  By the way, the carbon dioxide is recovered and the press-fitting method into the deep underground reservoir requires a great deal of labor to recover the carbon dioxide separation and sorting cost in advance and the cost for the equipment to be transported to the destination. In addition, a large amount of discharge and separation / recovery in a small facility are expensive and have not been put to practical use.

  The present invention is to collect and recover carbon dioxide / water gas from carbon, hydrogen, and oxygen, and immediately use the carbon / hydrogen / oxygen molecules as regeneration energy. Furthermore, the separation and recovery method can be used for the purpose of creating new fuel as renewable energy by repeating it multiple times in succession, so environmental conservation technology that combines fundamental suppression of carbon dioxide emissions and protection of carbon-based fuel resources. The purpose is to provide.

  In the method for separating and recovering carbon dioxide / water exhaust gas according to the present invention, exhaust gas released by combustion is passed through a process under high temperature and high pressure to cause molecular separation into a carbon group, a hydrogen group, and an oxygen group. All exhaust gases are characterized by molecular free recovery of carbon dioxide molecular composition and aqueous exhaust gas composition during the process until the exhaust treatment after combustion of carbon-based fuel.

  At the same time, if the carbon, hydrogen and oxygen groups recovered under high temperature and high pressure are reused under the same conditions, a clean regenerative energy effect and efficiency can be obtained. In addition, if a plurality of continuous recoveries of this technology are used, it is also characterized by significant exhaust gas suppression and fuel consumption reduction effects.

  In the method and apparatus for separating and recovering carbon dioxide and aqueous exhaust gas according to the present invention and the re-burning method, the emission reduction of environmental pollutants is greatly simplified by the mechanism of high temperature and high pressure during combustion. And aqueous exhaust gas can be continuously recovered and re-burned.

  At the same time, because the recovery method is a method of molecular dissociation of carbon, hydrogen, and oxygen, a new caloric effect is created in order to make use of it as a regenerative energy. Can be suppressed. This results in further thermal efficiency and an effect of suppressing basic fuel, and as a result, the cause of carbon dioxide emission is suppressed. That is, carbon dioxide can be reduced by 50% or more together with the fuel reduction effect by using renewable energy as carbon fuel after suppressing the recovery of carbon dioxide in the exhaust gas.

FIG. 1 is an example of an apparatus for generating high temperature and high pressure related to the method for separating carbon dioxide and water gas according to the present invention, and an elevation view thereof is shown as a perspective view. 2, 4 and 8 in the figure are exhaust ports through which carbon dioxide / water gas exhaust gas passes. 3 in the figure is a normal carbon fuel combustion chamber. 5 and 7 in the figure are gas compression chambers for the method for separating and recovering carbon dioxide / water exhaust gas after combustion. This compression chamber is a gas separation chamber that separates and recovers carbon dioxide and water gas from carbon molecules / hydrogen molecules and oxygen molecules. Reference numerals 10 and 11 in the figure are basic technical methods for achieving the necessary high temperature and high pressure conditions for causing the high temperature condition and high pressure condition necessary for the present invention in the gas separation chamber. The compression chamber 9 in the figure becomes a combustion chamber in which pure carbon groups, hydrogen groups, and oxygen groups are separated and immediately re-burned as regenerated energy. 1B in the figure plays the role of complete combustion that promotes the regeneration energy combustion. 2 in the figure is the basis for the amount of heat generated by the combustion method, which is one factor of the present technology. The present invention proves the energy required for molecular separation of carbon dioxide gas into a carbon group and an oxygen group under high temperature conditions of 1400 degrees. The required temperature is obtained by the theoretical combustion temperature of oxyfuel combustion and air combustion. In other words, when the external conditions of oxyfuel combustion are changed from normal combustion, a calorific temperature of about 50% is obtained. This is the basis for a method in which the effective exhaust gas also increases in proportion to the temperature. Fig. 3 shows an example of the verification results and explanation. The result of measuring the ambient ambient temperature in Fig. 3 shows about 1450 degrees. The experimental nozzle was burned with a commercially available two-fluid (fuel and primary air) nozzle. Air combustion alone could not record more than 1000 degrees. This experimental method is a measurement of the separation chamber No. 5 in FIG. The fuel is the result of using the new oxygen-containing fuel described in Patent Document 2. This temperature is accumulated in the exhaust gas as shown in the figure 7.9 to amplify the amount of radiant heat.

