[0060] In this embodiment, the swing of the toggle plate 17 further drives the rotating ring 37 to roll on the roller frame 38, so that the sliding column 40 slides in the sliding groove 41, and then drives the second crankshaft 39 to swing with the rotating column 26 as the axis, and at the same time drives the rotating column 26 to swing, and then drives the fan-shaped piece 25 to swing, and the swing of the fan-shaped piece 25 affects the flow direction of the exhaust gas in the exhaust gas treatment pipe 1, so that the exhaust gas becomes chaotic in the exhaust gas treatment pipe 1;

[0061] The setting of the spoiler component affects the flow direction of the exhaust gas in the exhaust gas treatment pipe 1 by swinging the fan-shaped piece 25, so that the exhaust gas becomes chaotic in the exhaust gas treatment pipe 1, thereby preventing the exhaust gas from generating vortexes and generating noise, and further reducing the generation of noise.

[0062] Embodiment 2, based on the above embodiment:

[0063] See also Figure 2 , Figure 3 and Figure 4 The noise treatment system includes an air outlet shielding assembly, which is arranged in the exhaust gas treatment pipe 1 and is transmission-connected to the spoiler assembly. The air outlet shielding assembly includes a connecting block 18, and the surface of the connecting block 18 is fixedly connected to the end surface of the toggle plate 17. The surface of the connecting block 18 is also fixedly connected to an air baffle plate 8, and the surface of the air baffle plate 8 is slidingly connected to the inner wall of the exhaust gas treatment pipe 1. Fifteen air baffle plates 8 are provided, and the gap between each air baffle plate 8 is the same, and the surfaces of the fifteen air baffle plates 8 are connected by a connecting plate 7.

[0064] In this embodiment, during the swinging process of the toggle plate 17, the air baffle plate 8 will be further driven together with the connecting block 18 to slide on the inner wall of the exhaust gas treatment pipe 1, and the noise treatment system for exhaust gas purification has the following two exhaust modes during the sliding process;

[0065] First, when the toggle plate 17 swings to drive the fan-shaped piece 25 to gradually move in a non-horizontal direction, the fan-shaped piece 25 has a smaller blocking effect on the exhaust gas, and the toggle plate 17 will further drive the air baffle plate 8 to move, gradually blocking the air outlet 6, so that the exhaust gas can pass through the exhaust gas treatment pipe 1 and go out of the exhaust pipe 4;

[0066] Second, when the toggle plate 17 swings and drives the fan-shaped piece 25 to gradually move in the horizontal direction, the fan-shaped piece 25 has a greater blocking effect on the exhaust gas, which will interfere with the flow of the exhaust gas. At this time, the toggle plate 17 will further drive the air baffle plate 8 to move, gradually expand the air outlet 6, and further allow the exhaust gas to go out from the air outlet 6, thereby reducing the impact of the turbulence on the exhaust effect of the noise treatment system for exhaust purification;

[0067] The setting of the air outlet shielding component is to gradually block the air outlet 6 by driving the air baffle plate 8 to move when the fan-shaped piece 25 gradually moves in a non-horizontal direction. At this time, since the fan-shaped piece 25 has a smaller blocking effect on the exhaust gas, the air baffle plate 8 can be used as a blocking member to prevent external impurities from entering the exhaust gas treatment pipe 1 and affecting the inside of the exhaust gas treatment pipe 1. The air outlet 6 is gradually expanded by driving the air baffle plate 8 to move when the fan-shaped piece 25 gradually moves in a horizontal direction, and the exhaust gas can further be discharged from the air outlet 6, thereby reducing the influence on the exhaust effect of the noise treatment system for exhaust purification during turbulence.

[0068] Embodiment 3, based on the above embodiment:

[0070] A fixing ring 14, the outer surface of which is fixedly connected to the outer surface of the set 11, the inner wall of which is fixedly connected to an arc container 15, the inner wall of which is slidably connected to a piston 16, the rod end of the piston 16 is fixedly connected to a fixing column 21, and the end surface of the fixing column 21 away from the piston 16 is fixedly connected to the end surface of the toggle plate 1 17;

[0071] A one-way valve 22, the outlet end of the one-way valve 22 is fixedly connected to the bottom end face of the arc-shaped container 15, the inlet end of the one-way valve 22 is fixedly connected to a connecting pipe 23, and the end of the connecting pipe 23 away from the one-way valve 22 is fixedly connected to a feeding pipe 3, the end face of the feeding pipe 3 penetrates the end face of the exhaust gas treatment pipe 1, and a total of three groups of one-way valves 22 and connecting pipes 23 are provided, and the three groups of one-way valves 22 and connecting pipes 23 are also linearly arranged inside the exhaust gas treatment pipe 1, and each group of one-way valves 22 and connecting pipes 23 corresponds to each kit 11;

[0073] In this embodiment, the piston 16 is further prevented from sliding in the arc container 15 by the swing of the toggle plate 17, and the reductant (exhaust treatment liquid) in the feed pipe 3 is transported to the annular atomizing spray plate 27 for atomization and spraying in cooperation with the one-way valve 1 22 and the one-way valve 2 29, so that the exhaust treatment liquid is fully contacted and mixed with the exhaust gas in the exhaust treatment pipe 1, and the exhaust pollutants are efficiently catalytically converted to meet the exhaust emission requirements; specifically, the main purpose of the process implemented in this application is to reduce nitrogen oxides, and the exhaust treatment liquid solution (commonly referred to as AdBlue or DEF, i.e., diesel vehicle exhaust treatment liquid) is injected into the exhaust flow in the SCR system, and chemically reacts with nitrogen oxides to convert them into nitrogen (N2) and water vapor (H2O), both of which are harmless to the environment.

[0074] The exhaust gas purification component is set up to spray the exhaust gas treatment liquid in atomization through the annular atomizing spray plate 27, so that the exhaust gas treatment liquid is fully contacted and mixed with the exhaust gas in the exhaust gas treatment pipe 1, and the exhaust pollutants are efficiently catalytically converted to meet the exhaust gas emission requirements, further improving the exhaust gas purification effect of the noise treatment system for exhaust purification.

[0075] The noise treatment method for exhaust purification is as follows:

[0076] Connect the air intake pipe 2 to the exhaust outlet, connect the feed pipe 3 to the reducing agent storage cylinder, and then start the motor 36 to drive the exhaust gas purification noise treatment system to operate;

[0078] During the swinging of the toggle plate 17 and the toggle plate 2 19, the air baffle plate 8 is also driven to block the air outlet 6, and the exhaust mode of the noise treatment system for exhaust purification is further changed according to the movement state of the fan-shaped piece 25;

[0079] During the swinging process of the toggle plate 17 and the toggle plate 2 19, the annular atomizing spray plate 27 is also driven to spray the reducing agent (i.e., the exhaust gas treatment liquid) in an atomized manner, so that the reducing agent is fully contacted and mixed with the exhaust gas in the exhaust gas treatment pipe 1, and the exhaust pollutants are efficiently catalytically converted to meet the exhaust gas emission requirements;

[0080] After being processed by various components in the waste gas treatment pipe 1, the waste gas is finally discharged.
