Also, by easily replacing only the worn or damaged parts, ease of replacement and economical efficiency are achieved. There is an advantage that can be improved significantly, a detailed description thereof will be described later.

A lower outer cylinder 10 is formed at an outer circumference of the lower inner cylinder 20, and an upper end of the lower outer cylinder 10 is coupled to the outer circumferential surface of the upper outer cylinder shade 32 so that air and dust are not discharged to the outside. In addition, an input door 11 and a recollection door 12 are formed at positions corresponding to the inlet 25 and the re-outlet 26, respectively, to control the opening and closing to inject waste or discharge combusted ash.

In the lower outer cylinder 10 and the lower inner cylinder 20 as described above, the injected waste is primarily combusted to cause decomposition reactions. The injected waste is completely combusted by appropriately controlling the thermal power with fuel, reformed water, and a thermal control blower 110. It creates a spiraling, rapidly rotating air vortex that easily separates dust and dust and releases the natural ash.

The lower outer cylinder 10 and the lower inner cylinder 20 are both connected to the pipe for supplying fuel and reformed water, the upper outer inlet 10 and the lower inner cylinder 20, the upper air inlet tube 91, The upper fuel supply pipe 92 and the reformed water supply pipe 93 are connected to supply air, fuel, and reformed water, respectively, so that the injected waste may gradually burn from the upper portion of the lower inner cylinder 20 to the lower portion.

In the present invention, the upper flange 33 is formed along the lower circumference of the upper outer cylinder 30, and the upper and lower ends based on the upper flange 33 can be separated or assembled with each other, according to the incinerator Since the upper and lower parts of the incinerator can be separated from each other, the upper and lower parts of the pre-manufactured incinerator can be easily moved in the process of manufacturing and installing a large-scale incinerator, as well as the process of prefabricating and manufacturing each part. There is an advantage that can be easily assembled and installed.

Further, by forming the lower flange 13 along the periphery of the lower outer tube 10 and disassembling or assembling the lower outer tube 10 into the upper and lower parts as necessary, It is easier to move the components of the vehicle, as well as to assemble and install them in the required positions.

In addition, by forming a separate lower flange 13 at the stop of the lower outer cylinder 10, it is possible to more easily disassembly and replacement of the lower inner cylinder 20 located therein, in particular the lower outer cylinder ( By separating a portion of the 10) can be easily identified and replaced immediately when the damaged part of the lower part of the inner cylinder 20, it is possible to improve the workability and reduce the replacement cost.

In order to separate and replace the lower inner cylinder 20, the lower inner cylinder 20 of the present invention has a cylindrical shape in which an inlet 25 through which waste is input is formed to provide a space for decomposition of the injected waste. Combustion cylinder 21, the combustion cylinder 21 is spaced apart from the combustion cylinder 21 by a predetermined distance to surround the lower outer periphery of the combustion cylinder 21, connecting to the lower end of the combustion cylinder 21, And a space for disintegrating the injected waste, and the lower end of the combustion cylinder 23 having a plurality of holes formed therein with a plurality of holes formed therein so as to discharge the burned ash and the reformed water to the lower portion. Located at the lower end of the combustion cylinder 23 is fixed to the lower side is preferably made of a cylindrical combustion cylinder holder 24 is formed with a re-outlet 26 for discharging the incinerated ash. .

That is, as shown in Figures 2 and 3, the lower inner cylinder 20 is configured to be separated into a total of four parts or can be combined with each other, and thus the lower inner cylinder which is a space in which the input waste is burned at a high temperature Damage or wear of the (20) has the effect that can be easily separated and replaced only each part.

The upper portion of the combustion cylinder 21 is formed with an inlet 25 so that waste can be introduced into the inside, and one side of the upper air inlet tube 91, the upper fuel supply tube 92, and the reformed water supply tube 93. ) Is connected to each other and receives combustion from the outside with air, fuel and reformed water.

