Description

Technical Field

[0001] The present invention relates to the technical field of flue gas purification and treatment, and particularly relates to a flue gas purification and treatment device. Background Art

[0002] In the process of treating hazardous waste, the hazardous waste is put into an incinerator for incineration. During the incineration process, a large amount of waste gas is generated, and the waste gas contains acidic substances and dust. If the waste gas is not treated, in the long-term emission, it will cause serious pollution to the atmospheric environment. Therefore, it is necessary to treat the emitted waste gas and only discharge it into the atmosphere after safe treatment.

[0003] The existing flue gas pretreatment device (Publication No.: CN213375863U) has at least the following drawbacks: The above patent passes flue gas into the absorption tank through a shunt pipe, and the absorption liquid in the absorption tank treats the harmful substances in the flue gas; since the flue gas is likely to form bubbles in the absorption liquid after being introduced into the absorption liquid, and only the outer surface of each bubble contacts the absorption liquid, the flue gas inside the bubble cannot contact the absorption liquid, resulting in the flue gas in the bubble being discharged without participating in the flue gas purification treatment, leading to incomplete flue gas purification treatment. Summary of the Invention

An extrusion ring corresponding to the guide post is fixedly installed on the inner wall of the treatment tank. Both ends of the extrusion ring are provided with inclined surfaces. The end of the guide post intermittently abuts against the inner ring of the extrusion ring.

[0009] As a further solution of the present invention, a vibration mechanism is installed at the bottom of the reaction cylinder. The vibration mechanism includes an annular groove formed on the bottom wall of the reaction cylinder. A rotating ring is rotatably installed on the inner wall of the annular groove. A plurality of hemispherical protrusions are evenly fixedly installed on the upper surface of the rotating ring in the circumferential direction. An annular vibration piece is fixedly installed on the inner wall of the annular groove. A plurality of grooves corresponding to the hemispherical protrusions are formed on the lower surface of the annular vibration piece.

[0012] As a further solution of the present invention, a return spring is sleeved on the outer surface of the pressing column, and the return spring is arranged between the upper surfaces of the pressing plate and the support disc.

[0013] As a further solution of the present invention, a driving mechanism for driving the support disc to rotate is installed on the outer surface of the treatment tank.

[0014] The beneficial effects of the present invention are as follows: 1. By driving the transmission gear to rotate through the stepping motor, the transmission gear drives the support disc to rotate through the toothed ring meshing with it, so that the support disc drives a plurality of reaction cylinders and the corresponding pressing columns to rotate synchronously. When the pressing plate disengages from the pressure sensor and abuts against the inclined surface of the notch of the lower pressing ring, the electromagnetic valve installed on the corresponding feed pipe closes, so that the corresponding reaction cylinder stops feeding. The lower pressing ring will push the pressing disc downward through the pressing plate and the pressing column, so that the extrusion disc pressurizes the flue gas and the absorption liquid in the reaction cylinder, improves the density of the reactant molecules, increases the collision frequency between the molecules, improves the reaction rate of the flue gas and the absorption liquid, and further speeds up the efficiency of the flue gas purification treatment. And it can eliminate the bubbles generated by the flue gas in the absorption liquid, avoiding the flue gas in the bubbles being discharged without participating in the flue gas purification treatment, resulting in incomplete flue gas purification treatment; 2. While the pressing plate abuts against the inclined surface of the notch of the lower pressing ring and moves downward, it will drive the guide rod and the movable plug to move downward, so that the movable plug squeezes the gas in the piston cylinder into the annular groove opened at the bottom wall of the reaction cylinder through the air inlet pipe. Since the air outlet of the air inlet pipe is tangent to the outer circumference of the rotating ring, the flow of the gas can blow the blades to move, so that the rotating ring can rotate quickly. The hemispherical protrusion installed on the top of the rotating ring and the groove opened on the lower surface of the annular vibrating piece can make the annular vibrating piece vibrate, so that the absorption liquid in the reaction cylinder can vibrate accordingly, further splitting or eliminating the flue gas bubbles in the absorption liquid, improving the contact efficiency between the bubbles and the reactants in the absorption liquid, and further improving the effect of the flue gas purification treatment.

