Description

Technical Field

[0001] This application relates to the field of waste gas treatment, and in particular to a horizontal high-efficiency spray system for acid and alkali waste gas. Background Technology

[0002] Spray scrubbing towers are common waste gas purification and treatment equipment, and are also commonly used in many factories.

[0003] Currently, the exhaust gas enters the scrubbing tower through the inlet at the bottom and flows upwards evenly under the power of the fan. The scrubbing tower contains a packing layer, above which a horizontal spray pipe is installed. Multiple nozzles are evenly spaced on the spray pipe, spraying the chemical solution evenly onto the packing layer. The exhaust gas reacts with the chemical solution after passing through the packing layer, and after further demisting, it is discharged from the outlet at the top of the scrubbing tower.

[0004] After prolonged use, nozzles are prone to clogging, leakage, and spray flow deviation. In such cases, the scrubbing tower needs to be shut down first, and then the nozzles need to be repaired or replaced. At the same time, since multiple nozzles are evenly distributed in the scrubbing tower along the horizontal direction, the nozzles located in the center of the scrubbing tower are difficult to replace, which greatly increases the nozzle replacement time and consequently leads to a significant decrease in the efficiency of waste gas purification. Summary of the Invention

[0005] In order to improve the problem of reduced efficiency in waste gas purification due to the difficulty in nozzle maintenance and replacement, this application provides a horizontal high-efficiency spray system for acid and alkali waste gas and water.

[0006] The horizontal acid and alkali waste gas and water high-efficiency spray system provided in this application adopts the following technical solution:

[0007] A horizontal high-efficiency acid and alkali waste gas and water spraying system includes a tower body with an inlet pipe and an outlet pipe at both ends. A packing layer is installed inside the tower body. A spraying mechanism is installed on the tower body, comprising a pressure supply component, a main liquid supply pipe, multiple branch liquid supply pipes, and nozzles. The pressure supply component is installed on the tower body. The main liquid supply pipe is installed on the tower body and connected to the pressure supply component. Multiple shut-off valves are installed on the main liquid supply pipe. Each branch liquid supply pipe is detachably installed at the end away from the main liquid supply pipe via quick-release couplings. Multiple nozzles are installed at multiple output ends of the branch liquid supply pipes and located above the packing layer inside the tower body.

[0008] By adopting the above technical solution, when purifying waste gas, the waste gas enters the tower body through the inlet pipe. The pressure supply unit delivers the liquid medicine through the main supply pipe to multiple supply branch pipes. The nozzles then spray the liquid medicine into the packing layer. The waste gas is purified after passing through the packing layer and is then discharged through the outlet pipe. When a nozzle malfunctions and needs repair or replacement, the shut-off valve is closed to stop the liquid supply to the faulty supply branch pipe. The supply branch pipe is then removed from the main supply pipe using a quick-release connector, allowing the nozzle to be removed from the tower body. After the nozzle is repaired or replaced, the supply branch pipe is reinstalled on the main supply pipe, and the shut-off valve is opened. This setup allows for easy removal of the nozzle from the tower body during repair or replacement, significantly reducing the difficulty and speed of nozzle repair and replacement. Furthermore, the shut-off valve stops the liquid supply to the faulty supply branch pipe, eliminating the need to shut down the scrubbing unit during nozzle repair or replacement, thereby improving the efficiency of waste gas purification.

[0009] Preferably, the top of the tower body is provided with a plurality of seats with top openings, the opening ends of the seats are sealed and abutted by a cover plate, the plurality of output ends of the liquid supply branch pipe are sealed through the cover plate, and the cover plate is provided with a plurality of quick-release components for fixing and unfixing the cover plate to the seat body.

[0010] By adopting the above technical solution, during the exhaust gas evolution process, the cover plate is sealed against the base, making it difficult for the exhaust gas to leak from the tower body. When it is necessary to disassemble the liquid supply branch pipe to repair or replace the nozzle, the quick-release assembly is used to release the fixation between the cover plate and the base body, and the liquid supply branch pipe can then drive the nozzle out of the tower body.

[0011] Preferably, the quick-release assembly includes a fixing part fixedly mounted on the base and a snap-fit ​​part rotatably mounted on the cover plate. The fixing part has a snap-fit ​​groove, and the outer side of the snap-fit ​​part is gradually inclined from low to high to form an arc-shaped ramp. The arc-shaped ramp is rotatably mounted in the snap-fit ​​groove. When the high end of the arc-shaped ramp rotates into the snap-fit ​​groove, the snap-fit ​​part is fixedly connected to the fixing part. The snap-fit ​​part has a flat wall near the low end of the arc-shaped ramp for separating the snap-fit ​​part from the fixing part.

