FIG. FIG. 5 is an enlarged view of a part of the embodiment in which a large number of comminuted mixing elements in the same as above are planted in a strip and the strip is fitted to the mixing chamber side of the spiral flow path to thereby arrange the spiral flow path. FIG. FIG. 6 is a side view showing a separated state of different liquids in the mixing chamber. FIG. 7 is a front view of the above. FIG. 8 is a partially omitted vertical sectional front view showing the vertical type embodiment of the above.

In the horizontal type embodiment shown in FIG. 1, reference numeral 1 is a cylindrical mixing chamber, the cross-sectional area of which is determined according to the flow rate of the liquid, and the length is desired to be the liquid while flowing inside. The mixing chamber 1 is provided with a liquid inflow port 2 below one end and a liquid outflow port 3 above the other end. Further, the inner cylinder 4 is inserted and fitted in the center.

Reference numeral 5 designates a spiral member provided in the mixing chamber 1, the outer periphery of which is in contact with the inner surface of the mixing chamber 1 and the inner periphery of which is in contact with the outer surface of the inner cylinder 4, as shown in FIGS. A spiral flow path 6 as shown in FIG. 7 is formed in the mixing chamber 1 to greatly extend the flow path of the liquid in the mixing chamber, and the spiral body 5 mixes the liquids having a specific gravity difference. operation mixed liquid when it stops caused the separation of, 6 by specific gravity difference, when present in the mixing chamber 1 make the boundary line a as shown in FIG. 7, finely underside of the liquid boundary line a Since the dividing chamber is divided, and the dividing action by the dividing chamber is continued until the angle at which the liquid is transferred from the upper chamber to the lower chamber by tilting the mixing chamber 1, the mixing chamber 1 moves from the horizontal position to the above-mentioned state. It can be used within the range up to the tilted position of the specified angle.

Reference numeral 7 denotes a large number of crushing / mixing elements arranged in the spiral flow path 6, which are arranged in a zigzag shape as closely as possible as shown in FIG. It is ensured that the element 7 acts on the liquid and these elements 7
As shown in FIG. 4, the attachment can be performed by vertically implanting the inner cylinder 4 as shown in FIG. 2, or by horizontally attaching the spiral body 5 to the inner cylinder 4 as shown in FIG. It is planted and placed in the strip 9 that fits the width of the spiral flow path 7 and is limited to the inner cylinder 5 side of the flow path 7 as shown in FIG. 4 or the mixing means of the flow path 5 as shown in FIG. Of course, other attachment means can be selected and used.

The crushing / mixing element 7 is not limited to a straight wire as shown in FIGS. 1 to 5, and although the drawing is omitted, a wire bent in a zigzag shape or the like may be used. Further, as shown in FIGS. 1 to 5, without arranging the arrangements vertically or horizontally at the same angle, the inclination is alternately changed to allow the front and rear wire rods to have a tolerance. It is necessary to devise various means to improve the mixing efficiency. Even in this horizontal type mixing device, the crushing mixing element 7
Alternatively, a fixed-width wire rod used in the vertical type of FIG. 8 may be sandwiched between two wires and twisted to form a brush in which the wire rod spreads radially, and this brush may be disposed in the spiral flow path 7. It is possible.

Reference numeral 9 denotes an oil heater for heating the inner cylinder 4 inserted into the mixing chamber 1, which heats the oil and circulates the oil in the inner cylinder 4 through the pipe lines 10 and 11, thereby allowing the liquid in the mixing chamber 1 to flow. Is maintained at a temperature suitable for the processing of crushing and mixing, and the heating of the inner cylinder 4 by this is also transmitted to the spiral body 5 and the stirring and mixing element 7, and is transmitted to the liquid from these to efficiently and evenly heat the liquid. It is effective to do. However, this heater 9 is not necessary for liquids that can be pulverized and mixed at room temperature or below, and the heating means is not limited to the oil heater 9, and an electric heater or the like can be inserted into the inner cylinder 4. It can be used, and a means for heating the mixing chamber 1 from the outside may be adopted if necessary.

