Description

The present invention relates to a slag flow generator that generates a slag flow used for cleaning microreactors, millireactors, pipes, and the like.

For example, when two types of fluids that are immiscible with each other, such as water and oil, and water and air, flow inside the pipe, the first slag (first fluid phase) consisting of one fluid and the second fluid consisting of the other fluid. There is a flow method called slag flow in which two slags (second fluid phase) flow alternately along the pipe axis. This slag flow has characteristics different from those of other fluids, such as the fact that each slag flows independently when the entire slag flow is flowing, and the flow velocity between the vicinity of the pipe and the central part is almost the same. Therefore, it is used for cleaning microreactors and pipes by utilizing this characteristic.

For example, Patent Document 1 is a device that uses two flow paths that intersect in a Y-shape or a T-shape and generates a slag flow in which a slag flow is formed at the intersection, and is wide under arbitrary flow rate conditions. A slag flow generator that can adjust the length of each slag within a range is described.

Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the highest level concept of the present invention are not necessarily necessary for achieving the object of the present invention, but more. Described as constituting a preferred form.

FIG. 1 is a perspective view showing a slag flow generator.

FIG. 2 is a cross-sectional view showing the slag flow generator together with the liquid and the fluid.

As shown in these figures, the slag flow generator 100 is a device that generates a slag flow 200 in which the liquid slag 201 and the fluid slag 202 are alternately arranged to travel in the flow path, and the discharge pipe 101 and the casing The body 102, the supply pipe 103, the discharge pipe 104, and the adjusting means 105 are provided.

The discharge pipe 101 is a tubular member that discharges the liquid 211. The material forming the discharge pipe 101 is not particularly limited, and examples thereof include glass, metals (alloys) such as stainless steel, and resins. Further, since the shape of the discharge pipe 101 also changes depending on the slag flow 200 to be generated, the shape is not limited, but for example, when the slag flow 200 supplied to the microreactor is generated, the inner diameter is about 1 mm. An example is a circular tube of a size.

Here, the liquid 211 is a liquid that is a material of the liquid slag 201 that constitutes the slag flow 200, and is one of the fluids that are arbitrarily selected to form the desired slag flow 200. Specifically, for example, as the liquid 211, water, acetone, glycerin and the like can be exemplified.

Further, in the case of the present embodiment, the wall thickness of the discharge end 111, which is the end of the discharge pipe 101 from which the liquid 211 is discharged, is thinner than the wall thickness of the base end side of the discharge pipe 101. In the case of the present embodiment, a tapered surface is formed at the tip of the discharge pipe 101 so that the outer diameter of the discharge pipe 101 tapers toward the discharge end 111 while maintaining the inner diameter of the discharge pipe 101.

By reducing the wall thickness of the discharge end 111 in this way, it is possible to prevent the liquid 211 from adhering to the discharge end 111 as much as possible, and to discharge the liquid 211 from the discharge pipe 101 in a stable state.

The housing 102 is a box-shaped member that forms a flight space 120, which is a closed space in which the liquid 211 discharged from the discharge end 111 of the discharge pipe 101 flies. The material forming the housing 102 is not particularly limited, and examples thereof include glass, metals (alloys) such as stainless steel, and resins.

Here, the flight space 120 is a space surrounded by the housing 102, and is a closed space in which no fluid flows in or out except that the liquid 211 and the fluid 221 flow in and are discharged as the slag flow 200. is there.

Further, the “flying” of the liquid 211 means not only the state in which the liquid 211 flies in the flight space 120 as droplets, but also the liquid from the discharge end 111 of the discharge pipe 101 to the inner surface of the housing 102 as shown in FIG. It is used in the sense that the state in which 211 is continuous is also included.

In the case of the present embodiment, the housing 102 is integrated with the first housing portion 121 having a funnel-like shape and the large opening portion having a large diameter opening of the second housing portion 122, which are opposed to each other. The shape is as follows. A discharge pipe 104 is attached to a small opening which is a small diameter opening of the first housing portion 121. The discharge pipe 101 is coaxially inserted into the small opening of the second housing portion 122, and the annular opening formed between the discharge pipe 101 and the small opening of the second housing portion 122 is the fluid 221. Is the supply end 131 that flows into the flight space 120.

