[0021] Please refer to Figures 1 to 4 A generator set tail gas purification device, including purification box 1, the inner wall of purification box 1 is fixedly connected with partition 2, partition 2 divides the dirty gas cavity 101 and clean gas cavity 102 in purification box 1, the lateral wall of partition 2 is connected with the opening of a plurality of purification ports 201, a plurality of purification ports 201 are all connected with closed assembly, a plurality of purification ports 201 are all connected with limiting assembly on the side close to clean gas cavity 102, the side of clean gas cavity 102 away from dirty gas cavity 101 is connected with the opening of a plurality of mounting ports 103, and limiting assembly is connected with adjacent mounting port 103 and is provided with metal filter core 3.

[0022] As Figures 1 to 4 The main improvement point of the utility model lies in that the purification operation of the tail gas of generator set can be continuously carried out by using other metal filter cores 3 while replacing part of metal filter cores 3, and the tail gas purification efficiency is improved. Figures 1 to 4As shown in the utility model, the generator set tail gas purification device in the utility model is used, metal filter core 3 is inserted into clean gas cavity 102 through the installation opening 103 of the side of the purification box 1, and the metal filter core 3 air inlet end is aligned with the purification port 201 of the baffle 2 through the limiting assembly, when the tail gas of the generator set enters the dirty gas cavity 101, respectively enters the inside of multiple metal filter cores 3 through multiple purification ports 201, after being filtered through the metal filter core 3, clean gas is discharged from the outside wall of the metal filter core 3 to the clean gas cavity 102, and then can be discharged, when part of the metal filter core 3 filtering performance decreases or is damaged, the metal filter core 3 can be extracted from the clean gas cavity 102 through the installation opening 103, and at the same time, the purification port 201 is closed through the closing assembly in the purification port 201, so that the unfiltered tail gas enters the clean gas cavity 102 from the purification port 201, so that the purification operation of the whole purification device does not need to be stopped, so that the purification box 1 can continuously carry out the purification operation of the tail gas, and the purification efficiency of the generator set tail gas is improved.

[0023] As Figures 1 to 4 As shown, the air inlet of the end of the metal filter core 3 is communicated with the adjacent purification port 201, the end of the metal filter core 3 away from the baffle 2 is screw connected with the installation opening 103, and the end of the metal filter core 3 away from the baffle 2 is fixedly connected with the pull ring 11. Through the pull ring 11, the installation or dismounting operation of the metal filter core 3 in the installation opening 103 can be facilitated, and at the same time, the threaded connection mode between the metal filter core 3 and the installation opening 103 is utilized, so that the metal filter core 3 after installation is not impacted and loosened when the tail gas enters the inside for purification, and the stability of the metal filter core 3 installed in the clean gas cavity 102 is ensured.

[0024] As Figure 1 And Figure 2 As shown, the top of the dirty gas cavity 101 is fixedly connected and communicated with the tail gas access pipe 12, and the top of the clean gas cavity 102 is fixedly connected and communicated with the clean gas discharge pipe 13. Through the tail gas access pipe 12, the tail gas generated by the generator set can be conveniently transported into the purification box 1 through a hose or a vertical pipeline, and after being filtered and purified through the metal filter core 3, the tail gas can be discharged to a designated position or a specific equipment for pollution detection after purification, so that the applicability of the purification box 1 is improved.

[0025] As Figures 2 to 4As shown, the limiting assembly includes a limiting tube 4 and a plurality of track rods 5, the limiting tube 4 is communicated with the purification port 201, and the limiting tube 4 is fixedly connected to the side of the baffle 2 close to the clean gas cavity 102, the plurality of track rods 5 are all fixedly connected to the side of the limiting tube 4 away from the baffle 2, the other end of the plurality of track rods 5 are all fixedly connected to the side of the clean gas cavity 102 away from the baffle 2, the metal filter core 3 is located in the plurality of track rods 5, and the metal filter core 3 is in sliding connection with the plurality of track rods 5 and the limiting tube 4. When the metal filter core 3 is inserted into the clean gas cavity 102 from the installation port 103, through the plurality of track rods 5, the metal filter core 3 can be stably moved inward and finally inserted into the limiting tube 4, so as to be aligned with the purification port 201 of the baffle 2, so that the installation of the metal filter core 3 is more stable, and at the same time, the exhaust gas entering the metal filter core 3 is discharged from the outside of the metal filter core 3 after purification, and the design of the plurality of track rods 5 enables the purified gas to be smoothly discharged from the metal filter core 3 into the clean gas cavity 102.

[0026] As shown in Figure 3 and Figure 4 The closing assembly includes a blocking block 6, a connecting rod 7, a pressing rod 8 and two limiting rods 9, the connecting rod 7 is located in the purification port 201, one end of the connecting rod 7 close to the dirty gas cavity 101 is fixedly connected with the blocking block 6, one end of the connecting rod 7 close to the clean gas cavity 102 is fixedly connected with the pressing rod 8, both ends of the pressing rod 8 close to the side of the connecting rod 7 are respectively fixedly connected with the two limiting rods 9, the other end of the two limiting rods 9 all penetrates the baffle 2 and extends into the dirty gas cavity 101, and the side of the pressing rod 8 away from the baffle 2 is abutted with one end of the metal filter core 3 close to the air inlet. When the metal filter core 3 is inserted into the limiting tube 4, the end of the metal filter core 3 will extrude the pressing rod 8 to the baffle 2, thereby driving the connecting rod 7 and the blocking block 6 to move into the dirty gas cavity 101, so that the blocking state of the blocking block 6 to the purification port 201 is opened, so that the dirty gas cavity 101 is communicated with the purification port 201, at this time, the exhaust gas in the dirty gas cavity 101 can enter the limiting tube 4 through the purification port 201, and then enter the metal filter core 3 for exhaust gas purification, when the metal filter core 3 is pulled out and disassembled to the outside, the extrusion force of the metal filter core 3 to the pressing rod 8 disappears, and the exhaust gas in the dirty gas cavity 101 pushes the blocking block 6 to the purification port 201, so that the blocking block 6 blocks the purification port 201, that is, the metal filter core 3 is pulled out, and the purification port 201 is blocked, in this process, the two limiting rods 9 can limit the blocking block 6, the connecting rod 7 and the pressing rod 8, to ensure that the blocking block 6 and the connecting rod 7 are located on the central axis of the purification port 201.

[0027] As shown in Figure 3 and Figure 4As shown in the drawings, the outer side of the limiting rod 9 is connected with a spring 10, the spring 10 is sleeved with the limiting rod 9, and the two ends of the spring 10 are fixedly connected with the partition plate 2 and the extrusion rod 8 respectively.

The blocking block 6 is designed as a conical structure, so that the blocking effect of the blocking block 6 on the purification port 201 is improved.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model.
