[0053] The outer surface of the inner shell 21 is provided with a ring block 22 at the position of the ring groove 19, the ring block 22 is matched in size with the ring groove 19, so that the ring block 22 can rotate transversely in the ring groove 19, an inclined surface 23 is formed on the upper end surface of the inner shell 21, the angle of the inclined surface 23 is arranged between 45-60°, and a plurality of arc-shaped guide arc blocks 24 are fixedly arranged on the surface of the inclined surface 23, a temporary storage cavity 25 is formed in the center bottom of the inclined surface 23 of the inner shell 21, the temporary storage cavity 25 is overall conical, the inclined surface formed by the temporary storage cavity 25 is consistent with the angle of the inclined surface 23, and the direction is opposite, a plurality of spray holes 26 are formed in the bottom of the temporary storage cavity 25, the plurality of spray holes 26 are overall conical, and the bottom width of the spray hole 26 is larger, the part of the inlet pipe 11 in the flow cavity 14 is arranged as a necked spray head 32, and the necked spray head 32 is overall arranged above one side of the guide arc block 24, and the spray port end of the necked spray head 32 is aligned with the arc surface of the guide arc block 24.

[0054] It should be noted that the upper end surface of the ring block 22 is provided with auxiliary port two 27 at the position of the plurality of auxiliary port one 20, and the auxiliary port one 20 is consistent in width, and is filled with polyurethane sponge material, which has good mist filtering property and corrosion resistance, and a support cone rod 28 is fixedly arranged at the bottom of the spray hole 26 in the flow cavity 14, the top of the support cone rod 28 is arranged as an inverted cone, the bottom of the support cone rod 28 is arranged as a rod, and the rod is inserted through the two spray layers 16, the filling layer 30 and the opening at the bottom of the spray packing tower 7, and a cross-shaped support is fixedly arranged at the fixed position to improve the stability, and a liquid storage groove 29 is formed in the inverted cone top of the support cone rod 28, which intercepts the spray hole 26 at the middle part.

[0055] The implementation principle of example 2 is that the gas introduced from the shunt buffer tank 6 is input into the spray packing tower 7, so as to be located at the bottom of the flow cavity 14, at this time, the personnel extracts the external filtrate by the microcomputer control circulating mechanism 10, and the filtrate is transported into the flow cavity 14 by the inlet pipe 11, in the transportation process, the filtrate receives the thrust of the circulating mechanism 10 and the necked spray head 32 to reduce the output end, so as to increase the spray speed of the filtrate, the filtrate sprayed by the necked spray head 32 impacts the arc surface of the guide arc block 24, so as to receive the thrust by the guide arc block 24, and drive the inner shell 21 to rotate in the inner surface of the outer ring 18, in the rotating process, when the plurality of auxiliary port two 27 and the auxiliary port one 20 overlap, the port is connected, and the gas on the top of the spray layer 16 is contacted with the sponge in the auxiliary port two 27 and the auxiliary port one 20 to be discharged, so as to form an auxiliary filtering effect.

[0056] The filtrate flows into the temporary storage cavity 25 from the inclined surface 23 and is sprayed downward to the top of the spray layer 16 through the plurality of spray holes 26. During the spraying process, the reduced discharge of the filtrate through the reduced hole at the top of the spray hole 26 and the increased discharge of the filtrate through the enlarged hole at the bottom of the spray hole 26 increase the range of the filtrate discharge. The overall rotation of the inner shell 21 causes the filtrate to be dispersed twice, thereby increasing the range of the filtrate discharge. The filtrate located in the central portion first contacts the support cone rod 28, thereby filling into the liquid storage groove 29. When the liquid storage groove 29 is filled, the filtrate flows downward from the conical portion at the top of the support cone rod 28. The remaining filtrate is sprayed downward into the spray layer 16 to contact the high-temperature waste gas to form cooling. The high-temperature waste gas flowing upward from the spray layer 16 first contacts the conical lower surface of the support cone rod 28, thereby receiving the temperature conducted from the filtrate in the liquid storage groove 29 to form condensation. The condensation reduces the mist coefficient in the waste gas. The liquid generated by the condensation flows downward along the rod portion of the support cone rod 28 into the discharge pipeline 9.

[0057] Then, the high-temperature waste gas contacts the conical surface of the support cone rod 28, which is guided to flow upward by the inclined surface. Part of the waste gas flows out through the through hole formed by the auxiliary port one 20 and the auxiliary port two 27. The remaining waste gas is mixed with the filtrate again through the spray hole 26 and is discharged upward by the inclined surface 23.

[0059] Reference Figures 1-8 A method comprising the steps of:

[0060] S01, The high-temperature waste gas discharged from the drying lines of the north-south two lines is transported into the inner furnace section chimney 1 through the pipeline, and then discharged from the output end of the furnace section chimney 1. The waste gas of the north-south two lines is uniformly transported into the mixing buffer tank 3 through a plurality of pipelines, thereby adjusting the flow of the waste gas and reducing the flow rate. During the transportation process of the furnace section chimney 1, the microcomputer controls a plurality of electrically adjusted dampers 2 to open and close the pipeline, thereby forming automatic control of the flow transportation and avoiding the positive pressure fire extinguishing phenomenon caused by pressure imbalance. Then, the mixing buffer tank 3 is provided with output ends corresponding to the north-south two lines on both sides, and a plurality of pipelines are connected at the output end positions to divide the internal waste gas. A plurality of corresponding heat exchangers 4 are also connected. The waste gas enters the heat exchanger 4 to contact the filtrate, thereby being preliminarily cooled. Then, the waste gas is drawn into the shunt buffer tank 6 by the induced draft fan 5 to flow again. Finally, the waste gas is transported into the spray packing tower 7 from the shunt buffer tank 6 to perform the mist removal process.

[0061] S02, the circulating mechanism 10 interfaces with the external water supply mechanism, thereby drawing the filtrate into and delivering it through the inlet conduit 11 into the flow chamber 14, receiving compression from the converging jet 32 during the input process to increase the flow rate impact force, and as the filtrate is inputted, the guide arc block 24 is impacted to form a thrust force, causing the inner housing 21 to rotate, and the filtrate flows into the temporary storage chamber 25 from the inclined surface 23 and is sprayed downward from the plurality of spray holes 26, cooperating with the rotation of the inner housing 21 to cause the sprayed filtrate to diffuse, thereby increasing the coverage range, wherein the filtrate within the range of the liquid storage groove 29 fills the liquid storage groove 29, and when the liquid storage groove 29 is filled, it overflows along the top surface of the support cone rod 28 and flows downward, and the remaining filtrate is sprayed downward to be delivered into the spray layer 16.

[0062] S03, the exhaust gas entering the shunt buffer tank 6 is delivered into the spray filler tower 7 and flows upward as a whole at the bottom of the flow chamber 14, first the exhaust gas passes through the spray layer 16 and contacts the filtrate in the internal hole to form preliminary demisting, and then the exhaust gas flows upward from the top of the spray layer 16 and contacts the conical bottom surface of the support cone rod 28, thereby receiving the low-temperature filtrate in the liquid storage groove 29 to form condensation, generating water droplets attached to the conical bottom surface of the support cone rod 28, and flowing downward along the rod of the support cone rod 28 and being discharged into the outlet conduit 9, and then the condensed exhaust gas flows upward through the plurality of spray holes 26 to the temporary storage chamber 25 and fully contacts the filtrate, forming a cooling and demisting effect, and finally passing through the plurality of activated carbon layers 15 to reduce the content of flue gas and water vapor, and being discharged to the outside by the outlet chimney 8.
