[0042] Specifically, the threshing and concentrating component 2 includes a conical cylinder 201 connected to the inner side of the bracket 1, and a particle removal chamber 202 is connected to the conical cylinder 201, and a guide blade 203 is rotatably connected in the particle removal chamber 202. The outer wall of the particle removal chamber 202 is connected to the exhaust gas inlet pipe 204 corresponding to the guide blade 203 in the tangential direction. The exhaust gas quickly flows into the particle removal chamber 202 through the exhaust gas inlet pipe 204, and the exhaust gas flow is strongly rotated by the guiding effect of the guide blade 203. The spray hood 301 of the exhaust gas spray component 3 is connected to the particle removal chamber 202, and a rotating disk 302 is rotatably connected in the spray hood 301. An annular groove 306 is opened on the circumferential surface of the rotating disk 302, and a mesh wheel ring 303 is embedded in the annular groove 306. The outer wall of the spray hood 301 corresponds to the mesh wheel ring 303 along the tangential direction. 03 is connected with a medicine liquid introduction pipe A305, which is used to drive the rotating disk 302 to rotate through the mesh wheel ring 303. A plurality of spray holes 304 in a circular array are provided at the bottom of the rotating disk 302. A plurality of exhaust pipes 7 are clamped on the rotating disk 302, and the waste gas flowed to the exhaust pipe 9 after being processed under the rotating disk 302. A plurality of medicine liquid atomizing components 4 are clamped in the plurality of spray holes 304, respectively. The medicine liquid atomizing components 4 include a plurality of medicine liquid atomizing parts 401 respectively embedded in the plurality of spray holes 304. An elastic connecting part 402 is sleeved in the port at the other end of the medicine liquid atomizing part 401. The ports at the other ends of the plurality of elastic connecting parts 402 are rotatably connected with the same linkage rod 403. A sleeve 404 is sleeved on the end of the linkage rod 403. The other end of the sleeve 404 is connected to the inner wall of the mesh wheel ring 303.

[0043] A supporting ring B405 is clamped on the linkage rod 403, and a supporting spring 406 is connected to the supporting ring B405. The supporting ring B405 is elastically supported and connected to the sleeve 404 through the supporting spring 406. A counterweight block 407 is also clamped on the linkage rod 403. The liquid atomizing member 401 includes an atomizing nozzle 4013 embedded in the spray hole 304, and an elastic sealing pad is filled between the atomizing nozzle 4013 and the spray hole 304. The atomizing nozzle 4013 is connected to a spray barrel 4011, and the outer wall of the spray barrel 4011 is provided with a plurality of liquid inlet ports 4012 in a circular array. The elastic connecting member 402 includes a movable shaft 4021 sleeved in another port of the spray barrel 4011, and the port at the other end of the movable shaft 4021 is rotatably connected to the linkage rod 403;

[0045] The specific implementation method is as follows: the liquid medicine flowing to the inside through the mesh wheel ring 303 enters the spray barrel 4011 through the liquid medicine inlet 4012, and is finally sprayed out through the atomizing nozzle 4013. The rotating disk 302 rotates, and the protrusions at the bottom thereof will play a role in disturbing the flow, thereby driving the liquid medicine sprayed out through the multiple groups of atomizing nozzles 4013 to rotate and flow. The rotation speed of the guide blade 203 is proportional to the power carried by the exhaust gas entering the particle removal chamber 202 through the exhaust gas inlet pipe 204, that is, the faster the exhaust gas flow rate, the faster the rotation speed of the guide blade 203, and the lower the flow rate of the exhaust gas, the lower the rotation speed of the guide blade 203. The rotating disk 302 is counterweighted during the rotation process. 407 will be affected by the centrifugal force, and the counterweight block 407 drives the linkage rod 403 to retract in the sleeve 404, and squeezes the support spring 406 to make it elastically deformed. During this process, the linkage rod 403 rotates on the inner side of the end of the movable shaft 4021. Driven by the linkage rod 403, the movable shaft 4021 stretches in the spray barrel 4011 and pulls the movable spring 4023 to stretch. During this process, the movable shaft 4021 also drives the atomizing nozzle 4013 to tilt through the elastic sealing sheet through the spray barrel 4011. The faster the rotation speed of the rotating disk 302, the greater the centrifugal force acting on the counterweight block 407.

