Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to bricks stacked in a heat storage chamber and a method of constructing the same.

A heat storage chamber is a hollow chamber filled with many bricks. After passing high-temperature gas such as exhaust gas and storing heat in these bricks, the ventilation gas is switched and low-temperature gas such as combustion air is passed through. This method applies heat to the bricks and recovers the heat.

The shapes of brick masonry can be roughly divided into chimney shapes, which allow gas to pass through vertically, and staggered shapes, which allow gas to pass through in a zigzag pattern. The former has low ventilation resistance, but has the disadvantage of poor heat transfer. Sasa, on the other hand, has good heat transfer but has the disadvantage of low ventilation resistance. The high-temperature gas that is passed through for heat recovery often contains dust, so in a staggered 1m tiled structure, ventilation resistance increases rapidly, and it is difficult to remove the accumulated dust, so chimney-shaped structures are generally used. It is considered good. However, the problem with the chimney shape is that it has poor heat transfer.

In addition, conventionally, bonded wires and roof tiles have often been used as bricks for the space in the heat storage chamber, but bonded bricks are not necessarily preferable as bricks for the space in the heat storage chamber and have many drawbacks, so instead of bonded bricks, electric melting is used. The use of cast bricks (electroformed bricks) has been proposed and has been used to some extent. Although electroformed bricks can solve the drawbacks of bonded bricks, they have the disadvantage of being expensive. Also, since it is difficult to process, there are many points that must be taken into consideration when constructing it.

In order to obtain a stable structure for heat storage chambers using electroformed bricks, it was discovered in 1986-5645 that electroformed bricks were modified into various shapes.
This method has been proposed in Japanese Patent Publication No. 0, Japanese Patent Publication No. 55-45885, etc. However, these proposals require several types of irregularly shaped bricks for one construction, are complicated in shape, are inconvenient to store and transport, and are easily damaged, and furthermore, cannot provide a stable construction structure. There is a problem.

An object of the present invention is to provide a brick for a heat storage chamber space that can constitute a chimney-shaped space structure that is stable and has good heat transfer in the heat storage room, and a method for constructing the same.

The brick for a heat storage chamber space according to the present invention has a main part having a dimensional relationship of length>height>width, and one end and intermediate part in the length direction of one side of the main part on the height x length side. The length of the two protrusions is different, and the length of the longer protrusion is different. The spacing between the two protruding parts is equal to or slightly smaller than this, and the spacing between the protruding part of the intermediate part and the longitudinal end of the main part without the protruding part is equal to the spacing between the two protruding parts. It is a brick characterized by being equal to or greater than ノ'so.

Preferred embodiments of the brick for use in a heat storage chamber according to the present invention are as follows.

(1) A small protrusion with the same height and width as the protrusion on both sides of the opposite side surface where the protrusion of the main part is not branched, at the bottom of the position facing the protrusion; It is a provision.

(2) The joint portions forming a right angle between the main portion, the protruding portion, and the small protruding portion are built up in a circular arc shape.

(8) The main portion, the protrusion, and the small protrusion are tapered in the height direction to reduce the width.

(4) The brick is an electroformed brick.

Furthermore, the method for constructing a brick for a heat storage chamber space according to the present invention uses the above-described brick for a heat storage room space according to the present invention, and combines a plurality of bricks to form a main part and a protruding part of a constant thickness. A brick layer is formed by arranging so as to form a large number of adjacent regular square holes with one side being the interval between the protrusions, which are partitioned by a wall partially having a communication hole, and a brick layer is formed on the brick layer. The bricks are stacked one after another by shifting the position from the bricks of the brick layer and stacking them over 2 to 4 bricks so that their main parts and protrusions overlap with the main parts or protrusions of the bricks in the lower layer. This construction method is characterized by

In a preferred embodiment of the method for constructing bricks for a heat storage chamber space according to the present invention, the plurality of bricks are arranged so that the protruding parts are in the same horizontal direction, the main parts are in a vertical straight line, and the intervals between the protruding parts are large. A vertical row of bricks is arranged to form a vertical row of bricks, and a row of vertical bricks similar to this one is placed next to the vertical row of bricks with protruding portions whose spacing between the main portions is approximately equal to the spacing between the protruding portions of the bricks. Bricks are placed one after another in a straight line horizontally to form a layer of bricks, and the bricks are placed on top of the brick layer so that the main part straddles the main part of the two bricks in the direction of the lower layer. The bricks of the present invention will be described below based on the drawings of the embodiments, in which the protrusions are oriented in the same direction or in the opposite direction to the protrusions of the lower brick, and the protrusions of the lower brick overlap.

Figure 1 is a perspective view of one embodiment, Figures 2 (a), (b), (
C), (d), and (θ) are plan views of different embodiments, respectively.

