Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is capable of almost completely burning combustible waste such as waste tires, waste rubbers and waste oil into fuel through a diffusion decompression type preheated air mixing combustion tube.
It is possible to remove the pollutant incompletely burned substances generated in the combustion process and to use the high-temperature heat energy generated by re-combusting the incompletely burned gas in a flame state like an industrial oil burner according to the purpose. The present invention relates to a burner device that uses toxic waste as fuel.

[0002]

2. Description of the Related Art Generally, burners use oils such as light oil and bunker C oil, and there is a waste treatment device that burns and incinerates waste tires, waste rubbers, waste oil, etc. There was no burner device such as an oil burner that produces flame and generates high-temperature heat energy.

The reason for this is that flammable wastes do not burn as easily as oils, but incomplete combustion gases such as soot generated during combustion even when oils are sprinkled and burned become sources of air pollution. , Has a negative impact on environmental hygiene.

Further, in order to burn the incompletely combusted gas in the second heating, the incompletely combusted gas has a high flash point.
This is because a large amount of energy-consuming high-temperature special combustion system that must maintain a high-temperature environment of 00 ° C to 1,300 ° C is required.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to minimize the amount of heating energy required in the secondary heating combustion process of incompletely combustible gas of combustible waste, and to reduce diffusion decompression type preheated air. By burning the combustible waste not only by reburning through a mixed combustion tube without requiring additional energy, but also by burning the combustible waste as a thermal energy industrial burner The main purpose is to be able to use it directly.

[0006]

In order to achieve the above-mentioned object, the present invention forms an air chamber between inner and outer walls, perforates a large number of pores in the inner wall, and has a preheating burner in the upper part and a passage in front of it. The tip end crater of the diffusion decompression type preheated air-mixing combustion tube, which is supplied with air from an external fan via, is opened to the outside.

[0007]

The present invention will be described in detail with reference to the accompanying drawings.

A lower part of a main body (1) having a combustion chamber (10) having an air passage (13) formed on an entire peripheral surface between an outer wall (12) and an inner wall (11) to which air is supplied by a fan (3). On the side, a fuel inlet (15) and a rostrut (16) on which a combustible waste is placed are fixedly installed at predetermined positions below the combustion chamber, and a large number of them are arranged at regular intervals on the entire inner wall surface above the rostrul. A preheating burner (2) which is inserted into the inside of the main body (1) and is installed inside is attached to the upper side of the fan (14) by a passage (41) by a passage (41). Of a diffusion decompression type preheated air mixing combustion tube (40) equipped with an air chamber (4) (Air Chamber) for preheated air mixing supply and diffusion tube into which the air delivered from 3) flows in through an air passageway (13). Open crater (42) opened to the outside of body (1) It is a structure.

The air chamber (4) for supplying the preheated air and cooling the diffusion tube has a tapered inlet (43) with a wide inner and outer sides, and the outer peripheral wall has a passage () through which air from the air passage (13) flows. 41) A long member having a constant width and made of a heat-resistant and acid-resistant metal plate in a tapered air chamber (44) which becomes narrower as the air chamber (4) for preheated air mixture supply and diffusion pipe cooling connected with 41) becomes outward. The combustion pipe (40) is provided with a diffusion decompression type preheated air mixing combustion pipe (40) having a certain distance (45t) from the peripheral edge of the inlet inner plate toward the crater (42) side with (45). ) On the crater side of the preheated air discharge pipe (4
6) is located on the central axis of the combustion tube (40), and
An air inflow pipe (47) from the air chamber (44) was fixedly installed above and below it. Further, a flame guiding guide portion (48) is fixedly provided on the inner peripheral edge of the crater (42).

An unexplained reference numeral 5 is a combustible waste, and 6 is a combustion sludge extraction pipe for the combustible waste.

The operation and effect of the device of the present invention configured as described above will be described by way of examples.

First, the fuel inlet (15) is opened, and the combustible waste (5) is placed on the rustle (16).

Next, the preheating burner (2) is ignited, and the combustible waste is ignited by utilizing an oil or waste initial ignition device. At the same time as this, the fan (3) is operated to deliver compressed air.

The compressed air is supplied to the inner and outer walls (11, 1) of the main body (1).
Air is introduced into the first combustion chamber (10) in the body (1) through the pores (14) formed in the inner wall (11) while passing through the inside of the peripheral wall of the body (1) through the air passage (13) between the two. If the air is supplied and the input port (15) is closed while the air is appropriately preheated by the combustion heat of the combustible waste and the thermal power of the operating preheating burner (2), there is no problem in the air supply.

On the other hand, in the combustion progress of the combustible waste (5), the gases having a low flash point, that is, a gas having a large ionization tendency burns first, and the polymer gases having a high flash point are aggregated while rising. Although it is carbonized and converted into incompletely combusted gas as the temperature decreases, a preheating burner (2) is used as a means to prevent this, and heating at a high temperature of 1,000 ° C. or higher produces Facilitates combustion.
On the other hand, the high temperature air supplied through the air chamber (4) is diffused in the combustion tube (40) at a rate of about, that is,
By supplying only the air supply amount necessary for complete combustion, a flame that is completely combusted at a high temperature is generated.

Therefore, even if the inlet (15) is closed, there is no problem in supplying air for combustion, that is, appropriately preheated oxygen supply.

Then, the incomplete combustion gas, which is roughly divided into soot and smoke generated during the combustion of the combustible waste (5), is tapered by the thermal power of the preheating burner (2) into the tapered inlet (43) of the combustion pipe (40). ) It is reheated to a temperature of about 1,000 ° C in the forward direction, and this preheated air that has been heated to high temperature passes through the pipe (47) and the discharge pipe (46) and flows into the combustion pipe (40) through the discharge pores (46h) and is mixed. And long material (45) in the air chamber (44)
It also directly flows in from the gap (45t).

At this time, the preheating burner (2) is connected to the combustion chamber (1
Incomplete combustion gas that was not burned in 0) facilitates to enter the inlet (43) of the diffusion decompression type preheated air-mixing combustion tube (40) and prevent the flashback phenomenon together with the guide role. And also performs a heating function to appropriately raise the temperature of the incomplete combustion gas that enters.

The reason why the combustion pipe (40) is of the diffusion decompression type is that preheated air required for recombustion while the incomplete combustion gas passes through the combustion pipe (40) is diffusion-decompressed. That is,
This is because it has a function of optimizing the combustion conditions of the oxide by supplying the preheated air accurately and in a balanced manner regardless of the recombustion expansion of the incompletely burned gas, and The air supply system is provided with a gap (45t) along the length direction of the combustion pipe (40) so that the flame is supplied in the same manner as the combustion proceeding direction without interruption of the air supply according to the diffusion ratio. By doing so, the combustion efficiency is further enhanced.

In the present invention, the preheating burner mounting position and the cooling means are air-cooled or water-cooled type, the position of the charging port and the preheating burner and the combustion tubes are installed in parallel in two or more vertically or horizontally. A simple design change is included in the technical gist of the present invention.
