Since the 1940s, fuel cells have developed to the fourth generation. The first generation includes alkaline fuel cells (AFC) and phosphoric acid fuel cells (PAFC), the second generation is molten carbonate fuel cells (MCFC), the third generation is solid oxide fuel cells (SOFC), and the fourth generation includes proton exchange membrane fuel cells (PEMFC) and direct methanol fuel cells. Among them, solid oxide fuel cells have a higher operating temperature, usually in the range of 800 to 1000°C. This feature allows it to generate electricity while also using waste heat to achieve combined heat and power, thereby achieving an energy utilization efficiency of up to 90%.

[0003] The operation of fuel cells requires the supply of fuel gas, and untreated fuel gas contains tetrahydrothiophene and hydrogen sulfide. These sulfur-containing components entering the fuel cell system will poison the fuel cell (react with the anode catalyst) and make it fail. Therefore, the fuel gas needs to be desulfurized before being supplied to the system. Currently, a single desulfurization device cannot adapt to desulfurizers of multiple specifications. When the specifications of the desulfurizer are changed, the desulfurization device needs to be replaced to adapt. Summary of the invention

[0049] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0050] like Figures 1 to 4 As shown, the present invention provides a desulfurization device for desulfurizing the fuel gas introduced into the fuel cell to prevent the sulfur-containing fuel gas from entering the fuel cell system and poisoning the fuel cell (reacting with the anode catalyst) to cause it to fail.

[0051] The desulfurization device comprises a tank body 1 and a desulfurization shunt assembly 2; the tank body 1 has a accommodating chamber 11, an air inlet 12 and an air outlet 13, the accommodating chamber 11 is used to provide a reaction space for desulfurization of sulfur-containing fuel gas, the air inlet 12 and the air outlet 13 are respectively arranged at both ends of the accommodating chamber 11, and the air inlet 12 is communicated with the accommodating chamber 11 to pass the fuel gas into the accommodating chamber 11 for desulfurization; the air outlet 13 is communicated with the accommodating chamber 11 to discharge the desulfurized fuel gas; the desulfurization shunt assembly 2 is arranged in the accommodating chamber 11, and divides the accommodating chamber 11 into a desulfurization area 111 communicated with the air outlet 13 and a buffer area 112 communicated with the air inlet 12;

[0052] Among them, the desulfurization diversion component 2 includes a first diversion piece 21 for diverting the gas flowing from the buffer area 112 to the desulfurization area 111, and a first filter 22 for preventing the first desulfurizer 10 from falling onto the first diversion piece 21 and / or the buffer area 112; the first filter 22 is detachably arranged in the accommodating cavity 11.

[0053] Based on the above structure, the fuel gas flows into the buffer area 112 through the air inlet 12, diffuses evenly in the buffer area 112, and enters the desulfurization area 111 filled with the first desulfurizer 10 after being diverted by the first diverter 21 for desulfurization, and then is discharged from the tank body 1 through the air outlet 13. The first filter 22 is located between the first desulfurizer 10 and the first diverter 21, separating the first desulfurizer 10 and the first diverter 21. On the one hand, the first filter 22 is used to prevent the first desulfurizer 10 from falling into the buffer area 112, thereby reducing the buffering effect of the fuel gas, and also prevents the first desulfurizer 10 from falling on the first diverter 21 to block the first diverter hole 212, thereby affecting the diversion effect of the fuel gas. On the other hand, through the detachable installation method, when the specifications of the first desulfurizer 10 to be used change, it is only necessary to replace the specifications of the first filter 22 to meet the use requirements without replacing the desulfurization device, which simplifies the operation and is conducive to large-scale production and use.

[0054] It should be noted that, in the present embodiment, there may be a gap between the first filter 22 and the first diverter 21, or the first filter 22 may be directly installed on the first diverter 21, and no special limitation is made here. When there is a gap between the first filter 22 and the first diverter 21, the first filter 22 and the tank body 1 have a detachable connection structure, such as a snap-on or plug-in method; when the first filter 22 is directly installed on the first diverter 21, the first filter 22 may be directly placed on the first diverter 21, or may have a detachable connection structure with the first diverter 21, such as a snap-on or plug-in method.