Combustion cylinder holder 22 is coupled to the circumference of the combustion cylinder 21 so as to be spaced apart by a predetermined distance, the combustion cylinder fixture 22 is 1800 ℃ high temperature is discharged to the outside or the heat loss inside the combustion cylinder 21 At the same time acts as a heat shield to prevent this from happening, and serves to fix the combustion cylinder 21 and the outer outer cylinder 10 of the outer side in a fixed position.

The lower part of the combustion cylinder 21 is located under the combustion cylinder 23, which is a space in which the injected waste is combusted, and the combustion cylinder 23 has a structure in which waste and combusted ash and reformed water can be discharged to the lower part at the same time. Consists of

That is, the lower end of the combustion cylinder 23 is coupled to the perforated plate 27 is formed with a plurality of holes, through the perforated plate 27 can be released to the outside by reformed water and finely sized ash, In addition, since the lower air inlet pipe 94 and the lower fuel supply pipe 95 may be connected to receive air and fuel from the lower side, complete combustion may be achieved through additional combustion of waste that is not completely burned.

Therefore, in the related art, a plurality of holes are blocked by waste and ash which are not completely burned, but according to the present invention, the waste and ash collected in the combustion chamber 23 are re-burned to release natural ash and reformed water. This is easier.

Particularly, in the present invention, the shape of the combustion cylinder 23 is manufactured to be inclined downward so as to be narrower than the general cylindrical shape. Thus, the diameter of the lower end is smaller than the diameter of the upper end so as to be inclined. Ash and reforming water can be more easily induced to gather into the perforated plate 27 and re-outlet 26.

A cylindrical combustion cylinder holder 24 is positioned at the lower end of the combustion cylinder 23, and is coupled to the combustion cylinder 23 to fix the combustion cylinder 23 and a lower outlet 26 is formed at the lower side thereof. Can be discharged to the outside.

The refractory brick 70 is coupled to the lower end of the combustion cylinder holder 24 to support the entire structure of the incinerator and discharge the reformed water falling down.

As described above, each of the combustion cylinder 21, the combustion cylinder holder 22, the combustion cylinder 23, and the combustion cylinder holder 24 constituting the lower inner cylinder 20 is formed with a fixed portion, which is coupled to FIGS. As shown in FIG. 3, a first fixing portion 81 protruding inward is formed on an inner surface of the lower combustion cylinder holder 24, and an outer surface of the lower combustion cylinder 23 protrudes outward. A second fixing portion 82 is formed, and a third fixing portion 83 protruding outward is formed on the outer surface of the combustion communication holder 22, and on the outer surface of the combustion communication 21 toward the outside. A protruding fourth fixing portion 84 is formed.

The second fixing part 82 protruding outward from the upper end of the combustion chamber 23 is connected to the bottom of the bottom of the combustion chamber 23, 24 from the upper end of the first fixing part 81 protruding from the inner side of the first fixing part 81 to fix the combustion chamber 23 and the combustible cylinder fixing part 24 to each other.

The third fixing portion 83 protruded from the outer surface of the combustion and fixing frame 22 is engaged with the lower flange 13 formed on the lower outer casing 10 so that the combustion outer casing 22, And the fourth fixing portion 84 protruding from the outer surface of the combustion top 21 is coupled from the top of the combustion top mount 22 so as to be connected to the combustion top 21, So that the fixing table 22 is fixedly coupled.

According to such a coupling structure, the lower inner cylinder 20 can achieve the combustion of the waste and the combustion gas injected as one coupling structure, and a portion of the lower inner cylinder 20 in which the high temperature combustion reaction occurs continuously is Even if damaged or worn, only parts in the corresponding positions can be disassembled and replaced easily, which can shorten the time required for replacement, and also eliminate the need to replace unnecessary parts at once, thereby achieving high economical efficiency.

Hereinafter will be described the operation of the present invention according to the configuration as described above.

