An industrial fume purification device and purification method

Abstract

This invention relates to the field of fume purification technology, and more particularly to an industrial fume purification device and method. The problem this invention aims to solve is the poor treatment effect of existing fume treatment equipment on harmful substances. The technical solution is as follows: An industrial fume purification device includes a purification cylinder, an air inlet pipe fixedly connected to the right side of the purification cylinder, an exhaust port at the top of the purification cylinder, and a first liquid inlet and a second liquid inlet on the left side. It also includes a first partition plate fixedly connected inside the purification cylinder. This invention, by setting an atomization unit, allows exhaust gas to flow upwards through the gap between the distribution pipe and the squeeze plug, and then contact the absorbent liquid through the permeable plate. Because the gap between the distribution pipe and the squeeze plug is small, the exhaust gas flows at high speed as it passes through this gap, attracting the absorbent liquid through the guide pipe into the distribution pipe. The collision between the exhaust gas and the absorbent liquid generates fine bubbles, improving the efficiency of the absorbent liquid in absorbing the exhaust gas.

Description

Technical Field

[0001] This invention relates to the field of fume purification technology, and in particular to an industrial fume purification device and purification method. Background Technology

[0002] A spray tower is a gas purification device that removes pollutants from gases by spraying liquid. It is widely used in fume treatment. When fume enters the spray tower, it combines with the sprayed liquid droplets, thereby adsorbing the pollutants in the gas.

[0003] In the power industry, thermal power plants generate a large amount of heat by burning fossil fuels, which then drives generators to produce electricity through steam turbines. However, the combustion of fossil fuels produces a large amount of smoke, nitrogen oxides, sulfur oxides, volatile organic compounds, ozone, and other harmful substances, which seriously endanger the ecological environment. Although existing smoke treatment equipment can effectively reduce the emission of harmful substances, there are still cases 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 purification method that can efficiently remove harmful substances from smoke. Summary of the Invention

Several atomizing units are included. Each atomizing unit includes a split tube. Several split tubes are fixedly connected between the second partition and the mesh. The bottom of the split tube passes through the second partition. A spiral guide groove is opened inside the split tube. A breather plate is fixedly connected to the top of the split tube.

[0006] Preferably, a vortex tube is fixedly connected to the top of the inner part of the cylindrical tube. Several inclined air inlets are opened on the outer wall of the vortex tube in a circumferential direction. Cold air inlets and hot air inlets are opened at the upper and lower ends of the vortex tube, respectively. A fourth partition is fixedly connected to the lower outer wall of the vortex tube. The fourth partition is fixedly connected to the cylindrical tube and is located between the one-way valves distributed in the upper and lower parts.

[0007] Preferably, an impeller is rotatably mounted at the top of the cylindrical tube, and the impeller is fixed to the top of the shaft. Two cranks are rotatably connected at the eccentric end of the lower end of the shaft, and a piston rod is rotatably connected to the end of each of the two cranks. A piston cylinder is slidably sleeved through the outer wall of the piston rod. The piston cylinder is fixedly connected to the purification tube and is connected to a one-way liquid inlet pipe and a one-way liquid outlet pipe. Both the one-way liquid inlet pipe and the one-way liquid outlet pipe pass through the purification tube, and multiple atomizing nozzles are installed on the one-way liquid outlet pipe.

[0008] Preferably, a sealing shell is fixedly connected between the second partition and the partition net, and a motor is installed inside the sealing shell. The output shaft of the motor passes through the center of the partition net and is fixedly connected to a rotating shaft. Several circumferentially distributed blades are rotatably connected on the circumferential wall of the rotating shaft, and a spring is rotatably connected between the rotating shaft and the blades.

[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 wave ring is fixedly connected to the upper part of the support frame, the first wave ring is rotatably connected to the purification cylinder, a second wave ring is fixedly connected to the bottom of the sliding shell, the second wave ring is in movable contact with the purification cylinder, and the first wave ring and the second wave ring cooperate.

[0011] Preferably, a conical hollow block is fixed to the top of the purification cylinder, and a disc is fixed to the top of the conical hollow block. The disc has several ventilation holes and is fixed to the purification cylinder. A lead screw is fixed to the center of the bottom of the disc, and a stopcock is fitted on the lead screw with a friction thread. Several circumferentially distributed ventilation grooves are opened on the outer wall of the stopcock. A piston ring is fitted on the outer wall of the stopcock. The piston ring is slidably connected to the conical hollow block, and a second spring connects the piston ring and the disc.