By arranging in this way, it is possible to match the flow direction of the liquid 211 (the negative direction of the Z axis in the figure) and the flow direction of the fluid 221 in the flight space 120. Further, depending on the shape and arrangement of the supply end 131, the fluid 221 flows coaxially so as to wrap around the liquid 211, so that the fluid 221 flows stably in the flight space 120 together with the liquid 211 and stabilizes the slag flow 200. It becomes possible to generate.

Further, in the case of the present embodiment, the housing 102 has the discharge pipe 101 and the discharge pipe so that the discharge direction of the liquid 211 discharged from the discharge pipe 101 and the inflow direction of the liquid 211 flowing into the discharge pipe 104 are aligned on one axis. 104 is connected. Further, the first housing portion 121 of the housing 102 is an opening of the first housing portion 121 on a surface orthogonal to the flight direction of the liquid 211 toward the inflow end 141 of the discharge pipe 104 along the flight direction of the liquid 211. A tapered surface portion 123 whose area is gradually reduced is provided. By providing the tapered surface portion 123 that gradually narrows toward the inflow end 141, the liquid 211 and the fluid 221 can smoothly flow into the discharge pipe 104. Even if the dimensional accuracy of the slag flow generator 100 is lowered to some extent, the state of the slag flow 200 to be generated can be adjusted with high reproducibility.

Here, the angle of the tapered surface portion 123 is preferably 45 ° or less with respect to the surface perpendicular to the pipe axis at the inflow end 141 of the discharge pipe 104. If it is larger than 45 °, for example, the distance between the discharge end 111 and the inner surface of the housing 102 changes significantly due to the deviation of the axis of the discharge pipe 101, which makes it difficult to generate a stable slag flow 200.

The supply pipe 103 is a member that supplies the flight space 120 with a fluid 221 that is different from the liquid 211. The material forming the supply pipe 103 is not particularly limited, and examples thereof include glass, metals (alloys) such as stainless steel, and resins. The shape of the supply pipe 103 is not particularly limited, but in the case of the present embodiment, the position of the supply end 131, which is a portion connected to the housing 102 of the supply pipe 103, is the position of the discharge pipe 104. It is arranged at a position farther than the discharge end 111 of the discharge pipe 101 with respect to the position of the inflow end 141. In the case of the present embodiment, the discharge pipe 101 is arranged coaxially at the end of the supply pipe 103, and the end of the discharge pipe 101 protrudes into the flight space 120 from the supply end 131. As a result, the positional relationship between the discharge end 111 and the supply end 131 is realized.

Further, the supply pipe 103 includes a coaxial portion 132 arranged coaxially with the discharge pipe 101 and a supply portion 133 that intersects the coaxial portion 132 and communicates with the coaxial portion 132. Further, the distance between the connecting portion between the coaxial portion 132 and the supply portion 133 and the supply end 131 is set to a distance at which the flow of the fluid 221 flowing through the coaxial portion 132 is stable. As a result, the fluid 221 flows into the flight space 120 in a stable state, and the slag flow 200 can be stably generated.

Further, the discharge pipe 101 is arranged in a penetrating state in the coaxial portion 132 of the supply pipe 103, and the discharge pipe with respect to the coaxial portion 132 is located farther from the portion intersecting the supply portion 133 with respect to the supply end 131. A sealing portion 134 that allows the 101 to slide and prevents the fluid 221 from leaking from between the discharge pipe 101 and the coaxial portion 132 is provided.

As described above, the coaxial portion 132 has a function of guiding the reciprocating movement of the discharge pipe 101 and sealing the housing 102, and it is preferable that the coaxial portion 132 has a sufficient length for ensuring this function. .. According to this, it is possible to generate a stable desired slag flow even when the dimensional accuracy of each member is poor.

The structure of the sealing portion 134 is not particularly limited, but for example, the slide and the sealing may be realized by grease, or the slide and the sealing may be realized by an O-ring or the like.

