The present invention relates to a horizontal rotary heating device for heat-treating a liquid or a substance which is a mixture thereof.

[0002]

2. Description of the Related Art In the process industry of economically supplying useful substances to society by utilizing physical, chemical and biological changes, raw materials and the like are in the form of powder and granules at room temperature.
Some generate a large amount of filter cake, slurry, or viscous liquid substances. As a conventional technique for heating such a substance to perform a physical / chemical change to obtain a useful intermediate material or product, there is a horizontal rotary furnace for performing indirect heating. As an example, an apparatus as shown in FIG. 18 is widely used.

In the apparatus shown in FIG. 18, reference numeral 1 'denotes a rotary cylinder made of a heat-resistant metal plate. The rotary cylinder 1' is supported at both ends by bearings 3 ', and has a center slightly inclined with respect to the horizontal. It is adapted to rotate around an axis 2 '. The raw material to be heated is fed into the vicinity of an end on the high position side of the rotary cylinder 1 ′ through a raw material inlet 4 ′ provided at one end of the rotary cylinder 1 ′, and then directed downward. It turns into a layer and rolls with the rotation of the rotary cylinder 1 ′, and slowly moves sequentially toward the other end on the lower position side.

[0004] The rotary cylinder 1 'is generally surrounded by a concentric non-rotating outer cylinder 6', and high-temperature combustion gas is supplied from a supply port 5 'provided at a low position side.
Flows through an annular flow path 7 ′ formed between the
The air is exhausted from the outlet 8 'provided at the high position side. Then, the combustion gas heats the rotary cylinder 1 'while flowing through the flow path 7'. The thermal energy transmitted to the rotary cylinder 1 'heats the rolling material at the bottom thereof to a required temperature. The steam or gas in the rotating cylinder 1 'generated by the heating is guided to the next step from the outlet 10' through an opening 9 'provided at the high position end of the rotating cylinder 1'. On the other hand, the solid which has lost the components which evaporate and evaporate due to the heating and has become a powder and granular form is rotated from the lower end of the rotary cylinder 1 ′ through the hood 11 ′ with the rotation of the rotary cylinder 1 ′ and the powder and granular material discharge port 'To fall.

[0005]

However, the above-described conventional apparatus has the following problems in performing the intended heating and separation of the product safely and continuously without polluting the environment. .

(A) <Fusion of feedstock> Many of the above-mentioned feedstocks and the like often become liquid during heating and heating. In such a temperature range, a trouble that is stuck to the inner surface of the rotating cylinder and hinders stable operation is likely to occur. In addition, slurry
A similar problem occurs if the viscous liquid raw material is supplied as it is. To cope with this, the powdery and granular substances that have been processed are mixed beforehand and then sent to the rotary cylinder. However, there is also a problem that the fusion is easy due to the slow progress.

(B) <Leakage of generated steam and gas> The rotating rotating cylinder must be sealed at both ends in order to prevent leakage of internal steam or gas. In general, a material having a large thermal expansion is used. For example, if the high position end of the rotary cylinder 1 ′ is fixed in the axial direction, the low position end of the rotary cylinder 1 ′ is thermally expanded during heating. Large displacement in the axial direction, which makes it difficult to complete the seal with the hood 11 '. This is a problem particularly when the generated steam / gas contains harmful components. Further, since both ends of the rotary cylinder are connected to the line of the next process by separate pipes, the rotary cylinder 1 '
From the imperfect seal at the lower end of the vehicle can lead to immediate explosion and is dangerous.

(C) <Thick rotating cylinder> The rotating cylinder 1 'in FIG. 18 is heated by the combustion gas and becomes high temperature, so that its strength is remarkably reduced. In this state, it is necessary to make the thickness of the rotating cylinder 1 ′ sufficiently large in order to make the structure sufficiently safe against the stress when rolling a heavy material into the rotating cylinder supported at both ends, resulting in high cost. A large amount of heat-resistant material is used, and a material having a large rotational driving force is required.