[0012] Preferably, a blind hole is provided at the bottom of the conical hollow block, a piezoelectric ceramic is slidably connected in the blind hole, a third spring is connected between the piezoelectric ceramic and the bottom of the blind hole, the top of the piezoelectric ceramic is in contact with the piston ring, a compression cone is fixedly connected to the top of the disc, a conductive tip is fixedly connected to the upper end of the compression cone, and the piezoelectric ceramic and the conductive tip are electrically connected.

[0013] Preferably, a heat-conducting ring is fixed to the top of the compression cone, and the bottom of the heat-conducting ring is located inside the compression cone.

[0014] A purification method for an industrial fume purification device includes the following steps:

[0015] S1: Connect the external smoke collection device to the air inlet pipe, so that the smoke enters the cylinder through the air inlet pipe. The smoke enters the vortex tube and generates hot smoke and cold smoke. The hot smoke and cold smoke pass through the one-way valve and come into contact with the cleaning liquid. The smoke washes away the particulate matter and becomes exhaust gas. The exhaust gas enters the diversion pipe and pushes the squeeze plug to move upward. The exhaust gas moves upward along the gap between the diversion pipe and the squeeze plug and collides with the absorbent in the guide pipe to generate fine bubbles. The fine bubbles rise slowly under the guidance of the spiral guide groove of the diversion pipe. The exhaust gas is initially absorbed by the absorbent.

[0016] S2: When the smoke enters the cylindrical tube, it blows the impeller to rotate, causing the shaft to drive the piston rod to reciprocate inside the piston cylinder through the crank. This causes the absorbent liquid in the purification cylinder to enter the piston cylinder along the one-way inlet pipe and be sprayed out from the atomizing nozzle along the one-way outlet pipe. The absorbent liquid is atomized and further absorbs the exhaust gas.

[0017] S3: The absorbent liquid sprayed from the atomizing nozzle falls onto the activated carbon. The porous structure of the activated carbon increases the contact area between the absorbent liquid and the waste gas, allowing the activated carbon to further absorb the waste gas.

[0018] S4: Start the motor. The motor rotates and drives the blades to stir the absorbent liquid through the rotating shaft, so that the concentration of the absorbent liquid is kept uniform and the absorption efficiency of the absorbent liquid is improved. The rotating shaft rotates through the support frame, so that the first wave ring drives the activated carbon on the sliding shell to move back and forth through the second wave ring. Excess absorbent liquid is shaken off and returned to the second partition plate to avoid the activated carbon from being blocked.

[0019] S5: After being treated by the absorbent liquid at the diversion pipe, the exhaust gas diffuses upwards and passes through activated carbon. It is then absorbed and treated by the activated carbon and the atomized absorbent liquid before continuing to flow upwards. The exhaust gas accumulates, which pushes the piston ring upwards to compress the second spring. The upward movement of the piston ring pushes the plug to spiral upwards along the screw. When the second spring is fully compressed, the plug continues to rise, allowing the exhaust gas to be discharged upwards through the vent groove of the plug. The second spring releases and pushes the piston ring to strike the piezoelectric ceramic. The piezoelectric ceramic releases a momentary high voltage. The momentary high voltage releases an electric spark at the tip of the conductive tip, igniting the combustible exhaust gas. The heat from the combustion of the exhaust gas is absorbed by the heat-conducting ring and heats the exhaust gas, completing the exhaust gas treatment.

[0020] The beneficial effects of this invention are:

[0021] This invention incorporates an atomizing unit. Exhaust gas overcomes the spring force of the first spring through air pressure, entering the extrusion and distribution pipe. This extrusion pushes the extrusion plug, compressing the first spring. The exhaust gas flows upward through the gap between the distribution pipe and the extrusion plug, and then contacts the absorbent liquid via a permeable plate. Due to the small gap between the distribution pipe and the extrusion plug, based on Bernoulli's principle, the gas flows at high speed as it passes through this gap, reducing the pressure inside the distribution pipe. This attracts the absorbent liquid through the guide pipe into the distribution pipe. The collision between the exhaust gas and the absorbent liquid generates a large number of fine bubbles, improving the efficiency of the absorbent liquid in absorbing the exhaust gas.

