[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a ash removal tail gas recovery washing tower structure. Figure 1The structure of the ash-forming tail gas recovery washing tower includes an ash-forming machine 1, an ash-forming exhaust pipe 2, a tail gas pipe 3, and a washing tower body 4. The tail gas outlet of the ash-forming machine 1 is connected to the lower end of the washing tower body 4 through the ash-forming exhaust pipe 2 and the tail gas pipe 3. Such a layout ensures that when the ash-forming machine 1 is working, the tail gas generated by it can be smoothly transported to the inside of the washing tower body 4 through the ash-forming exhaust pipe 2 and the tail gas pipe 3. The tail gas outlet of the ash-forming machine 1 is provided with an outer screen 11. When the ash-forming machine 1 is working, the ash-forming tail gas can smoothly pass through the ash-forming exhaust pipe 2 and the tail gas pipe 3 to enter the inside of the washing tower body 4 for dust removal and waste heat recovery. A spray mechanism 21 is provided inside the ash-forming exhaust pipe 2 and the tail gas pipe 3. The contact time and contact area between the spray water and the tail gas can be increased, thereby improving the dust removal and heat recovery efficiency.

[0035] The washing tower body 4 comprises a tower body 41 and a sealing head 43, on which a gas phase outlet 431 and a remote pressure gauge port 432 are formed. The remote pressure gauge port 432 is used to place a remote pressure gauge to facilitate the detection of the internal pressure of the tower body 41.

[0036] The tower body 41 is provided with a flushing water inlet 411, a reflux port 412, a gas phase inlet 413, an overflow port 414, a water outlet 415, and a sewage outlet 416 from top to bottom; an in-situ thermometer port 418 is also provided at the bottom of the tower body 41, and the tower body 41 is provided with multiple sieve plates 42 from top to bottom.

[0037] Reference Figure 2 In some embodiments of the present invention, the tower body 41 is cylindrical, and a square tube 44 is formed in a partial area of ​​the tower body. The square tube 44 smoothly transitions with the cylindrical part of the tower body 41, and a preliminary filter element 5 is arranged in the square tube 44, and the preliminary filter element 5 is located between the gas phase inlet 413 and the bottom sieve plate 42; one end of the square tube 44 is an open end, and an extension cover 45 is arranged at the open end, and the bottom of the extension cover 45 extends downward to one side of the tower body 41.

[0038] A horizontally extending first rotating shaft 51 is installed at one end of the square tube 44, and a second rotating shaft 52 is installed on the extension cover 45. The horizontal height of the second rotating shaft 52 is lower than the horizontal height of the first rotating shaft 51, and a motor for driving the second rotating shaft 52 to rotate is arranged on the extension cover 45; a filter screen 53 is sleeved on the first rotating shaft 51 and the second rotating shaft 52, and a supporting rotating shaft 54 ​​is arranged on the extension cover 45, and the supporting rotating shaft 54 ​​supports the bottom of the filter screen 53.

[0039] A accommodating area 451 is formed at the bottom of the extension cover shell 45, and the second rotating shaft 52 is located in the accommodating area 451; a water inlet pipe 452 is installed on the extension cover shell 45, and a spray head 453 is arranged inside the extension cover shell 45 for cleaning the filter screen 53 located inside the extension cover shell 45, and a discharge port 454 is arranged at the bottom of the extension cover shell 45.

[0040] A separator 55 is disposed between two opposite side walls of the square tube 44, and is located between the upper and lower filter screens 53 to separate the upper and lower filter screens 53. The filter screen 53 may be a grid structure with openings, or a filter element with openings may be directly used.

