[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire incinerator, and more particularly to a tire incinerator which burns a waste tire to obtain hot water and can use the hot water in various places.

[0002]

2. Description of the Related Art Conventionally, as a tire incinerator of this type, for example, as shown in FIG. 9, a primary combustion chamber 1 having a tubular shape in which a tire T is burned, and an upper portion of the primary combustion chamber 1 are provided. A plurality of air supplies that are provided so as to communicate with the secondary combustion chamber 2 that is continuously provided to the primary combustion chamber 1 from the external air duct 3 along the inner circumference of the wall surface of the primary combustion chamber 1 and that supplies combustion air to the primary combustion chamber 1. A mouth 4, an air supply member 5 provided in the secondary combustion chamber 2 for supplying combustion air to the secondary combustion chamber 2, and a tire T provided on a side portion of the primary combustion chamber 1 and capable of opening and closing. Mouth 6
A rostrut 7 provided in an intermediate portion of the primary combustion chamber 1 for supporting the loaded tire T in an upright state; and a water passage 8 provided in contact with the outer wall of the primary combustion chamber 1 for flowing water.
It has and.

Then, the tire T, which has been injected from the injection port 6 in the primary combustion chamber 1, is supported by the rostrut 7 for combustion, and further combustion is ensured in the secondary combustion chamber 2 so that the tire T flows into the water passage 8. The water to be heated is heated and the hot water is used in various places (for example, Japanese Patent Laid-Open No. 56-13).
3501 publication).

[0004]

By the way, in this conventional tire incinerator, the water passage 8 has the primary combustion chamber 1.
Since it is provided in contact with the outer wall of the primary combustion chamber 1, the outer wall of the primary combustion chamber 1 is cooled by water, so that the temperature in the primary combustion chamber 1 cannot be raised to a high temperature, resulting in insufficient combustion and black smoke. There is a problem in that the combustion efficiency may be poor because the heat may be generated or the fire may be extinguished in some cases.

Further, as the combustion of the tire T progresses, the tire T
Becomes a carbide and falls from the rostrur 7, and this accumulates at the bottom of the primary combustion chamber 1 and it becomes impossible to perform combustion of this carbide. Therefore, there is a problem that the combustion efficiency is poor.

Further, the combustion air supplied to the primary combustion chamber 1 is supplied from a large number of air supply ports 4 dispersed on the inner circumference of the outer wall, and the jetting of this air accelerates the combustion of the site. There was a problem that the outer wall centering on this portion was damaged quickly and was inferior in durability.

The present invention has been made in view of the above problems, and an object thereof is to prevent the temperature in the primary combustion chamber from being lowered by water so that the high temperature can be maintained and still remain in the latter stage of combustion. This is to improve the combustion efficiency of the tire by completely burning the carbide.

[0008] And, if necessary, in the air supply as well, the influence on the outer wall of the primary combustion chamber is reduced to improve the durability, and the structure of the air supply is simplified as much as possible so that the tire on the tire is installed. To improve the combustion efficiency by supplying sufficient air, and to keep the water warmed until the tire burns up and the next tire is loaded. Another issue was how to improve temperature efficiency.

[0009]

SUMMARY OF THE INVENTION A tire incinerator of the present invention for solving the above problems is a primary combustion chamber in which a tire is burned, which is formed of a metal plate in a tubular shape, and a primary combustion chamber of the primary combustion chamber. A chimney that is continuously provided in the upper portion and has a space that communicates with the primary combustion chamber forms a secondary combustion chamber, an air supply unit that supplies combustion air to the primary and secondary combustion chambers, and an upper portion of the primary combustion chamber. And the opening and closing of the tire that can be opened and closed, the grate laid on the lower combustion chamber of the primary combustion chamber where the tire is placed with its axis vertical and the air is timed from below the grate. An air port capable of being blown out, a metal pipe having a coiled portion around the outer periphery of the primary combustion chamber that is wound in a coil shape in a state of being separated from the outer wall of the combustion chamber, through which water flows, and the coiled shape. Wall that covers the part and outer wall of the primary combustion chamber An air chamber is formed for accommodating the coil-shaped portion, in which a pump supplying water to the pipe.

[0010] If necessary, the air supply unit is provided with a cylinder standing upright along the inside of the primary combustion chamber, and air is supplied to the lower end of the cylinder from outside the primary combustion chamber. A vent is provided, and a blower that supplies air to the air supply port is connected,
A plurality of side outlets for blowing air into the primary combustion chamber are provided on the wall of the cylinder.