[0012] By adopting the above technical solution, when using the quick-release assembly to unfasten the cover plate and the base, rotating the locking part causes the lower end of the arc-shaped ramp to rotate into the slot, thus releasing the fixation between the locking part and the fixing part. Continuing to rotate the locking part makes the flat wall parallel to the fixing part. At this time, the flat wall causes the locking part to avoid the fixing part, allowing the cover plate to be removed from the base. When using the quick-release assembly to fix the cover plate and the base, rotating the locking part causes the upper end of the arc-shaped ramp to rotate into the slot. At this time, the arc-shaped ramp and the slot form a locking fixation, thus fixing the locking part and the fixing part, thereby fixing the cover plate to the base.

[0013] Preferably, a first handle is fixedly provided on the snap-fit ​​part.

[0014] By adopting the above technical solution, the first handle drives the locking part to rotate, thereby facilitating the fixing and unfixing of the locking part and the fixing part.

[0015] Preferably, the multiple quick-release components are spaced apart along the length of the liquid supply branch pipe, and a synchronizing rod is provided at the end of the top wall of the first handle away from the locking part along the length of the liquid supply branch pipe, and the synchronizing rod is rotatably connected to the multiple first handles.

[0016] By adopting the above technical solution, when fixing or disengaging the fixing part and the snap-fit ​​part, rotating one first handle causes the first handle to move the synchronizing rod, which in turn causes multiple first handles to rotate synchronously, so that multiple quick-release components can be fixed or disengaged at the same time, thereby greatly improving the efficiency of nozzle disassembly and installation.

[0017] Preferably, an eccentric turntable is rotatably disposed on the side of the cover plate near the fixing part of the synchronizing rod, and a second handle is disposed on the eccentric turntable. When the locking part is fixedly connected to the fixing part, the synchronizing rod abuts against the side wall of the eccentric turntable near its own rotating shaft.

[0018] By adopting the above technical solution, when the fixed part and the snap-fit ​​part are released, the second handle is turned, the second handle drives the eccentric turntable to rotate, the eccentric turntable then pushes the synchronizing rod to move, and the synchronizing rod drives the snap-fit ​​part to rotate synchronously through multiple first handles, thereby facilitating the simultaneous release of multiple fixed parts and snap-fit ​​parts.

[0019] Preferably, a baffle plate is provided inside the tower body on the side of the packing layer near the gas outlet pipe.

[0020] By adopting the above technical solution, the waste gas purified by the packing layer is discharged from the tower body through the baffle plate. The baffle plate removes water and mist from the waste gas, thereby reducing the moisture content in the waste gas.

[0021] Preferably, a demisting layer is provided on the side of the baffle plate away from the packing layer.

[0022] By adopting the above technical solution, the exhaust gas after water and mist removal by the baffle plate is discharged from the tower body through the demister layer, and the demister layer further removes mist from the exhaust gas, thereby further reducing the moisture content in the exhaust gas.

[0023] Preferably, a ladder is provided on the outer wall of the tower.

[0024] By adopting the above technical solution, the ladder makes it easier for workers to climb the tower, thus facilitating the replacement of the nozzles.

[0025] Preferably, the outer wall of the tower body is provided with multiple observation windows.

[0026] By adopting the above technical solution, the observation window makes it easier for staff to observe the internal conditions of the tower.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By employing a detachable supply branch pipe, when a nozzle malfunctions and requires repair or replacement, the shut-off valve is closed to stop the supply to the faulty branch pipe. The branch pipe is then detached from the main supply pipe using a quick-release connector, allowing the nozzle to be removed from the tower body. After repair or replacement, the branch pipe is reinstalled on the main supply pipe, and the shut-off valve is opened. This significantly reduces the difficulty and speed of nozzle repair and replacement, as the shut-off valve stops the supply to the faulty branch pipe, eliminating the need to shut down the scrubbing unit during nozzle repair or replacement, thus improving the efficiency of waste gas purification.

[0029] By using quick-release components, rotating the arc-shaped ramp of the locking part and the slot to form a locking or unlocking connection can fix or release the locking part and the fixing part, thus facilitating quick assembly and disassembly of the nozzle.

