Description

Air-cooled side wall for incinerator}

The present invention relates to a sidewall for an incinerator, and more particularly, to an air-cooled sidewall for an incinerator.

Waste such as household or industrial waste is incinerated using an incinerator. In general, when garbage or waste is incinerated in an incinerator, non-combustible residues such as clinker are adsorbed on the fire wall. Normal operation of the grate cannot be expected.

The grate row of the incinerator is formed by a plurality of heat-resistant/abrasion-resistant metal grates supported by round rods to form one row. In this case, in order to prevent the refractory bricks of the inner wall of the incinerator from being worn or damaged due to adhesion of combustion by-products such as clinker, the side wall having a structure that can cover a part of the inner wall of the incinerator is placed on the outermost side of the fixed end. is mounted on

The fixed end is mounted on the fixed frame of the conveying device by the round bar for the fixed end, and the moving end is attached to the movable frame of the conveying device by the round rod for the moving end. It operates in such a way as to sequentially move the waste to the exit side while reciprocating back and forth between them. During the forward and backward reciprocation of the moving end, wear damage occurs at the contact portion between the lower end of the sidewall of the fixed end adjacent to the front and rear and the outermost grate of the moving end, as shown in FIG. 1, depending on the degree of wear (in FIG. 1). Refer to the red circle) The sidewall protrudes from its original position to the inside of the incinerator or begins to collapse, interfering with the operation of the grate. For the damaged sidewall grate, maintenance such as periodic replacement is required.

On the other hand, the conventional sidewall has a problem in durability after being installed on the fireproof wall of the incinerator. In other words, after installing the sidewall at the desired location of the fire wall inside the incinerator, the sidewall is deformed due to high heat when the incinerator is operated. After a certain period of time, the sidewall protrudes or collapses In addition to the problem, sidewall bursting frequently occurs (see red box in FIG. 2). In order to prevent this problem, an air cooling method is used to cool the sidewall by introducing cooling air from the bottom of the incinerator as a whole, but the cooling effect is not satisfactory, and in a situation where a higher standard sidewall installation is required recently, the sidewall There is a limit to implementing the cooling effect up to the top.

While doing so, the sidewalls 100 in both directions are connected to each other in the horizontal direction so as to be stacked in a stepwise manner.

The air-cooled sidewall 100 according to the present invention is an air-cooled sidewall that allows the injected cooling air to flow out to the air outlet 120 via the space 110, thereby cooling the lower part of the existing incinerator as a whole. Compared to the method, the cooling effect is significantly improved, and the durability period of the sidewall, which is reduced due to the low cooling effect, can be significantly increased.

The space portion 110 provides a passage for the injected cooling air, and is formed by opening the rear surface of the sidewall 100, that is, the surface facing the inner surface of the incinerator refractory wall F. The space portion 110 may be formed as a whole except for the edge of the rear surface of the side wall 100, for example, but when the space portion 110 is formed on the entire surface of the rear surface, the holding force and deformation resistance in the fire wall (F) Since this can be lowered, the partition wall 170 can be formed in the preferred embodiment of the present invention.

The partition wall 170 divides the space portion 110 and serves to minimize the decrease in deformation resistance due to the weakening of the rigidity of the sidewall 100 due to the formation of the space portion 110 .

The air outlet 120 is a passage through which the injected cooling air flows out of the sidewall 100 after passing through the space 110 . The air outlet 120 is formed on a part other than the rear surface, for example, as shown in the drawing, it may be formed on the side (thickness) of the side wall 100 having a certain thickness T, preferably It may be formed on the lower side of the sidewall.

It is preferable that the air discharged through the air outlet 120 communicates with the lower portion of the adjacent grate G.

FIG. 6 is a rear perspective view illustrating a flow of air flowing out through an air outlet in the sidewall shown in FIG. 3 by way of example.

Referring to FIG. 6 , since the air cooling the sidewall 100 can still cool the adjacent grate G, the air discharged through the air outlet 120 flows into the lower part of the adjacent grate G and It is preferable that the lower part of the side wall 100 is designed to communicate with the lower part of the grate (G) so that (G) can be cooled.

The air injection pipe 130 is a connection passage through which cooling air is injected into the space 110 of the side wall 100, and is installed in communication with the outside of the fire wall F. The supply of cooling air may be performed, for example, by operation of an air injection pump provided outside the incinerator, and a method of supplying the cooling air is not particularly limited.

At this time, the air injection pipe 130 is preferably formed on the upper side of the side wall (100). In addition, as described above, since the air outlet 120 is formed in the lower part of the side wall 100, the injected air can pass through the whole from the upper part to the lower part of the side wall 100, and the installed side wall ( 100), an effective cooling effect can be imparted to the sidewall regardless of the height.