[0041] When in use, the gas to be treated is first introduced into the washing tower body 4 through the gas phase inlet 413. At this time, the gas will be initially filtered through the preliminary filter element 5 in the square tube 44 to remove some impurities. The gas that has been initially filtered continues to flow upward and is further washed and separated through multiple sieve plates 42. In this process, the flushing water inlet 411, the reflux port 412, the overflow port 414, the water outlet 415 and the sewage outlet 416 respectively play the role of flushing, reflux, overflow, water discharge and sewage discharge. When the filter screen 53 needs to be cleaned, the motor is started to drive the second rotating shaft 52 to rotate, so that the filter screen 53 rotates into the extension cover 45. At this time, the spray head 453 cleans the filter screen 53 located inside the extension cover 45 to remove pollutants on the filter screen 53. After the cleaning is completed, the motor is started again to rotate the filter screen 53 back to its original position and continue the filtering operation.

[0042] In terms of maintenance, the present application realizes the automatic cleaning function of the filter 53 by driving the second rotating shaft 52 to rotate by a motor. This design greatly reduces the frequency and cost of manual maintenance and improves the automation level and operational convenience of the entire system. The automatic cleaning mechanism enables the filter 53 to be cleaned without stopping the machine, thereby maintaining the stability of the filtration efficiency and reducing the potential risk of production interruption.

[0043] Furthermore, since one end of the filter screen 53 is located in the accommodation area 451 , the water output from the spray head 453 can be directly collected in the accommodation area 451 , thereby soaking and cleaning the filter screen 53 .

[0044] When the filter 53 needs to be cleaned, the motor starts to drive the second rotating shaft 52 to rotate, so that the filter 53 rotates, and the dirty part of the filter 53 moves into the extension cover 45. At this time, the spray head 453 is turned on, and the cleaning liquid is evenly sprayed on the filter 53, and a pool is formed in the receiving area 451, and the filter 53 is completely immersed in it. This immersion cleaning method can penetrate into every pore of the filter 53 and effectively dissolve and remove stubborn dirt and impurities attached to the filter 53.

[0045] It should also be pointed out that the surface of the filter 53 after soaking may carry a small amount of liquid. When the filter 53 moves to the inside of the square tube 44, when the gas passes through the filter 53, the water on the surface of the filter 53 evaporates and the temperature of the surface of the filter 53 is low, thereby reducing the replacement frequency of the filter 53.

[0046] Among them, the style of the sieve plate 42 can be Figure 3 In the style, when the sieve plate 42 is multiple, you can use Figure 3 Different styles of the middle sieve plate 42. When 5 sieve plates 42 are provided, the 1st, 3rd, and 5th sieve plates 42 from top to bottom are used Figure 3 In the structure (3a), the second and fourth sieve plates 42 are used Figure 3 The structure in (3b) .

[0047] A manhole 417 may be provided on the tower body 41 corresponding to the sieve plate 42 to facilitate observation of the sieve plate 42. A manhole 417 may also be provided on the square tube 44 to facilitate observation of the filter screen 53.

[0048] In some embodiments of the present invention, an upper plate 58 and a lower plate 59 are arranged between two opposite side walls of the open end of the square tube 44. The upper plate 58 and the lower plate 59 are spaced apart from the adjacent filter screen 53, and the partition 55 is used in conjunction with the upper plate 58 and the lower plate 59.

[0049] An upper plate 58 and a lower plate 59 are cleverly arranged between two opposite side walls of the square tube 44. This arrangement is spaced apart from the adjacent filter screen 53 in structure, ensuring that the partition 55 can be used in conjunction with the upper plate 58 and the lower plate 59. This design not only optimizes the gas flow path, but also enhances the internal structural stability of the entire scrubbing tower body 4.

[0050] Specifically, by arranging the upper plate 58 and the lower plate 59 in the square tube 44, the amount of gas entering the extension housing 45 from the square tube 44 inside the washing tower can be significantly reduced. This effect slows down the gas flow rate, helps to increase the contact time between the gas and the washing liquid, and thus improves the washing efficiency. At the same time, this design can also effectively position the upper and lower positions of the filter 53, ensuring that the filter 53 remains stable during operation and avoiding large-scale shaking caused by gas flow.