(D) <Small filling ratio> The rotating cylinder 1 'in FIG. 18 is advanced downward by rolling the layer of the granular material by rotation about a central axis slightly inclined with respect to the horizontal. The ratio of the volume of the granular material layer to the volume of the rotary cylinder, that is, the occupancy is about 10 to 15%, which is quite small. If a weir is formed at the outlet of the rotary cylinder and the inclination angle of the central axis is reduced, the occupation ratio of the granular material in the rotary cylinder space can be increased, but the rotation of the rotary cylinder causes the rotation of the powder layer. Only the surface in contact with the cylinder and the granular material near the surface of the granular layer become insufficient, and the mixing and heating of the granular material near the center of the granular layer become insufficient.

[0010] The present invention solves the problem of the conventional apparatus and, when heating raw materials and the like indirectly, has a high filling rate and is safe, stable and highly efficient continuous operation without causing environmental pollution. It is an object of the present invention to provide a horizontal rotary heating device which can be manufactured and has a low construction cost.

[0011]

According to the present invention, there is provided a rotatable cylindrical body having a rotation axis substantially horizontal and having an opening at at least one end in the axial direction, and an interior of the cylindrical body. A partition wall having a flat surface substantially parallel to a plane including the axis dividing the space into a plurality of spaces, and a plurality of guide plates attached to the partition wall so as to be arranged in an axial direction inclined with respect to the axis. In the horizontal rotary heating device, which has a granular mass as a substance to be subjected to the heat treatment, is fed through the opening, and is taken out after the heat treatment, a part or all of the partition wall is provided with a gas passage. As a space, a gas blast hole or fumarolic plate is provided on a part or whole surface of the partition wall surface, and necessary for physical change or chemical reaction of the granular lumpy solid in the granular lumpy solid layer in contact with the surface. Gas can be blown from the above-mentioned blowholes It is achieved by the.

[0012]

The granular solid which is to be heat-treated is supplied into the cylindrical body from the inlet, and the cylindrical body is rotating around the axis. After being lifted to one side by one side of the partition wall, it falls.
At this time, the granular solids slide down while being guided by the guide plate. Therefore, the guide plate advances in the inclined direction of the guide plate while sliding down from the upper end to the lower end. The layer of the granular solid in the cylindrical body is in contact with the surface of the partition wall until it is lifted to one side by one surface of the partition wall and slides down, so that a plurality of layers provided on the surface are provided. The gas ejected from the fumaroles or fumaroles flows through the solid granular layer and diffuses to the surface of each particle. As a result, a physical change or a chemical reaction between the granular solid and the gas rapidly proceeds, and the time required for the heat treatment is significantly reduced.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

<First Embodiment> In FIG. 1, a cylindrical body 2 is rotatably supported around a shaft 1 by a bearing (not shown). The cylindrical body 2 has, at one end, an inlet 2A for a powdery solid as a raw material to be subjected to heat treatment, and an outlet 2B at the other end. The tubular body 2 extends along the axis 1 and, when in the illustrated rotational position, has a plurality of internal spaces by a hollow partition wall 3 positioned parallel to the paper surface, and in the illustrated case, two internal spaces by one partition wall 3. An internal space is formed. An air supply pipe 4 for gas such as air is connected to the left end of the partition wall 3 to feed gas into the hollow space of the partition wall 3. The gas is blown into the inside of the cylindrical body 2 through a plurality of blow holes 5 provided on a part or the whole surface of the partition wall 3. A plurality of guide plates 6 are arranged on both surfaces of the partition wall 3 so as to be inclined in the same direction in FIG. The shape, number and angle of the guide plate 6 are appropriately determined depending on the heat treatment conditions.

FIG. 2 is a partially cutaway perspective view for explaining the partition wall 3 and the guide plate 6 shown in FIG. 1, and an arrow 7 indicates a direction in which gas is supplied. The supplied gas passes through the space inside the partition wall 3 and is blown out from the plurality of blow holes 5.

