Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention treats industrial intermediate raw materials or wastes that generate flammable or harmful or odorous vapor or gas when heated, and treats them without causing environmental pollution. The present invention relates to a horizontal rotary furnace device for recovering solids, liquids, or a substance that is a mixture thereof, which is suitable for stable operation for a long period of time with high thermal efficiency.

[0002]

2. Description of the Related Art In the process industry that supplies substances useful to society by utilizing physical, chemical or biological changes, powdery solids and high melting point liquids are mixed as intermediate products or wastes. Some exist and generate a large amount of substances in the form of agglomerates, filter cakes, slurries or viscous liquids at room temperature. As a conventional technique for recovering a high-melting point liquid from such a substance to obtain a useful intermediate material or fuel, there is a horizontal rotary furnace device that performs indirect heating. As an example, a device as shown in FIG. 33 is widely used. Such a rotary furnace heats powdery organic substances to a high temperature to cause thermal decomposition and separates useful volatiles and solids, that is, when performing so-called carbonization, or for example, heating a metal sulfate to a high temperature to oxidize metal. It is used to separate sulfur dioxide from gas.

In the apparatus shown in FIG. 33, reference numeral 1'denotes a rotary cylinder made of a heat-resistant metal plate, and 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 to be heated is fed into the vicinity of the high-side end of the rotary cylinder 1 ′ through a raw material inlet 4 ′ provided in the rotary cylinder 1 ′, and then layered downward toward the rotary cylinder. The rotary cylinder 1 ′ rolls with the rotation of the rotary cylinder 1 ′, and gradually moves toward the end on the low position side in sequence.

The rotating 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, and the rotating cylinder 1'is It flows through an annular flow path 7'formed between "and the outer cylinder 6 ', and is exhausted from a discharge 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 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 which has lost the components that evaporate due to heating and is in the form of powder 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 or 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 feedstock> Many of the above-mentioned feedstocks become liquid during heating and heating, and the temperature range thereof is in progress while moving downstream in the rotary cylinder as shown in FIG. As a result, problems are likely to occur when the inner surface of the rotary cylinder is fused and hinders stable operation. If the raw material in the form of a slurry or a viscous liquid is supplied as it is, the same problem will occur. Therefore, the powdered and granular substances after the treatment are mixed in advance and then fed into the rotary cylinder. Since the progress is slow, there is a problem that the fusion is easy. (B) <Leakage of generated steam / gas> It is necessary to seal the rotating rotary cylinder at both ends in order to prevent leakage of internal steam or gas, but the material of the rotary cylinder 1'is generally heat. A large expansion is used. For example, if the high position side end of the rotary cylinder 1'is fixed to the axial direction, the low position side end of the rotary cylinder 1'is largely displaced in the axial direction during heating. However, it is difficult to complete the seal with the hood 11 '. This becomes a problem especially when the generated steam / gas contains harmful components. In addition, since both ends of the rotary cylinder are connected to the line of the next process by separate pipes, there is a possibility that the outside air may be sucked from the incompletely sealed position at the lower end of the rotary cylinder 1 ′ due to an erroneous operation. , Which is dangerous as it will lead to an immediate explosion. (C) <Thick rotary cylinder> Since the rotary cylinder 1'in FIG. 33 is heated by the combustion gas and becomes high in temperature, its strength is significantly reduced. In such a state, it is necessary to make the plate thickness of the rotary cylinder 1 ′ sufficiently large in order to make the structure sufficiently safe against the stress when rolling a heavy material in the rotary cylinder supporting both ends.
Many heat-resistant materials with high cost will be used. (D) <Small filling rate> The rotary cylinder of FIG. 33 moves downward by rolling the layer of the granular material by rotation around the central axis that is slightly inclined with respect to the horizontal. The ratio of the volume to the rotary cylinder volume, that is, the occupation rate 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.