[0046] Specifically, an adapter sleeve 6 is clamped at the axis of the rotating disk 302, and a transmission assembly 8 is embedded inside the adapter sleeve 6. The transmission assembly 8 includes an outer gear ring 801 clamped in another end of the adapter sleeve 6;

[0047] The inner side of the adapter sleeve 6 is provided with a transmission shaft 802, the end of the transmission shaft 802 is connected to the guide blade 203, the other end of the transmission shaft 802 is clamped with an inner gear ring 804, a transmission gear 803 is meshed between the inner gear ring 804 and the outer gear ring 801, and the transmission gear 803 is rotatably connected to the inner top of the spray hood 301 through the gear shaft.

[0048] The specific implementation method is as follows: the guide blade 203 drives the transmission shaft 802 to rotate during rapid rotation, the transmission shaft 802 drives the inner gear ring 804, the inner gear ring 804 drives the outer gear ring 801 to rotate in the opposite direction through the transmission gear 803, the outer gear ring 801 rotates the rotating disk 302 through the adapter sleeve 6, the rotation direction of the rotating disk 302 is opposite to the rotation direction of the guide blade 203, the rotating disk 302 also drives the mesh wheel ring 303 to rotate during the rotation process, the rotation direction of the mesh wheel ring 303 is opposite to the flow direction of the liquid introduced through the liquid introduction pipe A305.

[0049] Specifically, a liquid medicine introduction component 12 is installed on the bracket 1 corresponding to the liquid medicine introduction pipe A305, and the liquid medicine introduction component 12 includes a liquid medicine introduction pump 1203 installed on the bracket 1, the output port of the liquid medicine introduction pump 1203 is connected to the liquid medicine introduction pipe B1201, the other end of the liquid medicine introduction pipe B1201 is connected to the liquid medicine introduction pipe A305, and the input port of the liquid medicine introduction pump 1203 is connected to the liquid medicine introduction pipe C1202.

[0050] The specific implementation method is as follows: in the process of removing particulate matter from the exhaust gas flowing into multiple exhaust pipes 7, the operation of the liquid introduction pump 1203 is controlled. The liquid introduction pump 1203 draws the liquid medicine in the liquid storage pool through the liquid introduction pipe C1202, and discharges it into the liquid introduction pipe A305 through the liquid introduction pipe B1201.

[0051] Working principle, when using:

[0052] Select appropriate liquid medicine according to the type of waste gas to be treated, and sink the end of the liquid medicine introduction pipe C1202 into the selected liquid medicine storage tank;

[0053] The waste gas to be treated quickly enters the particle removal chamber 202 through the waste gas inlet pipe 204. When the waste gas containing particulate matter enters the particle removal chamber 202 along the axial direction, the waste gas to be treated is strongly rotated by the guide vane 203. The waste gas to be treated spirally enters the conical cylinder 201 along the cylinder of the particle removal chamber 202. The particles with high density are thrown to the inner wall of the particle removal chamber 202 and the conical cylinder 201 under the action of centrifugal force, and fall and flow out along the inner wall of the conical cylinder 201 under the action of gravity. The rotating waste gas to be treated shrinks and flows toward the center in the particle removal chamber 202, forming a secondary vortex upwards and flowing to the discharge pipe 9 through multiple exhaust pipes 7, and then flows out through the top outlet of the exhaust pipe 7. The flue gas detection module 10 is used to detect the waste gas after treatment, and the concentration of the medicine solution is changed in time.

