Technical Field

[0001] The utility model relates to a gas-liquid separator. Background Art

[0002] As a gas-liquid separator, for example, Patent Document 1 describes a separator that separates water contained in anode exhaust gas discharged from the anode of a fuel cell.

[0003] Patent Document 1 discloses the following structure: The gas-liquid separator uses a flow path member inside the housing to vertically convey the water-containing gas supplied from an inlet formed in the lower part of the housing, and makes it contact a plurality of separation vanes in the gas-liquid separation part disposed in the upper part of the housing, thereby generating a vortex to separate water.

[0004] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2022-112483

[0005] The gas-liquid separator described in Patent Document 1 reduces the pressure loss in the gas-liquid separation part and generates a vortex that makes the water-containing gas swirl, and improves the separation performance by making the water-containing gas contact a plurality of separation vanes.

[0006] However, in the case where an inlet is provided in the lower part of the housing, a space where the water-containing gas can swirl is formed in the upper part of the housing and has a plurality of separation vanes. Such a structure requires a flow path (flow path member) that allows the gas to flow longitudinally. Therefore, it may cause a pressure loss in the gas-liquid separation part. Summary of the Utility Model

[0007] For this reason, there is a need for a gas-liquid separator that can reduce the pressure loss in the gas-liquid separation part and separate water from the water-containing gas.

[0008] The characteristic structure of the gas-liquid separator of the present utility model has: a housing having a water storage space on the lower side; an inlet connected to the lower part of the housing and introducing the water-containing gas; an inclined guiding part guiding the water-containing gas supplied from the inlet into the housing to a position above the water storage space; and a separation plate having a comb-shaped contact surface extending in the vertical direction and contacted by the water-containing gas when colliding, and separating the water contained in the water-containing gas by the collision of the water-containing gas guided by the inclined guiding part with the contact surface.

[0009] According to this structure, the water-containing gas introduced into the introduction port is guided by the inclined guiding portion to a position above the water storage space, and collides with the comb-shaped contact surface of the separation plate, thereby separating the water. In addition, for example, this separation structure does not require a space for swirling the water-containing gas as a vortex, a plurality of blade-shaped members contacted by the vortex, and a flow path (an additional flow path member) for allowing the gas to flow longitudinally, and can perform good water separation. Therefore, a gas-liquid separator is constituted that can reduce the pressure loss in the gas-liquid separation portion and separate water from the water-containing gas.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, an embodiment of the gas-liquid separator of the present utility model will be described based on the accompanying drawings. In this embodiment, it is not limited to the following embodiments, and various modifications can be made without departing from the gist thereof.

[0023] 〔Basic Structure〕

[0024] As Figures 1 to 3 shown, it has an inlet 1 connected to the side surface of a resin-made housing 10, an outlet 2 on the upper surface of the housing 10, a gas-liquid separation part As and a water storage part At inside the housing 10. The gas-liquid separation part As separates water from anode exhaust gas (an example of water-containing gas), and the water storage part At recovers the water separated by the gas-liquid separation part As into a water storage space T. An electromagnetic on-off valve 3 for discharging the water in the water storage part At is provided on the outer surface of the bottom of the housing 10, thus constituting a gas-liquid separator A.

[0025] In this gas-liquid separator A, the inlet 1 communicates with a separation space S inside the housing 10, and the outlet 2 communicates with a space in the internal space of the housing 10 where dehydrated gas etc. supplied with the dehydrated gas transported from the separation space S is located.

[0026] This gas-liquid separator A functions as follows: by introducing anode exhaust gas (water-containing gas) discharged from a fuel cell in a fuel cell vehicle (FCV) from the inlet 1, the water contained in the anode exhaust gas is separated and recovered into the water storage part At, and the dehydrated gas etc. after separating the water is discharged from the outlet 2. In addition, in the following description, since the water-containing gas after separating water by the gas-liquid separator A contains a small amount of water, it is sometimes also referred to as dehydrated gas etc.