First, in order to incinerate tires, medical waste, waste oil, and livestock discharges classified as general waste, waste plastic, rubber, food waste, and industrial waste, which are not suitable for recycling among various kinds of wastes, and incineration can be incinerated. 10) After opening the input door 11 formed in the upper portion of the lower amount of waste through the inlet 25 of the inner cylinder (20).

When the input of the waste is completed by ignition using a manual or automatic ignition device (not shown), and then closing the inlet 25 of the lower inner cylinder 20 and the input door 11 of the lower outer cylinder 10 in sequence.

Thereafter, the operator operates the operation panel (not shown) to drive the blower 110 to supply external air into the incinerator through the upper air inlet pipe 91, and at the same time, a predetermined amount of reforming from the reformed water storage container (not shown). Water is supplied to the lower inner cylinder 20 through the reformed water supply pipe 93.

Due to the reformed water introduced through the reformed water supply pipe 93, the humidity is very high in the lower inner cylinder 20 and in the incinerator, and thus the outer circumference and interview of the lower inner cylinder 20, which is relatively quick external air, is rapidly turned. In the inner circumference, the reformed water droplets form and flows downward.

The reformed water flowing through the inner circumference of the lower inner cylinder 20 as described above and dropped to the center of the lower inner cylinder 20 through the perforated plate 27 is dropped to the refractory brick 70 hung by radiant heat. Some are vaporized again and outflow.

In addition, a part of the reformed water dropped on the refractory brick 70 flows into the inner space of the refractory brick 70 and falls to the bottom plate through the through hole, and the reformed water dropped on the bottom plate is formed in the center of the bottom plate again (not shown). Through the drain pipe (not shown) coupled to the drain pipe through the inflow into the drain (not shown) is collected.

The external air supplied from the blower 110 to the lower inner cylinder 20 through the upper air inlet pipe 91 strongly turns in the tangential counterclockwise direction of the lower outer cylinder 10 to cause vortex, and a part of the upper outer cylinder ( Ascending in the direction of 30), the rest descends while turning to the bottom of the lower outer cylinder 10, and then rises again by the temperature and flows into the upper inner cylinder 40 and the lower inner cylinder 20.

The outside inlet air continuously flowing into the upper inner cylinder 40 and the lower inner cylinder 20 and rapidly turning counterclockwise is mixed with the reformed water sprayed through the reformed water supply pipe 93 in the form of a mist. In the space between the outer cylinder 10 and the upper inner cylinder 40, and the space between the inner inner surface of the upper inner cylinder 40 and the inner inner surface of the lower inner cylinder 20, it is quickly turned counterclockwise.

The inflowing air that turns rapidly is introduced into the lower outer cylinder 10 in a cold state, and the space between the upper outer cylinder 30 and the upper inner cylinder 40, and the space between the lower outer cylinder 10 and the lower inner cylinder 20. Hot while turning quickly in

The hot inlet air turns rapidly upward in the direction of the upper outer cylinder (30), and then enters the upper inner cylinder (40) and the lower inner cylinder (20). The air is in contact with the upper inner cylinder 40 radiated by the cold inlet air introduced through the blower 110 at the outer periphery of the upper inner cylinder 40 to release heat, and the temperature is lowered. The air that has risen from it descends to the bottom.

Air descending and being heated again inside the lower inner cylinder 20 is rapidly turned to the inner surface of the upper inner cylinder 40 and ascended so that the repetitive circulation of air is performed in the incinerator.

Accordingly, the combustion gas generated during the incineration of waste is mixed with the outside air and repeatedly circulated in the incinerator, so that it stays in the incinerator for a long time and is decomposed to high temperature while being frequently in contact with the temperature of 1,800 ° C. in the lower inner cylinder 20. Burned and discharged.

Therefore, the outer periphery of the upper outer cylinder 30 and the lower portion by the flow of air rapidly turning in the space portion between the upper outer cylinder 30 and the upper inner cylinder 40 and the lower outer cylinder 10 and the lower inner cylinder 20. The outer circumference of the outer cylinder 10 may maintain a temperature that is not hot even if the worker touches it.

