Description

Technical Field

[0001] The present invention relates to the technical field of smoke purification, and particularly relates to an industrial smoke purification device and a purification method. Background Art

[0002] A spray tower is a gas purification device that removes pollutants in the gas by spraying liquid, and is widely used in smoke treatment. When the smoke enters the spray tower, the smoke will combine with the falling liquid beads, thereby adsorbing the pollutants in the gas.

[0003] In the field of electric power industry, thermal power plants generate a large amount of heat by burning fossil fuels, and then drive generators to generate electricity through steam turbines. However, when fossil fuels are burned, a large amount of harmful substances such as soot, nitrogen oxides, sulfur oxides, volatile organic compounds, and ozone are produced, which seriously harm the ecological environment. Although existing smoke treatment equipment can effectively reduce the emission of harmful substances, there is still a situation where harmful substances are not fully absorbed by the spray tower and escape into the air. Therefore, there is an urgent need for an industrial smoke purification device and a purification method that can efficiently remove harmful substances in the smoke. Summary of the Invention

The piston cylinder is communicated with a one-way liquid inlet pipe and a one-way liquid outlet pipe. The one-way liquid inlet pipe and the one-way liquid outlet pipe both penetrate through the purification cylinder. A plurality of atomizing nozzles are installed on the one-way liquid outlet pipe.

[0008] Preferably, a sealing shell is fixedly connected between the second partition plate and the partition net. A motor is installed inside the sealing shell. The output shaft of the motor penetrates through the center of the partition net and is fixedly connected to a rotating shaft. A plurality of blades distributed circumferentially are rotatably connected to the circumferential wall of the rotating shaft. A hairspring is rotatably connected between the rotating shaft and the blade.

[0009] Preferably, a sliding shell is slidably connected inside the purification cylinder, and activated carbon is placed inside the sliding shell.

[0010] Preferably, a support frame is fixedly connected to the upper end of the rotating shaft. A first corrugated ring is fixedly connected to the upper part of the support frame. The first corrugated ring is rotatably connected to the purification cylinder. A second corrugated ring is fixedly connected to the bottom of the sliding shell. The second corrugated ring is in movable contact with the purification cylinder. The first corrugated ring and the second corrugated ring cooperate with each other.

[0011] Preferably, a conical hollow block is fixedly connected to the inner top of the purification cylinder. A disc is fixedly connected to the top of the conical hollow block. A plurality of ventilation holes are opened on the disc. The disc is fixedly connected to the purification cylinder. A lead screw is fixedly connected to the center position of the bottom of the disc. A plug is frictionally sleeved on the lead screw. A plurality of ventilation grooves distributed circumferentially are opened on the outer wall of the plug. A piston ring is sleeved on the outer wall of the plug.

[0012] Preferably, a blind hole is opened at the bottom of the conical hollow block. A piezoelectric ceramic is slidably connected inside the blind hole.

The piezoelectric ceramic and the conductive tip frame are electrically connected.

[0013] Preferably, a heat conduction ring is fixedly connected to the top of the compression cone, and the bottom of the heat conduction ring is located inside the compression cone.