[0055] like Figure 4 As shown, in some embodiments, the tank body 1 includes a first cover body 14, a second cover body 15 and a first body 16, and the two ends of the first body 16 are respectively connected to the first cover body 14 and the second cover body 15 to enclose and form a receiving cavity 11. The first cover body 14 and the second cover body 15 are both concave toward the center to form a certain arc, so as to prevent stress concentration.

[0056] In this embodiment, the first cover 14 is disposed at the upper end of the first body 16, and the second cover 15 is disposed at the lower end of the first body 16. At this time, the fuel gas flows from bottom to top. Based on this, the first cover 14, the first body 16 and the first filter 22 enclose the desulfurization area 111, and the second cover 15, the first body 16 and the first diverter 21 enclose the buffer area 112. The second cover 15 is provided with an air inlet 12, and the first cover 14 is provided with an air outlet 13, so that the fuel gas is introduced from the lower end, and flows through the buffer area 112 and the desulfurization area 111 in sequence and then discharged from the upper end.

[0057] It can be understood that the first cover 14 in this embodiment can also be understood as being arranged at the lower end of the first body 16, and the second cover 15 being arranged at the upper end of the first body 16. At this time, the fuel gas flows from top to bottom, enters from the top, flows through the buffer area 112 and the desulfurization area 111 in sequence, and is discharged from the lower end. The positions of the first cover 14 and the second cover 15 are not particularly limited here, and the following is described by taking the example that the first cover 14 is arranged at the upper end of the first body 16 and the second cover 15 is arranged at the lower end of the first body 16.

[0058] The desulfurization device also includes a discharge portion 3, which is installed on the second cover body 15 and is connected to the accommodating chamber 11, so that when the first desulfurizer 10 needs to be replaced or the desulfurization device is under maintenance, the first desulfurizer 10 in the desulfurization area 111 can be discharged from the desulfurization tank body 1 through the discharge portion 3 due to gravity.

[0059] In addition, the desulfurization device also includes a packing part 4, which is installed on the first cover body 14, so that when the first desulfurizer 10 is added to the desulfurization device, the first desulfurizer 10 is fed from the upper end to the desulfurization area 111, so that after the first desulfurizer 10 falls into the desulfurization area 111 due to gravity, it will not hinder the subsequent feeding of the first desulfurizer 10.

[0060] In some embodiments, the discharge portion 3 includes a discharge pipe 31 for allowing the first desulfurizer 10 to be discharged therethrough, a first discharge hole 211 is provided on the first diverter 21, and a second discharge hole 221 connected to the first discharge hole 211 is provided on the first filter screen 22. It can be understood that the first discharge hole 211 and the second discharge hole 221 here can be connected directly or indirectly, such as the discharge pipe 31 is connected to the first diverter 21, and the first discharge hole 211 and the pipe mouth of the discharge pipe 31 are correspondingly arranged, and the first filter screen 22 is directly installed on the first diverter 21. At this time, the first discharge hole 211 and the second discharge hole 221 are directly connected, so that the first desulfurizer 10 directly flows into the discharge pipe 31 through the second discharge hole 221 and the first discharge hole 211 through the pipe mouth of the discharge pipe 31, and the final discharge of the first desulfurizer 10 is achieved. In addition, when there is a gap between the first filter screen 22 and the first diverter 21 , a pipeline connection may be provided between the first discharge hole 211 and the second discharge hole 221 .

