[0001]

BACKGROUND OF THE INVENTION The present invention relates to heat treatment of industrial raw materials, intermediate raw materials or wastes (hereinafter referred to as raw materials) in the form of powdery or granular solids or slurries, filter cakes, and viscous liquids. By giving suitable temperature, atmosphere, and residence time to the processing conditions, and by introducing and dispersing the gas required for processing into the raw materials, etc., physical and chemical changes can be achieved with high efficiency and efficiency, and environmental pollution can be achieved. Solid that is suitable for stable operation for a long time with high thermal efficiency without causing
The present invention relates to a horizontal rotary heating device for heat-treating a liquid and a substance that is a mixture thereof.

[0002]

2. Description of the Related Art In the process industry that economically supplies substances useful to society by utilizing physical, chemical, or biological changes, the raw materials are powdery or granular at room temperature,
Some generate large amounts of filter cake, slurry, or viscous liquid substances. As a conventional technique for heating such a substance to cause a physical / chemical change to obtain a useful intermediate material or product, there is a horizontal rotary furnace that performs indirect heating. As an example, a device 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 by bearings 3'at both ends, and has a center slightly inclined with respect to the horizontal. It is designed to rotate about axis 2 '. The raw material or the like to be heated is fed into the vicinity of the 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 toward the lower side of the rotary cylinder. It becomes layered and rolls along with the rotation of the rotary cylinder 1 ′, and gradually moves slowly toward the other end on the low position side.

The rotary cylinder 1'is generally surrounded by a concentric non-rotating outer cylinder 6 ', and a high temperature combustion gas is introduced from an inlet 5'provided on the lower position side to form the rotary cylinder 1'.
Through an annular flow path 7'formed between the outer cylinder 6'and
The gas is exhausted from the exhaust port 8'provided on the high position side. The combustion gas heats the rotary cylinder 1'while flowing through the flow path 7 '. The thermal energy transferred to the rotary cylinder 1'heats the raw material and the like rolling at the bottom thereof to the required temperature. The vapor or gas body in the rotary cylinder 1'generated by the heating is guided to the next step from the outlet 10 'through the opening 9'provided at the high position side end of the rotary cylinder 1'. On the other hand, the solid that has become powdery and has lost the components that evaporate and vaporize due to heating is accompanied by the rotation of the rotary cylinder 1 ′ from the lower end of the rotary cylinder 1 ′ through the hood 11 ′ and the powder and granular material discharge port 12 To'fall.

[0005]

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

(A) <Fusion of feed material> Many of the above-mentioned materials and the like become liquid during heating and heating, and while moving toward the downstream in the rotary cylinder as shown in FIG. In that temperature range, the inner surface of the rotating cylinder is fused and a trouble that hinders stable operation is likely to occur. In addition, in slurry form
If a viscous liquid raw material is supplied as it is, the same problem will occur.To address this, the powdered and granular substances that have been treated are mixed in advance and then fed into the rotary cylinder. However, there is a problem that it is easy to fuse due to slow progress.

(B) <Leakage of Generated Steam / Gas> It is necessary to seal the rotating rotating cylinder at both ends in order to prevent leakage of the steam or gas inside, but the material of the rotating cylinder 1 '. Generally has a large thermal expansion. For example, if the end of the rotary cylinder 1'on the high position side is fixed in the axial direction, the end of the rotary cylinder 1'on the low position side thermally expands during heating. Due to the large axial displacement, it is difficult to achieve a perfect seal with the hood 11 '. This becomes a problem especially when the generated steam / gas contains harmful components. Moreover, since both ends of the rotary cylinder are connected to the line of the next process by separate pipes, the rotary cylinder 1'is not operated by mistake.
It is possible to draw in ambient air from the incompletely sealed point at the lower end of the, which is dangerous as it immediately leads to an explosion.

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

(D) <Small filling rate> The rotary cylinder 1'of FIG. 18 rolls around the central axis which is slightly inclined with respect to the horizontal to roll the layer of the granular material to advance downward, The ratio of the volume of the granular material layer to the volume of the rotating cylinder, that is, the occupation ratio is about 10 to 15%, which is considerably small. It is possible to increase the occupancy rate of powder particles in the rotary cylinder space by creating a weir at the outlet of the rotary cylinder and reducing the inclination angle of the central axis, but the rotation of the rotary cylinder causes the rotation of the powder layer. Only the powder and granular material near the surface in contact with the cylinder and the surface of the powder and granular layer becomes insufficient, and the mixing and heating of the powder and granular material near the center of the powder and granular layer become insufficient.

