Description

Technical Field

[0001] This utility model relates to the technical field of desulfurization tower demisters, specifically to a desulfurization tower demister and an anti-clogging structure. Background Technology

[0002] In industrial production, especially in desulfurization tower applications involving flue gas treatment, the demister stage is crucial. Traditional desulfurization tower demisters mostly employ flat or corrugated plate structures, with baffles typically being single-plane or simply corrugated. During long-term operation of the desulfurization tower, impurities easily accumulate between the baffles, such as dust, particulate matter, and precipitates generated from chemical reactions in the flue gas. As impurities accumulate, the gaps between the baffles gradually become blocked, severely affecting the normal ventilation and demisting functions of the demister, leading to a decrease in the overall operating efficiency of the desulfurization tower, and even causing equipment failure, increasing maintenance costs and downtime. Therefore, developing a desulfurization tower demister with anti-clogging capabilities has become an urgent problem to be solved in the industry. Utility Model Content

[0003] The purpose of this utility model is to provide a technical solution for a desulfurization tower demister and an anti-clogging structure to address the shortcomings mentioned in the background art. To overcome the drawbacks and defects described in the background art, this technical solution includes the following: The desulfurization tower demister includes a baffle-type demister mechanism, which comprises multiple baffle plates arranged horizontally at equal intervals, and six support rods arranged longitudinally and fixed to the upper and lower surfaces of the baffle plates. The vertical cross-section of each of the baffle plates is wavy, and there are gaps between each baffle plate to allow mist to flow through the desulfurization tower. The end face of each support rod near the baffle plate is provided with a groove that can be inserted into the baffle plate.

[0004] The desulfurization tower demister has an anti-clogging structure, which includes a gap anti-clogging mechanism. This mechanism comprises a semi-circular ring, multiple rigid tubes arranged in a ring array and equidistantly embedded inside the semi-circular ring, and multiple jet nozzles fixed to the inner ends of the rigid tubes. Three arc-shaped tubes are arranged on the outer side of the semi-circular ring, with their inner ends connected to the outer ends of the rigid tubes. A vertically arranged connecting pipe runs through the interior of each arc-shaped tube, and a booster pump is connected to the bottom end of the connecting pipe. It should be noted that the inner wall of the desulfurization tower has a chamber for the gap anti-clogging mechanism to protrude and be installed.

[0005] As a preferred embodiment of this utility model, the inner sidewall of the semi-circular ring is fixedly connected to the outer sidewall of the baffle plate.

[0006] As a preferred embodiment of this utility model: multiple through holes are provided on the inner end face of the arc-shaped tube for the outer end of the rigid tube to pass through, and the inside of the through holes is filled with sealant.

[0007] As a preferred embodiment of this utility model, the inner cavities of the connecting pipe and the arc-shaped pipe are interconnected.

[0010] As a preferred embodiment of this utility model: the inlet port of the booster pump, which is far from the connecting pipe, is connected to an external water source through a water pipe.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: In the baffle-type demister mechanism, multiple wavy, vertically cross-section baffle plates are arranged equidistantly with gaps. This allows liquid droplets to collide with and change direction as mist passes through the desulfurization tower, adhering to the plates and flowing down under gravity, achieving efficient gas-liquid separation and improving the demister effect. Support rods stabilize the baffle plates through grooves, ensuring stable operation of the demister structure. In the anti-clogging structure's gap-prevention mechanism, a booster pump draws and pressurizes external water, delivering it through a connecting pipe, an arc-shaped pipe, and a rigid pipe to the jet nozzle. The jet nozzle inserts into the gaps in the baffle plates, and the jet flow penetrates the gaps, flushing away impurities and preventing clogging, ensuring unobstructed flow. A semi-circular clasp is fixed to the outside of the baffle plates, and the rigid pipe is securely installed through a sealing structure, ensuring the stability and reliability of the entire anti-clogging structure and extending the demister's service life.