[0027] The dehydrated gas etc. discharged from the gas-liquid separator A contains unreacted hydrogen. For this reason, the fuel cell vehicle (FCV) supplies dehydrated gas etc. to the flow path on the anode side of the fuel cell by using the gas-liquid separator A, achieving waste-free hydrogen reuse.

[0028] 〔Housing〕

[0029] As Figures 1 to 3 shown, the housing 10 is composed of an upper housing 11 and a lower housing 12. The housing 10 is integrated by fastening an upper flange 11f formed on the upper housing 11 and a lower flange 12f formed on the lower housing 12 with a plurality of bolts.

[0030] The upper housing 11 has an upper side wall 11a surrounding the entire circumference of the upper housing 11, and has an outlet 2 extending upward from an upper wall 11p. The gas-liquid separation part As is arranged below an intermediate wall 11q at a position lower than the upper wall 11p in the upper housing 11.

[0031] The lower housing 12 has a lower side wall 12a that surrounds the entire circumference of the lower housing 12, and has an inlet 1 that extends horizontally from the lower side wall 12a. The lower housing 12 has an inclined guiding portion 13 that guides the water-containing gas fed from the inlet 1 to a position above the water storage space T, and a water storage portion At for storing water in the water storage space T is formed at the bottom of the lower housing 12.

[0032] The lower housing 12 has a funnel-shaped bottom wall 12b with a smaller cross-sectional area towards the lower side. The water storage portion At has a water storage space T in the funnel-shaped bottom wall 12b, and a discharge path 4 is formed at the lower end. An electromagnetic on-off valve 3 for opening and closing the discharge path 4 is provided on the outer surface of the bottom of the lower housing 12.

[0033] 〔Gas-liquid separation portion〕

[0034] The gas-liquid separation portion As has: an inclined guiding portion 13 that guides the water-containing gas to a position above the water storage space T as shown in Figure 2 、 Figure 5 ; a separation plate P that has a comb-shaped contact surface as shown in Figure 2 、 Figure 4 、 Figure 6 and separates the water contained in the water-containing gas by contacting the water-containing gas with the comb-shaped contact surface.

[0035] The separation plate P is composed of a first main body portion 15 in the shape of a vertical wall and a second main body portion 16 in the shape of a vertical wall, and has these main body portions (the superordinate concept of the first main body portion 15 and the second main body portion 16) extending downward from the inner surface of the intermediate wall 11q of the housing 10.

[0036] The main body portions (the first main body portion 15 and the second main body portion 16) are in the following positional relationship: the upper ends are connected to the inner surface side of the intermediate wall 11q of the upper housing 11, and the lower ends are inserted into the inner space of the lower housing 12. In addition, as shown in Figure 6 , the first main body portion 15 and the second main body portion 16 are arranged at positions surrounding the inclined guiding portion 13 in a top view.

[0037] The first main body portion 15 forms a contact surface that extends in the vertical direction in a comb shape and is contacted by the water-containing gas during collision through a plurality of convex portions 15a that extend in the direction towards the inclined guiding portion 13 in a top view and extend in the vertical direction along the vertical direction. In addition, the comb-shaped contact surface can be formed not only on the first main body portion 15 but also on the second main body portion 16.

[0038] As shown in Figure 6As shown in the figure, the first main body portion 15 and the second main body portion 16 are connected such that their respective wall surfaces are substantially at right angles when viewed from above. The gas-liquid separation portion As forms a separation space S in a region surrounded by the first main body portion 15, the second main body portion 16, and the side wall portion of the housing 10 (the upper concept of the upper side wall 11a and the lower side wall 12a) in a region extending in the vertical direction. In addition, the inclined guide portion 13 is disposed at a position overlapping the separation space S when viewed from above.