The present invention solves the problems associated with such conventional devices and has a high filling rate when indirectly heating raw materials and the like, and is a 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 which is inexpensive to construct.

[0011]

According to the present invention, the above object is to provide a rotatable cylindrical body having a substantially horizontal axis of rotation and an opening at least at one end in the axial direction, and the inside of the cylindrical body. A heat treatment is provided, which has a partition wall that divides the space into a plurality of sections and that is substantially parallel to the axis line, and a plurality of guide plates that are attached to the partition wall so as to be arranged in the axial direction inclined with respect to the axis line. In a horizontal rotary heating device in which a substance to be powdered, agglomerated solids is fed from the opening and taken out after heat treatment, part or all of the interior of the partition wall is used as a gas passage space, and the partition wall surface Gas fumaroles or fumaroles are provided on a part of the surface or the entire surface, and the gas required for physical change or chemical reaction of the powdery agglomerate solids in the powdery agglomerate solid layer contacting the surface is supplied from the fumaroles. Achieved by enabling fumes .

[0012]

[Function] The material to be heat-treated, that is, the granular solid is supplied into the cylindrical body from the inlet, but the cylindrical body is rotating around the axis, and during the rotation, the granular solid is It is lifted by one side of the partition wall and then falls.
At that time, the solid particles are slid off while being guided by the guide plate. Therefore, the guide plate advances toward the inclination direction of the guide plate while sliding down from the upper end to the lower end. Since the layer of the powdered and granular solid in the tubular body is in contact with the surface of the partition wall from being lifted to one side by the one surface of the partition wall until it slides down, a plurality of layers provided on that surface are provided. The gas ejected from the fumaroles or the fumarolic plate flows through the powder / agglomerate solid layer and diffuses to the surface of each particle. As a result, a physical change or chemical reaction between the powdery or granular solid and the gas rapidly progresses, and the time required for the heat treatment is significantly shortened.

[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 by a bearing (not shown) around an axis 1. The cylindrical body 2 has at one end an inlet 2A for a powdery or granular solid as a raw material to be subjected to heat treatment, and at the other end an outlet 2B. The tubular body 2 extends along the axis 1 and has a plurality of internal spaces by a hollow partition wall 3 positioned in parallel with the plane of the drawing at the rotational position shown in the drawing, and two partitions by one partition wall 3 in the illustrated case. 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 and supplies gas into the hollow space of the partition wall 3. The gas is jetted into the inside of the tubular body 2 through a plurality of jet holes 5 provided on a part or the entire surface of the partition wall 3. A plurality of guide plates 6 are arranged on both surfaces of the partition wall 3 while being inclined in the same direction in FIG. The shape, number and angle of the guide plates 6 are appropriately determined according to the heat treatment conditions.

FIG. 2 is a partially cutaway perspective view for explaining the partition wall 3 and the guide plate 6 of FIG. 1, and the arrow 7 indicates the direction in which gas is fed. The introduced gas passes through the space inside the partition wall 3 and is ejected from the plurality of fumaroles 5.

The fumaroles 5 provided on a part or the entire surface of the partition wall are not limited to those shown in FIGS. 1 and 2, but may be, for example, equilateral triangular fumaroles, or the fumaroles 5. The shape itself can be various shapes, and for example, it may be a slit shape. Also, instead of the fumarole, Fig. 3
The partition wall is formed by two plates 8 and 10, an opening 9 is formed in the inner plate 8, a wire net or a porous plate 11 is attached, and the above-mentioned wire net or the porous plate 11 is attached. Alternatively, as shown in FIG. 3, the outer plate 10 having a plurality of fumaroles 5 may be stacked. In that case, the outer plate 1
0 may be omitted.

FIG. 4 is an explanatory view showing the manner of movement of the powdery, granular, and lumpy solids in the rotary heating apparatus of FIG.

Considering the case where the cylindrical body 2 is rotating clockwise when viewed from the left end side in FIG. 1, the powder-granular solid material formed in the cylindrical body 2 in FIG. The layer state is as shown in state [I] of FIG. In addition, in FIG.
C and D indicate two cylindrical inner spaces divided by the partition wall 3, and 12 and 13 indicate powder-granular solid layers existing in the spaces C and D, respectively.