[0016] Example 1: The desulfurization tower demister in this example includes a baffle-type demister mechanism 1. This baffle-type demister mechanism 1 comprises multiple baffle plates 1-1 arranged laterally at equal intervals, and six support rods 1-2 arranged longitudinally and fixed to the upper and lower surfaces of the baffle plates 1-1. The vertical cross-section of the baffle plates 1-1 is wavy, with gaps between them to allow mist to flow within the desulfurization tower. The end faces of the support rods 1-2 near the baffle plates 1-1 are provided with grooves that engage with the baffle plates 1-1.

[0017] Meanwhile, this embodiment also includes an anti-clogging structure for the desulfurization tower demister. This anti-clogging structure is applicable to the aforementioned desulfurization tower demister and includes a gap anti-clogging mechanism 2. The gap anti-clogging mechanism 2 includes a semi-circular clasp 2-1, the inner sidewall of which is fixedly connected to the outer sidewall of the baffle plate 1-1. Multiple rigid tubes 2-3 are equidistantly embedded in the semi-circular clasp 2-1 in a ring array. Multiple circular holes for the rigid tubes 2-3 to pass through are opened inside the semi-circular clasp 2-1, and O-rings are installed inside the circular holes. Multiple jet nozzles 2-2 are fixed to the inner ends of the rigid tubes 2-3. The jet nozzles 2-2 are respectively inserted into the gaps between the baffle plates 1-1, and the jet direction penetrates the gaps between the baffle plates 1-1. Three arc-shaped tubes 2-6 are arranged on the outer side of the semi-circular ring 2-1. Multiple through holes are opened on the inner end face of each arc-shaped tube 2-6 for the outer end of the rigid tube 2-3 to pass through. The through holes are filled with sealant. The inner end face of the arc-shaped tube 2-6 is connected to the outer end of the rigid tube 2-3. A vertically arranged connecting tube 2-5 passes through the interior of the arc-shaped tube 2-6. The inner cavities of the connecting tube 2-5 and the arc-shaped tube 2-6 are interconnected. A booster pump 2-4 is connected to the bottom end of the connecting tube 2-5. The inlet port of the booster pump 2-4, away from the connecting tube 2-5, is connected to an external water source via a water pipe.

[0018] Example 2: The desulfurization tower demister in this example also features a baffle-type demister mechanism 1, consisting of multiple horizontally arranged baffle plates 1-1 at equal intervals and six longitudinally arranged support rods 1-2 fixed to the upper and lower surfaces of the baffle plates 1-1. The vertical cross-section of the baffle plates 1-1 is wavy, with gaps between them for mist flow. The support rods 1-2 are inserted into the baffle plates 1-1 through end face grooves. In the anti-clogging structure of the desulfurization tower demister, the semi-circular cladding ring 2-1 of the gap anti-clogging mechanism 2 is fixed to the outer sidewall of the baffle plate 1-1. Multiple rigid tubes 2-3 are arranged in a ring array and equidistantly embedded in the semi-circular cladding ring 2-1, and are fixed through round holes with O-ring seals on the semi-circular cladding ring 2-1. The jet nozzles 2-2 at the inner ends of the rigid tubes 2-3 are inserted into the gaps of the baffle plates 1-1, with the jet direction penetrating the gaps. Three arc-shaped tubes 2-6 on the outer side of the semi-circular ring 2-1 are connected to the outer end of the rigid tube 2-3 through through holes with sealant. The arc-shaped tubes 2-6 are connected to the inner cavity of the vertically arranged connecting tube 2-5. The bottom end of the connecting tube 2-5 is connected to the booster pump 2-4, and the inlet port of the booster pump 2-4 is connected to an external water source through a water pipe. Unlike Embodiment 1, the arrangement density of the rigid tubes 2-3 in this embodiment is slightly higher to meet the requirements for gap clogging under different working conditions.