  In the present invention, the carbon group, hydrogen group, and oxygen group of carbon dioxide / water gas are separated and recovered by using a mechanism that always keeps a certain amount of radiant heat using the combustion heat of the carbon-based fuel. It is characterized by a method in which molecular separation is performed by using the amount of radiant heat generated by carbon dioxide and aqueous exhaust gas by raising the temperature and pressure conditions necessary for stripping and recovery.

  Aqueous exhaust gas is usually used in combustion technology to cause a water-gas reaction shift with carbon from 1100 to 1200 degrees at high pressure, and carbon dioxide gas is carbon group and oxygen at 1400 degrees and above at high pressure. There is a scientific thermal condition that molecules are peeled off based on the condition, and they can be separated if the conditions are aligned. However, this technology has not been used for a new heat source. However, the apparatus of the present invention is realized without using an external heat source in the basic heat storage and utilization system of the exhaust gas from which the energy of the high temperature condition and the high pressure condition by the new heat source is discharged. The heat source energy can be secured by retaining the heat at a constant high temperature by using a ceramic material or a steel material as a heat-resistant material that maintains high heat throughout the apparatus shown in the drawing. For that purpose, it is possible in the separation chamber under the high temperature and high pressure conditions of 3, 5, 7, and 8 in the figure. As a result, the temperature of the separation chamber reaches 1400 degrees. At this target temperature, the separation and recovery of carbon dioxide gas easily proceeds, and further radiant heat utilization can be obtained from 1B by reusing combustion as regenerated carbon fuel energy.

The exhaust gas separation and compression chamber under high temperature and high pressure is proved by Boyle-Charles' law and oxy-combustion theory. In basic thermodynamics, exothermic reaction heat and endothermic reaction heat have been used as radiant heat, but this method theoretical value does not include external variables.
In principle, it is important that the basic technology necessary for the apparatus of the present invention is to efficiently compose a high temperature. It is possible to raise the combustion temperature by arranging the combustion chambers in series.

  In the embodiment of the present invention, FIG. 1 of the present invention is installed in a combustion burner flame outlet for discharging carbon dioxide gas. If the amount of input fuel is adjusted by monitoring the temperature in the number 3.5.7.9 divergence chamber in the figure, the molecular divergence temperature and amount are adjusted according to the fuel used. Increasing the mass of the combustion temperature and the amount of radiant heat will be described below.

  When the molecules are dissociated, naturally the endothermic reaction appears as a thermodynamic equation. In short, since heat is deprived in order to separate the exothermic bond chemical formula, the conventional technology method requires new heat energy for separation and recovery of exhaust gas, and does not meet the cost that can be used as the law of thermodynamic energy. The present invention shows that if the difference between the endothermic reaction and the exothermic reaction is large, an economic effect can be obtained. The rationale is explained below.

  As shown in FIG. 2, it has been found from theoretical values that the thermal effect is increased by 40% or more when compared with air combustion and oxyfuel combustion. However, this is an example that requires a precondition of 40% or more for oxygen supply. Therefore, when the present invention uses a fuel containing an oxygen group as in Patent Document 2, by providing this separation chamber, the exhaust gas tends to stay, and it is easy to reach a high temperature exceeding 1300 degrees. Was obtained. As a result, by providing the next divergence chamber, the high temperature exhaust gas stagnation was promoted. As a result, the molecular divergence of carbon dioxide and aqueous exhaust gas and the recombustion result were obtained. As a result, an exhaust gas temperature of more than 1600 degrees and radiant heat were obtained simultaneously. The academic basis is proved below.

  The reason for this is that the high temperature and exhaust gas utilization efficiency of air combustion and oxyfuel combustion are due to oxygen, but the largest variable in actual combustion efficiency is presumed to be due to nitrogen predisposition as the cause of heat generation and temperature decrease . When the experiment is repeated, the molecular composition immediately after the separation chamber is such that the carbon group, the hydrogen group, and the oxygen group are immediately present. Individual observations are impossible if the molecule is dissociated in the case where the molecule is 1400 degrees or more, but it is understood that it is easy to guess that carbon groups and oxygen groups will immediately bond and burn, and hydrogen and oxygen groups will bond and burn. it can. The proof can be proved by increasing the temperature by increasing the separation chamber. The practical availability will be explained below.

