Description

Fuel Emulsion Mixing Device For Boiler Or Internal Combustion Engine}

The present invention is a fuel emulsion mixing apparatus for boilers and internal combustion engines, and more specifically, a fuel emulsion mixing apparatus of a completely new method that realizes complete combustion of fuel using CAVITATION.

The general fuel emulsion mixing device refers to a combustion promoting induction device that mixes and supplies fuel and water to a combustion engine at a constant ratio. Until now, an emulsifier (artificially charged chemical substance) is added to a driving device and mechanical rotational power is used. This has been used mainly.

Operation of the unit is the pressure of the fuel incoming to the compensating valve 4, as shown in FIG. 1 ^{P1 (12.7Kg / m 2 - 20Kg} / m 2) the compensation valve (4) a small adjustment of the lower screw (A -1) is adjusted to the pressure P2 (2.1 Kg / m ² ) in the chamber (5), and the cavity (CAVITATION) in the chamber (5) is generated, and the force exerted from the control by the precise control (SHEARING) STRESS: 800-1000 Kg / m ² ) using the heated temperature to grind and superfine the irregular fossil fuel and adjust the size of the water particles to be mixed from the water supply valve 4-1 shown in FIG. Water into the cavity (CAVITATION) in the chamber (5) is first homogenized and emulsified and mixed.

The mixed homogenized fuel passing through the chamber (5) is transferred from the pump (8) to the second chamber (13) through the emulsion fuel transfer pipe (7), and the second re-homogenous mixture is mixed through the discharge pipe (14). Fuel transferred to the combustion engine is burned by a burner 50-100 It is atomized into ultra-sized particles of size and finally reaches complete combustion.

However, the conventional technique is a situation that does not fundamentally solve the cause of environmental pollution by adding an emulsifier, which is a chemical substance in order to facilitate the mixing of water and oil with different physical properties.

In addition, large-capacity boilers and internal combustion engines require the installation of several emulsifiers in proportion to their capacity, which requires increased equipment costs and a large installation area.

A device that innovatively compensates for the problems caused by the conventional technology is a method using CAVITATION.

The present invention is a device developed to fundamentally solve the problems presented in the prior art, and simply generates a cavitation without a driving part due to the pressure difference by simply operating the compensation valve 4 in front of the chamber 5. It is a device that emulsifies and mixes fuel, so it is possible to supply fuel from a small capacity to a large-capacity combustion device according to the size of the pipe, and the initial investment cost is very low compared to the conventional technology, the recovery period is short, and the installation area is large. There is a small advantage and water and oil are not separated for a long time, so they can be stored in auxiliary tanks and supplied to multiple boilers.

In order to further reduce SOx and NOX, lime water injection valves (4-2) and ammonia water injection valves (4-3) are installed on the left and right sides of the water supply valves at the bottom of the compensation valve (4) to minimize the main causes of environmental pollution. The purpose is to increase the amount of water in the mixture of water and oil to achieve energy savings.

In order to achieve the object as described above, the fuel emulsion mixing apparatus for the boiler and the internal combustion engine according to the present invention has a pressure (P1: 12.7Kg / m ² -20Kg / m ² ) of the front end of the compensation valve (4). ) Cavitation is generated in the chamber 5 by constantly adjusting the pressure (P2: 2.1 Kg / m ² ) transmitted to the chamber 5 by the adjusting screw A-1 at the bottom, By using the force (SHEARING STRESS) to crush the irregular fossil fuel in the chamber (5) the water flowing through the water supply valve (4-1) at the bottom of the compensation valve (4) and the oil flowing through the flow meter (1), Constant cavitation with ultra-fine particles and controlling the size of water particles

It is mixed homogeneously in (CAVITATION).

In order to create a constant cavitation, the adjustment screw (A-1) shown in Figure 4 below the compensation valve (4) must be adjusted by the cavitation formula (1) of the flow pressure difference. This process is the primary emulsion mixing process, and the oil-mixed fuel passed through the primary process is divided into 2, such as a pipe (7), a pump (8), an auxiliary valve (11), a compensation valve (12), and a chamber (5). Passing the second step leads to better emulsion mixing. After the first and second processes, the water particles surround the oil particles, and when viewed under a microscope of 400 times, it is confirmed that they are well mixed.

