The present invention relates to a combustible material combustor, which is a smoke containing white lead during combustion treatment of combustible material by improving the structure to dry and decompose by mixing white smoke type steam generated during the process of water-cooling the combustion chamber with exhaust gas. The combustion chamber 100 so that the generating element is completely removed to keep the surrounding air and the aesthetic environment clean, and the specific gravity of the harmful particles contained in the exhaust gas is increased by combining with steam, so that the collection efficiency by centrifugal separation can be improved. The press-in blowing unit 200, the combustion burner unit 300, the dust collection and retention unit 400, and the chamber 500 are the main components. And in the present invention, the combustible material 10 refers to a material that burns easily when ignited, including various kinds of garbage, wood, and coal.

The combustion chamber 100 according to the present invention is provided with a combustible material 10 inlet 120 and a combustion gas exhaust port 140 formed, and a reprocessing port 160 for processing the ash remaining after burning the combustible material is provided at the lower portion. Referring to FIG. 2 , the combustion chamber 100 has the upper and lower portions closed, and the combustible material 10 inlet 120 and the combustion gas exhaust port 140 are disposed to face each other on the upper outer wall, and the combustion is generated on the lower outer wall after combustion. A reprocessing port 160 for processing the ash is formed, and the inflammable material 10 inlet 120 and the reprocessing port 160 are provided so as to be able to be opened and closed by a door.

The press-in blower 200 according to the present invention is configured to inject combustion air through a plurality of injection holes 220 formed in the longitudinal direction on the inner wall of the combustion chamber 100 .

The press-in blower 200 includes an insulating chamber 230 formed as an isolated space under the combustion chamber 100, a press-in blower 240 connected to the thermal insulation chamber 230 to supply combustion air, and a combustion chamber ( 100) It is installed on the outer wall and communicates with the plurality of injection holes 220 and one side is connected to the insulation chamber 230 and consists of a plurality of heating passages 250 for distributing and supplying combustion air to the injection holes 220 .

Here, the insulation chamber 230 is formed as an isolation compartment independent from the combustion chamber 100 by a fire-resistant insulation material formed on the bottom of the combustion chamber 100 as shown in FIG. 4, or is formed on the lower outer peripheral surface of the combustion chamber 100 as shown in FIG. Since it performs the function of an air insulation layer at the bottom of the combustion chamber 100, the combustion air (external air) supplied through the press-in blower 240 is preheated as well as blocking the loss of heating heat through the bottom and the lower outer peripheral surface of the combustion chamber 100.

The heat insulation chamber 230 has a plurality of through holes 232 formed in a radial shape, and the combustion air is distributed through the through holes to supply combustion air to the plurality of heating passages 250, and the heat insulation chamber 230 is It is connected to a heating passage 250 to be described later to supply combustion air into the combustion chamber.

And the heating passage 250 is formed in a simple configuration in which a vertical bar having a 'L'-shaped cross-sectional structure or a 'C'-shaped cross-sectional structure as shown in FIG. 9 is mounted in the combustion chamber 100 as shown in the enlarged view of FIG. 220 is disposed on a straight line in the longitudinal or transverse direction to correspond to the heating flow path (250).

In this way, the combustion air (external air) supplied from the press-in blower 240 is preheated by the combustion heat generated in the combustion chamber 100 while moving through the insulation chamber 230 and the heating passage 250 in the combustion chamber ( 100) As it is provided to be supplied to the inside, the combustion air temperature is constantly heated and supplied without being affected by external temperature changes, thereby improving combustion efficiency and facilitating complete combustion of the combustible material 10 .

On the other hand, the injection hole 220 may be formed so as to gradually expand the diameter toward the lower direction of the combustion chamber (100). In this case, even if some of the injection ports 220 are blocked by the combustion product 10, more air is supplied to the combustion product due to the wider injection hole 220 under the surface layer P, which leads to complete combustion of the combustion product 10. With the effect, as the combustible material 10 burns down, the height of the surface layer P of the combustible material 10 is lowered, which is exposed to the top of the surface layer P and is fully open. Due to the expanded diameter of 220, the combustion air injection amount to the surface layer P of the combustible material 10 is uniformly maintained.

In the combustion burner unit 300 according to the present invention, an injection nozzle 320 for supplying fuel (gas or kerosene) to light a fire in the combustion chamber 100 is installed, and the fuel injection operation is performed by the control unit 340 . It is provided to be adjusted on/off.

The injection nozzle 320 is installed in the combustion chamber 100 to ignite a fire to the surface layer of the combustible material 10 accommodated, or is installed in the secondary combustion chamber 100B of another embodiment of FIG. 6 to be described below and installed in the secondary combustion chamber (100B) is configured to maintain the internal temperature of 800℃ or more.

