Abstract
Description
small incinerator
[0001] The present invention relates to a small incinerator.
[0002] Although small incinerators capable of incinerating various types of waste on a small scale have been proposed, they have the problem of causing air pollution because they do not achieve complete combustion.
[0003] In addition, since conventional incinerators are generally structured to force combustion air using a blower, they have the disadvantage of high manufacturing costs.
[0004] Because the forced air is cold, it can lower the combustion temperature and hinder complete combustion. In addition, the forced supply of combustion air has the disadvantage of making it difficult to control the exact amount of air required for combustion.
[0005] Therefore, there is a need for a new incinerator structure that can solve such problems.
[0006] The present invention aims to solve at least one of the above-mentioned problems.
[0007] One embodiment of the present invention aims to provide an incinerator capable of achieving complete combustion.
[0008] One embodiment of the present invention aims to provide an incinerator capable of raising the combustion temperature to 800 to 1000 degrees for complete combustion.
[0009] In addition, one embodiment of the present invention aims to provide an incinerator using a natural intake method rather than a forced intake method using a blower.
[0010] In addition, one embodiment of the present invention aims to provide a small incinerator suitable for household or small-scale industrial use.

[0015] In at least one embodiment of the present invention, an inlet for injecting the incineration object is formed above the exhaust port, and an inlet cover for covering the inlet is additionally included.
[0016] In at least one embodiment of the present invention, the exhaust port is lower in height than the left and right shoulder portions of the return portion.
[0017] In at least one embodiment of the present invention, the combustion chamber is sealed except for the bottom portion and the exhaust port.
[0018] In at least one embodiment of the present invention, the bottom portion further includes a ash tray that slides forward and backward and is drawn in and out, and the outside air flows over a pair of left and right side walls of the ash tray and then flows into the inside of the ash tray and is then introduced into the bottom portion.
[0019] In at least one embodiment of the present invention, the bottom portion includes a first left wall and a first right wall, and the pair of side walls of the ash tray includes a second left wall and a second right wall, wherein the first left wall and the second left wall are spaced apart by a first interval for introducing the outside air, and the first right wall and the second right wall are spaced apart by a second interval for introducing the outside air.

[0052] Hereinafter, an incinerator according to an embodiment of the present invention will be described in detail with reference to the attached drawings.
[0053] Referring to Fig. 1, the incinerator of the present embodiment has an approximately hexahedral shape, but this is only an example and is not necessarily limited thereto.
[0054] The incinerator may include a skeletal frame made up of a number of steel columns and steel plates to form its skeleton.
[0055] The skeletal frame defines the general shape of the exterior of the incinerator, supports a number of plates that constitute the combustion chamber (20) described below, and provides a structure in which the ash tray (10) can be slidably installed.
[0056] As shown in Fig. 1, the incinerator has an inlet (2) formed at the top for injecting the incinerator material (hereinafter, simply referred to as incinerator material), and is provided with an inlet cover (1) for opening and closing the inlet (2).
[0057] A front plate (5) is provided at the front, and the inner surface of the front plate (5) defines the front of the combustion chamber (20).
[0058] The front panel (5) is provided with a viewing port (4) for viewing the inside of the combustion chamber (20) and a viewing port cover (3) for opening and closing the viewing port (4).
[0059] Of course, the surveillance device (4) can also serve as another inlet for injecting small incinerators.
[0060] At the lower center of the incinerator, an ash tray (10), which will be described later, is installed so as to be able to slide in the forward and backward directions.
[0061] The internal structure of the incinerator is described in detail with reference to FIGS. 2 and 3.
[0062] A combustion chamber (20) is provided inside the incinerator as a space where incinerated material is burned. In this embodiment, the combustion chamber (20) is shaped symmetrically left and right, but it does not necessarily have to be symmetrical left and right.
[0063] Referring to Fig. 7, the combustion chamber (20) has a bottom defined at the bottom, an expansion defined above it, and a return defined above the expansion.
