When the tail gas descends and passes through a plurality of separation plates, the separation plates will directly throw larger particles in the tail gas into an annular collection box through an annular discharge pipe. When the elastic filter plate vibrates, the impurity particles on the elastic filter plate are shaken into the air. When the impurity particles in the air contact the rotating separation plate, they will be thrown into the annular collection box by the separation plate under the action of centrifugal force, effectively avoiding the elastic filter plate from being blocked by excessive accumulation of impurities, and further improving the impurity removal effect.

[0022] (3) The present invention provides a heat transfer oil furnace tail gas treatment device. After the tail gas passes through the elastic filter plate, it will enter the top of the vanadium titanate porous round block. At this time, the urea solution in the hollow groove will be sprayed out from the liquid outlet during the rotation process, so that the solution is stratified to increase the contact probability between the urea solution and the tail gas. In the process of the movable plate continuously rising and falling, the two triangular ring blocks will be driven to move up and down. When the triangular ring block moves up, the urea solution will be sprayed onto the lower inclined surface of the triangular ring block and rebound. When the triangular ring block moves down, the urea solution will be sprayed onto the upper inclined surface of the triangular ring block and rebound. The triangular ring block moves up and down continuously, so that the rebounded solution will cover the entire contact area, so that the tail gas is fully in contact with the urea solution. The tail gas that contacts the urea solution will enter the vanadium titanate porous round block, so that the nitrogen dioxide in the tail gas reacts to generate harmless nitrogen and water.

When the trapezoidal block 1 202 rotates, it will contact the trapezoidal block 2 203. When the trapezoidal block 203 is thrust, it will drive the movable plate 103 to rise. As the trapezoidal block 1 202 continuously leaves the trapezoidal block 2 203, the vibrating semicircular block 108 will continuously hit the elastic filter plate 102.

The triangular ring block 503 continuously moves up and down, and the rebounded solution covers the entire contact area, so that the exhaust gas is fully in contact with the urea solution. The exhaust gas that contacts the urea solution enters the vanadium titanate porous circular block 502, causing the nitrogen dioxide in the exhaust gas to react to generate harmless nitrogen and water.

[0047] like Figure 5 As shown, a separation mechanism 6 is provided on the rotating shaft 101 , and the separation mechanism 6 includes a circular separation plate 601 fixedly sleeved on the rotating shaft 101 , and a plurality of inclined holes 602 are opened on the circular separation plate 601 .

[0048] Attached to the surface of the circular separation plate 601 and the inclined hole 602, the rotation of the rotating shaft 101 will drive the circular separation plate 601 to rotate.

[0052] S1: Start the driving motor 703, the driving motor 703 drives the fan 701 to rotate through the rotating shaft 702, the fan 701 generates a suction force to inhale the exhaust gas through the intake pipe 302, when the exhaust gas enters the intake pipe 302, it will push the several transmission blades 301 on the rotating shaft 101 to rotate, the transmission blades 301 drive the rotating shaft 101 to rotate, the rotating shaft 101 drives the circular plate 201 to rotate, the circular plate 201 drives several trapezoidal blocks 1 202 to rotate, when the trapezoidal block 1 202 rotates, it will contact the trapezoidal block 2 203, when the trapezoidal block 203 is subjected to the thrust, it will drive the movable plate 103 to rise, the movable plate 103 drives the vibration rod 107 to rise, the vibration rod 107 drives the vibration semicircular block 1 08 will hit the elastic filter plate 102. When the exhaust gas passes through the elastic filter plate 102, the particle impurities will be filtered onto the elastic filter plate 102. The impact of the vibrating semicircular block 108 will vibrate and deform the elastic filter plate 102. As the trapezoidal block 1 202 continuously leaves the trapezoidal block 2 203, the vibrating semicircular block 108 will continuously hit the elastic filter plate 102. Under the action of vibration, the impurity particles on the elastic filter plate 102 are prevented from clogging the filter holes of the elastic filter plate 102. During the process of rising and falling, the movable plate 103 will be damped by a number of vibration springs 106 to effectively reduce noise. At the same time, the elastic force of the vibration spring 106 will also increase the moving speed of the movable plate 103 during the lifting process.

[0053] S2: When the exhaust gas descends and passes through a plurality of separation plates 304, the separation plates 304 will directly throw larger particles in the exhaust gas into the annular collection box 306 through the annular discharge pipe 305. When the elastic filter plate 102 vibrates, the impurity particles on the elastic filter plate 102 are shaken into the air. When the impurity particles in the air contact the rotating separation plates 304, they will be thrown into the annular collection box 306 by the separation plates 304 under the action of centrifugal force, effectively avoiding the accumulation of impurities on the elastic filter plate 102 and causing blockage;

