[0002] The fuel cell air compressor plays a crucial role in the fuel cell system and can be compared to the "lungs" of the fuel cell. It is mainly responsible for providing appropriate pressure and amount of oxygen to the stack. By compressing air, the air compressor provides the necessary oxygen for the stack reaction, thereby ensuring the efficient operation of the fuel cell system. The main function of the fuel cell air compressor is to provide clean air with specific pressure and flow rate to the stack to ensure the oxygen supply required for the stack reaction. The performance of the air compressor directly affects the efficiency and reliability of the fuel cell system; The turbocharging system in the fuel cell air compressor is a technology that uses the exhaust gas discharged from an internal combustion engine to drive the turbine to rotate, and then drives the compressor to compress air. This system improves the air density entering the cylinder, thereby enhancing the power and efficiency of the engine. The turbocharging system uses the exhaust gas discharged from the internal combustion engine to drive the turbine to rotate, and the rotational power of the turbine drives the compressor to compress air.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] The present invention provides a turbocharging system for a fuel cell air compressor, including a fixed seat 1; Turbocharging mechanisms 2 for gas compression are provided at both ends of the fixed seat 1, an oil injection mechanism 3 for lubrication is provided at the top of the fixed seat 1, a first gas treatment mechanism 4 for air treatment is provided at one end of the turbocharging mechanism 2, a second gas treatment mechanism 5 for waste gas treatment is provided at the other end of the turbocharging mechanism 2, and a support mechanism 6 for seismic bearing is provided at the bottom of the fixed seat 1; The first gas treatment mechanism 4 includes a connection assembly, an elastic assembly, a filtering assembly, and a cover assembly. The connection assembly is provided at one end of the turbocharging mechanism 2, the elastic assembly is provided inside the connection assembly, the filtering assembly is provided inside the connection assembly, and the cover assembly is provided at one end of the connection assembly; Through the cooperation between the connection assembly, the elastic assembly, the filtering assembly, and the cover assembly, the air before entering the air compressor can be filtered, which can not only protect the turbine group during the supercharging process, but also protect the air compressor, so as to operate stably for a long time, without the need to frequently replace the turbine components, and the filter element can be quickly replaced.

[0023] The entering air is filtered by the first gas treatment mechanism 4, the entering waste gas is filtered by the second gas treatment mechanism 5, lubricant is injected according to the oil injection mechanism 3 for lubrication during rotation, and the second gas treatment mechanism 5 is seismically supported by the support mechanism 6.

[0024] Among them, As Figure 2 、 3 As shown in 4, the turbocharging mechanism 2 includes a turbocharger body 21. The turbocharger bodies 21 are respectively fixedly installed at both ends of the fixed seat 1. An exhaust port 23 is provided on the side of one turbocharger body 21, and an exhaust gas inlet 22 is provided at one end of one turbocharger body 21, which is convenient for realizing the pretreatment when the exhaust gas is discharged, can assist in cooling the exhaust gas, and can also protect the turbine group when the pretreated gas enters the corresponding turbine group; On the side of the other turbocharger body 21, an air discharge port 25 is provided, and an air inlet 24 is provided at the end of the other turbocharger body 21, realizing the pretreatment operation when air enters the turbine group, not only protecting the turbine group, but also protecting the air compressor, and avoiding damage caused by impurities.

[0025] As shown in the figure, there are two turbines in the turbine group. Its principle mainly uses the exhaust gas discharge to drive the left turbine to rotate, and a connecting shaft is installed between the two groups of turbines. Therefore, when the left turbine rotates, it can drive the right turbine to rotate. When the right turbine rotates, the supercharged intake and exhaust operation can be realized.

[0026] Preferably; As Figure 5 shown, the connecting component includes an outer tube 41. The outer tube 41 is connected to the air inlet 24. A connecting ring 42 is fixedly installed on the inner side wall of the outer tube 41. The connecting ring 42 is inserted into the inside of the air inlet 24, realizing the gas auxiliary conveying operation during air intake, and being able to support and connect the internal components.

[0027] As Figure 5 shown, the elastic component includes an installation groove 43. The installation groove 43 is opened on the inner side wall of the outer tube 41. A first spring 44 is welded on the inner side wall of the installation groove 43. One end of the first spring 44 is welded with a retaining ring 45, playing an elastic tightening role, so as to facilitate the quick installation and disassembly of the first filter element 46.

