Description

[0001] LIQUID DISTRIBUTOR [0002]

The present invention relates to a liquid distributor.

In some cases it may be necessary to supply liquid to a specific space to achieve a specific purpose. For example, when only a part of the components contained in the mixed gas is to be removed, a mixed gas may be supplied to the lower portion of the reaction vessel, and a liquid which reacts with the components to be removed may be supplied to the upper portion of the reaction vessel. Through the reaction in the reaction vessel of the mixed gas and the liquid, the mixed gas can be discharged to the upper part of the reaction vessel with the partial components removed, and the liquid can be discharged to the lower part of the reaction vessel. As another example, a liquid (cooling water) may need to be supplied to the specified object for cooling a specific object.

In such a case, a liquid distributor for uniformly distributing and supplying the liquid to a specific space may be required. In the case of the first example, if the liquid is uniformly supplied into the reaction vessel, the efficiency of the reaction inside the reaction vessel can be increased. Further, in the case of the second example, if the liquid is uniformly supplied to a specific object, the cooling efficiency of the specific object can be increased.

1 is a perspective view of a general liquid distributor 10. Fig. The liquid distributor 10 may include a plurality of sidewalls 11 and a space 12 between such sidewalls 11 may be utilized as a channel through which the liquid flows. The liquid may flow along the channel 12 and be discharged from the liquid distributor 10 through the outlet 14 formed in the bottom surface 13. As shown, since the outlet 14 is evenly formed over the entire area of the bottom surface 13, the liquid can be evenly distributed and exhausted to a specific space as it passes through the liquid distributor 10.

However, if such a general liquid distributor is used in a place where tilting occurs, the function of the liquid distributor may not be exhibited. For example, when the liquid distributor is used in a ship or a marine plant, the liquid inside the liquid distributor can be directed in a specific direction by the rocking of the ship or the offshore plant, thereby causing a change in the level of the liquid inside the liquid distributor . Such a change in the water level may cause a problem that the liquid is not uniformly distributed and supplied when the liquid passes through the liquid distributor. That is, a relatively large amount of liquid is discharged through a discharge port having a higher water level, and a relatively small amount of liquid can be discharged through a discharge port having a lower water level.

Hereinafter, specific embodiments for implementing the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the subject matter of the present invention.

2 is a schematic view of a channel section 130 of a liquid distributor according to one embodiment. The channel section 130 described herein may be one of a plurality of channel sections included in the liquid distributor. As will be described later, the liquid distributor may include a plurality of channel portions, and the channel portions may have a multi-layer structure. The channel portion 130 shown in FIG. 2 may be one of the channel portions (second channel portions) located relatively below the channel portions of the multi-layer structure.

The channel portion 130 may include a pair of side walls 131 and a bottom surface 132 facing each other. Thus, the channel portion 130 can function as a flow path through which the liquid can flow. A first outlet 133 may be formed in the bottom surface 132 and a liquid flowing in the channel 130 may be discharged through the first outlet 133. Since the first outlet 133 is formed in a plurality of places in the floor surface 132, the liquid can be uniformly distributed through the first outlet 133 and discharged.

A weir portion 150 may be provided at the upper end of the side wall 131. The whistler 150 may be configured to adjust the level of the liquid in the channel part 130. For example, if the supply of liquid is excessive or the discharge of liquid through the first outlet 133 is not smooth, the level of the liquid in the channel portion 130 may be increased, in which case the liquid may flow through the upper portion 150 The second outlet 151 and / or the third outlet 152, which are included in the first outlet 151 and / or the second outlet 152. A discharge port (not shown) may also be formed in the area outside the channel part 130, so that the liquid discharged through the whistle 150 may ultimately be discharged from the liquid distributor. A detailed description of the weir part 150 will be given again with reference to FIG.

In the channel unit 130, a flow rate control module 140 may be provided. The flow rate control module 140 may include a plate member 141, an elastic member 142, and a flow rate regulator 143.

The plate member 141 may be spaced upward from the bottom surface 132 by a predetermined distance. As shown in the figure, a plurality of plate members 141 are provided and may be spaced apart from each other along the extending direction of the channel unit 130.