The bleed holes 5 provided on a part of or the entire surface of the partition wall are not necessarily limited to those shown in FIGS. 1 and 2, but may be, for example, flared holes arranged in an equilateral triangle. The shape itself can be various shapes. For example, a slit shape may be used. Fig. 3
The partition wall is formed by the two plates 8 and 10, the opening 9 is formed in the inner plate 8, the wire mesh or the porous plate 11 is attached, and the partition wall is formed on the wire mesh or the porous plate 11. Further, as shown in FIG. 3, an outer plate 10 having a plurality of blast holes 5 may be stacked. In that case, the outer plate 1
0 may be omitted.

FIG. 4 is an explanatory view showing the state of movement of the granular solid in the rotary heating apparatus of FIG.

Considering the case where the cylindrical body 2 is rotating clockwise as viewed from the left end side in FIG. 1, a powdery solid formed in the cylindrical body 2 in FIG. The state of the layer is as shown in state [I] of FIG. In FIG. 4,
C and D denote the two cylindrical body internal spaces separated by the partition wall 3, and 12 and 13 denote the granular solid layers existing in the spaces C and D, respectively.

Rotation by 90 degrees from the state [I] in FIG. 4 results in a state [II], in which the gas ejected from the inside of the partition wall 3 through the blast holes 5 is in the powder-globular solid layer 12 in the space C. Circulates, so that the solid and gas in the layer are in effective contact with each other. When the partition wall 3 is further rotated by about 45 degrees or more, the granular solid layer C on the upper surface of the partition wall 3 slides down on the partition wall 3 as shown in states [III] and [IV] in FIG. Is provided with the guide plate 6 shown in FIG. 2, so that when it slides down, the granular solid body layer advances in the direction in which the guide plate is inclined. That is, the states [II] to [I
V], the granular solid layer 12 moves from the left end to the right end in FIG.

On the other hand, the granular solid layer 13 in the space D
After the space D is located above, the states [II] to [IV] in FIG.
When the same state as the space C is reached, the guide plate 6 comes to the front side from the back side of the sheet of the partition wall 3 in FIG.
The inclination is in the opposite direction. Accordingly, when the granular solid body layer 13 in the space D slides on the partition wall 3 along the guide plate 6, it moves from the right end to the left end in FIG.
That is, in FIG. 1, the granular solid body layer circulates between the left end and the right end of the partition wall 3 as the cylindrical body 2 rotates around the axis 1. Then, at the time of circulation, a part of the heat-treated granular solids fall from the outlet 2B and are taken out as a product.

In this embodiment, as the cylindrical body 2 rotates around the axis 1, the powdery and granular solid layers 12 and 13 in the spaces C and D are raised by one surface of the partition wall 3 in FIG. And slides down as the surface inclines from a horizontal position. Until the sliding down, the gas ejected from the surface of the partition wall 3 flows through the layer from below the granular solid layers 12 and 13 to make good contact with the granular solid in the layer. become.

<Second Embodiment> In this embodiment, the guide plate 6
5 is different from the first embodiment in FIG. 1 in that it is attached to both sides of the partition wall 3 with inclinations that are opposite to each other when viewed from one side perpendicular to the paper surface as shown in FIG. Other configurations are the same as those in FIG. The partition wall 3
No matter which surface of the partition wall faces upward, the guide plates 6 on both sides are inclined in the same direction, so that the granular solids always advance. And outlet 2B
Is discharged from The mounting condition of the guide plate is shown in FIG.
Is shown in a perspective view.

Thus, in this embodiment, the granular solids fed from the inlet 2A come into good contact with the gas from the blast holes 5 provided in the partition wall 3 before reaching the outlet 2B. After receiving the heat treatment, it is taken out as a product from the outlet 2B.

