Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste incinerator capable of utilizing combustion heat generated when incinerating wastes, waste oils and the like for various uses.

[0002]

2. Description of the Related Art Conventionally, a waste incinerator has been known. As shown in FIG. 5, an incinerator for completely burning smoke and dust generated in an incomplete combustion state when incinerating waste is used. The cyclone chamber 21 was juxtaposed to the body 20. In addition, the cooling water is heated to a high temperature using the combustion heat and guided from the lower half of the cooling water jacket of the incinerator to the storage tank installed underground. There is also known a configuration in which the cooling water jacket is guided from the upper part or the middle part of the storage tank. Further, in order to easily burn the waste oil in the waste incinerator, the waste oil is atomized, and a compressor is provided separately from the incinerator in order to form the atomized oil.

[0003]

In the conventional waste incinerator, the waste could not be completely burned by the incinerator body 20 alone, and black smoke and dust were generated due to incomplete combustion. To completely burn this black smoke and dust, the incinerator body 20
The cyclone room 21 was juxtaposed. However, since the cyclone chamber 21 has a size larger than the incinerator body 20, it becomes large as a waste incinerator, and a wide installation space is required. In addition, when transporting, it cannot be transported in the same posture as it is installed, so that it has to be laid down or sometimes disassembled and transported, which is extremely troublesome, and there is a possibility that the waste incinerator may be damaged. Moreover, the cost was considerably high.

[0004] Further, if it is attempted to raise the temperature of the stored hot water by the conventional method, the combustion heat cannot be used efficiently, and the temperature of the stored hot water is lower than the temperature of the cooling water in the cooling water jacket 1. The temperature of the hot water 12 in H was considerably low. Further, when burning waste oil in a waste incinerator, it was necessary to separately prepare a compressor for atomizing the waste oil, thereby causing an increase in cost.

[0005]

It is a fragmentary sectional view showing composition of small incinerator C of the present invention.

In FIG. 1, a waste incinerator A includes an upper incinerator body D and a livestock hot water layer H provided therebelow. The animal heat and hot water layer H does not usually need to be touched, is an obstacle, and is buried in the ground to keep the heat. As shown in FIG. 6, an inlet 22 is provided on the entire surface of the incinerator body D, and the waste is put into the incinerator 3 through the inlet 22 to incinerate the waste to generate heat of combustion, thereby causing incineration. A blower 9 is arranged on the side of the furnace body D.

The hot water jacket 1 is configured to cover the inside of the incinerator 3. A plurality (16 in this embodiment) of air passages 7.7 are provided on the outer periphery of the incinerator 3.
Are provided, and combustion air nozzles 5, 5, ... are opened toward the incinerator 3 in the air passages 7, 7, ... and the air pipe 30 connected to the chimney above the incinerator 3. The air discharged from the blower 9 toward the air passage 7 is guided from the compressed air passage 6 and discharged into the incinerator 3. By discharging air from the combustion air nozzle 5 into the incinerator 3, waste such as tires can be completely burned. As shown in FIG.
The air passage 7 and the cooling water jacket 1 are covered and arranged in a double structure. FIG. 4 shows a circular shape as an example of the incinerator body D. However, the shape is not limited, and another shape, for example, a polygonal shape may be used.