A portion of the inlet air rapidly turning between the upper outer cylinder 30 and the upper inner cylinder 40 becomes exhaust gas and is discharged to the atmosphere. The outer periphery and exhaust of the exhaust outer cylinder 50 pass through the upper end of the upper inner cylinder 40. It is discharged to the clearance gap between the inner peripheral surfaces of the inner cylinder 60, and is discharged | emitted to the atmosphere through the space between the exhaust outer cylinder 50 and the exhaust inner cylinder 60. As shown in FIG.

In the process where the reformed water is mixed with the outside air is supplied to the lower inner cylinder 20 through the upper air inlet tube 91 and the lower air inlet tube 94, and the waste is incinerated,

Pyrolysis (modification) process,

The chemical reaction occurs in the combustion process, supplying more oxygen to the flames of the garbage, and raising the center temperature to approximately 1,800 ℃, which enables complete combustion of the waste due to high pyrolysis.

등의 유해가스 및 다이옥신이 거의 배출되지 않게 된다.Also, not only soot but also dust (ash)

Hazardous gases such as dioxin and the like are hardly emitted.

That is, by the heat energy generated by the incineration of the garbage, dryness of the garbage (dry distillation, heating and decomposition of the solid organic matter, operation of separating the volatile material and the nonvolatile material) and water vaporization are performed. The combustion gas is completely burned without flowing out to the outside of the incinerator, so that the unburned, odorless, and colorless combustion gas is discharged to the atmosphere through the exhaustion inner cylinder 60 .

In addition, incinerators generate fine ash, fine dust, and dust continuously during the incineration of various types of wastes, and in some incinerators, since the fine dust and dust are discharged into the atmosphere, they cause serious pollution. A separate dust collector or bag filter is used to filter and collect fine dust and dust.

However, the dust collector or bag filter used in the prior art simply installed in the place where the exhaust gas is moved to filter the dust, or the dust is naturally transported by the air pressure in the incinerator, thereby filtering it. The dust collection efficiency was reduced, and some dust and dust, which could not be removed, were discharged. In addition, there was a problem in that the bag filter was expensive to install and replace.

In addition, if a certain amount of fine dust and dust is collected in a process in which the conventional dust collector or bag filter is continuously used, the entire dust collector or bag filter installed after stopping the dust collection process had to be replaced, the process Not only this was complicated, but there was a problem that continuous dust collection could not be achieved.

Accordingly, in the present invention, fine dusts and dusts are easily combined with circulating vortices of air and dust generated by a vacuum pressure applied from the outside of the blower 110, etc., coupled to an incinerator and similar dust generating facility for burning wastes. Collecting, when the dust and dust is collected over a certain amount is provided an air circulation dust collector that can quickly and easily replace the dust collector 105 as needed.

That is, as shown in Figure 4, in the dust collector coupled to the incinerator, it is connected to the lower inner cylinder 20, which provides a space for the first waste decomposition reaction to supply the air for combustion of the waste The lower inner cylinder 20 and the lower outer cylinder is connected to the lower outer cylinder 10 formed to surround the outer periphery of the lower inner cylinder 20 spaced apart by a predetermined distance from the upper air inlet tube 91 and the lower inner cylinder 20. Dust discharge pipe 101 for discharging air and dust from the space between the 10, the blower 110 is connected to the end of the upper air inlet pipe 91 to control the flow and direction of air, the dust discharge pipe 101 Dust collector (100) connected to the end of the dust collector, one end is connected to the blower 110 and the other end is connected to the dust collector 100 to the flow of air generated in the blower 110 to the dust collector ( Connected with 100) It characterized in that it comprises a connecting pipe (102).

As described above, an upper air inlet tube 91 is connected to the lower inner cylinder 20, which provides a space for burning waste, to supply external air containing oxygen, and the upper air inlet tube 91 Blower 110 is connected to the outer end of the) to blow air into the lower inner cylinder (20).