[0006] The present invention solves the problems associated with such conventional devices, and indirectly uses a raw material for mixing powdery solids and a high melting point liquid or a raw material for generating useful or harmful vapor or gas by thermal decomposition. Provides a horizontal rotary furnace device that can be safely and continuously operated without causing environmental pollution when heating and separating them to produce powdered or granular solids as products or residue, and at a low construction cost. The purpose is to do.

[0007]

According to the present invention, the above object is to arrange a tubular body made of a heat insulating / heat transfer material in a rotatable outer cylinder made of a heat insulating material and having an axis extending substantially in the lateral direction. A heating gas flow path is formed by the annular space between the tubular body and the outer tube, and the raw material to be heated is fed from the open end of the tubular body opened at the end of the outer tube. In a device that is put into a tubular body and taken out after heating, the tubular body is supported so that one end in the axial direction is opened and the other end is sealed and that the tubular body rotates integrally with the outer cylinder around a substantially horizontal axis. A partition wall is provided inside the tubular body, the partition wall being substantially parallel to the axis line that divides the internal space of the tubular body into a plurality of parts except for both ends in the axial direction of the tubular body, and both sides of the partition wall with respect to the axis line. The guide plates that incline each other so that the inclinations are substantially the same on both sides. Only the supply pipe for delivery of the raw materials from the the opened end is achieved by provided to enter.

[0008]

In the present invention as described above, the weight of the cylindrical body is supported by the outer cylinder which rotates integrally with the cylindrical body.

When the cylindrical body rotates, in the two spaces partitioned by the guide plates that are inclined in substantially the same direction,
The powder or granular material formed by heating the raw material is rolled by the rotation of the tubular body and is fed by the guide plate in the space inside the tubular body. Of the above two spaces, the granular material in one space that has been positioned on the upper side by the rotation of the cylindrical body moves along the upper surface of the guide plate when moving to the lower side by the further rotation. Slide down, for example,
It is sent from the open end side of the tubular body to the closed end side. Next, when the other space that was originally on the lower side comes to be positioned on the upper side, the guide plate in this other space is inclined opposite to the inclination of the guide plate when the one space is on the upper side. To have. Therefore, the granular material in the other space is sent from the closed end side to the open end side.

Thus, when the granular material supplied from the opening end side into one of the spaces reaches the closed end, it wraps around in the other space in the area without the partition wall and is opened by the action of the guide plate in the other space. Return to the edge. Thus, the granular material is folded back in the region where no partition wall exists at both ends of the tubular body, and circulates in the one space and the other space. During the circulation process, the granular material receives the heat of the heating gas sent into the annular space between the cylindrical body and the outer cylinder from the cylindrical body and is heated.
The heated powder and granules are circulated in the tubular body at least once, and then overflow to be discharged from the open end. The raw material sent from the supply pipe is dispersed and mixed in the high temperature powder and granules existing in the area on the opening end side, and it is heated without solidifying into lumps to generate gas and vapor and become powder and granules. .

[0011]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 32 of the accompanying drawings.

FIG. 1 is a vertical cross-sectional view showing a first embodiment device of the present invention. In FIG. 1, reference numeral 1 denotes a tubular body made of steel or a heat-resistant / heat-transfer material, an opening 2 is formed at one end (left end in the drawing), and the other end (right end in the drawing) is sealed. Reference numeral 3 denotes an outer cylinder composed of a heat-resistant or heat-insulating material and a strong outer plate. The outer cylinder 3 accommodates the cylindrical body 1 therein and supports it. For example, the tubular body 1 is integrally supported by the outer cylinder 3 at the opening 2 at the left end,
At other portions, that is, at appropriate positions in the axial direction, the tubular body 1
Is supported by the outer cylinder 3 via an appropriate member (not shown) that allows displacement due to thermal expansion in the axial direction. Thus, the outer cylinder 3 and the tubular body 1 rotate integrally about the substantially horizontal axis 4. In addition, 5 is a rotating outer cylinder 3
Is a bearing member for supporting.

