Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a detachable packing fixing grid for a spray tower. Background Technology

[0002] Spray towers are widely used gas-liquid mass transfer devices in industrial waste gas treatment. They achieve the absorption or neutralization of harmful components through sufficient contact between the sprayed liquid and the rising waste gas. Depending on the treatment medium and operating conditions, spray towers can be made of materials such as fiberglass, PP, or stainless steel, and are equipped with appropriate packing layers to enhance gas-liquid contact efficiency. The packing layer typically consists of loose or structured packing, which must be placed on a fixed grid frame inside the tower to maintain its stable position within the tower and ensure uniform airflow distribution, thereby guaranteeing the treatment effect.

[0003] Currently, the packing fixing frame in spray towers is mostly permanently fixed to the inner wall of the tower body by welding or bolts. This means that when the packing is replaced, cleaned, or repaired, the machine must be shut down and some or even the entire tower structure must be disassembled. This process is not only cumbersome and time-consuming, but also significantly affects the continuous operation capability of the waste gas treatment system and reduces the overall treatment efficiency. In addition, frequent disassembly and assembly can easily cause damage to the tower structure and increase maintenance costs. Therefore, we propose a detachable packing fixing frame for spray towers to meet the actual needs of efficient operation and maintenance and rapid maintenance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem of this utility model is to provide a detachable packing fixing grid for a spray tower.

[0005] A detachable packing mesh frame for a spray tower includes a spray tower body, which serves as the mounting carrier for the packing mesh frame. The spray tower body has a square chamber for installing the packing mesh frame, and one side of the spray tower body has an opening for inserting the packing mesh frame. The packing mesh frame is composed of an arc-shaped plate and a packing mesh frame. The packing mesh frame is slidably installed within the square chamber of the spray tower body. The packing mesh frame is square, and a filter screen is provided at the bottom of the packing mesh frame. An arc-shaped plate is fixedly installed on the outer wall of the packing mesh frame, tightly fitting the arc-shaped outer wall of the spray tower body. Locking elements are symmetrically arranged on both sides of the arc-shaped plate to stably lock the packing mesh frame within the square chamber of the spray tower body. Sliding grooves are symmetrically opened on the left and right sides of the inner wall of the square chamber of the spray tower body. A baffle is also slidably installed within the square chamber of the spray tower body, slidingly engaging with the sliding grooves. The baffle is located inside the packing mesh frame and is used to close the opening of the spray tower body.

[0006] To further explain, the locking component consists of an arc-shaped block, a plug rod, and a spring. Arc-shaped blocks are symmetrically fixedly connected to both sides of the arc-shaped plate, and a plug rod is slidably connected to the arc-shaped block. A ring is provided at the outer end of the plug rod for easy operation, and a spring is provided between the arc-shaped block and the plug rod.

[0007] To further explain, the outer wall of the spray tower body has a hole corresponding to the insertion rod, and the insertion rod is inserted into the insertion hole; when the insertion rod on the arc block is pulled outward, the spring extends, causing the insertion rod to disengage from the insertion hole, and the packing mesh frame that is no longer locked by the insertion rod can be quickly removed from the spray tower body.

[0008] To further explain, a strong magnet is fixedly installed on the inner wall of the packing mesh frame near the baffle, and the strong magnet is used to attract the baffle.

[0009] To further explain, an iron block is fixedly installed at the location of the strong magnet corresponding to the baffle, and the iron block is magnetically coupled with the strong magnet. When the packing mesh frame is pulled out from the square chamber of the spray tower, the iron block on the baffle will be attracted and moved by the strong magnet of the packing mesh frame until the packing mesh frame is completely detached from the spray tower. At this time, the baffle is limited by the sliding groove, and the strong magnet and iron block that are attracted together are pulled apart by external force, so that the baffle can automatically stop and block the opening. There is no need for manual pushing and pulling of the baffle, thus ensuring that the spray tower can still work normally during maintenance.

[0010] To further explain, hanging rings are fixedly installed at the four corners of the outer circumference of the arc-shaped plate. The hanging rings serve as the force points of the arc-shaped plate, facilitating the quick installation and removal of the packing mesh frame on the spray tower body.

[0011] The beneficial effects of this utility model are as follows: 1. By setting a slidable and detachable packing mesh frame and an automatic sealing baffle structure, when the packing mesh frame is disassembled for maintenance or packing replacement, the baffle can automatically seal the opening, effectively preventing flue gas leakage. Thus, maintenance work can be completed without stopping the machine, significantly improving the operating efficiency of the equipment.

[0012] 2. This utility model uses an arc-shaped plate and a filling mesh frame to form an overall mesh frame, and is guided and slidably installed by a sliding groove. With a hanging ring as the force point, it is easy to load and unload manually and quickly. The locking mechanism makes the unlocking and locking operation simple and reliable.

[0013] 3. This utility model utilizes the magnetic attraction between a strong magnet and an iron block to make the baffle automatically follow and move during the extraction of the packing mesh frame, and automatically position itself to seal the opening after the mesh frame is completely detached, without the need for additional operation, thus improving the degree of automation and reliability of use.