<Third Embodiment> In the first and second embodiments described above, the interior of the partition wall 3 communicates with the blast holes on both sides in one space, but in this embodiment, as shown in FIG. It is characterized in that a separating plate 14 parallel to both surfaces is provided inside, and two independent spaces are formed on each surface side. According to this embodiment, when one surface is positioned upward, the granular solid forms a layer on the one surface, and at this time, the blast holes 5 are closed by the granular material. Even if the gas escapes, the gas escapes to the fumarole on the other surface, and the flare 5
Thus, it is possible to supply a sufficient amount of gas to the above-described one side of the fumaroles without being affected by the difficulty of the fumes. Further, in this embodiment, the inside of the air supply pipe 4 is separated from the above two spaces and provided with a partition 4A by a plane including an axis so as to communicate with each other, thereby forming two air supply systems. If the valve is opened and closed so that air is supplied only to the side space, the capacity of the gas supply source can be reduced by half.

<Fourth Embodiment> In the first to third embodiments, the inside of the tubular body is divided into two spaces by one partition wall, but in the present embodiment, a plurality of partition walls are used. The feature is that it is divided into three or more spaces.

FIG. 8 is a cross-sectional view of the cylindrical body 2 taken along a plane perpendicular to the axis.
This is an example of a case where the image is divided into four by the following. The inside of the partition wall 3 communicates with each other as a gas passage space, and gas is blown out into the internal space of the tubular body 2 from blast holes (not shown) formed on each surface of the partition wall. The shape, number, and angle of the guide plates 6 provided on each surface of the partition wall 3 are appropriately set in accordance with the use conditions. For example, the direction of inclination is such that the powdery and solid mass layer in the partitioned space is inclined from a horizontal position. It is determined by the direction you want to move when sliding down. In the case of FIG. 8, if the inclination direction is the same at the time when the cylindrical body rotates and comes to the same position (for example, the position of 6) in the four partitioned spaces, the powder-grained solid layer is Advance in the same direction about the axis in space. For example, if only one section space is disposed so as to be opposite to the direction of inclination of the guide plate in the other section space, the granular solid layer in the section space is opposite to the other three section spaces with respect to the axis. Move forward in the direction.

FIG. 9 shows an example in which the inside of a plurality of cross-shaped partition walls is separated by a separation plate 14 corresponding to each surface, and gas is independently applied to each surface of the partition wall by another separation plate 15. It is a configuration that can be sent. At that time, in order to efficiently carry out the contact between the powdery and massive solid layer present in each sectioned space and the supplied gas, the phase is separately shifted to each part of the partition wall as described in the third embodiment, and the period is changed. It is also possible to send the gas in a targeted manner.

<Fifth Embodiment> In the above-described first to fourth embodiments, an example is shown in which a flat partition wall is used. However, the partition wall is not necessarily limited to a flat partition wall, but may be a cylindrical partition wall. As long as it forms a surface extending in the axial direction, it may be cylindrical as shown in FIG.

And circulates between both ends of the partition wall 3 in FIG. A portion of the granular solid layer enters cylindrical partition 16 at the right end of the partition assembly of FIG.
It is discharged from the left end of the cylindrical partition wall 16 by the action of the flat partition wall 17 and the guide plates 18 and 18 ′ which are arranged obliquely with respect to the axis. The partition wall 3 in FIG. 10 is a case where the inside is a single gas passage space, but is not necessarily limited to this. For example, as shown in FIG. It is also possible to periodically introduce gas into the blast holes 5 on both sides of the 3 by shifting the phase.

FIG. 11 is a sectional view taken on a plane perpendicular to the axis of the present embodiment in which the partition wall assembly shown in FIG. 10 is installed inside the cylindrical body 2, and has a flat plate shape in which the inside is a gas passage. This is an example of the case where the partition wall 3 is located in parallel with the flat partition wall 17 installed in the cylindrical partition wall 16. The position of the flat partition wall 17 is not necessarily limited to that shown in FIG. 11, and may be provided on a surface orthogonal to the partition wall 3 as shown in FIG. No problem.