[0014] A purification method for an industrial smoke purification device includes the following steps: S1: Connect the external smoke collection device to the intake pipe so that the smoke enters the circular cylinder through the intake pipe. The smoke enters the vortex tube to generate hot smoke and cold smoke. The hot smoke and cold smoke pass through the one-way valve and contact the cleaning liquid. The particulate matter in the smoke is washed away to become waste gas. The waste gas enters the shunt pipe and pushes the extrusion plug upward. The waste gas moves upward along the gap between the shunt pipe and the extrusion plug and collides with the absorption liquid in the diversion pipe to generate fine bubbles. The fine bubbles slowly rise under the guidance of the spiral diversion groove of the shunt pipe, and the waste gas is initially absorbed by the absorption liquid. S2: When the smoke enters the circular cylinder, it blows the impeller to rotate, causing the shaft rod to drive the piston rod to reciprocate in the piston cylinder through the crank, so that the absorption liquid in the purification cylinder enters the piston cylinder along the one-way liquid inlet pipe and sprays out from the atomizing nozzle along the one-way liquid outlet pipe. The absorption liquid is atomized to further absorb the waste gas. S3: The absorption liquid sprayed by the atomizing nozzle falls on the activated carbon. The porous structure of the activated carbon is used to increase the contact area between the absorption liquid and the waste gas, and the activated carbon further absorbs the waste gas. S4: Start the motor. The rotation of the motor drives the blades to stir the absorption liquid through the rotating shaft, so that the concentration of the absorption liquid is kept uniform and the absorption efficiency of the absorption liquid is improved. The rotation of the rotating shaft passes through the support frame, so that the first wave ring drives the activated carbon on the sliding shell to reciprocate through the second wave ring. The excess absorption liquid is shaken off and returns to the second partition to prevent the activated carbon from being blocked. S5: After the waste gas is treated by the absorption liquid at the shunt pipe, during the upward diffusion process of the waste gas, it passes through the activated carbon, is absorbed and treated by the activated carbon and the atomized absorption liquid, and then continues to flow upward. The waste gas accumulates continuously, thus pushing the piston ring upward to compress the second spring. The upward movement of the piston ring pushes the plug to spiral upward along the lead screw. When the second spring is completely compressed, the plug continues to rise so that the waste gas is discharged upward through the ventilation groove of the plug. The second spring releases and pushes the piston ring to impact the piezoelectric ceramic. The piezoelectric ceramic releases an instantaneous high voltage, and the instantaneous high voltage releases an electric spark at the tip of the conductive tip frame to ignite the combustible waste gas in the waste gas. The heat generated during the combustion of the waste gas is absorbed by the heat conduction ring and used to heat the waste gas, completing the treatment of the waste gas.

[0015] The beneficial effects of the present invention are: In the present invention, by setting the atomization unit, the waste gas overcomes the elastic force of the first spring through air pressure, so that the waste gas enters the extrusion shunt pipe and pushes the extrusion plug to compress the first spring. The waste gas flows upward through the gap between the shunt pipe and the extrusion plug and contacts the absorption liquid through the air-permeable plate. Since the gap between the shunt pipe and the extrusion plug is small, based on Bernoulli's principle, the gas in the waste gas will flow at a high speed when passing through this gap, the pressure in the shunt pipe becomes smaller, attracting the absorption liquid to enter the shunt pipe through the diversion pipe. The waste gas collides with the absorption liquid to generate a large number of fine bubbles, improving the absorption efficiency of the absorption liquid for the waste gas.

Detailed implementation manners

[0018] The following further describes the present invention in conjunction with the embodiments shown in the attached drawings.

[0019] Such as Figure 1 , Figure 4As shown in the figure, an industrial smoke purification device includes a purification cylinder 1. One side of the purification cylinder 1 is connected and fixedly attached to an air inlet pipe 2. The air inlet pipe 2 is connected to an external smoke collection device. An exhaust port 101 is opened at the top of the purification cylinder 1. A first liquid inlet 102 and a second liquid inlet 103 are opened on the other side of the purification cylinder 1. A first partition 3 is fixedly attached to the inner bottom of the purification cylinder 1. A second partition 4 and a mesh 5 are fixedly attached near the bottom inside the purification cylinder 1. The internal space of the purification cylinder 1 below the first partition 3 is the bottom cavity. The middle cavity is between the first partition 3 and the second partition 4 inside the purification cylinder 1. A cleaning liquid is contained in the middle cavity inside the purification cylinder 1. The space above the second partition 4 inside the purification cylinder 1 is the top cavity. An absorption liquid is contained in the top cavity inside the purification cylinder 1. The volume of the absorption liquid accounts for one-fourth of the volume of the top cavity of the purification cylinder 1. A circular cylinder 6 is fixedly attached to the top of the first partition 3. The circular cylinder 6 is connected and fixedly attached to the air inlet pipe 2. A number of one-way valves 7 distributed circumferentially up and down are installed on the outer circumferential wall of the circular cylinder 6. The height of the upper one-way valve 7 is slightly lower than the liquid level of the cleaning liquid. A number of atomization units 8 are arranged between the second partition 4 and the mesh 5. The atomization unit 8 includes a shunt pipe 801. A number of shunt pipes 801 are fixedly attached between the second partition 4 and the mesh 5. The bottom of the shunt pipe 801 penetrates through the second partition 4. A spiral diversion groove is opened inside the shunt pipe 801. The spiral diversion groove is used to increase the contact area between the smoke and the absorption liquid and slow down the upward flow time of the smoke. A breathable plate 802 is fixedly attached to the top of the shunt pipe 801. A gap is left at the connection between the top of the shunt pipe 801 and the breathable plate 802 to facilitate the upward flow of the smoke. A pressing plug 803 is slidably connected inside the shunt pipe 801. The spherical surface at the lower end of the pressing plug 803 is in sealing contact with the conical surface inside the shunt pipe 801. A gap is left between the cylindrical surface of the pressing plug 803 and the inner wall of the shunt pipe 801. The pressing plug 803 is made of nickel-iron alloy material and has good corrosion resistance and high temperature resistance to prevent itself from being corroded by the absorption liquid or the smoke. A first spring is connected between the breathable plate 802 and the pressing plug 803. A number of diversion pipes 804 are uniformly communicated on the outer circumference of the shunt pipe 801. The diversion pipes 804 are inclined downward so that the gas will not enter the diversion pipes 804 when passing through the shunt pipe 801.