When rotated 90 degrees from the state [I] in FIG. 4, the state becomes the state [II], and the gas ejected from the inside of the partition wall 3 through the fumaroles 5 is in the solid granular layer 12 in the space C. The solid and gas in the layer effectively contact with each other. When further rotated by about 45 degrees or more, the powder / agglomerate solid layer C on the upper surface of the partition wall 3 slides down on the partition wall 3 as in the states [III] and [IV] of FIG. Since the guide plate 6 shown in FIG. 2 is disposed in the sheet, the solid layer of powder and granules advances in the inclined direction of the guide plate when sliding down. That is, the above states [II] to [I
Due to the rotation toward V], the granular solid material layer 12 moves from the left end to the right end in FIG.

On the other hand, the solid powder layer 13 in the space D is
State [II] to [IV] in FIG. 4 after the space D is located above
In the same state as the space C, the guide plate 6 comes to come to the front side from the back side of the partition wall 3 in FIG.
The slope is in the opposite direction. Therefore, when the powder / agglomerate solid 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 powder / agglomerate solid layer circulates between the left end and the right end of the partition wall 3 as the cylindrical body 2 rotates about the axis 1. Then, during the circulation, a part of the heat-treated powdery or granular lump solid falls from the outlet 2B and is 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 moved upward by one surface of the partition wall 3 in FIG. And is slid off as the surface inclines from a horizontal position. Before the sliding down, the gas ejected from the surface of the partition wall 3 flows through the layer from below the granular solids layers 12 and 13 to make good contact with the granular solids in the layer. become.

<Second Embodiment> In this embodiment, the guide plate 6 is used.
1 is different from the first embodiment in FIG. 1 in that it is mounted on 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. Partition wall 3 above
The guide plates 6 on both sides of the partition wall both have an inclination in the same direction regardless of which surface of the partition wall is facing upward, so that the solid powder or granular solid always advances. And outlet 2B
Emitted from. The installation status of the guide plate is shown in Fig. 6.
In perspective view.

Thus, in the present embodiment, the powdery or granular solids charged from the charging port 2A are in good contact with the gas from the fumaroles 5 provided in the partition wall 3 before reaching the discharging port 2B. After undergoing the heat treatment, it is taken out as a product from the take-out port 2B.

<Third Embodiment> In the first and second embodiments described above, the interior of the partition wall 3 communicates with the fumaroles on both sides in one space, but in this embodiment, as shown in FIG. It is characterized in that the separation plates 14 parallel to the both surfaces are provided inside, and two independent spaces are formed on the side of each surface. According to the present embodiment, when one surface is positioned upward, a layer of the solid particles is formed on the one surface. At that time, the fumarole 5 is closed by the solid particles. Even if it peels off, the gas escapes to the fumaroles on the other surface, and the fumaroles on the one surface 5
It is possible to supply a sufficient amount of gas to the fumaroles on the one surface without being affected by the fact that it becomes difficult for fumes to blow. Further, in this embodiment, the inside of the air supply pipe 4 is provided with a partition 4A by a surface including an axis so as to separate and communicate with the above two spaces, thereby forming two air supply systems and If the valve is opened and closed so that air is supplied only to the space on the side, the capacity of the gas supply source is reduced to half.

<Fourth Embodiment> In the first to third embodiments, the inside of the cylindrical body is divided into two spaces by one partition wall, but in this 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, and the inner space of the cylindrical body 2 is divided into cross-shaped partition walls 3.
This is an example of dividing into four by. The inside of the partition wall 3 communicates with each other as a gas passage space, and the gas is ejected into the inner space of the tubular body 2 from the fumaroles (not shown) formed on each surface of the partition wall. The shape, number, and angle of the guide plates 6 arranged on each surface of the partition wall 3 are appropriately set according to usage conditions. For example, the inclination direction of the guide plates 6 is inclined from the horizontal position of the solid granular layer in the divided space. And it depends on the direction you want to move when you slide down. In the case of FIG. 8, if the guide plates in the four divided spaces have the same inclination direction when the tubular body comes to the same position by rotation (for example, the position of 6), the powdery-agglomerate solid layer is divided into the respective divided regions. Advance in the same direction about the axis in space. For example, if only one section space is arranged so as to be opposite to the inclination direction of the guide plate of the other section spaces, the granular solid lump solid layer in that 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 separating plate 14 corresponding to each surface, and a gas is independently supplied to each surface of the partition wall by another separating plate 15. It is a structure that can be sent. At that time, in order to efficiently carry out the contact between the powdered and granular lump solid layer existing in each divided space and the feed gas, the phase is separately shifted to each part of the partition wall as described in the third embodiment, and the cycle is changed. It is also possible to introduce a gas.

