DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] In the embodiments of the present application, please refer to Figure 1 and 3, a hydrogen compressor water mist collector, including a hydrogen compressor 10. An air outlet pipe 11 is provided at the bottom of the hydrogen compressor 10. The hydrogen compressor 10 can be an existing one, and the air outlet pipe 11 is also an existing one. The fixed shell 20 is fixedly connected to the bottom of the air outlet pipe 11 in an existing manner. An air cavity 30 extending to the bottom of the fixed shell 20 is opened inside the fixed shell 20. A fixed pipe 40 located inside the air cavity 30 is fixed inside the fixed shell 20. The fixed pipe 40 is communicated with the air outlet pipe 11. A sealing cover 60 blocking the air cavity 30 is threadedly connected to the bottom of the fixed shell 20. A water collecting tank 61 is opened at the top of the sealing cover 60. The bottom of the fixed pipe 40 is aligned with the water collecting tank 61. A first filtering structure 50 is provided between the fixed pipe 40 and the fixed shell 20. A second filtering structure 70 communicated with the top end of the air cavity 30 is provided on the side of the fixed shell 20. The fixed shell 20 is fixedly connected with a connecting pipe 80 communicated with the second filtering structure 70. The connecting pipe 80 is used to connect to an external device, and it can be an existing connecting pipeline;

[0042] During use, the hydrogen discharged from the hydrogen compressor 10 will be discharged into the air cavity 30 through the fixed pipe 40. Larger liquids or even solids contained inside will directly fall onto the sealing cover 60. The hydrogen will then be filtered by the first filtering structure 50 during transmission and sent to the upper end of the air cavity 30, and then sent to the next device connected to it through the connecting pipe 80 after passing through the second filtering structure 70. The operation is simple. Through two groups of filtering structures, the filtering effect can be effectively increased. And larger particle impurities will directly fall into the water collecting tank 61 and be collected, increasing the effect of filtering and treating hydrogen. When it is necessary to process and collect the liquid, just unscrew the sealing cover 60.

[0043] In a further embodiment, please refer to Figure 1 and 3 , the air cavity 30 is cylindrical. At the same time, the first filtering structure 50 includes two fixed sleeves 51 and a filtering plate 52. The filtering plate 52 is annular and fixed between the two fixed sleeves 51. The material of the filtering plate 52 can be the material commonly used for hydrogen filtering in the existing technology, and no change is made in this application. If the texture is relatively soft, a rod body is fixed between the two fixed sleeves 51 for support and fixation. One of the fixed sleeves 51 is sleeved outside the fixed pipe 40, and the other is close to the inner wall of the air cavity 30. Sealing rings 53 are provided between the fixed sleeve 51 and the fixed pipe 40 and between the fixed sleeve 51 and the inner wall of the air cavity 30. Two fixed rods 54 are fixed to the bottom of the fixed sleeve 51. The bottom of the two fixed rods 54 is fixedly connected with a connecting rod 55. When it is necessary to replace the filtering plate 52, after unscrewing the sealing cover 60, then hold the connecting rod 55 and pull down, and the fixed rods 54, the fixed sleeve 51 and the filtering plate 52 can be removed. Conversely, it can be installed. The operation is simple and convenient for disassembly and replacement.

[0044] In a further embodiment, please refer to Figure 1 and 2, the second filtering structure 70 includes a connection hole 71 formed in the side surface of the fixed housing 20. The connection hole 71 is a stepped hole and is communicated with the top end of the air cavity 30. A connection cylinder 72 is slidably arranged inside the connection hole 71. A plurality of rubber sealing rings are sleeved outside the connection cylinder 72. A filter element 73 is arranged inside the connection cylinder 72. The material of the filter element 73 can also be the commonly used filtering material for hydrogen filtering in the prior art. A sealing pad 74 that abuts against the inner wall of the connection hole 71 is fixed at the end of the connection cylinder 72. A rotating cover 75 is threadedly connected to the end of the connection hole 71. The connection cylinder 72 is fixedly connected with a top block 76 that abuts against the rotating cover 75. An air outlet hole 77 that is communicated with the connecting pipe 80 and the filter element 73 is formed in the side surface of the connection cylinder 72. When in use, after the hydrogen is filtered by the filter element 73, it is discharged through the air outlet hole 77 and the connecting pipe 80. When replacement is needed, unscrew the rotating cover 75, and then pinch the top block 76 and pull forcefully to draw out the connection cylinder 72, and then replace the filter element 73. Conversely, it can be installed. The operation is simple and convenient for replacement.
