Description

The mixing burner system of oil and air

Looking at the use of the present invention when looking at the conventional technology described above as a burner system (hereinafter, burner system) to mix and burn the oil and air that can efficiently use bunker oil, diesel, etc. used in the boiler, incinerator, boiler, automobile Many technologies have been developed and used to reduce the energy of bunker oil, diesel, oil, etc. and increase thermal efficiency.

Among these techniques, a technique similar to the configuration of the present invention includes a method of improving water efficiency by mixing water with oil, a burner which re-inhales combustion gas in a combustion chamber and mixes it with energy to burn it, and first combustion in an automotive engine chamber of the combustion chamber. And the technology of re-suctioning and burning the exhaust gas discharged has been put into practical use.

Looking at the problems of the existing technology, the burner using a mixture of water and oil pumps bunker oil and water with a high-pressure pump and forcibly decomposed and mixed by a rotary blade configured inside the housing and then sprayed from the nozzle of the burner to save energy and It is said to improve thermal efficiency.

If the above arguments are based on natural theory, the thermal efficiency should be reduced by the dilution of water in oil. However, according to the above claim, when water is diluted in an appropriate amount and sprayed through a nozzle, water is diluted even more finely than oil that is not diluted when oil only passes, thereby overcoming the efficiency of energy consumed by diluting water. Will also remain. As a result, about 20% of energy is saved according to this efficiency.

Based on natural theory, water dies and water vapor also plays a role in reducing the efficiency of thermal energy. Therefore, the oil and gas of the present invention can be decomposed in the sense that it can be more effective as it can prevent the energy loss caused by water if it can improve the spraying effect when passing through the burner nozzle without diluting the water. Invented the art of mixing.

In another conventional technology, a burner that recovers combustion gas from a boiler combustion chamber into a burner and mixes it with oil, and a technique of increasing energy efficiency by spraying the nozzle by a method of re-suctioning exhaust gas from an automobile engine combustion chamber is commercialized.

In describing the problem of the above technique, as a boiler burner, the high-temperature combustion gas is diluted with oil to heat the oil and the heated oil is changed into gas. In addition, the combustion gas is also a gas is injected from the nozzle when mixed with oil, and the heat efficiency is increased when it is burned, it is considered that energy saving is natural.

However, the combustion gas of the combustion chamber does not have oxygen as a source of combustion. Therefore, the combustion gas sucked into the burner is forced to inject the combustion gas from the nozzle. Therefore, the part where combustion gas is injected is obstructed to pure oxygen inflow and disappears in the state that it is not 100% burned, and it has become the main culprit of inefficient energy waste and polluting the atmospheric environment. In addition, in the car engine vaporizer, the energy is burned momentarily, and the unburned energy is discharged to the exhaust port, which is a serious social problem that pollutes the atmosphere.

In order to solve such a problem, a technology for re-suctioning the first combustion combustion gas is developed and used. Nevertheless, it is not completely burned, which pollutes the atmosphere and wastes valuable energy.

The present invention for solving such a problem solves all the above problems by securing the disadvantages caused by the microscopic decomposition and mixing of the liquid and gas in the above-described existing technology.

The present invention solves the problem of the above-mentioned Korean Patent No. 0148443, "mixing device of liquid and gas" to save energy in industrial or incinerator, boiler, automobile operation and to prevent air pollution by complete combustion The purpose is to provide a burner system that mixes oil and air to combust.

The present invention provides a practical and economical burner by developing a burner system that mixes and burns oil and air, which is more effective compared to the existing technology, and the construction and operation effects thereof will be described below with reference to the accompanying drawings. Same as

In the above-described configuration, the fluid pumped by the pump p moving along the driving means 1 naturally accelerates the flow velocity due to the diameter narrowed at the distal end of the discharge conduit 2d in the air intake device 2. Outside air is introduced into the housing 3 through the discharge line 2e together with the fluid.

An air valve 2g was formed in the air intake device 2 having the above-described configuration. The configuration of the air valve is configured to be able to appropriately adjust the inflow amount of air in accordance with the soil output ejected from the discharge pipe (2d). Therefore, the configuration of the air valve was configured to easily adjust the intake amount of air.

Through the above configuration, the rotary blades 5a were configured to rotate the liquid and gas sucked into the housing 3 according to the rotary mixing means 5.

Referring to the configuration of the rotary blade 5a, which is the configuration of the rotary mixing means 5 shown in FIG. 2, the rotary blade 5c. 5c 'is formed on the rotary blade and the grinding blade 5b protrudes on both sides of the rotary blade. ) And the grinding blade cross-section (5a '. 5a "), and each of the grinding blades constituted a plurality of rotary grinding spheres.

Referring to the configuration of the fixed partition 6 'of the fixed mixing means 6 integrated with the housing 3 shown in FIG. 3, a plurality of fixed grinding holes 6a were formed in the partition formed integrally with the housing. The shape of the fixed pulverizer can be configured in various ways, but the nozzle type in which the sucked liquid and gas are sprayed has been found to be the most efficient.

The practical configuration of the rotary blade and the fixed partition having the above-described configuration constitutes the rotary blade 5a protruding from the crushed blade end portion 5a '. 5a "and the rotary blade end surface portion 5a' and the fixed partition wall. The gap between the end faces 6b of 6 'was closely formed, so that the configuration of the rotary blade 5a constituted between the fixed partition wall and the fixed partition wall is the cross section of the rotary blade double-sided grinding blade 5a'. 5a '. 5a ") was formed between the end faces 6c. 6b of the fixed partition.

