Description

Rotary Incinerator Assembly {Rotary Incinerator Assembly}

The present invention relates to a rotary incinerator assembly, and more particularly, to a rotary incinerator assembly for incineration while rotating the input waste.

In general, incineration devices are applied in various fields. For example, a waste incinerator is used to burn and treat various household and industrial wastes as well as even waste livestock carcasses.

With the development of various industries in recent years, not only industrial wastes but also various kinds of wastes such as household wastes are generated in large quantities along with the improvement of the standard of living, becoming a major factor of environmental pollution.

Some of these wastes are recyclable, but most are buried in the ground or crushed for incineration. Meanwhile, as an incinerator for incineration of waste, a vertically arranged incinerator was used. Such a vertically arranged aqueduct has the following problems.

First of all, the conventional vertical array incinerator has a problem that the incinerator and dust collector are easily oxidized or corroded by heat, so that the life of the device is shortened, and it is difficult to reduce the size of the device, so that the size of the facility becomes large. During incineration, a large amount of toxic gases such as dioxins are generated, and the technology to effectively reduce them is insufficient.

Meanwhile, in the related art, a horizontal incineration apparatus is also disclosed. The conventional horizontal incineration apparatus is provided in a structure in which the incinerator and the dust collector are in communication with each other through a transfer pipe and a heat recovery pipe.

Specifically, the incinerator includes a conveyor through which waste is transferred and a hopper into which the waste is put. In addition, a blower and a burner are mounted on one side of the incinerator, and the blower and burner are driven through a distribution board. Meanwhile, a collection plate having a certain inclination is mounted inside the incinerator, and the completely incinerated ash is discharged through the suction hole in the center.

In addition, a combustion chamber is formed inside the dust collecting furnace, and a burner is mounted on one side to burn waste in the combustion chamber. A plurality of barrier walls are mounted inside the combustion chamber, and a number of light oil holes are formed in the barrier walls.

In the conventional waste apparatus having such a configuration, the incineration process of the waste and the process of collecting and decomposing toxic gases generated during incineration are simultaneously performed. Therefore, the conventional waste incineration apparatus has a limitation in improving incineration performance as a configuration that depends only on the thermal power of the burner. In addition, when incineration of waste livestock or waste with high moisture content, the burner's thermal power incinerates only the surface (outer) of the waste in the form of lumps, and the incineration heat cannot be transferred to the inside. Problems that are difficult to incinerate are often raised.

In addition, since the conventional waste incineration system relies on the burner's thermal power to incinerate the waste, the fuel cost is relatively high due to the continuous operation of the burner during incineration, and furthermore, the incineration ash (carbonized ash) generated by incomplete combustion during incineration It is difficult to treat, and it is difficult to purify harmful gases (dioxin, soot from incomplete combustion, etc.) contained in the combustion gas.

Meanwhile, the incinerator of the conventional waste incinerator is manufactured in a form in which anchors are installed at regular intervals inside the incinerator casing and concrete is poured. However, in this case, when the incinerator expands due to high temperature heat during the incineration process and then cools, the incinerator shrinks back to its original state. At this time, the problem of cracking in the concrete inside the incinerator was raised.

In addition, due to the anchors installed at regular intervals in the conventional incinerator, the high-temperature heat inside the incinerator is transmitted through the anchor and transferred to the casing of the incinerator during incineration.

In addition, since the conventional incinerator is manufactured by pouring concrete inside the incinerator, a problem has been raised that requires a professional manpower and equipment for pouring, and also difficult to move and install.

In the following description and accompanying drawings, descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. The accompanying drawings are provided as an example in order to sufficiently convey the spirit of the present invention to those skilled in the art. Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms. In addition, the same reference numbers throughout the specification indicate the same elements. It should be noted that the same elements in the drawings are indicated by the same reference numerals wherever possible.

Referring to Figure 1, the rotary incinerator of the present invention is formed in a cylindrical incinerator 50 is configured to rotate by a drive motor. Specifically, the cylindrical incinerator 50 on the base frame 100 installed on the ground as shown in FIG. 3 is configured to rotate in one direction.

Meanwhile, in the incinerator 50, as shown in FIG. 1, a burner B for supplying thermal power into the incinerator 50 is installed at the front end side. In addition, a waste input unit 60 is connected to the end of the incinerator 50. At this time, the waste input unit 60 may crush and supply various wastes.

In addition, inside the incinerator 50, a plurality of transfer blocks 51 are arranged in a spiral shape as shown in FIG. 4. Accordingly, when the incinerator 50 is rotated in one direction, the wastes injected therein are moved to one side (the left side of the incinerator based on FIG. 1) by these transfer blocks 51. That is, the waste supplied through the waste input unit 60 has a conveying direction D1 of the waste conveyed to the burner B side by the conveying block 51 inside the rotating incinerator 50.