In the drawings, 1 is the main part. The main portion 1 has a dimensional relationship of length (l)>height (opening)>width (d). Width (d)
In the case of electroformed bricks, a value of 50w11 or less is generally sufficient. Projecting parts 2 and 8 are branched on one side surface of the main part 1 on the height x length side. The protrusion 2 branches from one end (including substantially one end) of the side surface in the length direction, and the protrusion 8 branches from the middle portion at a right angle (including substantially right angle) to the side surface and the top surface, respectively. The width and height of the protruding portion 2.8 are the same (including substantially the same) as that of the main portion 1, and the length m1n of each protrusion is different. The embodiment of FIG. 1 is m ) n. The distance l□ between the two protrusions 2.8 is approximately equal to the length m of the long protrusion 2, and is slightly longer than the length m of the long protrusion 2. Also, the distance l between the protruding part 8 of the intermediate part and the longitudinal end of the main part without the protruding part
, is approximately equal to or smaller than the interval 11.

In order to better understand the reason why the dimensional relationship between the main part and the protruding part is variously limited in the brick of the present invention, the basics of the construction method using this brick will first be explained based on FIG. 8.

The brick of the present invention is a brick that can be configured into a chimney-shaped cavity structure that is stable and has good heat transfer in a heat storage chamber, as described in the object section of the present invention.

That is, as shown in FIG. 8, a vertical hole with a cross-sectional area of 11×1 is partitioned by a wall with a thickness of d to form a chimney-shaped open space structure. However, as is well known, in such a structure, gas flows in a laminar flow and heat transfer is poor, so in the structure of the present invention, these walls are punched out in places to create lateral flow and to prevent turbulent flow. This is to improve heat transfer.

Therefore, in the brick shown in FIG. 1, the length m of the protrusion 2 is 11
The length n of the protrusion 8 must be shorter (in some cases, they may be equal)! , is shorter, and the length l of the leg of the main part 1 is shorter than l (in some cases, it is equal). means.

When the bricks of the present invention are combined and stacked blankly, it is possible to construct a brickwork structure with punchings in some places in the wall, the brickwork structure can be made stable, the bricklaying work is easy, and the individual The bricks are characterized in that they do not have a rough shape, are easy to manufacture, especially electroforming, and are convenient to transport and store.

The length m of the long protrusion 2 or 8 in FIGS. 2(a), (b) and (C) is shown to be equal to l, but it is indicated by a broken line that it may be shorter than l.

Next, another embodiment will be described based on FIGS. 2(d) and (e). In this brick, the protruding part 2.8 of the main part 1 has the same height h and width as the protruding part 2.8 at one or both of the positions facing the protruding part 2.8 on the opposite side where it is not branched. A small protrusion 4 of d is provided. Although the length p of the small protrusion 4 is short, its length p and the length m of the protrusion 2.8
The relationship of 1n will be described at the same time as the explanation of the construction method.Another example is shown in FIGS. 4(a), (b), (C), and (d).

In the bricks shown in FIGS. 4(a), 4(Q), and 4(a), the right-angled joints between the main portion 1, the protruding portions 2.8, and the small protrusions 4 are overlaid 5 in a circular arc shape. Although I used the term "overlay," it goes without saying that it is not something that is added later to the main part and protruding parts.
The built-up portion 5 is formed in a casting mold or a mold, and is formed integrally with the main portion, the protruding portion, etc. The built-up portion 6 prevents the occurrence of cracks in the vicinity of the joint between the main portion 1 and the protrusion 2.8 or the small protrusion 4. Further, when a vertical hole forming a chimney is formed, this corner also becomes a corner of the hole, and gas stagnates in this corner and hardly moves. Therefore, the formation of the built-up portion 5 promotes smooth gas flow.

In the bricks shown in Fig. 4(b), (C), and (d), the main part 1, the protruding part 2.8, and the small protrusion are tapered in the height direction and reduced in width (a part of the taper is 6).

Due to the formation of the tapered part 6, when the main part 1 or the protruding part 2.8 of the bricks are stacked one on top of the other, the gas flowing in a laminar flow along the wall as shown in FIG. This creates a turbulent flow that improves heat transfer between the gas and the bricks.

Although the brick structure of the present invention can be effective as a bonded brick, it can also exhibit excellent effects when applied to electroformed bricks.

In the above, although not specifically explained, the brick of the present invention also requires fitting means, such as the upper and lower surfaces of the main part and the protrusion, in order to improve the connection with other bricks and stabilize the structure. Naturally, a protrusion and a recess that fits into the protrusion are provided.