Further, it is effective that the cylinder of the air supply unit is provided below the chimney, and the upper outlet for blowing air to the secondary combustion chamber of the chimney is provided above the cylinder.

It is effective to connect the blower to the air port and provide an opening / closing valve that can be opened / closed at appropriate times in the air passage extending from the blower to the air port and blows air from the air port when the air passage is opened.

If necessary, a burner capable of heating the inside of the primary combustion chamber is provided in the grate.

Further, it is effective to form a preheating pipe portion by arranging a preceding pipe reaching the coiled portion of the pipe in the primary combustion chamber.

[0015]

According to the tire incinerator having such a structure, the tire is put into the primary combustion chamber through the charging port, placed on the gravel of the grate, and ignited on the tire.
When the air supply from the air port is stopped and the air is supplied from the air supply unit to the primary and secondary combustion chambers, the tire burns. Combustion gas in the primary combustion chamber rises to the secondary combustion chamber and is almost completely combusted in the secondary combustion chamber. This combustion heats the wall of the primary combustion chamber to a high temperature. During combustion, water is supplied to the pipe by the pump.
The coiled portion of the pipe is housed in the air chamber and is wound around the outer periphery of the primary combustion chamber in a state of being separated from the outer wall of the primary combustion chamber. The air in the chamber is heated, and the heat transfer from the air heats the coiled portion, thereby heating the water. In this case, since the coil-shaped portion is separated from the outer wall of the primary combustion chamber, the outer wall of the primary combustion chamber is not cooled by water, and therefore the temperature in the primary combustion chamber cannot be high enough. It prevents the situation where the combustion is insufficient and black smoke is generated or the fire is extinguished.

Further, as the tire combustion progresses, the tire becomes a carbide, but since gravel is laid in the rustle part, when air is blown out from the air port, the gravel is heated red. So, with this gravel,
The carbide of the tire is burned, and the burning is ensured accordingly. By adjusting the blowing of air from the air port in this way, the combustion of the tire is made to proceed as slowly as possible, and the heat retention of the pipe is maintained for a long time.

Further, an upper air outlet 25 that blows air to the secondary combustion chamber 12 of the chimney 11 is provided on the upper portion of the cylindrical body 21.

Reference numeral 30 denotes a grate portion provided in the lower portion of the primary combustion chamber 10. The grate portion 31 and the crushed stone laid on the grate portion 31 on which the tire T is placed with its axis vertical. It is composed of gravel 32. An air port 36 is provided below the primary combustion chamber 10 and blows air into the primary combustion chamber 10 from the lower side of the roster portion 30. The air blower 23 for supplying air is connected to the air port 36. ing. An on-off valve 33 manually opens and closes the air passage 34 to the air port 36. Reference numeral 35 is a storage tank that stores the air from the blower 23 in order to evenly blow out the air from the air port 36. Reference numeral 37 is an air volume adjustment damper of the blower 23.

Reference numeral 40 is a pipe through which water is circulated. The pipe 40 has a coil-shaped portion 41 wound around the outer periphery of the primary combustion chamber 10 in a coil shape in a state of being separated from the outer wall 10a of the combustion chamber 10 (interval L in FIG. 3). In FIG. 2, reference numeral 46 denotes a fixing metal member that fixes the coiled portion 41 to the outer wall 10a in a separated state. The front pipe reaching the coil-shaped portion 41 of the pipe 40 is piped in the primary combustion chamber 10, and more specifically, enters from the lower side of the primary combustion chamber 10 into the inside thereof and rises along the above-mentioned cylindrical body 21 while being secondary. A preheating pipe portion 42 is preliminarily preheated, which is piped so as to reach the combustion chamber 12 and return to the outside from the secondary combustion chamber 12 here. The preheating pipe portion 42 reaches a storage tank 43 that temporarily stores water. The storage tank 43 is connected to the coil-shaped portion 41, and the pipe 40 in the middle of this connection is connected.
A circulation pump 44 for circulating water is installed.