<Sixth Embodiment> The partition wall assembly of the previous embodiment shown in FIG. 10 has a structure in which a solid layer of granular material is formed along the axis between both ends of the cylindrical body inside the cylindrical body 2. It is for contacting with the gas ejected from the fumarole or fumarole plate during circulation and sending out a part of the tubular body from near one end to the other end, but is not necessarily limited thereto, for example, in the sixth embodiment. As shown in FIG. 13, a part of the circulating granular solid layer is advanced in one direction in the cylindrical body 2 to form an extruded flow, and is retained for a time necessary for physical change or completion of a chemical reaction. Thereafter, it can be discharged from the other end through the inside of the cylindrical partition plate 16 provided in the cylindrical body 2.

Referring to FIG. 13, the cylindrical body 2 is rotatably supported by a bearing (not shown) around an axis 1 in the figure. The cylindrical body 2 extends along the axis 1 and has two front and rear partition walls 3 and 1 positioned parallel to the paper surface.
9 form a plurality of internal spaces at the front and rear. At this time, the partition walls 3 and 19 are arranged at intervals in the axial direction as shown in FIG. If necessary, the partition wall 3 and a part of the partition wall 19 may be connected. Guide plates 6 are provided on both sides of one partition wall 3,
The inclination directions of the guide plates on both sides are the same on both sides when viewed from one side perpendicular to the paper surface, for example, as shown in FIG. A guide plate 20 is provided on one surface of the other partition wall 19,
The shape, number, and angle are arbitrary, and do not necessarily need to be the same as the guide plates 6 provided on both surfaces of the partition wall 3. A guide plate 20 'is provided on the other surface of the partition wall 19, and its inclination and the like are similar to those shown in FIG. However, as shown in FIG. 10, when viewed from a position perpendicular to the plane of the drawing, the directions of the inclination of 20 and 20 ′ are reversed.

A cylindrical partition wall 16 is provided in the cylindrical body 2, and a flat partition wall 17 is provided therein. Guide plates 18, 18 'are provided on both sides of the partition wall 17, and the shape, number, and angle are arbitrary. However, the inclination directions of 18 and 18 'are reversed when viewed from a position perpendicular to the paper surface as shown in FIG.

In the apparatus of this embodiment, the raw material and the like are supplied from the inlet 22 provided in the member 21 fixed to the space through the axis 1.
Inlet 2 provided at one end of a cylindrical body rotating around
A is sent into the internal space of the cylindrical body 2 through A. Partition wall 3
The solid-grained solid layer inside the cylindrical body divided by the cylinder forms a circulating flow between both ends of the partition wall 3 along the axis along with the rotation of the cylindrical body 2 around the axis 1, so that Entrance 2
The raw materials and the like sent from A are mixed and dispersed in the circulating powdery and granular solid layer.

In the space between the partition wall 3 and the partition wall 19, most of the powdery and granular solid layer 23 rotates the cylindrical body 2 around the axis 1 (in the example of FIG. 13, the clock is viewed from the left end side). With the rotation of the cylindrical body 2, the partition wall 3 and the guide plate 6 circulate so as to return in the direction of the feed port 2 </ b> A for the raw material or the like. By the action of the partition wall 19 and the guide plates 20 and 20 ′, the tubular body 2 advances toward the right end and reaches the space 24 inside the right end. Further, as the cylindrical body 2 rotates, the cylindrical body 2 enters the inside of the cylindrical partition plate 16, and by the action of the flat partition wall 17 and the guide plates 18, 18 ′ disposed on both sides thereof, the cylindrical partition plate 1.
6 flows back in the direction of the left end, and is discharged outside through the outlet 25 of the cylindrical partition plate 16.

Although not shown in FIG. 13, the fumarole or fumarole is provided on one or both of the partition wall 3 and the partition wall 19 on a part or entire surface thereof, and is required for physical change or chemical reaction. Gas is ejected into the granular solid layer.

