The utility model has the characteristic of good diversion effect.

[0003] When transporting waste gas, it needs to be treated at high pressure to become high-pressure gas before being transported to the treatment device. When the gas flow in the transport pipeline is too large at the same time, the pipe pressure will increase and cause it to be damaged. The above-mentioned documents do not have measures to protect the pipe on the intake pipe for transporting waste gas to reduce damage to the pipe. The cost of replacing pipes for industrial waste gas treatment is also relatively high. Protecting the pipe from damage is also a way to reduce maintenance costs. Utility Model Content

The air inlet pipe 2 is connected to the first branch pipe 4 and the second branch pipe 5 respectively. The first branch pipe 4 and the second branch pipe 5 are both provided with a limiting mechanism.

[0018] The limiting mechanism is composed of a mounting frame 60, a hydraulic cylinder 61, a baffle 62 and a limiting ring 63. The two hydraulic cylinders 61 are respectively installed on the first branch pipe 4 and the second branch pipe 5 through the mounting frame 60. The telescopic ends of the hydraulic cylinders 61 extend into the pipe and are connected to the baffle 62. The limiting rings 63 are arranged on the inner walls of the first branch pipe 4 and the second branch pipe 5.

[0019] Specifically, sealing strips 7 are provided at the positions where the telescopic ends of the two hydraulic cylinders 61 extend into the first branch pipe 4 and the second branch pipe 5 .

[0020] Example 2

[0021] When using the utility model, the gas flow meter 3 can detect the gas flow in the intake pipe 2. When the gas flow is too large, the hydraulic cylinder 61 installed on the first branch pipe 4 is started, and the hydraulic cylinder 61 is extended and retracted to drive the baffle 62 to move upward, so that the first branch pipe 4 is opened to divert the gas to the intake pipe 2, thereby preventing the excessive gas flow from causing the internal pipe pressure of the intake pipe 2 to increase and damage it.

[0022] Similarly, the hydraulic cylinders 61 on several branch pipes can be selected and started according to the gas flow in the intake pipe 2, and several branches can be opened to divert the protection pipeline.