A high temperature combustion gas generator 6 is disposed adjacent to the right end side of the outer cylinder 3 and is connected to the high temperature combustion gas generator 6.
A has entered into the connection port 3A of the outer cylinder. The non-rotating high-temperature combustion gas generator 6 and the rotating outer cylinder 3 are sealed by a seal 7 that allows relative rotation to prevent leakage of combustion gas and intake of air. In order to prevent the combustion gas from directly hitting the end face of the tubular body 1 and overheating it, in the present embodiment, as a desirable mode, an opening 8A is formed between the end face on the sealed side of the tubular body 1 and the connecting portion 6A. A protective wall 8 made of a heat-resistant material is provided. Further, an exhaust port 9 is provided at the left end portion of the outer cylinder 3, and after the combustion gas has passed through the opening 8A of the protective wall 8, an annular space between the tubular body 1 and the outer cylinder 3 is formed. The flow path 10 is made to flow to the left in the flow path 10 and is led to the next step through the exhaust port 9 and the exhaust pipe 11.

In the opening 2 of the cylindrical body 1, a supply pipe 1 for supplying the granular material as a raw material to be heat-treated into the cylindrical body 1.
2 is installed to enter. The tubular body 1 is provided with a partition wall 13 extending parallel to the axis 4 except for a region where the supply pipe 12 exists at the end on the side of the opening 2 and a region at the other end that is sealed. It is divided into two spaces that are long in the axial direction and can communicate with each other. The partition wall 13
A plurality of guide plates 14 that are inclined on both sides in the substantially same direction with respect to the axis are attached in parallel. The guide plate may be provided over the entire width of the partition wall in the height direction as shown in FIG. 2, or may be partially provided in the same direction as shown in FIG.

A discharge pipe 16 is connected to the opening 2 of the cylindrical body 1 via a seal 15 which allows the cylindrical body 1 to rotate, and the discharge pipe 16 and an exhaust pipe 16A extending upward. It is branched to a powder and granular material outlet 16B extending downward.

In addition, A in FIG. 1 of the cylindrical body 1 and the outer cylinder 3
The cross sections at -A, BB, and CC are shown in FIGS. 4 and 5, respectively.
As in FIG.

In the apparatus of this embodiment, the raw material is heated as follows.

First, before the raw materials are charged, a small amount of powder particles that have already been heated are charged so as to cover the bottom surface of the cylindrical body 1. In this state, the raw material is introduced into the tubular body 1 through the opening 2 of the tubular body 1 by the supply pipe 12 almost continuously.

The granular material rolls in the two spaces divided by the partition wall 13 as the cylindrical body 1 rotates. At that time, the powder or granular material as the raw material in the one space that has come to be positioned on the upper side slides down on the surface of the guide plate 14 when the one space moves to the lower side, and from the opening 2 side. It will be sent toward the closed end side. Then, when the other space that was originally on the lower side becomes the upper side, the guide plate 14 in the other space is
Is the guide plate 14 when the above one space is on the upper side.
The powder and granules are fed from the closed end side toward the opening 2 side when moving downward. Further, since the partition wall 13 is not provided at both ends in the axial direction and the spaces are communicated with each other, the powdery particles circulate in the spaces.

The principle of the operation of feeding the powder particles by the guide plate will be described in detail below.

For the sake of convenience, assuming that the space on the left side in FIG. 7 is A and the space on the right side is B, in FIG. 8 in a state rotated by 90 ° from the state in FIG. 7, the granular material on the A side is layered on the partition wall 13. However, in the stage of FIG. 9 further inclined by 60 °, it slides down along the guide plate 14 by gravity, and in FIG. 10 rotated by 180 °, a layer is formed on the bottom of the tubular body 1. That is, the powder or granular material on the A side moves along the guide plate every time it makes one rotation, from the opening 2 to the other end (back) in FIG.

