The present invention relates to a miniaturization / dispersion apparatus and a miniaturization / dispersion method.
[0002]
[Prior art]
Conventionally, it is described in Japanese Patent Laid-Open No. 9-60839 as a slurry-like material refinement / dispersion device for supplying and treating slurry sewage sludge having a water content of about 60 to 80% to an incinerator. Such supply nozzles are known.

[0003]
[Problems to be solved by the invention]
However, the slurry-like material miniaturization / dispersion apparatus as described in JP-A-9-60839 still has the following problems to be solved.
Since the injection of pressurized fluid to refine and disperse slurry sludge is only from the outer periphery of the sludge discharge port, there is a problem that the controllability of the sludge supply state (miniaturization, dispersion) is poor. It was. In the case of a solid circle, since it is supplied only from the outer periphery, sufficient shearing force does not work to the center, and in the case of a hollow ring, the sludge shape deformation occurs because it is only from the outer periphery, and the sharp shape It becomes a shape and the shearing force of the fluid is not sufficiently applied. As a result, there has been a problem that miniaturization cannot be performed sufficiently.
Further, since the pressurized fluid ejected from the pressurized fluid ejection port gathers in the central direction in the vicinity of the nozzle tip, it cannot be dispersed, and sludge concentrates on the central part and falls. Therefore, the reaction is slow and the processing load increases locally, so that there is a problem that only unstable and low-load processing can be performed.
In addition, although the effect is small, in order to refine and disperse sludge, a large flow rate of pressurized fluid is required, which causes a problem that the load on incidental equipment increases.

It will be ejected in the outer direction inclined at 90 °.
[0011]
Similarly to the inner tube 12, the central tube 17 uses a stainless steel pipe, and a connection flange 28 for connecting and fixing the inner tube 12 to the central tube 17 and a connection flange 29 connected to the connection flange 28 are provided at the base. ing. A pipe 31 and a connection flange 32 for cleaning the space 15 with water 30 are provided on one side of the base end portion of the central tube 17.

In addition, a slurry-like object spout 35 that ejects the slurry-like object 16 in an annular cross section is formed between the inside of the front part of the central tube 17 and the outer surface of the front part of the fluid outlet 13.
Therefore, the slurry-like material 16 sent by the slurry-like material supply means passes through the space 15 inside the central tube 17 and has a ring-shaped cross section through the slurry-like material ejection port 35 at the tip of the inner tube 12. Will be ejected in the axial direction.
[0012]

It is ejected in a direction inclined inwardly at the injection angle δ with respect to the axial direction of the outer tube 22.
[0013]
Next, the operation of the slurry-like material refinement / dispersion apparatus 10 according to the embodiment will be described.
First, as shown in FIG. 1, a method of attaching to a melting furnace 41 as an example of a processing furnace to which the slurry-like material refinement / dispersion apparatus 10 is applied will be described.
As shown in the drawing, a connection flange 44 and a mounting flange 45 are provided on a nozzle seat 43 formed through a refractory 42 at a location where the apparatus 10 for refining and dispersing slurry in the melting furnace 41 is installed. A flexible hose (not shown) is flange-connected to the connection flange 44, and cooling air 47 is supplied via the flexible hose. Attached to the mounting flange 45 is a mounting flange 46 fixed to the slurry-like material refinement / dispersion device 10. Thereafter, flexible hoses for supplying fluids 11 and 19 are connected to the connection flanges 23 and 38, respectively, and piping for supplying the slurry-like material 16 is connected to the connection flange 34 to complete the installation. .
A predetermined amount of the slurry-like material 16 is supplied into the high-temperature combustion chamber 48 of the melting furnace 41, and the slurry-like material 16 is refined and dispersed in the combustion chamber 48 so as to burn with high efficiency. It is operating while controlling the amount of 11 and 19.
[0014]
Next, the effect | action of refinement | miniaturization and dispersion | distribution of the slurry-like material by the refinement | miniaturization / dispersion apparatus 10 of slurry-like material is demonstrated, referring FIG.
The miniaturization and dispersion can be controlled mainly by increasing or decreasing the total amount of the fluids 11 and 19, changing the ratio of the amount of the fluids 11 and 19, and independently changing the amount of the fluids 11 and 19. .
As shown in FIG. 4, when the slurry-like material 16 flowing through the space 15 whose section is annular is ejected in parallel to the axial direction from the slurry-like object outlet 35, the slurry-like shape is a hollow columnar shape (shown by a broken line) whose section is annular. The fluid 11 is slanted from the fluid outlet 13 at the same time as the slant angle η10 to 90 ° in the flow direction (same as the axial direction) of the slurry-like material 16 from the inside of the material 16, and simultaneously from the outside of the hollow columnar slurry-like material 16 The fluid 19 is ejected from the fluid ejection port 21 at an inclination angle δ0 to 90 ° in the flow direction of the object 16.
