Technical Field

[0002] The existing hydrogen production system includes a hydrogen production device, a gas-liquid separator and a power generation device. The power generation device generates electricity by wind power and provides electric energy for the hydrogen production device. The gas-liquid separator is used to separate gaseous hydrogen and liquid components from the gas-liquid two-phase mixture output by the hydrogen production device.

[0003] However, due to the large variation in wind speed, the power output by the power generation device is unstable. Thus, the volume of the gas-liquid two-phase mixture output by the hydrogen production device per unit time is also unstable. As a result, the fluctuation of the liquid in the gas-liquid separator is relatively large, and the safety of the gas-liquid separator is low.

[0004] Therefore, the utility model provides a gas-liquid separator and a hydrogen production system to at least partially solve the above problems. Summary of the Utility Model

[0044] The preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are for illustrative purposes only and not for limitation.

[0045] In this article, the ordinal numbers such as "first" and "second" cited in the present utility model are only identifiers and do not have any other meanings, such as a specific order, etc.

[0046] In order to thoroughly understand the embodiments of the present utility model, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present utility model is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present utility model are described in detail below. However, in addition to these detailed descriptions, the present utility model can also have other embodiments.

[0047] The present utility model provides a gas-liquid separator. A plurality of liquid stabilizing members 120 are provided in the housing 110 of the gas-liquid separator to weaken the fluctuation of the liquid in the gas-liquid separator. The gas-liquid separator can be used in a hydrogen production system powered by a power device through wind power generation to separate gaseous hydrogen and liquid components.

[0048] Please refer to Figures 1 to 6, the gas-liquid separator includes a housing 110. The interior of the housing 110 has a receiving space 111, an inlet 112, a liquid outlet 113, and a gas outlet 114. The inlet 112, the liquid outlet 113, and the gas outlet 114 are spaced apart from each other in pairs. The inlet 112, the liquid outlet 113, and the gas outlet 114 are all connected to the receiving space 111. Among them, the gas outlet 114 is located at the top end of the housing 110. The liquid outlet 113 is located at the bottom end of the housing 110.

[0049] Thus, please refer to Figure 2 , the gas-liquid two-phase mixture (fluid) enters the receiving space 111 of the housing 110 through the inlet 112. The gas-liquid two-phase mixture is separated into gas and liquid in the receiving space 111. The liquid component forms a liquid and flows downward to the bottom end of the receiving space 111, and is discharged from the housing 110 through the liquid outlet 113. The gaseous hydrogen flows upward to the top end of the receiving space 111 and is discharged from the housing 110 through the gas outlet 114.

[0050] Among them, along the first horizontal direction D1, the liquid flows from one end of the receiving space 111 to the other end in the receiving space 111.

[0051] As Figure 2 shown, along the first horizontal direction D1, the inlet 112 is located at one end of the housing 110. The gas outlet 114 and the inlet are located near the other end of the housing 110. In this way, the gas-liquid separation effect can be increased as much as possible.

[0052] Optionally, the housing 110 is a cylindrical tank. The axial direction of the housing 110 is parallel to the first horizontal direction D1. Thus, the housing 110 has a horizontal structure and a small height dimension.

[0053] As Figures 2 to 6 shown, there are at least two liquid stabilizing members 120. The liquid stabilizing members 120 are located in the receiving space 111. The liquid stabilizing members 120 are partially connected to the inner wall surface of the housing 110 to form a channel 130 that penetrates along the first horizontal direction D1.

[0054] At least two liquid stabilizing members 120 are arranged at intervals in sequence along the first horizontal direction D1. The projections of at least two channels 130 in the first horizontal direction D1 (the projection plane of this projection is perpendicular to the first horizontal direction D1) are at least partially staggered along the second horizontal direction D2.

[0055] Specifically, for example, two liquid stabilizing members 120 arranged at intervals along the first horizontal direction D1 are at least partially staggered along the second horizontal direction D2. In this way, the projections of at least two channels 130 in the first horizontal direction D1 are at least partially staggered along the second horizontal direction D2. Liquid (an example of a fluid) flows through the liquid stabilizing member 120 via the channel 130. The liquid stabilizing member 120 can slow down the flow rate of the liquid, thereby stabilizing the liquid and weakening the fluctuation of the liquid. The first horizontal direction D1 and the second horizontal direction D2 intersect. For example, they are perpendicular.

[0056] It can be understood that in some cases, the channel 130 can allow liquid and gas to pass through.

[0057] The arrangement in which the projections of at least two channels 130 in the first horizontal direction D1 are at least partially staggered along the second horizontal direction D2 can change the flow direction of the liquid, thereby further slowing down the flow rate of the liquid and further stabilizing the liquid.

[0058] Optionally, as Figure 2 shown, the liquid stabilizing member 120 is connected to the bottom end of the inner wall surface 115 of the housing 110. Thus, the liquid stabilizing member 120 can contact the liquid as much as possible, enhancing the effect of slowing down the flow rate of the liquid.