Similarly, in FIG. 11 further rotated by 90 °, the B-side granular material forms a layer on the partition wall 13, and further advances by 60 °, for example, and slides down along the guide plate 14 as shown in FIG. . At that time, although the B-side guide plate is provided with the same inclination as the A-side guide plate, 360 so as to have an inclination opposite to that of the A-side guide plate at the same position in FIGS. 8 and 9. ° Fig. 13 after rotation is complete
At the time point of, the movement in the opposite direction is performed by substantially the same amount as the A side. That is, in FIG. 1, due to the rotation of the tubular body 1, the powder particles on the A side move in the direction from the opening 2 to the back portion, and the powder particles on the B side move in the direction from the back portion to the opening 2, When the rotation speed is increased, the powdery particles move at a large mass velocity in the inside of the cylindrical body 1 in the direction of the central axis and circulate, and the mass velocity of the circulation can be controlled by the rotation speed.

On the other hand, in FIG. 1, the combustion gas supplied from the combustion gas generator 6 into the outer cylinder 3 is exhausted from the exhaust pipe 11 via the flow path 10, while the cylindrical body 1 is heated,
The powder or granular material circulating in the tubular body 1 is heated.

Thus, in the vicinity of the opening 2 of the tubular body 1, at the bottom of the tubular body 1, a large amount of high-temperature powder particles circulating at a large mass velocity from the direction of the other end are rolling. ,
The continuously charged raw material is immediately introduced into this high-temperature powder and granular material, and circulates toward the other end of the tubular body while being heated and treated. The raw material in the powder or granular material that folds back and circulates at the other end of the tubular body is substantially heated and treated by a sufficiently long residence time and becomes a part of the circulating powder or granular material.
Of the circulating granular material, the amount corresponding to the flow rate of the granular material in the feed material is sufficiently heated during circulation, overflows from the opening, and is discharged to the outside of the cylindrical body 1. Granule outlet 16B
Exhausted through. The vapor or gas body generated by heating the inside of the tubular body 1 is guided to the next step from the exhaust pipe 16A through the opening 2.

In the present embodiment, the space of the cylindrical body is equally divided into two by one partition wall, but the present invention is not limited to this, and as shown in FIGS. It is also possible to shift them, or to change the size and position of the guide plates on both sides of the partition wall, and also to form two system circulation paths.

In the apparatus of the first embodiment shown in FIG. 1, the opening 2 is wide open so that the heated granular material rolling in the tubular body 1 overflows from the opening 2. Although it is configured, when it is required to discharge only the heated and granular material in the vicinity of the opening, the granular material scraping mechanism shown as the second embodiment in FIGS. 17 and 18 is provided. Is preferably used. FIG. 17 is a vertical sectional view showing a second embodiment,
FIG. 18 is a sectional view taken along line DD in FIG.

In FIG. 17, a guide cylinder 20 fixedly provided to the discharge pipe 16 is axially inserted into the opening 2 of the cylindrical body 1, and a powdery / grainy material receiving opening 21 is formed in the upper part thereof. ,
On the other hand, inside the cylindrical body 1, the receiving opening 21 is formed in the axial direction.
A scraping plate 22 for powder particles is provided in the range.
The scraping plate 22 has a side plate 23 for preventing powder particles from spilling.

In the apparatus of this embodiment, the cylindrical body 1
The heated powder or granular material at the bottom is scraped upward by the rotation of, and the powder or granular material receiving opening 21 at the top of the guide cylinder 20 is rotated.
It is dropped into the inside of the guide tube 20 via the. At that time, in order to control the discharge flow rate of the discharged granular material to a predetermined value,
A thin cylinder having a screw 24 as shown in FIG. 19 is preferably provided outside the raw material supply pipe 12 and can be rotated. The raw material supply pipe 12 does not necessarily have to be on the central axis of the tubular body as shown in the above-mentioned embodiment, and if it can be installed in the opening 2 of the tubular body 1,
The position, size and angle are arbitrary.