[0020] As Figure 5 and Figure 6As shown, a vortex tube 9 is fixedly connected to the inner top end of the circular cylinder 6. The vortex tube 9 converts the gas introduced into it into cold gas and hot gas. A plurality of inclined intake holes 901 are circumferentially formed on the outer wall of the vortex tube 9. The axis of the intake hole 901 deviates from the axis of the vortex tube 9, so that when the gas enters the vortex tube 9 through the intake hole 901, a vortex is formed in the vortex tube 9. A hot gas hole 902 is formed at the bottom of the vortex tube 9, and a cold gas hole 903 is formed at the top of the vortex tube 9. A fourth partition plate 10 is fixedly connected to the outer wall of the lower part of the vortex tube 9. The fourth partition plate 10 is fixedly connected to the circular cylinder 6. The fourth partition plate 10 is located between the one-way valves 7 distributed up and down, which is convenient for the fourth partition plate 10 to isolate the hot gas ejected from the hot gas hole 902 from the cold gas ejected from the cold gas hole 903.

[0021] Before using this device, connect the external smoke collection device to the intake pipe 2. The smoke enters the circular cylinder 6 through the intake pipe 2. Subsequently, the smoke enters the vortex tube 9 through the intake hole 901 of the vortex tube 9. Under the guidance of the intake hole 901 of the vortex tube 9, the smoke flows downward in a spiral in the vortex tube 9 to form a vortex. When the smoke enters the vortex tube 9 at a uniform speed, the angular velocity of the smoke at the center of the vortex is higher than that at the edge of the vortex. Due to the different angular velocities, friction occurs between the smoke at the center of the vortex and the smoke at the edge of the vortex. The friction between the smokes slows down the angular velocity of the smoke at the center of the vortex, thereby reducing the energy of the smoke at the center of the vortex and turning it into cold smoke. The angular velocity of the smoke at the edge of the vortex becomes faster, increasing the energy of the smoke at the edge of the vortex. Moreover, the smoke at the edge of the vortex rubs against the inner wall of the vortex tube 9 and turns into hot smoke. The hot smoke is ejected at the hot air hole 902 and enters the circular cylinder 6. The angular momentum of the smoke airflow in the vortex tube 9 is conserved. While the hot smoke flows downward in a spiral, the cold smoke will flow upward in a reverse spiral and be ejected from the cold air hole 903 of the vortex tube 9 into the circular cylinder 6. At this time, the fourth partition 10 separates the hot smoke and the cold smoke in the circular cylinder 6 to prevent the cold smoke from mixing with the hot smoke. The hot smoke at the hot air hole 902 is ejected through the one-way valve 7 at the lower part of the circular cylinder 6 and contacts the cleaning liquid. The heat of the hot smoke is absorbed by the cleaning liquid, increasing the temperature of the cleaning liquid. Thereby, the absorption rate of the cleaning liquid for the soluble waste gas in the smoke is reduced, the service life of the cleaning liquid is improved, and the interference of the soluble waste gas on the cleaning liquid is reduced. The separation of the cold smoke and the hot smoke by the fourth partition 10 enables the cold smoke ejected from the cold air hole 903 to be ejected through the one-way valve 7 at the upper part of the circular cylinder 6 and contact the cleaning liquid. When the smoke contacts the cleaning liquid, the particulate matter in the smoke is adhered to the cleaning liquid, turning the composition of the smoke into waste gas. After the cold smoke and the hot smoke are cleaned by the cleaning liquid and become waste gas, they are mixed at the liquid level of the cleaning liquid. The waste gas accumulates in the middle cavity of the purification cylinder 