DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0026] The following describes, with reference to the accompanying drawings, an environmentally friendly treatment system for smoke and waste gas emissions based on strong acidity according to an embodiment of the present application.

[0027] When the spray tower is treating acidic mist, the generated salt crystals and dust in the gas will gradually clog the surface of the hollow balls in the packing layer. The salt crystals attached to the surface of the hollow balls gradually accumulate, which makes the space for gas and liquid circulation in the packing layer smaller and smaller, and eventually leads to the gradual deterioration of the acid waste gas treatment effect. The existing technology mainly uses the shutdown method to clean the salt crystals blocked in the packing layer, which leads to high costs. If the salt crystals in the packing layer can be treated without affecting the spray tower's treatment of acidic mist, the cleaning cost can be greatly reduced.

[0028] See also Figure 1-Figure 6According to an embodiment of the present application, an environmental protection treatment system for smoke exhaust gas emission based on strong acidity includes: a spray tower body 1 and a filler storage cleaning mechanism 2. The filler storage cleaning mechanism 2 is installed inside the spray tower body 1. The filler storage cleaning mechanism 2 includes an ultrasonic storage cleaning component 21, a mechanical reciprocating vibration mechanism 22 and an outer cylinder shell 23. The outer cylinder shell 23 is embedded in the spray tower body 1, and multiple groups of ultrasonic storage cleaning components 21 are installed inside the outer cylinder shell 23. The ultrasonic storage cleaning component 21 includes a storage bin 211, a filter plate 212 and an ultrasonic transducer 216, and a connected air duct 214 is provided at the bottom of the storage bin 211. A valve 215 is installed at the air duct 214, and the valve 215 can be a butterfly valve, and the valve body has a relatively larger flow area inside. The filter plate 212 is located inside the filter plate 212 and connected by an elastic connection part 213, and the filler layer is laid inside the storage bin 211 above the filter plate 212. The ultrasonic transducer 216 is installed on the inner wall of the storage bin 211 below the filter plate 212, and the mechanical reciprocating vibration mechanism 22 is installed inside the spray tower body 1 to drive the filter plate 212 to reciprocate in the vertical direction.

[0029] In this embodiment, the filler storage and cleaning mechanism 2 is not only used to store the hollow ball filler, but also can clean the hollow ball filler while the spray tower is running. The spray tower equipment does not need to be shut down for cleaning, which greatly reduces the cleaning cost. During normal operation, the valves 215 outside the multiple groups of air ducts 214 are all in an open state, and the acidic smoke enters the storage bin 211 from top to top through the air duct 214. In this embodiment, the filter plate 212 adopts a filter plate. After the acidic smoke enters the storage bin 211 through the air duct 214, it contacts the alkaline water mist on the surface of the hollow ball filler stored in the storage bin 211 through the filter plate 212. That is, the sprayed alkaline mist water is sprayed in the filler layer inside the storage bin 211, so that the surface of the hollow ball in the filler layer is covered with alkaline liquid, increasing the contact area with the acidic mist, and realizing the neutralization treatment of the acid mist. The neutralized sewage will also be discharged into the bottom of the spray tower body 1 along the storage bin 211 and the air duct 214.

[0030] The specific cleaning method of the environmental protection treatment system for the emission of highly acidic smoke waste gas is as follows: close the valve 215 outside part of the air duct 214, and the acidic waste gas can enter the packing layer through the other part of the air duct 214 for neutralization treatment. The air duct 214 with the valve 215 closed can store fog water in the storage bin 211 above, and a corresponding water supply pipe can be set on the spray tower body 1 to add clean water or cleaning solution. Start the ultrasonic transducer 216 to vibrate the salt crystals attached to the surface of the filter plate 212 and the surface of the hollow balls in the packing layer through the liquid, and the lightly attached saline-alkali particles can directly fall into the bottom side of the storage bin 211. Frequent vibration makes the saline-alkali crystal liquid loose, and then cooperate with the mechanical reciprocating vibration mechanism 22 to vibrate the filter plate 212, that is, it also drives the hollow balls in the packing layer above the filter plate 212 to vibrate, and the saline-alkali liquid crystals dispersed by the ultrasonic wave will fall into the storage bin 211 in large quantities after the vibration of the mechanical reciprocating vibration mechanism 22. Open the valve 215 again, and the sewage and saline-alkali residue inside the storage bin 211 fall into the bottom of the spray tower body 1. Then close the valve 215 outside the air guide pipe 214 in the other ultrasonic storage cleaning component 21 that has not been cleaned, and clean the saline-alkali crystals in the packing layer in the above manner. The environmental protection treatment system for smoke exhaust gas emission based on strong acidity can realize the cleaning of the packing stored in the ultrasonic storage cleaning component 21 in batches, and can clean the packing layer without stopping the machine, which greatly reduces the cleaning and maintenance costs.