Further, the tip of the supply pipe 12 may extend beyond the end of the partition wall 13 on the inlet side in the axial direction as shown in FIG. At that time, since the supply pipe 12 is normally non-rotating and the partition wall 12 rotates, when the partition wall 12 includes the central axis 4, for example, as shown in FIG. 21, one side of the partition wall 13 is provided. It is possible to introduce and disperse the raw material only in the high-temperature granular material layer that circulates and moves at a position sufficiently distant from the opening.

When the required physical and chemical changes are not completed unless the raw material stays in the tubular body 1 for a long time, the powder and granules that have undergone these changes are formed in the openings of the tubular body 1. It is necessary to discharge the powder or granules circulating from the end (rear part) on the side opposite to 2 toward the opening 2 without mixing the raw material immediately after being put into the outside of the cylindrical body. . In the third embodiment, by utilizing the rotation of the tubular body, a part of the granular material layer located at a position apart from the opening of the tubular body is taken out substantially continuously and the inside of the tubular body 1 is removed. It is possible to discharge the gas through the opening 2 to the outside of the cylindrical body.

22 is a vertical sectional view showing the third embodiment device, FIG. 23 is a sectional view taken along line FF in FIG. 22, and FIG. 24 is a sectional view taken along line GG in FIG. In FIG. 22,
Reference numeral 30 denotes a flat plate made of steel or a heat-resistant material that extends substantially orthogonally to the partition wall 13 in the axial direction. At the right end of the flat plate 30, the granular material that circulates from the inner wall 13 of the cylindrical body. It forms an open space to welcome in.
As shown in FIG. 22, a guide plate 31 that is inclined with respect to the central axis is provided in the space having a string-shaped cross section, and
The powder particles are moved in the direction of the opening 2 of the tubular body 1 by the same principle as described in FIG. As shown in FIGS. 22 and 23, an opening 32 is provided in the vicinity of the opening 2 of the tubular body 1 in an elongated space having a lunar-shaped cross section separated by the flat plate 30. It is scraped up and dropped into the inside of the guide cylinder 20 through the powder / granule inlet 21 provided in the upper part of the guide cylinder 20. Further, the method of installing the guide plate in the space having a lunar cross section does not necessarily have to be the same as that of the guide plate 14 on the partition wall 13, and the point is that the rotation of the tubular body 1 causes the opening 2 to move. Any material can be used as long as it has a function of sending out the granular material in the direction. A method of quantitatively discharging the powder or granular material that has fallen inside the guide cylinder is arbitrary, but preferably a screw as shown in FIG. 19 can be used. Although FIG. 22 shows the case where the number of the flat plates 30 is one, the number is not necessarily limited to one, and a plurality may be used. The elongated space is not limited to the lunar shape shown in the figure, but may be, for example, an annular shape or a part thereof.

The outside of the cylindrical body 1 in FIG. 1 is a flow path 10 for the high temperature combustion gas, but in order to make the heating of the cylindrical body 1 by the high temperature combustion gas as uniform as possible, a fourth embodiment is used. As shown in FIGS. 25 to 27, a plurality of baffle plates 41 are provided outside the tubular body 1 to make the flow of combustion gas in the flow passage 10 uniform. At this time, the baffle plate 41 can also serve as a support for accommodating the tubular body 1 inside the outer tube 30. FIG. 26 shows H- of FIG.
FIG. 27 is a sectional view taken along line H-I in FIG. 25.

In the above-mentioned embodiments, the tubular body 1 is made of steel or a heat-resistant material. However, when heating at high temperature is required, a refractory material or ceramic having good thermal conductivity is used. The fifth embodiment can be constructed as shown in FIGS. 29 is a sectional view taken along line JJ of FIG. At that time, in order to support the cylindrical body 1 in the outer cylinder 3, as shown in FIG. 30, a plurality of high temperature combustion gas passages 10 can be constituted by the heat resistant material 51.