The structure of the partition wall assembly in the case of FIG. 13 is not limited to the case where the annular space between the cylindrical body 2 and the cylindrical partition wall 16 is divided into two as shown in FIGS.
For example, as shown in FIG. 14, the space between the cylindrical body 2 and the cylindrical partition wall 16 may be divided into a plurality of sections by using a plurality of flat partition walls 3. At this time, a plurality of bleed holes 5 or bleed plates are provided on a part or entire surface of the partition wall 3, and gas is blown out from a gas passage space in the partition wall 3 to form a granular solid mass layer in the partitioned space. Inside can be distributed.

Although the inside of the partition wall 3 in FIG. 14 is a single gas passage space, it is not necessarily limited to this.
For example, as shown in FIG. 15, a separation plate 14 is provided inside the partition wall 3, and the gas to be sent to the blowing holes or the blowing plate provided on both sides of the partition wall 3 is separately fed into each partition space in the partition wall 3. On the other hand, the gas can be periodically supplied with the phase shifted.

<Seventh Embodiment> In the third embodiment shown in FIG. 7, a separating plate is provided inside the partition wall, and the inner space of the partition wall is divided into two partition spaces on one side and the other side. age,
When one surface is directed upward and the other surface is directed downward, the fumes from the fume holes on the one surface are not weakened, but in this embodiment, the separation plate is movable. have.

As shown in FIG. 16 (the guide plate is omitted), the partition wall 3 in this embodiment has a plurality of guide columns 30 extending in the thickness direction of the partition wall 3 at appropriate places. Is provided. A separating plate 31 parallel to the partition wall 3 is provided on the guide column 30 so as to be vertically guided and fall by its own weight. The separation plate 31 preferably covers the area where the plurality of blast holes 5 are provided. However, the separation plate 31 does not necessarily need to be formed as a single sheet, and the area is appropriately divided into a plurality of areas. It is good also as plural sheets so that it may cover. In the present embodiment, the guide pillar is not essential.

When the partition wall 3 of this embodiment rotates with the rotation of the cylindrical body, the separating plate 31 is moved by the partition wall 3.
Is rotated by 180 ° and guided by the guide column 30 to drop. Therefore, the bleed holes 5 on one surface located above are opened, and the bleed holes 5 on the other surface located below are opened.
Is closed. As a result, the pressure of the gas acts only on the fumarole 5 on one side, and the fumarole flows effectively into the powdery solid mass layer on one side without weakening. According to this embodiment, the peripheral device is simplified because the switching valve is not used to apply the gas pressure only to the blast holes on one surface, and the inside of the partition wall does not need to be partitioned into two spaces. For this reason, the thickness of the movable separation plate 31 may be made thicker than that of the apparatus shown in FIG.
In addition, when the movable separation plate 31 falls, it applies an impact force to the lower surface of the partition wall or presses the gas, so that the powdery solid mass adhering to the fumarole is dropped, thereby preventing clogging. There is also the advantage that it can be done.

Next, as shown in FIG.
If the groove portions 32 are formed on both surfaces of the partition wall 1, it is possible to prevent the separation plate 31 from being in close contact with the inner surface of the partition wall and difficult to move when dropping.

[0043]

As described above, in the present invention, the inside is a gas passage space, and a fumarole or fumarole is provided on a part or entire surface thereof, and a guide plate inclined with respect to the axis is provided. Since it is arranged, it is possible to realize a circulating flow or an extruding flow in a granular solid layer presenting a large filling rate in a cylindrical body in accordance with the treatment of the raw material or the like so as to meet the optimum conditions. In addition, gas required for physical changes of raw materials and the like or chemical reaction can be sent to the required place of the granular solid body layer and circulated through it, so that physical change due to heating of the granular solid body or Since the time required for terminating the chemical reaction is reduced, and the granular solid particles can be moved in an extruded flow state, the heat treatment can be performed in a substantially short time.