[0039] As Figure 2 , Figure 5 shown in the figure, the inclined guide portion 13 has a guide surface 13a that is arc-shaped when viewed from the side and is open at the upper side, so as to guide the water-containing gas supplied in the horizontal direction from the inlet 1 upward. The inclined guide portion 13 is integrally formed on the bottom wall 12b so as to protrude upward from the bottom wall 12b in the internal space of the lower housing 12.

[0040] The first main body portion 15 is disposed at a position in direct contact with the water-containing gas guided by the guide surface 13a. By causing the water-containing gas guided by the guide surface 13a and flowing upward to flow along a plurality of convex portions 15a, the water-containing gas is brought into contact with the convex portions 15a to achieve water separation.

[0041] The first main body portion 15 expands the surface area of the contact surface by a plurality of convex portions 15a. Since the plurality of convex portions 15a are in an up-and-down posture, there is no large resistance when the water-containing gas flows upward.

[0042] As Figure 2 , Figure 6 shown in the figure, the gas-liquid separation portion As has a first gap C1 (an example of a discharge space) between the upper wall 11p and the bottom wall 12b of the housing 10 at an end position of the first main body portion 15 on the side opposite to the second main body portion 16. The gas-liquid separation portion As has a second gap C2 (an example of a discharge space) between the upper wall 11p and the bottom wall 12b of the housing 10 at an end position of the second main body portion 16 on the side opposite to the first main body portion 15.

[0043] As Figure 2 , Figure 4 , Figure 6 shown in the figure, the gas-liquid separation portion As has a collision plate 17 extending in a form from the separation plate P in the second main body portion 16. The collision plate 17 protrudes from the inner surface of the intermediate wall 11q (the upper inner surface of the housing 10) toward the separation space S (downward). The collision plate 17 extends obliquely starting from an end position of the second main body portion 16 on the side opposite to the first main body portion 15 in a manner away from the side wall of the housing 10.

[0044] According to this structure, the gas-liquid separator A causes the water-containing gas supplied from the inlet 1 to collide with a plurality of convex portions 15a of the first main body portion 15, thereby separating the water contained in the water-containing gas. In addition, the gas-liquid separator A conveys the dehydrated gas from which water has been separated, etc. from the first gap C1 and the second gap C2 to the outside of the separation space S. That is, the gas-liquid separator A causes the dehydrated gas, etc. to flow from both side portions of the gas-liquid separation portion As to the outside of the separation space S and finally discharges it from the discharge port 2.

[0045] As Figure 2 shown, the gas-liquid separation portion As forms a gap G in the lower housing 12, and this gap G is located between the inclined guide portion 13 and the inner surface of the lower side wall 12a of the portion where the inlet 1 is formed. This gap G prevents the backflow of the water-containing gas, for example, when the pressure upstream of the inlet 1 temporarily drops or when the pressure inside the housing 10 temporarily rises.

[0046] In addition, since the gas-liquid separator A is provided with the inclined guide portion 13 on the lower side of the separation space S, a part of the water separated from the water-containing gas sometimes flows into the gap G. Therefore, as Figure 2 , Figure 3 , Figure 5 shown, a recovery flow path 5 for sending the water that has entered the inside of the gap G into the water storage portion At is formed in a region connected to the bottom of the gap G.

[0047] This recovery flow path 5 causes the water separated from the water-containing gas to flow toward the water storage portion At by utilizing the inclination of the bottom wall 12b of the lower housing 12. In addition, the electromagnetic on-off valve 3 remains closed in the non-energized state and discharges the water stored in the water storage portion At by making the discharge path 4 communicate when energized.

[0048] 〔Functions and effects of the embodiment〕

[0049] In this way, the gas-liquid separator A guides the water-containing gas introduced into the inlet 1 upward in a state of contacting the guide surface 13a of the inclined guide portion 13 inside the housing 10, and when the water-containing gas rises in the separation space S, it contacts the comb-shaped contact surface of the gas-liquid separation portion As, and the water is separated.

