Description

Technical Field

[0001] This utility model relates to the field of wet electrostatic precipitators, specifically a circular wet electrostatic precipitator device. Background Technology

[0002] A wet electrostatic precipitator is a type of electrostatic precipitator that cleans the collecting electrodes by spraying or overflowing water to form a water film on the electrode surface. Similar to dry electrostatic precipitators, wet precipitators use high voltage to ionize the air around the electrodes, generating corona discharge and charging the dust particles. Under the influence of the electric field, the charged dust migrates towards the collecting electrode and is captured. However, in a wet electrostatic precipitator, the captured dust is sprayed to form a slurry, effectively preventing secondary dust re-entrainment.

[0003] Traditional wet electrostatic precipitators are fixed by welding. Since the various parts of the structure are usually welded and assembled on site, the construction site requirements are high. The welding and assembly of large equipment requires a large operating space and is subject to the limitations of the site environment, such as narrow space and difficulty in working at height. This leads to high installation difficulty and slow progress. The welding connection method makes it difficult to adjust and modify the equipment once it is assembled, resulting in poor flexibility. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a circular wet electrostatic precipitator. The external frame can be disassembled into several independent structures, which facilitates transportation. It is not only easier to install, but also simple and quick to install, with good flexibility and high stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular wet electrostatic precipitator, comprising an outer frame, wherein the outer frame is configured as a circular structure, the outer frame includes a bottom shell for air intake, a top shell for air exhaust, and several outer shells, with connecting rings welded to one end of the bottom shell, one end of the top shell, and both ends of the several outer shells, the several connecting rings, the bottom shell, the top shell, and the several outer shells are stacked together, such that there is tight contact between every two connecting rings, and several locking mechanisms for positioning are installed on the outer side of every two connecting rings, and an arc-shaped connector A and connector B are installed on the outer side of each locking mechanism, the inner side of connector A having a slot adapted to connector B, and several connectors A and connector B surrounding the outer side of the outer frame.

[0006] Preferably, each of the connecting rings has an annular mounting groove inside, and an annular component for improving stability is slidably mounted on the inner wall of each set of mounting grooves.

[0007] Preferably, the locking mechanism includes a fixed block A, a fixed block B, a telescopic rod, a spring A, and a protrusion A. Both fixed blocks A and B have cavities inside. The telescopic rod and spring A are located inside the cavity of fixed block A. The two ends of the telescopic rod are fixedly connected to fixed blocks A and B, respectively. Spring A is located on the outside of the telescopic rod, and the two ends of spring A are fixedly connected to fixed blocks A and B, respectively. The outermost part of protrusion A is slidably connected to the cavity of fixed block B, and the two are in contact. Both fixed blocks A and B are welded to their adjacent connecting rings.

[0008] Preferably, one end of the protrusion A is cylindrical, and the other end is a frustum structure.

[0009] Preferably, the fixed block B has a groove inside, and a protrusion B is slidably connected inside the groove. The protrusion B is fixedly connected to the connector A and the connector B. One side of the protrusion B is an inclined surface and fits against the frustum structure of the protrusion A. A pull rod is fixedly connected to one side of the protrusion B. One end of the pull rod passes through the fixed block B and is slidably connected to the fixed block B. A spring B is fixedly installed between the protrusion B and the inner wall of the groove.

[0010] Preferably, a ball bearing is rotatably mounted on one end of the protrusion A.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The external frame can be disassembled into an independent structure consisting of a bottom shell, a top shell, and several outer shells. The bottom shell, top shell, and several outer shells are manufactured independently, allowing for precise production and quality control in the factory. The relatively stable production environment in the factory ensures the quality and precision of the external frame. Moreover, the independent structure facilitates transportation, allowing each component to be transported to the site separately, avoiding the difficulties and risks associated with transporting large, integrated equipment. Through the locking mechanism, when the cavities of protrusion A and fixed block B are on the same axis, the elastic deformation force of springs A and B enables protrusions A and B to cooperate and automatically lock, preventing misalignment during installation. Installation is simple and quick, with good flexibility. Furthermore, it is not necessary to deliberately align protrusion A with the cavity inside fixed block B during installation, reducing installation difficulty and improving installation progress.

[0013] 2. Compared to square wet-cell products, this product has more uniform air distribution. For the same processing capacity, round wet-cell products require fewer tubes than square wet-cell products, which can effectively reduce operating costs. Attached Figure Description

