Incinerator to prevent clinker attachment {INCINERATOR FOR PREVENTING CLINKER ATTACHMENT}

The present invention relates to an incinerator for preventing clinker attachment, and more particularly to an incinerator for preventing clinker attachment from being attached to a side wall of a combustion chamber in an incinerator.

As is well known, the destruction of the natural environment caused by wastes discharged from households or industrial sites is becoming more serious as human society is civilized and industrialized.

Therefore, a method of incineration of wastes that cannot be recycled through an incinerator has been proposed.

Conventional incinerators for incineration of non-recyclable wastes include combustion chambers for drying and burning wastes.

An inlet for injecting waste is formed at one upper end of the combustion chamber, and an outlet for discharging the remaining incineration ash is formed at the lower side of the combustion chamber through the grate.

Incinerators may be classified into various types according to the type of grate, but may be classified into a pusher type and a moving grate type.

In particular, in the case of a pusher-type grate, the fixed grate and the moving grate are arranged alternately, and the movable grate moves the waste by reciprocating between the fixed grate.

Therefore, the pusher-type grate is divided into a drying stage for drying, dry distillation and gasification of the waste, a combustion stage for burning the gasified waste in the drying stage, and a post-combustion stage for burning the remaining carbon after combustion. However, the temperature increases in the order of post-combustion.

As the waste is incinerated, the inorganics in the solids melt, forming clinkers.

Over time, the clinker cools down in contact with the combustion air and hardens to the surface of the inner brick.

As a result, damage to the grate and damage to the fireproof wall, the incineration rate is reduced, the incinerator is impossible to operate due to the accumulation of combustion products, there is a problem that the post-treatment cost increases.

By filling between the two sides, the side flange portion 52 is not directly exposed to the high temperature heat when the combustion chamber 20 is a high temperature can prevent the side flange portion 52 from being deformed by the heat. .

In addition, by forming a large area portion 44 in the first inner brick 41, to minimize the gap between the first inner brick 41 to minimize the high temperature heat flow into the side flange portion (52). can do.

The chamber forming part 54 is coupled to the rear of the brick support part 51 to form a side wall of the air chamber 55.

The chamber forming part 54 may form the air chamber 55 as large as the size of the first inner brick 41 as in the present embodiment. Unlike the present embodiment, the chamber forming part 54 in the up, down, left and right directions ( 54 may be in communication with each other to form an air chamber 55 corresponding to the size of the plurality of first inner bricks 41.

The brick fixing part 56 is coupled to the rear of the chamber forming part 54 and serves to fix the first inner brick 41.

The brick fixing portion 56, the support plate 57 is coupled to the chamber forming portion 54, and the socket is mounted to the support plate 57 to protrude in the direction of the first inner brick (41) ( 58 and a bolt member 59 penetrating the first inner brick 41 and coupled to the socket 58.

Inside the socket 58, a screw thread for coupling the bolt member 59 is formed.

In addition, a seating groove 45 in which the bolt member 59 is seated is formed on a front surface of the first inner brick 41, and the depth of the seating groove 45 is defined by the bolt member 59 being the socket ( 58 is formed deeper than the height of the protruding height of the bolt member 59, the seating groove 45 is filled with a refractory insulating material (70).

By forming the mounting groove 45 as described above, it is possible to prevent the bolt member 59 from being directly exposed to high heat, such as the side flange portion 52.

The head of the bolt member 59 disposed in the seating groove 45 is a flow preventing piece for holding the fire-resistant insulating material 70 is filled in the seating groove 45 so as not to be separated from the seating groove 45 59a is formed.

Hereinafter, an operation process of the present invention having the above-described structure will be described.

As the waste disposed in the combustion chamber 20 is burned in a high temperature state, the molten material moves with the gas through the gas discharge port 30 and then adheres to the side wall of the combustion chamber 20 and flows or burns. While being attached to the lower side wall of the combustion chamber (20).

The molten material attached to the first inner brick 41 forming the side wall of the combustion chamber 20 is cooled while being in contact with the air for combustion to change into a rigid clinker.

At this time, in the present invention, the air introduced into the air chamber 55 through the air suction hole 61 of the heat insulating member 60 is in direct contact with the rear surface of the first inner brick 41 and the first inner portion. The brick 41 is cooled.

Accordingly, the molten material attached to the surface of the first inner brick 41 is changed into a hard clinker by the cooled first inner brick 41.

However, at this time, since the coefficient of thermal expansion of the clinker attached to the first inner brick 41 and the first inner brick 41 are different, the clinker attached to the first inner brick 41 is the first inner brick ( It is separated and separated to the surface of 41).

By the incinerator of the present invention having the structure as described above, by preventing the clinker is attached to the side wall of the combustion chamber 20, to reduce the damage to the grate and the fire wall, increase the incineration rate, the operation of the incinerator is stopped by the clinker Can be prevented.

The first discharge hole 46 is formed in the first inner brick 41 in the first embodiment, but the first discharge hole is not formed in the second inner brick 42 in the second embodiment.

In addition, a second discharge hole 66 through which air introduced into the air chamber 55 is discharged is formed in the heat insulating member 60.

Therefore, the air introduced into the air chamber 55 through the air suction hole 61 collides with the rear surface of the second inner brick 42 to cool the second inner brick 42, and then It is discharged to the outside through the two discharge holes (66).

At this time, the air chamber 55 is formed by a plurality of sizes of the second inner brick 42, so that the air suction hole 61 is located in the lower position and the second discharge hole 66 is located in the upper portion Ensure the air flows smoothly.

That is, as shown in FIGS. 7 and 8, the lower portion of the chamber forming portion 54 positioned at the upper portion is opened and the upper portion of the chamber forming portion 54 positioned at the lower portion is opened to form the chamber formed at the upper portion. The portion 54 and the chamber forming portion 54 positioned below are in communication with each other.

Therefore, as shown in FIG. 8, air introduced through the suction hole formed in the second inner brick 42 located below is introduced into the air chamber 55 to cool the second inner brick 42. After being discharged to the outside through the second discharge hole 66 formed in the second inner brick 42 located above.

At this time, the temperature of the air discharged through the second discharge hole 66 is to maintain less than 100 degrees.

Other matters are the same as in the first embodiment, and description thereof will be omitted.