<Fifth Embodiment> In the above-described first to fourth embodiments, an example in which a flat plate-shaped partition wall is used has been shown, but the partition wall is not necessarily a flat plate-shaped partition wall, and is a tubular body. As long as it has a surface extending in the axial direction, it may be cylindrical as shown in FIG. FIG. 10 shows a space as a gas passage inside, a flat partition wall 3 having jet holes 5 on a part or the whole surface thereof, a cylindrical partition wall 16 substantially parallel to the axis 1, and the cylinder. The example of the partition wall assembly comprised by the flat plate-shaped partition wall 17 installed inside the partition wall 16 is shown. Arrow 7 indicates the gas feeding direction,

When the apparatus of this embodiment having such a partition wall assembly installed therein is rotated clockwise as viewed from the left end side of FIG. 10, the powder / agglomerate solid layers in the partition spaces on both sides of the partition wall 3 are rotated. And circulates between both ends of the partition wall 3 in FIG. A portion of the solid agglomerated solid layer enters the cylindrical partition wall 16 at the right end of the partition wall 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 ′ that are arranged to be inclined with respect to the axis. The partition wall 3 in FIG. 10 is a case where the inside is one gas passage space, but the present invention is not necessarily limited to this. For example, the gas passage space is divided by the separation plate 14 as shown in FIG. It is also possible to periodically inject gas by shifting the phases to the gas ejection holes 5 on both sides of 3.

FIG. 11 is a cross-sectional view of the partition wall assembly shown in FIG. 10 in a plane perpendicular to the axis of the apparatus of this embodiment in which the partition wall assembly is installed inside the cylindrical body 2. The inside is a gas passage. In this example, the partition wall 3 and the flat partition wall 17 installed in the cylindrical partition wall 16 are located in parallel with each other. 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. 12, or at an intermediate angle. It doesn't matter.

<Sixth Embodiment> In the partition wall assembly of the previous embodiment shown in FIG. 10, inside the tubular body 2, a powder / agglomerate solid layer is provided along the axis between both ends of the tubular body. It is for contacting the gas ejected from the fumarole or the fumarolic plate during circulation and sending a part of it from the vicinity of one end of the tubular body to the other end, but it is not necessarily limited to this, for example, as a sixth embodiment. As shown in FIG. 13, a part of the circulated powder / agglomerate solid layer is advanced in one direction in the cylindrical body 2 to form an extruded flow, which is retained for a time necessary for the physical change or the end of the chemical reaction, After that, it can also be discharged from the other end through the inside of the cylindrical partition plate 16 provided in the cylindrical body 2.

The device of FIG. 13 will be described in detail. In the drawing, a cylindrical body 2 is rotatably supported by a bearing (not shown) around an axis line 1. The tubular body 2 extends along an axis 1 and is provided with two front and rear partition walls 3 and 1 positioned parallel to the paper surface.
9 forms a plurality of internal spaces in the front part and the rear part. At that time, the partition walls 3 and 19 are installed 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 to each other. 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 as shown in FIG. 2, for example. A guide plate 20 is provided on one surface of the other partition wall 19,
The shape, number, and angle are arbitrary, and they are not necessarily the same as the guide plates 6 arranged on both sides of the partition wall 3. A guide plate 20 'is provided on the other surface of the partition wall 19, and the state of inclination and the like is similar to that shown in FIG. However, as shown in FIG. 10, 20 and 20 'have opposite inclination directions when viewed from the direction perpendicular to the paper surface.

A cylindrical partition wall 16 is provided in the cylindrical body 2, and a flat plate partition wall 17 is installed inside the cylindrical partition wall 16. Guide plates 18 and 18 'are provided on both sides of the partition wall 17, and the shape, number and angle thereof are arbitrary. However, as shown in FIG. 10, 18 and 18 'have opposite inclination directions when viewed from a position perpendicular to the paper surface.

In the apparatus according to the present embodiment, the axis 1 is fed from the charging port 22 provided in the member 21 for fixing the raw material and the like in the space.
Inlet 2 provided at one end of a cylindrical body that rotates around
It is fed into the inner space of the tubular body 2 through A. Partition wall 3
The powdery-agglomerate solid layer inside the tubular body divided by the above forms a circulating flow between both ends of the partition wall 3 along the axis along with the rotation of the tubular body 2 around the axis 1, so Entrance 2
The raw materials and the like fed from A are mixed and dispersed in the circulating powdery, granular, and lump-like solid layer.