[0061] In actual application, one end of the discharge pipe 31 is located inside the tank body 1 to connect with the first diverter 21, and the other end of the discharge pipe 31 passes through the second cover 15 and is exposed outside the tank body 1, so that the staff can collect the first desulfurizer 10. It can be understood that the discharge part 3 includes a first sealing cover 32, and the end of the discharge pipe 31 located outside the tank body 1 is connected to the first sealing cover 32, which is used to block the discharge pipe 31 to prevent the first desulfurizer 10 from being discharged along with the discharge pipe 31 during the reaction of the first desulfurizer 10, and also prevent the fuel gas from escaping from the discharge pipe 31. Specifically, when the first desulfurizer 10 needs to be replaced or the desulfurization device is overhauled, the first sealing cover 32 is opened, and the first desulfurizer 10 enters the discharge pipe 31 through the first discharge hole 211 opened on the first diverter 21, and is discharged from the desulfurization device through the discharge pipe 31.

[0062] The packing part 4 includes a packing pipe 41 and a second sealing cover 42. One end of the packing pipe 41 is located inside the tank body 1 so as to pass the first desulfurizer 10 into the desulfurization area 111; the other end of the packing pipe 41 is located outside the tank body 1 so as to allow the staff to pass the first desulfurizer 10. It can be understood that the end of the packing pipe 41 located outside the tank body 1 is connected to the second sealing cover 42, which is used to block the packing pipe 41 to prevent the fuel gas from being discharged along with the packing pipe 41 during the reaction of the first desulfurizer 10. Specifically, when packing is needed, the second sealing cover 42 is opened, and the first desulfurizer 10 is added to the desulfurization device, and the first desulfurizer 10 enters the desulfurization area 111 through the packing pipe 41.

[0063] In some embodiments, the central axis of the filler portion 4 forms an angle α (eg Figure 3 As shown), then α satisfies: 0°≤α≤90°.

[0064] In this embodiment, the angle α is preferably the angle formed between the central axis of the filling pipe 41 and the central axis of the tank body 1. When the desulfurization device is placed outdoors, it is necessary to prevent rainwater from entering the desulfurization device to cause the first desulfurizer 10 to fail, and at the same time, it is necessary to ensure that the first desulfurizer 10 can easily enter the tank body 1 through the filling pipe 41. Therefore, α in this embodiment is preferably 30-60°, such as 30°, 45°, 53° or 60°, which can effectively prevent rainwater from entering without affecting the filling of the desulfurizer.

[0065] like Figure 4 and Figure 5As shown, in some embodiments, the first flow divider 21 has a plurality of first flow diversion holes 212 for gas to pass through, a first end face 213 facing the first filter 22, and a second end face 214 arranged opposite to the first end face 213. The first flow diversion hole 212 is arranged through the first end face 213 and the second end face 214, so that the fuel gas in the buffer area 112 is dispersed through the plurality of first flow diversion holes 212 opened on the first flow diversion piece 21 and then enters the desulfurization area 111 uniformly, so as to prevent the fuel gas from being too concentrated, resulting in the desulfurization agent not being fully utilized when it passes through the desulfurization area 111. The above arrangement further improves the desulfurization effect of the fuel gas. Preferably, the first flow diversion piece 21 is a hollow conical structure, and the conical structure is used to guide the fuel gas to disperse upward along its taper, which is beneficial to the flow of the fuel gas.

[0066] In some embodiments, assuming that the total opening area of ​​the first diverter holes 212 is S1, and the area of ​​the first end surface 213 or the second end surface 214 of the first diverter member 21 is S2, then S1 / S2 satisfies 0.5-0.7.

[0067] In this embodiment, the fuel gas in the buffer area 112 flows into the desulfurization area 111 through the first diverter hole 212 opened on the first diverter 21. If S1 / S2 is less than 0.5, the opening area of ​​the first diverter hole 212 on the first diverter 21 is too small, and the flow resistance of the fuel gas in the buffer area 112 is relatively large when passing through the first diverter 21, and it is not easy for the fuel gas to enter the desulfurization area 111; if S1 / S2 is greater than 0.7, the opening area of ​​the first diverter hole 212 on the first diverter 21 is too large, which reduces the rigidity of the first diverter 21 and easily causes deformation of the first diverter 21.

