Abstract
Description
Technical Field
[0001] This utility model generally relates to the technical field of electrolytic hydrogen production, and more specifically to a gas purification device and a containerized hydrogen production system. Background Technology
[0002] Currently, the hydrogen produced from the electrolyzers in water electrolysis for hydrogen production contains trace amounts of oxygen (0.1%-2%) and saturated water vapor, requiring further deoxygenation and drying purification to meet downstream gas requirements.

[0067] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.
[0068] This invention provides a gas purification device.
[0069] Please see Figure 1The gas purification device 100 includes an outer cylinder 110 and an inner cylinder 120, with the inner cylinder 120 connected to the outer cylinder 110.

The end of the inner cylinder 120 located inside the outer cylinder 110 has a second opening 121. Specifically, the inner cavity of the outer cylinder 110 and the inner cylinder 120 enclose a packing region 103, which includes a deoxidation region 132 and a drying region 112. The drying region 112 is used to fill a desiccant 113. The deoxidation region 132 is used to fill a deoxidizer 133. The deoxidation region 132 is provided with a plurality of first through holes 131 communicating between the interior of the deoxidation region 132 and the drying region 112.

[0070] According to the gas purification device 100 of this scheme, the functions of deoxygenation and drying are integrated into the same gas purification device. Compared with the traditional setting method of setting up deoxygenation tower and drying tower separately and connected in series, the volume of gas purification device and pipeline connection can be reduced.
[0071] Please continue reading. Figure 1 The outer cylinder 110 has a first opening 111 communicating with the outside and the interior of the outer cylinder 110. The inner cylinder 120 is connected to the first opening 111 and extends partially into the interior of the outer cylinder 110. The inner cylinder 120 is arranged in a vertical direction DH. The inner cylinder 120 is located above the bottom surface of the interior of the outer cylinder 110, and the inner cylinder 120 has at least one second opening 121 communicating with the interior of the outer cylinder 110 and the interior of the inner cylinder 120.
[0072] Furthermore, the gas purification device 100 also includes a containment member 130 and / or a barrier member 140. Figure 1 In this gas purification device 100, a containment member 130 and a blocking member 140 are included. Specifically, the containment member 130 is disposed inside the outer cylinder 110 and above the second opening 121, and is connected to the outer cylinder 110 and / or the inner cylinder 120. The containment member 130, together with the outer cylinder 110 and / or the inner cylinder 120, forms a deoxygenation zone 132. The containment member 130 is provided with a plurality of first through holes 131. The blocking member 140 is disposed inside the outer cylinder 110 and above the second opening 121. The blocking member 140 is connected to the outer cylinder 110 and the inner cylinder 120. The blocking member 140, the outer cylinder 110, and the inner cylinder 120 together form the aforementioned packing zone 103. The blocking member 140 is provided with at least one second through hole 141. It is understood that both the first through hole 131 and the second through hole 141 are used for the passage of gas (or gas mixture).
[0073] Preferably, please continue reading. Figure 1 The containment member 130 is connected to the outer cylinder 110, for example, the containment member 130 is connected to the inner wall surface of the outer cylinder 110. The containment member 130 is spaced apart from the outer peripheral surface of the inner cylinder 120 to form a channel 104. In an embodiment not shown, the containment member 130 may be connected to both the inner wall surface of the outer cylinder 110 and the outer peripheral surface of the inner cylinder 120; or, the containment member 130 may be connected to the outer peripheral surface of the inner cylinder 120 and spaced apart from the inner wall surface of the outer cylinder 110. The description here is based solely on the illustrated embodiment. The channel 104 connects to the drying zones 112 located at both ends of the deoxidation zone 132 along the height direction DH. The channel 104 is used to fill the desiccant 113. The containment member 130 is located in the middle of the outer cylinder 110. The blocking member 140 is located below the containment member 130. Specifically, the blocking member 140 is connected to both the inner wall surface of the outer cylinder 110 and the outer peripheral surface of the inner cylinder 120. It should be noted that the enclosure member 130 and the inner wall of the outer cylinder 110 enclose a deoxidation zone 132 for filling with deoxidizing agent 133. The inner wall of the inner cylinder 120, the outer cylinder 110, the enclosure member 130 and the barrier member 140 enclose a drying zone 112 for filling with desiccant 113.
