Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to household and general incinerators, and more particularly, to a furnace wall structure devised so as to reduce thermal shock and mechanical shock applied to the furnace wall and facilitate manufacturing.

[0002]

[Prior art]

 Conventionally, the furnace wall of this type of incinerator is mainly made of iron or concrete, and in the former case, rust occurs in a short period of time, which damages the surrounding living environment and has a short life. was there. In the latter case, the wall thickness of the furnace wall becomes unnecessarily thick and the weight increases, and it also has the drawback of cracking when repeatedly subjected to expansion and contraction stress. In order to eliminate such drawbacks, it is effective to use a structure in which furnace walls made of materials such as chamotte, clay, and diatomaceous earth are combined in a composite manner, but one furnace wall having different thermal expansion coefficients is effective. There is a drawback in that dimensional accuracy is extremely strict and sophisticated technology is required to insert into a furnace wall that can be inserted into other furnace walls, resulting in extremely high cost and impracticality.

[0003]

[Problems to be solved by the device]

 This invention was made in order to eliminate the drawbacks described in the prior art, and reduces the thermal shock and mechanical shock to the furnace wall, making it possible to fabricate an incinerator consisting of a complex furnace wall, which was difficult in the past. It is intended to be easy and practical.

[0004]

[Means for Solving the Problems]

 A buffer layer made of fiber members such as carbon fiber, ceramic fiber, metal fiber, shape memory fiber, or carbon fiber, ceramic fiber, metal fiber, shape memory between the furnace inner wall having heat storage property and the furnace outer wall having heat insulation property. A buffer layer made of a fiber member such as a fiber and having a slit is interposed.

The inner wall of the furnace is composed of a block member formed by attaching a buffer layer made of the fiber member or a buffer layer made of the fiber member and having a slit to the back surface.

The outer wall of the furnace is composed of a buffer member made of the fiber member or a block member made of the outer wall of the furnace made of the fiber member and having a slit buffer layer attached to the inner surface thereof.

[0007]

[Action]

 The buffer layer made of the fiber member or the buffer layer having the slit made of the fiber member absorbs the displacement due to the thermal expansion or contraction of the furnace wall, and alleviates the thermal shock applied to the furnace wall. Further, the buffer layer made of a fiber member or the buffer layer made of a fiber member and having a slit absorbs mechanical impact force such as vibration applied to the furnace wall. By providing slits in the buffer layer, it is possible to absorb and mitigate larger thermal shocks and mechanical shocks.

When the furnace itself is large, the temperature of the furnace can be controlled by making the electrically conductive fiber member such as carbon fiber have the heat generating property and the heat absorbing property. In addition, the buffer layer made of the shape memory fiber member shall be set so that the original shape of the shape memory fiber member returns to the original shape at the temperature at which the force exerted on the furnace wall from inside and outside the furnace is maximized. Thereby, the strength of the furnace wall can be reinforced.

【Example】

 A drawing showing an example of an embodiment of the present invention will be described. For example, in a furnace wall of an incinerator 12 including an inlet 9 for combustible wastes, a chimney 10, legs 11, etc., fine particles of diatomaceous earth, etc. A buffer layer 3 made of a fiber member such as carbon fiber, ceramic fiber, metal fiber or shape memory fiber between a furnace inner wall 1 made of ceramics and having heat storage properties and a furnace outer wall 2 made of heat-resistant clay, chamotte or the like having heat insulation properties. Alternatively, a buffer layer 3 ′ made of a fiber member such as carbon fiber, ceramic fiber, metal fiber, shape memory fiber and provided with slits 4 is interposed.

Further, in order to efficiently perform the manufacturing and assembling, at the manufacturing stage, the slits 4 made of the block member 5 or the fiber member, which is divided and the buffer layer 3 made of the fiber member is attached to the back surface, are formed. It is also possible to form the block member 6 by attaching the provided buffer layer 3 ′ to the back surface, and assemble the block member 6 and the like to form the furnace inner wall 1 having heat storage properties.

In order to efficiently perform manufacturing and assembling, a buffer member provided with a slit 4 made of a block member 7 or a fiber member which is divided at a manufacturing stage and a buffer layer 3 made of a fiber member is attached to an inner surface thereof. The furnace outer wall 2 having heat resistance may be configured by forming a block member 8 formed by attaching 3'to the inner surface, and assembling the block member 8 and the like. In addition, in order to enhance the function of the fiber member forming the buffer layers 3 and 3 ′, protrusions, stripes, voids or the like may be provided on the surface of the fiber.

[0012]

【effect】

 Since the present invention is configured as described above, it has the following effects.

Since the inner wall of the furnace has a heat storage property, the temperature in the furnace chamber does not suddenly drop even if the amount of combustion products in the furnace decreases, so that stable combustion efficiency can be maintained.

Since the outer wall of the furnace has a heat insulating property, the surface temperature can be maintained to such an extent that the human body is not damaged even if it contacts.

Since the furnace wall has a structure capable of absorbing thermal shock and mechanical shock, it is possible to prevent cracking and damage of the furnace wall.

Since the outer wall of the furnace does not rust, it does not spoil the aesthetics of the surroundings.

It is economical because it is easy to process and assemble, the cost required for it can be reduced, and mass production is possible.

By imparting electrical conductivity to the fiber member forming the buffer layer, it is possible to give heat generation and heat absorption to the furnace wall, so that it can be used for a furnace that handles huge heat such as a large incinerator and a blast furnace. .

When the shape-memory property is imparted to the fiber member forming the buffer layer, the furnace wall can be reinforced at a predetermined furnace temperature. This device has the remarkable effects as described above and has high industrial utility value.