  In the experimental example of the present invention, the heat generation temperature, and the amount of radiant heat, the high temperature and the amount of radiant heat can be controlled by the shape and number of exhaust gas divergence chambers. This can be easily done by changing the shape of the room according to the heat consumption and temperature of each industry, based on the same principle as the traditional charcoal huts and Seto ware climbing kilns. An example is given below.

  For example, when it is used for industrial waste combustion, there is a utility value that can melt the waste at a temperature of 1200 degrees or more, but in those cases, the desired temperature and heat quantity can be supplied in 2.3 separate rooms. In addition, when using high heat related to steel making of ingots, it is possible to use high heat treatment of 1600 degrees or more and heat of renewable energy by further increasing the separation chamber.

FIG. 1 shows an example of the overall shape of a combustion system that produces high-temperature and high-pressure conditions and the shape of the molecular separation chamber, which enables the molecular separation method of carbon dioxide gas and water gas exhaust gas of the present invention. is there.

  Fig. 2 shows scientific experimental data on the grounds for proving the molecular dissociation conditions of carbon dioxide gas and water gas in Fig. 1 due to high temperature and high pressure. This data is the temperature comparison data of pure oxygen combustion and air combustion described above. Air combustion is actual combustion data, which is about 47% lower efficiency than pure oxygen combustion. This data is proof that the amount of fuel heat under the actual thermodynamic Hess law varies greatly depending on the preconditions of external variables. This shows a variable curve in which the radiant heat temperature and the amount of heat are changed by changing the usage method and usage conditions of the same amount of fuel. The temperature required for molecular separation of carbon dioxide gas according to the present invention is about 1400 ° C., but observation data shows that it cannot be realized by air combustion. However, the experimental data on which the radiant heat reaction of 1400 degrees or more was obtained by causing the radical reaction combustion in the present invention to cause the radical reaction combustion in the present invention, and the radiant heat reaction of 1400 degrees or more is proved as follows. .

  3 in the figure is actual measurement data obtained by temperature measurement reaction of the above-mentioned radical thermal reaction. The measurement data indicates 1531 degrees. This temperature is a temperature that is not normally emitted by air combustion, but can be said to be a calorific temperature at which pure oxygen combustion can be proved by utilizing the regeneration energy after molecular separation of the present invention. Below are the drawings and the transition of radiant heat by scientific reaction and temperature rise by actual use.

  In the following, we will verify whether a new amount of heat and temperature can be generated efficiently by changing the variable conditions of the combustion environment premise against the amount of heat of the basic fuel. The method of raising the combustion temperature by setting the combustion chamber in a multi-stage manner as shown in Fig. 1 has been proven by the method of raising the combustion temperature of ancient Japanese climbing kilns. However, as shown in FIG. 2, if the conditions for reaching a high temperature of 1400 ° C. are provided in multiple stages like the molecular separation chamber in FIG. 1, the temperature can be further increased. Therefore, it is a feature of the present invention that the heat radiation generated from normal combustion is advanced to a higher temperature by using a porous material and continuously using a multistage combustion chamber. As a result, separation of carbon groups and oxygen groups occurs due to carbon dioxide gas molecule separation occurring at over 1400 degrees, and it is considered that explosion of the in-situ regeneration energy combustion occurs under high temperature and high pressure. Under a chemical reaction under these conditions, since a carbon group and an oxygen group readily undergo a collision combustion, it is easy to generate a pure oxygen-enriched combustion state. The high-temperature heat and radiant heat proved in Fig. 2 show that there are no obstructions caused by air combustion such as nitrogen in this combustion condition, so both the radiant heat and the endothermic reaction due to molecular separation of the conventional calorie exceed the exothermic reaction heat. A combustion effect occurs. Figure 3 shows an atmospheric temperature of 1531 ° C, which is considered to be a proof of the chemical reaction.
