Description

Technical Field

[0001] This utility model relates to the field of desulfurization and dust removal, specifically a multi-layer baffle desulfurization and dust removal device. Background Technology

[0002] Multi-layer baffle desulfurization and dust removal device is a highly efficient wet flue gas purification equipment. Its core is to set up multiple layers of baffles with special structure inside the tower, which forces the flue gas to tortuously pass through. When the flue gas comes into countercurrent contact with the absorbent liquid sprayed from top to bottom, the baffle breaks the liquid into fine droplets, liquid films and bubbles, which greatly increases the gas-liquid contact area. Acidic gases such as sulfur dioxide in the flue gas are absorbed by alkaline liquid, while dust particles are captured through inertial collision and droplet interception, thereby achieving simultaneous desulfurization and dust removal.

[0003] Chinese patent CN222518151U discloses a multi-stage baffle-type desulfurization and dust removal device, including a stand, a dust collector housing, an inlet pipe, an outlet pipe, a shower assembly, a blower assembly, a filter structure, and a fixing structure. The stand is fixed to the lower end of the dust collector housing. First, the gas is cleaned by the shower assembly to remove impurities. The blower assembly ensures smooth airflow inside the dust collector housing, allowing the treated gas to be discharged smoothly. The filter structure consists of multi-stage baffles, which can effectively filter out sulfides and dust in the gas. The fixing structure fixes the filter structure and facilitates later replacement.

[0004] During the desulfurization and dust removal process, foreign objects will continuously stick to the surface of the baffles in the multi-stage baffle desulfurization and dust removal equipment. As the usage time increases, the baffles will become clogged, so the baffles need to be disassembled regularly for cleaning and treatment. However, the baffles in the above-mentioned patent are difficult to disassemble, which is inconvenient for maintenance personnel. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-layer baffle desulfurization and dust removal device. Pulling the baffle allows it to extend from the movable slot position. The outer baffle is inserted into the outer mounting slot, and the inner baffle is inserted into the second inner mounting slot. This facilitates baffle installation while improving its stability. During the lateral movement of the baffle, the inner baffle can slide and be engaged in the first inner mounting slot. This allows the movable slot position to be completely filled while the baffle is exposed on the side of the outer frame. The entire structure facilitates maintenance by personnel and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer baffle desulfurization and dust removal device, comprising an outer frame, three baffles evenly distributed longitudinally in the middle of the outer frame, a movable groove provided at one end of each baffle, an outer baffle welded to one side of the movable groove, an inner baffle welded to the other end of each baffle, an outer mounting groove provided on one side of the movable groove, and the interior of the outer mounting groove connected to the outer slot of the outer baffle, so that when the baffle is installed inside the outer frame, the outer baffle can be locked in the outer mounting groove, providing a stable installation position.

[0007] Preferably, a second inner mounting groove is provided on one side of the outer side of the inner baffle, and the outer side of the inner baffle is connected to the inner slot of the second inner mounting groove. On the other hand, when the partition is installed inside the outer frame, the inner baffle can be locked in the position of the second inner mounting groove, further providing a stable installation position.

[0008] Preferably, the second inner mounting groove is recessed inside the outer frame, and the recessed second inner mounting groove allows the partition to be directly inserted into the second inner mounting groove when installed horizontally.

[0009] Preferably, a first inner mounting groove is provided on the other side of the movable groove, and the interior of the first inner mounting groove is connected to the outer slot of the inner baffle. The first inner mounting groove is used to fill the position of the movable groove when the partition slides laterally out of the outer frame, through the slot connection between the inner baffle and the first inner mounting groove.

[0010] Preferably, a fixing post is provided at each of the four corners of the outer mounting groove, and the fixing post is welded and fixed to the outer frame. The four corners of the outer baffle are provided with through holes that are adapted to the fixing post. The fixing post at the four corners can facilitate the fixing of the outer baffle, and the fixing of the outer baffle can facilitate the fixing of the partition.

[0011] Preferably, a nut is provided on the outside of the fixed column, and the inside of the nut is engaged with the internal thread of the fixed column. After the nut is rotated to fit against the outer baffle on the outside of the fixed column, it can facilitate further fixing of the outer baffle, improve the sealing and restriction effect on the movable groove position, and prevent liquid and gas from leaking out from the movable groove position.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When one of the three partitions needs cleaning, the partition can be gripped and pulled laterally via the handle on the side, allowing it to extend from the movable slot for easy removal. During partition installation, the outer baffle engages with the outer mounting slot, and the inner baffle engages with the second inner mounting slot, facilitating installation and improving stability. Furthermore, during lateral movement, the inner baffle slides and engages with the first inner mounting slot, completely filling the movable slot as the partition protrudes from the outer frame, preventing gas and liquid from leaking out when the partition extends laterally. The entire structure facilitates maintenance by personnel. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 and Figure 2As shown, a multi-layer baffle desulfurization and dust removal device of this embodiment includes an outer frame 1. A discharge pipe 2 is provided at the upper end of the outer frame 1, a gas conveying pipe 4 is provided on one side of the outer frame 1, and a liquid discharge pipe 3 is provided at the lower end of the outer frame 1. After the gas to be desulfurized and dust removed is sent into the interior of the outer frame 1 through the gas conveying pipe 4, it flows from bottom to top after desulfurization and dust removal and is transported toward the discharge pipe 2. The gas after desulfurization and dust removal is transported and discharged through the discharge pipe 2.

