After the waste gas enters, it will contact the filter screen inside the air inlet pipe. Then the filter screen will filter the impurities in the waste gas. Then it enters the desulfurization and denitration tower main body through the gas transmission pipe for subsequent treatment. As the waste gas is continuously conveyed, more and more impurities will be adsorbed on the surface of the filter screen. When it is blocked to a certain extent, the air permeability efficiency of the filter screen decreases, and the waste gas speed will cause pressure on the installation ring and the filter screen. Then stretch the spring and push it inwards. When the installation ring contacts the touch button on the inner wall of the gas transmission pipe, the touch button will trigger the alarm to sound, thus reminding the staff that the filter screen is blocked and cleaning it in time. When cleaning, only need to start the electric push rod, and then make the electric push rod drive the air inlet pipe away from the gas transmission pipe through the pushing ring, so that the filter screen is exposed, and then clean it.

After that, the gas first enters the detection box through the pipeline. Then, the gas detector in the detection box detects the gas. When the gas is qualified, the first solenoid valve is opened and the second solenoid valve is closed, so that the gas is directly discharged from the exhaust pipe. When the gas is unqualified, the controller will close the first solenoid valve and open the second solenoid valve. Then, the gas is re-entered into the main body of the desulfurization and denitration tower through the return pipe for secondary treatment. This method is simple to operate and is convenient to improve the treatment accuracy of the gas.

After the waste gas enters, it will contact the filter screen inside the air inlet pipe. Then the filter screen will filter the impurities in the waste gas, and then enter the main body of the desulfurization and denitration tower through the air inlet pipe for subsequent treatment. As the waste gas is continuously transported, more and more impurities will be adsorbed on the surface of the filter screen. When the blockage reaches a certain level, the air permeability efficiency of the filter screen decreases, and the waste gas speed will exert pressure on the mounting ring and the filter screen, and then stretch the spring to push inward. When the mounting ring contacts the touch button on the inner wall of the air inlet pipe, the touch button will trigger the alarm to sound, thus reminding the staff that the filter screen is blocked and needs to be cleaned in time. When cleaning, only need to start the electric push rod, and then make the electric push rod drive the air inlet pipe away from the air inlet pipe through the push ring, so that the filter screen is exposed, and then clean it.

Then the gas detector in the detection box detects the gas. When the gas is qualified, the first solenoid valve is opened and the second solenoid valve is closed, so that the gas is directly discharged from the exhaust pipe. When the gas is unqualified, the controller will close the first solenoid valve and open the second solenoid valve, and then make the gas enter the main body of the desulfurization and denitration tower again through the return pipe for secondary treatment.

After the exhaust gas enters, it will contact the intake pipe 9, and then the filter 21 will filter the impurities in the exhaust gas, and then enter the desulfurization and denitrification tower body through the air pipe 13 for subsequent treatment. As the exhaust gas is continuously transported, more and more impurities on the surface of the filter 21 will be adsorbed. When it is blocked to a certain extent, the air permeability of the filter 21 is reduced, and the exhaust gas speed will cause pressure on the mounting ring 20 and the filter 21. Then the tension spring 18 is pushed inward. When the mounting ring 20 contacts the touch button 22 on the inner wall of the air pipe 13, the touch button 22 will trigger the alarm 23 to sound, thereby reminding the staff that the filter 21 is blocked and cleaned in time.

As the waste gas is continuously conveyed, more and more impurities will be adsorbed on the surface of the filter screen 21. When it is blocked to a certain extent, the air permeability efficiency of the filter screen 21 decreases, and the waste gas speed will cause pressure on the mounting ring 20 and the filter screen 21.

During cleaning, only need to start the electric push rod 11, and then the electric push rod 11 drives the intake pipe 9 away from the delivery pipe 13 through the pushing ring 10, so that the filter screen 21 is exposed, and then it can be cleaned. This method is simple to operate, convenient to detect the blockage of the filter screen 21 in time, and convenient to clean it. After the waste gas enters the desulfurization and denitrification tower body 1 for treatment, the gas first enters the detection box 3 through the pipeline. Then, the gas detector 24 in the detection box 3 detects the gas. When the gas is qualified, the first solenoid valve 25 is opened and the second solenoid valve 6 is closed, so that the gas is directly discharged from the exhaust pipe 4. When the gas is unqualified, the controller 7 will close the first solenoid valve 25 and open the second solenoid valve 6, and then the gas enters the desulfurization and denitrification tower body 1 again through the return pipe 8 for secondary treatment. This method is simple to operate and convenient to improve the treatment accuracy of the gas. By setting the dirt storage pipe 16, it is convenient to collect the impurities filtered by the filter screen 21.
