Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an environmental protection atmosphere cleaning device. Background Art

[0002] In the process of organic waste gas treatment, the scrubbing tower is often used as the front-end treatment equipment. It is improved on the basis of the floating packing layer gas purifier. It is widely used in the pretreatment of industrial waste gas treatment and dust removal. It has good purification effect and is often used in industrial waste gas purification and organic waste gas treatment. It is one of the basic treatment equipment in waste gas treatment.

[0003] A semiconductor plant washing tower is disclosed in Chinese patent publication No. CN116139681B. The semiconductor plant washing tower uses a demisting component to reduce the amount of water mist carried away by exhaust gas when it is discharged upward to pollute the environment.

[0004] However, compared with the existing technologies in related fields, most of the existing washing towers use conventional demisting layers to treat exhaust gas, which cannot effectively centrifuge out water molecules in the exhaust gas through the cyclone plate. There is still a large amount of water mist and water molecules in the air outlet, which cannot effectively meet the treatment standards, affecting production efficiency. At the same time, during operation, the gas flow rate will fluctuate. When the gas flow rate is large, the water molecules in the exhaust gas cannot be completely centrifuged out. When the gas flow rate is small, the gas cannot form a cyclone well, and the water molecules in the exhaust gas cannot be completely centrifuged out. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An embodiment of an environmental protection atmosphere cleaning device of the present invention is as follows Figures 1 to 9 As shown, it includes a tower body 1 for treating waste gas, and the interior of the tower body 1 is composed of an air inlet chamber 101, a first spray chamber 102, a second spray chamber 103, a first drying chamber 104 and a second drying chamber 105 from bottom to top. The first spray chamber 102 and the second spray chamber 103 are both provided with a spray assembly 2 for spraying waste gas washing liquid (a packing layer is provided below the spray assembly 2, and the packing layer is included in the spray assembly 2 in the present application). One side of the bottom of the tower body 1 is provided with a liquid supply assembly 3 for providing waste gas washing liquid to the two spray assemblies 2, an air outlet pipe 106 is provided at the top of the second drying chamber 105, and a demisting member 4 is provided inside the second drying chamber 105; a plurality of flow stabilizing components 5 for controlling the rising gas pressure are provided inside the first drying chamber 104. When the rising gas pressure is small, the gas gathers and accelerates the flow, ensuring that the gas can form a vortex in the second drying chamber 105, thereby completely centrifuging out water molecules in the waste gas.

[0022] like Figures 5 to 7 As shown, the flow stabilizing component 5 includes a lower tube section 501 and an upper tube section 502, the lower tube section 501 and the upper tube section 502 are connected through a constriction tube section 503, a vortex generating member 504 is slidably provided inside the lower tube section 501, and the vortex generating member 504 is composed of two spiral plates, and the tops of the two spiral plates are connected by a ring member, and a plurality of extrusion members 505 are fitted in the middle position of the outer surface of the constriction tube section 503, and the vortex generating member 504 and the plurality of extrusion members 505 are connected by a linkage component 6, as shown in FIG. Figure 2 and Figure 3 As shown, the first drying chamber 104 is fixedly installed with mounting plates 7 at positions corresponding to the upper tubes 502 and the lower tubes 501, and mounting holes 701 are opened at positions corresponding to the plurality of upper tubes 502 and the plurality of lower tubes 501. The upper tubes 502 and the lower tubes 501 are fixedly connected to the mounting holes 701. The end tube 503 is made of a flexible material, and the cross-sectional shape of the end tube 503 is an hourglass shape, as shown in FIG. Figure 6 and Figure 7 As shown, when the rising gas pressure is large, the vortex generating member 504 will slide upward due to the thrust of the gas, and then the linkage assembly 6 (such as Fig. 9 As shown in FIG. 5 ), the plurality of extrusion members 505 slide toward the outside of the constriction section tube 503, so that the inner diameter of the middle portion of the constriction section tube 503 becomes larger. When the rising gas pressure is small, the vortex generating member 504 slides downward due to its own gravity, and then the linkage assembly 6 (as shown in FIG. 5 ) is used. Fig. 9 As shown), multiple extrusion pieces 505 squeeze the constriction section tube 503, making the inner diameter of the middle part of the constriction section tube 503 smaller. When the gas enters the lower section tube 501, the vortex generating piece 504 will cause the gas to form a swirl, thereby using the swirl of the gas to separate part of the moisture in the gas. The constriction section tube 503 can increase the gas flow rate.