At least two elastic members 142 may be provided to connect the bottom surface 132 and the plate member 141. [ In the present embodiment, it is assumed that four elastic members 142, which are illustrated as springs, are provided and interposed between the plate member 141 and the bottom surface 132. As will be described later in detail, the level of the liquid can be changed by the inclination of the liquid distributor, the load of the liquid applied to the plate member 141 can be changed by the change in the level of the liquid, The elastic member 142 may be compressed or elongated.

The flow rate regulator 143 has one side connected to the plate member 141 and the other side capable of closing a portion of the first outlet 133. In this embodiment, one side portion (reference upper end portion in FIG. 2) of the flow rate regulating member 143 is bonded to the lower surface of the plate member 141 as an example. In addition, the other side of the flow rate regulator 143 may be located above the first outlet 133, if necessary, so that the first outlet 133 may not be closed at all, 133 to close some areas of the first outlet 133. [ When the flow rate regulator 143 closes a part of the first outlet 133, the liquid is discharged from the first outlet 133, which is not closed by the flow rate regulator 143, of the entire area of the first outlet 133, As shown in FIG. On the other hand, the flow rate regulator 143 may be hemispherical, as shown in FIG. 2, in order to change the size of a partial region of the first outlet 133 closed by the flow rate regulator 143. That is, the cross-sectional area of the flow rate regulator 143 can be reduced from one side (upper end) to the other side (lower end). In this state, as the flow rate regulator 143 passes through the first outlet 133, the size of a part of the first outlet 133 and the remaining area can be changed. The shape of the flow rate regulator 143 does not necessarily have to be a hemispherical shape, but may be any shape as long as the diameter or cross-sectional area decreases toward the first discharge port 133, such as a cone, a triangular pyramid, or a quadrangular pyramid.

Fig. 3 is a view schematically showing the operation of the liquid distributor of Fig. 2; Fig. 3 (a) shows a state in which the liquid distributor is maintained in a horizontal state, and Fig. 3 (b) shows a state in which the liquid distributor is inclined.

3 (a), when the liquid distributor is in a horizontal state, the liquid level in the channel unit 130 may be the same throughout the entire area of the channel unit 130. That is, as shown, the liquid level can be located at a distance h1 upward from all the plate members 141. [ At this time, the flow rate regulator 143 may pass through the first outlet 133 and close a part of the first outlet 133. For example, as shown, the flow rate regulator 143 can close the area indicated by "11" in the entire area of the first outlet 133, Quot; d1 "area. And, according to the initial setting, the elastic member 142 may be compressed to some extent, stretched to some extent, and may maintain the initial length.

3 (b), when the liquid distributor is tilted, the liquid level in the channel part 130 may vary over the entire area of the channel part 130. [ When the liquid distributor is inclined to the right as shown in the drawing, the liquid level of the liquid can be positioned at a distance h2 upward from the plate member 141 at the rightmost flow control valve 143 side, The level of the liquid can be positioned at a distance of h3 from the plate member 141 at the flow control valve 143 side and the flow control valve 143 at the left- The liquid level can be located at a distance h1 from the plate member 141 upward. Here, the relationship of h2 > h1 > h3 can be satisfied.

Since the liquid level changes in this way, the load applied by the liquid to each plate member 141 can also vary. The load applied to the plate member 141 can be increased and the load applied to the plate member 141 can be reduced in the region where the water level is lowered. Each of the elastic members 142 can be compressed or elongated by such a change in load. 3 (b), the leftmost elastic member 142 can be elongated as compared with FIG. 3 (a) due to the reduction of the liquid load. The second elastic member 142 from the leftmost end does not change its length because there is no change in the liquid load. The rightmost elastic member 142 can be compressed compared to Fig. 3 (a) due to an increase in the liquid load.

The size of the closed portion of the first outlet 133 and the remaining unclosed portion can be varied by the change in the level of the liquid, the change in the load of the liquid, and the compression or extension of the elastic member 142. Hereinafter, Will be described.

The second leftmost flow control valve 143 closes a partial area ("11") of the entire area of the first outlet 133, the size of which can be almost the same as in FIG. 3 (a) . This is because the liquid level h1 is the same. 3 (a) due to the compression and expansion of the peripheral elastic member 142, the flow rate regulator 143 may be slightly inclined relative to the first outlet 133, The size of a partial area of the first outlet 133 closed by the first outlet 133 is almost the same as that of the case of FIG. 3 (a). Therefore, the size of the remaining area of the first outlet 133 through which the liquid can be discharged may be substantially equal to "d1" as in Fig. 3 (a).

