Description

Water-mixed combustor for complete combustion {THE APPARATUS BURN AFTER MIX OIL AND WATER}

The present invention relates to an oil-water combustion apparatus for burning a mixture of water and oil.

As a research theory is known that the combustion efficiency is better when mixing water and oil than burning only oil, techniques for commercializing this research are being developed.

The theory is that when the oil surrounding the water particles is burned, the water particles are vaporized by the conduction of heat, and the vaporized water vapor increases atomization and diffuses the oil layer, causing the complete combustion of the oil. To cause.

In addition, at a high temperature, water (H 2 O) acts as a supporting agent by causing a continuous radical reaction liberated by oxygen (O), hydrogen (H), and hydroxyl (OH).

That is, at high temperature, water vapor decomposes to produce hydrogen radicals, and hydrogen radicals combine with oxygen molecules to form oxygen radicals and water.

Oxygen radicals are combined with hydrogen molecules to form hydroxyl radicals and hydrogen radicals.

In addition, hydroxyl radicals combine with hydrogen molecules to form water and hydrogen radicals.

In addition, water vapor and hydrogen combine to produce water and hydrogen radicals.

This is shown in the scheme below.

① Equation ...... 2H + O2 → O + H2O: Continuous reaction

② ...... H2 + · O · → · OH + H: continuous reaction

③ Formula ...... · OH + H2 → H2O + H ·: Continuous reaction

④ Formula ...... H2O + H2 → H2O + 2H: Continuous reaction

As the above research theories are known, efforts have been made to commercialize them, but they have not been commercialized.

The main reason for this is the lack of a stable combination of water and oil, the large size of the combustion equipment (equipment), the high capital investment and the inefficiency in energy efficiency.

In Korean Patent Publication No. 95-1407 and Publication No. 96-13612, water is prepared by mixing and stirring a surfactant having a HLB value of 3 to 4, a nonionic surfactant composed of water and polyvinyl alcohol, heavy oil and waste oil at a constant ratio. Has been proposed to produce an emulsion fuel using waste oil as a raw material by dispersing it into fine particles.

In addition, Korean Patent Publication No. 99-64753 discloses water particles by mixing a surfactant having a HLB value of 4 to 5 with water to make an emulsifier, and then mixing light oil, heavy oil, water, and the emulsifier at a predetermined ratio. Techniques for producing emulsion fuel oil by crushing into fine particles of about 0.5 ~ 5㎛ has been proposed.

However, the above-described prior art prepares a mixture by mixing oil, water and an emulsifier in a predetermined ratio, and then stirs the mixture in a tank with a stirrer to crush and emulsify the water contained in the fuel oil into fine particles. It is a method to use as fuel in a state where water is dispersed.

In order to use the above method, there was a problem that excessive facility investment was required.

In addition, even if the water is dispersed in the form of fine particles by using an emulsifier, it is only a temporary, it has not been commercialized because the emulsified state is not maintained for a long time.

As a technology to solve this problem, as in Korea Patent Application No. 10-2006-0026937, water and oil to reduce the auxiliary equipment and paper, and to be able to use the emulsion fuel oil directly as fuel without the process of storing and storing Is supplied to the emulsion mixer at an appropriate ratio, and the emulsion mixer receives the supplied emulsion oil and supplies it to the combustion means, while supplying hydrogen and oxygen using hydrogen / oxygen supply means to the combustion means to increase combustion efficiency. Was drafted.

However, even though the above technology is still large and requires a lot of facility investment cost, the combustion efficiency was not commercialized because it did not meet expectations.

Another problem with the prior arts is that they do not meet the economics of having various means for the combustion of fresh water.

The present invention is to solve the above problems, more specifically, it is possible to manufacture a compact and commercially available and economical, to ensure a stable mixing state of water and oil, and to re-burn the gas discharged The purpose is to provide a water-mixed combustion apparatus capable of complete combustion.

Water and oil are vaporized and mixed evenly in the combustion apparatus so that the mixture is fed to the combustion means and combusted.

