Description

Technical Field

[0001] The present invention belongs to the technical field of gas processing, and in particular relates to a gas processing device and a processing method thereof. Background Art

[0002] Carbon dioxide (CO2) waste gas is increasingly polluting the atmosphere. Excessive and unrestricted CO2 emissions from various industrial processes are causing a catastrophic greenhouse effect in the atmosphere, with potentially catastrophic consequences for the human environment. On the other hand, CO2 is a valuable carbon resource, finding widespread use in a wide range of sectors, including chemical engineering, machinery, food, and agriculture. Therefore, the recovery, purification, and reuse of CO2 from various industrial waste gases has become a growing concern. The United Nations Framework Convention on Climate Change and my country's energy conservation and emission reduction policies demonstrate the importance and urgency of controlling CO2 emissions and recycling worldwide.

[0003] The current technologies for recovering carbon dioxide from industrial waste gas include chemical absorption, adsorption, cryogenic separation, and membrane separation. Among them, the most widely used is chemical absorption, which uses sodium hydroxide solution to contact with air to absorb carbon dioxide in the air. However, in the existing chemical absorption method, after the industrial waste gas is passed into the sodium hydroxide solution, because the sodium hydroxide solution is generally in a static state, the industrial waste gas will quickly pass through the sodium hydroxide solution, resulting in insufficient time for the carbon dioxide to react with the sodium hydroxide solution. As a result, the discharged industrial waste gas still carries a large amount of carbon dioxide.

[0004] To this end, the present invention provides a gas processing device and a processing method thereof. Summary of the Invention

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 10As shown, the present invention provides a technical solution, a gas processing device, including a box body 1, the inner wall of the box body 1 is fixedly connected to an air intake pipe 2, one end of the air intake pipe 2 extends to the outside of the box body 1, and an air outlet 3 is opened on the top of the box body 1. Two guide blocks 4 are symmetrically fixedly connected to the top of the inner wall of the box body 1, and the bottoms of the two guide blocks 4 are both set as inclined surfaces. The inner walls of the two guide blocks 4 are rotatably connected to liquid outlet pipes 5, and the outer walls of the liquid outlet pipes 5 are provided with a plurality of evenly distributed nozzles 6. One end of the two liquid outlet pipes 5 passes through the box body 1. The outer wall is provided with a driving assembly for use with the liquid outlet pipe 5. The outer wall of the box body 1 is fixedly connected to a water pump 9. The output end of the water pump 9 is fixedly connected to a first connecting pipe 10. One end of the first connecting pipe 10 extends to the interior of the box body 1. The other end of the first connecting pipe 10 is fixedly connected to a second connecting pipe 11. The two ends of the second connecting pipe 11 are respectively rotatably connected to the two liquid outlet pipes 5. A stopper 7 is fixedly connected to the inner wall of the box body 1 and located between the two guide blocks 4. Arc grooves 8 are provided on both sides of the stopper 7, and the bottom of the stopper 7 is set to be concave.

[0038] Through the above technical solution, sodium hydroxide solution is loaded into the interior of the box 1, and the industrial waste gas is introduced into the box 1 from the air inlet pipe 2, reacting with the sodium hydroxide solution in the box 1 to remove the carbon dioxide inside. After passing through the sodium hydroxide solution, the industrial waste gas flows upward, and the two guide blocks 4 are set to make the circulation range of the industrial waste gas more concentrated. The water pump 9 is started to pump the sodium hydroxide solution in the box 1 along the first connecting pipe 10 and the second connecting pipe 11 to the liquid outlet pipe 5, and sprayed out through the nozzle 6 to spray the industrial waste gas between the two guide blocks 4. The sodium hydroxide solution is sprayed by the nozzle 6, and the sodium hydroxide solution is sprayed by the nozzle 6. At the same time, the nozzle 6 is driven by the driving component to swing up and down, so that the spraying range of the sodium hydroxide solution is larger, and the industrial waste gas is prevented from directly passing through the sodium hydroxide solution. The upward-flowing industrial waste gas is blocked by the set block 7 to prevent the industrial waste gas from passing through the two guide blocks 4 too quickly. The sodium hydroxide solution sprayed by the nozzle 6 is sprinkled on the block 7 and flows downward along the block 7 to form a water curtain, which can further react with the passing industrial waste gas.