[0064] Referring to FIGS. 2 and 3, the bottom portion includes a first left wall (21a), a first right wall (21b), and a floor member (28).
[0065] The floor member (28) supports the incinerated material, has a structure that allows the ash remaining after combustion to pass downward, and allows outside air for combustion air to pass upward.
[0066] For example, the floor member (28) may be a metal perforated plate, a metal mesh, a structure in which a plurality of metal rods are combined in a grid shape, etc., but is not limited thereto.
[0067] The extension is structured such that the left inclined wall (22a) is arranged so as to slope to the left as it goes up from the first left wall (21a), and the right inclined wall (22b) is arranged so as to slope to the right as it goes up from the first right wall (21b).
[0068] The incinerated material placed on the left inclined wall (22a) and the right inclined wall (22b) is pushed down in the inclined direction by its own weight as it is incinerated and can be collected at the bottom.
[0069] Additionally, as the incinerator material is pushed downward, more empty space can be secured within the return section. This empty space secured within the return section can serve as a swirling space for the flame flow described below. During the initial stage of combustion, the air introduced from the bottom is filled, allowing for a rapid supply of air necessary for combustion.
[0070] The return section acts as an air pocket as a storage space for combustion air in the early stages of combustion, and as combustion fully develops, it expands to both sides in the expansion section as described later, and turns the rising flame airflow toward the center and guides it downward again.
[0071] A left vertical wall (24a) and a right vertical wall (24b) are included for the regression section, and a left horizontal wall (26a) and a right horizontal wall (26b) are included to define the upper boundary of the regression section.
[0072] In addition, for the return section, a left first curved plate (23a) that curves between the left inclined wall (22a) and the left vertical wall (24a) of the extension section and a right first curved plate (23b) that curves between the right inclined wall (22b) and the right vertical wall (24b) of the extension section are included.
[0073] In addition, for the return section, a left second curved plate (25a) that curvedly connects between the left vertical wall (24a) and the left horizontal wall (26a), and a right second curved plate (25b) that curvedly connects between the right vertical wall (24b) and the right horizontal wall (26b) are included.
[0074] The inlet (2) is equipped with a left-side input slant plate (2a) and a right-side input slant plate (2b), and includes a left-side third curved plate (27a) that curves between the left-side horizontal wall (26a) of the return section and the left-side input slant plate (2a), and a right-side third curved plate (27b) that curves between the right-side horizontal wall (26b) of the return section and the right-side input slant plate (2b).
[0075] An exhaust port (dh) may be defined between the end of the left third curved plate (27a) and the end of the right third curved plate (27b). Additionally, the exhaust port (dh) may be defined by the end of the left input slant plate (2a) and the end of the right input slant plate (2b).
[0076] Hereinafter, the receptacle (10) and its withdrawal / intake structure will be described with reference to FIGS. 4 and 5.
[0077] First, as shown in Fig. 4, the ash tray (10) includes a front plate (11) equipped with a handle, a bottom plate (13), a second left wall (11a), and a second right wall (11b).
[0078] In addition, the upper part of the second left wall (11a) is provided with a left rail portion (12a) that extends to the left and is then bent downward, and the upper part of the second right wall (11b) is provided with a right rail portion (12b) that extends to the right and is then bent downward.
[0079] The left rail part (12a) is mounted on the left rail (30a) provided in the incinerator frame, and the right rail part (12b) is mounted on the right rail (30b).
[0080] The ash tray (10) moves forward and backward as the left rail portion (12a) slides on the left rail (30a) and the right rail portion (12b) slides on the right rail (30b).
[0081] Referring to FIG. 5, the first left wall (21a) and the second left wall (11a) are spaced apart by a first gap (d1), and the first right wall (21b) and the second right wall (11b) are spaced apart by a second gap (d2).