In the above-described configuration, the incinerator 50 has a configuration in which the casing 150, the heat insulating panel member 160, and the fireproof panel member 170 are stacked inside the incinerator 50.

Here, the fireproof panel member 170 may be formed of a plurality of ceramic panels. Specifically, as shown in FIG. 5, the first fireproof panel 171 and the second fireproof panel 172 are arranged to be offset from each other in a vertical direction, and thus a stepped portion 173 is formed at the edge thereof. In addition, at least one protruding rib 170h is formed on the outer circumferential surface of the first fireproof panel 171, and a transfer block 51 is formed on the inner surface of the second fireproof panel 172.

The fireproof panel members 170 configured as described above are arranged in a row so that a plurality of the fireproof panel members 170 form the inner circumferential surface of the incinerator 50 so as to form a cylindrical shape.

Meanwhile, an insulating panel member 160 is disposed between the casing 150 and the fireproof panel member 170. In this case, the heat insulating panel member 160 has a structure in which the first heat insulating panel 161 and the second heat insulating panel 162 are arranged to be offset from each other in a vertical direction, and a stepped portion 163 is formed at the edge as shown in FIG. 6. In this case, fixing slits 160h and 160h' may be formed on the inner surface of the first insulating panel and the outer surface of the second insulating panel 162, respectively.

Accordingly, a plurality of heat insulating panel members 160 are arranged in a row so as to be engaged with the stepped portions 163 in a row like the fireproof panel member 170 described above, and are installed in a cylindrically assembled state. At this time, the protruding ribs 150h formed on the inner surface of the casing 150 and the protruding ribs 170h of the fireproof panel member 170 are respectively fitted to the fixing slits 160h and 160h' of the insulating panel member 160, thereby being assembled. It is possible to prevent these panels from flowing with each other so that the incinerator 50 is rotated thereafter.

As described above, in the incinerator 50 of the present invention, a plurality of fire-resistant panel members 170 may be assembled to each other to form a waste transfer structure within the incinerator 50. Therefore, workability is improved compared to the conventional method of pouring concrete, and it is advantageous for moving installation.

In addition, the incinerator 50 of the present invention can be installed by assembling the insulating panel member 160 and the fireproof panel member 170 to the casing 50 without a separate fixture such as an anchor. Therefore, during the incineration process, internal heat is transmitted to the casing 50 through the fixture, thereby solving the problem that the operator suffers burns.

In addition, in the present invention, a plurality of panel members are interlocked to form the inner surface of the incinerator 50, and even if the incinerator 50 is physically expanded and contracted according to the rapid temperature increase and cooling, the interlocked panels can be moved with a certain clearance. Thus, cracks in the incinerator due to thermal expansion can be prevented.

Meanwhile, a plurality of retarding blocks 52a and 52b (FIG. 3) are formed in an area in which the burner B is installed in the incinerator 50. Specifically, the delay blocks 52a and 52b are disposed in a circular band in the incinerator 50, respectively, and the installation intervals are narrower than the transfer blocks 51.

Therefore, the transfer block 51 arranged in a spiral shape serves to transfer the inputted waste in one direction, whereas the retard blocks 52a and 52b transfer the transferred waste to be exposed to the front of the burner (B) for a longer period of time. It plays a role in slowing down the speed. Accordingly, the incineration efficiency can be further improved by exposing the waste transferred to the burner (B) to the flame of the burner (B) for a longer period of time.

At this time, on one side of the incinerator 50 in which the burner (B) is installed, an incineration ash discharging part 56 is formed to discharge completely incinerated ash. In addition, since temperature sensors may be installed on both side walls of the incinerator 50, it is possible to control the operation of the burner B by measuring the internal temperature.

Meanwhile, an exhaust pipe 70 is connected to the front end side of the incinerator 50 (the side wall opposite to the side wall of the burner installation end). An exhaust part 90 is connected to the exhaust pipe 70 to forcibly exhaust the combustion gas inside the incinerator 50. At this time, the combustion gas inside the incinerator 50 has a moving direction D2 of the combustion gas from the burner B side toward the exhaust part 90.

That is, as shown in FIG. 1, the moving direction D1 of the waste and the moving direction D2 of the combustion gas are opposite to each other. Accordingly, the waste supplied through the waste input unit 60 is first dried by an incinerator (high temperature combustion gas) exhausted from the drying area A1 side of the incinerator 50, and then the transfer block 51 ), the wastes are gradually conveyed toward the burner (B), and the wastes start to be burned by the flame of the burner, thereby forming combustion gas (gasification zone; forming A2).

Wastes passing through this gasification zone (A2) are incinerated directly in front of the burner (B) to complete incineration (especially in the retard block; complete combustion in 52a, 52b), and the completely incinerated ash is discharged from the incinerator ( 56) is discharged to the outside of the incinerator 50.