[0039] Specifically, a fixing frame 20 is fixedly connected to the inner wall of the box body 1 and located below the guide block 4. The bottom of the fixing frame 20 is set to a symmetrical inclined surface. Two liquid accumulation grooves 27 are symmetrically opened on the top of the fixing frame 20. Two cavities 24 are symmetrically opened inside the fixing frame 20. A first ventilation port 25 is opened inside the fixing frame 20 and located at the top of the cavity 24. A connecting groove 26 is opened inside the fixing frame 20 and located between the liquid accumulation groove 27 and the first ventilation port 25. The connecting groove 26 is opened at an angle.

[0040] Through the above technical solution, the sprayed sodium hydroxide solution enters the two liquid accumulation tanks 27. When the water surface of the sodium hydroxide solution in the liquid accumulation tank 27 is flush with the top of the connecting tank 26, the sodium hydroxide solution falls along the first vent 25 and enters the cavity 24. After filling the cavity 24, it flows to the bottom of the box 1 for storage. The sodium hydroxide solution entering the liquid accumulation tank 27 blocks the first vent 25, preventing the industrial waste gas from directly passing through the liquid accumulation tank 27. As the industrial waste gas in the box 1 enters, the pressure of the industrial waste gas in the box 1 will increase, thereby increasing the number of carbon dioxide molecules per unit volume, and increasing the frequency of collision with the sodium hydroxide solution, thereby accelerating the reaction rate. When the pressure of the industrial waste gas in the box 1 increases, it can break through the obstruction of the sodium hydroxide solution in the liquid accumulation tank 27 and flow upward. After entering the liquid accumulation tank 27, the industrial waste gas can merge with the sodium hydroxide solution in the liquid accumulation tank 27, thereby enhancing the contact between the industrial waste gas and the sodium hydroxide solution.

[0041] Specifically, two motors 21 are symmetrically fixedly connected to the outer wall of the box body 1, and the output ends of the two motors 21 extend to the interior of the two cavities 24 respectively and are fixedly connected to the rotating rod 41. The outer wall of the rotating rod 41 is equidistantly fixedly connected to six blades 22, and the six blades 22 are all arranged in an arc shape. The outer walls of the six blades 22 are fixedly connected to an extension plate 23.

[0042] Through the above technical solution, the liquid level of the sodium hydroxide solution loaded in the box 1 is level with the rotating rod 41, and the two motors 21 are started. The motor 21 on the right drives the corresponding rotating rod 41 to rotate counterclockwise, and the motor 21 on the left drives the corresponding rotating rod 41 to rotate clockwise. While the rotating rod 41 rotates, it drives the six blades 22 to rotate in the cavity 24. When the industrial waste gas passes through the sodium hydroxide solution, it enters the concave surface of the blade 22. Under the wrapping of the concave surface of the blade 22, as the blade 22 rotates, the industrial waste gas can be beaten back into the sodium hydroxide solution, so that the industrial waste gas continues to react with the sodium hydroxide solution, preventing the industrial waste gas from passing through the sodium hydroxide solution too quickly. By setting the extension plate 23, the wrapping effect of the blade 22 on the industrial waste gas can be improved, so that more industrial waste gas can be beaten into the sodium hydroxide solution while the blade 22 rotates.

[0043] Specifically, two side panels 31 are symmetrically fixedly connected to the top of the air intake duct 2, and a plurality of inclined panels 32 are equidistantly fixedly connected between the two side panels 31. The inclination angles of the plurality of inclined panels 32 increase successively from the middle to the two sides. Two spoilers 33 are symmetrically fixedly connected to the top of the inclined panels 32, and both spoilers 33 are configured to be in a roll shape.

[0044] Through the above technical solution, the industrial waste gas transported from the air intake pipe 2 enters between the two side plates 31, and is separated by multiple inclined plates 32, so that the industrial waste gas forms multiple streams and flows upward, thereby preventing the industrial waste gas from entering the box body 1 and agglomerating into a mass, which makes it difficult for the internal industrial waste gas to contact the sodium hydroxide solution. The industrial waste gas passing through the inclined plate 32 enters the baffle plate 33, and is blocked by the baffle plate 33, thereby extending the residence time of the industrial waste gas in the sodium hydroxide solution, giving the industrial waste gas and the sodium hydroxide solution sufficient reaction time.