1, gradually increasing the internal air pressure in the middle cavity of the purification cylinder 1. The waste gas enters the bottom of the shunt pipe 801 and pushes the extrusion plug 803 through the air pressure. The extrusion plug 803 moves upward to compress the first spring. It should be noted that since the lower end of the shunt pipe 801 is located at the bottom of the second partition 4, the spherical surface at the lower end of the extrusion plug 803 is in sealing contact with the conical surface inside the shunt pipe 801, and there is a gap between the cylindrical surface of the extrusion plug 803 and the inner wall of the shunt pipe 801. Therefore, the absorption liquid enters the shunt pipe 801 through the gap between the top of the shunt pipe 801 and the air-permeable plate 802 and fills the gap between the cylindrical surface of the extrusion plug 803 and the inner wall of the shunt pipe 801. When the extrusion plug 803 moves upward, a gap is generated between its lower spherical surface and the shunt pipe 801. The waste gas flows upward in the absorption liquid in the shunt pipe 801 through the gap between the shunt pipe 801 and the extrusion plug 803, and the air pressure prevents the absorption liquid from flowing downward through the gap between the shunt pipe 801 and the extrusion plug 803. The waste gas contacts the absorption liquid through the air-permeable plate 802. Due to the small gap between the shunt pipe 801 and the extrusion plug 803, based on Bernoulli's principle, the gas will flow at a high speed when the waste gas passes through this gap.Reduce the pressure at the connection between the shunt pipe 801 and the diversion pipe 804, so that the absorption liquid flows from the high-pressure area to the low-pressure area, enters the shunt pipe 801 through the diversion pipe 804. The waste gas flowing upward in the shunt pipe 801 collides with the absorption liquid flowing at the diversion pipe 804 to generate a large number of fine bubbles. These bubbles will be guided by the spiral diversion groove of the shunt pipe 801 to rise spirally, slowing down the rising speed of the bubbles, enabling the waste gas in the bubbles to be fully absorbed by the absorption liquid, and improving the efficiency of the absorption liquid in absorbing waste gas.

[0022] As Figure 5 、 Figure 7 As shown, an impeller 11 is rotatably installed at the top inside the circular cylinder 6. The impeller 11 is fixedly connected to the top of the shaft rod 12. At the eccentric part of the lower end of the shaft rod 12, two crank rods 13 are rotatably connected. Both ends of the two crank rods 13 are rotatably connected to a piston rod 14. The outer wall of the piston rod 14 is slidably sleeved with a piston cylinder 15. The piston cylinder 15 is fixedly connected to the purification cylinder 1. The two crank rods 13 share one shaft rod 12, so that the movements of the piston rods 14 in the two piston cylinders 15 are always opposite. The piston cylinder 15 is communicated with a one-way liquid inlet pipe 16 and a one-way liquid outlet pipe 17. Both the one-way liquid inlet pipe 16 and the one-way liquid outlet pipe 17 have the function of one-way flow. Both the one-way liquid inlet pipe 16 and the one-way liquid outlet pipe 17 penetrate through the purification cylinder 1. One end of the one-way liquid inlet pipe 16 away from the piston cylinder 15 is communicated with the lower part of the top cavity of the purification cylinder 1. One end of the one-way liquid outlet pipe 17 away from the piston cylinder 15 is communicated with the upper part of the top cavity of the purification cylinder 1. A plurality of atomizing nozzles 18 facing upward are installed at the end of the top cavity of the one-way liquid outlet pipe 17. The water mist sprayed by the atomizing nozzles 18 is in a disc shape, increasing the contact area between the water mist and the waste gas in the purification cylinder 1.