Looking at the effect of the above-mentioned rotary mixing means, the mixing and mixing by the rotation of the rotary grinding wheel configured in the rotary blade (5a), the mixed and mixed fluid by the rotary blade of the above configuration is configured in the fixed partition 6 ' It mixes again by the fixed grinding | pulverization opening 6a. When the fluid passes through the fixed grinding hole, the rotational inertia is stopped and sprayed, and the front and rear surfaces of the fixed grinding hole 6a and the end faces 6b and 6c are cut and disassembled by the end surface of the rotary blade. The bubbles are finely decomposed and mixed into a volume of 10-30micron.

The pump used in the above-described configuration was configured to have an outlet having a diameter in which the discharge was pressurized to a pressure of 3-4 kg / cm 2 in the housing to maintain the pressure using a pump capable of pumping at a pressure of 3-4 kg / cm 2. The housing 3 itself becomes a pressurized tank because a 3-4 kg / cm2 load effect occurs by the discharge port size of the above-described configuration. Therefore, a separate pressurization device becomes unnecessary, and thus, finely decomposed bubble particles in oil are decomposed and mixed into finer particles by water pressure. In this process, the bubble volume of the mixed gas was measured to be 3-5 microns.

Looking at the configuration and effect of the pressurizing device 9 is composed of a sealed pressurization chamber (9a) having a suction port and a discharge port and an inner wall (9c) as a pressure wall (9b) inside, the pressurizing device (9) inside In the heating device 9c or the boiler combustion chamber combustion gas or the heat of the automobile engine exhaust pipe is configured to be heated adjacent to the outside of the pressurizing device. Since it is impossible to escape into the furnace, the air bubbles already finely decomposed by the pressure of 3-4 kg / cm 2, such as the discharge pressure of the pump, are compressed by hydraulic pressure. As a result, the air bubbles are decomposed finely once again in the process of being compressed by hydraulic pressure, and thus the compressed air is expanded while being discharged out of the tank 9a. In this process, it is broken down into finer particles.

Referring to the configuration of the mixing device B of FIG. 4, in the configuration of FIG. 1, instead of the air intake device 2, a proper amount of compressed air compressed by a separate compressor is forced into the housing 3 together with oil. After disposing and mixing by rotation mixing means and fixed mixing means having the same configuration as that of FIG. 1, the pressure mixing device 9 and the heating device 9c decompose and mix more finely.

When the amount of oil used is small, it is impossible to introduce air by the flow rate using the air suction device 2 configured in FIG. 4 is an invention that is very easy to manufacture and use a burner for use in a car or a small boiler that cannot use the air suction device.

The configuration of the mixing device C shown in FIG. 5 is different from the configuration shown in FIG. 1 and is a vacuum pump mixing device by suction force of the vacuum pump p '. Likewise, a large number of vacuum blades were constructed, and each blade had an angle in the opposite direction to the rotation direction as compared to the front portion p1 ', and each blade had a wider width. ) Packed both the front part of the front vacuum part (p3) and the outer diameter of the vacuum wing, and packed the front part only in a separate configuration, not the outer diameter, and the back vacuum part (p4) which is the rear part of the vacuum wing. And a vacuum discharge port p4 'is formed outside the rear part. Also, as shown in Fig. 2, the diameter of the inner suction port 7a is larger than the diameter of the suction port 7 "and the air pipe 2f of the air suction device 2a is formed. The air pipe was configured with an air valve (2h). Therefore, in the case of assembling the vacuum vane, the vacuum vane was configured to be adjacent to the upper end of the housing, the lower end of the wider space was configured to the eccentric so as to constitute a vacuum, the check valve (p2) was configured in the discharge port formed in the upper end.

When explaining the effect of the above configuration, the air or liquid is strongly sucked by the circular wing configuration composed of the angle and rotational direction of the front and rear parts of the vacuum blade, and the front and rear vacuum parts are packaged. Due to the effect of blocking the air, the loss of the vacuum force is prevented and discharged to the vacuum discharge port p4 'without wasting energy.

As a method for increasing the vacuum force, a device for blocking the space between the front vacuum part p3 and the housing was solved to solve the problem that the discharged air or liquid was re-introduced into the suction port.

If the air valve of the above configuration is properly opened, air and liquid are sucked at the same time, and the liquid and gas are decomposed and mixed as in the mixing apparatus A B.

The inventors of the present invention studied the results of various methods, including the configuration of the rotor blades and the fixed bulkheads in five or more stages and the rotational speed from 500 rotations per minute to 3600 or more in a number of experiments. Even if only one fixed bulkhead and the pulverized wing are composed, when the fixed bulkhead and the rotary wing are closely configured, the efficiency is superior to that of the multi-stage effect, and the bubbles are decomposed into 10-30 micron volume.

As such, the decomposed and mixed oil and gas are once again decomposed and mixed into 1-20 microns by hydraulic pressure in the pressure chamber, so that sufficient oxygen is dissolved in the oil. The oil itself is also sufficiently decomposed so that complete combustion occurs during combustion.

Oil and gas that are decomposed and mixed in the burner of the present invention are heated and ignited in a nozzle to be burned efficiently, maximizing energy efficiency and thermal efficiency by 30% compared to the existing technology, as well as completely burning noxious gas in the combustion gas with complete combustion. We believe that this will help to solve the air environment problem.
