ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a waste tire incinerating system in which waste tires can be continuously burned. More specifically, the present invention relates to a waste tire incinerating and post-treating system in which waste tires can be continuously and efficiently burned, and the discharge gas is utilized as an industrial energy in an efficient manner.
2. Description of the Prior Art
Generally, waste tires cause environmental contaminations, and therefore, waste tires are incinerated by using an incinerating apparatus.
Among the waste tire incinerating apparatuses which have been invented so far, there are Korean Patent Publication No. 1995-1465 and 1995-7416 of the present applicant. Further, an apparatus for utilizing the discharge gas of the burnt tires as an energy is disclosed in Korean Utilit Model No. 1995-2884.
However, in these apparatuses, the disposal of the residual materials is not automatic, or only partly automatic.
Further, the overall structure of the apparatus is complicated, and the installation area becomes large, while the facility cost is high.
Further, waste tires cannot be fed in exact amounts continuously into the incinerating apparatus, and therefore, an exact continuous incineration cannot be realized.
Particularly, waste tires have to be fed in exact amounts, if an efficient incineration is to be realized. However, the sizes of waste tires are various, and therefore, the feeding amount of waste tires into the incinerating apparatus cannot be realized with the result that an efficient incineration cannot be achieved.
Further, in a waste tire incinerating apparatus, the residual materials which remain after the incineration have to be completely removed, if a continuous incineration is to be carried out.
However, in the prior art (Korean Patent Publication No. 1995-7416), the residual materials drop down, and then, the dropped residual materials are collected, with the result that the residual materials are handled in an imperfect manner.
Specifically, within the tires, there are steel wires or steel wire nets for their long durability. These steel wires are not burned, and therefore, they remain after the incineration.
That is, the rubber portions of the waste tires are completely burned, and therefore, the ashes are dropped down after the incineration. However, the steel wires remain mounted on the supporting bars, and therefore, they do not drop down.
Consequently, the residual steel wires have to be pulled sideward to remove them.
However, during the removal of the residual steel wires in this manner, the incinerating operation has to be halted. As a result, a continuous incineration cannot be realized, the incineration cannot be made automatic, and the operation is inefficient.
Further, in addition to the problem of the residual materials, the post treatment of purifying the discharge gas so as to use it as a fuel cannot be carried out in a perfect manner. Therefore, the combustion efficiency of the discharge gas is not high, and the environment is polluted.
SUMMARY OF THE INVENTION
The present invention is intended to overcome the above described disadvantages of the conventional techniques.
Therefore it is an object of the present invention to provide a waste tire incinerating and post-treating system, in which the incinerating system is automatic, the facility cost is lowered, a continuous incineration is realized, and the waste gas purifying efficiency is improved, thereby maximizing the recycling efficiency for the waste gas.
In achieving the above object, the present invention is characterized in that a hoist carrying apparatus is utilized so as to improve the waste tire automatic feeding and the post treatment.
Further, the sizes of the waste tires are sensed when feeding the waste tires into a thermally decomposing furnace, thereby feeding proper amounts of the waste tires into the thermally decomposing furnace, realizing an efficient incineration, and making it possible to continuously handle the residual materials in a continuous automatic manner.
Further, a purifying apparatus purifies the discharge gas to improve the purity of the discharge gas, thereby making it possible to realize a perfect combustion of the discharge gas time.