[0050] In particular, the separation space S restricts the flow of the water-containing gas by using the longitudinal wall-shaped first main body portion 15 and the longitudinal wall-shaped second main body portion 16, thus suppressing the adverse situation of the water-containing gas leaking short-circuit from the separation space S to the outside.

[0051] In addition, when the water-containing gas conveyed upward from the inclined guide portion 13 rises along the separation space S in the gas-liquid separation portion As, the gas-liquid separation portion As causes the water-containing gas to contact the surface of a plurality of convex portions 15a, and the water is separated.

[0052] That is, since the comb-shaped contact surface is composed of a plurality of convex portions 15a of the first main body portion 15, a wide contact surface is formed to improve the water separation performance. The gas-liquid separation portion As is miniaturized as compared with, for example, a structure in which a vortex is generated and the water is separated by contacting a plurality of separation vanes or the like.

[0053] The water that has been dropletized by the contact of the water-containing gas with the surfaces of the plurality of convex portions 15a easily moves downward along the surfaces of the convex portions 15a and is received by the bottom wall 12b of the lower housing 12, and flows toward the water storage portion At by the inclination of the bottom wall 12b.

[0054] In addition, the dehydrated gas and the like after water separation in the separation space S flow into the first gap C1 and the second gap C2, and finally are discharged from the discharge port 2.

[0055] Since the gas-liquid separation portion As has the collision plate 17 protruding downward from the lower surface of the intermediate wall 11q, when the water-containing gas flowing upward in the separation space S reaches the intermediate wall 11q and flows in the direction of the second gap C2, the outflow of the water-containing gas is suppressed by contacting the collision plate 17, and the water contained in the water-containing gas can be separated.

[0056] A gap G is formed between the inclined guide portion 13 and the inner surface of the lower side wall 12a of the lower housing 12 of the gas-liquid separation portion As, and a recovery flow path 5 is formed in a region connected to the bottom of the gap G. Therefore, the backflow of the water-containing gas inside the housing 10 toward the inlet 1 is prevented, and when the water separated from the water-containing gas enters the gap G, the water is supplied from the recovery flow path 5 to the water storage portion At and stored.

[0057] 〔Another Embodiment〕

[0058] In addition to the above-described embodiment, the present invention can also be configured as follows (parts having the same functions as those in the embodiment are labeled with the same numbers and reference numerals as those in the embodiment).

[0059] (a) As shown in Figures 7 to 9 , a gas-liquid separator A is formed by having an inlet 1 on the side surface of a resin housing 10, a discharge port 2 on the upper surface of the housing 10, a gas-liquid separation portion As and a water storage portion At inside the housing 10, the gas-liquid separation portion As separating water from anode exhaust gas (an example of water-containing gas), the water storage portion At recovering the water separated by the gas-liquid separation portion As into a water storage space T, and having an electromagnetic on-off valve 3 for discharging the water in the water storage portion At on the outer surface of the bottom of the housing 10.

[0060] The gas-liquid separator A of this other embodiment (a) is the same as the gas-liquid separator A described in the embodiment. By supplying the anode exhaust gas (water-containing gas) discharged from the fuel cell mounted on the fuel cell vehicle (FCV) to the inlet 1, the water contained in the anode exhaust gas is separated, and the dehydrated gas after water separation is discharged from the outlet 2.

[0061] The housing 10 of the gas-liquid separator A of this other embodiment (a) is composed of an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are integrated by fastening the upper flange 11f and the lower flange 12f with a plurality of bolts.

[0062] The gas-liquid separation part As has: an inclined guiding part 13 that guides the water-containing gas to a position above the water storage space T; a separation plate P that has a comb-tooth-shaped contact surface, and separates the water contained in the water-containing gas by contacting the comb-tooth-shaped contact surface. The inclined guiding part 13 is formed integrally with the lower housing 12 as a cylindrical flow path that guides the water-containing gas obliquely upward, and supplies the water-containing gas to a separation space S that is long in the longitudinal direction.

