Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas treatment and purification, in particular to a toxic and harmful gas treatment and purification equipment. BACKGROUND

[0002] Toxic and harmful gases refer to gases that exist in industrial production, laboratories or other environments and have direct or potential harm to human health or the environment. They are mainly divided into two categories: irritating gases and suffocating gases. These gases may have toxic, corrosive, flammable or explosive properties, and are commonly found in industries such as chemical, metallurgical, and mining. Flue gas, as a typical mixture of toxic and harmful gases, can cause irreversible damage to human health and the environment. In order to block the indiscriminate diffusion of toxic and harmful substances in flue gas from the source, it is necessary to purify and treat the flue gas to meet the standards before it can be discharged.

[0003] The existing toxic and harmful gas treatment and purification equipment generally uses nozzles to spray scrubbing liquid to contact the toxic and harmful substances in the flue gas. The toxic and harmful substances in the flue gas are dissolved in the scrubbing liquid or undergo chemical reactions with the scrubbing liquid. In this process, the particulate matter contained in the flue gas will adhere to the inner wall of the equipment under the influence of air flow changes and gravity. The conventional solution is to manually clean and maintain the equipment while it is stopped, which affects the efficiency of flue gas treatment and is not conducive to the purification and treatment of flue gas.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-10As shown, a toxic and harmful gas treatment and purification device includes a purification tank 1, a treatment tank 2 inside the purification tank 1, a support 3 fixedly connected to the bottom of the inner cavity of the treatment tank 2, a first heat-conducting cylinder 4 fixedly installed on the top of the support 3, a second heat-conducting cylinder 5 inside the first heat-conducting cylinder 4, and the bottom end of the second heat-conducting cylinder 5 connected to the support 3; a support plate 10 is disposed above the second heat-conducting cylinder 5, and a cleaning component 11 for cleaning adhering substances is provided at the bottom of the support plate 10. By setting the cleaning component 11, the machine can replace manual cleaning of the pollutants adhering to the surfaces of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, thereby reducing the overall cleaning frequency of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, improving the convenience of oil stain cleaning of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, and effectively reducing the impact of continuous pollutant adhesion on flue gas purification; the first heat-conducting cylinder 4 is provided with a cooling device for flue gas. The heat exchange component 6 is designed to cool the flue gas as it rises, facilitating subsequent flue gas purification. It also allows for the recovery and reuse of heat from the flue gas, thus achieving energy recycling. The bottom of the inner cavity of the purification tank 1 is equipped with an air inlet component 42 to facilitate flue gas input. This component allows external flue gas to be treated to be easily guided into the purification tank 1. The purification tank cover 33 is located at the top of the purification tank 1. Above the support plate 10, there is a mounting shell 12. Multiple first connecting rods 13 are symmetrically mounted on the outer side of the mounting shell 12. One end of each first connecting rod 13 is connected to the inner wall of the purification tank cover 33. Inside the mounting shell 12, there is a drive component 14 that provides rotational force to the cleaning component 11. This drive component 14 allows the cleaning component 11 to perform cleaning work on the surfaces of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, removing contaminants.

The flue gas will enter the interior of the purification tank 1 through the flue gas inlet 422. It should be noted that the flue gas inlet 422 is located below the flue gas inlet pipe 421 to prevent the detergent liquid from falling into the interior of the flue gas inlet pipe 421 and avoid affecting the flue gas input process.

[0036] The heat exchange assembly 6 includes a first heat exchange tube 62 disposed below one side of the support 3, and a second heat exchange tube 63 disposed below the other side of the support 3.

Figure 2 , Figure 4 , Figure 6 and Figure 10 As shown, in actual use, the first heat exchange tube 62 is connected to the external cold water supply pipe, and the second heat exchange tube 63 is connected to the water tank. After the external cold water enters the spiral coil 61 through the first heat exchange tube 62 and the first connecting pipe 64, it will carry away the heat from the first heat conduction cylinder 4 and the second heat conduction cylinder 5 along the way. Then, the water that has absorbed heat returns to the inside of the water tank through the second heat exchange tube 63 and the second connecting pipe 65, thereby cooling the flue gas and facilitating subsequent flue gas purification. At the same time, the heat of the flue gas can be recovered and reused, realizing the recovery and reuse of energy.

The flue gas will pass through multiple guide grooves 9 inside the first heat-conducting plate 7 and the second heat-conducting plate 8, which is conducive to improving the heat exchange effect and heat exchange efficiency of the flue gas.

[0038] The bottom of the purification tank 1 is provided with a support platform 36, which is connected to the purification tank 1 by bolts. A purification tank base 39 is fixedly connected to the bottom of the support platform 36.

The top of the support rods 38 are connected to the support platform 36. Figure 1 , Figure 2 and Figure 3 As shown, the vapor generated by the contact between the flue gas and the detergent condenses and falls into the purification tank base 39 along the inner wall of the purification tank 1. Then, the waste liquid is discharged into the external waste liquid pool through the drain port 40 and the drain bend 41 to facilitate the subsequent waste liquid sedimentation and filtration.

[0039] The top of the purification tank cover 33 is provided with an exhaust port 34, and the top of the exhaust port 34 is provided with an exhaust bend 35. The purification tank cover 33 is connected to the purification tank body 1 by bolts. Figure 1 , Figure 2 and Figure 3 As shown, by setting the exhaust port 34 and the exhaust bend 35, the purified flue gas can be output to the outside, which facilitates the subsequent secondary purification treatment of the flue gas.

[0040] The cleaning assembly 11 includes a limiting cylinder 113 disposed inside the first heat-conducting cylinder 4. Second metal bristles 114 are fixedly connected to both the outer and inner walls of the limiting cylinder 113.