In the space between the partition wall 3 and the partition wall 19, most of the powder / agglomerate solid layer 23 is the rotation of the cylindrical body 2 around the axis 1 (in the example of FIG. Along with the rotation), the partition wall 3 and the guide plate 6 act to circulate and move back in the direction of the feed port 2A for the raw material and 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 in the right end. Further, as the tubular body 2 rotates, it enters the inside of the cylindrical partition plate 16, and by the action of the flat partition wall 17 and the guide plates 18 and 18 ′ arranged on both sides thereof, the cylindrical partition plate 1
It flows through the inside of 6 so as to return to the left end, and is discharged to the outside from the outlet 25 of the cylindrical partition plate 16.

Although not shown in FIG. 13, the fumaroles or fumaroles are provided on some or all of the surfaces of one or both of the partition wall 3 and the partition wall 19 and are necessary for physical changes or chemical reactions. The gas is ejected into the solid layer of powder and granules.

The structure of the partition wall assembly in the case of FIG. 13 is not necessarily 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, a plurality of flat partition walls 3 may be used to divide the space between the tubular body 2 and the cylindrical partition wall 16 into a plurality of spaces. At this time, a plurality of fumaroles 5 or fumarolic plates are provided on a partial surface or the entire surface of the partition wall 3 to eject a gas from the gas passage space in the partition wall 3 to form a solid layer of powder and granules in the partitioned space. It can be distributed inside.

The inside of the partition wall 3 in FIG. 14 is one gas passage space, but 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 fumaroles or fumaroles provided on both sides of the partition wall 3 is separately fed to each partition space in the partition wall 3. On the other hand, the gas can be sent in periodically by shifting the phase.

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

As shown in FIG. 16 (a guide plate is omitted), the partition wall 3 in this embodiment has a plurality of guide pillars 30 extending in the thickness direction of the partition wall 3 at appropriate places therein. It is provided. A separating plate 31 parallel to the partition wall 3 is vertically guided on the guide column 30 and is provided so as to be dropped by its own weight. Although the separating plate 31 preferably covers the region where the plurality of fumaroles 5 are provided, it does not necessarily have to be formed of one sheet, and the region is appropriately divided into a plurality of regions. It may be a plurality of sheets so as to cover. In this embodiment, the guide pillar is not essential.

When the partition wall 3 of this embodiment is rotated with the rotation of the cylindrical body, the separating plate 31 is moved to the partition wall 3
Is rotated by 180 ° and is guided and dropped by the guide column 30. Therefore, the fumarole 5 on one surface located above is opened, and the fumarole 5 on the other surface located below is open.
Is closed. As a result, the pressure of the gas acts only on the fumaroles 5 on one surface, and the fumes effectively flow into the powder / agglomerate solid layer on one surface without weakening. According to this embodiment, since the switching valve is not used to apply the gas pressure only to the fumaroles on one surface, the peripheral device is simplified and the interior of the partition wall is not divided into two spaces. Since it is good, the partition wall can be made compact as a whole as compared with the device shown in FIG.
Further, when the movable separating plate 31 falls, an impact force is applied to the lower surface of the partition wall, or the gas is pressed, so that the solid particles that have adhered to the fumaroles are dropped and clogging is prevented. There is also an advantage that it can be done.

Next, as shown in FIG. 17, the movable separating plate 3
If the groove portions 32 are formed on both surfaces of No. 1, when the separating plate 31 is dropped and moved, it does not come into close contact with the inner surface of the partition wall and it is difficult to move.

As described above, in the present invention, the inside is the gas passage space, and the fumarole or the fumarolic plate is provided on a part or the whole surface thereof, and the guide plate inclined with respect to the axis is provided. Since they are arranged, it is possible to realize a circulating flow or an extruding flow in the cylindrical solid body having a large filling rate in the cylindrical body depending on the treatment of the raw material or the like so as to meet the optimum conditions. Furthermore, since the gas required for physical change or chemical reaction of the raw material or the like can be fed into a necessary place of the powdery or granular solid layer and circulated therein, physical change by heating the powdery or granular solid or Since the time required for ending the chemical reaction is shortened and the solid particles in the form of agglomerates can be moved in an extruding flow state, the heat treatment can be performed in a substantially short time.