[0028] As Figure 6 shown, the filtering component includes a sliding groove 410. The sliding grooves 410 are respectively opened at the bottom and top of the inner cavity of the outer tube 41. A rotating groove 411 is also opened on the inner side wall of the outer tube 41. A connecting block 47 is slidably connected inside the rotating groove 411. A first filter element 46 is fixedly installed on the inner side of the connecting block 47, preprocessing the gas according to the filtering method, and facilitating its disassembly and assembly during installation.

[0029] As Figure 6 shown, the sealing component includes an end cover 48. The end cover 48 is threadedly connected to the outside of one end of the outer tube 41. A pressing ring 49 is fixedly installed inside the end cover 48, playing an auxiliary role in limiting the first filter element 46 to ensure that the first filter element 46 is stably located inside the outer tube 41.

[0030] The above-mentioned first filter element 46 can be any one or a combination of two or more of chemical fiber filter elements, paper non-woven filter elements, metal filter elements, polyester fiber filter elements, polypropylene fiber filter elements and glass fiber filter elements according to the usage situation and actual needs.

[0031] As shown in the figure in the installation state, when installation is required, take out the required first filter element 46, and then insert it into the interior of the outer tube 41. At this time, the connecting block 47 slides inside the chute 410 until it contacts the retaining ring 45 and applies a thrust to the retaining ring 45, causing the retaining ring 45 to compress the first spring 44. Then, when it is pushed horizontally until it cannot slide, the thrust is changed to a rotational force. At this time, the connecting block 47 rotates inside the rotating groove 411 until it cannot rotate, and then the installation operation can be completed. At this time, take out the end cover 48 and align it with the corresponding end of the outer tube 41 for threaded connection, and make the pressing ring 49 contact one end of the first filter element 46 to complete the installation operation; When the turbocharging system works, air will enter the interior of the first filter element 46 and be filtered, so as to ensure that the gas entering the turbine and the interior of the air compressor is clean gas, realizing the protection of both; When disassembling, just operate in the reverse order of installation. Rotate the end cover 48 counterclockwise to remove it, then slightly push the first filter element 46 and rotate it until the connecting block 47 is inside the chute 410, and then slowly pull it out. When it is inside the chute 410, it will apply a short-distance push to the retaining ring 45 according to the first spring 44, so as to facilitate the operator to conveniently and directly take out the first filter element 46; Based on the above, while protecting the turbine equipment, it is also possible to protect the air compressor, and when the first filter element 46 needs to be replaced, the operation is simple and convenient, which is beneficial to use and improves the efficiency during maintenance and replacement.

[0032] It is worth noting; As Figure 7 and 8 As shown, the second gas treatment mechanism 5 includes an installation pipe 51, which is bolted to the exhaust gas inlet 22. A delivery pipe 52 is fixedly installed through the inner side wall of the installation pipe 51. An internal thread ring 53 is fixedly installed on the inner side wall of one end of the installation pipe 51. A fixed cover 55 is threadedly connected inside the internal thread ring 53. A second filter element 54 is bolted to the inner side wall of the fixed cover 55, which can pre-treat the discharged exhaust gas, thus avoiding damage to the corresponding turbine.

[0033] When the air compressor generates pressurized exhaust gas, it will directly enter the installation pipe 51 and be processed by the second filter element 54. As described above, the second filter element 54 used here can be any one or a combination of two or more of a chemical fiber filter element, a paper non-woven filter element, a metal filter element, a polyester fiber filter element, a polypropylene fiber filter element, and a glass fiber filter element according to the usage situation and actual requirements; Only after the gas passes through the second filter element 54 will it be discharged into the corresponding turbine space, causing the corresponding turbine to rotate. Before the exhaust gas is discharged, water needs to be discharged into the interior of the delivery pipe 52 through the water circulation system. The delivery pipe 52 is located inside the installation pipe 51 in a wrapped manner to assist in cooling the discharged exhaust gas, avoiding damage to the turbine system caused by long-term discharge of high-temperature gas, and further improving the protection effect on the turbine.