An exhaust chimney 2 is provided vertically in an air pipe 30 in the upper part of the incinerator body D and the upper part of the incinerator 3, and the lower part of the exhaust chimney 2 is disposed so as to enter the incinerator 3. . In other words, the lower part of the exhaust chimney 2 enters below the upper part of the incinerator 3, the lower end of the exhaust chimney 2 is positioned below the upper surface of the incinerator 3, and the lower end of the exhaust chimney 2 and the incinerator 3
The exhaust chimney 2 is formed in a cylindrical shape with a bottom, and the shielding plate 4 has bolts 8 on its lower surface.
Installed by. The shielding plate 4 is located in the incinerator 3
Is smaller than the plane cross-sectional area of the exhaust chimney 2, and the end thereof is provided with an edge 4a (bent downward or upward) to lengthen the discharge path for smoke and incomplete combustion gas. I have. The air passage 7 and the combustion air nozzle 5
Are provided not only on the side surface of the incinerator 3 but also on the ceiling surface of the incinerator 3 and the exhaust chimney 2. In a conventional waste incinerator, as shown in FIG. 3, incompletely combusted black smoke and dust generated in the incinerator 17 directly reach the exhaust chimney 16. In addition, the air passage 18 and the combustion air nozzle 19
Is only halfway along the side of the incinerator body F, and the secondary combustion of incompletely burned black smoke and dust has not been performed.
However, in the present invention, as shown in FIG. 2, black smoke and dust generated in the incinerator 3 in an incompletely combusted state are not directly transferred to the exhaust A communication provided on the lower side surface of the exhaust chimney 2 from the gap between the side wall surface 23 of the incinerator 3 and the shielding plate 4 through a passage 26 formed by the shielding plate 4 and the ceiling surface of the incinerator 3 It is configured to reach the hole 2a.

The incompletely burned black smoke and dust that have passed through the gap between the side wall surface 23 of the incinerator 3 and the shield plate 4 in this manner are provided on the upper side surface and the ceiling surface of the incinerator 3. The secondary combustion is performed by the combustion air discharged from the combustion air nozzle 5 and the combustion air discharged from the combustion air nozzle 5 provided in the exhaust chimney 2 is also completely burned, so that a smokeless state is obtained. . In particular, the passage 26 and the inside of the exhaust chimney 2 are in a state in which combustion is easy to complete because the ratio of combustion air to the volume is larger than that in the incinerator 3. Further, as shown in FIG. 5, a large waste incinerator such as a waste incinerator B in which an incinerator body 20 and a cyclone chamber 21 are juxtaposed as shown in FIG. In the incinerator A, only the incinerator body was sufficient, and the size could be significantly reduced.

When waste such as tires is incinerated, the temperature of the shielding plate 4 in the incinerator 3 becomes particularly high, so that the shielding plate 4 is severely worn. To cope with this, shielding plate 4
Is fixed to the lower part of the waste chimney 2 by bolts 8, and the shielding plate 4
It is configured so that it can be easily replaced if it becomes worn.

In FIG. 1, a cooling water jacket 1 is shown.
The cooling water in the cooling water jacket 1 is pumped up by a pump 13 installed in a pump chamber 14, and the cooling water jacket 1 is drawn from relatively low-temperature livestock water 12 existing in the lower part of the livestock heating water tank H. To be supplied to That is,
A pump chamber 14 is provided between the livestock hot water tank H and the incinerator body D,
In the present embodiment, the pump 13 is disposed in the upper part of one side of the storage hot water tank H, a pump 13 is installed in the pump chamber 14, a water absorption pipe 10a is connected to a water suction port of the pump 13, and a lower end of the water absorption pipe 10a is It is arranged at the lower part of the livestock hot water tank H so as to suck up low temperature water. A cooling water return pipe 10 communicates with a discharge port of the pump 13, and the other end of the cooling water return pipe 10 penetrates the incinerator body D and is inserted into an upper portion of the cooling water jacket 1. A cooling water outlet pipe 11 is provided vertically between the upper part of the cooling water jacket 1 and the upper part of the storage heat and hot water tank H, and the upper end of the cooling water outlet pipe 11 is located in the air in the cooling water jacket 1. The position is lower than the upper end of the pipe 30. An air vent pipe 32 communicates with the upper end of the incinerator body D to bleed air when supplying water or discharge steam when burning.