[0023] When the smoke enters the circular cylinder 6, the smoke blows the impeller 11 to rotate. The rotation of the impeller 11 drives the shaft rod 12 to rotate synchronously. The shaft rod 12 drives the piston rod 14 to reciprocate in the piston cylinder 15 through the crank rod 13. When the volume inside the piston cylinder 15 increases, the pressure inside the piston cylinder 15 decreases. Due to the one-way guiding functions of both the one-way liquid inlet pipe 16 and the one-way liquid outlet pipe 17, the piston cylinder 15 sucks the absorption liquid above the partition net 5 through the one-way liquid inlet pipe 16. When the internal volume of the piston cylinder 15 decreases, the pressure inside the piston cylinder 15 increases. The piston cylinder 15 conveys the absorption liquid to the atomizing nozzles 18 through the one-way liquid outlet pipe 17. The absorption liquid is atomized when sprayed out from the atomizing nozzles 18, increasing the absorption area between the absorption liquid and the waste gas, and improving the efficiency of the absorption liquid in absorbing waste gas. The faster the waste gas blows the impeller 11 to rotate, the faster the frequency of the shaft rod 12 driving the piston rod 14 to reciprocate through the crank rod 13, and the greater the flow rate of the absorption liquid driven by the piston cylinder 15 to be sprayed out from the atomizing nozzles 18, so that the speed of the absorption liquid sprayed out from the atomizing nozzles 18 is balanced with the speed of the waste gas entering the circular cylinder 6, avoiding excessive water mist of the absorption liquid sprayed out from the atomizing nozzles 18 and causing waste.

[0024] As Figure 3 、Figure 8 and Figure 9 As shown in Figure 9 , a sealing shell 19 is fixedly connected between the second partition plate 4 and the partition net 5. A motor 20 is installed inside the sealing shell 19. The output shaft of the motor 20 penetrates through the center of the partition net 5 and is fixedly connected with a rotating shaft 21. A plurality of circumferentially distributed blades 22 are rotatably connected to the circumferential wall of the rotating shaft 21. A clockwork spring is rotatably connected between the rotating shaft 21 and the blades 22. The blades 22 can adjust the inclination angle based on their own rotation speed to prevent a large amount of exhaust gas in the absorption liquid from being stirred and released by the blades 22.

[0025] As Figure 2 and Figure 8 shown in Figure 8 , a sliding shell 23 is slidably connected inside the purification cylinder 1. Activated carbon 24 is placed inside the sliding shell 23. The activated carbon 24 has a porous structure and is used to adsorb exhaust gas that is difficult to clean and absorb.

[0026] As Figure 2 , Figure 8 and Figure 9 shown in Figure 9 , a support frame 25 is fixedly connected to the upper end of the rotating shaft 21. A first wave ring 26 is fixedly connected to the upper part of the support frame 25. The first wave ring 26 is rotatably connected to the purification cylinder 1. A second wave ring 27 is fixedly connected to the bottom of the sliding shell 23. The second wave ring 27 is in movable contact with the purification cylinder 1. The first wave ring 26 and the second wave ring 27 cooperate to make the second wave ring 27 reciprocate above the first wave ring 26.

[0027] When the absorption liquid is sprayed out from the atomizing nozzle 18, the absorption liquid water mist falls on the activated carbon 24. The porous structure of the activated carbon 24 enables the absorption liquid to be fully filled in the pores of the activated carbon 24, increasing the absorption of the absorption liquid for the exhaust gas. Moreover, the activated carbon 24 itself has the ability to absorb the exhaust gas, further improving the absorption efficiency of the exhaust gas.