[0030] By using a synchronizing rod, when fixing or loosening the fixing part and the snap-fit ​​part, rotating one of the first handles moves the synchronizing rod, which in turn drives multiple first handles to rotate synchronously, allowing multiple quick-release components to be fixed or loosened simultaneously, thereby greatly improving the efficiency of nozzle disassembly and installation.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a horizontal high-efficiency spray system for acid and alkali waste gas and water. Example 1

[0040] Reference Figure 1 and 2 A horizontal high-efficiency acid and alkali waste gas spraying system includes a horizontally placed tower body 1. An inlet pipe 2 and an outlet pipe 3, communicating with the inner cavity of the tower body 1, are fixedly installed at both ends of the tower body 1 in the horizontal direction. A packing layer 4, a baffle plate 15, and a demister layer 16 are sequentially installed in the inner cavity of the tower body 1 along the direction from the inlet pipe 2 to the outlet pipe 3. Perforated baffles 21 are fixedly installed on both sides of the tower body 1 at the packing layer 4, baffle plate 15, and demister layer 16. In this application, the packing layer 4 can be formed by filling with Raschig rings, hollow spheres, etc., and the demister layer 16 can be formed by filling with cyclone plates, mesh, ceramic balls, etc. A spraying mechanism 5 is installed on the tower body 1, which sprays the chemical solution into the packing layer 4.

[0041] The exhaust gas enters the inner cavity of the tower body 1 through the inlet pipe 2. The exhaust gas first enters the packing layer 4, where it undergoes acid-base neutralization with the chemical solution, thus purifying the exhaust gas. The purified exhaust gas then enters the baffle plate 15, where it removes water and demisters, reducing the moisture content. After removing water, the exhaust gas enters the demister layer 16, where it demisters again, further reducing the moisture content. Finally, the purified, dehydrated, and demistered exhaust gas is discharged from the tower body 1 through the outlet pipe 3.

[0042] Reference Figure 1 , 2Specifically, the spraying mechanism 5 includes a pressure supply component 51, a main liquid supply pipe 52, a branch liquid supply pipe 53, and nozzles 54. Two pressure supply components 51 are installed, fixedly mounted on the bottom of the outer wall of the tower body 1. The main liquid supply pipe 52 is fixedly mounted on the outer side of the tower body 1, and its inlet end is connected to the output ends of the two pressure supply components 51. In this application, the pressure supply component 51 can be a water pump, and the two pressure supply components 51 deliver the liquid to the main liquid supply pipe 52.

[0043] The main liquid supply pipe 52 has four outlets at the end furthest from the pressure supply component 51. A shut-off valve 6 is fixedly installed at each of the four outlets. A connecting pipe 22 is installed at the end of the shut-off valve 6 furthest from the main liquid supply pipe 52, and a pressure gauge 19 is installed on the connecting pipe 22. A quick-release connector 7 is installed at the end of the connecting pipe 22 furthest from the shut-off valve 6. Four supply branch pipes 53 are installed along the length of the tower body 1, and each supply branch pipe 53 is installed along the width of the tower body 1. The four supply branch pipes 53 are located above the tower body 1 and connected to the quick-release connector 7. Multiple nozzles 54 are installed at the bottom of the supply branch pipes 53 and directly above the packing layer 4 inside the tower body 1.

[0044] In this application, the quick-release connector 7 can be a union connector. Both ends of the quick-release connector 7 are inserted into or threaded into the connecting pipe 22 and the supply branch pipe 53, allowing the supply branch pipe 53 to be quickly detached from the connecting pipe 22. The liquid medicine in the main supply pipe 52 is delivered to the four supply branch pipes 53 via the shut-off valve 6 and the connecting pipe 22, and then sprayed into the filling layer through the nozzles 54. The pressure in the supply branch pipes 53 can be detected using the pressure gauge 19, thus facilitating the detection of whether the nozzles 54 are malfunctioning.

[0045] Four bases 8 are fixedly installed at equal intervals along the length of the tower body 1. Each base 8 is installed along the width of the tower body 1. The top of each base 8 is open, and a cover plate 10 is detachably and sealed at the top opening end of the base 8 through multiple quick-release components 9. Six liquid outlets are formed at equal intervals at the bottom end of each liquid supply branch pipe 53. The six liquid outlets are sealed through the cover plate 10, and nozzles 54 are installed on the liquid outlets of the liquid supply branch pipe 53.