When this well emulsified fuel is combusted through the burner of the combustor, the oil particles surrounding the water particles are heated in the combustion chamber to explode and explode, crushing the oil particles into thousands of branches, bringing the SOX closer to complete combustion. Adding lime water to reduce the effect is better, and NOX can maximize the effect of reducing air pollution and reducing fuel by spraying ammonia water.

A) Effect of complete combustion

In general, the creation and control of CAVITATION of the fluid is very difficult, but the emulsion mixing device generates and precisely controls the cavitation using a compensation valve, a chamber, a pump, and other senses. Using this powerful force (SHEARING STRESS: 12,000 TO 15,000PSI), irregular fossil fuels are pulverized and ultrafine, and the water and oil are mixed in a constant ratio while controlling the size of the water particles to be mixed efficiently and efficiently. Allow combustion to take place.

Fuel homogenized with this emulsification mixing unit is 50-100 by burner It is sprayed with fuel of the size and sprayed into the flame in the flame chamber to burn high temperature.

The water particles of the sprayed fuel are rapidly heated, overheated, expanded more than 1600 times, and evaporated explosively (MICRO EXPLOSION), causing the oil surrounding the water particles to scatter in all directions, causing secondary ultrafine particles. The surface area is increased to improve the cross-sectional area of contact with air, resulting in very good combustion resulting in faster combustion speeds, longer flame lengths, and color changes from dark red to bright blue.

As described above, the continuous microexplosion caused by the water particles becomes more intense, and the entire water particles instantly explode and disappear. It is intensively formed by phenomena.

Turbulent diffusion combustion in the fire chamber increases the heat transfer coefficient, increases the thermal emissivity due to the increase in water gas (CO ₂ H ₂ O), and drastically reduces the EXCESS AIR due to this combustion phenomenon, and produces strong convection. Generation and nearly complete combustion while suppressing local hot spot generation.

B) Effect of preventing air pollution

THERMAL NOX, which produces highly acidic hazardous substances, is affected by the flame temperature, its structure, and the combustion residence time of the fuel. Therefore, the homogeneous mixing of water and oil in the optimum state causes micro-explosion, and the heat residence time with the effect of temperature equalization and temperature reduction in the local high temperature zone (temperature variation in the firebox) by the uniform heat transfer of the endothermic water gasification reaction By shortening and complete combustion, the optimum flame structure can be achieved and NOX can be reduced.

Being oxidized to

(The above reaction is an endothermic reaction that absorbs heat from the environment.)

The combustion process always results in incomplete combustion, in which intermediate products (eg NO) are released and become contaminants.

-FUEL NOX, the main pollutant together with THERMAL NOX, is mainly affected by the air cost of combustion. Therefore, it is effective to reduce the excess air ratio by 20-30% while suppressing the initial NO production by approaching the complete combustion of the secondary chain microexplosion furnace (ultrafine gasification) of the mixed fuel optimally homogenized by this emulsifier. can do.

Fossil fuels are impure and contain elements other than carbon or hydrogen (metal elements such as sulfur, nitrogen, and vanadium), causing pollution.

-To suppress the production of sulfuric acid (H ₂ SO ₄ ), which is a strong acid and corrosive harmful substance, it is burned with low sulfur use, low combustion temperature and low excess air ratio.

Oxidation

- causing corrosion and combustion chamber insulating surface can suppress the fusion material of V ₂ O ₅ (vanadium pentoxide) and dust oxidize the V ₂ O ₅ as the release of a melting point less easily fused by a low excess air ratio combustion with a complete combustion of the fuel have.

The oil homogenized with water by this emulsifier does not separate oil and water for a long time, so it is possible to store the homogenized fuel in auxiliary fuel tank and supply it to several boilers. It can also be applied to food, chemicals, and paint fields that require mixing.