[0031] In the above specific implementation, please refer to Figure 3 The mechanical reciprocating vibration mechanism 22 includes a motor 221, a reciprocating suspension assembly 222 and an impact block 223. The mechanical reciprocating vibration mechanism 22 is arranged inside the spray tower body 1, and the motor 221 is installed outside the spray tower body 1 to drive the reciprocating suspension assembly 222 to drive the impact block 223 to reciprocately impact the filter plate 212. That is, the motor 221 drives the impact block 223 to reciprocately impact the filter plate 212 through the reciprocating suspension assembly 222, so as to clean the loosened salt-alkali crystals in the packing layer and the filter plate 212.

[0032] For details, please refer to Figure 5 The reciprocating suspension assembly 222 includes a hanger 2221, an eccentric shaft 2222, a connecting block 2223, a bracket 2224 and a rope 2226. The motor 221 is fixed inside the spray tower body 1, one end of the eccentric shaft 2222 is connected to the output shaft end of the motor 221, and the other end of the eccentric shaft 2222 is connected to the hanger 2221 through the bracket 2224. A pulley 2225 is installed below the hanger 2221, and a rope threading hole 218 is provided on the filter plate 212. One end of the rope 2226 is connected to the connecting block 2223, and the connecting block 2223 is rotatably arranged with the eccentric shaft 2222. The other end of the rope 2226 passes through the pulley 2225 and the rope threading hole 218 and is connected to the impact block 223.

[0033] The motor 221 drives the eccentric shaft 2222 in the reciprocating suspension assembly 222 to rotate, and the rotating eccentric shaft 2222 drives the connecting block 2223 to pull the rope 2226 to reciprocate, that is, drives the impact block 223 at the bottom of the rope 2226 to reciprocate in the vertical direction to impact the bottom of the filter plate 212. When the impact block 223 collides with the bottom of the filter plate 212, the elastic connection part 213 plays a good buffering and protective role. The motor 221 and the reciprocating suspension assembly 222 can also be set in multiple groups. When cleaning the packing layer on the filter plate 212 inside the corresponding motor 221, it is only necessary for the corresponding motor 221 to drive the filter plate 212 in the corresponding storage bin 211 to vibrate, which has better pertinence when cleaning.

[0034] For further information, see Figure 4 and Figure 5 The bracket 2224 is provided with a bearing, and the end of the eccentric shaft 2222 is inserted into the inner ring of the bearing for installation. The bearing is provided to ensure the smooth rotation of the eccentric shaft 2222. The elastic connection part 213 includes a buffer 2131 and a connection seat 2132. The connection seat 2132 is fixed to the inner wall of the storage bin 211, and the two ends of the buffer 2131 are respectively connected to the connection seat 2132 and the filter plate 212. The buffer 2131 in the elastic connection part 213 provides a good buffering effect for the filter plate 212, that is, it has a good protective effect on the filter plate 212.

[0035] Specifically, the ultrasonic storage cleaning assembly 21 further includes a bracket 217, which is located below the filter plate 212 and fixed to the filter plate 212. The bracket 217 can be used to support the filter plate 212 placed stably above.

[0036] In the specific configuration, the bottom of the storage bin 211 is a conical structure that is easy to guide, which is conducive to the sewage, stains and debris flowing along the inner wall of the storage bin 211 and being discharged from the air duct 214. Multiple groups of ultrasonic transducers 216 are arranged on the inner wall of the conical structure of the storage bin 211 in a ring array.

[0037] See also Figure 1 and Figure 2 The highly acidic smoke exhaust gas emission environmental treatment system further includes a water tank 3, which is installed at the bottom of the spray tower body 1, and at least a clean water storage chamber and a sewage storage chamber are provided inside the water tank 3. The sewage storage tank in the water tank 3 is used to store the sewage and impurities removed by spraying in the spray tower body 1, and the clean water storage chamber is used to provide clean water to the spray tower body 1 when spraying.

[0038] Specifically, the spray tower body 1 also includes an air inlet 11 on the side of the bottom section and an air outlet 12 on the side of the fixed section, and an inspection port 15 is provided on the side of the spray tower body 1. The spray tower body 1 also includes a spray layer 13 and a demister 14. The spray layer 13 is located above the filler storage and cleaning mechanism 2, and the demister 14 is located above the spray layer 13. The spray layer 13 and the demister 14 are both installed inside the spray tower body 1. The spray layer 13 is used for atomization spraying, and the demister 14 is used to remove the mist water in the flue gas.

[0039] The storage bin 211 in the ultrasonic storage and cleaning assembly 21 stores the hollow ball packing layer, and the salt and alkali crystals attached to the surface of the hollow balls can be cleaned by vibration through the impact block 223 impacting the bottom of the filter plate 212. However, the hollow balls in the middle of the packing layer are difficult to be efficiently cleaned by ultrasonic vibration, resulting in a relatively poor cleaning effect when the impact block 223 impacts the filter plate 212 to drive the vibration of this part of the hollow balls.