[0046] When nozzle 54 malfunctions and requires repair or replacement, first close the shut-off valve 6 to stop the liquid supply to the faulty supply branch pipe 53. Then, use the quick-release connector 7 to remove the supply branch pipe 53 from the main supply pipe 52. Next, use the quick-release assembly 9 to remove the cover plate 10 from the seat 8. This allows the nozzle 54 to be removed from the tower body 1. After repair or replacement, reinstall the supply branch pipe 53 onto the main supply pipe 52, seal the cover plate 10 onto the seat 8, and then open the shut-off valve 6. This allows for easy removal of the nozzle 54 from the tower body 1 during repair or replacement, significantly reducing the difficulty and speed of nozzle repair or replacement. Furthermore, using the shut-off valve 6 to stop the liquid supply to the faulty supply branch pipe 53 eliminates the need to shut down the scrubbing unit during nozzle repair or replacement, thereby improving the efficiency of waste gas purification.

[0047] Reference Figure 3 Each cover plate 10 is equipped with fourteen quick-release components 9, with seven quick-release components 9 forming a row. The two rows of quick-release components 9 are located on both sides of the width direction of the liquid supply branch pipe 53. Each row of quick-release components 9 is arranged at equal intervals along the length direction of the liquid supply branch pipe 53, and two adjacent quick-release components 9 in each row are located on both sides of one output end of the liquid supply branch pipe 53.

[0048] Reference Figure 3 and 4 Specifically, the quick-release assembly 9 includes a fixing part 91 and a snap-fit ​​part 92. The fixing part 91 is composed of three stacked plates, and two bolts pass through the three plates to fix the fixing part 91 to the top of the base body 8. An arc-shaped slot 911 is provided in the middle of the side wall of the middle plate of the fixing part 91 near the liquid supply branch pipe 53.

[0049] The snap-fit ​​part 92 is rotatably mounted on the cover plate 10. A first handle 11 is fixedly mounted on the top of the snap-fit ​​part 92, which can drive the snap-fit ​​part 92 to rotate on the cover plate 10. An arc-shaped ramp 921 is integrally formed on the outer wall of the snap-fit ​​part 92. The arc-shaped ramp 921 is rotatably mounted in the arc-shaped slot 911, and the height of the arc-shaped ramp 921 gradually increases from low to high.

[0050] When the engaging part 92 rotates, causing the high end of the arc-shaped ramp 921 to rotate into the slot 911, the arc-shaped ramp 921 and the slot 911 form a locking connection, thereby fixing the cover plate 10 to the base 8. A flat wall 922 is formed at the bottom end of the arc-shaped ramp 921 in the engaging part 92. When the engaging part 92 rotates, causing the bottom end of the arc-shaped ramp 921 to rotate into the slot 911, the arc-shaped ramp 921 and the slot 911 are released from the locking connection, thereby releasing the cover plate 10 from the base 8. When the engaging part 92 rotates, causing the flat wall 922 to move parallel to the fixing part 91 and approach the side wall of the engaging part 92, the flat wall 922 provides clearance, allowing the engaging part 92 to be removed from the fixing part 91, and the cover plate 10 to be detached from the base 8. The cover plate 10 can be fixed and unfixed by rotating the snap-fit ​​part 92, which facilitates quick assembly and disassembly of the nozzle 54 and further reduces the maintenance difficulty of the nozzle 54.

[0051] Reference Figure 1 and 2 The top of the tower body 1 is equipped with a plate 23 directly above the baffle plate 15 and the demister layer 16. Multiple quick-release components 9 are installed on the plate 23. The plate 23 can be detachably and fixedly installed on the tower body 1 through the quick-release components 9, which facilitates the disassembly of the plate 23 and the inspection and maintenance of the baffle plate 15 and the demister layer 16.

[0052] The liquid medicine in the inner cavity of tower body 1 drips to the bottom of the tower body. The pressure supply component 51 draws the liquid medicine at the bottom of tower body 1 and supplies it back into the liquid supply main pipe 52. The liquid supply main pipe 52 is equipped with a pH meter and a conductivity meter, which detect the circulating liquid medicine, thus facilitating the monitoring of the liquid medicine's state. At the same time, a level gauge is installed at the bottom of tower body 1 to detect the amount of liquid medicine at the bottom of tower body 1, thus facilitating the rapid detection of the remaining liquid medicine by the staff.

[0053] Reference Figure 1 and 5 A ladder 17 is vertically fixedly installed on the side wall of the tower body 1 away from the pressure supply component 51. The ladder 17 facilitates workers to climb the tower body 1, thereby facilitating the replacement of the nozzle 54. Multiple observation windows are detachably and fixedly installed on the outer periphery of the tower body 1 via quick-release components 9. The observation windows facilitate workers to observe the internal conditions of the tower body 1, and the quick-release components 9 make it easy to remove the observation windows from the tower body 1.