As shown in FIG. 1, the outlet side 40a of the coiled portion 41 connects the primary combustion chamber 10 with the support plate 1 for the chimney 11.
3 is drawn through so as to support 3, and protrudes to the outside.
Therefore, the support strength of the support plate 13 is improved, and the chimney 11 is reliably supported. Further, the pipe 40 is connected to a heating pipe 45 for heating a vinyl house described later. Reference numeral 47 in FIG. 2 denotes a protective plate that covers and protects the preheating pipe portion 42 in the secondary combustion chamber 12. An air chamber 50 is formed by a cover wall 51 that covers the pipe 40 of the coil-shaped portion 41 and an outer wall 10a of the primary combustion chamber 10 and accommodates the coil-shaped portion 41.

Further, a heavy oil burner 60 capable of heating the inside of the primary combustion chamber 10 is provided in the roast portion 30. As shown in FIG. 6, 61 is a tank for supplying heavy oil to the heavy oil burner 60, 62 is a normally-closed on-off valve interposed between the tank 61 and the burner 60, and only for the time set by the timer 63. The heavy oil in the tank 61 is supplied to the burner 60 by being opened. Reference numeral 64 is an air tube for blowing air into the burner 60.

Next, a description will be given of the entire system of the greenhouse in which the tire incinerator S is used. As shown in FIG. 7, a heating pipe 45 through which water flows is embedded or laid in the greenhouse 70, and the outlet of the heating pipe 45 is connected to the inlet of the pipe 40. The inlet of 45 is connected to the outlet of the pipe 40, and water is circulated through the heating pipe 45 of the vinyl greenhouse 70 and the incinerator S by the circulation pump 44.

Therefore, in this system, when the tire incinerator S according to the embodiment is operated, the inlet 1
The lid 15 of No. 4 is opened, one waste tire T is put in the primary combustion chamber 10, and it mounts on the gravel 32 of the grate part 30. next,
The on-off valve 33 of the air passage 34 to the air port 36 is opened, kerosene is applied to the tire T, and the tire T is ignited. In this case, since air flows in from the air port 36, combustion of the tire T is promoted. When the tire T has been burned to some extent, the opening / closing valve 33 of the air passage 34 to the air port 36 is closed, and the air of the blower 23 is sent to the tubular body 21 of the air supply unit 20. As a result, air is blown out from the side outlet 24 of the tubular body 21. In this case, as shown in FIG. 3, the air is blown out radially from the cylindrical body 21, so that convection easily occurs, and therefore combustion of the tire T is promoted. As a result, for several minutes until the furnace is warmed at the beginning of ignition, pale smoke is generated due to low temperature combustion of the vaporized gas, but thereafter, high heat is maintained and combustion is performed in a completely smokeless state.

Further, since the combustion air supplied to the primary combustion chamber 10 is blown out from the cylindrical body 21, even if the combustion of the jetting portion of air is promoted, it has an effect on the cylindrical body 21,
The influence on the primary combustion chamber 10 is almost eliminated, and therefore the damage to the wall of the primary combustion chamber 10 is suppressed.
The durability is improved. If the tubular body 21 is damaged, only the tubular body 21 needs to be replaced, and the maintenance becomes easier.

Further, the combustion gas in the primary combustion chamber 10 rises to the secondary combustion chamber 12, and in the secondary combustion chamber 12, the cylindrical body 2
Since air is blown out from the upper outlet 25 of 1,
The combustion air causes almost complete combustion. And
A substantially smokeless gas is emitted from the chimney 11. In this case, since the air is supplied to the secondary combustion chamber 12 from the cylindrical body 21, it is not necessary to separately provide an air supply structure as in the conventional case, and the structure of air supply is simplified accordingly. Therefore, the cost can be reduced.

By this combustion, the wall portion of the primary combustion chamber 10 is heated to a high temperature. Then, during combustion, water is circulated through the pipe 40 by the circulation pump 44, and the coil-shaped portion 41 of the pipe 40 is housed in the air chamber 50, and the outer wall 10a of the combustion chamber is provided on the outer periphery of the primary combustion chamber 10. Since it is wound in a state of being separated from, the radiant heat of the wall portion of the primary combustion chamber 10 or the air in the air chamber 50 is heated, and the coil-shaped portion 41 is heated by the heat transfer from this air. As a result, the circulating water is heated. In this case, since the coil-shaped portion 41 is separated from the outer wall 10a of the primary combustion chamber 10, the outer wall 10a of the primary combustion chamber 10 is not cooled by water, and therefore the primary combustion chamber 1
It is possible to prevent the situation where the temperature within 0 cannot reach the high temperature, the combustion becomes insufficient and the black smoke is generated, or the fire is extinguished, and the waste tire T is surely burned and the water is heated. Will be able to.