[0074] Preferably, at least one first through-hole 131 is located at the top of the enclosure member 130, and at least one first through-hole 131 is located at the bottom of the enclosure member 130. In other words, the gas (or gas mixture) to be deoxidized enters the deoxidation zone 132 through the first through-hole 131 at the top and exits the deoxidation zone 132 through the first through-hole 131 at the bottom, thereby allowing the gas to have sufficient contact with the deoxidizing agent 133. Both the top and bottom of the enclosure member 130 can be constructed as porous partition structures. Correspondingly, the barrier member 140 can also be constructed as a porous partition structure.
[0075] Please continue reading. Figure 1The outer cylinder 110 is provided with a first inlet / outlet 115a communicating with the outside and the interior of the outer cylinder 110. The inner cylinder 120 is provided with a second inlet / outlet 122a communicating with the outside and the interior of the inner cylinder 120. The second inlet / outlet 122a is located outside the outer cylinder 110. Further, a portion of the inner cylinder 120 is located outside the outer cylinder 110 and protrudes upwards from the outer cylinder 110, and the second inlet / outlet 122a is located on the outer periphery of the inner cylinder 120. Specifically, the outer cylinder 110 is provided with a first inlet / outlet pipe 115, which connects to the upper part of the outer cylinder 110 and communicates with the interior of the outer cylinder 110. The first inlet / outlet pipe 115 is provided with a first inlet / outlet 115a communicating with the outside and the interior of the outer cylinder 110. The inner cylinder 120 is provided with a second inlet / outlet pipe 122, which is located on the outer periphery of the inner cylinder 120 and above the outer cylinder 110. The second inlet / outlet pipe 122 is connected to the inner cylinder 120 and communicates with the interior of the inner cylinder 120. The second inlet / outlet pipe 122 is provided with a second inlet / outlet 122a that communicates with the outside and the interior of the inner cylinder 120. The aforementioned second opening 121 is located at the bottom of the inner cylinder 120, and the second opening 121 communicates with the outside and the interior of the outer cylinder 110 via the second inlet / outlet 122a. A heating element 123 is provided inside the inner cylinder 120, and the heating element 123 is connected to the inner cylinder 120 and located above the second opening 121.
[0076] The following describes the filling and unloading of desiccant 113 and deoxidizer 133.
[0077] Please see now Figure 1The outer cylinder 110 is provided with a first feed inlet 116a and a first discharge outlet 117a. The first feed inlet 116a connects to the outside and the drying zone 112, and the first discharge outlet 117a connects to the outside and the drying zone 112. The first feed inlet 116a is located above the first discharge outlet 117a. Specifically, an inclined first feed pipe 116 is provided at the upper part of the outer cylinder 110. The first feed pipe 116 is connected to the outer cylinder 110 and communicates with the interior of the outer cylinder 110 (the drying zone 112). The first feed pipe 116 is provided with a first feed inlet 116a connecting the outside and the interior of the outer cylinder 110. Furthermore, an inclined first discharge pipe 117 is also provided on the outer periphery of the outer cylinder 110. The first discharge pipe 117 is connected to the outer cylinder 110 and communicates with the interior of the outer cylinder 110. The first discharge pipe 117 is located below the first feed pipe 116. The first discharge pipe 117 is provided with a first discharge port 117a connecting the outside and the interior (drying zone 112) of the outer cylinder 110. It is understood that both the first inlet 116a and the first discharge port 117a are designed to be openable and closable to facilitate the filling and discharge of the desiccant 113. For example, when desiccant 113 is added to the drying zone 112 through the first inlet 116a, the desiccant 113 falls into the interior of the outer cylinder 110 and then through the gap between the confining member 130 and the inner cylinder 120 to the blocking member 140, gradually accumulating in the drying zone 112 until it is completely filled. When the first discharge port 117a is opened, the desiccant 113 in the drying zone 112 can fall to the outside through the first discharge port 117a until all the desiccant 113 in the drying zone 112 is discharged.
