Description

[Detailed explanation of the invention] "Industrial application field" This invention relates to a waste car tire burner.

``Conventional technology'' In conventional combustion furnaces, the air outlet was opened on the furnace wall, so the air sucked into the interior through the outlet was difficult to reach the center of the rooster, and the waste tires above the center of the rooster were burned whole. It was difficult to do so.

``Problems that the invention attempts to solve'' This invention attempts to obtain a large amount of heat and hot water at a high temperature by completely combusting a waste car tire by letting air reach the center of the rostre.

``Means for solving the problem'' This proposal consists of installing a rostol at the bottom of an upright cylinder whose inner surface is lined with fireproof material, and installing a cylindrical fence for storing waste tires for burning on the top of the rostol. A gap t is interposed between the inner circumferential surface of the cylinder and the outer circumferential surface of the cylindrical fence, a plurality of annular air blowing ducts are provided on the outer circumferential surface of the cylinder, and a large number of jets protrude into the inside of the cylinder from the lower annular air blowing duct. A cylinder is inclined downward toward the inside of the cylinder and intersects diagonally with the diameter direction of the cylinder, and an upper annular air duct is provided in the middle of the cylinder, and a plurality of pipes protrude from the duct into the inside of the cylinder. An ejection cylinder is provided obliquely to the diametrical direction, and a waste tire inlet for burnt tires provided on the side of the cylinder and directly above the lower annular air duct is opened inside the cylindrical fence, and the refractory material is It consists of a waste tire burner in which a water tank surrounding the outer peripheral surface of a stretched upright cylinder is provided above an annular upper air duct.

``Operation'' Therefore, a waste car tire 28 is fed from the conveyor 20 through the waste tire inlet 10 for burning into the center upper surface of the rotor 2 inside the cylindrical fence 3, ignited, and the blower 11 is operated. When air is blown into the interior of the cylinder 1 from the protruding jet tubes 6 and 7, the air jetted out from both the jet tubes 6 and 7 swirls and blows into the cylinder 1.
and the waste tire 28 on the center part of the rotor 2 inside the cylindrical fence 3 and burn it.
The air ejected from the lower ejection tube 6 is sent to the lower center of the rooster 2, burns the carbonized dust falling below the rooster 2, and turns it into white dust.
The swirling air rises in the center along with the combustion gas, and combustion is promoted to the center by the swirling air ejected from the upper jet tube 7 until it is completely combusted and then supplied from the combustion gas duct 12 to the boiler 14 and the like. The refractory material 27 prevents the combustion heat inside the cylinder 1 from dissipating, but a part of the combustion heat passes through the refractory material 27 and heats the water 35 in the water tank 30, and the heated water 35 is sent from the water supply port 31 to the boiler 14. It can be used as a supply for other purposes.

"Example" A rostol 2 is arranged in the lower part of the upright cylinder 1, and a cylindrical fence 3 for storing waste tires for burning is installed on the top surface of the rostol 2.
will be provided. A refractory material 2 is provided on the inner peripheral surface of the cylinder 1.
A gap t is interposed between the inner circumferential surface of the refractory material 27 and the outer circumferential surface of the cylindrical fence 3, and a plurality of annular ventilation ducts 4 and 5 are provided on the outer circumferential surface of the cylinder 1. It is something. The lower annular air duct 4 is provided with a number of ejection tubes 6 that protrude and extend into the inside of the cylinder 1, and the tubes 6 are inclined downwardly toward the inside of the cylinder 1 and parallel to the diameter direction of the cylinder 1. Oblique.
Further, a large number of blowing tubes 7 are provided extending from the upper annular air duct 5 into the inside of the cylinder 1 at an angle to the diametrical direction. A waste tire input port 10 is opened inside a cylindrical fence 3. The cylinder 1 and the cylindrical fence 3 are concentric circles, and the cylindrical fence 3 is made up of a number of upright short rods 8 and connecting horizontal rods 9, and the upper annular air duct 5 is located in the middle of the outer peripheral surface of the cylinder 1. The ejection pipe 7 is preferably horizontal, and the annular air blowing ducts 4 and 5 are connected to the blower 11 by a duct 16. The combustion gas duct 12 is preferably connected to the center of the upper sealed ceiling 13 of the cylinder 1 and connected to the boiler 14, and the direction diagonal to the diametrical direction of the ejection tubes 6, 7 is connected to the center of the upper sealed ceiling 13 of the cylinder 1. They may be in opposite directions.
A water tank 30 is surrounded on the outer circumferential surface of the upright cylinder 1 covered with the refractory material 27 above the upper annular air duct 5. 15 in the figure is a pressure adjustment damper, 17 is an ash discharge port provided at the bottom, 18 is an opening/closing lid thereof, 19 is an opening/closing lid of the material input port 10, and 19 is a material carrying roller conveyor toward the material input port 10. , 21 is a heat insulating material, 22 is an exhaust blower of the boiler 14, 23 and 24 are dust collectors, 25 is a chimney, 26
is a return duct toward the inlet of the blower 11, 29 is an exhaust duct, 30 is a water tank, 31 is a water supply port, 32 is a water supply pipe, 35 is a water level adjustment valve, 34 is a float for adjusting the water level, and 35 is a heated water be.

``Effect'' This project is configured as described above, so the protruding jet tube 6
The air spouted out swirls and reaches the center of the cylindrical fence 3, and fully reaches the waste tire for burning 28 in the center of the rotor 2, and burns it sufficiently and also burns the descending carbonized dust. Not only can this be turned into white dust, but the air jetted out from the upper jet tube 7 also swirls and reaches the center, where it becomes a hard waste round tire 28.
can be easily and completely combusted (at 1200°C or higher), and a large amount of heat at a high temperature can be obtained inexpensively and easily using only the waste round tire 28, and heat dissipation can be prevented by the fireproof material 27 and hot water in the water tank 30. There is a benefit of being able to use hot water.