In particular, as shown in Figure 5, the upper air inlet tube 91 is connected to only one side of the lower inner cylinder 20 is introduced to rotate the incoming air counterclockwise, whereby the waste is burned In the process, a flow of air turning counterclockwise is generated.

In addition, the dust discharge pipe 101 is connected to one side of the lower outer cylinder 10, the flow of air generated during the combustion of the waste is the space of the upper outer cylinder 30 and the upper inner cylinder 40 and the While turning down into the space of the lower outer cylinder 10 and the lower inner cylinder 20, various fine dust and dust mixed together in the air may be discharged to the outside through the dust discharge pipe (101).

Therefore, the dust generated during incineration of the waste is turned into the inlet air rapidly turning through the dust discharge pipe 101 formed in the opposite direction of the rotational direction of the external air in the lower outer cylinder 10 is turned into the inlet air The dust is discharged to the dust collector 100 and only clean air is discharged to the atmosphere.

In particular, the present invention includes a connection pipe 102 for connecting the flow of air generated in the blower 110 to the dust collector 100 by connecting between the blower 110 and the dust collector 100, Accordingly, according to the flow of air in the blower 110, it is possible to quickly and surely collect and collect fine dust and dust into the dust collector 100.

That is, in the dust collector used in the related art, it merely serves to collect dust discharged to the outside of the dust collector according to the natural flow of air in the combustion chamber in which combustion occurs, but in the present invention, the blower 110 is applied. The fine dust and dust can be naturally discharged according to the flow of air, and at the same time, the air flow generated by the blower 110 is transferred to the dust collector 100 so that the dust and dust are discharged from the dust collector 100. It is possible to further improve the dust collection performance by sucking with.

In addition, the dust collector 100 is connected to the dust discharge pipe 101, the dust collector 103 of the cylindrical shape providing a space for collecting air and dust primarily, the lower end of the dust collector 103 A dust collecting container 105 coupled to the dust collecting unit 105 for collecting and collecting dust collected in the dust collecting unit 103, and formed at both ends of the dust collecting unit 103, and the dust collecting unit 103 and the dust collecting container 105 It is preferable that it further comprises a coupling portion 104 for coupling, and the dust collector 105 is preferably formed to be detachable from the dust collection unit 103 in accordance with the operation of the coupling portion 104. Do.

That is, the dust discharge pipe 101 and the connection pipe 102 are respectively connected to the dust collection unit 103, according to the operation of the blower 110, the dust discharge pipe 101 inside the relatively low pressure At the same time to form a flow of air in a constant direction to collect the fine dust and dust discharged from the dust discharge pipe 101 to the dust collector 105.

By adding various filters and filtration devices as necessary on the path from which the dust is collected from the dust collecting part 103 to the dust collecting container 105, dust collecting performance and efficiency can be further improved.

In addition, in the present invention, the dust collector 105 is formed to be easily detachable at any time as needed, the dust collector 105 in order to combine or remove the dust collector 105 with the dust collection unit 103 At both ends of the) coupling portion 104 is formed so that the user can easily operate.

However, in the incinerators and dust collectors used in the related art, when the combustion reaction is continuously performed in the incinerator, since the flow of air is continuously generated in the combustion chamber and the dust collector, even if dust and dust are collected in a certain amount or more, Not only the dust collector could not be easily replaced, but there was a problem such that unfiltered dust and harmful substances were easily released into the atmosphere.

Therefore, in the present invention, the dust collector 105 is formed to be easily detachable from the dust collection unit 103, and at the same time the end of the connecting pipe 102 is made to be connected to the dust discharge pipe 101, the dust When the collection unit 103 and the dust collecting container 105 is coupled, the connection of the connection pipe 102 and the dust discharge pipe 101 is made to open and communicate, the dust collecting unit 103 and the dust collecting container 105 When the separation of the connection pipe 102 and the dust discharge pipe 101 is temporarily closed so that the flow of air is blocked.