Detailed Implementation

[0035] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0036] like Figure 1 , Figure 4As shown, an industrial fume purification device includes a purification cylinder 1. An air inlet pipe 2 is fixedly connected to one side of the purification cylinder 1, and the air inlet pipe 2 is connected to an external fume collection device. An exhaust port 101 is opened at the top of the purification cylinder 1, and 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 connected to the bottom of the purification cylinder 1, and a second partition 4 and a mesh 5 are fixedly connected to the bottom of the purification cylinder 1. The internal space of the purification cylinder 1 below the first partition 3 is the bottom cavity, and the space between the first partition 3 and the second partition 4 inside the purification cylinder 1 is the middle cavity. The purification cylinder 1 has a central cavity containing cleaning fluid. The space above the second partition 4 within the purification cylinder 1 is the top cavity, which contains absorbent fluid, occupying one-quarter of the volume of the top cavity. A circular cylinder 6 is fixedly connected to the top of the first partition 3, and is connected to the air inlet pipe 2. Several one-way valves 7 are installed on the outer circumferential wall of the circular cylinder 6, with the upper one-way valve 7 slightly lower than the cleaning fluid level. Several... Each atomizing unit 8 includes a diversion tube 801. Several diversion tubes 801 are fixedly connected between the second partition 4 and the mesh 5. The bottom of each diversion tube 801 penetrates the second partition 4. A spiral guide groove is formed inside each diversion tube 801 to increase the contact area between the smoke and the absorbent liquid and to slow down the upward flow of the smoke. A vent plate 802 is fixedly connected to the top of each diversion tube 801. A gap is left at the connection between the top of the diversion tube 801 and the vent plate 802 to facilitate the upward flow of the smoke. A squeeze plug 803 is slidably connected inside each diversion tube 801. The spherical surface at the lower end of the squeeze plug 803 is in sealed contact with the conical surface inside the diverter tube 801, and there is a gap between the cylindrical surface of the squeeze plug 803 and the inner wall of the diverter tube 801. The squeeze plug 803 is made of nickel-iron alloy, which has good corrosion resistance and high temperature resistance, preventing itself from being corroded by the absorbent liquid or smoke. A first spring is connected between the vent plate 802 and the squeeze plug 803. Several guide tubes 804 are evenly connected on the outer circumference of the diverter tube 801. The guide tubes 804 are inclined downward so that the gas will not enter the guide tubes 804 when passing through the diverter tube 801.

[0037] like Figure 5 and Figure 6As shown, a vortex tube 9 is fixedly connected to the top of the inner part of the cylindrical tube 6. The vortex tube 9 converts the gas entering it into cold gas and hot gas. Several inclined air inlets 901 are circumferentially opened on the outer wall of the vortex tube 9. The axis of the air inlets 901 is offset from the axis of the vortex tube 9, so that when the gas enters the vortex tube 9 through the air inlets 901, a vortex is formed in the vortex tube 9. A hot air inlet 902 is opened at the bottom of the vortex tube 9, and a cold air inlet 903 is opened at the top. A fourth partition 10 is fixedly connected to the lower outer wall of the vortex tube 9. The fourth partition 10 is fixedly connected to the cylindrical tube 6. The fourth partition 10 is located between the one-way valves 7 distributed vertically, so as to isolate the hot gas ejected from the hot air inlet 902 from the cold gas ejected from the cold air inlet 903.

