[0034] The regulating plug 5 - 4 is arranged in a stepped shape, and its diameter increases step by step from left to right.

[0035] A method for using an electric power carbon emission metering device, the method comprising the following steps:

[0036] S1: Connect the exhaust pipe to the air inlet end 1-3 in a fixed manner;

[0037] S2: The exhaust gas passes through the filter 2-6 to filter out impurities and enters the cooling box 5-1;

[0038] S3: The exhaust gas is cooled in the cooling box 5-1 and then measured;

[0039] S4: Push the lower rod 3-7 upward to clean the filter 2-6 from impurities.

[0040] The working principle of the present invention is:

[0041] When using the device, the exhaust pipe is fixedly connected to the air inlet end 1-3, and the exhaust gas enters the housing 1 through the air inlet end 1-3, and then passes through the filter 2-6 to filter out impurities in the exhaust gas, and then enters the exhaust gas outlet end 1-1 through the top of the fixing ring 2-1, and then enters the cooling box 5-1 from the exhaust gas outlet end 1-1. The regulating plug 5-4 is inserted into the exhaust gas outlet end 1-1, which can change the diameter of the exhaust gas outlet end 1-1, thereby reducing the exhaust gas compression flow rate at the left end of the regulating plug 5-4. When the exhaust gas passes through the regulating plug 5-4, the flow rate increases, and the rapid release in the cooling box 5-1 can reduce the temperature of the exhaust gas, and at the same time, the copper plate 5- 2. Further cooling the exhaust gas can prevent the exhaust gas from being too hot and having poor fluidity, which may affect the accuracy of the meter. As the exhaust gas continues to enter the cooling box 5-1, the exhaust gas in the cooling box 5-1 is pushed into the carbon dioxide meter 6 for metering. The screw 5-3 is rotated to drive the regulating plug 5-4 to move into the outlet end 1-1. The regulating plug 5-4 is arranged in a stepped shape to adjust the gap between the regulating plug 5-4 and the inner wall of the outlet end 1-1, thereby adjusting the flow rate of the exhaust gas. The adjustment can be made according to the temperature of the exhaust gas. If the exhaust gas temperature is too high, the gap between the regulating plug 5-4 and the outlet end 1-1 is reduced, and the flow rate of the exhaust gas is increased to quickly release and cool the exhaust gas.

[0042] When the filter screen 2-6 is clogged by impurities, it will affect the flow of exhaust gas. The lower rod 3-7 is pushed upward to drive the piston 3-8 to slide in the regulating pipe 1-2. At this time, the piston 3-8 is located above the air inlet end 1-3. The exhaust gas entering through the air inlet end 1-3 enters the wind wheel box 4-1 through the air inlet end 3 4-5 and is located below the partition 4-2. The partition 4-2 plays a role in blocking the exhaust gas. Then the exhaust gas flows back to the air outlet end 1-1 through the air outlet end 3 4-6 to prevent the exhaust gas from leaking. The lower rod 3-7 moves upward to drive the collection cover 3-1 to press against the limit ring 3 2-5 for sealing. At the same time, the sealing plate 3-4 is driven to press against the limit ring 2-3 for sealing through the linkage rod 3-3. The sealing plate 3-4 moves through the sealing plug support 3-5 to drive the sealing plug 3-6 to move and separate from the fixed ring air inlet hole 2-2. The sealing plate 3-4 moves to drive the upper rod 3-9 to move through the sealing plug support 3-5. The sealing gasket 3-10 is pressed against the sealed air outlet end 1-1, and the exhaust gas entering the wind wheel box 4-1 drives the wind wheel 4-7 at the lower end to rotate, and at the same time drives the wind wheel 4-7 at the upper end to rotate through the shaft rod. The wind wheel 4-7 at the upper end rotates to suck in air through the air inlet end 4-3, and then enters the outer shell 1 through the air outlet end 4-4. After entering the outer shell 1, the air enters the fixed ring 2-1 through the fixed ring air inlet hole 2-2, blows off the impurities on the filter screen 2-6, and drives the impurities through the collecting cover 3-1 and the collecting cover pipe 3-2 for discharge and collection. The above method can play a role in sealing the impurities when cleaning impurities, avoiding secondary pollution caused by impurity leakage. The collecting cover pipe 3-2 is provided with a valve, and the valve is closed when there is no need to clean the impurities. When the impurities on the filter screen 2-6 are cleaned, the lower rod 3-7 is pulled to reset and the metering work can be continued.

[0043] The sealing plate 3-4 and the sealing plug 3-6 are arranged to prevent air leakage.