[0051] In addition, the arrangement of the upper plate 58 and the lower plate 59 also provides additional support for the filter 53, reducing the risk of deformation caused by clogging or pressure difference changes of the filter 53. The stability of this structure not only prolongs the service life of the filter 53, but also ensures a long-term filtering effect.

[0052] In some embodiments, the partition 55 is parallel to the first rotating shaft 51, and the partition 55 includes arc-shaped side panels 551 extending along its length and located on both sides, and the two arc-shaped side panels 551 are connected by a cross bar 554; two longitudinally arranged elastic inflatable members 555 are arranged between the two arc-shaped side panels 551, wherein the top of the elastic inflatable member 555 located at the top is provided with an arc-shaped top plate 552 used in conjunction with the upper plate 58, and the bottom of the elastic inflatable member 555 located at the bottom is provided with an arc-shaped bottom plate 553 used in conjunction with the lower plate 59; an air pump is installed on the outside of the extension cover 45, and the air pump is connected to the elastic inflatable member 555.

[0053] When the air pump is turned on, it delivers air to the two elastic inflatable members 555, which begin to deform as the air pressure increases. This deformation causes the arc-shaped top plate 552 to push upward, wherein the elastic inflatable member 555 at the top pushes the top filter screen 53 upward until it is in close contact with the upper plate 58; similarly, the elastic inflatable member 555 at the bottom pushes the bottom filter screen 53 downward until it is in contact with the lower plate 59.

[0054] By precisely adjusting the pressure of the air pump, the user can control the deformation degree of the elastic inflatable member 555, thereby fine-tuning the contact tightness between the filter screen 53 and the upper plate 58 and the lower plate 59. This results in a better sealing effect between the square tube 44 and the extension housing 45, significantly reducing the amount of gas inside the square tube 44 entering the extension housing 45, which is crucial for maintaining the pressure balance inside the system and improving the washing efficiency.

[0055] Furthermore, when the spray head 453 is in use, due to the high gas flow rate there, a large amount of gas inside the washing tower may flow into the extension cover 45. At this time, the air pump may be turned on to make the gas inside the extension cover 45 more stable.

[0056] In addition, when the system needs to clean the filter 53, the user can easily turn off the air pump. At this time, as the air pressure is released, the elastic inflatable member 555 will gradually return to its original state, relieving the squeezing force on the filter 53. This allows the top and bottom filter screens 53 to rotate freely into the extension housing 45, and then the cleaning operation can be carried out. Such a design not only simplifies the operation process, but also avoids damage to the filter screen 53 during the cleaning process.

[0057] In some embodiments of the present invention, the hollow parts of the two arc-shaped side plates 551 can also be filled with foaming materials to make the structure more stable. An air intake central tube 556 is arranged at the center of the partition 55, and the air pump is connected to the air intake central tube 556; a plurality of connecting tubes 557 are installed on the air intake central tube 556, and the connecting tubes 557 are connected to the upper and lower elastic inflatable members 555.

[0058] In the present application, the central part of the partition 55 is designed as an air intake central tube 556. This core component plays a dual role of distributing air pressure and supporting the structure. The air intake central tube 556 not only provides a stable central support, but also integrates multiple connecting tubes 557. The air intake central tube 556 and the connecting tubes 557 can be made of hard materials, such as plastic. The setting of these pipes can make the air pressure evenly and effectively transmitted to the inside of the elastic inflatable member 555.

[0059] When the air pump is started, the air it inhales is delivered through the air intake center tube 556, and then the air is guided into each connecting tube 557. These connecting tubes 557 are designed very accurately, and each is connected to the elastic inflatable members 555 on both sides of the partition 55, ensuring that the air inhaled from the air pump can reach the two elastic inflatable members 555 at the same time.

