[0040] A specific application of this embodiment is as follows: The waste gas enters the interior of the first treatment tank 2 from the intake pipe 3. The first motor 81 is started, and the output shaft of the first motor 81 rotates the reciprocating lead screw 82. The rotation of the reciprocating lead screw 82 causes the reciprocating nut 83 to move. The movement of the reciprocating nut 83 drives the spring 84 to move. The movement of the spring 84 drives the scraping rod 85 to move. The movement of the scraping rod 85 drives the scraping block 86 to move. The movement of the scraping rod 85 drives the connecting block 87 to move. The movement of the connecting block 87 drives the first convex block 88 to move. When the first convex block 88 moves, it will contact the second convex block 810, thereby compressing the spring 84. When the first convex block 88 does not contact the second convex block 810, the spring 84 will rebound, so as to better scrape off the particulate matter on the surfaces of the scraping rod 85 and the scraping block 86, ensuring that the waste gas can pass through the filter screen 811 normally.

[0041] The waste gas enters the third treatment tank 7. The electric telescopic rod 93 is started, and the telescopic end of the electric telescopic rod 93 squeezes the airbag 94. After being squeezed, the airbag 94 will generate gas, and the gas will enter the interior of the liquid storage tank 97 through the intake pipe 96, so that the catalytic reductant in the liquid storage tank 97 enters the liquid outlet block 99 through the liquid outlet pipe 98, and finally enters the interior of the second treatment tank 5 from the liquid outlet block 99, and then removes the nitrogen oxides in the waste gas, improving the air quality of the surrounding area, helping to protect human health and the ecological environment. The remaining waste gas enters the interior of the third treatment tank 7. Water enters the water storage tank 102 from the intake pipe 103, and then the heat energy of the remaining waste gas starts the heating component 101 to heat the water storage tank 102, thereby generating water vapor. The second motor 105 is started, and the output shaft of the second motor 105 drives the reciprocating lead screw 106 to rotate. The rotation of the reciprocating lead screw 106 drives the reciprocating nut 107 to move. The movement of the reciprocating nut 107 drives the connecting rod 108 to move. The movement of the connecting rod 108 drives the guide plate 109 to guide, thereby improving the energy utilization efficiency, reducing the dependence on traditional energy, and reducing the energy cost. The control system has two modes: automatic and manual, and can realize the automatic control of the operation of the fan, water pump, acid adding pump and spraying system, and can be interlocked with the core making machine. Sound and light alarms are set at the main operating parts. The control display includes the water level, acid level, acidity display, and failures of the circulation pump and acid adding pump. There are also automatic water addition, acid addition, and automatic detection, providing a safe and reliable acid adding pipeline and acid adding inlet for easy operation. The acid discharge pipeline from the installation platform to the ground is convenient for acid liquid discharge.