Next, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0019] Refer to the attached Figure 1 - attached Figure 9, A flue gas purification and treatment device, including a treatment tank 1. A support disk 2 is rotatably installed on the inner wall of the treatment tank 1. A plurality of reaction cylinders 3 are evenly and fixedly installed on the circumferential direction of the lower surface of the support disk 2. The outer surface of each reaction cylinder 3 near its top is fixedly installed with a feed pipe 4 communicating with its interior. The tops of the multiple feed pipes 4 extend upward out of the top of the treatment tank 1. And a sealing ring 6 is fixedly installed between the outer surfaces of the multiple feed pipes 4 at the connection with the treatment tank 1. The sealing ring 6 is rotatably installed with the top of the treatment tank 1. A discharge hole is penetrated and opened at the bottom end of the reaction cylinder 3. The tops of the multiple feed pipes 4 are installed with a rotary joint 5 communicating with their interiors. An air outlet hole 9 is penetrated and opened on the upper surface of the support disk 2. An air outlet pipe 8 communicating with its interior is fixedly installed at the top end of the treatment tank 1. A discharge pipe 7 communicating with its interior is fixedly installed at the bottom end of the treatment tank 1. A pressurizing mechanism is installed inside each reaction cylinder 3. A driving mechanism for driving the support disk 2 to rotate is installed on the outer surface of the treatment tank 1. The driving mechanism includes a toothed ring 32 fixedly installed on the upper surface of the support disk 2. A driving box 31 is penetrated and fixedly installed on the outer surface of the treatment tank 1. A stepping motor 34 is fixedly installed at the top end of the driving box 31. The output end of the stepping motor 34 penetrates the top wall of the driving box 31 and is fixedly installed with a transmission gear 33. The transmission gear 33 meshes with the toothed ring 32.

[0020] In this embodiment, the pressurizing mechanism includes a pressurizing disk 12 slidably installed inside the reaction cylinder 3. A pressure column 11 is fixedly installed at the top end of the pressurizing disk 12. A pressing plate 13 is fixedly installed at the top end of the pressure column 11. A lower pressing ring 15 is fixedly installed on the top wall of the treatment tank 1. A notch is opened on the outer side of the lower pressing ring 15, and the notch of the lower pressing ring 15 is provided with an inclined surface. A pressure sensor is fixedly installed on the top wall of the treatment tank 1 near the notch of the lower pressing ring 15. An electromagnetic sensor is also installed at the pressure sensor. After the pressure sensor detects the pressure, the electromagnetic sensor is conducted to control the solenoid valve 10. The top end of the pressing plate 13 is attached to the lower surface of the lower pressing ring 15. A solenoid valve 10 that conducts unidirectionally into the reaction cylinder 3 is installed on the feed pipe 4. A sealing component for intermittently blocking the discharge hole is installed at the bottom of the reaction cylinder 3. A return spring 14 is sleeved on the outer surface of the pressure column 11. The return spring 14 is arranged between the pressing plate 13 and the upper surface of the support disk 2.

[0021] During use, the flue gas and the absorbent liquid are connected to the rotary joint 5, so that the flue gas and the absorbent liquid enter the reaction cylinder 3 through the feed pipe 4, and the flue gas reacts with the absorbent liquid to carry out flue gas purification treatment on the flue gas. At the same time, the stepping motor 34 drives the transmission gear 33 to rotate, so that the transmission gear 33 drives the support disk 2 to rotate through the toothed ring 32 meshing with it, and the support disk 2 drives a plurality of reaction cylinders 3 to rotate synchronously with the corresponding pressure columns 11. When the pressing plate 13 disengages from the pressure sensor and abuts against the inclined surface of the notch of the lower pressing ring 15, the solenoid valve 10 installed on the corresponding feed pipe 4 closes, so that the corresponding reaction cylinder 3 stops feeding. The lower pressing ring 15 will push the pressure plate 12 downward through the pressing plate 13 and the pressure column 11, so that the extrusion plate 12 pressurizes the flue gas and the absorbent liquid in the reaction cylinder 3, increases the density of the reactant molecules, increases the collision frequency between the molecules, improves the reaction rate of the flue gas and the absorbent liquid, and then speeds up the efficiency of the flue gas purification treatment. And it can eliminate the bubbles generated by the flue gas in the absorbent liquid, avoiding the flue gas in the bubbles being discharged without participating in the flue gas purification treatment, resulting in incomplete flue gas purification treatment.