[0054] The implementation principle of Embodiment 1 of this application is as follows: the waste gas enters the inner cavity of the tower body 1 from the inlet pipe 2. The waste gas first enters the packing layer 4, where it undergoes a purification reaction with the liquid in the packing layer 4. The purified waste gas then enters the baffle plate 15, where it removes water and demisters, thereby reducing the moisture content of the waste gas. The waste gas after water removal then enters the demister layer 16, where it demisters again, further reducing the moisture content of the waste gas. Finally, the purified, dehydrated, and demistered waste gas is discharged from the tower body 1 through the outlet pipe 3.

[0055] When nozzle 54 malfunctions and requires repair or replacement, first close the shut-off valve 6 to stop the liquid supply to the faulty supply branch pipe 53. Then, use the quick-release connector 7 to remove the supply branch pipe 53 from the main supply pipe 52. Next, use the quick-release assembly 9 to remove the cover plate 10 from the seat 8. This allows the nozzle 54 to be removed from the tower body 1. After repair or replacement, reinstall the supply branch pipe 53 onto the main supply pipe 52, seal the cover plate 10 onto the seat 8, and then open the shut-off valve 6. This allows for easy removal of the nozzle 54 from the tower body 1 during repair or replacement, significantly reducing the difficulty and speed of nozzle repair or replacement. Furthermore, using the shut-off valve 6 to stop the liquid supply to the faulty supply branch pipe 53 eliminates the need to shut down the scrubbing unit during nozzle repair or replacement, thereby improving the efficiency of waste gas purification. Example 2

[0056] Reference Figure 6 The difference between this embodiment and Embodiment 1 is that a synchronizing rod 12 is installed on both rows of quick-release components 9 of the cover plate 10. The synchronizing rod 12 is installed along the length of the liquid supply branch pipe 53, and each synchronizing rod 12 is rotatably connected to the end of the top wall of the seven first handles 11 in each row of quick-release components 9 near the liquid supply branch pipe 53. When fixing or loosening the fixing part 91 and the snap-fit ​​part 92, rotating one first handle 11 moves the synchronizing rod 12, and the synchronizing rod 12 drives multiple first handles 11 to rotate synchronously, so that the seven quick-release components 9 can be fixed or loosened at the same time, thereby greatly improving the efficiency of nozzle 54 disassembly and installation.

[0057] The cover plate 10 has eccentric turntables 13 mounted on both sides of the third quick-release assembly 9 in each row via a rotating shaft. The eccentric turntables 13 are located on the side of the synchronizing rod 12 away from the liquid supply branch pipe 53, and a second handle 14 is fixedly mounted on the side of the eccentric turntables 13 away from the synchronizing rod 12. The operator can drive the eccentric turntables 13 to rotate on the cover plate 10 through the second handle 14. When the quick-release assembly 9 is in the locked state, the rotating part drives the synchronizing rod 12 to move and abut against the eccentric turntables 13 through the first handle 11. At this time, the synchronizing rod 12 abuts against the side wall of the eccentric turntables 13 located near its own rotating shaft.

[0058] When an operator rotates a first handle 11, the first handle 11 moves the synchronizing rod 12, which in turn moves multiple first handles 11 synchronously. Because multiple moving parts are simultaneously engaged and fixed within multiple fixed parts 91, the operator needs to exert considerable force to move the synchronizing rod 12 using only one handle, which makes the use of the synchronizing rod 12 inconvenient.

[0059] At this time, the operator simultaneously rotates the two second handles 14 on one side of the fluid supply branch pipe 53. The two second handles 14 drive the two eccentric turntables 13 to rotate. During the rotation of the eccentric turntables 13, the distance between the side wall of the eccentric turntable 13 and the synchronous rod 12 and its own axis of rotation gradually increases. Therefore, the two eccentric turntables 13 continuously push the synchronous rod 12 to move closer to the fluid supply branch pipe 53. The synchronous rod 12 then drives the locking part 92 to rotate through multiple first handles 11, thereby releasing the quick-release assembly 9 from its locked state. In this way, the operator can drive the synchronous rod 12 to move with relatively little force, thus facilitating the simultaneous unlocking of multiple quick-release assemblies 9.

[0060] The implementation principle of Embodiment 2 of this application is as follows: the operator rotates the second handle 14, the second handle 14 drives the synchronizing rod 12 to move through the eccentric turntable 13, and the synchronizing rod 12 drives the locking part 92 to rotate through the first handle 11, thereby facilitating the simultaneous unlocking of multiple quick-release components 9, and thus greatly improving the disassembly efficiency of the nozzle 54.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