In addition, the gas generated in the combustion process is to be burned again.

Through this, it is possible to reduce the size of the oil-in-water combustor to be commercially available, to secure economic feasibility, and to obtain excellent combustion efficiency.

The oil-and-water mixed combustion apparatus of the present invention has a mixing space in which water and oil for mixing are introduced through respective pipes, and the mixture of water and oil vaporized in the mixing space is discharged to the outside by the pressure of the mixing space. It has a mixing tank in which a mixture outlet is formed.

It also has a check valve to block the water and oil in the mixing tank from moving in the reverse direction.

The mixing tank is heated so that the temperature in the mixing space is 180 ° C to 250 ° C and the pressure is 10 to 25 bar.

In addition, it has a mixture combustion means for supplying a mixture of vaporized water and oil in the mixing space for combustion.

The mixture combustion means as described above comprises a combustion furnace having a combustion space in which a mixture of supplied water and oil is combusted.

In addition, it is connected to one side of the combustion space has a combustion gas discharge pipe for discharging the gas generated during combustion to the outside of the combustion space.

In addition, a plurality of holes are perforated and have a perforated plate positioned between the combustion gas discharge pipes from the point where the mixture of water and oil passing through the mixing space is ignited to prevent the flame from spreading along the combustion gas discharge pipes.

The apparatus further includes exhaust gas recombustion means for combusting the gas discharged by applying a flame to the gas passing through the combustion gas exhaust pipe.

In the oil-and-water mixed combustion apparatus of the present invention, water and oil for mixing are introduced into the mixing tank through respective pipes, and the mixing tank is heated so that the temperature in the mixing space is 180 ° C to 250 ° C, and the pressure is 10 to It can be set to 25 bar so that oil and water can be vaporized and mixed evenly by heat and pressure.

In addition, the mixture evenly mixed by the heat and pressure as described above is supplied to the combustion means to be burned, and to be burned again with respect to the gas generated during combustion.

Therefore, the oil-and-water mixed combustion apparatus of the present invention is capable of being downsized to a commercially available size, economical, and has a very excellent combustion efficiency.

In the present invention, the mixing tank and the mixture combustion means are connected to the mixture flow pipe so that the mixture in the mixing tank is supplied to the mixture combustion means through the mixture flow pipe, and is further provided with an auxiliary heater for heating the mixture flow pipe. If there is a feature that can ensure the safety, better combustion efficiency.

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

The present invention relates to a mixed flow combustor for combusting a mixture of water and oil.

Therefore, the apparatus of the present invention also has a mixture combustion means 40 which is supplied with a mixture of water and oil and combusts as in the prior art.

Since the mixture combustion means 40 is already known and may be implemented in the same form as a conventional combustion means provided in a boiler or the like, a detailed description of the mixture combustion means 40 will be omitted.

However, an object of the present invention is to provide a structure for commercialization of the flowing water combustion device.

The main reason why the prior art is not commercialized is that the size of the device is not large and economical, it is difficult to ensure a stable mixing state of water and oil, and the combustion efficiency of the mixture is not as expected.

In order to solve this problem, the inventors of the present application have devised a structure in which water and oil are directly mixed in a combustion apparatus, and the mixture is supplied to a combustion means for combustion after long research and efforts.

The oil-and-water mixed combustion apparatus of the present invention has a mixing space 11 into which water and oil for mixing are introduced through respective pipes, and the mixture of water and oil is discharged to the outside by the pressure of the mixing space 11. It has a mixing tank 10 in which the mixture outlet 12 is formed.

It also has a check valve 20 to block the water and oil in the mixing tank 10 from moving in the reverse direction.

In addition, the mixing tank 10 is heated so that the temperature in the mixing space 11 is 180 ° C to 250 ° C and the pressure is 10 to 25 bar.

That is, in the present invention, the water and oil are placed in a space and heated, so that a constant pressure and temperature conditions are created so that the vaporized water and oil are evenly mixed (these states are commonly referred to as "liquid droplets").