[0068] like Figure 6 and Figure 7 As shown, in some embodiments, the first filter screen 22 is in contact with the first diverter 21, and the first filter screen 22 has a plurality of first filter holes 222 for gas to pass through, a third end face 223 facing the first diverter 21, and a fourth end face 224 arranged opposite to the third end face 223. The first filter hole 222 is arranged through the third end face 223 and the fourth end face 224. The first filter screen 22 can prevent the first desulfurizer 10 from falling into the buffer area 112, thereby preventing the first diverter hole 212 from being blocked, resulting in a reduction in the buffer effect of the fuel gas. When the desulfurization device needs to replace the first desulfurizer 10 of different specifications, it is only necessary to replace the first filter screen 22 of different specifications to adapt the first desulfurizer 10, without replacing the desulfurization device as a whole. Preferably, the first filter screen 22 is a hollow conical structure. The structure of the first filter screen 22 in this embodiment is similar to that of the first diverter 21, so as to facilitate the assembly of the two. The first filter screen 22 can also guide the fuel gas to disperse upward along its taper using the conical structure, which is conducive to the flow of the fuel gas.

[0069] It should be noted that the conical structure of the first filter screen 22 and the first diverter 21 in this embodiment also facilitates the first desulfurizer 10 to flow into the discharge pipe 31 along the guide of the taper during the subsequent unloading process.

[0070] In some embodiments, assuming that the particle diameter of the first desulfurizing agent 10 added to the desulfurization area 111 is R1, and the diameter of the first filter hole 222 is R2, then: R1>R2.

[0071] In this embodiment, the first filter screen 22 is used to prevent the first desulfurizer 10 from falling into the buffer area 112, thereby preventing the first diversion hole 212 from being blocked, resulting in a reduction in the fuel gas buffering effect. Therefore, the diameter of the first filter hole 222 opened on the first filter screen 22 is smaller than the particle diameter of the first desulfurizer 10.

[0072] like Figure 8 and Fig. 9 As shown, in some embodiments, the desulfurization device also includes a stirring rod 5, and the stirring rod 5 includes a rake portion 51 and a handle portion 52. The tank body 1 has a stirring hole connected to the desulfurization area 111. The rake portion 51 is located in the desulfurization area 111. It is the part of the stirring rod 5 that directly contacts the first desulfurizer 10, and is used to stir the first desulfurizer 10 and eliminate the gaps between the first desulfurizers 10; the handle portion 52 is the part connecting the rake portion 51 and the drive, and is connected to the rake portion 51 through the stirring hole, so that the staff can stir the first desulfurizer 10 in the desulfurization area 111 through the handle portion 52 outside the tank body 1.

[0073] Compared with the existing desulfurizer, there are residual gaps after filling, the desulfurizer is unevenly distributed (such as in a peak shape), the desulfurizer in the desulfurization device is not fully filled or not fully utilized, resulting in reduced desulfurization efficiency; in this embodiment, during the filling process of the first desulfurizer 10 and after the filling is completed, a stirring rod 5 can be used to stir to eliminate the gaps between the first desulfurizers, so that the first desulfurizer 10 is evenly distributed in the tank body 1, thereby improving the utilization rate of the first desulfurizer 10.

[0074] In some embodiments, the stirring rod 5 also includes a sealing portion 53 for ensuring the overall sealing of the desulfurization device. In this embodiment, the sealing portion 53 is covered at the connection between the handle 52 and the stirring hole. Specifically, the sealing portion 53 wraps the stirring hole and the part of the stirring rod 5 located outside the tank body 1 on the outer wall of the tank body 1 to prevent leakage of fuel gas during the desulfurization process and the stirring process.

[0075] Preferably, the material used for the sealing portion 53 includes synthetic leather, resin and rubber.