[0040] See also Figure 7 , Figure 8 and Fig. 9 The environmental protection treatment system for smoke exhaust gas emission based on strong acidity also includes a guide hole cleaning mechanism 4, which includes a lower support arm 41, an upper support arm 42, a protrusion 44, and a fixed sleeve 45. One end of multiple groups of lower support arms 41 is fixedly connected to the impact block 223, and the fixed sleeve 45 is fixedly sleeved on the outside of the rope 2226 located above the filter plate 212. One end of the upper support arm 42 is fixedly connected to the outer wall of the fixed sleeve 45, and a plurality of wire ropes 43 are equidistantly arranged between the lower support arm 41 and the upper support arm 42. Multiple groups of guide holes 2121 are arranged on the filter plate 212, and the protrusion 44 is fixedly sleeved on the outside of the wire rope 43. The wire rope 43 and the protrusion 44 are both movable through the guide hole 2121.

[0041] In this embodiment, the filter plate 212 adopts a supporting plate with a plurality of guide holes 2121 disposed on the top, and a rope threading hole 218 matched with the rope 2226 is also disposed in the middle. In the process of cleaning the packing layer, when the rope 2226 drives the impact block 223 at the bottom to reciprocate and impact the filter plate 212, the hollow balls in the packing layer above the filter plate 212 vibrate in the vertical direction. And when the rope 2226 reciprocates in the vertical direction, it also synchronously drives the lower support arm 41 and the upper support arm 42 in the guide hole cleaning mechanism 4 to reciprocate in the vertical direction. The reciprocating upper support arm 42 can flip the hollow balls in the packing layer, that is, the same driving mechanism drives the impact block 223 to impact the filter plate 212 to drive the upper hollow balls to vibrate in the vertical direction, and the hollow balls near the middle area of ​​the packing layer are also flipped. The flipping hollow balls are impacted, causing the salt-alkali crystals on the surface to fall off, and changing the contact area between this part of the hollow balls and the cleaning water stains. Ultrasonic waves can more easily peel off the salt-alkali crystals on the surface of this part of the hollow balls through the cleaning water stains, further improving the cleaning effect of the filler layer.

[0042] When the lower support arm 41 and the upper support arm 42 are moving back and forth in the vertical direction, the rope 43 between the lower support arm 41 and the upper support arm 42 will also drive the protrusion 44 thereon to move back and forth in the vertical direction. The protrusion 44 passes through the guide hole 2121 on the filter plate 212, which can effectively prevent larger salt-alkali crystals from clogging the guide hole 2121 during cleaning, thereby ensuring that the filter plate 212 has a good guide effect during cleaning.

[0043] How to design the upper support arm 42 and the protrusion 44 to achieve a better cleaning effect when in use will be further described in the following embodiments.

[0044] For specific settings, see Fig. 9 and Fig.10 The guide hole cleaning mechanism 4 also includes a prism shell 46, which is solidly sleeved outside the upper support arm 42, and the two sets of ridges of the prism shell 46 are respectively facing upward and downward. The top of the rope 43 passes through the bottom shell wall of the prism shell 46 and is connected to the upper support arm 42. The top outer edge and the bottom outer edge of the protrusion 44 are both set as a bevel chamfer 441 structure, and the middle outer wall of the protrusion 44 is provided with a groove 442.

[0045] When the upper support arm 42 moves back and forth in the vertical direction, it will also drive the outer prismatic shell 46 to move. The upper and lower parts of the prismatic shell 46 are both pointed structures. When the prismatic shell 46 moves in the vertical direction, it has a larger contact area with the hollow balls inside the packing layer. It is also easier to separate the hollow spherical shells close to the prismatic shell 46 when moving up and down. When moving, the contact area with the spherical shell is increased, and the resistance during impact is reduced, thereby reducing the load of the motor 221.

[0046] When the protrusion 44 reciprocates through the guide hole 2121 on the filter plate 212, the chamfers 441 on the top and bottom of the protrusion 44 play a guiding role, so that the protrusion 44 can pass through the guide hole 2121 more smoothly and stably. The groove 442 in the middle of the outer part of the protrusion 44 is also designed to better break the salt-alkali blocks attached to or remaining at the guide hole 2121 when the protrusion 44 passes through the guide hole 2121, and at the same time hit the bottom of the filter plate 212 through the air guide pipe 214 and fall to the bottom of the spray tower body 1, so as to further improve the overall treatment effect of the treatment system on the salt-alkali crystals in the packing layer.

[0047] It should be noted that the specific model specifications of the motor 221 and the ultrasonic transducer 216 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply and principle of the motor 221 and the ultrasonic transducer 216 are clear to those skilled in the art and will not be described in detail here.