[0045] Specifically, two second guide plates 34 are symmetrically fixedly connected to the inner wall of the box body 1 and located between the fixing frame 20 and the baffle 33. The two second guide plates 34 are both inclined upward. Several second baffles 35 are equidistantly arranged at the top of the second guide plate 34 and the bottom of the fixing frame 20. The second baffles 35 are arranged in an arc shape.

[0046] Through the above technical solution, the upward-emerging industrial waste gas is blocked by the obliquely installed second guide plate 34, so that the industrial waste gas flows to both sides along the inclined surface of the second guide plate 34, thereby extending the flow path of the industrial waste gas in the sodium hydroxide solution, and further extending the reaction time of the industrial waste gas and the sodium hydroxide solution. After passing through the second guide plate 34, the industrial waste gas flows between the second guide plate 34 and the fixed frame 20. The two sets of second baffles 35 are provided to further extend the flow path of the industrial waste gas in the sodium hydroxide solution, so that the industrial waste gas can fully react with the sodium hydroxide solution.

[0047] Specifically, the inner wall of the fixing frame 20 is fixedly connected with a horizontal plate 28, and a number of second ventilation holes 29 are equidistantly provided inside the horizontal plate 28. The inner wall of the box body 1 and above each second ventilation hole 29 are fixedly connected with a diverter block 30, and the bottom of the diverter block 30 is set as a symmetrical inclined surface.

[0048] Through the above technical solution, the industrial waste gas is blocked by the horizontal plate 28, and the industrial waste gas flows upward through the plurality of second vents 29, making the industrial waste gas more dispersed, and under the cutting of the plurality of diversion blocks 30, the industrial waste gas is formed into a plurality of small air masses, thereby preventing the sodium hydroxide solution from coming into contact with the interior of the industrial waste gas.

[0049] Specifically, the bottoms of the two guide blocks 4 are fixedly connected with an arc-shaped plate 12, one end of the two arc-shaped plates 12 is fixedly connected with a first drain plate 14, the two first drain plates 14 are both installed at an angle, a first drain port 13 is opened inside the arc-shaped plate 12, and a plurality of second drain ports 15 are opened equidistantly inside the first drain plate 14. The top of the first drain plate 14 is fixedly connected with a plurality of first baffles 16 equidistantly, and the first baffles 16 are located on the side of the second drain port 15. The bottom of the first drain plate 14 is fixedly connected with a plurality of guide plates 17 equidistantly, and the guide plates 17 are located on the side of the second drain port 15.

[0050] Through the above technical solution, the sodium hydroxide solution sprayed by the nozzle 6 falls on the two first guide plates 14, and the sodium hydroxide solution is guided by the two first guide plates 14. The sodium hydroxide solution slides down the slope of the first guide plates 14. When passing through the second drain port 15, part of the sodium hydroxide solution falls along the second drain port 15 under the obstruction of the first baffle 16. The sodium hydroxide solution falling from the second drain port 15 is guided by the guide plate 17 to form a water curtain, and the remaining sodium hydroxide solution falls from the first drain port 13 in the curved plate 12. The industrial waste gas flowing upward is blocked by the multiple sodium hydroxide solution water curtains. The industrial waste gas can further react with the sodium hydroxide solution when passing through the multiple sodium hydroxide solution water curtains.

[0051] Specifically, the top of the fixing frame 20 is fixedly connected with a guide block 18, the top of the guide block 18 is set as a symmetrical inclined surface, and a number of extension blocks 19 are fixedly connected to the inclined surface of the guide block 18 at equal intervals, the top of the extension block 19 is set as an inclined surface, and the side of the extension block 19 is set as a concave shape.

[0052] Through the above technical solution, the sprayed sodium hydroxide solution can enter the liquid accumulation tank 27 along the inclined surface of the guide block 18, and be blocked by the concave surfaces of several extension blocks 19, thereby slowing down the upward flow speed of the industrial waste gas. When the sodium hydroxide solution slides down on the guide block 18, it passes through the drop caused by several extension blocks 19 and can form multiple water curtains again to further react with the industrial waste gas.