[0054] S3: After the tail gas passes through the elastic filter plate 102, it will enter the top of the vanadium titanate porous round block 502. At this time, the urea solution in the hollow groove 403 will be sprayed out from the liquid outlet 404 during the rotation process, so that the solution is stratified to increase the contact probability of the urea solution and the tail gas. In the process of the movable plate 103 constantly rising and falling, the two triangular ring blocks 503 will be driven to move up and down. When the triangular ring block 503 moves up, the urea solution will be sprayed onto the lower inclined surface of the triangular ring block 503 and rebound. When the triangular ring block 503 moves down, the urea solution will be sprayed onto the upper inclined surface of the triangular ring block 503 and rebound. The triangular ring block 503 moves up and down continuously, so that the rebounded solution will cover the entire contact area, so that the tail gas is fully in contact with the urea solution. The tail gas that contacts the urea solution will enter the vanadium titanate porous round block 502, so that the nitrogen dioxide in the tail gas reacts to generate harmless nitrogen and water;

[0055] S4: Under the suction action of the fan 701, the generated nitrogen will be discharged from the air outlet 704, and the generated water will be in the form of water droplets, attached to the surface of the circular separation plate 601 and the inclined hole 602. The rotation of the rotating shaft 101 will drive the circular separation plate 601 to rotate. When the circular separation plate 601 rotates, centrifugal force is generated. The centrifugal force will throw the water droplets on the surface of the circular separation plate 601 and the inclined hole 602 onto the inner wall of the processing box 1. The water droplets thrown onto the inner wall of the processing box 1 will quickly gather into water, which is convenient for collecting the water.

4. The method for treating tail gas from a thermal oil furnace according to claim 3, characterized in that: The steps are as follows: S1: starting the driving motor (703), the driving motor (703) drives the fan (701) to rotate via the rotating shaft (702), the fan (701) generates a suction force to suck the exhaust gas through the intake pipe (302), when the exhaust gas enters the intake pipe (302), it drives a plurality of transmission blades (301) on the rotating shaft (101) to rotate, the transmission blades (301) drive the rotating shaft (101) to rotate, the rotating shaft (101) drives the circular plate (201) to rotate, the circular plate (201) drives a plurality of trapezoidal blocks (202) to rotate, when the trapezoidal block (202) rotates, it contacts the trapezoidal block (203), when the trapezoidal block (203) is subjected to a thrust, it drives the movable plate (103) to rise, the movable plate (103) drives the vibration rod (107) to rise, the vibration rod (107) drives The vibrating semicircular block (108) will hit the elastic filter plate (102). When the exhaust gas passes through the elastic filter plate (102), the particle impurities will be filtered onto the elastic filter plate (102). The impact of the vibrating semicircular block (108) will cause the elastic filter plate (102) to vibrate and deform. As the trapezoidal block 1 (202) continuously leaves the trapezoidal block 2 (203), the vibrating semicircular block (108) will continuously hit the elastic filter plate (102). Under the action of vibration, the impurity particles on the elastic filter plate (102) are prevented from clogging the filter holes of the elastic filter plate (102). During the process of rising and falling, the movable plate (103) will be damped by a plurality of vibrating springs (106) to effectively reduce noise. At the same time, the elastic force of the vibrating springs (106) will also increase the moving speed of the movable plate (103) during the lifting process. S2: When the exhaust gas descends and passes through a plurality of separation plates (304), the separation plates (304) will directly throw larger particles in the exhaust gas through the annular discharge pipe (305) into the annular collection box (306). When the elastic filter plate (102) vibrates, the impurity particles on the elastic filter plate (102) are shaken into the air. When the impurity particles in the air contact the rotating separation plates (304), they are thrown into the annular collection box (306) by the separation plates (304) under the action of centrifugal force, thereby effectively preventing the elastic filter plate (102) from clogging due to excessive accumulation of impurities; S3: After the exhaust gas passes through the elastic filter plate (102), it will enter the top of the vanadium titanate porous round block (502). At this time, the urea solution in the hollow groove (403) will be sprayed out from the liquid outlet (404) during the rotation process, so that the solution is stratified to increase the contact probability between the urea solution and the exhaust gas. In the process of the movable plate (103) continuously rising and falling, the two triangular ring blocks (503) will be driven to move up and down. When the triangular ring block (503) moves up, the urea solution will be sprayed onto the lower inclined surface of the triangular ring block (503) and rebound. When the triangular ring block (503) moves down, the urea solution will be sprayed onto the upper inclined surface of the triangular ring block (503) and rebound. The triangular ring block (503) moves up and down continuously, so that the rebounded solution will cover the entire contact area, so that the exhaust gas is fully in contact with the urea solution. The exhaust gas that contacts the urea solution will enter the vanadium titanate porous round block (502), so that the nitrogen dioxide in the exhaust gas reacts to generate harmless nitrogen and water. S4: Under the suction effect of the fan (701), the generated nitrogen will be discharged from the air outlet (704), and the generated water will be in the form of water droplets, attached to the surface of the circular separation plate (601) and the inclined hole (602). The rotation of the rotating shaft (101) will drive the circular separation plate (601) to rotate. When the circular separation plate (601) rotates, centrifugal force is generated. The centrifugal force will throw the water droplets on the surface of the circular separation plate (601) and the inclined hole (602) onto the inner wall of the processing box (1). The water droplets thrown onto the inner wall of the processing box (1) will quickly gather into water, making it easy to collect the water.