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0020] A detachable packing fixing grid for a spray tower, such as Figures 1-4 As shown, the system includes a spray tower body 1, which serves as the mounting carrier for the packing mesh frame. The spray tower body 1 has a square chamber inside for installing the packing mesh frame, and an opening on one side for inserting the packing mesh frame. The packing mesh frame is composed of an arc-shaped plate 2 and a packing mesh frame 3. The packing mesh frame 3 is slidably installed within the square chamber of the spray tower body 1. The packing mesh frame 3 is a square frame, with a filter screen at its bottom. The arc-shaped plate 2 is fixedly mounted on the outer wall of the packing mesh frame 3, tightly fitting the arc-shaped outer wall of the spray tower body 1. Locking elements are symmetrically arranged on both sides of the arc-shaped plate 2 to stably lock the packing mesh frame 3 within the square chamber of the spray tower body 1. The inner walls of the square chamber of the spray tower body 1 are located on the left and right sides... The spray tower body 1 has symmetrical sliding grooves 9 on both sides. A baffle 10 is also slidably installed in the square cavity of the spray tower body 1. The baffle 10 and the sliding groove 9 are slidably engaged. The baffle 10 is located inside the packing mesh frame 3 and is used to close the opening of the spray tower body 1. When it is necessary to disassemble the packing mesh frame 3, the arc plate 2 is unlocked by the locking device first. Then the packing mesh frame 3 is slid out of the square cavity of the spray tower body 1 and removed. After removing the packing mesh frame 3, the baffle 10 can be manually pulled outward so that the baffle 10 blocks the opening of the spray tower body 1. At this time, the flue gas in the spray tower body 1 cannot escape from the opening. This allows for convenient maintenance and replacement of the packing of the packing mesh frame 3 without stopping the operation of the spray tower body 1.

[0021] like Figure 1 and Figure 4As shown, the locking component consists of an arc-shaped block 5, a rod 6, and a spring 7. Arc-shaped blocks 5 are symmetrically fixedly connected to both sides of the arc-shaped plate 2. A rod 6 is slidably connected to the arc-shaped block 5. A ring is provided at the outer end of the rod 6 for easy operation. A spring 7 is provided between the arc-shaped block 5 and the rod 6.

[0022] like Figures 1-3 As shown, the outer wall of the spray tower body 1 has a hole 8 corresponding to the insertion rod 6. The insertion rod 6 is inserted into the hole 8. When the insertion rod 6 on the arc block 5 is pulled outward, the spring 7 extends, causing the insertion rod 6 to disengage from the hole 8. The packing mesh frame 3, which is no longer locked by the insertion rod 6, can be quickly removed from the spray tower body 1.

[0023] like Figure 2 As shown, a strong magnet 11 is fixedly installed on the inner wall of the packing mesh frame 3 near the baffle 10. The strong magnet 11 is used to attract and drive the baffle 10.

[0024] like Figure 2 and Figure 3 As shown, an iron block 12 is fixedly installed on the baffle 10 at the location corresponding to the strong magnet 11. The iron block 12 magnetically engages with the strong magnet 11. When the packing mesh frame 3 is pulled out from the square cavity of the spray tower body 1, the iron block 12 on the baffle 10 will be attracted and moved by the strong magnet 11 of the packing mesh frame 3 until the packing mesh frame 3 is completely detached from the spray tower body 1. At this time, the baffle 10 is limited by the sliding groove 9, and the strong magnet 11 and the iron block 12 attracted together are pulled apart by external force, so that the baffle 10 can automatically stop and block the opening. There is no need for manual pushing and pulling of the baffle 10, thus ensuring that the spray tower body 1 can still work normally during maintenance.

[0025] like Figure 2 As shown, hanging rings 4 are fixedly installed at the four corners of the outer circumference of the arc plate 2. The hanging rings 4 serve as the force points of the arc plate 2, making it convenient to quickly install and remove the packing mesh frame 3 on the spray tower body 1.

[0026] During normal operation of the spray tower, the packing mesh frame 3 is stably installed in the square cavity of the spray tower body 1 by locking parts on both sides. The filter screen at the bottom of the packing mesh frame 3 supports the packing, and the arc plate 2 fits tightly against the outer wall of the tower body to ensure a seal. When maintenance or replacement of the packing is required, the operator first grasps the ring on the insert rod 6 on both sides of the arc plate 2 and pushes it outward to make the insert rod 6 overcome the force of the spring 7 and disengage from the insertion hole 8 on the side wall of the spray tower body 1, thereby releasing the lock. Then, the packing mesh frame 3 is slowly pulled outward along the slide groove 9 by the hanging ring 4 on the arc plate 2. During the pulling process, due to the mutual attraction between the strong magnet 11 on the inner wall of the packing mesh frame 3 and the iron block 12 on the baffle 10, the baffle 10 will move outward with the packing mesh frame 3 and is always guided and constrained by the slide groove 9. When the packing mesh frame 3 is completely separated from the spray tower body 1, the baffle 10 is limited by the slide groove 9. The system automatically stops, precisely sealing the opening on the side of the spray tower body 1 to prevent flue gas from escaping. At this time, the strong magnet 11 and the iron block 12 separate under the pulling force, and the baffle 10 remains in its original position, allowing the spray tower body 1 to continue operating without stopping. After the maintenance or replacement of the packing is completed, the packing mesh frame 3 is aligned with the opening and the slide groove 9 and pushed in. As the packing mesh frame 3 moves inward, the strong magnet 11 on the inner wall of the packing mesh frame 3 attracts the iron block 12 on the baffle 10 again, and drives the baffle 10 to slide back to its original position inside the spray tower body 1. When the packing mesh frame 3 is fully pushed to the working position, the insertion rod 6 is released, and the spring 7 pushes the insertion rod 6 to automatically insert into the corresponding insertion hole 8 on the tower wall, relocking the packing mesh frame. The entire installation and disassembly process does not require additional operation of the baffle 10, achieving efficient, convenient and safe packing maintenance, and effectively ensuring the continuous and stable operation of the spray tower.

[0027] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