Accordingly, the relatively low-temperature livestock water 12 is pumped up by the pump 13, and the cooling water is heated to a high temperature in the cooling water jacket 1 by combustion heat generated when the waste is incinerated. The cooling water outlet pipe 11 is connected to the upper part of the cooling water jacket 1, which is the hottest of the high-temperature cooling water.
The cooling water is supplied into the storage tank H through the cooling water outlet pipe 11. As described above, the temperature of the cooling water is raised by the cooling water jacket 1 and the highest temperature of the cooling water is stored in the storage hot water tank H.
With such a configuration, the combustion heat generated when the waste is incinerated can be efficiently used without waste. As a result of continuing the combustion of the waste, the temperature difference between the temperature of the cooling water, which is the highest in the cooling water jacket 1, and the temperature of the storage water 12 in the storage water tank H can be reduced. The hot water 12 which has been heated to a high temperature can be used for various purposes, for example, for heating and snow melting.

Further, a compressed air extraction pipe 15 is provided near the discharge bracket of the blower 9 for extracting compressed air from the compressed air passage 6 below the incinerator body D connected to the discharge side of the blower 9. . Moreover, the insertion tube 3 formed in a cylindrical shape
4 is inserted into the middle part of the side of the incinerator body D so as to penetrate into the incinerator 3. An oil supply pipe 36, which is formed in a cylindrical shape having a tip with a diameter smaller than that of the body and covers the supply pipe 35 on the outer periphery, is inserted into the insertion pipe 34 so that the tip reaches the inside 3 of the incinerator. . The oil supply pipe 36 and the waste oil tank 39
Is connected via an oil supply hose 37, and the air supply pipe 36 and the compressed air outlet pipe 15 are connected via an air supply hose 38. Since the oil supply pipe 36 inserted into the insertion pipe 33 is fixed by the bolt 33, it can be removed or the insertion position into the incinerator 3 can be changed by loosening the bolt 33. The oil supply pipe 36 has an oil amount adjustment valve 4.
Since the number 4 is provided, the supply amount of the waste oil can be adjusted. With such a configuration, the waste oil can be atomized and supplied to the incinerator 3 in an appropriate state, and the waste oil can be incinerated. Conventionally, when incinerating waste oil, a separate compressor was prepared to atomize the waste oil, but if compressed air is taken out from the compressed air extraction pipe 15 provided in the incinerator of the present invention, it is not necessary to separately prepare a compressor. It is gone.

Next, the configuration of the small waste incinerator C will be described with reference to FIG. Small incinerator C is waste incinerator A
The configuration is such that the animal hot water tank H is removed from the tank. Therefore, the cooling water supplied into the cooling water jacket 1 is supplied from outside the waste incinerator. For example, supply pipe 4 supplies tap water to cooling water temporary storage tank 41 attached to the upper side of incinerator body E.
The cooling water supplied through the cooling water supply tank 41 and overflowing from the supply water storage tank 41 is supplied into the cooling water jacket 1 through the cooling water supply pipe 43. The supply pipe 40 is provided with a water level adjusting mechanism 42 for adjusting a supply amount of the cooling water, and is configured so that the cooling water is appropriately supplied without excess or shortage. Further, the cooling water supply pipe 43 is provided as far as possible to the lower portion of the cooling water jacket 1 so that the high-temperature cooling water in the cooling water jacket 1 in the upper layer does not easily flow back into the cooling water temporary storage tank 41. . Also, the cooling water which has become high temperature in the cooling water jacket 1 has only a cooling water outlet pipe 2 provided on the side surface of the incinerator body C only in the upper part having the highest temperature.
5 so that it can overflow and be taken out. The high-temperature cooling water thus taken out is used for various purposes, for example, for heating and snow melting.

[0019]

As described above, the present invention has the following advantages. The cooling water jacket 1 is provided around the inside 3 of the incinerator of the incinerator body D for incinerating waste as claimed in claim 1.
Is arranged, and a livestock hot water tank H is arranged below the incinerator body D,
The cooling water jacket 1 is connected to the storage heat hot water tank H by a pipe, and the cooling water is circulated between the two to store the hot water in the storage heat hot water tank H, so that when waste or waste oil is incinerated, Since the generated combustion heat can be converted to hot water, and a livestock hot water tank that stores the hot water is located at the bottom of the incinerator body D,
The connecting pipe can be shortened, can be moved in a short time, and heat can be efficiently stored during circulation.

