fast combustion speed is absolutely necessary.

The mixed gas of hydrogen and air is free from harmful emissions and particulate matter containing carbon and sulfur components. Only because the adiabatic flame temperature of hydrogen is higher than that of petroleum-based fuels does the production of NOx increase. Reduction of NOx alone is relatively easy and low-temperature catalysts are possible, so an exhaust level close to zero pollution is possible.

Since the hydrogen contained in the mixed gas is burned through the internal combustion engine, the temperature inside the combustion chamber of the engine increases and the amount of thermal NOx (nitrogen oxides) generated increases. This is due to the relatively high adiabatic flame temperature of hydrogen (H ₂₎ and the rapid combustion. It can be seen that the combustion speed promoted the production of thermal NOx. This means that when applied to an internal combustion engine that mixes hydrogen (H ₂ ), the amount of thermal NOx generated must be reduced by using exhaust gas recirculation (EGR), selective catalytic reduction (SCR), or other methods.

Hydrogen in water electrolysis gas has a high calorific value of 34,000 Kcal per 1 kg, which is about 2.7 times the calorific energy of gasoline. It can be produced from water, so it is eco-friendly and does not contain carbon dioxide (CO ₂ ), the main cause of global warming. It can be safely used as clean energy.

In other words, Brown gas, which is a premix of hydrogen and oxygen generated by electrolyzing water in an equivalent ratio, is explosively reactive and causes backfire or flame lift-off, so it must be used in a special type of burner or flame. Stabilizers, etc. are required.

Recently, power generation systems using hydrogen have been developed, and fuel cell power generation systems have been commercialized and used as such hydrogen power generation systems. The fuel cell power generation system produces hydrogen by electrolyzing water or natural gas, which exists in abundance on Earth, and supplies the produced hydrogen as fuel to the fuel cell, converting the chemical energy of hydrogen into electrical energy and generating direct current. It is a system that produces electric current.

However, the fuel cell power generation system using hydrogen has the advantage of generating power by converting the chemical energy of hydrogen into electrical energy through a fuel cell, so it does not emit pollutants and can generate infinite power without mechanical contact. Since it is used for power generation and converted into heat and electric energy, it has the disadvantage of consuming as much fuel as the heat and electric energy produced. In other words, the cost of producing, compressing, and delivering the hydrogen used as fuel for the fuel cell to the power plant was high, which resulted in low business feasibility.

Therefore, research to generate electricity using water electrolysis gas as described above is continuing.

Other methods using hydrogen include the “Internal Combustion Engine Power Generation System Using Hydrogen” in Registered Patent No. 10-1371955.

In addition, as a related technology, the published patent (10-2022-0153783, hereinafter referred to as prior art), “Internal combustion engine power generation system using mixed gas and water electrolyte gas,” refers to “producing water electrolysis gas consisting of hydrogen and oxygen by electrolyzing water.” It contains a water electrolysis gas generator and a liquid containing a reducing agent that receives the water electrolysis gas produced from the water electrolysis gas generator, prevents backfire, which is a phenomenon in which a flame flows backwards, and simultaneously suppresses the production of nitrogen oxides.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The present invention includes a water electrolysis gas generator (100), a backfire prevention mixed combustion gas generator (200), a mixed fuel supply device (300), a mixed gas supply device (400), an internal combustion engine (500), and a generator (600). An internal combustion engine power generation system (1000) using functional water electrolysis gas and mixed fuel is provided.

In addition, the present invention provides the water electrolysis gas generator 100, the flashback prevention mixed combustion gas generator 200, the mixed fuel supply device 300, the mixed gas supply device 400, the internal combustion engine 500, and the generator 600. ), and further includes a control device 700 that controls the operation and valves of the surge tank 800.

As shown in Figure 1, the water electrolysis gas generator 100 of the present invention refers to a device or means that performs the function of producing hydrogen and oxygen by electrolyzing water.

The water electrolysis gas generator 100 refers to a device or means that performs the function of producing hydrogen and oxygen by electrolyzing ordinary water.