The rightmost flow rate regulator 143 closes a partial region 12 of the entire region of the first outlet 133, the size of which can be increased compared to (a) of FIG. The flow rate regulator 143 is also lowered entirely by the compression of the elastic member 142 around the first discharge port 133 so that the first discharge port 133 can penetrate more than in FIG. As described above, the cross-sectional area of the flow rate regulator 143 can be increased as the flow rate increases. As a result, the size of the closed partial area 12 of the entire area of the first discharge port 133 can be increased ("L2"> "l1"). Therefore, the size of the remaining area d2 of the first outlet 133 through which the liquid can be discharged can be reduced ("d2" <"d1") as compared with FIG.

The leftmost flow rate regulator 143 closes a part of the entire region 13 of the first outlet 133, the size of which can be reduced compared to FIG. 3 (a). The elasticity of the elastic member 142 around the elastic member 142 also increases the flow rate regulator 143 so that the first outlet 133 can be penetrated less than in Figure 3 (a) The first outlet 143 may be located above the first outlet 133 and may not close the first outlet 133 at all). As described above, the cross-sectional area of the flow rate regulator 143 can be increased as the flow rate increases. As a result, the size of the closed partial area 13 of the entire area of the first discharge port 133 can be reduced ("L3" <"l1"). Therefore, the size of the remaining area d3 of the first outlet 133 through which the liquid can be discharged can be increased compared to Fig. 3 (a) ("d3"> "d1").

If the liquid distributor is tilted and the level of the liquid inside is changed, the flow rate of the liquid discharged through each outlet will vary depending on the level of the liquid even if the same size outlet is formed. That is, the flow rate of the discharged liquid is relatively large at the high water level, and the flow rate of the discharged liquid is relatively small at the low water level. Therefore, the flow rate of the liquid discharged from each discharge port varies, so that the liquid dispenser's original purpose of uniform distribution and supply of the liquid may not be achieved.

In the case of this embodiment, as described above, when the liquid distributor is inclined and the liquid level changes, the elastic member 142 is compressed or elongated in accordance with the change of the water level, and the first outlet 133 of the flow rate regulator 143 The size of the partial area of the first outlet 133 which is ultimately closed by the flow rate regulator 143 and the size of a portion of the first outlet 133 which is not closed by the flow rate regulator 143 The above problem can be solved because the size of the area can be changed. Specifically, since the size of a region where the liquid can be discharged is relatively small at a place where the water level is high and the size of a region where the liquid can be discharged is relatively large at a place where the water level is low, It can always be maintained uniformly.

FIG. 4 is a schematic view showing the operation of the liquid distributor of FIG. 2. FIG. Specifically, the liquid level in the channel unit 130 is adjusted through the whistling unit 150. (A), (b) and (c) can be referred to as a low-level state, a middle-level state, and a high-level state, respectively.

Generally, the weir portion 150 may include a raised portion and a valley portion which are repeated along the extending direction of the channel portion 130. And, when the level of the liquid increases, a part of the liquid can be discharged through the valleys.

4 (a), since the liquid level is below the upper end of the side wall 131 in the low water level state, the water level adjustment through the water leveler 150 may not be required. The liquid may be discharged through the first outlet 133 of the bottom surface 132.

4 (b) and 4 (c) show a case where the level of the liquid in the channel portion 130 is raised due to an excessive amount of the liquid supplied or the smooth discharge of the liquid through the first outlet 133 Lt; / RTI &gt; 4 (b), the liquid can be discharged primarily through the second outlet 151 of the upper portion 150. The second outlet 151 may have a rectangular cross-section when viewed from the opposite side wall (not shown), and the size thereof may be smaller than the third outlet 152 described later. 4C, the level of the liquid continuously increases, and the discharge passage through the second discharge port 151 may not be sufficient to control the level of the liquid. At this time, the liquid flows into the second discharge port 151, As well as secondarily through the third outlet 152. The third outlet 152 may be located above the second outlet 151 and may include an inverted trapezoidal cross section as viewed from the opposite side wall (not shown). Therefore, the cross-sectional area can be increased toward the upper side, and the overall size can be larger than the second discharge opening 151 as a whole. The third outlet 152 may be the last means by which the level of the liquid in the channel 130 can be adjusted, so that its size may be larger than the second outlet 151 and its size may become larger as it goes up .