[0053] Specifically, the driving assembly includes a slide 38, which is arranged on the outer wall of the box body 1 and is slidingly connected to the box body 1. One end of the two rotating rods 41 passes through the box body 1 and is fixedly connected to the crank 36. The outer walls of the two cranks 36 are rotatably connected to the connecting shaft 37. The two connecting shafts 37 are rotatably connected to the slide 38. The other ends of the two liquid outlet pipes 5 pass through the box body 1 and are fixedly connected to the gear 40. The top of the slide 38 is symmetrically fixedly connected to two racks 39, and the two racks 39 are respectively meshed with the two gears 40.

[0054] Through the above technical solution, the rotating rod 41 drives the crank 36 to rotate while rotating. When the end of the crank 36 rotates to the upper side, the sliding plate 38 is pushed upward through the provided connecting shaft 37, so that the two racks 39 move upward at the same time, driving the two gears 40 to rotate one counterclockwise and the other clockwise, so that the two groups of nozzles 6 swing downward at the same time. When the end of the crank 36 rotates to the lower side, the sliding plate 38 is pulled downward through the provided connecting shaft 37, so that the two racks 39 move downward at the same time, driving the two groups of nozzles 6 to swing upward at the same time. In this way, the rotating rod 41 can drive the two groups of nozzles 6 to swing back and forth up and down while rotating, so that the spraying range of the sodium hydroxide solution is larger, and industrial waste gas is prevented from directly passing through the sodium hydroxide solution.

[0055] A method for treating a gas treatment device is provided. The method is applicable to the above-mentioned gas treatment device. The steps of the method are as follows:

[0056] S1: Sodium hydroxide solution is placed in the box 1 so that the liquid level of the sodium hydroxide solution is level with the rotating rod 41, and industrial waste gas is introduced into the box 1 through the air inlet pipe 2 to react with the sodium hydroxide solution in the box 1;

[0057] S2: Start the water pump 9 to pump the sodium hydroxide solution in the tank 1 along the first connecting pipe 10 and the second connecting pipe 11 to the liquid outlet pipe 5, and spray it out through the nozzle 6. Cooperate with the drive component to make the nozzle 6 swing back and forth;

[0058] S3: Start the motor 21 to drive the blades 22 to rotate in the cavity 24, and beat the emitted industrial waste gas back into the sodium hydroxide solution.