[0078] Please continue reading. Figure 1The outer cylinder 110 is also provided with a second feed inlet 118a and a second discharge outlet 119a. The second feed inlet 118a connects to the outside and the deoxidation zone 132, and the second discharge outlet 119a connects to the outside and the deoxidation zone 132. The second feed inlet 118a is located above the second discharge outlet 119a. Specifically, an inclined second feed pipe 118 is provided on the outer periphery of the outer cylinder 110, connecting to the outer cylinder 110 and communicating with the interior of the outer cylinder 110 (the deoxidation zone 132). The second feed pipe 118 has a second feed inlet 118a connecting to the outside and the interior of the outer cylinder 110. Furthermore, an inclined second discharge pipe 119 is also provided on the outer periphery of the outer cylinder 110, connecting to the outer cylinder 110 and communicating with the interior of the outer cylinder 110. The second discharge pipe 119 is located below the second feed pipe 118. The second discharge pipe 119 is provided with a second discharge port 119a connecting the outside and the inside of the outer cylinder 110 (the deoxidation zone 132). It is understood that both the second inlet 118a and the second discharge port 119a are designed to be openable and closable to facilitate the filling and discharge of the deoxidizer 133. For example, deoxidizer 133 is fed into the deoxidation zone 132 through the second inlet 118a. After falling into the inside of the outer cylinder 110, the deoxidizer 133 accumulates at the bottom of the containment member 130 and gradually piles up in the deoxidation zone 132 until it is completely filled. When the second discharge port 119a is opened, the deoxidizer 133 in the deoxidation zone 132 can fall to the outside through the second discharge port 119a until the deoxidizer 133 in the deoxidation zone 132 is completely discharged.
[0079] It should be noted that, horizontally, the first feed pipe 116 and the first discharge pipe 117 are located on the same side of the outer cylinder 110. The inlet end of the first feed pipe 116 (i.e., the location where the first feed port 116a is provided) is inclined upward relative to the outer cylinder 110, and the outlet end of the first discharge pipe 117 (i.e., the location where the first discharge port 117a is provided) is inclined downward relative to the outer cylinder 110. Furthermore, horizontally, the second feed pipe 118 and the second discharge pipe 119 are located on opposite sides of the outer cylinder 110. Vertically, in the direction DH, the second feed pipe 118 is located below the first inlet / outlet pipe 115, the second discharge pipe 119 is located between the first feed pipe 116 and the first discharge pipe 117, and the first feed pipe 116 is located below the second inlet / outlet pipe 112. The inlet end of the second feed pipe 118 (i.e., the location where the second feed port 118a is provided) is inclined upward relative to the outer cylinder 110, and the outlet end of the second discharge pipe 119 (i.e., the location where the second discharge port 119a is provided) is inclined downward relative to the outer cylinder 110. Furthermore, the second feed pipe 118 and the first inlet / outlet pipe 115 are located on the same side of the outer cylinder 110. The first feed pipe 116, the first discharge pipe 117, and the second discharge pipe 119 are also located on the same side of the outer cylinder 110.
[0080] The gas purification apparatus 100 also includes a first temperature monitoring component 101 and / or a second temperature monitoring component 102. Specifically, the first temperature monitoring component 101 is disposed in the outer cylinder 110 and extends at least partially into the drying zone 112. The second temperature monitoring component 102 is disposed in the outer cylinder 110 and extends at least partially into the deoxygenation zone 132. Figure 1 In the gas purification device 100, a first temperature monitoring component 101 and a second temperature monitoring component 102 are included. Furthermore, the number of first temperature monitoring components 101 is at least two; wherein at least one first temperature monitoring component 101 is located above the deoxygenation zone 132, and at least one first temperature monitoring component 101 is located below the deoxygenation zone 132. For example... Figure 1 In this configuration, there are two first temperature monitoring components 101 and one second temperature monitoring component 102. One first temperature monitoring component 101 is located above the deoxidation zone 132, and the other first temperature monitoring component 101 is located below the deoxidation zone 132. Both the first temperature monitoring component 101 and the second temperature monitoring component 102 can be constructed as temperature-sensing elements incorporating platinum resistance thermometers. It is understood that the first temperature monitoring component 101 is used to monitor the temperature of the desiccant 113, and the second temperature monitoring component 102 is used to monitor the temperature of the deoxidizer 133.