[0063] As Figure 9 、 Figure 10 shown, the separation plate P has a first main body part 15 in the shape of a vertical wall and a second main body part 16 in the shape of a vertical wall. These main body parts (the superordinate concept of the first main body part 15 and the second main body part 16) extend downward from the inner surface of the intermediate wall 11q of the housing 10.

[0064] As Figure 9 shown, the wall surfaces of the first main body part 15 and the second main body part 16 are connected at a relatively large angle (obtuse angle) when viewed from above. The first main body part 15 is arranged at a position directly contacted by the water-containing gas guided by the inclined guiding part 13 and has a comb-tooth-shaped contact surface.

[0065] The first main body part 15 forms a comb-tooth-shaped contact surface through a plurality of convex parts 15a that extend in the direction of the inclined guiding part 13 and along the vertical direction when viewed from above. In the gas-liquid separation part As, a guiding wall 18 is formed between the protruding end part (the end part on the side opposite to the first main body part 15) of the second main body part 16 and the lower side wall 12a.

[0066] The separation space S is formed in the area divided by the first main body part 15, the second main body part 16, and the guiding wall 18 in the internal space of the lower housing 12. In addition, as Figure 9 shown, a first bulging part 19a is formed on the lower side wall 12a at a position in the lower housing 12 close to the end part of the first main body part 15 (the end part on the side opposite to the second main body part 16).

[0067] As Figure 9As shown, in the lower housing 12, an auxiliary collision wall 21 is arranged in the clockwise flow direction of the water-containing gas, and a second bulging portion 19b bulging toward the inside of the housing 10 is formed on the downstream side of the auxiliary collision wall 21. Further, a protruding wall 20 protruding toward the inside of the housing 10 is formed from the second bulging portion 19b.

[0068] The auxiliary collision wall 21 is arranged in a positional relationship where the lower end portion protrudes into the internal space of the lower housing 12. The auxiliary collision wall 21 protrudes toward the upstream side in the flow direction of the water-containing gas at the central position in the width direction in plan view, and protrusions 21a are formed at the central position and both end positions in the width direction.

[0069] 〔Flow of gas〕

[0070] In the gas-liquid separation portion As of this other embodiment (a), the water-containing gas from the inlet 1 is guided by the inclined guiding portion 13, collides with the first main body portion 15 in the separation space S, causes the separated water to fall onto the inner surface of the bottom wall 12b of the lower housing 12, guides the water from the bottom wall 12b to the water storage portion At, and stores it in the water storage space T.

[0071] In addition, the water-containing gas that has passed through the gas-liquid separation portion As passes through the main void Cm after water separation, and thus, as Figure 9 shown by the arrow in the figure, it swirls clockwise along the inner surface (side wall) of the housing 10 in plan view. Then, by moving along the inner wall of the housing 10 (the inner wall portion covering the upper side wall 11a and the lower side wall 12a), it reaches the auxiliary collision wall 21.

[0072] The water-containing gas contains a small amount of water. By colliding with the auxiliary collision wall 21, the water is separated, and the separated water falls onto the inner surface of the bottom wall 12b of the lower housing 12 and is stored in the water storage portion At. In addition, the dehydrated gas and the like after water separation are discharged to the outside from the discharge port 2.

[0073] In this way, when the water-containing gas conveyed obliquely upward from the inclined guiding portion 13 rises along the separation space S in the gas-liquid separation portion As of the other embodiment (a), water separation is achieved by bringing the water-containing gas into contact with the surfaces of the plurality of convex portions 15a. Since the gas-liquid separation portion As is structured to convey the water-containing gas upward and separate water in this manner when the water-containing gas flows upward, compared with a structure that uses a longitudinal gas flow path and generates a vortex in the upper part of the housing and contacts a plurality of separation vanes and the like to achieve water separation, a reduction in pressure loss is achieved.

[0074] (b) As described in the above embodiment, convex portions 15a are formed on the second main body portion 16. In addition, in this other embodiment (b), convex portions may be formed on the first main body portion 15 and the second main body portion 16 respectively to achieve good water separation.