[0015]
Regarding the behavior of the slurry-like material 16 at this time, if the fluid 11 is not flowed as in the conventional case, the slurry-like material 16 is contracted to the center by the fluid 19 in a state where the cross section is annular, The cutting by 19 cannot be performed sufficiently, and it will fall in the form of a large block. On the other hand, when the fluid 19 is stopped and only the fluid 11 is allowed to flow, the slurry-like material 16 diffuses radially from the central portion with the fluid 11 only in an annular cross section, and is dispersed to the outside. However, miniaturization with the fluid 11 is insufficient.
However, when the fluid 11 is ejected to the slurry-like material 16 from the inside of the slurry-like material 16 having an annular cross section like the slurry-like material miniaturizing / dispersing apparatus 10 according to the present embodiment, the slurry-like material 16 is disposed on both sides. Since a sufficient shearing force is applied by the fluids 11 and 19 ejected at an inclination from the top, the slurry can be sufficiently miniaturized and the slurry-like material 16 can be prevented from shrinking to the central portion and dispersed. Become.
[0016]
In particular, the slurry-like product 16 does not contract to the center and sufficient shearing force is applied by the fluids 11 and 19, so that the injection angle δ is different from the injection angle η, The number of jets of 19 is varied to optimize. That is, in order to perform appropriate miniaturization and dispersion, the ejection speed, ejection amount, and ejection angle of the fluids 11 and 19 under conditions such as the properties of the slurry 16, the ejection speed, and the cross-sectional shape to be ejected. It is necessary to appropriately determine conditions such as (inclination angles η, δ).
[0017]
When conditions such as the ejection speed, the ejection flow rate, and the ejection angle of each of the fluids 11 and 19 are appropriate and both are balanced, as the total ejection flow rate of the fluid 11 and the fluid 19 increases, The shearing force applied to the slurry-like material 16 by 19 increases, so that the slurry-like material 16 is particularly sufficiently refined. Further, since the fluids 11 and 19 are applied from both sides of the slurry-like material 16, the fluids 11 and 19 having a small shearing force, that is, a small flow rate can be miniaturized and dispersed.
On the other hand, when the ratio of the ejection flow rate of the fluid 11 and the fluid 19 is changed without changing the total ejection flow rate of the fluid 11 and the fluid 19, the fluid ejection port 13 of each of the fluid 11 and the fluid 19 is changed. , 21 can be changed to change the state of miniaturization and dispersion by changing the hole diameter, the number of holes, the inclination angle η, δ and the relative position. Moreover, the state of refinement | miniaturization and dispersion | distribution can also be changed by arbitrarily operating the flow volume of the fluids 11 and 19 independently.
[0018]
As described above, the miniaturization and dispersion of the slurry-like material 16 can be easily controlled by changing the ratio of the amounts of the fluids 11 and 19 or by increasing or decreasing the total ejection flow rate of the fluid 11 and the fluid 19. it can.
Accordingly, in the operation of the melting furnace 41 using the slurry-like material refinement / dispersion apparatus 10, the slurry-like product 16 is sufficiently refined, and thus the reaction can be speeded up by increasing the specific surface area. Since the slurry-like material 16 is sufficiently dispersed, it is possible to prevent a local increase in processing load, and as a result, stable and high-load processing in the melting furnace 41 is possible.
In addition, the slurry-like material refinement / dispersion device 10 basically has a triple-pipe structure, so that it can have a compact structure.
[0019]
In the present embodiment, the inner tube 12 and the fluid ejection part 14 are integrally attached in a fixed state. However, separately, a fluid ejection part moving means is provided to integrally or only the fluid ejection part. It is also possible to adjust the relative position of the fluid ejection port 13 formed in the fluid ejection part with respect to the fluid ejection port 21 formed in the annular plate 20 by moving in the axial direction. By adjusting the relative position, it is possible to effectively adjust the fineness and dispersion.