Detailed Implementation

[0020] like Figures 1-5As shown, a circular wet electrostatic precipitator includes an outer frame 1, which is circular in structure. The outer frame 1 includes a bottom shell 101 for air intake, a top shell 102 for exhaust, and several outer shells 103. The outer frame 1 can be disassembled into independent structures of the bottom shell 101, top shell 102, and several outer shells 103, and can be manufactured independently. This ensures the quality and precision of the outer frame 1 and facilitates transportation, allowing each component to be transported separately to the site, avoiding the difficulties and risks associated with transporting large, integrated equipment. Connecting rings 2 are welded to one end of the bottom shell 101, one end of the top shell 102, and both ends of the several outer shells 103. The connecting rings 2, the bottom shell 101, the top shell 102, and the several outer shells 103 are stacked together. This ensures tight contact between every two connecting rings 2. Each connecting ring 2 has an annular mounting groove 7 inside. An annular component 8 for improved stability is slidably mounted on the inner wall of each set of mounting grooves 7. Every two contacting connecting rings 2 form a group and are symmetrically arranged. During installation, the annular component 8 is inserted into the mounting groove 7 of one connecting ring 2, and the mounting groove 7 of the other connecting ring 2 is fitted onto the other end of the annular component 8. Installation is convenient and quick, facilitating the initial fixation of the external frame 1. Several locking mechanisms 3 for positioning are installed on the outer side of every two connecting rings 2. The locking mechanism 3 includes a fixing block A301, a fixing block B302, a telescopic rod 303, a spring A304, and a protrusion A305. The spring A304... In the compressed state, both fixed blocks A301 and B302 have cavities inside. The telescopic rod 303 and spring A304 are located within the cavity of fixed block A301. Both ends of the telescopic rod 303 are fixedly connected to fixed blocks A301 and B302 respectively. Spring A304 is located outside the telescopic rod 303, and both ends of spring A304 are fixedly connected to fixed blocks A301 and B302 respectively. The outermost part of protrusion A305 is slidably connected to the cavity of fixed block B302, and the two are in contact. Both fixed blocks A301 and B302 are welded to their adjacent connecting rings 2. One end of protrusion A305 is cylindrical, and the other end is a frustum structure. A ball bearing 12 is rotatably mounted on one end of protrusion A305. The fixed block B302 has a groove inside, and a protrusion B9 is slidably connected inside the groove. The protrusion B9 is fixedly connected to the mating joint A4 and mating joint B5. One side of the protrusion B9 is a bevel and fits into the frustum structure of the protrusion A305. A pull rod 10 is fixedly connected to one side of the protrusion B9. One end of the pull rod 10 passes through the fixed block B302 and is slidably connected to the fixed block B302. A spring B11 is fixedly installed between the protrusion B9 and the inner wall of the groove. The spring B11 is in a static state. Each locking mechanism 3 has an arc-shaped mating joint A4 and mating joint B5 installed on its outer side. The mating joint A4 has a slot 6 that matches the mating joint B5 inside. Several mating joints A4 and B5 surround the outer side of the outer frame 1.

[0021] Working principle:

[0022] During installation, the bottom shell 101 is first fixed to the bearing surface, and one of the annular pieces 8 is inserted into the connecting ring 2 at the bottom shell 101. Then, one of the connecting rings 2 at the outer shell 103 is fitted onto the connecting ring 2. At this time, the two connecting rings 2 are in close contact, and the annular piece 8 acts as a limiter for the two connecting rings 2, preventing them from detaching. This, in turn, prevents the outer shell 103 from detaching from the bottom shell 101, achieving initial stability between the outer shell 103 and the bottom shell 101. After the two connecting rings 2 are in contact, when the protrusion A305 is inserted into the cavity at the fixing block B302, the telescopic tube and the protrusion A305 act as a limiter for the fixing block B302, raising the fixing block A301 and the fixing block B302. The stability between the two connecting rings 2 is improved because the fixing blocks A301 and B302 are fixed to the two connecting rings 2 respectively, thereby improving the stability between the bottom shell 101 and the outer shell 103 and preventing misalignment. When the protrusion A305 is inserted into the fixing block B302, the inclined surface of the protrusion A305 will contact the inclined surface of the protrusion B9. The elastic force of the spring A304 should overcome the resistance of the spring B11 and make the inclined surface of the protrusion A305 press against the inclined surface of the protrusion B9, causing the protrusion B9 to move away from the protrusion A305. At this time, the spring B11 begins to compress. Since one end of the protrusion A305 is frustum-shaped, the contact area between the protrusion A305 and the protrusion B9 is small. The lower friction between the two makes it easier for protrusion A305 to move. When protrusion A305 passes over protrusion B9 and moves below it, protrusion B9 returns to its original position under the elastic deformation of spring B11. At this time, protrusion B9 presses against the upper surface of protrusion A305, limiting its movement and making the connection between the outer shell 103 and the bottom shell 101 more stable. It should be noted that when installing the outer shell 103 onto the bottom shell 101, it is not necessary to deliberately align protrusion A305 with the cavity inside the fixing block B302. For example, when protrusion A305 is above the connector A4, the bottom end of protrusion A305 will contact and compress the connector A4, further compressing spring A304 and providing cushioning. This design reduces the probability of damage caused by collisions during installation between the bottom shell 101 and the outer shell 103. Furthermore, at this time, the connector A4 is located within the slot 6 of the connector B5. Then, the outer shell 103 is rotated slightly, causing the ball bearing 12 at the bottom of the protrusion A305 to roll along the connector A4, and the connector B5 to move along the slot 6 of the connector A4. The ball bearing 12 reduces resistance during rotation. When the connector B5 moves to a position where it abuts against the inner wall of the slot 6, the protrusion A305 should be aligned with the cavity of the fixing block B302, facilitating the insertion of the protrusion A305 into the cavity of the fixing block B302. This reduces installation difficulty and increases installation progress. Additionally, the sides of the connector A4 and connector B5 should be in contact.The annular structure formed by several mating joints A4 and B5 enhances their ability to withstand lateral forces, further improving the stability between the bottom shell 101 and the outer shell 103. Following these steps, the remaining outer shell 103 and top shell 102 are then installed sequentially. The installation is simple, quick, flexible, and highly stable.

[0023] Finally, the external frame 1 structure can be decomposed into independent structures of bottom shell 101, top shell 102 and several outer shells 103. The bottom shell 101, top shell 102 and several outer shells 103 are manufactured independently, allowing for refined production and quality control in the factory. The factory's production environment is relatively stable, ensuring the quality and precision of the external frame 1. Moreover, the independent structure facilitates transportation, allowing each component to be transported to the site separately, avoiding the difficulties and risks of transporting large integrated equipment. It should be noted that the bottom of the external frame 1 is used to install the air intake device and drainage system, and its top should be equipped with an exhaust device and a spray device. A dust removal device should be installed inside to achieve the purpose of flue gas entry, dust removal, spraying and drainage, and to treat the flue gas.
