The present invention relates to a waste incinerator for incineration of various wastes, in particular to improve the incinerator internal structure to improve the incineration efficiency.

The conventional waste incinerator internal structure has a shape as shown in FIG. 1 of the accompanying drawings.

First, the inside of the incinerator is largely divided into the primary combustion chamber 1 and the secondary combustion chamber 2 so that the residence time of the combustion gas is increased in the primary combustion chamber 1 to increase the combustion efficiency.

At this time, in the primary combustion chamber 1, air supply pipes 3 for supplying air to the waste to be burned are installed in the uprights to both sides, respectively, and nozzles for injecting air into the air supply pipes 3. (4) are arranged in a single shape along the air supply pipe (3).

And the secondary combustion chamber (2) side is provided with a dam-shaped overflow (5) so as to have a certain height from the lower surface of the combustion chamber, so that the combustion residence time is increased while the burned gas passes through the overflow (5).

However, in the conventional incinerator internal structure having the structure as described above, when the waste inlet 6 is opened to incinerate the waste and the waste is continuously introduced into the incinerator, the waste is accumulated inside and the lower portion of the air supply pipe 3 As some of the nozzles 4 located on the side are blocked, sufficient combustion is not achieved, and the air injected through the nozzles 4 of the air supply pipe 3 is sprayed only in a certain direction so that the primary combustion chamber 1 Because of insufficient turning inside, the unburned gas remained on the upper side of the primary combustion chamber 1, causing a decrease in the incineration capacity.

In addition, since the air supply pipe 3 located on the front side from the waste inlet 6 is arranged to be spaced apart at a certain interval, the combustion gas flows back to the waste inlet side while the combustion gas remains in the space between them. This caused the air to be polluted by the leakage of harmful gases, and when the worker opened the waste inlet 6 for the waste input, the combustion flame escaped to the waste inlet 6 side and severely burned the worker. There is also a safety problem.

In addition, the overflow section 5 on the side of the secondary combustion chamber 2 is provided in a simple form of a dam phenomenon, and thus a sufficient residence time of the combustion gas cannot be extended, and unburned gas is discharged to the outside of the incinerator as it is, thereby causing air pollution. And severe odor occurrence.

The present invention is to solve the above-mentioned conventional problems to improve the internal structure of the incinerator to increase the work stability and maximize the improvement of combustion efficiency.

According to the aspect of the present invention for achieving the above object, an inverted U-shaped air supply pipe is installed at the waste inlet face of the primary combustion chamber in the incinerator, and a barrier wall is installed between the primary combustion chamber and the secondary combustion chamber. On the blocking wall as one side together It forms a combustion passage of about the size and is installed by the burner which is installed near the combustion passage and re-burns on the secondary combustion chamber side.

When described in more detail with the accompanying drawings showing an embodiment of the present invention configured as described above as follows.

2 is a perspective view schematically showing the entire interior of the incinerator of the present invention.

First, in order to introduce external air into the primary combustion chamber 1, an air supply pipe 3 having up to two nozzles 4 is installed upright on both inner sides of the primary combustion chamber 1, which is the same as the conventional structure of FIG. Is omitted.

In the present invention, an inverted U-shaped air supply pipe 13 is additionally provided on the surface where the waste inlet 6 on the inlet side of the primary combustion chamber 1 is located.

In addition, the air supply pipe 13 was provided with a plurality of nozzles 14 in which the air injection direction is directed into the combustion chamber along the air supply pipe 13.

The additional air supply pipe 13 installed as described above allows the combustion gas flowing back to the waste inlet 6 side while smoothly turning unburned gas existing in the upper portion of the primary combustion chamber 1 due to incomplete combustion. To improve the combustion efficiency.

At this time, the conventional air supply pipes (3) installed in the primary combustion chamber (1) and the nozzles (4), 14 formed in the inverted U-shaped air supply pipe (13), which is additionally installed, the simple one-shaped It is also preferable to arrange in parallel to have different injection angles in a zigzag form instead of an arrangement so as to further improve the combustion efficiency.

In addition, a blocking wall 15 for blocking the combustion chamber is provided at a portion divided into the primary combustion chamber 1 and the secondary combustion chamber 2, and one side of the blocking wall 15 is a combustion gas passage ( Form 15a).

At this time, it is possible to form a plurality of the combustion gas passage (15a) in a variety of forms, in the present invention is approximately of the blocking wall (15) It was formed in the form of a rectangle on one side interruption to a size.

Accordingly, the combustion gas generated from the primary combustion chamber 1 flows through the combustion gas passage 15a to the secondary combustion chamber 2 in the direction of the arrow in the drawing.

Moreover, in this invention, in order to burn again the unburned gas in the combustion gas which passed this combustion gas path 15a, the burner on the side wall of the secondary combustion chamber 2 of the point which passed the combustion passage 15a is burned. (16) was installed.

The burner 16 is installed so as to have a vertical shape with respect to the flow of unburned gas passing through the combustion passage 15a, and reburns the unburned gas and directs the flow of the reburned gas to the stack side. By inducing the discharge flow, the combustion efficiency of unburned gas is greatly increased.

As such, the present invention forms an air wall by installing an additional air supply pipe on the waste inlet surface inside the primary combustion chamber to form an air wall, thereby suppressing the backflow of the combustion flame toward the waste inlet generated in the conventional structure, and allowing gas flow. The combustion efficiency is improved by improving the combustion efficiency, and at the same time, a barrier wall having a combustion gas passage is installed between the primary combustion chamber and the secondary combustion chamber so that the combustion gas escapes through the combustion passage, As the reburn is made, there is an effect of maximizing the combustion efficiency without the generation of unburned gas.