[0028] While the exhaust gas enters the circular cylinder 6, the motor 20 is started. The rotation of the motor 20 drives the blades 22 to rotate through the rotating shaft 21, and the blades 22 stir the absorption liquid to make the concentration of the absorption liquid uniform. When the rotation speed of the blades 22 is relatively fast, the blades 22 rotate due to the resistance from the absorption liquid, making the inclination angle of the blades 22 smaller, and the posture of the blades 22 becomes more horizontal, avoiding the absorption liquid from being stirred too quickly by the blades 22 and releasing the exhaust gas. Moreover, when the rotating shaft 21 rotates, it drives the first wave ring 26 to rotate through the support frame 25. The first wave ring 26 reciprocally presses the second wave ring 27 through the wave surface. The second wave ring 27 reciprocates up and down inside the purification cylinder 1. The second wave ring 27 drives the activated carbon 24 to reciprocate synchronously through the sliding shell 23, shaking off the excess absorption liquid in the pores of the activated carbon 24, making the absorption liquid fall back into the absorption liquid on the top of the second partition plate 4, avoiding the porous structure of the activated carbon 24 from being blocked by the absorption liquid, and enabling the exhaust gas to flow upward through the porous structure of the activated carbon 24, improving the absorption efficiency of the exhaust gas.

[0029] AsFigure 2 , Figure 10 and Figure 12 As shown in Figure 12 , a conical hollow block 28 is fixedly connected inside the purification cylinder 1. A disc 29 is fixedly connected to the top of the conical hollow block 28. A plurality of ventilation holes are formed in the disc 29. The disc 29 is fixedly connected to the purification cylinder 1. A lead screw 30 is fixedly connected to the center position of the bottom of the disc 29. A plug 31 is frictionally sleeved on the lead screw 30. A plurality of circumferentially distributed ventilation grooves are formed in the outer wall of the plug 31. A piston ring 32 is sleeved on the outer wall of the plug 31. The piston ring 32 has a small weight and moves quickly when being squeezed. The piston ring 32 is in sliding sealing contact with the top of the ventilation groove of the plug 31. The piston ring 32 is slidably connected to the conical hollow block 28, and a second spring is connected between the piston ring 32 and the disc 29.

[0030] As Figure 2 , Figure 10 and Figure 11 As shown in Figure 11 , a blind hole is formed at the bottom of the conical hollow block 28. A piezoelectric ceramic 33 is slidably connected in the blind hole. The piezoelectric ceramic 33 will release electric charges when being pressured. A third spring is connected between the piezoelectric ceramic 33 and the bottom of the blind hole. The third spring is used to absorb the impact force when the piezoelectric ceramic 33 is impacted. The top of the piezoelectric ceramic 33 is in contact with the piston ring 32. A compression cone 34 is fixedly connected to the top of the disc 29. A mirror-image distributed conductive tip frame 35 is fixedly connected to the upper end of the compression cone 34. The piezoelectric ceramic 33 is electrically connected to the conductive tip frame 35.

[0031] As Figure 2 and Figure 10 As shown in Figure 10 , a heat conduction ring 36 is fixedly connected to the top of the compression cone 34. The bottom of the heat conduction ring 36 is located inside the compression cone 34, which is convenient for the heat conduction ring 36 to heat the waste gas inside the compression cone 34.

[0032] After the waste gas is treated by the absorption liquid at the shunt pipe 801, it will enter the top cavity of the purification cylinder 1 and accumulate continuously, and diffuse upward through the concentration gradient. During the upward diffusion of the waste gas, it passes through the activated carbon 24, and thus is absorbed and treated by the activated carbon 24 and the atomized absorption liquid, and continues to flow upward, filling the top cavity of the purification cylinder 1 with waste gas. The air pressure in the top cavity of the purification cylinder 1 continuously increases until the air pressure of the waste gas overcomes the elastic force of the second spring, the gravity of the plug 31 and the gravity of the piston ring 32. The waste gas treated by the absorption liquid pushes the piston ring 32 to move upward and compress the second spring. During the upward movement of the piston ring 32, it will push the plug 31 to spiral upward along the lead screw 30. When the second spring is completely compressed, the piston ring 32 cannot continue to move upward. At this time, there is still space for the top of the plug 31 to move upward, so that the waste gas pushes the plug 31 to spiral upward along the lead screw 30 until the top of the ventilation groove of the plug 31 disengages from the piston ring 32. At this time, the waste gas at the bottom of the piston ring 32 can be discharged upward through the ventilation groove of the plug 31, and the waste gas is released. The upward pressure on the piston ring 32 decreases. Since the plug 31 is frictionally sleeved on the lead screw 30 in a spiral manner, the plug 31 slowly moves downward along the lead screw 30 under the action of friction. Since the mass of the piston ring 32 is small, the release of the second spring will push the piston ring 32 to generate a large acceleration, causing the piston ring 32 to move downward quickly. The downward movement of the piston ring 32 will impact the piezoelectric ceramic 33 and compress the third spring. The lattice structure inside the piezoelectric ceramic 33 will be deformed by the impact, and thus an instantaneous high voltage will be released under the piezoelectric effect. The instantaneous high voltage is transmitted to the conductive tip holder 35 through the wire. The tips of the two conductive tip holders 35 break down the air and emit electric sparks under the instantaneous high voltage, thus igniting the unabsorbed combustible waste gas in the waste gas, thereby avoiding the pollution of the atmosphere by the combustible waste gas in the waste gas. The temperature generated during the combustion of the waste gas will be absorbed by the heat conduction ring 36, so that the heat conduction ring 36 transfers heat downward. The bottom of the heat conduction ring 36 heats the waste gas in the compression cone 34, avoiding the problem that the waste gas temperature is too low to cause difficult combustion, and thus improving the combustion efficiency of the waste gas.