[0059] In this embodiment, the liquid stabilizing member 120 is partially connected to the inner wall surface 115 of the housing 110 to form the channel 130. In this way, the liquid flows through the liquid stabilizing member 120 via the channel 130. The arrangement of multiple liquid stabilizing members 120 can slow down the flow rate of the liquid, thereby stabilizing the liquid and weakening the fluctuation of the liquid. The arrangement in which the projections of at least two channels 130 in the first horizontal direction D1 are at least partially staggered along the second horizontal direction D2 can change the flow direction of the liquid, thereby further slowing down the flow rate of the liquid and further stabilizing the liquid. The gas-liquid separator has high safety and strong stability.

[0060] Optionally, as Figures 2 to 6 shown, the liquid stabilizing member 120 has a blocking portion 121. The blocking portion 121 can be a plate-like structure. The plane where the blocking portion 121 is located is perpendicular to the first horizontal direction. The blocking portion 121 has an edge 124. The edge 124 is located at one end of the blocking portion 121 along the second horizontal direction D2. The other end of the blocking portion 121 away from the edge 124 is connected to the inner wall surface 115. The bottom end of the blocking portion 121 (an example of the bottom end of the liquid stabilizing member 120) is connected to the bottom end of the inner wall surface 115.

[0061] Along the second horizontal direction D2, there is a first predetermined distance between the edge 124 and the other end of the inner wall surface 115 along the second horizontal direction D2. In this way, the blocking portion 121 forms a first notch 125 at the edge 124. Thus, the blocking portion 121 and the inner wall surface 115 form a channel 130 at the first notch 125. Therefore, there is no need to provide a hole in the blocking portion 121 to form the channel 130, and the structure of the liquid stabilizing member 120 is simple. The first predetermined distance can be set as needed.

[0062] It can be understood that in an embodiment not shown, both ends of the blocking portion along the second horizontal direction D2 can form the first notch. Or the blocking portion is provided with a through hole to form the channel.

[0063] Further, as Figures 2 to 6 shown, along the second horizontal direction D2, the edge 124 and the first perpendicular bisector 116 of the housing 110 are spaced apart. Along the second horizontal direction D2, the edge 124 is located on one side of the first perpendicular bisector 116. Thus, the liquid can be more effectively stabilized. The first perpendicular bisector 116 extends in the vertical direction. The first perpendicular bisector 116 extends through the center of the accommodation space 111 along the second horizontal direction D2.

[0064] Further, as Figures 2 to 6 shown, along the second horizontal direction D2, the distance between the edge 124 and the first perpendicular bisector 116 of the housing 110 ranges from 230 mm to 260 mm. For example, 250 mm. Thus, the liquid can be more effectively stabilized.

[0065] Further, as Figures 2 to 6 shown, along the second horizontal direction D2, the maximum dimension of the blocking portion 121 is greater than half of the maximum dimension of the accommodation space 111. The dimension of the uppermost end of the blocking portion 121 along the second horizontal direction D2 is the maximum dimension of the blocking portion 121 along the second horizontal direction D2. In this way, along the second horizontal direction D2, the blocking portion 121 extends through the first perpendicular bisector 116 of the housing 110. Therefore, the strength of the blocking portion 121 is high.

[0066] Further, as Figures 2 to 6 shown, the edge 124 extends in the vertical direction. Thus, the structure of the liquid stabilizing member 120 is simple.

[0067] Optionally, as Figures 2 to 6 shown, in the vertical direction, the top of the liquid stabilizing member 120 is spaced apart from the top of the accommodation space 111 by a second predetermined distance. Along the vertical direction, the maximum dimension of the liquid stabilizing member 120 is greater than half of the maximum dimension of the accommodation space 111. The dimension of the liquid stabilizing member 120 along the vertical direction at the middle position along the second horizontal direction D2 is the maximum dimension of the liquid stabilizing member 120 along the vertical direction.

[0068] In this way, the liquid stabilizing member 120 extends through the second vertical median line 117 of the accommodating space 111. The upper surface of the liquid stabilizing member 120 is located above the second vertical median line of the accommodating space 111. Thus, the gap between the top of the liquid stabilizing member 120 and the top of the accommodating space 111 allows gas to pass through. In addition, the volume of the liquid stabilizing member 120 can be reduced, saving costs.

[0069] In the vertical direction, the setting that the maximum dimension of the liquid stabilizing member 120 is greater than half of the maximum dimension of the accommodating space 111 can block the liquid as much as possible, preventing the liquid from passing over the liquid stabilizing member 120 from above, and thus stabilizing the liquid more effectively. The second median line 117 extends along the second horizontal direction D2. The second median line 117 extends through the vertical center of the accommodating space 111.