Further, since the animal heat tank H is buried underground, the animal heat tank H is not obstructed, the underground part of the incinerator body D can be used effectively, and waste incineration can be performed. The height of the furnace can be kept low. Then, the heat insulating member of the storage heat and hot water tank is omitted, or the heat insulation member is small and the heat radiation amount from the storage heat and hot water tank is reduced, so that the hot water can be efficiently stored.

Further, the cooling water jacket 1 and the storage water tank H are communicated with each other through a cooling water return pipe 10 and a cooling water outlet pipe 11, and a pump 13 is provided in the middle of the cooling water return pipe 10. Since the lower end of the water absorption pipe 10a of the pump 13 is disposed at the lower part of the storage water tank H, the cooling water at a relatively low temperature in the lower part of the storage water tank H can be pumped and returned to the cooling water jacket. In addition, the temperature in the livestock hot water tank H can be quickly increased and maintained at a high temperature.

Further, the cooling water outlet pipe 11 may be arranged as described above.
Is arranged at the upper part in the cooling water jacket 1 and the overflow is caused to flow to the storage hot water tank H.
The high-temperature water that has been warmed in the cooling water jacket 1 is raised, and the hot water is allowed to flow into the storage hot water tank H so that high-temperature water can be stored in the storage hot water tank H. became

Further, the exhaust chimney 2 is vertically arranged on the upper part of the incinerator body D, the lower part of the exhaust chimney 2 enters below the upper part of the incinerator 3 and the lower end of the exhaust chimney 2 Is located below the upper surface of the incinerator 3 and the exhaust chimney 2
Since the shielding plate 4 is disposed substantially horizontally at the lower end, smoke and dust in an incompletely combusted state in the upper part of the incinerator 3 do not directly enter the exhaust chimney 2, and a portion above the shielding plate 4 and The combustion air supplied from the combustion air nozzle 5 again in the exhaust chimney 2 completely burns the combustion chimney, so that the exhaust chimney 2 can be exhausted from the exhaust chimney 2 while maintaining the same incineration power as the conventional one. The cyclone chamber 21 has become unnecessary. As a result, the size of the waste incinerator can be significantly reduced, cost can be reduced, and installation space can be saved.
In addition, the exhaust chimney can be lowered, so that it does not fall down or disassemble during transportation, and the risk of damaging the waste incinerator has been greatly reduced. As a result, the waste incinerator, which used to be only a large product in the past, was able to provide a rich product lineup from small products that can be used in ordinary households to large products. It is now possible to select products according to the requirements.

In addition, since the shield plate 4 is detachable as described in claim 6, even if the shield plate 4 is worn out due to the high temperature when waste such as tires are incinerated, it can be easily replaced with a new shield plate. As a result, the incinerator can be used for a long time without deteriorating its performance. As a result, running costs can be kept low.

Further, an air passage 7 for supplying air to the incinerator 3 is provided on the outer periphery of the incinerator 3, and the cooling water jacket 1 is arranged on the outer periphery of the incinerator body D to form the incinerator body D. The compressed air passage 6 for sending compressed air is formed below the incinerator body D and communicates with the air passage 7, so that compressed air can be uniformly blown into the incinerator 3 from the side. ,
Generation of carbon monoxide and incomplete combustion substances can be reduced, and combustion efficiency can be improved.

Since the compressed air passage 6 is provided with the compressed air discharge pipe 15, the compressed air for atomizing the waste oil when the waste oil is burned is discharged from the compressed air discharge pipe 15. The compressor can be supplied, eliminating the need for a separately prepared compressor, thus reducing costs.