As described above, the rotary incineration apparatus of the present invention constitutes a drying area (A1) and an incineration area (A3) inside the incinerator 50, and a drying process is performed prior to the input waste, and then the incineration process is performed. Even when waste and inorganic waste are mixed, smooth incineration performance can be expected. In other words, high incineration performance can be expected even for waste with high moisture content.

In addition, since the heat of combustion of wastes inside the incinerator 50 can be applied to the drying process or the incineration process, the incineration performance can be significantly improved by utilizing the combustion heat of the waste itself as well as the thermal power of the burner (B).

Meanwhile, on the outside of the incinerator 50, a plurality of external air supply units 65a, 65b, and 65c are disposed at regular intervals. Specifically, in these external air supply units 65a, 65b, 65c, a channel member having a supply channel 68 of a certain space therein is arranged in the form of an annular strip on the outer circumferential surface of the incinerator 50, and communicates from the supply channel 68 As a result, a supply line extending through the wall of the incinerator 50 is formed.

In addition, as shown in FIG. 3, a supply pipe 61 is connected to the supply channel 68 to supply outside air to the supply channel 68, and the supplied outside air can be supplied to the inside of the incinerator 50 through a supply line. . At this time, the supply line is evenly arranged at regular intervals throughout the incinerator 50 to provide sufficient and uniform combustion air required for combustion into the incinerator 50.

Referring back to FIG. 1, the first cooling unit 71 is connected to the exhaust pipe 70. Accordingly, primary cooling of the high-temperature combustion gas exhausted from the incinerator 50 is performed. For example, if the temperature of the exhausted combustion gas is about 1100°C, it is cooled to about 800°C. A part of the primary cooled combustion gas in this way is partially recovered to the waste heat recovery pipe 76 through the waste heat recovery unit 75 and provided to the incinerator 50 again. In this way, the present invention can further improve incineration performance by recovering the waste heat exhausted through the waste heat recovery unit 75.

Meanwhile, the remaining part of the combustion gas passing through the waste heat recovery unit 75 is cooled to about 200°C through the second cooling unit 72. The provision of the multi-stage cooling units 71 and 72 as described above is intended to solve the problem of damage to the filter or deterioration of the durability of the device by the high-temperature combustion gas in the subsequent dust collection process. That is, by lowering the high-temperature combustion gas forcibly exhausted from the incinerator 50 to about 200°C through the multi-stage cooling units 71 and 72, it is possible to prevent the problem of damage to the dust collection filter.

In addition, the combustion gas is discharged to the atmosphere through the exhaust unit 90 in a state in which harmful substances (dioxin, soot, etc.) in the combustion gas are removed through the multi-stage dust collecting units 81 and 82.

In this way, the present invention is incinerated while moving the input waste in one direction by arranging the transfer block 51 in a spiral on the inner circumferential surface of the rotating incinerator 50, and through the exhaust pipe 70, the inside of the incinerator 50 It is configured to forcibly exhaust the combustion gas. Accordingly, since the drying process and the incineration process are performed in one incinerator 50, high incineration performance can be secured even for wastes having a high moisture content.

In addition, since it is possible to utilize the combustion heat of the combustion gas as well as the thermal power of the burner (B) in the incinerator 50, harmful substances such as dioxin and soot generated during the waste incineration process are extinguished by high temperature heat. It can be discharged to prevent environmental pollution.

Meanwhile, when the incineration process of the present invention is described as an example, first, the burner B is operated to preheat the temperature in the incinerator 50 to, for example, 1000°C. After preheating, when the waste is put into the inside of the incinerator 50, the incinerator 50 rotates and the inputted waste is transferred in one direction to incinerate. At this time, the waste is first dried in the drying area (A1), followed by partial combustion in the gasification area (A2), and completely incinerated in the incineration area (A3), and the incineration ash generated at this time is the incineration ash discharge unit (56) It is discharged to the outside through.

Meanwhile, the combustion gas generated in the incineration process has a flow that is forcibly exhausted to the exhaust pipe 70. Accordingly, the high-temperature combustion gas is used in the drying process for the input waste, and helps to increase the overall incineration performance. Therefore, if the high-temperature combustion gas generated in the incineration process is properly controlled, even after the burner B stops operating after the initial preheating, incineration can be performed using its own combustion heat. Accordingly, the operating cost of the incinerator can be significantly reduced.

Meanwhile, the combustion gas discharged through the exhaust pipe 70 is discharged to the atmosphere in a state in which harmful substances (dioxin, soot, etc.) contained in the combustion gas are removed through the dust collectors 81 and 82 after the multi-stage cooling process. Can be reduced.

In the above, the present invention has been illustrated and described with respect to specific embodiments, but the present invention is not limited to the above-described embodiments, and those of ordinary skill in the art to which the present invention pertains, the present invention described in the following claims.