[0070] As Figures 2 to 6 shown, the liquid stabilizing member 120 has a reinforcing portion 122. The reinforcing portion 122 is a strip structure. The length direction of the reinforcing portion 122 extends along the second horizontal direction D2. The reinforcing portion 122 is connected to the top end of the blocking portion 121. The reinforcing portion 122 is located above the second vertical median line 117 of the housing 110. Both ends of the reinforcing portion 122 along the second horizontal direction D2 are connected to the inner wall surface 115. Thus, the lower end and the edge 124 of the reinforcing portion 122 form a first notch 125. Thereby, the liquid stabilizing member 120 has high strength.

[0071] As Figure 2 、 Figure 5 and Figure 6 shown, the cross-section of the reinforcing portion 122 (the cross-section is perpendicular to the second horizontal direction D2) includes a first wall 126 and a second wall 127. The second wall 127 is located below the first wall 126 and is connected to the first wall 126. The lower end of the second wall 127 is connected to the blocking portion 121. Thereby, the reinforcing portion 122 has high strength.

[0072] Furthermore, the second wall 127 and the first wall 126 form a T-shaped structure. Thereby, the structure of the reinforcing portion 122 is simple.

[0073] Furthermore, the range of the distance between the upper surface of the liquid stabilizing member 120 and the second vertical median line 117 of the housing 110 is 110 mm to 140 mm. For example, 125 mm. Thus, the liquid can be stabilized more effectively.

[0074] Furthermore, the range of the dimension of the reinforcing portion 122 in the vertical direction is 70 mm to 90 mm. For example, 80 mm. Thereby, the reinforcing portion 122 has high strength.

[0075] Optionally, a second notch 131 penetrating along the first horizontal direction D1 is formed at the bottom end of the blocking portion 121 close to the inner wall surface of the housing 110. The second notch 131 and the bottom end of the inner wall surface form a bottom channel. In this way, the liquid at the bottom of the accommodation space 111 can flow through the bottom channel, thereby draining the liquid in the housing 110 as completely as possible.

[0076] Furthermore, the second notch 131 may be a V-shaped structure. Thus, the structure of the second notch 131 is simple. It can be understood that in an embodiment not shown, the second notch may be a U-shaped structure or other structures.

[0077] Optionally, please refer to Figures 2 to 6 , the projections of any two adjacent channels 130 along the first horizontal direction D1 in the first horizontal direction D1 are at least partially staggered along the second horizontal direction D2. Specifically, the liquid stabilizing member 120 includes a first liquid stabilizing member 128 and a second liquid stabilizing member 129. The first liquid stabilizing member 128 and the second liquid stabilizing member 129 are adjacent along the first horizontal direction D1.

[0078] Along the second horizontal direction D2, the edge 124 of the first liquid stabilizing member 128 is located at the first end of its blocking portion 121 close to the first side of the housing 110. Along the second horizontal direction D2, the edge 124 of the second liquid stabilizing member 129 is located at the second end of its blocking portion 121 close to the second side of the housing 110. Along the second horizontal direction D2, the first side and the second side of the housing 110 are arranged back to back. Thus, the liquid can be stabilized more effectively.

[0079] Along the first horizontal direction D1, at least two liquid stabilizing members 120 are arranged staggeredly. Specifically, along the first horizontal direction D1, the first liquid stabilizing member 128, the second liquid stabilizing member 129, the first liquid stabilizing member 128, the second liquid stabilizing member 129 and the first liquid stabilizing member 128 are arranged in sequence. Thus, the liquid can be stabilized more effectively.

[0080] As Figure 2 shown, along the first horizontal direction D1, any one liquid stabilizing member 120 is located between the inlet 112 and the air outlet 114. Thus, the gas can be discharged as much as possible.

[0081] Along the first horizontal direction D1, the liquid stabilizing member 120 is located between the inlet 112 and the liquid outlet 113 with the maximum distance from the inlet 112. Part of the liquid outlets 113 are located between two adjacent liquid stabilizing members 120 along the first horizontal direction D1. In this way, at least part of the liquid stabilizing members 120 are located between the inlet 112 and the liquid outlet 113. Thus, the liquid can be discharged as much as possible.

[0082] This embodiment also provides a hydrogen production system. The hydrogen production system includes the aforementioned gas-liquid separator. The gas-liquid separator is used to separate gaseous hydrogen and liquid components in the hydrogen production system.

[0083] It can be understood that in an embodiment not shown, the gas-liquid separator can also be used in other devices or systems with gas-liquid separation requirements.

[0084] In this embodiment, the hydrogen production system includes the aforementioned gas-liquid separator. The liquid stabilizing member 120 is partially connected to the inner wall surface 115 of the housing 110 to form a channel 130. In this way, the liquid flows through the liquid stabilizing member 120 via the channel 130. The arrangement of multiple liquid stabilizing members 120 can slow down the flow rate of the liquid, thereby stabilizing the liquid and weakening the fluctuation of the liquid. The arrangement that at least two channels 130 are at least partially staggered in the projection along the second horizontal direction D2 in the first horizontal direction D1 can change the flow direction of the liquid, thereby further slowing down the flow rate of the liquid, further stabilizing the liquid, and the gas-liquid separator has high safety and strong stability.