Further, since the preheating pipe part 42 in front of the coil-shaped part 41 of the pipe 40 is piped in the primary combustion chamber 10, it will be heated in advance.
Since water heated to some extent flows through the coil-shaped portion 41,
The temperature rise is accelerated accordingly.

When the combustion of the tire T progresses, the tire T
Becomes a carbide. When the tire T becomes a carbide and accumulates on the roast portion 30, the opening / closing valve 33 of the air passage 34 is opened. As a result, air is blown out from the air port 36, so that the gravel 32 of the roster portion 30 is red-heated, and therefore, the carbide of the tire T is burned by the gravel 32, so that the combustion is surely performed. Done. Then, by adjusting the blowing of the air from the air port 36 in this way, the combustion of the tire T is caused to proceed as slowly as possible, and the heat retention of the pipe 40 is maintained for a long time. That is, when the charcoal remaining after the carbonization combustion is combusted by supplying oxygen from under the rostr part 30, the gravel 32 becomes red-heated and becomes super-high heat, and a long amount of black charcoal containing carbon is completely smokeless until it becomes white ash. It becomes possible to burn for a time (for example, about 5 hours). Further, the gravel 32 protects the primary combustion chamber 10 and also functions as a heat storage material for maintaining a high temperature.

Then, in the course of burning the carbide of the tire T, the next new waste tire T is put into the primary combustion chamber 10 by opening the lid 15 of the charging port 14 in the same manner as described above, and the gravel 32 of the grate 32 is put. It is placed on top and the on-off valve 33 of the air passage 34 is closed as above. Thereby, similarly to the above, the tire T is burned and the water is heated. By thus adjusting the blowing of air from the air port 36, the combustion of the tire T is advanced as slowly as possible, and the heat retention of the pipe 40 is maintained for a long time. If the opening / closing valve 33 of the air passage 34 to the air port 36 is opened during the combustion period of the tire T, the combustion time of the tire T can be shortened.

Further, the timer 63 is appropriately set,
For example, if the time is set at night when the tire T cannot be put in, the opening / closing valve 62 opens at the time set by the timer 63, and the tank 6 is inserted into the heavy oil burner 60.
Since the heavy oil is supplied from 1, the heavy oil is ignited and the heavy oil burns. Therefore, even if the tire T is not put in and the combustion of the components of the tire T is finished, the heavy oil continues to burn, so that the heating of the water is continued until the tire T burns and the next tire T is put in. The state is maintained.

[0033]

[Experimental Example] Next, an experimental example will be described. In this example,
80m in diameter in 1m ³ size divided by cover wall 51
m × height 90 cm × thickness 9 mm cylindrical primary combustion chamber 10
And a chimney 11 having a diameter of 24 cm and a height of 1.8 m was provided to form a cylindrical secondary combustion chamber 12. Further, as the tubular body 21 of the air supply unit 20, a pipe having a diameter of 16 cm divided into halves was used. Further, in the cylindrical body 21, the outlets in the central row were formed using washers having holes with a diameter of 10 mm, and four outlets were formed at intervals of 9 mm. Further, in the other rows, nine pieces having a diameter of 7.5 mm were formed. As the hot water pipe 40, an iron pipe 40 with a diameter of 5 cm for shiitake was used, and its coil-shaped portion 41 was placed 9 mm away from the primary combustion furnace.

In the incinerator S for the tire T, one round-class "round tire" was put in every 40 minutes, and a combustion test was conducted. In this test, 5 tires T were put in, and the charcoal on the rostr part 30 after combustion was combusted for 6 hours, and finally all combustibles became white ash in the warm water state of 50 ° C. and the combustion was completed. . As a result, 15
℃ water = 720 liters in 1 hour at 50 ℃ (up to 95 ℃
It was found to have the ability to increase (25,216 kcal).

The results of the operation for cultivation of crops are as follows. The daytime solar heat is utilized to heat the nutrients by photosynthesis, and the tires T are heated from about 3:00 to 6:00 in the evening, and for the next 6 hours, unattended charcoal burns until about 12 pm until midnight. It was possible to keep warm with the tire T of 5 tires per hour, and after that, although there was a drop in air temperature at dawn, it became possible to secure a minimum room temperature of 10 ° C. Since the circulating water can be heated for a long time due to the high heat of the crushed stone rustle portion 30 that glows red, it is possible to save labor because no human power is required for about 5 hours at midnight except when the tire T is introduced during the daytime.

