[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously pollutes the environment and affects human health. If a large amount of industrial waste gas is discharged into the atmosphere without being treated to meet the standards, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. In the process of waste gas treatment, waste gas fans are indispensable equipment.

[0003] In the prior art, there is an exhaust gas blower for waste acid regeneration with patent announcement number CN211449124U. The above patent realizes the adjustment of the size of the air inlet by setting a cylinder at the air inlet of the blower body, and setting a first baffle, a second baffle, an annular slide groove, a slide ring, a slideway and an adjusting rod in the cylinder. By sliding the adjusting rod in the position of the slideway, the slide ring is driven to slide in the annular slide groove, thereby driving the second baffle to cover the gap and adjust the size of the air inlet. However, there are still the following deficiencies in actual use: the interface position of the exhaust gas collection device and the exhaust gas blower of the existing exhaust gas blower is mostly fixed, which makes it inconvenient to disassemble and repair the exhaust gas blower when it is damaged, and when the use time is too long, some leakage is prone to occur at the connection between the blower and the exhaust gas collection device, causing impact on the environment.

[0004] Therefore, there is a need for an exhaust gas collection device for an exhaust gas blower that is easy to maintain, so as to solve the problems in the prior art that the blower on the exhaust gas collection device is difficult to disassemble and maintain, and gas leakage is prone to occur at the connection between the exhaust gas collection device and the blower after long-term use.

[0023] Further as Figure 2 As shown, it is worth explaining in detail that the connecting mechanism 8 includes two symmetrically distributed mounting shells 81, and the two mounting shells 81 are respectively fixedly connected to the top and bottom of the outer wall of the exhaust pipe 5, and the same limiting plate 82 is slidably connected between the inner walls at both ends of the mounting shell 81 and the inner walls on both sides, and a block 83 is fixedly connected to the limiting plate 82 at the center of the ground, and a spring 84 is fixedly connected to the top surface of the limiting plate 82, and the top of the spring 84 is fixedly connected to the inner wall of the top surface of the mounting shell 81, and sliders 85 are fixedly connected at the centers of the outer walls on both sides of the limiting plate 82, and the inner walls on both sides of the mounting shell 81 are provided with sliding grooves 86 that match the sliders 85, and the outer wall at one end of the mounting shell 81 is provided with a movable groove 87, and a movable plate 88 is fixedly connected to the outer wall of one end of the limiting plate 82 corresponding to the movable groove 87, and the outer wall of one end of the movable plate 88 extends to the outside of the mounting shell 81 through the movable groove 87.

[0024] Further as Figure 2 As shown, it is worth explaining in detail that the connecting mechanism 8 also includes two symmetrically distributed grooves 89, which are respectively opened at the top and bottom of the outer wall of the air outlet pipe 7, and the inner surfaces of the two grooves 89 are respectively in contact with the outer surfaces of the two blocks 83.

[0025] Further as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the protection mechanism 9 includes two fixed rings 91 distributed in parallel, the inner side walls of the two fixed rings 91 are fixedly connected to the outer side walls of the exhaust pipe 5 and the exhaust pipe 7 respectively, the outer side walls of the fixed rings 91 are provided with fixed grooves 92, and the inner side walls of the fixed grooves 92 are fixedly connected with sealing gaskets 93, the upper parts of the two fixed rings 91 are movably connected to the same first protective cover 94 through the fixed grooves 92, and the lower parts of the two fixed rings 91 are movably connected to the same second protective cover 95 through the fixed grooves 92, and the bottom surfaces of the outer side walls of the first protective cover 94 and the second protective cover 95 are movably connected to the first protective cover 94 and the second protective cover 95.

The operation is simple, and the problem of the fan on the exhaust gas collection device being difficult to disassemble and maintain is effectively avoided.

[0029] When the exhaust pipe 5 and the exhaust pipe 7 are connected, the first protective cover 94 and the second protective cover 95 are clamped on the fixing ring 91 through the fixing groove 92.

When the exhaust gas leaks from the connection between the exhaust pipe 5 and the exhaust pipe 7, the exhaust gas will be collected by the enclosed space formed by the first protective cover 94 and the second protective cover 95. At the same time, the gas alarm 99 sounds an alarm to remind the staff to deal with the leaked gas to avoid further expansion of the exhaust gas leakage, which effectively avoids the problem of gas leakage at the connection between the exhaust gas collection device and the fan after long-term use.