As shown in FIG. 2, the water electrolysis gas generator 100 of one embodiment receives power from the control device 700, determines the status using various sensors, and generates water electrolysis gas containing a mixture of hydrogen and oxygen. The device includes a water tank 110 for storing water, an electrolysis tank 112 that receives water stored in the water tank 110 and electrolyzes it, and the water tank 110 and the electrolysis tank 112. An on-off type solenoid valve 111 configured between the flashback prevention mixed combustion gas generator 200 and the on-off type solenoid valve 111 capable of blocking the generated mixed gas, and the amount of water supplied to the electrolysis tank 112. A water level sensor 113 for measuring, a water electrolysis gas collection tank 115 for collecting the water electrolysis gas of hydrogen and oxygen produced by electrolyzing water in the electrolysis tank 112, and the water electrolysis gas collection tank It may include a pressure sensor 114 installed at 115 to measure the pressure of the water electrolysis gas.

In addition, the water electrolysis gas generator 100 includes a device including wind power or solar power to obtain initial starting power, and heat generated when water is electrolyzed in the electrolyzer 112. It consists of a temperature sensor that detects and a ventilation fan or other cooling device for heat dissipation based on the output of the temperature sensor.

And when the internal pressure of the water electrolysis gas generator 100 becomes 4 kg/cm2 by the installed pressure sensor 114, the control device 700 controls the power supply of the electrolyzer 112 to reduce the pressure. The amount of electrolysis is adjusted so as not to exceed it, and the water electrolysis gas generated in this way is supplied to the flashback prevention mixed combustion gas generator 200 through a filter that filters moisture.

The water electrolysis gas opened by the on-off solenoid valve 111 passes through the flashback prevention mixed combustion gas generator 200 containing a liquid substance, and the flashback prevention mixed combustion gas generator 200 prevents backfire. It contains reducing substances to reduce the production of NOx (nitrogen oxides) and includes a water level sensor to detect the appropriate water level and a solenoid valve to supplement and supply liquid according to the results measured by the water level sensor. It includes a water supply device (not shown).

The water electrolysis gas generator 100 configured as described above supplies the water stored in the water tank 110 to the electrolyzer 112 by using the solenoid valve 111 and measures the amount of water in the electrolyzer 112. A water level sensor (113) is installed to ensure that an appropriate amount of water is supplied. When the supply of water is completed, the control device 700 supplies the power required for electrolysis to the electrolyzer 112 to start electrolysis. The water electrolysis gas electrolyzed in the electrolysis tank 112 is collected by the water electrolysis gas collection container 115, and the control device 700 uses a pressure sensor 114 installed in the water electrolysis gas collection container 115. By controlling the control device 700 so that the pressure of the water electrolysis gas does not exceed a certain pressure, it is operated safely.

The flashback prevention mixed combustion gas generator 200 of the present invention receives the water electrolysis gas produced from the water electrolysis gas generator 100 to prevent flashback, which is a phenomenon in which a flame flows back, and at the same time suppresses the production of nitrogen oxides. It refers to a device or means that performs the function of receiving a liquid containing a reducing agent and supplying water electrolysis gas containing a reducing agent and saturated water vapor to the mixed gas supply device 400.

As shown in Figure 3, the flashback prevention mixed combustion gas generator 200 of the present invention includes a reducing agent tank 202, a solenoid valve 211, a water level sensor 212, a safety valve 213, and a temperature maintenance device 214. It consists of:

The flashback prevention mixed combustion gas generator 200 supplies a reducing agent tank 202 containing a reducing agent for reducing various exhaust gases and the stored reducing agent to the flashback prevention mixed combustion gas generator 200 through a solenoid valve 211, A water level sensor 212 is installed in the flashback prevention mixed combustion gas generator 200, so that an appropriate amount of reducing agent is always supplied.

In addition, the flashback prevention mixed combustion gas generator 200 is equipped with a safety valve 213 that automatically discharges the internal gas when the low-pressure gas standard is exceeded and a temperature maintenance device 214 that maintains the temperature constant. , the temperature maintaining device 214 includes a temperature sensor.

The water electrolyte gas containing a reducing agent and saturated water vapor that has passed through the anti-backfire mixed combustion gas generator 200 is a gas containing a reducing agent to suppress the production of nitrogen oxides (NOx) and the production of CO and HC, and hydrogen and oxygen are divided into two: The detonation state of 1 is changed to a released gas and supplied to the internal combustion engine 500 through the heterogeneous gas supply device 400.

The water electrolysis gas that passed through the flashback prevention mixed combustion gas generator 200 electrolyzed water to create hydrogen and oxygen, so the ratio of hydrogen: oxygen = 2: 1, and hydrogen and oxygen are mixed at 2: 1. The detonated gas is called a detonation, and ignition can occur due to minute static electricity or sparks. The combustion speed of a mixed gas of hydrogen and oxygen or air is greater than that of hydrocarbons, and at 1 atmosphere of pressure, it is about 2.7 m/sec for a hydrogen-air mixed gas (about 40 vol% oxygen) and about 9 m/sec for a hydrogen-oxygen mixed gas. (Hydrogen: about 70 Vol%). Therefore, a device to prevent this is absolutely necessary.