[0038] Before using this device, connect the external smoke collection device to the air inlet pipe 2. Smoke enters the cylindrical cylinder 6 through the air inlet pipe 2, and then enters the vortex tube 9 through the air inlet 901. Guided by the air inlet 901, the smoke spirals downwards within the vortex tube 9, forming a vortex. When the smoke enters the vortex tube 9 at a constant speed, the angular velocity at the center of the vortex is higher than that at the edge. Due to the difference in angular velocities, friction occurs between the smoke at the center and the smoke at the edge of the vortex. This friction slows down the angular velocity of the smoke at the center of the vortex, thus reducing its energy and turning it into cold smoke. Conversely, the angular velocity of the smoke at the edge of the vortex increases, increasing its energy. Furthermore, friction occurs between the edge of the vortex and the inner wall of the vortex tube 9, turning it into hot smoke. Hot smoke is ejected from the hot air hole 902 and enters the cylindrical cylinder 6. The angular momentum of the smoke flow inside the vortex tube 9 is conserved. While the hot smoke spirals downwards, the cold smoke spirals upwards in the opposite direction and is ejected from the cold air hole 903 of the vortex tube 9 into the cylindrical cylinder 6. At this time, the fourth baffle 10 separates the hot and cold smoke inside the cylindrical cylinder 6, preventing them from mixing. The hot smoke from the hot air hole 902 is then ejected through the one-way valve 7 at the bottom of the cylindrical cylinder 6 and comes into contact with the cleaning fluid. The heat of the hot smoke is absorbed by the cleaning fluid, raising its temperature. This reduces the absorption rate of soluble waste gas in the smoke by the cleaning fluid, increases its service life, and reduces interference from soluble waste gas. The separation of the cold and hot smoke by the fourth baffle 10 further enhances the cooling effect. The cold smoke emitted from vent 903 is ejected through the one-way valve 7 at the top of the cylindrical cylinder 6 and comes into contact with the cleaning fluid. When the smoke comes into contact with the cleaning fluid, the particulate matter in the smoke is adhered to the cleaning fluid, causing the smoke components to transform into exhaust gas. After the cold smoke and hot smoke are cleaned and turned into exhaust gas by the cleaning fluid, they mix on the surface of the cleaning fluid. This exhaust gas accumulates in the middle cavity of the purification cylinder 1, causing the internal air pressure in the middle cavity of the purification cylinder 1 to gradually increase. The exhaust gas enters the bottom of the diversion pipe 801 and pushes the squeeze plug 803 through the air pressure. The squeeze plug 803 moves upward and compresses the first spring. It is worth noting that since the lower end of the diversion pipe 801 is located at the bottom of the second partition 4, the spherical surface of the lower end of the squeeze plug 803 is in sealed contact with the conical surface inside the diversion pipe 801, and the cylindrical surface of the squeeze plug 803 is in contact with the diversion pipe. A gap exists between the inner walls of 801, allowing the absorbent liquid to enter the diversion pipe 801 through the gap between the top of the diversion pipe 801 and the vent plate 802. This fills the gap between the cylindrical surface of the squeeze plug 803 and the inner wall of the diversion pipe 801. The squeeze plug 803 moves upward, creating a gap between its lower spherical surface and the diversion pipe 801. Exhaust gas flows upward through the gap between the diversion pipe 801 and the squeeze plug 803, passing through the absorbent liquid within the diversion pipe 801. Air pressure prevents the absorbent liquid from flowing downward through the gap between the diversion pipe 801 and the squeeze plug 803. The exhaust gas then contacts the absorbent liquid through the vent plate 802. Due to the small gap between the diversion pipe 801 and the squeeze plug 803, based on Bernoulli's principle, the gas flows at a high speed as it passes through this gap.The pressure at the connection between the diversion pipe 801 and the guide pipe 804 decreases, causing the absorbent liquid to flow from the high-pressure area to the low-pressure area. It then enters the diversion pipe 801 through the guide pipe 804. The upward-flowing waste gas in the diversion pipe 801 collides with the absorbent liquid flowing at the guide pipe 804, generating a large number of fine bubbles. These bubbles are guided upwards by the spiral guide grooves of the diversion pipe 801, slowing their ascent and ensuring that the waste gas within the bubbles is fully absorbed by the absorbent liquid, thus improving the efficiency of the absorbent liquid in absorbing waste gas.

[0039] like Figure 5 , Figure 7 As shown, an impeller 11 is rotatably mounted on the top of the cylindrical cylinder 6. The impeller 11 is fixed to the top of the shaft 12. Two cranks 13 are rotatably connected to the eccentric part of the lower end of the shaft 12. A piston rod 14 is rotatably connected to the end of each of the two cranks 13. A piston cylinder 15 is slidably fitted through the outer wall of the piston rod 14. The piston cylinder 15 is fixed to the purification cylinder 1. The two cranks 13 share a shaft 12, so that the piston rods 14 in the two piston cylinders 15 always move in opposite directions. The piston cylinder 15 is connected to a one-way inlet pipe 16 and a one-way outlet pipe 17. Both 16 and 17 have unidirectional flow function. Both 16 and 17 penetrate the purification cylinder 1. The end of the 16 away from the piston cylinder 15 is connected to the lower part of the top cavity of the purification cylinder 1. The end of the 17 away from the piston cylinder 15 is connected to the upper part of the top cavity of the purification cylinder 1. Multiple upward-facing atomizing nozzles 18 are installed at the end of the top cavity of the 17. The water mist sprayed by the atomizing nozzles 18 is disc-shaped, which increases the contact area between the water mist and the exhaust gas in the purification cylinder 1.