That is, in the state in which the dust collecting tube 105 is coupled to the dust discharge pipe 101, the connection between the connecting pipe 102 and the dust discharge pipe 101 is opened to the flow and pressure of the air applied from the blower 110. As a result, dust and dust inside the incinerator and the combustion chamber were collected into the dust collecting part 103 and the dust collecting container 105.

On the contrary, in the state in which the dust collecting tube 105 is separated from the dust discharge pipe 101, the flow of air applied from the blower 110 is blocked by blocking the connection between the connection pipe 102 and the dust discharge pipe 101. By preventing the transfer to the dust discharge pipe 101, dust and dust inside the incinerator and combustion chamber are prevented from moving to the dust discharge pipe 101 and the dust collection unit 103.

Accordingly, in the combustion process of the waste, when the dust and dust is filled in the dust collector 105 of a certain capacity, there is an advantage that the dust collector 105 can be replaced at any time, and the operation of the incinerator should be stopped. This can solve the problem of not having to replace the dust collector until the combustion reaction is completed.

In addition, since the dust collector and dust can be collected by setting the space inside the dust collecting chamber 105 at any time, the dust collecting apparatus 105 can exhibit not only improved dust collecting performance but also the air discharged to the outside can be kept more clean. In addition, it has the effect of significantly lowering the emission of various dusts and harmful substances.

The present invention can be applied to a variety of sizes and applications from small to large scale, 15% paper, 10% fiber, 45% synthetic resin, 20% wood, 10% other in the prototype of incineration capacity 300 kg / m ² · kr As a result of the combustion experiment with the composition ratio of waste, the outlet temperature of the exhaust gas was measured to be 911.4 ℃ on average, and in particular, the volatile components and thermally decomposable components were removed and only the non-flammable fraction remained. Loss ignition is 4.87% on average. Considering that the standard loss is about 15% or less, the waste is completely burned and the ability to discharge it to ash is significantly improved. Can be.

In addition, since the waste is the combustion reference to a result of measuring the characteristics of the exhaust gas, the dust content in the exhaust gas in accordance with the invention the reference value of 100mg / Nm ³ and a typical incinerator as about 32.2mg / Nm ³ Remarkably less than the dust content of 385.93mg / Nm ³ , the carbon monoxide (CO) content in the exhaust gas discharged according to the present invention is about 11.4ppm, significantly less than the standard 300ppm and 375.72ppm of the carbon monoxide content of the general incinerator. dioxin in the exhaust gas discharged in accordance with the invention (DXNs) content is approximately 0.038ng-TEQ / the reference value as Nm ³ 5ng-TEQ / Nm ³ and the dioxin content of a typical incinerator 24.09ng-TEQ / Nm seen significantly less than ^3, Can be.

In other words, the inputted waste can be completely burned through high-temperature reforming reaction and high-speed combustion reaction to completely decompose harmful substances, and the exhaust gas also meets all statutory emission standards of 24 harmful substances and simultaneously uses them. Compared to the incinerator, it is possible to emit clean exhaust gas with significantly less pollutants.

Accordingly, the present invention can be used for incineration heat utilization facilities of small, medium and large sizes, as well as various fields such as all combustible waste, general waste, hospital waste, polymer waste, sewage sludge, food waste, industrial sludge, etc. Wastes can be safely incinerated, and the waste can be recycled to various industrial facilities using heating, industrial boilers, and incineration arrangements using the thermal resources generated by incineration. There is an advantage that can be significantly improved.

Furthermore, by forming a structure capable of separating and combining the lower outer cylinder 10 and the lower inner cylinder 20 constituting the combustion chamber in which the high temperature reforming reaction proceeds as described above, partly damaged or worn parts can be quickly formed. As well as replaceable, large-scale incinerator installation can be easily assembled and moved to the location to install after the main part is separated, thereby improving workability and reduce transportation and maintenance costs.