The mixing space 11 is preferably such that the shape from the top to the bottom is a rhombic shape, which is excellent in the effect of being evaporated and amplified in the empty space at the top when water and oil are filled in about half of the mixing space 11. Because.

Through experiments, it was found that when the temperature in the mixing space 11 was 180 ° C. to 250 ° C., and the pressure was 10 to 25 bar, water and oil were evenly mixed.

It can be ensured by heating the mixing tank 10 that the temperature in the mixing space 11 is 180 ° C to 250 ° C and the pressure is 10 to 25 bar.

That is, since the tank shape having a space therein is the same as the pressure vessel, when heated, the fluid or gas stored therein expands and the pressure rises. This principle uses this principle. Ascent is more smooth)

Preferably, the mixture outlet 12 is not opened until the temperature and pressure in the mixing space 11 reach the set value, and the mixture outlet 12 is opened when the pressure reaches the set pressure.

This configuration can be ensured by providing a pressure regulating valve at the mixture discharge port 12 or the rear end thereof.

The temperature control can be ensured by allowing the temperature in the mixing space 11 to be sensed and driving the mixing tank heater 30 based on the sensed temperature.

As another method for the temperature and pressure in the mixing space 11 to be within the set range, the size of the mixing space 11, the size of the mixture outlet 12, the amount of water and oil introduced, the mixing tank heater 30 It can also be obtained by setting in advance the degree of heating through.

The reason why the check valve 20 is provided is to prevent backflow of water and oil supplied to the mixing tank 10 due to the pressure acting on the mixing space 11 of the mixing tank 10.

The above-described mixed tank heater 30 may be implemented in the form of an electric heater having a heating element (coil, heating rod, etc.) that is generated by electrical energy, various forms such as having a burner using gas or oil as fuel Can be implemented.

The mixture of water and oil mixed in the mixing tank 10 may be close to the combustion point, but to ensure safety, the mixing tank 10 and the mixture combustion means 40 are connected to the mixture flow pipe 50 and mixed. It is preferable that the mixture in the tank 10 is supplied to the mixture combustion means 40 through the mixture flow pipe 50 so that the mixture is combusted. Discharged and flow into the mixture flow pipe (50) and sprayed)

In addition, at the end of the mixture flow pipe 50, it is preferable to install a spray nozzle for spraying the mixture widely.

In particular, if the end diameter of the mixture flow pipe 50 is 1mm or more, there is a need to install a spray nozzle.

If there is no additional means in the case of having the mixture flow pipe 50 as described above, the mixture via the mixture flow pipe 50 is placed in a condition of low pressure and temperature toward the injection point.

As such, when the temperature and pressure are lowered, the mixing efficiency of water and oil may worsen and combustion efficiency may decrease.

In order to prevent this, it is preferable to further include an auxiliary heater (60) for heating the mixture flow pipe (50).

That is, the mixture flow pipe 50 is heated to prevent the pressure and temperature of the mixture flow pipe 50 from decreasing.

The auxiliary heater 60 may be implemented in the form of an electric heater or a burner (a burner using gas or oil as fuel), such as the mixing tank heater 30.

In addition, it can be implemented in a structure that burns wood to obtain heat.

In addition, the waste synthetic resin may be supplied and combusted, and the heat generated in the combustion process may be implemented in the form of a waste synthetic resin burner installed to be transferred to the mixture flow pipe 50.

Since the waste synthetic resin burner is already well known and applied to various industrial fields, a detailed description of the waste synthetic resin burner will be omitted.

However, since the waste synthetic resin burner requires a considerable time and energy to operate normally, if the waste synthetic resin burner has a form, a means for heating the mixture flow pipe 50 is required until the waste synthetic resin burner is normally driven.

Such means can be implemented in the form of electric heaters or burners that use gas or oil as fuel.