[0023] like Figures 5 to 9 As shown, the linkage assembly 6 includes a fixing plate 601 fixedly mounted on the outer surface of the upper tube 502, a mounting box 602 is fixedly mounted at the bottom end of the fixing plate 601, a gear shaft 603 is rotatably mounted inside the mounting box 602, a rotating hole is opened at the end of the mounting box 602 corresponding to the gear shaft 603, the end of the gear shaft 603 is matched and connected with the rotating hole through a bearing, a first rack 604 is slidably mounted on the mounting box 602 for transverse sliding and a second rack 605 is slidably mounted on the mounting box 602 for longitudinal sliding, one end of the second rack 605 is fixedly connected to the vortex generating member 504 (the second rack 605 is fixedly connected to the annular member), and one end of the first rack 604 is fixedly connected to the extrusion member 505 The first rack 604 is arranged below the gear shaft 603, and the second rack 605 is arranged outside the gear shaft 603. The first rack 604 and the second rack 605 are both meshed with the gear shaft 603. The second rack 605 is L-shaped. The lower tube 501 is provided with movable grooves 5011 at positions corresponding to the plurality of second racks 605. A sealing cover 606 for shielding the movable groove 5011 is fixedly provided on one side of the second rack 605 close to the movable groove 5011. A box cover 6021 is fixedly installed at the opening of the installation box 602. The installation box 602 is provided with sliding grooves 6022 at positions corresponding to the first rack 604 and the second rack 605. Figures 5 to 9As shown, when the gas contacts the vortex generating member 504, the vortex generating member 504 can monitor the pressure of the gas. On the one hand, when the rising gas pressure is large (the pressure increases with the large rising gas flow), the rising gas will cause the vortex generating member 504 to slide upward. When the vortex generating member 504 slides upward, the linkage assembly 6 is used (the second rack 605 causes the gear shaft 603 to rotate, so that the gear shaft 603 drives the first rack 604 to slide, so that the multiple extrusion members 505 slide toward the outside of the bundle-mouth section tube 503, so that the inner diameter of the middle position of the bundle-mouth section tube 503 becomes larger), and the multiple extrusion members 505 can gradually loosen the constraints on the bundle-mouth section tube 503 (that is, the diameter of the bundle-mouth section tube 503 will gradually increase (the bundle-mouth section tube 503 is made of elastic material), and then the speed of the gas passing through the bundle-mouth section tube 503 can be increased. On the other hand, when the rising gas pressure is small, the vortex generating member 504 can slide downward automatically by its own gravity, and then the linkage assembly 6 can be used to gradually allow the plurality of extrusion members 505 to press the bundle mouth section tube 503 (the second rack 605 will cause the gear shaft 603 to rotate in the opposite direction, so that the gear shaft 603 drives the first rack 604 to slide, so that the plurality of extrusion members 505 squeeze the bundle mouth section tube 503, and the inner diameter of the middle part of the bundle mouth section tube 503 becomes smaller), that is, the caliber of the bundle mouth section tube 503 will gradually decrease, so as to improve the gas gathering acceleration effect of the bundle mouth section tube 503, thereby ensuring that the gas can form a vortex inside the demister 4, and thus completely centrifuge out the water molecules in the exhaust gas (such as Figure 1 and Figure 2 as shown).

[0024] like Figure 1 and Figure 2 As shown, an air inlet pipe 107 is fixedly provided at the position of the tower body 1 corresponding to the air inlet chamber 101, and observation windows 8 are fixedly provided at the positions of the tower body 1 corresponding to the first spray chamber 102, the second spray chamber 103 and the first drying chamber 104. The observation windows 8 can facilitate the operator to intuitively understand the actual situation inside the tower body 1.