[0076] In some embodiments, a gas inlet pipe 6 is also included, and the gas inlet pipe 6 is inserted into the tank body 1 through the air inlet 12, and is used to pass the fuel gas into the accommodating chamber 11 for desulfurization. Among them, the gas inlet pipe 6 includes a transition section 61 and an output section 62, and the transition section 61 is connected to the output section 62. The pipe opening of the output section 62 at one end away from the transition section 61 is arranged toward the second cover body 15, so that when the fuel gas enters the buffer area 112 through the gas inlet pipe 6, since the output section 62 of the gas inlet pipe 6 is toward the end cover, it cooperates with the second cover body 15 with a certain curvature, which is conducive to the impact of the fuel gas on the inner surface of the second cover body 15 to be evenly dispersed, and enters the desulfurization area 111 after being diverted by the first diverter 21, so as to prevent the fuel gas from flowing too fast and distributing too concentratedly, resulting in the first diverter 21 being unable to fully play the diversion effect.

[0077] In some embodiments, an angle β is formed between the central axis of the end of the output section 62 away from the transition section 61 and the central axis of the tank body 1, and β is 0-90°.

[0078] This embodiment uses the above-mentioned structural setting and cooperates with the second cover body 15 with a certain curvature, which is conducive to the impact of the fuel gas on the inner surface of the second cover body 15 to be evenly dispersed, and enters the desulfurization area 111 after being diverted by the first diverter 21, preventing the fuel gas from flowing too fast and distributing too concentratedly, resulting in the first diverter 21 being unable to fully play the diversion role. Preferably, the angle β is 0-60°.

[0079] In some embodiments, the desulfurization device also includes a gas exhaust pipe 7, which is connected to the desulfurization area 111 through the gas outlet 13, so that after the fuel gas is desulfurized in the desulfurization area 111, it is discharged from the tank body 1 through the gas exhaust pipe and then introduced into the fuel cell system.

[0080] Read also Fig.10 Compared with the prior art, it is not possible to conveniently and quickly determine whether the desulfurizer is invalid, which may lead to untimely replacement of the desulfurizer. The desulfurization device in this embodiment also includes a sight glass 8, which is connected to the tank body 1 through the gas discharge pipe 7, so that the fuel gas after desulfurization in the desulfurization area 111 is further input into the sight glass 8. Among them, the sight glass 8 includes a visual cup body 81 for filling the second desulfurizer, so as to determine whether the first desulfurizer 10 in the desulfurization area 111 is invalid by observing the color of the second desulfurizer.

[0081] It can be understood that the outer wall of the cup body 81 is made of transparent material, and the second desulfurizer is filled inside the cup body 81. Once the second desulfurizer in the cup body 81 is observed to change color, it can be determined that the first desulfurizer 10 in the tank body 1 has failed, and the first desulfurizer 10 in the tank body 1 needs to be replaced in time. In this embodiment, by setting a sight glass 8 and observing whether the second desulfurizer in the cup body 81 changes color, it is determined whether the first desulfurizer 10 in the tank body 1 of the desulfurization device has failed. The above judgment method is simple and convenient, and has a high accuracy.

[0082] It should be noted that the first desulfurizer 10 and the second desulfurizer in this embodiment are the same desulfurizer.

[0083] like Figures 11 to 13 As shown, in some embodiments, the cup body 81 in this embodiment includes a second body 811, a first connecting part 812 and a second connecting part 813, the second body 811 has a cavity 8111, the first connecting part 812 has an air intake pipe 8121 for fuel gas to pass through, the second connecting part 813 has an air outlet pipe 8131, the first connecting part 812 and the second connecting part 813 are located at both ends of the second body 811, and the air intake pipe 8121 is connected to the air outlet pipe 8131 through the cavity 8111.

[0084] In this embodiment, the sight glass 8 further includes a second flow divider 82 and a second filter 83. The second flow divider 82 is installed in the cavity 8111 of the glass body 81, and the second desulfurizer is arranged in the cavity 8111. The second flow divider 82 is covered on the air intake pipe 8121, and the second filter 83 is arranged on the side of the second flow divider 82 away from the air intake pipe 8121; the second flow divider 82 is provided with a plurality of second flow divider holes 821 penetrating the second flow divider 82, and the second filter 83 is provided with a plurality of second filter holes 831 penetrating the second filter 83.