That is, the tire T that remains as burnt residue at night
In order to burn the carbide in small quantities for a long time, by opening the on-off valve 33 in the air passage 34 and adjusting the damper 37 to reduce the amount of air blown to the combustion chamber, while maintaining the superhigh heat of the carbide with the red-heated gravel loss It can be completely smokelessly burned until it becomes white ash in about 5 to 6 hours. Furthermore, by switching to automatic operation of the heavy oil burner 60,
The required temperature can be secured.

In the above system, since the heat radiation from the outer wall of the smoke exhaust, which is the secondary combustion chamber 12, is extremely large, if a hot air collector is installed and a perforated vinyl duct is used to blow air over a long distance, circulation will occur. It can be used as heating heat of clean and dry warm air to prevent diseases caused by high temperature and high humidity of crop cultivation house with warm water.

FIG. 8 shows a modification of the incinerator. In this system, a pipe 40a in front of the pipe that reaches the preheating pipe portion 42 is embedded in the gravel 32 of the grate 32, and heat generated by heating the gravel 32 is taken out as preheating.

In the above embodiment, the structure of the air supply unit 20 is not limited to that described above, and may be changed appropriately. Further, the system in which the above embodiment is used is not limited to the vinyl house described above, and it goes without saying that any system may be used.

[0040]

As described above, according to the tire incinerator of the present invention, since the coiled portion of the pipe is housed in the air chamber and is wound around the outer periphery of the primary combustion chamber, it is wound.
The coil-shaped part can be heated by the radiant heat of the wall of the primary combustion chamber or the heat transfer from the air of the air chamber.Therefore, the outer wall of the primary combustion chamber is not cooled by water. It is possible to prevent black smoke from being generated due to insufficient combustion due to insufficient temperature, or to extinguish the fire in some cases. can do.

Further, if air is blown out from the air port provided on the lower side of the rustle portion in a timely manner, the gravel will be red-heated. Therefore, the gravel will surely burn the remaining carbide in the latter stage of combustion of the tire. Therefore, there is an effect that combustion efficiency can be significantly improved. Further, since the air can be blown out from the air port in a timely manner, the combustion of the tire can be advanced as slowly as possible, and the heat retention of the pipe can be maintained for a long time.

Further, in the case where the air supply unit is provided with a cylindrical body provided with a plurality of side outlets along the inside of the primary combustion chamber, and air is blown out from the side outlets by a blower, , Even if the combustion of the air jet portion is promoted, it has an effect on the cylinder, but has almost no effect on the wall portion of the primary combustion chamber, and therefore suppresses damage to the outer wall of the primary combustion chamber, The durability can be improved. Also,
If the cylinder is damaged, replace only the cylinder,
Therefore, maintenance becomes easier.

Further, when the cylinder of the air supply unit is provided below the chimney and the upper outlet for blowing air to the secondary combustion chamber of the chimney is provided above the cylinder, the air to the secondary combustion chamber is It is not necessary to separately provide an air supply structure as in the conventional case, and it is possible to perform the supply with a single cylindrical body. Therefore, the air supply structure can be simplified and the cost can be reduced. Can be achieved.

When the blower is connected to the air port, and an air passage from the blower to the air port is provided with an opening / closing valve that can be opened / closed at any time and blows air from the air port when the tire is opened, The air can be supplied at the start of combustion or when the remaining tire carbide is burned, so combustion can be promoted, combustion efficiency can be improved, and the blower can be used to supply air to the cylinder. Since they can be shared, the structure can be simplified and the cost can be reduced accordingly.

Further, in the case where a burner capable of heating the primary combustion chamber is provided in the rustle portion, if the burner is ignited when the tire is no longer loaded, the tire burns and the next tire is loaded. Until that time, the heating state of water can be maintained, and there is an effect that it is possible to prevent a temperature drop in the pipe.

Furthermore, when a preheating pipe part in which a preceding pipe reaching the coiled part of the pipe is piped in the primary combustion chamber is provided, water which has been heated to some extent can be flown to the coiled part. The heating efficiency can be improved.
