Abstract

PROBLEM TO BE SOLVED: To eliminate public trash contamination by waste tires by a method wherein a combustion starts from the uppermost waste tire being housed in a combustion chamber by being stacked, and the combustion is transferred to tires at lower positions in order, and an incomplete combustion gas which is a generation element of smoke at the time of combustion, is burnt in a secondary combustion cylinder, and discharged to the outside. SOLUTION: Waste tires T in a combustion chamber 11 start burning from the uppermost tire T in order. By this combustion, smoke (almost all of it is an incomplete combustion gas) generates, but this smoke gas is joined with air from an air ascending cylinder 2, and is introduced into a secondary combustion cylinder 32 by detouring a detour leading path 43 as shown by arrow 44, and the incomplete combustion gas in the smoke is secondarily burnt by the combustion heat of the tire T, and is discharged to the outside from an air outlet 35 at the upper end through a chimney 36. After the uppermost tire T is burnt, the combustion is transferred to the tire T at the next position, and the tire T starts burning. Thus, the combustion is performed by transferring in order from the uppermost tire T to the tires at lower positions, and by the combustion heat, the surrounding is heated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove that uses a waste tire of an automobile as a fuel.

[0002]

2. Description of the Related Art In recent years of the automobile era, the amount of waste tires such as old tires and tires that cannot be restored due to flat tires is extremely large. Of these waste tires, some are recycled or used as fuel in cement factories, etc., but the demand for these is extremely small compared to the total amount of waste tires, and most waste tires are industrial. Abandoned as waste.

By the way, since a tire of a car generally contains a metal such as a bead ring (wire), incinerating it with a metal causes problems such as damage to the furnace. Therefore, they are usually transported as non-combustible waste to a predetermined waste disposal site for disposal. However, since the amount of these tires used is extremely large, the garbage disposal site becomes full in a short period of time, and it is difficult to secure the disposal site. Also,
When disposing of waste tires, we usually ask a recovery company to do so, but the recovery fee is about 200 yen per tire.

In order to solve the above problems, development of an incinerator for exclusive use of waste tires has been attempted, but the conventional incinerator is constructed mainly for the purpose of efficiently incinerating tires, and the device is large. As the scale becomes larger, the smoke emission prevention device becomes larger, and as a result, there is a problem that the production cost becomes higher. For this reason, the incinerators for waste tires described above have rarely spread, and many waste tires are still disposed of as non-combustible waste (waste), which is one of the causes of waste pollution. It has become.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, in which waste tires are effectively used as fuel, and the amount of smoke generated is suppressed as much as possible to be incinerated. The purpose of the present invention is to provide a heating stove that can contribute to the elimination of dust pollution caused by waste tires by using a simple structure at low cost.

[0006]

In order to achieve the above object, the present invention is a stove that uses waste tires as fuel, and is of a size capable of accommodating a plurality of (tires) waste tires in a laterally stacked manner. Composed of a combustion cylinder having a lower end of the cylindrical body forming the combustion chamber closed with a bottom plate and an upper end opened, and a cylindrical body having a diameter that can be inserted into the circular hole of the waste tire while opening the upper and lower ends, An air rising cylinder fixed on the bottom plate and erected in a central portion of the combustion chamber, an upper lid constituent member attached to an upper end of the combustion cylinder, and the upper lid structure so as to be located above the air rising cylinder. A detour guide attached to the lower part of the member in the horizontal direction, and the bottom plate is provided with an air inlet whose opening degree is adjustable at the lower end of the air rising cylinder, and the upper lid constituent member is , Removably fit on the upper end of the opening of the cylindrical body And a secondary combustion cylinder which is formed of a tubular body having an open lower end, and which protrudes upward in the center of the lid, and an exhaust port provided at the upper end of the secondary combustion cylinder. And the bypass derivation is composed of a plate-shaped body having a larger diameter than the cylindrical body of the air rising cylinder,
With this detouring guide, a gas detouring guide path is formed at the upper end of the combustion chamber so as to bypass the upper end of the opening of the air rising cylinder and the lower end of the opening of the secondary combustion cylinder to communicate with each other. is there.

According to a second aspect of the present invention, in the waste tire stove according to the first aspect, the air rising cylinder is formed of a cylindrical body. The invention according to claim 3 is the waste tire stove according to claim 1 or 2,
An openable / closable residual ash outlet is provided at the lower end of the cylindrical body of the combustion cylinder.

According to a fourth aspect of the present invention, in the waste tire stove according to the first, second or third aspect, the bypass detouring member is formed of a circular plate-shaped body. The invention according to claim 5 is the waste tire stove according to 1, 2, or 3 above, wherein the detour derivative is formed of an inverted conical plate-shaped body. The invention according to claim 6 is the waste tire stove according to claim 1, 2, 3, 4, or 5, characterized in that the secondary combustion cylinder is formed of a cylindrical body.

[0009]

[Operation] While adjusting the opening of the air intake of the combustion cylinder,
Remove the upper lid component from the combustion cylinder, stack a predetermined number of waste tires in a horizontal position and store them in the combustion chamber, and place an igniter such as a rag or newspaper on the top waste tire to ignite (at this time, If necessary, an appropriate amount of kerosene or the like may be added to the ignited object), and then the upper lid constituent member is fitted to the upper end of the opening of the combustion cylinder. As a result, the air from the air intake is introduced to the upper end of the combustion chamber, and the waste tire in the combustion chamber first starts to burn gradually from the uppermost tire. This combustion produces smoke (most of which is incompletely burned gas),
This smoke gas merges with the air from the air rising cylinder, bypasses the bypass detour path, and is introduced into the chamber of the secondary combustion cylinder, in which the incomplete combustion gas in the smoke is secondarily combusted and exhausted at the upper end. It is discharged from the mouth to the outside. Then, after the uppermost waste tire burns, it burns to the next waste tire, and this tire begins to burn.

As described above, according to the present invention, since the uppermost waste tires stacked and accommodated in the combustion chamber start to burn and then sequentially shift to the lower tires, the amount of smoke generated during combustion is essentially small. At the same time, since the incomplete combustion gas, which is the element for generating the smoke, is burned in the secondary combustion cylinder and discharged to the outside, the amount of smoke in the exhaust gas decreases.