[0025] The spray assembly 2, packing layer, liquid supply assembly 3 and demisting element 4 described in the present application are well-known technologies in the technical field, so their working principles and detailed structures are not described. They are only described here without imposing any limitation.

[0026] The working process is as follows: S1, such as Figure 1 and Figure 2 As shown, when in use, the gas enters the air inlet chamber 101 through the air inlet pipe 107, and then passes through the first spray chamber 102, the second spray chamber 103, the first drying chamber 104 and the second drying chamber 105 in sequence and then is discharged through the air outlet pipe 106; S2, such as Figure 1 and Figure 2 As shown, when the gas enters the first spray chamber 102 and the second spray chamber 103, the two spray components 2 will spray the washing liquid into the packing layer, so that the exhaust gas is fully washed and the harmful substances in the exhaust gas are separated; S3 Figures 2 to 4 As shown, when the gas enters the first drying chamber 104, the gas will enter the interior of the multiple lower tubes 501, and then enter the second drying chamber 105 through the bundled tube 503 and the upper tube 502 in sequence; S4, such as Figures 5 to 7 As shown, when the gas enters the lower tube 501, the vortex generator 504 will cause the gas to form a swirl, so as to separate part of the water in the gas by using the swirl of the gas, and the constricted tube 503 can increase the gas flow rate (the Venturi effect is based on the principle of fluid mechanics. When a fluid (liquid or gas) passes through a pipe and the cross-section of a certain part of the pipe is reduced, the flow rate of the fluid will increase), ensuring that the gas can form a swirl again inside the demisting element 4, thereby completely centrifuging out the water molecules in the exhaust gas (such as Figure 2 shown); S5, such as Figures 6 to 9 As shown, when the gas contacts the vortex generating element 504, the vortex generating element 504 can monitor the pressure of the gas. When the rising gas pressure is large (the pressure increases with the large rising gas flow), the rising gas will cause the vortex generating element 504 to slide upward. When the vortex generating element 504 slides upward, the linkage component 6 is used (the second rack 605 causes the gear shaft 603 to rotate, so that the gear shaft 603 drives the first rack 604 to slide, so that the multiple extrusions 505 slide toward the outside of the bundle-mouth section tube 503, so that the inner diameter of the middle position of the bundle-mouth section tube 503 increases), the multiple extrusions 505 can gradually loosen the constraints on the bundle-mouth section tube 503 (that is, the diameter of the bundle-mouth section tube 503 will gradually increase (the bundle-mouth section tube 503 is made of elastic material), and then the speed of the gas passing through the bundle-mouth section tube 503 can be increased, thereby ensuring that the gas can form a vortex inside the defogger 4 well, and then completely centrifuge out the water molecules in the exhaust gas, as shown in FIG. Figure 2 shown); S6, such as Figures 6 to 9As shown, when the rising gas pressure is small, the vortex generating member 504 can slide downward automatically by its own gravity, and then the linkage assembly 6 can be used to gradually allow the multiple extrusion members 505 to press the bundle-mouth section tube 503 (the second rack 605 will cause the gear shaft 603 to rotate in the opposite direction, so that the gear shaft 603 drives the first rack 604 to slide, so that the multiple extrusion members 505 squeeze the bundle-mouth section tube 503, so that the inner diameter of the middle part of the bundle-mouth section tube 503 becomes smaller), that is, the diameter of the bundle-mouth section tube 503 will gradually decrease, thereby improving the gas gathering acceleration effect of the bundle-mouth section tube 503, thereby ensuring that the gas can form a vortex inside the defogger 4, and then completely centrifuge out the water molecules in the exhaust gas (such as Figure 2 shown); S7. Adaptive adjustment can be performed according to the rising pressure of the gas to ensure the flow speed of the gas, so that the gas can stably form a vortex inside the second drying chamber 105, thereby completely centrifuging out the water molecules in the exhaust gas, and the vortex generating element 504 will also cause the gas to form a vortex, thereby separating part of the moisture in the gas, effectively improving the processing standard of the equipment and avoiding affecting the production efficiency.
