Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a treatment method and apparatus for generating electric power while treating waste such as old tires, plastics and waste wood.

[0002]

BACKGROUND OF THE INVENTION Discarded old tires are attracting attention as a new environmental problem. Current methods of disposing of old tires include crushing old tires and adding them to a coke oven, using them as fuel, regenerating carbon from old tires, tearing old tires into mats, and turning them into fish reefs. .
In addition, other wastes such as plastics and wood are generally incinerated.

[0003]

However, the amount of old tires consumed by the above treatment method is small in view of the total amount of waste, and most of them are currently dumped in the field. is there. Further, since plastic has a problem such as damage to a furnace due to high temperature, there is a limit to incineration and a limit to recycling treatment.

It is an object of the present invention to provide a method and apparatus for effectively utilizing waste including old tires to solve the problem of waste pollution and at the same time obtaining electric power and heat.

[0005]

The method and apparatus for treating waste according to the present invention is as follows.

1. A step of burning waste in the gas generation tower to generate combustion gas, a step of removing impurities from the combustion gas generated in the step to produce pure gas, and the pure gas produced in the step to an engine A method of treating waste, which comprises the steps of: guiding and using as fuel for this engine to drive a generator to generate electric power.

2. A gas that has a combustion chamber formed in the gas generation tower, an ignition burner is attached to the bottom of the combustion chamber, and multiple air supply holes are provided in the wall around the combustion chamber to supply air from the blower into the combustion chamber. A generator, an impurity removing device which is filled with a catalyst for removing the impurities such as dust by introducing the combustion gas generated in the gas generating device, and a cooling device for the combustion gas discharged from the impurity removing device An apparatus for treating old tires, comprising: a tar removal device that cools with a tar and removes tar from combustion gas; an engine that uses pure gas discharged from the tar removal device as a fuel; and a generator that is driven by the engine.

It is also possible to recover heat from a heat source including a gas generating tower and an engine by a heat medium, and use this heat for hot water supply, heating or cultivation of animals and plants.

[0009]

Function: Old tires, plastics, waste wood, etc. are put into the combustion chamber of the gas generation tower as they are or after being crushed.
After charging a predetermined amount, blower air is blown into the tower to ignite the ignition burner and ignite old tires. When the old tires are fully self-combustible, stop the ignition burner, and then send air to self-combust.
Old tires and the like in the combustion chamber are sufficiently supplied with air from the surroundings and burned to generate combustion gas. This combustion gas is guided to the outside of the tower from a gas inlet attached to the top of the gas generation tower.
Next, it enters into an impurity removing device filled with coke or the like as one catalyst, solid substances such as dust are removed while passing through it, and then enters a cooling device to be cooled. By this cooling, tar and the like in the gas are separated, and the separated tar and the like are removed by the tar removing device. The combustion gas from which tar and the like have been removed is further cleaned, for example, through a filter, and then reaches the engine to be used as this fuel. The engine drives a generator and produces electric power. Exhaust gas discharged from the engine is released into the atmosphere or the soil through the cleaner.

The heat generated from the device is recovered by a heat medium, and this heat is used for heating or hot water supply.

The metal such as the wire remaining at the bottom of the combustion chamber in the gas generation tower is properly taken out of the combustion chamber.

EXAMPLE 1 1 is a gas generator for treating old tires, and this gas generator 1 comprises a gas generating tower 2, a combustion chamber 3 therein, an ignition burner 4, a blower 5, a combustion gas inlet. It consists of six. An air supply hole 7 is provided around the combustion chamber 3, and the air supplied from the blower 5 is supplied into the combustion chamber 3 through the air supply hole 7. Reference numeral 8 is a combustion device for the ignition burner 4, and 9 is an old tire.

Reference numeral 10 denotes an impurity removing device having a plurality of coke 12 filled therein, and the combustion gas recovered from the combustion gas introducing port 6 of the gas generating tower 2 is passed through a conduit 11 into the impurity removing device 10. It is guided to the bottom, passes through the coke 12 while rising, and is recovered from the top.

Reference numeral 13 is a cooling device, and the combustion gas recovered from the impurity removing device 10 passes through the cooling device 13 via the conduit 14 and is cooled to 50 to 60 ° C. to separate tar. . Reference numeral 15 is a tar remover, 16 is a filter, and 17 is an engine, which is driven by the pure gas sent through the filter 16. A generator 18 is driven by the engine 17.

Next, the operation of the above embodiment will be described. In principle, old tires 9 are put into the combustion chamber 3 of the gas generating tower 2 as they are. After charging a predetermined amount,
Combustion air is blown from the blower 5 into the combustion chamber 3, the ignition burner 4 is ignited, and the old tire 9 is ignited. Ignition burner 4 when old tires 9 are ready to self-combust
After that, the air is sent to make it self-combusting. The old tire 9 in the combustion chamber 3 is sufficiently supplied with air from the surroundings and burns to generate combustion gas. This combustion gas is generated in the gas generation tower 2
Is introduced to the outside of the tower through a gas inlet 6 attached to the upper part of the column, and then enters a multi-layered impurity removal device 10 in which coke is used as one catalyst, and solid substances such as dust are removed while passing through this.