For example, when the fuel is kerosene or kerosene, as shown in FIG. 3 , the combustion burner unit 300 is connected to a fuel tank 350 in which fuel is stored, and the fuel tank 350 to inject fuel into the injection nozzle 320 . ), one end is connected to the fuel pump 360 supplying to the side, and the heat insulation chamber 230, and the other end is installed in a form to surround the injection nozzle 320, and an air nozzle for injecting combustion air into the combustion chamber 100 ( 370), and when the fuel is gas, the combustion burner unit 300 may include an injection nozzle 320 for supplying gas, an air nozzle 370, and a spark plug (not shown).

Due to the structure in which the injection nozzle 320 is not exposed into the combustion chamber 100 and the outside of the injection nozzle is surrounded by the air nozzle 370 , the combustion air in which the injection nozzle 320 is injected through the air nozzle 370 . As it is protected by cooling by the combustion chamber 100, thermal deformation of the injection nozzle 320 due to internal combustion heat and clogging by foreign substances are prevented.

In addition, the air nozzle 370 is located adjacent to the inlet 120 and opposite to the exhaust port 140 , but the air injection direction is configured to face the exhaust port 140 so that even if the inlet is opened during combustion, the flame flows backward to the inlet. It should be directed in the direction of the exhaust port to increase the safety of use.

Additionally, in order to prevent a flashback phenomenon in which a flame is ejected into the inlet 120 when a combustible material is injected into the inlet 120 , the bottom edge of the combustion chamber 100 located at the inlet 120 is connected to the insulation chamber 230 . and a swash plate 260 having a plurality of injection holes 220 is formed. Since the swash plate 260 is formed so that the combustion air supplied to the injection port 220 is injected toward the exhaust port 140 side, it is possible to suppress a flashback phenomenon during combustion operation.

In the combustible material combustor of the present invention, combustion air is supplied into the combustion chamber 100 in a 360° direction through the press-in blower 200 in a state in which the combustible material 10 is previously stacked in the combustion chamber 100, while the combustion burner unit It has a downward combustion structure that is ignited from the surface layer of the combustible material 10 by the fuel injected from 300 and burns down.

That is, in the downward combustion structure in which the combustible material 10 is ignited from the surface layer and burns down, the combustible material 10 is completely burned in a high temperature environment of 600° C. or higher as the combustion air is sufficiently supplied into the combustion chamber in the 360° direction. Air pollution caused by unburned gas is prevented.

4, the combustion air injected from the injection port 220 located at a height corresponding to the surface layer P of the combustible material 10 stirs the combustion ash, so that the combustible material 10 surface layer P is the combustion ash In addition, the injection port 220 located in the upper region P1 with the boundary between the inflammable material 10 and the surface layer P of the combustible material 10 prevents the deterioration of the thermal power due to interference with the combustible material 10. In order to achieve complete combustion due to sufficient oxygen by supplying the combustible material 10, the combustion air injected through the injection port 220 disposed in the lower region P2 bordering the surface layer P of the combustible material 10 is a combustible material (10) Penetrates between the combustible materials 10 to form an air passage 12 between the combustible materials 10, while helping to dry the moisture contained in the combustible material 10, so that more air is supplied to the combustible material in the downward combustion process.

In this way, even if the combustible material 10 is not stirred by applying a separate agitator as the combustible material as well as the combustion ash are stirred by the combustion air injected from the side wall of the combustion chamber 100 through the injection port 220, the combustible material (10) As the combustion air is sufficiently supplied into the combustion chamber from the 360° direction while it goes down from the surface layer, a stable and smooth combustion action is provided.

At this time, the suction port 422 is formed at an eccentric position of the dust collecting drum 420, and the exhaust gas moving into the dust collecting drum 420 rides on the inner peripheral surface of the dust collecting drum 420 and moves downward while generating a vortex. At this time, the vortex centrifugal force The harmful particles separated by the movement are moved downward and are collected on the floor of the dust collecting drum 420 , and the exhaust gas is sucked into the multi-pipe 432 by the blowing pressure that moves upward through the induction pipe 440 and is exhausted by riding the discharge pipe 430 . do.

Even if unburned matter is generated in the combustion chamber 100 by the above structure, the unburned matter is re-burned by oxygen supplied from the press-in blower 200 while passing through the dust collection and retention unit 400 to significantly reduce the generation of pollutants. can

Meanwhile, the manned blower 450 is set to an increased output compared to the blowing capacity of the press-in blower 240 . Accordingly, as the amount of exhaust gas exhausted through the exhaust pipe 430 compared to the amount of combustion air injected into the combustion chamber 100 increases, the exhaust gas flows smoothly from the combustion chamber 100 to the dust collector 400 side, and the combustion process is performed. Even if the inflammable material 10 inlet 120 is opened during the process, a safety accident due to the flame backflow phenomenon is prevented.