[0033] An industrial smoke purification device and purification method include the following steps: S1: Connect the external smoke collection device to the intake pipe 2, so that the smoke enters the circular cylinder 6 through the intake pipe 2. The smoke enters the vortex tube 9 to generate hot smoke and cold smoke. The hot smoke and cold smoke pass through the one-way valve 7 and contact the cleaning liquid. The smoke is cleaned of particulate matter to become waste gas. The waste gas enters the shunt pipe 801 and pushes the extrusion plug 803 upward. The waste gas moves upward along the gap between the shunt pipe 801 and the extrusion plug 803, and collides with the absorption liquid in the diversion pipe 804 to generate fine bubbles. The fine bubbles slowly rise under the guidance of the spiral diversion groove of the shunt pipe 801, and the waste gas is initially absorbed by the absorption liquid; S2: When the smoke enters the circular cylinder 6, it blows the impeller 11 to rotate, causing the shaft rod 12 to drive the piston rod 14 to reciprocate in the piston cylinder 15 through the crank 13, so that the absorption liquid in the purification cylinder 1 enters the piston cylinder 15 along the one-way liquid inlet pipe 16 and sprays out from the atomizing nozzle 18 along the one-way liquid outlet pipe 17. The absorption liquid is atomized to further absorb the waste gas. S3: The absorption liquid sprayed by the atomizing nozzle 18 falls on the activated carbon 24. The porous structure of the activated carbon 24 is used to increase the contact area between the absorption liquid and the waste gas, and the activated carbon 24 further absorbs the waste gas. S4: Start the motor 20. The rotation of the motor 20 drives the blades 22 to stir the absorption liquid through the rotating shaft 21, so that the concentration of the absorption liquid is kept uniform and the absorption efficiency of the absorption liquid is improved. The rotation of the rotating shaft 21 passes through the support frame 25, so that the first corrugated ring 26 drives the activated carbon 24 on the sliding shell 23 to reciprocate through the second corrugated ring 27, and the excess absorption liquid is shaken off and returned to the second partition plate 4 to prevent the activated carbon 24 from being blocked. S5: After the waste gas is treated by the absorption liquid at the shunt pipe 801, during the upward diffusion process of the waste gas, it passes through the activated carbon 24, is absorbed and treated by the activated carbon 24 and the atomized absorption liquid and then continues to flow upward. The waste gas accumulates continuously, thus pushing the piston ring 32 to move upward to compress the second spring. The upward movement of the piston ring 32 pushes the plug 31 to spiral upward along the lead screw 30. When the second spring is completely compressed, the plug 31 continues to rise so that the waste gas is discharged upward through the ventilation groove of the plug 31. The second spring releases and pushes the piston ring 32 to impact the piezoelectric ceramic 33. The piezoelectric ceramic 33 releases an instantaneous high voltage, and the instantaneous high voltage releases an electric spark at the tip of the conductive tip frame 35 to ignite the combustible waste gas in the waste gas. The heat generated during the combustion of the waste gas is absorbed by the heat conduction ring 36 and used to heat the waste gas in the compression cone 34, completing the treatment of the waste gas.