Therefore, in the present invention, a device is constructed in which a mixed gas of hydrogen and oxygen passes through a flashback prevention mixed combustion gas generator 200 containing a liquid substance as described above, and the saturated water vapor of the liquid contained while passing through this device is constructed. It mixes with hydrogen and oxygen, interfering with the spontaneous chemical reaction of hydrogen and oxygen.

In this way, the water electrolyte gas containing the reducing agent and saturated water vapor contained in the flashback prevention co-fired gas generator 200 is released from the detonation state, eliminating the risk of explosion, and is absorbed into saturated water vapor when acting as fuel for an internal combustion engine. The included ingredient, carbon, has the effect of increasing the amount of heat.

As shown in Figure 3b, the flashback prevention co-fired gas generator 200 of the present invention includes a sealed container 210 made of a metal material to accommodate a liquid 201 containing a reducing agent, and the container 210 At the top of one side, there is an inlet pipe 220 that extends to the inside of the container 210 and through which the mixed gas of hydrogen and oxygen generated from the outside flows in, and at the top of the other side of the container 210 is the inside of the container 210. There is a discharge pipe 230 that extends to discharge the mixed gas of hydrogen and oxygen.

Here, except for some reducing substances, the first function of the liquid, which is water, is the water electrolysis gas generator 100 installed to the outside by the liquid when the flame generated from the internal combustion engine proceeds in the direction of the container 210. It has the function of blocking backfire.

The second function is that saturated steam containing a reducing agent contained in the liquid (in the present invention, it is not limited to a specific type and may include a plurality of reducing agents as needed) is applied to the pressure generated in the water electrolysis gas generator 100. The exhaust gas discharged at this time consists of hydrogen (H ₂ ), oxygen (O), oxidizing agent, and H ₂ O.

In this way, the flashback prevention mixed combustion gas generator 200 serves to lower the combustion chamber temperature of the internal combustion engine through the liquid 201 containing a reducing agent, thereby suppressing the generation of thermal NOx, CO, and HC. In addition, the flashback prevention co-fired gas generator 200 serves as an exhaust gas suppression pre-processing system that prevents flashback and creates safe fuel while suppressing the generation of thermal NOx, CO, and HC.

The technical characteristic of the reducing agent stored in the reducing agent tank 202 of the present invention is that it contains liquid zeolite and ammonia.

In the present invention, liquid zeolite and ammonia can be used individually or in combination.

Preferably, it is very effective to include 50 to 150 parts by weight of ammonia per 100 parts by weight of liquid zeolite.

The reducing agent containing 50 to 150 parts by weight of ammonia per 100 parts by weight of such liquid zeolite causes adsorption and catalytic reactions to provide high concentrations of hydrogen (H ₂ ), oxygen (O 2 ), and H ₂ O (water vapor).

The above-mentioned reducing agent can have the effect of preventing the generation of pollutants (SOx, NOx, etc.) (SOx can be generated from sulfur contained in mixed fuel) by further mixing essential oils.

Preferably, the reducing agent is effective by mixing 0.1 to 2 parts by weight of essential oil with 100 parts by weight of zeolite.

The above-mentioned essential oil refers to oil extracted from natural plants such as plants, herbs, medicinal herbs, etc., and can be used by mixing with water and diluting as necessary.

Methods for extracting the above-mentioned essential oil include steam distillation, solvent extraction, compression, and supercritical carbon dioxide extraction for a mixture of plants, herbs, and herbs, which are raw materials for extracting medicinal solutions.

As an example of the method for extracting the above essential oil, in the case of solvent extraction, a mixture of plants, herbs, medicinal plants, etc., which are raw materials for extracting a medicinal solution, is mixed with a volatile solvent such as alcohol, benzene, ether, hexane, etc. Chemical solutions can be extracted at relatively low temperatures using volatile solvents.

This solvent extraction method has the characteristic of increasing the yield of essential oil.

The above-mentioned natural plants refer to fruit materials such as lime, fragrant tree leaves such as pine needles, or various types of herbs that are fragrant plants.

The above-mentioned herbs include clove, lavender, peppermint, lemon balm, basil, chamomile, jasmine, rosemary, borage, passionflower, clary sage, arnica, and spatium.