[0022] In this embodiment, the sealing assembly includes a support frame 16 fixedly installed at the bottom end of the reaction cylinder 3. A sealing block 17 is slidably installed on the inner wall of the support frame 16. The upper surface of the sealing block 17 is attached to the bottom end of the reaction cylinder 3. A through hole 18 matching the discharge hole is formed through the lower surface of the sealing block 17. A spring rod 19 is fixedly installed on the outer surface of the support frame 16. The telescopic end of the spring rod 19 is fixedly installed on the outer surface of the sealing block 17. An extrusion assembly is installed between the sealing block 17 and the inner wall of the treatment tank 1. The extrusion assembly includes a guide post 20 fixedly installed at one end of the sealing block 17 close to the treatment tank 1. An extrusion ring 21 corresponding to the guide post 20 is fixedly installed on the inner wall of the treatment tank 1. Both ends of the extrusion ring 21 are provided with inclined surfaces, and the end of the guide post 20 intermittently abuts against the inner ring of the extrusion ring 21.

[0023] When the pressure plate 12 moves downward, the guide post 20 installed at the end of the corresponding sealing block 17 will abut against the inner ring of the extrusion ring 21, so that the sealing block 17 is pushed to block the discharge hole opened at the bottom of the reaction cylinder 3, making the inside of the reaction cylinder 3 a closed space, so that the pressure plate 12 can pressurize the flue gas and the absorbent liquid inside the reaction cylinder 3. As the support disk 2 continues to rotate, after the guide post 20 moves to the end of the extrusion ring 21 and separates from its inner ring, the sealing block 17 will reset under the elastic force of the spring rod 19, aligning the through hole 18 with the discharge hole opened at the bottom of the reaction cylinder 3, so that the reacted flue gas and absorbent liquid in the reaction cylinder 3 can be discharged.

[0024] In this embodiment, a vibration mechanism is installed at the bottom of the reaction cylinder 3. The vibration mechanism includes an annular groove formed in the bottom wall of the reaction cylinder 3. A rotating ring 22 is rotatably installed on the inner wall of the annular groove. A plurality of hemispherical protrusions 24 are uniformly and fixedly installed on the upper surface of the rotating ring 22 in the circumferential direction. An annular vibrating piece 25 is fixedly installed on the inner wall of the annular groove. A plurality of grooves corresponding to the hemispherical protrusions 24 are formed on the lower surface of the annular vibrating piece 25. An air venting assembly for driving the rotation of the rotating ring 22 is installed on the lower surface of the support plate 2. The air venting assembly includes a piston cylinder 26 fixedly installed on the lower surface of the support plate 2. An air inlet pipe 29 is fixedly installed between the bottom end of the piston cylinder 26 and the reaction cylinder 3. The piston cylinder 26 is communicated with the inside of the annular groove through the air inlet pipe 29. A plurality of blades 23 are uniformly and fixedly installed on the outer circumference of the rotating ring 22. The air outlet of the air inlet pipe 29 is tangent to the outer circumference of the rotating ring 22. An exhaust pipe 30 passing through the top of the support plate 2 is fixedly installed on the outer surface of the reaction cylinder 3. The exhaust pipe 30 is communicated with the inside of the annular groove. A gas compression assembly is installed between the piston cylinder 26 and the pressing plate 13. The gas compression assembly includes a guide rod 27 fixedly installed on the lower surface of the pressing plate 13. The bottom end of the guide rod 27 passes through the lower surface of the support plate 2 and is fixedly installed with a movable plug 28. The movable plug 28 is slidably installed on the inner wall of the piston cylinder 26.

[0025] While the pressing plate 13 abuts against the inclined surface of the notch of the lower pressing ring 15 and moves downward, it will drive the guide rod 27 and the movable plug 28 to move downward, so that the movable plug 28 squeezes the gas in the piston cylinder 26 into the annular groove formed in the bottom wall of the reaction cylinder 3 through the air inlet pipe 29. Since the air outlet of the air inlet pipe 29 is tangent to the outer circumference of the rotating ring 22, the flow of the gas can blow the blades 23 to move, so that the rotating ring 22 can rotate quickly, and the hemispherical protrusions 24 installed on the top of the rotating ring 22 cooperate with the grooves formed on the lower surface of the annular vibrating piece 25 to make the annular vibrating piece 25 vibrate, so that the absorption liquid in the reaction cylinder 3 can vibrate accordingly, further splitting or eliminating the smoke bubbles in the absorption liquid, improving the contact efficiency between the bubbles and the reactants in the absorption liquid, and thus enhancing the effect of flue gas purification treatment.