[0075] (c) In the case of using a plurality of convex portions 15a of the comb-shaped contact surface constituting the gas-liquid separation portion As, a part of the convex portions 15a may be in an inclined posture, or the surface may be processed into a rough surface.

[0076] In addition, the structures disclosed in the above-described embodiments (including another embodiment, the same applies hereinafter) can be used in combination with the structures disclosed in other embodiments as long as there is no contradiction. In addition, the embodiments disclosed in this specification are merely examples, and the embodiments of the present utility model are not limited thereto, and can be appropriately changed without departing from the purpose of the present utility model.

[0077] In the above-described embodiment, the following structure is considered. (1) It has: a housing 10 having a water storage space T on the lower side; an inlet 1 connected to the housing 10 and introducing a water-containing gas; an inclined guiding portion 13 guiding the water-containing gas supplied from the inlet 1 into the interior of the housing 10 to a position above the water storage space T; and a separation plate P having a comb-shaped contact surface, and separating the water contained in the water-containing gas by bringing the water-containing gas guided by the inclined guiding portion 13 into contact with the contact surface.

[0078] According to this structure, the water-containing gas introduced into the interior of the housing 10 from the inlet 1 is guided by the inclined guiding portion 13 to a position above the water storage space T, and the water is separated by contacting the comb-shaped contact surface of the separation plate P. For example, this separation structure does not require a space for swirling the water-containing gas as a vortex, a plurality of blade-shaped members contacted by the vortex, and a flow path (separately provided flow path member) for allowing the gas to flow longitudinally, and can perform good water separation.

[0079] (2) In the gas-liquid separator A of (1), preferably, discharge spaces (first gap C1, second gap C2) from which the water-containing gas in contact with the separation plate P flows out are formed on both sides of the separation plate P.

[0080] Thereby, after the water-containing gas in contact with the separation plate P separates water by contacting the separation plate P, it flows through the discharge spaces (first gap C1, second gap C2) on both sides of the separation plate P, and is discharged to the outside of the housing 10, for example, in a state where an abnormal situation of short-circuit discharge without contacting the separation plate P is suppressed.

[0081] (3) In the gas-liquid separator A of (2), preferably, the separation plate P has: a main body portion (first main body portion 15, second main body portion 16) that protrudes from the upper inner surface of the housing 10 toward the water storage space T so as to surround the inclined guiding portion 13; and a plurality of convex portions 15a that extend from the main body portion toward the inclined guiding portion 13 and are along the vertical direction. On the upper inner surface of the housing 10, a collision plate 17 that collides with the water-containing gas flowing out into the discharge space extends from the separation plate P.

[0082] Thereby, the water-containing gas conveyed upward inside the housing 10 by the inclined guiding portion 13 comes into contact with the plurality of convex portions 15a that extend from the main body portion (first main body portion 15, second main body portion 16) of the separation plate P in the direction of the inclined guiding portion 13, so that water is separated. In addition, the water-containing gas flowing toward the upper inner surface of the housing 10 is separated from water by colliding with the collision plate 17 when flowing toward the discharge space, and the water separation performance can be maintained relatively high.

[0083] (4) In the gas-liquid separator A according to any one of (1) to (3), preferably, a gap G is formed between the inner surface of the housing 10 where the inlet 1 is formed and the inclined guiding portion 13, and a recovery flow path 5 having an inclined posture for allowing the water inside the gap G to flow toward the water storage space T.

[0084] Thereby, for example, when water-containing gas flows from the inner space of the housing 10 toward the inlet 1, the portion where the water-containing gas inside the housing 10 flows into the gap G is passed through, thereby suppressing the phenomenon of backflow toward the inlet 1. In addition, even when there is water inside the gap G, the water can flow from the recovery flow path 5 toward the water storage space T.

[0086] The utility model can be applied to a gas-liquid separator.