Next, a method for constructing a brick for a heat storage chamber according to the present invention will be described. In the construction method of the present invention, first, the bricks of the present invention are used and combined as already partially described in the explanation referring to FIG. A brick layer is formed by arranging the bricks so as to form a large number of adjacent 11 x 1 square holes partitioned off. The F-shaped brick or the brick having a small protrusion in the F-shape of the present invention can be made into a brick layer having a large number of adjacent square holes as described above by using various methods or by combining several methods. I can do it. In FIG. 8, one brick in each method is shown by an F-shaped solid line.

Furthermore, the second and eighth brick layers are constructed in the same manner. However, the bricks are arranged over 2 to 4 bricks at different positions from the bricks in the lower layer so that their main parts and protrusions overlap with the main parts or protrusions of the bricks in the lower layer. This arrangement table may be the same as or different from the underlying arrangement method,
Alternatively, a combination of several methods may be used. By using the same method as the lower layer, you can step up to 98 to 4 bricks by straddling the two bricks on the lower layer.

FIG. 5(a) shows how various types of bricks are combined in one brick layer. One brick is shown by a double-shaped solid line. FIGS. 6(b), (C), and (d) show an example of a method in which upper layer bricks are superimposed on lower layer bricks. The lower layer bricks are shown with solid lines, and the upper layer bricks are shown with broken lines.

Furthermore, specific examples of the construction method according to the present invention are shown below.

In FIG. 6, a part of an embodiment of one brick layer is shown by a solid line with 2 bricks per row x 8 rows. That is, a plurality of (2 in Fig. 6)
Please show only one item. ) A vertical row of bricks I is formed so that the protrusions are in the same horizontal direction, are in line with the main force I, and the protrusions are spaced equally, that is, all are l. A similar vertical row of bricks (2) is placed horizontally next to the next row of bricks so that the interval between the main parts is approximately equal to the interval l between the protruding parts of the bricks,
The protrusions are arranged horizontally in a straight line, and in the same manner, the brick rows (1) are arranged to form a brick layer. This brick layer is 11x separated by walls of thickness d as shown in Figure 8.
A large number of holes 7 having a size of l, are formed. However, in the embodiment shown in FIG. 6, the protrusion 8 is shortened, so
In the drawing, the upper and lower holes 7 are in communication. Similarly, when the protruding part 2 or the leg part of the main part 1 is shortened, adjacent holes 7 at the core are communicated with each other 8 Stacking the main part of the bricks on top of this brick layer There are two methods. One brick A and one brick B are shown in broken lines to represent each method in a smaller size than they actually are. ' That is, the main parts of bricks A and B are straddled over the main parts of the two lower bricks, and the protruding parts are in the same direction (A brick) or in the opposite direction (B brick) as the protruding part of the lower brick. ), stack the bricks so that they overlap the protruding parts of the lower bricks. After that, bricks A or B are stacked to form the next layer of bricks. The communication points of the holes 7 in the first layer in FIG. 6 are closed in the second layer, and communication occurs at other points. In this way, by shortening the protrusions 2.8 and the legs of the main part 1, it is possible to alternately create individual holes 7 communicating with each other, creating a lateral flow of gas and generating turbulence. In addition, the bricks in the upper layer are placed on top of the two bricks in the lower layer with their main parts aligned, and their protruding parts press down on that brick or the protruding parts of adjacent bricks, so the brick stacking is stable. Furthermore, if the protrusions and recesses formed on the upper and lower surfaces of the bricks are fitted together, it will be even more stable.

FIG. 7 shows an example of a brick layer constructed using bricks having small protrusions in the same manner as in FIG. 6. This figure shows two rows of two bricks per row. The construction method is exactly the same as in the case of FIG. Although FIG. 7 only shows brick A in which the protrusion of the upper brick is oriented in the same direction as the protrusion of the lower brick, it may be made in the same manner as brick B in FIG. When the brick has this small protrusion, it becomes more stable, especially when stacking bricks using the brick A method.

When creating a small protrusion on a brick, the length of the protrusion, that is, the longer protrusion, must be shortened, and the short protrusion must be shortened so that a sufficiently large continuous hole is formed. It needs to be shortened to .

Furthermore, in the construction method of the present invention, as shown in FIG. 5, the main parts of the lower layer and the upper layer may not be overlapped, but the protruding parts may be stacked on the main part, and the main parts may be stacked on the protruding parts.

The brick for a heat storage chamber and its construction method according to the present invention are constructed as described above. As described above, the brick of the present invention has a simple shape and can be easily manufactured, particularly by electroforming, and is convenient for storage and transportation. Furthermore, using the bricks of the present invention, and even using only one type of brick, it is possible to easily construct a chimney-shaped regenerator brick structure having lateral ports at various places, and this structure is extremely stable. Additionally, the passing gas is made turbulent by the lateral communication ports, which improves heat transfer between the bricks and the gas. Therefore, the brick of the present invention and its construction method have a value of 0.