[0023] Furthermore, a second liquid inlet pipe 10 is horizontally arranged at the upper end of the inner frame 1, and a first liquid inlet pipe 5 is arranged at the upper end of the gas inlet pipe 4. The first liquid inlet pipe 5 and the second liquid inlet pipe 10 are sealed together. A nozzle 11 is arranged at the lower end of the second liquid inlet pipe 10. After the liquid required for desulfurization and dust removal is transmitted through the first liquid inlet pipe 5 and the second liquid inlet pipe 10, the liquid is discharged from the nozzle 11. It can directly discharge the gas discharged from the gas inlet pipe 4 and complete the desulfurization and dust removal. The liquid discharged from the nozzle 11 is finally discharged from the drain pipe 3.

[0024] In this embodiment, as Figure 3 As shown, three partitions 15 are evenly distributed longitudinally in the middle of the outer frame 1. One end of each partition 15 is provided with a movable groove 13, which extends through and to the side of the outer frame 1. The movable groove 13 facilitates the installation and removal of the partitions 15.

[0025] To facilitate the installation of the partition 15, an outer baffle 6 is provided on one side of the movable groove 13, and the outer baffle 6 is welded and fixed to the partition 15. An inner baffle 16 is provided at the other end of the partition 15, and the inner baffle 16 is welded and fixed to the partition 15. The welding and fixing of the inner baffle 16 and the outer baffle 6 facilitates the installation and disassembly of the partition 15, and also facilitates the fixing of the partition 15.

[0026] It is worth mentioning that, such as Figure 4 , Figure 5 and Figure 6 As shown, an external mounting groove 12 is provided on one side of the movable groove 13, and the interior of the external mounting groove 12 is connected to the external slot of the outer baffle 6. After the partition 15 is installed, the outer baffle 6 is locked inside the external mounting groove 12. The outer baffle 6 being locked inside the external mounting groove 12 can restrict the movable groove 13 and prevent the gas and liquid transmitted inside the outer frame 1 from leaking out.

[0027] A second inner mounting groove 17 is provided on one side of the outer side of the inner baffle 16, and the second inner mounting groove 17 is recessed inside the outer frame 1. The outer side of the inner baffle 16 is connected to the inner slot of the second inner mounting groove 17. When the outer baffle 6 slides and is locked inside the outer mounting groove 12, the inner baffle 16 is locked inside the second inner mounting groove 17. The combination of the inner baffle 16 and the second inner mounting groove 17 with the outer baffle 6 and the outer mounting groove 12 can facilitate the installation of the partition 15.

[0028] In order to facilitate the lateral sliding of the partition 15 outside the outer frame 1, a first inner mounting groove 14 is provided on the other side of the movable groove 13. The interior of the first inner mounting groove 14 is connected to the outer slot of the inner baffle 16. After the partition 15 slides laterally, the inner baffle 16 can replace the outer baffle 6 to fill the position of the movable groove 13.

[0029] To facilitate the fixing of the partition 15, fixing posts 7 are provided at the four corners of the outer mounting groove 12, and the fixing posts 7 are welded to the outer frame 1. The four corners of the outer baffle 6 are provided with through holes that are compatible with the fixing posts 7. After the partition 15 is installed into the outer frame 1 by sliding laterally, the fixing posts 7 can penetrate the outer baffle 6. Nuts 8 are provided on the outside of the fixing posts 7. The inside of the nuts 8 is engaged with the inside threads of the fixing posts 7. After the fixing posts 7 penetrate the outer baffle 6, the fixing posts 7 can be fixed by rotating the nuts 8.

[0030] To facilitate the lateral disassembly and installation of the outer baffle 6 and the partition 15, a handle 9 is provided in the middle of one side of the outer baffle 6, and the handle 9 is welded and fixed to the outer baffle 6. The partition 15 can be easily pulled through the protruding handle 9.

[0031] Working principle: When using the device for desulfurization and dust removal, the desulfurization and dust removal liquid is transported by the first liquid delivery pipe 5 and sent into the second liquid delivery pipe 10. The liquid transported through the second liquid delivery pipe 10 is finally sprayed out from the nozzle 11. The flue gas is transported through the gas delivery pipe 4 to the lower end of the outer frame 1. The gas flows upward towards the discharge pipe 2, and the liquid, after being sprayed out from the nozzle 11, flows downward towards the discharge pipe 3. When the gas passes through the baffle 15, foreign objects will stick to the surface of the baffle 15. When cleaning the corresponding baffle 15, the nut 8 on the outside of the fixing column 7 is turned, and the handle 9 pulls the outer baffle 6, causing the baffle 15 to move laterally. Plate 15 can extend out of the outer frame 1 from the position of movable slot 13. As the outer baffle 6 continues to move laterally, the inner baffle 16 slides laterally into the first inner mounting slot 14. This allows the inner baffle 16 to fill the position of movable slot 13 and also allows the partition 15 to be completely exposed outside the outer frame 1. The exposed partition 15 can be exposed and cleaned and treated as necessary without hindering desulfurization and dust removal. In the subsequent desulfurization and dust removal process, the fixing column 7 and nut 8 are fixed to the side of the outer frame 1. This can avoid the high temperature affecting the connection effect and also avoid excessive proximity to high heat positions, making it difficult to rotate and disassemble the partition 15.
