Description

combustible material burner

A year is established for

However, while the garbage is burned in the combustion chamber, a large amount of unburned gas (incomplete combustion gas) is generated due to incomplete combustion, which is exhausted through the flue as it is, thereby aggravating air pollution.

As a related prior art, the soot treatment device of the waste incinerator of Korea Patent Registration No. 10-0218754 has been previously proposed, but the combustion time is delayed due to the lack of oxygen inside the incinerator due to the circulation structure that re-introduces the soot discharged from the chimney to the blower, Due to this oxygen deficiency, incomplete combustion was induced and a large amount of unburned gas was generated.

In addition, in Patent Publication No. 1999-009788, which is another prior art, a technology related to an incinerator configured to simultaneously prevent soot and flashback occurring during incineration has been previously disclosed, but this is because the auxiliary exhaust pipe penetrates the side of the exhaust flue.

1 to 5 are views showing a preferred embodiment of the combustible material combustor provided by the present invention.

In the combustion chamber 100 according to the present invention, a combustible material 10 inlet 120 and a combustion gas exhaust port 140 are formed, and a reprocessing port 160 for treating the ash remaining after burning the combustible material is provided. 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 on the upper outer wall to face each other, and the combustion is generated after combustion on the lower outer wall. A reprocessing port 160 for processing the ash is formed, and the inflammable material 10 inlet 120 and the reprocessing port 160 are operably provided to be opened and closed by a door.

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 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, one side of which 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 the combustion chamber 100 performs the function of an air insulation layer at the bottom, 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 floor 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, the combustion air is distributed through the through-holes to supply combustion air to the plurality of heating passages 250, and the 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 flow path 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).

As such, 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 in the heat insulating chamber 230 and the heating flow path 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, so that combustion efficiency is improved and complete combustion of the combustible material 10 is achieved.

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 ignite 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 on/off controllable.

The injection nozzle 320 is installed in the combustion chamber 100 to ignite the fire to the surface layer of the contained combustible material 10, 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 . ), an air nozzle ( 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 caused 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 inputted 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 the flashback phenomenon during the 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 due to 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 a decrease in thermal power due to interference with the combustible material 10. By supplying sufficient oxygen, complete combustion is achieved, and the combustion air injected through the injection hole 220 disposed in the lower region P2 with the boundary of the combustible material 10 surface layer P is 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, allowing more air to be 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.

The dust collection and retention unit 400 according to the present invention is connected to the exhaust port 140 to first filter harmful particles contained in the exhaust gas by the vortex centrifugal force, and at the same time, the unburned ash that has not been burned in the combustion chamber 100 .

The upper end includes an inducer pipe 440 that extends higher than the dust collecting drum 420, an inducer blower 450 installed at the lower end of the inducer tube 440 to supply air to the discharge pipe 430, and one end of the press-in blower ( 200) and consists of an air pipe 460 for supplying combustion air into the dust collecting drum 420.

At this time, the suction port 422 is formed in 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 downwards, causing a vortex. At this time, the vortex centrifugal force The harmful particles separated by the 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 through the discharge pipe 430 . do.

Even if unburned matter occurs 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 induction 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.

It is provided to collect centrifugally in a state in which the specific gravity is increased by the

That is, the steam (cooling water particles) injected into the dust collecting and retaining unit 400 through the steam pipe 520 is mixed by the exhaust gas and vortex in the dust collecting and retaining unit 400 and harmful particles contained in the exhaust gas ( fine dust) is combined with each other and absorbed by harmful particles to increase specific gravity, and the steam is provided to be dried during the process of mixing with the exhaust gas in the dust collecting and retaining unit 400 .

As such, as the white smoke-type steam generated during the process of water cooling the combustion chamber 100 is mixed with the exhaust gas and dried and decomposed, the smoke generating element including the white smoke is completely removed during the combustion treatment of the inflammable material 10. As the surrounding air and the aesthetic environment are kept clean, the specific gravity of harmful particles contained in the exhaust gas is increased by combining with steam, so there is an advantage in that the collection efficiency by centrifugal separation is improved.