Here, the fluid 221 is a fluid that is a material of the fluid slag 202 that constitutes the slag flow 200, and is an arbitrarily selected substance that is difficult to mix with the liquid 211 in order to form a desired slag flow 200. .. It should be noted that "difficult to mix" does not mean that the slag flow 200 may flow for a certain length and does not completely mix. For example, since it is in a saturated state, a state in which the fluid 221 does not dissolve in the liquid 211 is included in a state in which it is difficult to mix.

Specifically, for example, as the fluid 221, a gas such as oxygen, carbon monoxide, or air, or a liquid such as silicon oil or vegetable oil can be exemplified.

The discharge pipe 104 is a tubular member that discharges the liquid slag 201 made of the liquid 211 and the fluid slag 202 made of the fluid 221 in an alternately arranged state. The material forming the discharge pipe 104 is not particularly limited, and examples thereof include glass, metals (alloys) such as stainless steel, and resins. Further, the shape of the discharge pipe 104 also changes depending on the slag flow 200 to be generated, and thus is not limited, but in the case of the present embodiment, the discharge pipe 104 flows in as it goes downstream of the slag flow 200. A diameter-expanded portion 142 whose inner diameter gradually increases from the inner diameter of the end 141 is provided. As a result, the contact area between the liquid slag 201 and the fluid slag 202 can be increased, and the reactivity can be enhanced when the liquid slag 201 and the fluid slag 202 are reacted.

Further, the discharge pipe 104 includes a curved portion 143. In order to improve the efficiency of slag flow 200 generation, the discharge direction of the liquid 211 in the flight space 120 is vertically downward, and the inflow end 141 of the discharge pipe 104 is arranged below the discharge end 111 of the discharge pipe 101, while the inflow end 141 of the discharge pipe 104 is arranged. A curved portion 143 is provided to change the flow direction of the slag flow 200 (the direction positive on the X-axis in the figure) in the horizontal plane in order to supply the slag flow 200 to the microreactor.

In the discharge direction of the liquid 211 of the discharge pipe 101 (Z-axis direction in the drawing), the adjusting means 105 has a reaching surface 124, which is an inner surface of the housing 102 hit by the liquid 211 that has flown in the flight space 120, and a discharge end of the discharge pipe 101. This is a device that adjusts the distance d from 111. In the case of this embodiment, the position of the reaching surface 124 and the position of the inflow end 141 are the same.

In the case of the present embodiment, the adjusting means 105 has a first connecting portion 151 that is fixedly connected to the housing 102 via the coaxial portion 132 of the supply pipe 103, and a discharge that protrudes from the coaxial portion 132 and is exposed. The second connecting portion 152, which is fixedly connected to the pipe 101, freely rotates with respect to the first connecting portion 151 without changing its position, and is screwed with the female screw provided through the second connecting portion 152. It is composed of a shaft body 153 provided with a male screw portion and a knob 154 for rotating the shaft body 153 with a finger or the like.

By rotating the knob 154 of the adjusting means 105, the shaft body 153 can be rotated to change the distance between the first connecting portion 151 and the second connecting portion 152, and the discharge pipe 101 fixedly connected to these can be changed. The distance between the discharge end 111 and the reaching surface 124 of the housing 102 can be arbitrarily changed.

The adjusting means 105 is not limited to the mechanism as described above, and even when the discharge pipe 101 is manually moved with respect to the housing 102, the discharge pipe 101 is maintained in a sealed state of the flight space 120. The mechanical portion capable of adjusting the protruding state is the adjusting means 105. Further, the distance d can be controlled by connecting a rotating means such as a motor so that the knob 154 can be automatically rotated.

FIG. 3 is a diagram schematically showing an experimental device for observing the state of the slag flow generated by the slag flow generator.

As shown in the figure, the experimental apparatus 300 includes a pump 301 capable of continuously supplying the liquid 211 stored in the storage tank 302 to the discharge pipe 101 of the slag flow generator 100 at a predetermined flow rate, and a fluid. A flow rate adjusting means 303 capable of continuously supplying 221 to the supply pipe 103 of the slag flow generator 100 at a predetermined flow rate, and a high-speed camera capable of capturing the state of the slag flow 200 generated by the slag flow generator 100. It is equipped with 304.