[0060] As air is input, the elastic inflatable member 555 begins to expand, and the elastic inflatable member 555 gradually pops out under the action of air pressure, thereby pushing the arc-shaped top plate 552 connected thereto to move upward. The elastic inflatable member 555 at the upper part pushes the top filter screen 53 upward to make it in close contact with the upper plate 58, while the elastic inflatable member 555 at the bottom pushes the bottom filter screen 53 downward until it forms an effective seal with the lower plate 59.

[0061] This design ensures that the pressure distribution inside the system is uniform and balanced, making the sealing effect between the square tube 44 and the extension housing 45 more excellent. This not only reduces the amount of gas inside the square tube 44 entering the extension housing 45, but also ensures the stability and sealing of the washing tower during operation, further improves the washing efficiency, and prolongs the service life of the system.

[0062] In some embodiments, both the arc-shaped top plate 552 and the arc-shaped bottom plate 553 are provided with auxiliary parts 57. Taking the auxiliary parts 57 provided on the arc-shaped top plate 552 as an example, the auxiliary parts 57 include a rubber sheet 571. The rubber sheet 571 extends along the length direction of the arc-shaped top plate 552. The rubber sheet 571 is upwardly curled at both ends along the width direction of the arc-shaped top plate 552.

[0063] The design of the curved top plate 552 further integrates the auxiliary part 57 to enhance the sealing effect and improve the adaptability of the system. The core of the auxiliary part 57 is a rubber sheet 571, which is selected because rubber has excellent elasticity and durability. The rubber sheet 571 extends along the length of the curved top plate 552, and its uniqueness lies in the design that the two ends of the rubber sheet 571 along the width direction of the curved top plate 552 are upwardly tilted.

[0064] When the air pump is started, the elastic inflatable member 555 receives air and expands, which pushes the arc-shaped top plate 552 upward. In this process, the rubber sheet 571 is deformed due to the upward thrust of the arc-shaped top plate 552. This deformation is not a simple linear displacement, but the two ends of the rubber sheet 571 extend obliquely, that is, in the width direction, the two ends of the rubber sheet 571 do not simply move upward, but roll outward, forming a shape similar to a fish tail.

[0065] This oblique extension design enables the rubber sheet 571 to contact both sides of the upper plate 58 more effectively, thereby forming a tighter seal between the arc-shaped top plate 552 and the upper plate 58. This not only reduces the path that the gas may pass through, but also enhances the stability of the entire system when facing pressure changes. In addition, the elastic properties of the rubber sheet 571 allow it to provide a certain buffering effect when subjected to different pressures, which helps to absorb the vibration that may be generated during operation, further protecting the long-term stable operation of the equipment.

[0066] Specifically, two connecting pieces 572 are disposed on the upper end surface of the rubber piece 571 . The two connecting pieces 572 are extended along the length direction of the arc-shaped top plate 552 . Rubber contact pieces 573 are installed on the top of the two connecting pieces 572 .

[0067] In order to further improve the sealing effect, two connecting pieces 572 are designed on the upper end surface of the rubber sheet 571, and the two connecting pieces 572 are extended along the length direction of the arc-shaped top plate 552. This configuration ensures the integrity of the connecting piece 572 and the rubber sheet 571, while providing sufficient space to accommodate additional sealing components. On the top of the two connecting pieces 572, a rubber contact piece 573 is installed. Due to its soft texture and good elasticity, it can improve the contact sealing with the upper plate 58.

[0068] With this solution, a certain gap is designed to exist between the rubber contact sheet 573 and the rubber sheet 571. The existence of this gap allows the rubber contact sheet 573 to have a certain deformation space when it is squeezed by the upper plate 58. When the upper plate 58 contacts the rubber contact sheet 573, the rubber contact sheet 573 will deform, and this deformation not only absorbs the pressure generated during the contact, but also increases the contact area between the rubber contact sheet 573 and the upper plate 58 as the rubber contact sheet 573 is compressed, thereby significantly improving the sealing effect on the upper plate 58.