[0040] 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 12 to rotate synchronously. The shaft 12 drives the piston rod 14 to reciprocate inside the piston cylinder 15 via the crank 13. When the internal volume of the piston cylinder 15 increases, the internal pressure of the piston cylinder 15 decreases. Since both the one-way inlet pipe 16 and the one-way outlet pipe 17 have a one-way guiding function, the piston cylinder 15 draws absorbent liquid above the mesh 5 through the one-way inlet pipe 16. When the internal volume of the piston cylinder 15 decreases, the internal pressure of the piston cylinder 15 increases, and the piston cylinder 15 draws absorbent liquid above the mesh 5 through the one-way outlet pipe 17. Liquid pipe 17 delivers absorbent to atomizing nozzle 18. The absorbent is atomized by spraying from atomizing nozzle 18, increasing the absorption area between the absorbent and the exhaust gas, and improving the efficiency of the absorbent in absorbing the exhaust gas. The faster the exhaust gas blows the impeller 11 to rotate, the faster the shaft 12 drives the piston rod 14 to reciprocate through crank 13. The piston cylinder 15 drives the absorbent to spray out a larger flow rate from atomizing nozzle 18, so that the speed at which the absorbent is sprayed out from atomizing nozzle 18 is balanced with the speed at which the exhaust gas enters the circular cylinder 6, avoiding excessive water mist sprayed from atomizing nozzle 18 and causing waste.

[0041] like Figure 3 , Figure 8 and Figure 9 As shown, a sealing shell 19 is fixedly connected between the second partition 4 and the partition 5. A motor 20 is installed inside the sealing shell 19. The output shaft of the motor 20 passes through the center of the partition 5 and is fixedly connected to a rotating shaft 21. Several circumferentially distributed blades 22 are rotatably connected to the circumferential wall of the rotating shaft 21. A spring is rotatably connected between the rotating shaft 21 and the blades 22. The blades 22 can adjust their tilt angle based on their own rotation speed to prevent the waste gas in the absorbent liquid from being agitated and released in large quantities by the blades 22.

[0042] like Figure 2 and Figure 8 As shown, a sliding shell 23 is slidably connected inside the purification cylinder 1, and activated carbon 24 is placed inside the sliding shell 23. The activated carbon 24 has a porous structure and is used to adsorb waste gas that is difficult to clean and absorb.

[0043] like Figure 2 , Figure 8 and Figure 9 As shown, a support frame 25 is fixedly connected to the upper end of the rotating shaft 21, and 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.

[0044] When the absorbent is sprayed from the atomizing nozzle 18, the water mist of the absorbent falls onto the activated carbon 24. The porous structure of the activated carbon 24 allows the absorbent to fully fill the pores of the activated carbon 24, increasing the absorption of the waste gas by the absorbent. In addition, the activated carbon 24 itself has the ability to absorb waste gas, further improving the absorption efficiency of the waste gas.

[0045] As 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 via the rotating shaft 21. The blades 22 agitate the absorbent liquid, making the concentration of the absorbent liquid uniform. When the blades 22 rotate at a relatively high speed, the blades 22 rotate due to the resistance from the absorbent liquid, making the tilt angle of the blades 22 smaller and the posture of the blades 22 more horizontal. This prevents the absorbent liquid from being agitated too quickly by the blades 22 and releasing the exhaust gas. When the rotating shaft 21 rotates, it drives the first wave ring 26 to rotate via the support frame 25. The first wave ring 26 reciprocates by pressing the second wave ring 27 through the wave surface. The second wave ring 27 moves up and down in the purification cylinder 1. The second wave ring 27 drives the activated carbon 24 to move back and forth synchronously via the sliding shell 23, shaking off the excess absorbent liquid in the pores of the activated carbon 24 and letting the absorbent liquid fall back into the absorbent liquid at the top of the second partition 4. This prevents the porous structure of the activated carbon 24 from being blocked by the absorbent liquid, allowing the exhaust gas to flow upward through the porous structure of the activated carbon 24 and improving the absorption efficiency of the exhaust gas.