[0020]
In the present embodiment, the slurry-like material miniaturization / dispersion apparatus 10 basically has a triple-pipe structure, but as another embodiment, as shown in FIG. 5, it has a five-pipe structure. You can also. In this case, the annular plate 20a sandwiched between the slurry-like materials 16 and 16a passing therethrough has a plurality of two types of fluid jets 21a and 21b inclined in different directions with respect to the axial direction, with a predetermined interval in the circumferential direction. In the outermost annular plate 20b, a plurality of fluid ejection ports 21c inclined toward the slurry-like object 16a to be ejected are formed at predetermined intervals in the circumferential direction. Further, as a (2n + 1) heavy pipe structure (where n is an integer), fluid can flow in odd-numbered tubes from the center, and slurry can flow in even-numbered tubes. Note that the fluid and the slurry in each pipe may be the same or different. Moreover, although the fluid 19 is simultaneously ejected from the fluid ejection ports 21a and 21b, the partition pipe 55 shown with the broken line in the figure can be provided, and it can also be set as a different kind of gas, respectively, and the same gas is used. Also good.
[0021]
In the present embodiment, the flow path through which the fluid 11 flows has a circular cross section like the inner pipe 12, and the flow paths through which the slurry 16 and the fluid 19 flow are the inner pipe 12, the central pipe 17, and the central pipe 17, respectively. The outer tube 22 is formed in an annular shape in cross section, but is not limited to the shape of the flow path, and is shown in FIG. 6 as another embodiment according to conditions such as space constraints and slurry properties. Thus, it can also be configured to form a rectangular channel having an elongated cross section.
In particular, when the slurry-like material is ejected and the cross-section of the flowing slurry-like material ejection port and the flow channel is annular, the lengths of the annular inner periphery and the outer periphery are different, so uniform miniaturization and dispersion are achieved. For this, it is necessary to change the fluid ejection conditions (for example, ejection flow rate, ejection angle, ejection position, etc.) on both sides. In order to improve this point, it is necessary to form a rectangular channel having an elongated cross section.
In addition, the same code | symbol is attached | subjected about the same component, a subscript is changed about a similar component, and detailed description is abbreviate | omitted. Reference numerals 20c, 20d, and 20e in the figure denote fluid ejection plates in which a plurality of fluid ejection ports 21d, 21e, 21f, and 21g are formed in a linear direction at predetermined intervals.
[0022]
In each of FIGS. 5 and 6, the first-layer flow paths 50 and 50 a flow through the flow path of the fluid 11, and the second-layer flow paths 51 and 51 a flow through the flow path through which the slurry-like material 16 flows. The third layer channels 52 and 52a, the fourth layer channels 53 and 53a through which the slurry-like material 16a flows, the fifth layer channel 54 through which the fluid 49 flows, This will be referred to as 54a. The slurry-like material 16 and the slurry-like material 16a, and the fluid 11, the fluid 19 and the fluid 49 can be applied to the same or different materials.
[0023]
In the present embodiment, it has been described that the ejection of fluid is performed through a plurality of fluid ejection ports, but the present invention is not limited to this, and instead of the plurality of fluid ejection ports, slits in the circumferential direction of the tube are formed. You can also.
The slurry-like object spout 35 is constituted by a single slit, but it can also be constituted by a plurality of divided slits as necessary. A pipe for slurry-like material can be provided for each nozzle. Thus, if both the fluid and the slurry-like material are constituted by the ejection nozzle and the pipe, the layout and maintenance work of the apparatus becomes extremely easy.
Moreover, as a fluid, if it is compressed gas, it will not be limited to compressed air, Other gas can be used.
In the present embodiment, the case where the slurry-like material refinement / dispersion apparatus 10 is applied to the melting furnace 41 has been described. However, the slurry-like material such as sewage sludge is incinerated in an incinerator or the like, and the food-related In this field, the present invention can also be applied to a drying furnace for slurry-like materials.
[0024]
【Example】
The experimental conditions, experimental methods, and results of an example in which the slurry refinement / dispersion apparatus 10 according to the present embodiment is applied to the melting furnace 41 will be described.
The slurry 16 was sewage sludge with a water content of about 80%, the fluid 11 and the fluid 19 were compressed air, and the pressure was 0.1 to 3 kgf / cm ² .
The ejection angle η of the fluid ejection port 13 was 10 to 70 °, and the ejection angle δ of the fluid ejection port 21 was also 10 to 70 °.
[0025]
Under the conditions described above, the slurry 16 was supplied to the melting furnace 41 while changing the flow rate of the fluid 11 and the fluid 19 and the jetting angles η and δ.
As a result, by appropriately controlling the ejection flow rate and ejection angle η, δ of the fluid 11 and fluid 19, that is, by balancing both, the slurry-like material 16 can be easily refined by increasing or decreasing the total ejection flow rate. As a result, it was confirmed that stable melting treatment under a high load was possible as compared with the existing single tube-shaped nozzle.
[0026]
