Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of gas-water separators, and in particular relates to a double-hook corrugated plate gas-water separator. Background Art
[0002] In a double-hook corrugated plate separator, the design of the hydrophobic hook can generate eddies in the flow field, effectively increasing the separation efficiency of small-particle droplets. For example, "CN112999759A-A New Blade-Type Demister" discloses a double-hook corrugated plate separator structure in which all hydrophobic hooks are at equal vertical distances from the corrugated plate main board. However, the structure of the hydrophobic hook will increase the disturbance to the flow field and reduce the flow area of the flow field, which will lead to an increase in pressure loss. In a double-hook corrugated plate separator structure, large-particle droplets rely on inertia to achieve gas-liquid separation, and most of the large-particle droplets will be collected by the corrugated plate separator in the first two stages. The droplets accumulate in large quantities on the outer wall of the corrugated plate hydrophobic hook to form a liquid film. Under the action of the mainstream gas, the liquid film easily generates secondary droplets at the end of the hydrophobic hook, and the large-particle droplets splash when they hit the water film. Under the action of the main airflow, secondary droplets will also be generated, which will eventually affect the separation efficiency of the corrugated plate. Summary of the Invention
[0003] In order to solve the problem of reduced separation efficiency of the corrugated plate due to the generation of secondary droplets and reduce operating costs, the present invention takes into account the influence of the existence of secondary droplets and designs the shape and size of the double-hook corrugated plate separator by the idea of graded separation of droplets of different particle sizes. It designs a steam-water separator structure in which the first two stages mainly separate large-particle droplets and can reduce the generation of secondary droplets, while having the functions of reducing separation pressure drop and increasing overall separation efficiency.

[0007] Compared with the existing technology, the beneficial effects of this technical solution are:
[0008] 1. Adjust the hydrophobic hook structure to achieve the function of separating and grading droplets of different particle sizes:
[0009] For large-sized droplets, since most of the large-sized droplets will be collected by the corrugated plate separator in the first two regions (i.e., the second-stage hydrophobic hooks and the third-stage hydrophobic hooks in the embodiment of this solution), a large amount of liquid film is easily formed on the hydrophobic hooks of the corrugated plate. The liquid film is likely to generate secondary droplets under the action of the mainstream gas. The present invention adjusts the hook length and height of the hydrophobic hooks in the first two regions of the corrugated plate to change the flow trajectory of the droplets, so that the large-sized droplets directly collide with the hydrophobic hooks. A large amount of liquid film is formed on the inner side of the hydrophobic hooks and separated from the mainstream gas. In the absence of the mainstream gas, even if the droplets collide with the liquid film and splash, they will not be brought into the mainstream field, which can effectively reduce the generation of secondary droplets.
[0010] 2. For small-sized droplets, the height of the hydrophobic hooks after the corrugated plate is increased, and an unequal height structure is adopted. By increasing the disturbance of the mainstream gas, the hydrophobic area inside the hydrophobic hook is increased, and a large-scale vortex is formed inside the hydrophobic hook, so that more small-sized droplets are trapped in the hydrophobic hook, thereby increasing the separation efficiency of small-sized droplets.
[0011] 3. The second, third, and fourth-stage hydrophobic hooks have been given rounded corners. Compared to existing zigzag structures, these rounded corners can effectively reduce separation pressure drop and flow field disturbances, while also having a minimal impact on the separation of small droplets. In summary, the present invention, while taking into account the impact of secondary droplets on droplet separation, has designed a dual-hook corrugated plate steam-water separator that can achieve graded separation of droplets of different particle sizes, while reducing separation pressure drop and increasing overall separation efficiency.

[0026] like Figure 5 As shown in the figure, the flow trajectories of droplets of 5 μm and 50 μm respectively in the corrugated plate provided by the present invention, when the airflow passes through the main plate of the corrugated plate, the large-particle droplets will be collected by the corrugated plate separator in the first two areas of the separator (i.e., the second-stage hydrophobic hook 7 and the third-stage hydrophobic hook 8), and the collected droplets form a large amount of liquid film in the hydrophobic hook of the corrugated plate, which is discharged through the hydrophobic hook under the action of gravity. The small-particle droplets are mainly separated in the last few stages of the corrugated plate separator, and a large-scale vortex is formed in the hydrophobic hook of the corrugated plate separator. The small-particle droplets enter the hydrophobic hook along with the vortex, are separated from the mainstream field, and are trapped in the hydrophobic hook, and are finally collected by the separator.
[0027] The structural dimensions of conventional double-hook corrugated plate steam-water separator are as follows: Figure 1 and Figure 2 shown.