A positioning post 111 is disposed inside the second heat-conducting cylinder 5. First metal bristles 112 are fixedly connected to the outer wall of the positioning post 111, and a first drive shaft 115 is fixedly connected to the top end of the positioning post 111. The top end of the first drive shaft 115 is connected to the support plate 10. Figure 2 , Figure 6 and Figure 9 As shown, the limiting cylinder 113 and positioning column 111 can drive the first metal brush 112 and the second metal brush 114 to replace manual cleaning of the contaminants attached to the surface of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5. This helps to reduce the overall cleaning frequency of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, improves the convenience of cleaning the oil stains on the first heat-conducting cylinder 4, and can effectively reduce the impact of continuous contaminant adhesion on the flue gas purification treatment.

[0041] The drive assembly 14 includes a bushing 141 rotatably connected to the bottom of the inner cavity of the mounting housing 12. A hollow tube 142 is rotatably connected inside the bushing 141.

A drive motor 145 is fixedly installed on one side of the inner wall of the mounting housing 12. A driving bevel gear 146 is fixedly installed at the output end of the drive motor 145. The driving bevel gear 146 meshes with the first driven bevel gear 143 and the second driven bevel gear 144, respectively. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the drive motor 145 can drive the active bevel gear 146 to rotate. Then, the active bevel gear 146 drives the bushing 141 and the hollow tube 142 to rotate in opposite directions through the first driven bevel gear 143 and the second driven bevel gear 144, thereby driving the cleaning component 11 to perform the cleaning work on the contaminants attached to the surface of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5.

[0042] A rotary joint 15 is provided at the top of the inner cavity of the mounting shell 12. Second connecting rods 17 are fixedly connected to both sides of the rotary joint 15. One end of the second connecting rod 17 is connected to the inner wall of the mounting shell 12. The top end of the hollow tube 142 is connected to the rotary joint 15. A washing liquid inlet pipe 16 is connected to the top end of the rotary joint 15. One end of the washing liquid inlet pipe 16 extends to the outside of the purification tank cover 33. A washing liquid channel 18 is provided inside the support plate 10. A first annular cavity 19 is provided on one side of the washing liquid channel 18. First nozzles 21 are symmetrically installed on the outer side of the first annular cavity 19. A second annular cavity 20 is provided on the other side of the washing liquid channel 18. Second nozzles 22 are symmetrically installed at the bottom of the second annular cavity 20. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the external washing liquid enters the first annular cavity 19 and the second annular cavity 20 sequentially through the washing liquid inlet pipe 16, the rotary joint 15, the hollow tube 142, and the washing liquid channel 18. Then, the washing liquid is sprayed onto the flue gas from top to bottom through the second nozzle 22. The washing liquid washes away the dirt swept off the first metal brush bristles 112 and the second metal brush bristles 114. At the same time, the first metal brush bristles 112 and the second metal brush bristles 114 slow down the falling speed of the washing liquid, which is conducive to the full contact between the washing liquid and the flue gas.

[0043] Multiple strip seats 23 are symmetrically installed on the outer side of the bottom end of the bushing 141. One end of each strip seat 23 is rotatably connected to a second drive shaft 24. A quadrilateral frame 25 is fixedly installed on the outer side of the second drive shaft 24. Multiple adsorption strips 32 are symmetrically installed on both sides of the inner wall of the quadrilateral frame 25. The support plate 10 has a receiving groove 26 inside. A gear ring 28 is fixedly connected to the inner wall of the receiving groove 26. An annular seat 31 is provided below the support plate 10. The top end of the second drive shaft 24 passes through the receiving groove 26 and is fixedly connected to a drive gear 27. One side of the drive gear 27 meshes with the gear ring 28. A slider 29 is fixedly installed on the top of the annular seat 31. A groove 30 corresponding to the slider 29 is opened at the bottom of the support plate 10. The slider 29 is located inside the groove 30. Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the flue gas after preliminary purification enters the interior of the purification tank cover 33. Then, the drive assembly 14 drives the bushing 141 to rotate. The bushing 141 then drives multiple strip seats 23 to continuously shift and change positions. Under the action of the gear ring 28 and the transmission gear 27, the quadrilateral frame 25 at the bottom of the second transmission shaft 24 can continuously rotate. Multiple adsorption strips 32 on the inner wall of the quadrilateral frame 25 will continuously capture the pollutants remaining in the flue gas during the rotation, thereby further improving the purification effect of the flue gas. It should be noted that the adsorption strips 32 are made of activated carbon or ceramic materials. The adsorption strips 32 made of activated carbon or ceramic materials can effectively adsorb and capture pollutants in the flue gas.

[0044] Working principle: First, the air intake component 42 allows the external flue gas to be treated to be easily guided into the purification tank 1. Then, the heat exchange component 6 cools the flue gas as it rises, facilitating subsequent purification. Simultaneously, it recovers and reuses the heat from the flue gas, achieving energy recovery and reuse. After heat recovery is complete, external scrubbing liquid is sprayed onto the flue gas from top to bottom through the second nozzle 22, dissolving or reacting with toxic and harmful substances in the flue gas. The washing liquid undergoes a chemical reaction, and through the drive component 14 and the cleaning component 11, the machine can replace manual labor to clean the contaminants attached to the surfaces of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5. This helps to reduce the overall cleaning frequency of the first heat-conducting cylinder 4 and the second heat-conducting cylinder 5, improves the convenience of cleaning the oil stains on the first heat-conducting cylinder 4, and can effectively reduce the impact of continuous contaminant adhesion on the flue gas purification process. At the same time, the first metal bristles 112 and the second metal bristles 114 will slow down the falling speed of the washing liquid, which is conducive to the full contact between the washing liquid and the flue gas.