[0081] Please continue reading. Figure 1 The outer cylinder 110 is also provided with a discharge port 114, which connects the outside to the inside of the outer cylinder 110 and is located below the inner cylinder 120. The function of the discharge port 114 will be described below. Furthermore, the gas purification device 100 also includes a base 150, which is located below and connected to the outer cylinder 110. It can be understood that the base 150 is provided to facilitate the placement of the gas purification device 100.
[0082] The following describes the gas purification process performed by the gas purification device 100.
[0083] The following explanation uses hydrogen obtained from water electrolysis as an example. Those skilled in the art will know that hydrogen obtained from water electrolysis typically contains trace amounts of oxygen (generally between 0.1% and 2%) and saturated water vapor, thus requiring deoxygenation and drying processes.
[0084] Please see now Figure 1 , Figure 1 The direction of gas flow is shown when the gas purification device 100 is in operation (see...). Figure 1(Indicated by the arrows in the diagram). When the gas purification device 100 is operating normally, hydrogen enters the outer cylinder 110 from the first inlet / outlet 115a, flowing sequentially through the drying zone 112 (upper part of the outer cylinder 110), the deoxygenation zone 132 (middle part of the outer cylinder 110), and the lower part of the outer cylinder 110. After being adsorbed by the desiccant 113 and deoxygenator 133, the hydrogen flows through the second through-hole 141 into the inner cylinder 120. At this time, the heating element 123 inside the inner cylinder 120 is not working, and the hydrogen finally flows from the inner cylinder 120 to the second inlet / outlet 122a and is discharged. When the adsorption working time reaches the predetermined working time of the gas purification device 100, the desiccant 113 and deoxygenator 133 inside the outer cylinder 110 no longer have good adsorption capacity. At this time, it is necessary to switch the direction of hydrogen flow.
[0085] Please see now Figure 2 , Figure 2 The flow direction of gas in the regeneration state of the gas purification device 100 is shown (see...). Figure 2 (As indicated by the arrow in the diagram). Hydrogen gas enters the inner cylinder 120 through the second inlet / outlet 122a, and the heating element 123 is activated to heat the hydrogen gas. The high-temperature hydrogen gas flows from top to bottom to the bottom of the outer cylinder 110, and then passes through the second through-hole 141 into the drying zone 112 (lower part of the outer cylinder 110), the deoxygenation zone 132 (middle part of the outer cylinder 110), and the drying zone 112 (upper part of the outer cylinder 110), carrying away the moisture attached to the desiccant 113 and the deoxygenator 133. Finally, it flows from the outer cylinder 110 to the first inlet / outlet 115a and is discharged, thus regenerating the gas purification device 100. After prolonged use, some contaminants may accumulate inside the gas purification device 100. The discharge port 114 can discharge the accumulated contaminants from the gas purification device 100.
[0086] According to this utility model, the gas purification device integrates deoxygenation and drying functions into a single gas purification unit, reducing the overall size of the device and the number of pipeline connections. This gas purification device can simultaneously regenerate the deoxygenator and desiccant through hot gas flow circulation. The entire device is energy-efficient, simple to control, compact in structure, and occupies a small area, making it suitable for containerized hydrogen production equipment.
[0087] Based on this, the present invention also provides a containerized hydrogen production system.
[0088] Specifically, the containerized hydrogen production system includes a container (not shown) and the aforementioned gas purification device 100, which is located inside the container.