[0034] As shown in the figure in the installation state, when installing, the second filter element 54 is directly installed through the installation pipe 51. The installation pipe 51 is installed at the intake position of the turbine system by bolting. Therefore, when installing the filter element, it can be directly installed through it into the installation pipe 51, that is, the state shown in the figure. Then, the second filter element 54 is driven to rotate by the fixed cover 55, and the fixed cover 55 is in a threaded connection state with the internal thread ring 53, thereby increasing its connection effect. When disassembling, just operate in the reverse direction according to the above method. Rotate the fixed cover 55 counterclockwise to separate it from the internal thread ring 53 and at the same time drive the second filter element 54 to move and then disengage from the installation pipe 51, thus completing the disassembly operation. Then, replace the new second filter element 54 according to the above installation method.

[0035] According to the above, the turbine components can be effectively protected. The incoming gas is processed by means of pre-treatment filtration to protect the turbine components from damage. At the same time, it can also pre-treat the air before it enters, and also uses the filtration method to block impurities to ensure the cleanliness of the gas entering the air compressor and avoid damage to the air compressor caused by impurities in the untreated air. While protecting the turbine equipment and the air compressor, it also has the advantages of being convenient for disassembling and replacing the filter element. It is not only simple and convenient to operate, but also can improve the efficiency during the replacement operation.

[0036] Furthermore; As Figure 4 shown, the oil injection mechanism 3 includes a top cover seat 31. The top cover seat 31 is bolted to the top of the fixed seat 1. An oil injection flow channel 32 is opened inside the top cover seat 31. The top end of the oil injection flow channel 32 is communicated with a connecting pipe 33 to achieve active lubrication operation, so as to continuously rotate stably without the occurrence of rotation blockage, and further improve the effect during the operation of the turbine.

[0037] Connect the connecting pipe 33 to the corresponding container containing lubricating fluid or lubricant, and then cause the above-mentioned lubricating fluid to enter the temporary storage space inside the connecting pipe 33. Based on the fact that a control valve is also installed on the connecting pipe 33, when the control valve is opened, the lubricating fluid can directly enter the interior of the oil injection flow channel 32 and then be distributed and transported to the corresponding positions to lubricate the rotating positions. It can facilitate the lubrication operation of the rotating and transmission parts to ensure the smoothness of its transmission and rotation, improve the turbocharging effect while rotating efficiently.

[0038] Finally; The support mechanism 6 includes a bearing component and an earthquake-resistant component. The bearing component is arranged at the bottom of the fixed seat 1, and the earthquake-resistant component is arranged at the bottom of the bearing component.

[0039] As Figure 10 shown, the bearing component includes a support seat 61. The support seat 61 is bolted to the bottom of the fixed seat 1. First perforations 62 are formed at both ends of the top of the support seat 61, realizing support and auxiliary ventilation operations; As Figure 11 shown, the earthquake-resistant component includes a fixing plate 63. The fixing plate 63 is fixedly installed on the inner side wall of the support seat 61. A second spring 65 and a damper 66 are fixedly installed at the bottom of the fixing plate 63. The second spring 65 is located outside the damper 66. Second perforations 64 are formed at both ends of the top of the fixing plate 63. The bottom ends of the second spring 65 and the damper 66 are both fixedly installed with an outer cover seat 67. A partition net 68 is fixedly installed on the outside of the outer cover seat 67, which can support and carry out earthquake-resistant operations on the above-mentioned turbocharging system, avoid excessive vibration and large-amplitude vibration from damaging it, and ensure its stable operation.

[0040] For earthquake-resistant treatment, when the above operation is in the pressurization process, the overall component will generate vibration force due to the rotational force. The higher the rotational speed and the longer the duration, the greater the vibration. When vibration occurs, it will be conducted through the support seat 61, and at the same time, the fixing plate 63 will be directly synchronized. When the fixing plate 63 conducts, it will directly press down the second spring 65 and the damper 66. According to the second spring 65 and the damper 66, shock absorption and earthquake-resistant treatment operations are realized for the generated vibration force to ensure the stable operation of the equipment. At the same time, the cooperation between the second spring 65 and the damper 66 can form a shock absorber, or an earthquake-resistant and shock-absorbing device in the prior art can also be used; It has the effects of bearing and earthquake resistance. According to the adaptable installation, it can completely fit with the turbocharging mechanism 2, and reduce the vibration during equipment operation through the principles of shock absorption and vibration absorption, avoiding damage to the equipment and ensuring the stability during equipment operation.