When the fuel oil and the water component (water with an emulsifier added) are supplied from the inlet 2 of the horizontal mixing apparatus shown in the above embodiment, these liquids are guided to the spiral body 5. While colliding with the large number of pulverizing / mixing elements 7 while flowing in the spiral flow path 6 in which the large number of pulverizing / mixing elements 7 are arranged, an operation of finely crushing by this and an operation of mixing by disturbance are performed. The water component is repeatedly applied thousands of times or tens of thousands of times depending on the number of the elements 7, and in particular, the water component is made into fine particles of a micron unit and uniformly dispersed and mixed in the fuel oil to emulsify the fuel oil. Continuous production of homogeneous and stable emulsion fuel.

Further, in this apparatus, even if the fuel oil and the water component are separated because the mixing operation is stopped for a long time, the water component having a large specific gravity is below the boundary line a as shown in FIGS. 6 and 7. Moreover, in this state, the respective compartments partitioned by the spiral body 5 are in the same state. Therefore, if the liquid outlet 3 is provided above the mixing chamber 1 as shown in FIG. Fuel oil containing only water component or excess water component is not sent to the combustor, but when the mixing is restarted, the fuel oil and water component in each compartment are mixed and completely emulsified and then sent to the combustor. It has a characteristic that this function is exerted not only when it is installed horizontally but also at an inclination angle within a range in which the transfer of liquid from the upper compartment to the lower compartment does not occur.

Further, when the fuel oil is heavy and needs to be heated, when the inner cylinder 5 is heated by the oil heater 9, the heat is applied to the spiral body 6 and the crushing mixing element 7 in the fuel oil. The fuel oil is also transmitted to the fuel oil and the like, so that the fuel oil is efficiently and uniformly heated, which contributes to the promotion of emulsification and the improvement of fluidity.

In the vertical type embodiment shown in FIG. 8, reference numeral 1 denotes a cylindrical mixing chamber, the cross-sectional area of which is determined according to the flow rate of liquid, and the length of which is desired to be crushed and mixed while flowing inside. It has been determined that the results can be obtained. In the lower part of the mixing chamber 1, an unmixing section 12 is provided, in which the extension section 13 of the liquid inlet 2 is made to rise. 13 is covered with the shielding cup 14 upside down, and the liquid rising from the extension 12 descends through the gap between the shielding cup 14 and the outside of the cup 14, and rises to the mixing chamber 1. A liquid outlet 3 is provided at the center of the upper end of 1.

A spiral body 5 having a mandrel 15 is arranged in the mixing chamber 1 to form a spiral flow path 6 in the mixing chamber 1, and a wire material having a predetermined length is provided in the spiral flow path 6. A well-known brush, which is formed by radially spreading the wire rod by sandwiching and twisting the cut wire into two wires 16, is housed as the crushing and mixing element 7. However, the crushing / mixing element 7 is not limited to the brush, but it is needless to say that the crushing / mixing element 7 having the structure used in the horizontal type embodiment or another suitable structure can be used.

The apparatus shown in the above-mentioned embodiment has the inlet 2
When fuel oil and a water component obtained by adding an emulsifier to water are supplied from the above, when these liquids rise from the non-mixing section 12 to the mixing chamber 1, they are guided by the spiral body 5 and a large number of comminuted mixing elements 7 are arranged. The water component flows through the spiral flow path 6, collides with a large number of comminuting and mixing elements 7 during this period, and is finely crushed, and the operation of being mixed by being disturbed is repeatedly performed thousands or tens of thousands of times. Is micronized into fine particles and uniformly dispersed and mixed in fuel oil to continuously produce a homogeneous and stable emulsion fuel.

Moreover, in this apparatus, even if the fuel oil and the water component are separated to stop the mixing operation, the water component having a large specific gravity is accumulated in the non-mixing section 12 as shown in FIG. Since only fuel oil is stored in No. 1, only fuel oil initially in the mixing chamber 1 is sent to the combustor when mixing is restarted, so ignition is reliably performed with pure fuel, and after that, mixing is performed. The water component of the portion 12 rises to the mixing chamber 1 and is mixed with fuel oil to form an emulsion fuel, which is sent to the combustor.