[0028] The following is a comparison of the experimental results of the double-hook corrugated plate steam-water separator embodiment provided by the present invention and the conventional double-hook corrugated plate steam-water separator structure comparison example:
[0029] like Figure 6As shown in the figure, (a) is the double-hook corrugated plate steam-water separator provided by the present invention, and (b) is a conventional double-hook corrugated plate steam-water separator structure as a comparative example. For large-particle droplets, since most of the large-particle droplets will be collected by the corrugated plate separator in the first two levels, in comparative example (b), most of the droplets will hit the outer wall surface 18 of the hydrophobic hook and be collected. At this time, a large amount of liquid film is easily formed on the outer wall surface of the hydrophobic hook of the corrugated plate. The mainstream gas is larger at the outer wall surface, and the liquid film is more likely to produce secondary droplets under the action of the mainstream gas. In contrast, embodiment (a) of the present invention adjusts the hook length and height of the hydrophobic hook, changes the flow trajectory of large-particle droplets, and most of the large-particle droplets directly flow into the hydrophobic hook 19, hit the inner wall surface of the corrugated plate and are collected, so that the liquid film is mainly formed in the hydrophobic hook and separated from the mainstream gas. As shown in FIG. Figure 7 As shown, in Example (a) of the present invention, only a small amount of gas enters the hydrophobic hook, and the flow rate inside the hydrophobic hook is low. The low flow rate of gas inside the hydrophobic hook has little impact on the liquid film. Even if droplets impact the liquid film and splash, they are unlikely to be brought back into the mainstream field, which can effectively reduce the generation of secondary droplets. Comparative Example (b) is prone to secondary droplets.
[0030] Since the embodiment of the present invention adds a rounded corner structure to the second, third and fourth stage hydrophobic hooks, this structure can effectively reduce the separation pressure drop compared to the broken line design at the same inlet velocity. Figure 8 As shown, when the speed is above 3 m / s, the separation pressure drop of the embodiment of the present invention is significantly reduced. When the speed is 5 m / s, the pressure drop is reduced by 20% compared with the control example. At the same time, most of the water can still be removed, which significantly reduces the operating cost.
[0031] Since the embodiment of the present invention increases the height of the hydrophobic hooks in the latter stages and sets the straight hooks and the curved hooks into unequal height structures, the separation efficiency of small particle size droplets is increased. Figure 9 and Figure 10 As shown, the separation efficiency of different particle sizes of the comparative example and the embodiment of the present invention at v = 3m / s and v = 5m / s is increased. By increasing the hook length of the hydrophobic hook to increase the disturbance of the mainstream gas, a larger range of vortex is formed in the hydrophobic hook, so that more small particle droplets are trapped in the hydrophobic hook. When v = 3m / s, the separation efficiency of small particle droplets is significantly improved. When v = 5m / s, the separation efficiency of small particle droplets is less improved, but the overall separation efficiency is not reduced due to the reduction in pressure drop, and the separation requirements can also be met and the operating costs can be reduced.
[0032] In summary, the beneficial effects of this technical solution are:
[0033] 1. Adjust the hydrophobic hook structure to achieve the function of separating and grading droplets of different particle sizes:
[0034] For large-sized droplets, since most of the large-sized droplets will be collected by the corrugated plate separator in the first two regions (i.e., the second-stage hydrophobic hooks and the third-stage hydrophobic hooks in the embodiment of this solution), a large amount of liquid film is easily formed on the hydrophobic hooks of the corrugated plate. The liquid film is likely to generate secondary droplets under the action of the mainstream gas. The present invention adjusts the hook length and height of the hydrophobic hooks in the first two regions of the corrugated plate to change the flow trajectory of the droplets, so that the large-sized droplets directly collide with the hydrophobic hooks. A large amount of liquid film is formed on the inner side of the hydrophobic hooks and separated from the mainstream gas. In the absence of the mainstream gas, even if the droplets collide with the liquid film and splash, they will not be brought into the mainstream field, which can effectively reduce the generation of secondary droplets.
[0035] 2. For small-sized droplets, the height of the hydrophobic hooks after the corrugated plate is increased, and an unequal height structure is adopted. By increasing the disturbance of the mainstream gas, the hydrophobic area inside the hydrophobic hook is increased, and a large-scale vortex is formed inside the hydrophobic hook, so that more small-sized droplets are trapped in the hydrophobic hook, thereby increasing the separation efficiency of small-sized droplets.
[0036] 3. The second, third, and fourth-stage hydrophobic hooks have been given rounded corners. Compared to existing zigzag structures, these rounded corners can effectively reduce separation pressure drop and flow field disturbances, while also having a minimal impact on the separation of small droplets. In summary, the present invention, while taking into account the impact of secondary droplets on droplet separation, has designed a dual-hook corrugated plate steam-water separator that can achieve graded separation of droplets of different particle sizes, while reducing separation pressure drop and increasing overall separation efficiency.