[0069] In addition, the deformation of the rubber contact piece 573 can also compensate for any small gaps caused by tolerances in the production process or long-term operation, ensuring the long-term stability and reliability of the system. This design takes into account the actual application conditions of the equipment, allowing the sealing system to adapt to various working conditions and maintain good performance regardless of temperature fluctuations, pressure changes or long-term continuous operation.

[0070] In some embodiments, the two connecting pieces 572 are located on both sides of the midline of the arc-shaped top plate 552 along its length direction.

[0071] Placing the connecting pieces 572 on both sides of the center line helps ensure that the pressure can be evenly distributed over the entire contact surface when the arc-shaped top plate 552 is squeezed by the upper plate 58. This avoids local overpressure or underpressure on the sealing contact surface, thereby improving the overall sealing efficiency.

[0072] Since the connecting piece 572 is located on both sides of the center line, the rubber contact piece 573 will deform more evenly when squeezed. This even deformation helps to form a continuous and even sealing line, reducing the risk of leakage, especially during long working hours.

[0073] The symmetrical layout of the connecting pieces 572 increases the stability of the entire arc-shaped top plate 552 structure, preventing possible distortion or displacement under high pressure, which is essential for maintaining long-term stable sealing performance.

[0074] In some embodiments of the present invention, tops of the two connecting pieces 572 both extend toward a side close to each other.

[0075] When the tops of the two connecting pieces 572 are arranged to extend toward one side close to each other, this arrangement produces a significant positive effect in terms of sealing performance and structural stability. This inwardly extending design makes the deformation of the rubber contact piece 573 more concentrated in the central area when it contacts the upper plate 58, thereby forming a highly concentrated sealing point near the center line of the arc-shaped top plate 552. This enhanced sealing effect is particularly critical for preventing gas leakage, especially under high pressure difference conditions.

[0076] In addition, since the connecting pieces 572 extend inward, they can provide more direct support to the rubber contact piece 573 when subjected to pressure from the upper plate 58, thereby reducing unnecessary deformation of the rubber material due to uneven force. This direct support helps the rubber contact piece 573 maintain its shape, thereby maintaining stable sealing performance over a long period of time, and reducing the risk of sealing failure due to material fatigue.

[0077] At the same time, this design also optimizes the contact area between the rubber contact sheet 573 and the upper plate 58, making the contact pressure more uniform and reducing the possibility of accelerated wear due to local excessive pressure. Uniform contact pressure also helps to improve the durability of the entire component and extend its service life.

[0078] In some embodiments, an air pump may be provided on the extension housing 45 to control the air pressure inside the extension housing 45, and the air pump may be used according to actual usage. For example, when the partition 55 is separated from the upper plate 58 and the lower plate 59, a positive pressure is formed, which reduces the amount of gas from the washing tower entering the extension housing 45.

[0079] In some embodiments, a vertical rod 56 is disposed at the bottom of the arc-shaped top plate 552 , and the vertical rod 56 is inserted into the cross bar 554 ; a vertical rod 56 is also disposed at the top of the arc-shaped bottom plate 553 , and the vertical rod 56 is inserted into the cross bar 554 .

[0080] In this way, when the arc-shaped top plate 552 moves upward, it can be restricted by the vertical rod 56, so that the movement of the arc-shaped top plate 552 is more stable.

[0081] In some embodiments, a condensation recovery machine 6 is further provided. The condensation recovery machine 6 includes a recovery body 61. The recovery body 61 is connected to the gas phase outlet 431 of the tower body 41. One end of the recovery body 61 is provided with a gas outlet 611. A spiral pipeline 62 is provided inside the recovery body 61. Both ends of the spiral pipeline 62 extend out of the recovery body 61 and have a spiral inlet 621 and a spiral outlet 622. A condensed water outlet is provided at the bottom of the recovery body 61.