[0085] The fuel gas of this embodiment flows to the second flow divider 82 through the air intake pipe 8121, and flows into the cup body 81 after being evenly dispersed after passing through the second flow divider hole 821 of the second flow divider 82, which can prevent the fuel gas from being too concentrated and passing through the cup body 81 near the axis of the cup body 81, causing the problem that the second desulfurizer cannot be observed from the outside of the cup body 81. The second filter 83 separates the second desulfurizer from the second flow divider 82, and prevents the second desulfurizer from falling on the second flow divider 82 and blocking the second flow divider hole 821, thereby affecting the diversion effect of the fuel gas, while ensuring that the aperture of the second filter hole 831 is smaller than the particle diameter of the second desulfurizer. When the specification of the second desulfurizer is changed, the corresponding second filter 83 can be replaced.

[0086] In some embodiments, the second flow divider 82 and the second filter screen 83 are both in a hollow hemispherical shape.

[0087] The second diverter 82 in this embodiment utilizes a hemispherical structure to guide the fuel gas to disperse upward along its spherical surface, which is beneficial to the flow of the fuel gas; in addition, the second filter 83 is also a hollow hemispherical shape, which is similar to the structure of the second diverter 82, so as to facilitate the assembly of the two. The second filter 83 utilizes a hemispherical structure to guide the fuel gas to disperse upward along its spherical surface, which is beneficial to the flow of the fuel gas, so that the fuel gas can be evenly dispersed and then flow into the cup body 81, preventing the fuel gas from being too concentrated and passing through the cup body 81 near the axis of the cup body 81, resulting in the problem of the second desulfurizer changing color that cannot be observed from outside the cup body 81.

[0088] In some embodiments, a bracket 9 is further included, which is connected to the tank body 1 and supports the tank body 1 to prevent the desulfurization device from shaking during the desulfurization process. Preferably, there are three brackets 9 in this embodiment, which are arranged at equal angles around the axis of the tank body 1 and at the circumference of the tank body 1.

[0089] In summary, an embodiment of the present invention provides a desulfurization device, which is provided with a stirring rod 5 and a sealing part 53. While ensuring the sealing of the desulfurization device, the stirring rod 5 can be used to stir to eliminate the residual gaps after the first desulfurizer 10 is filled, so that the first desulfurizer 10 is evenly filled in the tank body 1, thereby improving the utilization rate of the first desulfurizer 10, so as to solve the problem of uneven distribution of the desulfurizer (peak-shaped) and large gaps between the desulfurizers after the existing desulfurizer is filled, thereby reducing the desulfurization efficiency.

[0090] In addition, a first diverter 21 and a first filter 22 are provided. The diverter can allow the fuel gas to evenly enter the desulfurization device tank 1, thereby improving the desulfurization efficiency. By replacing the first filter 22 of different specifications, multiple specifications of desulfurizers can be adapted, and the operation is simple. This solves the problem that the existing single desulfurization device cannot be adapted to multiple specifications of desulfurizers. After the desulfurizer specifications are changed, the desulfurization device needs to be replaced as a whole for adaptation, which is complicated to operate and time-consuming and labor-intensive.

[0091] Finally, a sight glass 8 is also provided. The outer wall of the cup body 81 in the sight glass 8 is made of transparent material. A certain amount of the second desulfurizer is filled inside the cup body 81. By observing whether the second desulfurizer in the cup body 81 changes color, it is determined whether the first desulfurizer 10 in the desulfurization device tank body 1 is invalid, so that the first desulfurizer 10 can be replaced in time. This is simple, convenient and fast, and avoids incomplete desulfurization, so as to solve the problem that it is impossible to conveniently and quickly determine whether the desulfurizer is invalid in the prior art, which easily leads to untimely replacement of the desulfurizer.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
