BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cremation incinerator for supplying ashes by completely incinerating fluid at high temperatures, and more particularly, through the storage of exhaust gas, reburning in the exhaust system, and the use of exhaust gas burners. The present invention relates to energy-saving and eco-friendly cremation incinerator which minimizes the emission of pollutants such as nitrogen oxides by recombustion while improving energy saving and thermal efficiency through increase and air heating.

The cremator is a furnace facility for supplying ashes by completely incinerating a fluid, that is, a deceased body at a high temperature, and the use of a cremation incinerator is rapidly increasing as the funeral procedure is increased through cremation.

By the way, such a cremation incinerator has a bogie method, that is, an oriental style and a cabinet cabinet method, that is, a western style or a rostol type according to the installation method.

For example, the former balance method is to move the inside of the crematory while the tube is placed on the trolley to perform a make-up, and to take out the trolley out of the carcass for the remedy of the remains after the cremation, so that the supply and demand of the remains is possible. to be.

And, in the case of the cabinet or rostol method, the tube is pushed into the crematorium as it is, without additional support, and the makeup is completed and the ashes are put in the ashes (jars or boxes) by a work tool or put in a steel box for the bone to be.

1 shows a conventional image incinerator.

That is, the conventional cremation incinerator shown in FIG. 1 includes a main combustion chamber 120 in which a burner 110 is installed and incineration of a fluid by substantial combustion, and an induction furnace 130 for flowing exhaust gas of combustion gas. In the induction furnace 130, a dust filter 140 for filtering exhaust gas is disposed.

At this time, Figure 1a shows a middle co-current cremation incinerator (100a), Figure 1b shows a middle counter current cremation incinerator (100b), the difference is in the induction direction of the induction furnace 130, For example, in FIG. 1A, the combustion (exhaust) gas G is exhausted to the main combustion chamber 120 in the opposite direction of the burner 110, and in FIG. 1B, the combustion gas G is circulated in the main combustion chamber and the main combustion chamber at the burner side. It is exhausted to 120.

On the other hand, since the exhaust gas G is circulated by the discharge pressure of the burner in the main combustion chamber 120, the exhaust gas G increases the residence time of the combustion incinerator of the combustion gas than in FIG. It is a more preferable structure in terms of.

However, in the cremation incinerator 100 of FIG. 1, since the exhaust gas G is exhausted immediately after being burned once in the burner, air pollution such as carbon monoxide (Co) or nitrogen oxide (NOx) due to incomplete combustion. There was a problem that the material is released as it is.

On the other hand, Figure 2 shows another conventional cremation incinerator, such a cremation incinerator 100 'adjusts the direction in which the burner 110 is installed, the combustion (exhaust) gas generated in the main combustion chamber 120 ( G) passes through the exhaust gas passage chamber 140 installed in the lower part of the main combustion chamber 120, thereby providing the advantage that the furnace residence time of the exhaust gas is longer than that of the cremation incinerator 100 of FIG.

However, in this case, since the exhaust gas G is exhausted as it is, there remains a problem that air pollutants such as carbon monoxide (Co) or nitrogen oxide (NOx) are released as it is due to incomplete combustion as shown in FIG.

Next, FIG. 3 illustrates another conventional cremation incinerator 100 ″, in which case the exhaust gas induction furnace 130 ′ provided at the upper portion of the main combustion chamber 120 is extended to further extend the residence time of the combustion gas. In addition, by installing the auxiliary burner 150 in the improved induction furnace 130 'and simultaneously burning the exhaust gas in the induction furnace 130', carbon monoxide (Co) or nitrogen oxide due to incomplete combustion It is to some extent blocked the release of air pollutants such as NOx into the atmosphere.

However, in another conventional cremation incinerator 100 ″ of FIG. 3, the residence time of the exhaust gas G through the induction furnace 130 ′ is extended to reduce the environmental pollution problem, but the actual exhaust gas is induced. Since it is not stored in the furnace 130 'and is exhausted as it is, its energy saving effect was insignificant.

That is, it is possible to reuse the sensible heat of the exhaust gas G exhausted through the induction furnace 130 ', but it is not practically helpful for the elevated temperature of the initial stage of the cremation, which requires the most energy consumption in the actual cremation incinerator, There is little reduction in energy consumption due to the initial temperature rise.

Accordingly, while reducing the energy consumption of the cosmetic incinerator, the thermal efficiency is increased, and energy saving and eco-friendly cosmetic incinerator are required in which less pollutants such as carbon monoxide (Co) or nitrogen oxide (NOx) are released into the atmosphere due to incomplete combustion.