The accompanying drawings show that the gas (LPG, etc.) supplied for driving the mixing tank heater 30 is supplied to and combusted in the combustion furnace 41 of the waste synthetic resin burner to support the normal driving of the waste synthetic resin burner and in the process. The generated heat is shown to be used to heat the mixture flow pipe 50.

The mixture combustion means 40, which is a component of the present invention, has been described as being possible in various forms known in the art.

A plurality of holes (43a) is formed in the perforated and in front of the combustion gas discharge pipe 42 (between the combustion gas discharge pipe 42 from the point where the mixture of water and oil via the mixed space 11 is fired). It is preferably implemented in the form having a perforated plate 43 is positioned to prevent the flame from spreading along the combustion gas discharge pipe 42.

That is, the perforated plate 43 allows the mixture to be burned more completely.

On the other hand, the present invention also has an object to ensure that the mixture of water and oil is a complete combustion.

In the structure as described above, even if the gas discharged from the center portion of the perforated plate 43 is completely burned, the gas discharged near the edge of the perforated plate 43 may be incomplete combustion.

Therefore, the gas discharged toward the combustion gas discharge pipe 42 near the edge of the perforated plate 43 is preferably re-injected into the combustion furnace 41 of the mixture combustion means 40 and combusted again.

In order to achieve this, in implementing the combustion gas discharge pipe 42, the combustion gas discharge pipe 42 may be implemented in the form of a double pipe having an inner tube 42 a and an outer tube 42 b.

At this time, any one of the inner tube (42a) is located in the center portion of the perforated plate 43 so that the gas discharged from the center portion of the perforated plate 43 is introduced, the introduced gas is discharged to the outside.

In addition, one of the outer tubes 42b is positioned near the edge of the perforated plate 43 and the other is connected to the combustion furnace 41 so that the gas collected through the outer tubes 42b is the combustion furnace 41. To be put back in.

When the plurality of holes 43a drilled in the perforated plate 43 in the above description are tapered holes having a smaller drilling area toward the combustion gas discharge pipe 42 as shown in FIG. The effect of making is even better.

The outer tube 42b described above is connected to the air injection means for blowing air into the combustion furnace 41 through the air injection blower 71 so that one side of the outer tube 42b is connected to the combustion furnace 41, When the suction force by the air injection blower 71 is applied to the outer tube 42b, the incomplete combustion gas is smoothly re-injected into the combustion furnace 41 of the mixture combustion means 40.

Even with the above configuration, unburned gas may be generated via the combustion gas discharge pipe 42.

Therefore, for complete combustion, the exhaust gas recombustion means 44 may be provided to apply the flame to the gas generated while the mixture of water and oil is combusted so that the exhaust gas is combusted.

The structure in the accompanying drawings is a structure in which a flame is applied to the gas passing through the combustion gas discharge pipe 42.

The exhaust gas recombustion means 44 may be implemented in various forms.

In FIG. 4, a cylindrical gas combustion space forming body 44a having a plurality of holes 44aa perforated so that the gas generated during combustion (the gas passing through the combustion gas discharge pipe 42 in the drawing) is introduced into the hollow portion inside. It is implemented to include.

In addition, the flame generator 44b is provided to ignite the hydrogen supplied to generate a flame in the inner space of the gas combustion space forming body (44a).

Moreover, the hydrogen supply apparatus 44c which supplies hydrogen to the flame generator 44b is provided.

This structure is characterized by a very good combustion efficiency through the reburn of the exhaust gas.

In the present invention, the water storage tank 80 and the oil storage tank 90 in which water and oil to be supplied to the mixing tank 10 are stored may be provided in the oil / water mixing heater of the present invention.

In this case, it is preferable in view of energy efficiency that water and oil in the water storage tank 80 and the oil storage tank 90 are preheated by the heat generated from the mixture combustion means 40.

In the accompanying drawings, one side of the water storage tank 80 and the oil storage tank 90 is in contact with the combustion furnace 41 of the mixture combustion means 40 to be heated by heat exchange.