The essential oil of the present invention suppresses the generation of thermal NOx, which is a common air pollutant, and has the function of suppressing the generation of SOx, which may be generated later by combustion with mixed fuel.

It is better to include 0.01 parts by weight, 0.001 to 0.01 parts by weight of sulfur (S), and 0.3 to 1.5 parts by weight of copper (Cu).

The present invention may include a strength-enhancing additive to increase the strength of the carbon steel material described above.

The above-described strength-enhancing additives can be mixed in an amount of 0.001 to 0.01 parts by weight based on 100 parts by weight of iron (Fe).

The strength-enhancing additive of the present invention is 1 to 10 parts by weight of calcium sulfate, 1 to 5 parts by weight of illite, 2 to 10 parts by weight of zinc, 1 to 5 parts by weight of potassium, 1 to 5 parts by weight of cobalt, per 100 parts by weight of sodium hydroxide. It means that it is formulated by mixing 1 to 3 parts by weight of graphite.

The strength of the container using carbon steel containing the above-described strength-enhancing additives is increased by about 1.2 to 1.5 times compared to the case where the strength-enhancing additives are not included.

The present invention can further increase the heat resistance of the container and prevent condensation of the generated co-fired gas by further including a natural functional additive in addition to the strength-enhancing additive described above.

The above-mentioned natural functional additives may contain 0.1 to 0.5 parts by weight based on 100 parts by weight of sodium hydroxide.

The above-mentioned natural functional additive is a composition extracted by mixing 100 to 30 parts by weight of Gwakhyang, 10 to 30 parts by weight of Jeolgukdae, 80 to 120 parts by weight of Hwangjeong, 10 to 30 parts by weight of Banha, and 50 to 80 parts by weight of Sokdan with 100 parts by weight of Pagoji. it means.

The method of extracting the above-mentioned natural functional additives is to add 1000 parts by weight of 75-85% [mass%] ethanol to 100 parts by weight of the above mixed raw materials, reflux and extract for 2-4 hours, and depressurize the filtrate using a rotary evaporator. , it can be extracted by concentrating.

This extract can be extracted in powder form in an amount of 5 to 25 parts by weight based on 100 parts by weight of the mixed raw materials, and it is preferable to add the extract in powder form.

The present invention performs the function of maintaining the supply pressure of the water electrolysis gas supplied to the mixed gas supply device 400 constant by adding a surge tank 800 to the flashback prevention mixed gas generator 200.

As shown in FIG. 3C, the surge tank 800 is connected to the discharge pipe 230 to introduce water electrolysis gas, and the surge tank 800 supplies the water electrolysis gas to the mixed gas supply device 400 at equal pressure. It is supplied to prevent poor starting of the internal combustion engine 500 due to pressure changes, engine shutdown, and irregular operation of the starting output (RPM).

It is preferable that a check valve 231 to block backflow is installed in the discharge pipe 230 described above.

It is preferable that an electromagnetic valve 811 that turns on/off the pipe 810 is installed in the middle of the pipe 810 that supplies the water electrolysis gas from the surge tank 800 to the mixed gas supply device 400, and the surge tank ( 800) is preferably installed with a pressure sensor that provides a driving source for the solenoid valve 811.

Meanwhile, it is clear that water electrolysis gas is environmentally friendly and is a clean energy source that does not contain carbon dioxide (CO ₂ ), but if an internal combustion engine is operated using only water electrolysis gas, a lot of hydrogen is needed to supply the amount of heat required by the internal combustion engine. It is obvious that a large amount of water must be decomposed.

Additionally, this result is similar to hydrogen fuel cell power generation, which uses a lot of energy (electricity) for electrolysis and ultimately produces expensive electricity.

Therefore, the present invention provides fossil fuel to the mixed gas supply device 400 through the mixed fuel supply device 300 to produce hydrogen (H ₂ ), oxygen (O 2 ), and oxygen (O 2 ) provided by the water electrolysis gas generator 100. An effective method is to provide a mixed gas by mixing H ₂ O (steam) (hereinafter referred to as mixed combustion gas) fuel with a mixed fuel, which is a fossil fuel, and provide the mixed gas to an internal combustion engine.

The mixed fuel supply device 300 of the present invention preferably uses organic compounds as fossil fuels, and the organic compounds are liquid compounds composed of carbon, hydrogen, nitrogen, oxygen, etc., and highly volatile and flammable organic compounds such as ethanol.