Further, although the high temperature combustion gas generator 6 is fixed in the first and fifth embodiments, it is not necessarily limited to this, and the high temperature combustion gas generator 6 is not necessarily limited to that, but the central axis as in the sixth embodiment shown in FIG. It can be directly connected to the outer cylinder 3 which rotates around 4. In FIG. 31, reference numeral 61 denotes a fuel inlet, which burns in the high temperature combustion gas generator 6 by the air sent from the air inlet 62. At this time, air can be fed in from another air inlet 63 in order to bring the temperature of the high temperature combustion gas to a predetermined value. Incidentally, 64 is a seal for sealing the rotating part.

Next, a seventh embodiment of the present invention will be described.

Partition wall 1 as in the first and fifth embodiment devices
The cylindrical body 1 on which the 3 and the guide plate 14 are installed circulates the internal granular material in the left-right direction along the central axis at a large mass velocity by the rotation around the central axis 4, so that the high temperature combustion gas flows. Even if the tubular body 1 is heated while flowing in the passage 10,
Since it is possible to keep substantially all of the powder and granules inside the tubular body 1 at a predetermined temperature, local heating of the powder and granules is unlikely to occur and uniform heating is performed. Therefore, the temperature difference between the high temperature combustion gas for heating and the tubular body 1 can be increased, and therefore the surface area of the tubular body required for heat transfer can be designed to be small. At that time, the temperature of the combustion gas discharged from the combustion gas discharge port 11 in the outer cylinder 3 to the outside of the apparatus becomes high and a large amount of thermal energy is retained, so that the seventh embodiment is denoted by reference numeral 71 in FIG. Energy is recovered using a different heat exchange device, the combustion air fed from the inlet 72 is heated, and the air inlet pipe 7 is passed through the outlet 73.
It can be fed into the hot combustion gas generator 6 from 4 and 75.

The steam or gas produced by heating the inside of the tubular body 1 enters the vapor separation column 76 through the exhaust pipe 16A of FIG. 32, and is preferably taken out from the outlet 77 as a liquid. When a harmful gas such as sulfurous acid gas exists in the gas body that cannot be liquefied and separated in the vapor separation tower 76, the gas body is sent to the harmful gas separation device 78 to be separated, Can be combusted with fuel through conduit 79 via inlet tube 80. At that time, it is not always necessary to mix with the fuel, and the fuel may be fed into the high temperature combustion gas generator 6 by using a feed pipe separate from the feed pipe 80.

The combustion gas discharged from the heat exchanger 71 has a low temperature and is discharged to the outside of the system via the conduit 81.

The invention is not limited to the embodiments shown, but may vary within the scope of the claims. For example,
The geometric center and the rotation center of the cylindrical body can be decentered. By doing so, the stirring force of the granular material is increased,
Adhesion to the wall surface is more reliably prevented. At that time,
It is necessary that the opening for supplying the powder or granular material is provided at the center of rotation, and the outer peripheral surface of the outer cylinder is a surface of rotation around the center of rotation at least at the exhaust port.

Further, in the present invention, the feed rate of the powder or granular material in the tubular body can be adjusted by slightly inclining the tubular body and the outer cylinder without changing the inclination of the guide plate.
While the mechanism for changing the inclination angle of the plurality of guide plates is extremely difficult and complicated to operate in the furnace, the mechanism for inclining the cylindrical body and the outer cylinder is extremely simple and easy to operate.

[0041]

As described above, according to the present invention, the circulation path is formed by sealing the inner end of the tubular body and providing the partition wall having the guide plates inside except both ends.
It becomes a liquid by heating, and further vapor / gas is generated and the rest becomes powdery solid. Solid, filter cake, slurry and viscous liquid raw materials are heated substantially continuously for a long time. By doing so, it is possible to collect vapor and gas in a concentrated state and to discharge powdery solids substantially continuously, which may cause environmental pollution due to leakage of generated steam or gas or explosion due to air intake. In addition, the present invention brings about an effect that there is no danger such as destruction of a heated portion due to strength deterioration due to high temperature and high thermal efficiency and stable heating for a long period of time.