[0082] The outside air flows over the left rail section (12a), downwards through the first gap (d1), then flows over the lower part of the first left wall (21a) and enters the floor. In addition, the outside air flows over the right rail section (12b), downwards through the second gap (d2), then flows over the lower part of the first right wall (21b) and enters the floor.
[0083] The sum of the first gap (d1) and the second gap (d2) is less than half of the third gap (d3) between the first left wall (21a) and the first right wall (21b) of the bottom.
[0084] As combustion proceeds in the combustion chamber (20), the combustion gas is discharged to the outside through the exhaust port (dh), and since the combustion chamber (20) is a sealed structure except for the exhaust port (dh) and the bottom, outside air is introduced as much as the gas is discharged through the exhaust port (dh).
[0085] Since the incinerator of this embodiment utilizes a natural aspiration system, only the amount of air required for combustion can be introduced. If more air is supplied than required for combustion, the combustion temperature may be lowered by the air, hindering complete combustion.
[0086] When outside air is introduced into the receiver (10), the first gap (d1) and the second gap (d2) are much smaller than the third gap (d3), so the air flow in the first gap (d1) and the second gap (d2) becomes faster, which has the effect of sucking in outside air.
[0087] That is, since the sum of the first interval (d1) and the second interval (d2) is less than half of the third interval (d3), the suction power of the external air is strengthened, so that the supply of combustion air can be smoothly induced in natural intake.
[0088] Figure 6 is a drawing that simulates the initial combustion situation, which will be described below.
[0089] When incinerated material is injected into the combustion chamber (20) and accumulated, initial ignition can be performed using a torch or the like through the injection port (2).
[0090] Since the left input slant plate (2a) is structured to slope downward to the right from the input port (2), and the right input slant plate (2b) is structured to slope downward to the left from the input port (2), the exhaust port (dh) is located lower than the left horizontal wall (26a) defining the left shoulder of the return section and the right horizontal wall (26b) defining the right shoulder.
[0091] Due to this, air pockets (AP) can be formed on both sides of the return section when the incinerator (R) is injected into the combustion chamber (20).
[0092] The air pocket (AP) is filled with air and can quickly supply combustion air at the beginning of combustion.
[0093] That is, as shown in Fig. 6, the flame starts at the upper center of the incinerator (R) by initial ignition, and the air necessary for combustion can be quickly supplied from the air pockets (AP) formed on the left and right sides.
[0094] Meanwhile, Fig. 7 is a drawing for explaining the external air and flame airflow inside the combustion chamber (20), which will be described in detail below.
[0095] As shown in Fig. 7, outside air is introduced through the bottom and expands to the left and right sides of the expansion section. At this time, the flame inside the combustion chamber (20) is swept up in the air flow and expands upward.
[0096] And, the flame stream expanded in the expansion section turns in the return section and returns to the center again.
[0097] At this time, the flame stream is induced to slope downward by the third curved plate on the left (27a) and the third curved plate on the right (27b). This flame stream is radiated toward the incinerator, creating the effect of radiating flames to the incinerator as if using a flamethrower.
[0098] Additionally, the return of such flame streams to the incinerator has the effect of continuously returning heat into the combustion chamber (20), which allows the combustion temperature to rise to a very high temperature.
[0099] Complete combustion can be achieved due to the high temperature rise of the combustion temperature and the flamethrower-like effect.
[0100] Meanwhile, Fig. 8 is a drawing simulating the flame flow that occurs in the case where the second left curved plate (25a) is absent in the return section of the combustion chamber (20). This will be described below.
[0101] As shown in Fig. 8, since the left second curved plate (25a) is absent and the flame airflow is trapped at the corner where the left vertical wall (24a) and the left horizontal wall (26a) meet, there is a problem that the temperature at the corner of the left vertical wall (24a) and the left horizontal wall (26a) rises significantly, causing the corresponding area to melt.
[0102] However, in this embodiment, since there is a second curved plate (25a) on the left, the flame airflow does not stagnate and returns smoothly, so the above problem is prevented.
[0103] The present invention relates to a small incinerator.