[0054] In the process of removing particulate matter from the exhaust gas flowing to multiple exhaust pipes 7, the liquid medicine introduction pump 1203 is controlled to operate. The liquid medicine introduction pump 1203 draws the liquid medicine in the liquid medicine storage pool through the liquid medicine introduction pipe C1202, and discharges it into the liquid medicine introduction pipe A305 through the liquid medicine introduction pipe B1201, and finally discharges it into the spray hood 301 through the liquid medicine introduction pipe A305. When the liquid medicine enters the annular groove 306 along the axial direction, it directly acts on the mesh wheel ring 303. During the rapid rotation of the guide blade 203, the transmission shaft 802 is driven to rotate, and the transmission shaft 802 drives the inner gear ring 804. The inner gear ring 804 drives the outer gear ring 801 to rotate in the opposite direction through the transmission gear 803. The outer gear ring 801 rotates the rotating disk 302 through the adapter sleeve 6. The rotation direction is opposite to that of the guide blade 203. The rotating disk 302 will also drive the mesh wheel ring 303 to rotate during the rotation. The rotation direction of the mesh wheel ring 303 is opposite to the flow direction of the liquid medicine introduced through the liquid medicine introduction pipe A305. Therefore, when the liquid medicine enters the annular groove 306 and acts on the mesh wheel ring 303, on the one hand, the mesh wheel ring 303 can filter the liquid medicine to prevent the liquid medicine from precipitating during the long-distance flow and transmission in the pipeline and causing the atomizing nozzle 4013 to be blocked. On the other hand, when the liquid medicine is flushed on the mesh wheel ring 303, the mesh wheel ring 303 can destroy the liquid medicine precipitate, thereby re-dissolving the precipitate, ensuring the concentration of the liquid medicine, so that the harmful substances in the exhaust gas can be fully purified by the liquid medicine.

[0055] The liquid medicine flowing to the inside through the mesh ring 303 enters the spray barrel 4011 through the liquid medicine inlet 4012, and is finally sprayed out through the atomizing nozzle 4013. The rotating disk 302 rotates the protrusions at the bottom to play a role of disturbing the flow, and then drives the liquid medicine sprayed by the multiple groups of atomizing nozzles 4013 to rotate and flow. The liquid medicine flowing downward and the exhaust gas flowing upward in the opposite direction are counteracted, so that the spray range of the liquid medicine is expanded, and the contact area and contact time of the exhaust gas and the liquid medicine are increased, thereby improving the exhaust gas treatment efficiency, and at the same time, improving the exhaust gas treatment quality, reducing the exhaust gas treatment pressure in the spray hood 301, and achieving the effect of reducing the volume of the single-seat spray hood 301;

[0056] The rotation speed of the guide blade 203 is proportional to the power carried by the exhaust gas entering the particle removal chamber 202 through the exhaust gas inlet pipe 204, that is, the faster the exhaust gas flow rate, the faster the rotation speed of the guide blade 203, and the lower the flow rate of the exhaust gas, the lower the rotation speed of the guide blade 203. During the rotation of the rotating disk 302, the counterweight block 407 will be affected by the centrifugal force. The counterweight block 407 drives the linkage rod 403 to retract in the sleeve 404 and squeezes the support spring 406 to make it elastically deformed. During this process, the linkage rod 403 rotates on the inner side of the end of the movable shaft 4021. Driven by the linkage rod 403, the movable shaft 4021 extends in the spray barrel 4011 and pulls the movable spring 4023 to extend. During this process, the movable shaft 4021 also drives the atomizing nozzle 4013 to tilt through the elastic sealing sheet through the spray barrel 4011. Due to the rotation speed of the rotating disk 302 The faster the centrifugal force acts on the counterweight 407, the greater the inclination angle of the atomizing nozzle 4013 increases, the concentration of the liquid medicine at the axis center in the spray hood 301 increases, and decreases instead. The rotating waste gas to be treated shrinks in the particulate removal chamber 202 and flows toward the center, forming a secondary vortex upward to mix with the liquid medicine. The faster the flow rate of the waste gas to be treated flows toward the center, the higher the shrinkage rate. The waste gas treatment efficiency is improved by adaptively adjusting the molar ratio of the liquid medicine at the axis center in the spray hood 301 and the waste gas therein, and the centrifugal granulation treatment is combined with the liquid medicine treatment. Through the organic combination of multiple treatment methods, the waste gas treatment effect is effectively improved. The precipitate produced by the mixture of the liquid medicine and the waste gas will be thrown to the inner wall of the spray hood 301 and the particulate removal chamber 202 under the action of centrifugal force, and finally fall and flow out along the inner wall of the conical cylinder 201 under the action of gravity, reducing the generation of scale, thereby avoiding corrosion to the adsorption concentration oxidation treatment device as a whole.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