[0059] When in use, sodium hydroxide solution is loaded into the interior of the box body 1, and the liquid level of the sodium hydroxide solution is level with the rotating rod 41. The industrial waste gas is introduced into the box body 1 from the air inlet pipe 2, reacts with the sodium hydroxide solution in the box body 1, and removes the internal carbon dioxide. The water pump 9 is started, and the sodium hydroxide solution in the box body 1 is pumped along the first connecting pipe 10 and the second connecting pipe 11 to the liquid outlet pipe 5, and sprayed out through the nozzle 6. The upward-flowing industrial waste gas is blocked by the set block 7 to prevent the industrial waste gas from passing through the two guide blocks 4 too quickly. The sodium hydroxide solution sprayed from the nozzle 6 is sprinkled on the block 7 and flows downward along the block 7 to form a water curtain, which can further react with the industrial waste gas passing through. The sodium hydroxide solution sprayed by the nozzle 6 falls on the two first On a guide plate 14, the sodium hydroxide solution is guided by two first guide plates 14, and the sodium hydroxide solution slides down along the slope of the first guide plate 14. When passing through the second drain port 15, part of the sodium hydroxide solution falls along the second drain port 15 under the obstruction of the first baffle 16. The sodium hydroxide solution falling from the second drain port 15 is guided by the guide plate 17 to form a water curtain, and the remaining sodium hydroxide solution falls from the first drain port 13 in the arc plate 12. The upward flowing industrial waste gas is blocked by the multiple sodium hydroxide solution water curtains. The industrial waste gas can further react with the sodium hydroxide solution when passing through the multiple sodium hydroxide solution water curtains. The upward flow speed of the industrial waste gas is slowed down by the obstruction of the concave surfaces of the several extension blocks 19, and When the sodium hydroxide solution slides down on the guide block 18, it passes through the drop caused by several extension blocks 19, which can form multiple water curtains again to further react with the industrial waste gas. The industrial waste gas transported from the air inlet pipe 2 enters between the two side plates 31 and is separated by multiple inclined plates 32, so that the industrial waste gas forms multiple streams to flow upward, thereby preventing the industrial waste gas from entering the box body 1 and agglomerating into a mass, which makes it difficult for the internal industrial waste gas to contact the sodium hydroxide solution. The industrial waste gas passing through the inclined plate 32 enters the baffle plate 33 and is blocked by the baffle plate 33, thereby extending the residence time of the industrial waste gas in the sodium hydroxide solution and giving the industrial waste gas and the sodium hydroxide solution sufficient reaction time. The industrial waste gas emerging upward is blocked by the second guide plate 34 installed at an angle, so that the industrial waste gas is discharged along the The industrial waste gas flows to both sides along the inclined surface of the second guide plate 34, thereby extending the flow path of the industrial waste gas in the sodium hydroxide solution and further extending the reaction time of the industrial waste gas and the sodium hydroxide solution. After passing through the second guide plate 34, the industrial waste gas flows between the second guide plate 34 and the fixed frame 20. The two sets of second baffles 35 are provided to further extend the flow path of the industrial waste gas in the sodium hydroxide solution, so that the industrial waste gas can fully react with the sodium hydroxide solution. The industrial waste gas is blocked by the horizontal plate 28, and the industrial waste gas flows upward through the plurality of second vents 29, making the industrial waste gas more dispersed. Under the cutting of the plurality of diverter blocks 30, the industrial waste gas forms a plurality of small air clusters, thereby preventing the sodium hydroxide solution from coming into contact with the interior of the industrial waste gas.Start the two motors 21. The motor 21 on the right drives the corresponding rotating rod 41 to rotate counterclockwise, and the motor 21 on the left drives the corresponding rotating rod 41 to rotate clockwise. When the rotating rod 41 rotates, it drives the six blades 22 to rotate in the cavity 24. When the industrial waste gas passes through the sodium hydroxide solution and enters the inner concave surface of the blade 22, the industrial waste gas can be re-beaten into the sodium hydroxide solution as the blade 22 rotates, so that the industrial waste gas continues to react with the sodium hydroxide solution, preventing the industrial waste gas from passing through the sodium hydroxide solution too quickly. 3. It can improve the wrapping effect of the blades 22 on the industrial waste gas, so that more industrial waste gas can be beaten into the sodium hydroxide solution while the blades 22 rotate, and the sprayed sodium hydroxide solution enters the two liquid sump tanks 27. When the water surface of the sodium hydroxide solution in the liquid sump tank 27 is flush with the top of the connecting tank 26, the sodium hydroxide solution falls along the first vent 25 and enters the cavity 24. After filling the cavity 24, it flows to the bottom of the box 1 and accumulates. The sodium hydroxide solution entering the liquid sump tank 27 blocks the first vent 25, preventing the industrial waste gas from directly passing through the liquid sump tank 27. The entry of industrial waste gas into the box 1 will increase the pressure of the industrial waste gas in the box 1, thereby increasing the number of carbon dioxide molecules per unit volume and increasing the frequency of collision with the sodium hydroxide solution, thereby accelerating the reaction rate. When the pressure of the industrial waste gas in the box 1 is increased, it can break through the obstruction of the sodium hydroxide solution in the liquid sump 27 and flow upward. After entering the liquid sump 27, the industrial waste gas can blend with the sodium hydroxide solution in the liquid sump 27, thereby improving the contact between the industrial waste gas and the sodium hydroxide solution. The rotation of the rotating rod 41 drives the crank 36 to rotate. When the end of the crank 36 rotates to the top, the industrial waste gas is discharged through the rotating rod 41. The connecting shaft 37 pushes the slide 38 upward, causing the two racks 39 to move upward simultaneously, driving the two gears 40 to rotate one counterclockwise and the other clockwise, causing the two sets of nozzles 6 to swing downward simultaneously. When the end of the crank 36 rotates downward, the connecting shaft 37 pulls the slide 38 downward, causing the two racks 39 to move downward simultaneously, driving the two sets of nozzles 6 to swing upward simultaneously. This reciprocating movement, while the rotating rod 41 rotates, can also drive the two sets of nozzles 6 to swing back and forth, expanding the spray range of the sodium hydroxide solution and preventing industrial waste gas from directly passing through the sodium hydroxide solution.