FIGS. 5 and 6 are views schematically showing a plan view and a front view of the liquid distributor 100 of FIG. 2, respectively. As shown and as described above, the channel portions 120 and 130 may be provided in a plurality of layers to form a multi-layer structure. Also, a plurality of flow control modules 140 may be provided and a plurality of flow control modules 140 may be provided in each of the channel sections 120 and 130.

One of the plurality of channel portions 120 may be located at the top of the multi-layer structure. Therefore, any one of the channel units 120 can be supplied with liquid directly from the supply unit 110. In addition, any one of the channel units 120 may include only one channel unit, and may extend in a first direction (horizontal direction in FIG. 5).

The channel part 130 excluding the channel part 120 of the plurality of channel parts may be located at the bottom of the multi-layer structure. Therefore, the remaining channel part 130 can receive the liquid through the one of the channel parts 120. In addition, the remaining channel portion 130 may include a plurality of channel portions, which may extend in a second direction (reference vertical direction in FIG. 5) perpendicular to the first direction, and extend in a first direction Can be spaced apart.

With this structure, it is possible to uniformly distribute the liquid while maintaining the level of the liquid in each of the channel portions 120 and 130 at an appropriate level.

7 is a view schematically showing a flow control module 240 of a liquid distributor according to another embodiment. In the case of this embodiment, the floating body 242 can be used instead of the elastic member of the above-described embodiment. Hereinafter, the difference from the above-described embodiment will be mainly described.

Fig. 7 (a) shows a case in which the water level is relatively low. At this time, the floating body 242, which can be connected to the lower surface of the plate member 241, can be raised while providing a predetermined buoyancy to the plate member 241. The plate member 241 and the flow rate regulator 243 can also be lifted as the lifting body 242 rises. The movement of the float 242 can be guided by the guide member 260 and the float 242 can be moved by the protruding structure formed at the lower end of the float 242 and the upper end of the guide member 260, It may not rise above the height. The flow control valve 243 does not close the first discharge port 233 because the flow control valve does not show the case where the first discharge port is not closed. That is, when the floating body provided by the floating body 242 is larger in size than the load of the liquid, the floating body 242 can be raised and the flow control valve 243 is also raised so that the first outlet 233 is completely Can be opened. Accordingly, if the water level is relatively low, the remaining area of the first discharge port 233 through which the liquid can be discharged can be increased (the remaining area of the first discharge port 233 can be maximized as shown) .

Fig. 7 (b) shows a case in which the water level is relatively high. As the water level rises, the load of the liquid increases, and thus the float 242 can descend. The plate member 241 and the flow rate regulator 243 can also descend as the lifting member 242 descends and a part of the first outlet 233 closed by the flow rate regulator 243 can be generated have. As the flow rate regulator 243 further descends through the first outlet 233, the size of a portion of the first outlet 233 can be increased. At the same time, the size of the remaining area of the first outlet 233 through which the liquid can be discharged can be reduced. Therefore, in the case of FIG. 7 (b), although the water level is increased, the size of the space through which the liquid can be drained becomes smaller. As compared with the case of FIG. 7 (a), the liquid is discharged through the first outlet 233 The flow rate of the liquid may be the same.

According to the embodiments described above, even when the liquid distributor is inclined, liquid can be uniformly discharged through each outlet. Thus, the efficiency of the liquid distributor may be increased, and additional facility construction may not be required in case the liquid distributor is tilted. In addition, an additional control device is not required in consideration of the tilting of the liquid distributor, but the structure is simple and economical. In addition, since it is a very simple structure, the installation space is not limited, the possibility of occurrence of failure is low, and maintenance can also be advantageous.

It is to be understood that the embodiments described above are merely illustrative of some examples of the technical idea and the scope of the technical idea is not limited to the described embodiments, It will be understood that various changes, substitutions, and alterations may be made therein without departing from the spirit and scope of the invention.