[0046] like Figure 2 , Figure 10 and Figure 12 As shown, 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. Several ventilation holes are opened on the disc 29. The disc 29 is fixedly connected to the purification cylinder 1. A lead screw 30 is fixedly connected to the center of the bottom of the disc 29. A plug 31 is fitted on the lead screw 30 with a friction thread. Several circumferentially distributed ventilation grooves are opened on the outer wall of the plug 31. A piston ring 32 is fitted on the outer wall of the plug 31. The piston ring 32 is relatively light and moves quickly when 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.

[0047] like Figure 2 , Figure 10 and Figure 11 As shown, a blind hole is provided at the bottom of the conical hollow block 28, and a piezoelectric ceramic 33 is slidably connected inside the blind hole. The piezoelectric ceramic 33 will release an electric charge when it is subjected to pressure. 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 hit. The top of the piezoelectric ceramic 33 is in contact with the piston ring 32. A compression cone 34 is fixed to the top of the disc 29. A mirror-distributed conductive tip 35 is fixed to the upper end of the compression cone 34. The piezoelectric ceramic 33 and the conductive tip 35 are electrically connected.

[0048] like Figure 2 and Figure 10 As shown, a heat-conducting ring 36 is fixed to the top of the compression cone 34, and the bottom of the heat-conducting ring 36 is located inside the compression cone 34, so that the heat-conducting ring 36 can heat the exhaust gas inside the compression cone 34.

[0049] After being treated by the absorbent liquid at the diversion pipe 801, the waste gas enters the top cavity of the purification cylinder 1 and accumulates continuously. It diffuses upwards through the concentration gradient, passing through activated carbon 24 and being absorbed by both the activated carbon 24 and the atomized absorbent liquid. The gas continues to flow upwards, filling the top cavity of the purification cylinder 1 with waste gas. The gas pressure in the top cavity of the purification cylinder 1 continuously increases until the waste gas pressure overcomes the elastic force of the second spring, the weight of the stopcock 31, and the weight of the piston ring 32. The waste gas, treated by the absorbent liquid, then pushes the activated carbon 24 to absorb the waste gas. As piston ring 32 moves upward, it compresses the second spring. During this upward movement, piston ring 32 pushes plug 31 spirally upward along screw 30. When the second spring is fully compressed, piston ring 32 can no longer move upward. At this point, the top of plug 31 still has room to move upward, allowing exhaust gas to push plug 31 spirally upward along screw 30 until the top of plug 31's vent groove disengages from piston ring 32. At this point, exhaust gas at the bottom of piston ring 32 can be discharged upward through the vent groove of plug 31, releasing the exhaust gas and allowing the piston ring to... As the upward pressure on piston ring 32 decreases, and since the piston plug 31 is friction-type spirally sleeved on the lead screw 30, the piston plug 31 slowly moves downward along the lead screw 30 under the action of friction. Because piston ring 32 has a relatively small mass, the release of the second spring will push piston ring 32 to generate a large acceleration, causing piston ring 32 to move downward rapidly. The downward movement of piston ring 32 will impact piezoelectric ceramic 33, causing piezoelectric ceramic 33 to compress the third spring. The internal lattice structure of piezoelectric ceramic 33 will deform under the impact, thus releasing under the piezoelectric effect. A momentary high voltage is transmitted through a conductor to the conductive tips 35. The tips of the two conductive tips 35 break down the air under the momentary high voltage and release an electric spark, thereby igniting the unabsorbed combustible waste gas in the exhaust gas. This prevents the combustible waste gas from polluting the atmosphere. The temperature generated during the combustion of the exhaust gas is absorbed by the heat-conducting ring 36, which then transfers heat downwards. The bottom of the heat-conducting ring 36 heats the exhaust gas inside the compression cone 34, preventing the exhaust gas from being too cold and thus improving the combustion efficiency of the exhaust gas.

[0050] An industrial fume purification device and method, comprising the following steps:

[0051] S1: Connect the external smoke collection device to the air inlet pipe 2, so that the smoke enters the cylindrical tube 6 through the air inlet 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 come into contact with the cleaning liquid. The smoke washes away the particulate matter and becomes exhaust gas. The exhaust gas enters the diversion pipe 801 and pushes the squeeze plug 803 to move upward. The exhaust gas moves upward along the gap between the diversion pipe 801 and the squeeze plug 803, and collides with the absorbent in the guide pipe 804 to generate fine bubbles. The fine bubbles rise slowly under the guidance of the spiral guide groove of the diversion pipe 801, and the exhaust gas is initially absorbed by the absorbent.