The liquid 211 used in this example is three types of acetone, water, and glycerin. Further, as the fluid 221, oxygen which is a gas is used.

The pump 301 was set so that any liquid 211 could be supplied at a flow rate of 3 ml / min.

The flow rate adjusting means 303 was set so that the gaseous oxygen stored in the cylinder could be depressurized and supplied at a flow rate of 20 ml / min.

Under the above conditions, the state of the slag flow 200 when the distance d between the reaching surface 124, which is the inner surface of the housing 102, and the discharge end 111 of the discharge pipe 101 is 3.8 mm, and the distance d is 2.0 mm. The state of the slag flow was observed with the high-speed camera 304.

The observed results are shown in Table 1.

As described above, when the flow rates of the liquid 211 and the fluid 221 supplied to the slag flow generator 100 are constant, the liquid slag 201 can be obtained by changing the distance d between the reaching surface 124 and the discharge end 111. The slag length of the fluid slag 202 can be adjusted, and the ratio of the slag length of the liquid slag 201 to the slag length of the fluid 221 can be adjusted.

Further, in the case of glycerin having a relatively high viscosity of the liquid 211, by finely adjusting the distance d between the reaching surface 124 and the discharge end 111, slag flows 200 in various states are generated as shown in Table 2 below. I was able to.

When the liquid 211 and the fluid 221 having a constant flow rate are supplied to the two flow paths by using the conventional slag flow generation member consisting of T-shaped or Y-shaped intersecting flow paths, each slag length and slag The length ratio cannot be changed.

According to the slag flow generator 100 described above, not only the flow rate and pressure of the supplied liquid 211 and the fluid 221 but also the discharge of the reaching surface 124 and the discharge pipe 101 where the liquid 211 flying in the flight space 120 hits. The distance d from the end 111 can be used as a parameter, and the slag length of the liquid slag 201 and the slag length of the fluid slag 202 can be set individually. Further, it is possible to generate the slag flow 200 in various states without preparing a plurality of slag flow generation devices.

Therefore, by subjecting the slag flow 200 generated by the slag flow generator 100 to the microreactor, the reaction between the liquid slag 201 and the fluid slag 202 can be arbitrarily manipulated.

The invention of the present application is not limited to the above-described embodiment. For example, another embodiment realized by arbitrarily combining the components described in the present specification and excluding some of the components may be the embodiment of the present invention. In addition, the present invention also includes modifications obtained by making various modifications that can be conceived by those skilled in the art within the scope of the gist of the present invention, that is, the meaning indicated by the wording described in the claims, with respect to the above-described embodiment. Is done.

For example, as shown in FIG. 4, the housing 102 may have a bottomed cylindrical shape or the like. Further, the reaching surface 124, which is the inner surface of the housing 102 to which the flying liquid 211 hits, may be a plane intersecting (orthogonal) with respect to the flight direction of the liquid 211.

Further, the shape of the housing 102 can be any shape such as a hollow sphere or a hollow cube.

Further, the supply pipe 103 may be directly connected to the housing 102 and supply the fluid 221 in the direction of crossing or twisting the flight direction of the liquid 211.

Further, the discharge pipe 104 may be directly connected to the housing 102 without providing the enlarged diameter portion 142. In this case, the pipe shaft of the supply pipe 103 and the pipe shaft of the discharge pipe 104 may be arranged coaxially.

Further, as shown in FIG. 5, in the liquid 211 passing through the discharge pipe 101, a liquid repellent portion 112 made of a material having a wettability worse than that of the material constituting the discharge pipe 101 is provided at least at the discharge end 111. It doesn't matter. As a result, the liquid 211 discharged from the discharge pipe 101 is separated well, and the state of the generated slag flow 200 can be stabilized. The material of the liquid-repellent portion 112 is not particularly limited, and for example, a fluororesin can be exemplified.

Further, the discharge direction of the liquid 211 by the discharge pipe 101 is not limited to the vertically downward direction, and may be set in any direction such as a horizontal direction or an oblique direction with respect to the horizontal plane.

Further, even when the fluid 221 is a liquid, the space formed by the housing 102 is the flight space 120, and the liquid 211 discharged from the discharge pipe 101 is expressed as flying in the flight space 120.
