Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a boiler device equipped with a furnace that burns entire waste tires.

``Conventional technology'' Conventionally, there is a method that uses waste tires as fuel in the combustion furnace of a boiler (Utility Model No. 54-37970
issue). However, when burning the entire waste tire, it is difficult to supply air directly to the waste tire on the rostre, and furthermore, it is difficult to blow air to the bottom of the rostrum, so it is difficult to completely burn the waste tire on the rostre. The waste tires on the rostre are in a dry distillation state, and the gas generated from the waste tires is burned above the waste tires, so the temperature inside the furnace is highest far above the rostol. Therefore, the temperature of waste tires is relatively low and it is difficult to melt the wire inside the tire, so it is necessary to provide an outlet for the residual metal wire.
It was difficult to burn the carbonized dust that fell below the rostre into white dust. There is also a waste oil combustion furnace on a grate, which burns the rising gas, and the combustion temperature of the waste oil on the grate is relatively low. Since the boiler is installed outside the firebox, there is a problem in that it is difficult to directly utilize the combustion heat.

``Problems to be solved by the invention'' This invention involves burning the entire waste tire placed on the Roster, raising the combustion temperature of the tire, causing the wires contained therein to melt and drop, and burning the carbonized dust into white dust. The purpose of this project is to obtain waste tire combustion heat and use it directly in the boiler.

"Means for Solving the Problems" In order to achieve the above purpose, the present proposal is as follows: A rostol 2 is provided at the bottom of the upright cylinder 1, a cylindrical fence 3 is provided on the top surface of the rostol 2, and the cylinder 1
A gap t is interposed between the inner peripheral surface of the cylinder 1 and the outer peripheral surface of the cylindrical fence 3, and a plurality of annular fan ducts 4 and 5 are provided on the outer peripheral surface of the cylinder 1, and a gap t is provided between the lower annular fan duct 4 and the outer peripheral surface of the cylindrical fence 3. A large number of injection holes 6 opening into the cylinder 1 are inclined downward toward the inside of the cylinder 1 and obliquely intersect with the diameter direction of the cylinder 1, forming an upper annular air blowing duct 5.
A large number of jet holes 7 open into the inside of the cylinder 1 from
A material input port 10 provided in the cylinder 1 that can be freely opened and closed is opened inside the cylindrical fence 3, and a firebox 29 is provided in which the entire waste tire 28 can be inserted through the input port 10. A waste tire combustion boiler device having a boiler 37 in which a water can 30 is assembled into the cylinder 1 and a plurality of vent pipes 33 opening to the bottom plate 31 and top plate 32 of the water can 30 are provided inside the water can 30. .

Consisting of:

``Operation'' Therefore, the entire waste car tire 28 is introduced from the conveyor 20 through the material input port 10 onto the upper surface of the rostol 2 inside the cylindrical fence 3, and is ignited and the blower 11 is operated to blow the exhaust holes 6, When air is blown into the cylinder 1 from the air outlet 7, the air ejected from both the air outlet holes 6 and 7 swirls around the waste tire 28 on the rotor 2.
burn. The air ejected from the lower jet hole 6 is sent to the lower part of the rostre 2.
The carbonized dust falling below is burned to form white dust 29. In addition, the swirling air ejected from the lower jet hole 6 is resisted by the cylindrical fence 3 and its strong swirling force is inhibited, preventing the tornado phenomenon and causing a stirring phenomenon, which strongly burns the tires 28 on the rostre 2. The combustion temperature of the tire 28 is increased. The swirling air then rises together with the combustion gas, is sufficiently combusted (combustion temperature 1200°C or higher) by the swirling air jetted from the upper jet hole 7, and rises up the ventilation pipe 33.
The temperature of the water 38 on the outer periphery of the water can 30 can be raised to 100°C or higher, and the steam pressure inside the water can 30 can be raised to the required pressure. The diagonal direction of the ejection holes 6, 7 with respect to the diametrical direction may be opposite to each other in both the ejection holes 6, 7.

A large number of injection holes 6 opening into the cylinder 1 are inclined downward toward the inside of the cylinder 1 and obliquely intersect with the diameter direction of the cylinder 1, forming an upper annular air blowing duct 5.