[0052] S2: When the smoke enters the cylindrical cylinder 6, it blows the impeller 11 to rotate, causing the shaft 12 to drive the piston rod 14 to reciprocate in the piston cylinder 15 through the crank 13. This causes the absorbent liquid in the purification cylinder 1 to enter the piston cylinder 15 along the one-way inlet pipe 16 and be sprayed out from the atomizing nozzle 18 along the one-way outlet pipe 17. The absorbent liquid is atomized and further absorbs the exhaust gas.

[0053] S3: The absorbent liquid sprayed from the atomizing nozzle 18 falls onto the activated carbon 24. The porous structure of the activated carbon 24 increases the contact area between the absorbent liquid and the waste gas, and the activated carbon 24 further absorbs the waste gas.

[0054] S4: Start motor 20. The rotation of motor 20 drives blade 22 to stir the absorbent liquid through rotating shaft 21, so that the concentration of absorbent liquid is kept uniform and the absorption efficiency of absorbent liquid is improved. Rotating shaft 21 rotates through support frame 25, so that the first wave ring 26 drives the activated carbon 24 on sliding shell 23 to move back and forth through second wave ring 27. Excess absorbent liquid is shaken off and returned to the second partition 4 to avoid the activated carbon 24 from being blocked.

[0055] S5: After being treated by the absorbent liquid at the diversion pipe 801, the waste gas diffuses upwards and passes through the activated carbon 24. After being absorbed and treated by the activated carbon 24 and the atomized absorbent liquid, the waste gas continues to flow upwards. The waste gas accumulates continuously, thereby pushing the piston ring 32 to move upwards and compress the second spring. The upward movement of the piston ring 32 pushes the plug 31 to spiral upwards along the screw 30. When the second spring is fully compressed, the plug 31 continues to rise, allowing the waste gas to be discharged upwards through the vent groove of the plug 31. The second spring is released and pushes the piston ring 32 to strike the piezoelectric ceramic 33. The piezoelectric ceramic 33 releases instantaneous high voltage. The instantaneous high voltage releases an electric spark at the tip of the conductive tip 35, igniting the combustible waste gas in the waste gas. The heat from the combustion of the waste gas is absorbed by the heat-conducting ring 36 and heats the waste gas in the compression cone 34, completing the waste gas treatment.

[0056] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.

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 come into contact with the cleaning liquid. The smoke washes away the particulate matter and becomes exhaust gas. The exhaust gas enters the diversion pipe (801) and pushes the squeeze plug (803) to move upward. The exhaust gas moves upward along the gap between the diversion pipe (801) and the squeeze plug (803) and collides with the absorbent in the guide pipe (804) to generate fine bubbles. The fine bubbles rise slowly under the guidance of the spiral guide groove of the diversion pipe (801). The exhaust gas is initially absorbed by the absorbent. S2: When the smoke enters the cylindrical tube (6), it blows the impeller (11) to rotate, causing the shaft (12) to drive the piston rod (14) to reciprocate in the piston cylinder (15) through the crank (13), so that the absorbent liquid in the purification tube (1) enters the piston cylinder (15) along the one-way liquid inlet pipe (16) and is sprayed out from the atomizing nozzle (18) along the one-way liquid outlet pipe (17).

The rotating shaft (21) rotates through the support frame (25), so that the first wave ring (26) drives the activated carbon (24) on the sliding shell (23) to move back and forth through the second wave ring (27). Excess absorbent liquid is shaken off and returned to the second partition (4) to avoid the activated carbon (24) from being blocked. S5: After the exhaust gas is treated by the absorbent liquid at the diversion pipe (801), it diffuses upward and passes through the activated carbon (24). After being absorbed and treated by the activated carbon (24) and the atomized absorbent liquid, it continues to flow upward. The exhaust gas accumulates continuously, thereby pushing the piston ring (32) to move upward and compress the second spring. The piston ring (32) moves upward and pushes the rotary valve (31) to spiral up along the screw (30). When the second spring is fully compressed, the rotary valve (31) continues to rise, allowing the exhaust gas to be discharged upward through the ventilation groove of the rotary valve (31).