[0026] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: during use, the flue gas and the absorbent liquid are connected to the rotary joint 5, so that the flue gas and the absorbent liquid enter the reaction cylinder 3 through the feed pipe 4, causing the flue gas and the absorbent liquid to react and purifying the flue gas; at the same time, the stepping motor 34 drives the transmission gear 33 to rotate, so that the transmission gear 33 drives the support disk 2 to rotate through the toothed ring 32 engaged with it, causing the support disk 2 to drive a plurality of reaction cylinders 3 to rotate synchronously with the corresponding pressure columns 11. When the pressing plate 13 disengages from the pressure sensor and abuts against the inclined surface of the notch of the lower pressing ring 15, the solenoid valve 10 installed on the corresponding feed pipe 4 closes, so that the corresponding reaction cylinder 3 stops feeding. The lower pressing ring 15 will push the pressing disk 12 downward through the pressing plate 13 and the pressure column 11, so that the extrusion disk 12 pressurizes the flue gas and the absorbent liquid in the reaction cylinder 3, increasing the density of the reactant molecules, increasing the collision frequency between the molecules, and increasing the reaction rate of the flue gas and the absorbent liquid, thereby accelerating the efficiency of flue gas purification treatment. Moreover, it can eliminate the bubbles generated by the flue gas in the absorbent liquid, preventing the flue gas in the bubbles from being discharged without participating in the flue gas purification treatment, resulting in incomplete flue gas purification treatment; When the pressing disk 12 moves downward, the guide post 20 installed at the end of the corresponding sealing block 17 will abut against the inner ring of the extrusion ring 21, causing the sealing block 17 to be pushed and blocking the discharge hole opened at the bottom of the reaction cylinder 3, making the inside of the reaction cylinder 3 a closed space for the pressing disk 12 to pressurize the flue gas and the absorbent liquid inside the reaction cylinder 3; While the pressing plate 13 abuts against the inclined surface of the notch of the lower pressing ring 15 and moves downward, it will drive the guide rod 27 and the movable plug 28 to move downward, so that the movable plug 28 squeezes the gas in the piston cylinder 26 into the annular groove opened on the bottom wall of the reaction cylinder 3 through the air inlet pipe 29. Since the air outlet of the air inlet pipe 29 is tangent to the outer circumference of the rotating ring 22, the flow of the gas can blow the blade 23 to move, so that the rotating ring 22 can rotate quickly. The hemispherical protrusion 24 installed on the top of the rotating ring 22 and the groove opened on the lower surface of the annular vibrating piece 25 can cause the annular vibrating piece 25 to vibrate, so that the absorbent liquid in the reaction cylinder 3 can vibrate accordingly, further splitting or eliminating the flue gas bubbles in the absorbent liquid, improving the contact efficiency between the bubbles and the reactants in the absorbent liquid, and thus enhancing the effect of flue gas purification treatment; As the support disk 2 continues to rotate, after the guide post 20 moves to the end of the extrusion ring 21 and separates from its inner ring, the sealing block 17 will reset under the elastic force of the spring rod 19, aligning the through hole 18 with the discharge hole opened at the bottom of the reaction cylinder 3, so that the reacted flue gas and absorbent liquid in the reaction cylinder 3 can be discharged. The gas after flue gas purification treatment passes through the air outlet hole 9 opened on the support disk 2 and is discharged through the air outlet pipe 8 installed at the top of the treatment tank 1. The absorbent liquid after participating in the reaction will be discharged through the discharge pipe 7; After the flue gas and the absorption liquid in the reaction cylinder 3 are drained, as the support disk 2 drives the continuous rotation of the reaction cylinder 3, the sealing assembly seals the discharge hole at the bottom of the reaction cylinder 3 again. At the same time, the pressurizing mechanism will reset upward under the elastic force of the return spring 14, so that the pressing plate 13 contacts the pressure sensor again, and the pressure sensor conducts the solenoid valve 10 on the corresponding feed pipe 4, so as to re-inject the flue gas and the absorption liquid into the reaction cylinder 3 for flue gas purification treatment; in this solution, the control mode of the electrical components is controlled by a peripheral controller matched with it, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in this field. Only its use is carried out without improvement, and the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection will not be explained in detail in the present invention.

[0027] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
