ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a refuse incinerating oven, more particularly to a refuse incinerating oven which generates combustion exhaust with less toxic content.
2. Description of the Related Art
In recent years, industrial waste and refuse are usually disposed by incineration. During incineration, the resulting combustion exhaust is released to the atmosphere via a stack of the incinerator. However, the combustion exhaust usually contains toxic substances, such as dioxines, and thus causes serious air pollution.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a refuse incinerating oven which generates combustion exhaust with less toxic content.
Accordingly, the refuse incinerating oven includes at least one refuse loading car adapted for loading refuse thereon. A furnace body has a car inlet, a car outlet, a lower combustion chamber disposed between and communicated with the car inlet and the car outlet, and an upper combustion chamber disposed above and communicated with the lower combustion chamber. Conveying means is provided for conveying the refuse loading car through the furnace body from the car inlet to the car outlet. Igniting means is provided in the lower combustion chamber of the furnace body for igniting the refuse loaded on the car when the car is conveyed through the furnace body. Gas heating means is provided in the upper combustion chamber for heating combustion exhaust generated when burning the refuse in the lower combustion chamber. A spraying tank is communicated with the upper combustion chamber for receiving the combustion exhaust. Spraying means is provided in the spraying tank for spraying water mist to the combustion exhaust in the spraying tank so as to generate aerated water in the spraying tank. Cooling means is connected to the spraying tank for cooling the aerated water and the combustion exhaust flowing from the spraying tank. Reservoir means is connected to the cooling means for receiving the aerated water and the combustion exhaust flowing from the cooling means. A waterfall tank has a lower end communicated with the reservoir means, and an upper end disposed at an elevation higher than that of the reservoir means. Pumping means is provided for pumping the aerated water from the reservoir means to the upper end of the waterfall tank and for releasing the aerated water at the upper end of the waterfall tank so as to generate inside the waterfall tank a downwardly cascading water stream that falls back into the reservoir means via the lower end of the waterfall tank. An exhaust port unit is connected to the upper end of the waterfall tank for sucking the combustion exhaust from the waterfall tank and for releasing the combustion exhaust.