[0019] Example 3: The desulfurization tower demister in this example includes a baffle-type demister mechanism 1, in which baffle plates 1-1 are arranged horizontally at equal intervals, and support rods 1-2 are arranged longitudinally and fixed to the upper and lower surfaces of the baffle plates 1-1. The vertical cross-section of the baffle plates 1-1 is wavy and has gaps for mist flow. The support rods 1-2 are connected to the baffle plates 1-1 through grooves. In the anti-clogging mechanism 2 of the desulfurization tower demister's anti-clogging structure, a semi-circular ring 2-1 is fixed to the outer sidewall of the baffle plate 1-1. Multiple rigid tubes 2-3 are embedded in the semi-circular ring 2-1 and fixed through round holes with O-ring seals. The jet nozzles 2-2 at the inner ends of the rigid tubes 2-3 are inserted into the gaps of the baffle plates 1-1, and the jet direction penetrates the gaps. Three arc-shaped tubes 2-6 on the outer side of the semi-circular ring 2-1 are connected to the outer end of the rigid tube 2-3 through a through hole with sealant. The arc-shaped tubes 2-6 are connected to the inner cavity of the vertical connecting tube 2-5. The bottom end of the connecting tube 2-5 is connected to the booster pump 2-4, and the inlet port of the booster pump 2-4 is connected to an external water source through a water pipe. Unlike the previous two embodiments, the diameter of the arc-shaped tubes 2-6 in this embodiment is relatively large, which can improve the fluid transport efficiency to a certain extent to meet the requirements of anti-clogging effect in specific scenarios.

[0020] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: During the operation of the desulfurization tower, the flue gas containing mist enters the desulfurization tower and first reaches the baffle-type demister 1. Since the baffle-type demister 1 includes multiple baffle plates 1-1 arranged laterally at equal intervals, and the vertical cross-section of the baffle plates 1-1 is wavy, with gaps between them to allow the mist to flow through. When the flue gas passes through these gaps, the droplets in the mist will adhere to the surface of the baffle plates 1-1 due to the obstruction and change in flow direction caused by the baffle plates 1-1. As the droplets continuously accumulate, under the action of gravity, the droplets will flow down along the baffle plates 1-1, thereby achieving gas-liquid separation and achieving the purpose of demisting. Six support rods 1-2, arranged longitudinally and fixed to the upper and lower surfaces of the baffle plate 1-1, engage with grooves on the baffle plate 1-1 near their end faces, stabilizing the baffle plate 1-1 and preventing it from shaking or shifting during operation, thus maintaining a stable demister structure. After prolonged operation, the gaps between the baffle plates 1-1 may become clogged due to accumulated impurities, affecting the demister effect and the normal operation of the desulfurization tower. At this time, the anti-clogging structure of the desulfurization tower demister comes into play. The booster pump 2-4 starts, drawing clean liquid from an external water source through a water pipe connected to its inlet port, pressurizing the liquid, and delivering it to the connecting pipe 2-5. Since the internal spaces of the connecting pipe 2-5 and the arc-shaped pipe 2-6 are interconnected, the pressurized liquid enters the arc-shaped pipe 2-6.

[0021] Multiple through holes are provided on the inner end face of the arc-shaped tube 2-6 for the outer end of the rigid tube 2-3 to pass through. These through holes are filled with sealant to prevent liquid leakage. Liquid enters the rigid tube 2-3 through these through holes. Multiple circular holes are provided inside the semi-circular ring 2-1 for the rigid tube 2-3 to pass through. O-rings are installed inside these holes to further prevent liquid leakage and to secure the rigid tube 2-3 within the semi-circular ring 2-1. The liquid flows within the rigid tube 2-3 and eventually reaches the jet nozzle 2-2 fixed to the inner end of the rigid tube 2-3. The jet nozzles 2-2 are inserted into the gaps between the baffle plates 1-1, and the jet direction penetrates through the gaps between the baffle plates 1-1. The liquid is ejected from the jet nozzles 2-2 at high speed to form a jet, which washes away the impurities in the gaps and removes them with the liquid flow, thereby preventing the gaps from becoming blocked and ensuring the unobstructed flow of the gaps between the baffle plates 1-1, so that the desulfurization tower demister can continue to work normally.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
