Description

Technical Field

[0001] The invention relates to the technical field of distillation tower downcomers, in particular to a multi-folded inclined downcomer for a distillation tower. Background Art

[0002] Conventional downcomers (also known as downcomers) are key components in tray-type gas-liquid contact equipment, such as distillation and absorption towers. They are typically installed on one or both sides of a tray. Their core functions include: guiding liquid flow: smoothly directing liquid from the upper tray to the lower tray, ensuring continuous mass and heat transfer; gas-liquid separation: the brief residence time of liquid in the downcomers releases entrained bubbles and reduces mist entrainment; and liquid sealing: preventing gas from the lower tray from short-circuiting through the downcomers, thereby maintaining the pressure differential and efficiency within the tower. Most common trays utilize vertical or inclined arched downcomers, which can easily lead to uneven gas-liquid flow distribution across the tray. At the downcomer outlet, high liquid velocity and high static pressure head make it difficult for gas to pass through, creating a dead zone for gas flow. On both sides of the tray, minimal liquid exiting the downcomers creates dead zones for liquid flow. These dead zones reduce the effective bubbling area, shortening gas-liquid contact time and resulting in inefficient gas-liquid separation. Summary of the Invention

[0043] Preferably, the second section of the plate is connected to another main downcomer plate 101a below, and the main downcomer plate 101a below has an opening at the center to facilitate liquid flow. When the liquid flows, the liquid flows from the downcomer gap 102c to the other main downcomer plate 101a below, and the liquid flows toward the center of the main downcomer plate 101a below, and then flows to the opening at the center of the main downcomer plate 101a, and then flows to the next main downcomer plate 101a, and then the liquid flows again on both sides of the next main downcomer plate 101a.

The rotating disk 402 is provided on the fixed cylinder 401, and the rotating axis of the rotating disk 402 passes downward through the center position of the fixed cylinder 401 and extends out. After extending out, it is connected downward to the lower surface of the main downcomer plate 101a. A box body 402b is provided on the lower surface of the main downcomer plate 101a, and a stepping motor for controlling the rotation of the rotating disk 402 is provided in the box body 402b.

[0050] Preferably, a flip member 404 is provided between the connecting member 403 and the fixed cylinder 401 , and the flip member 404 controls the rotation of the connecting member 403 .

[0051] Furthermore, the connecting member 403 includes a support rod 403a rotatably connected to the side wall of the rotating disk 402 and a support block 403b provided at one end of the support rod 403a. The support block 403b is detachably connected to the support rod 403a.

[0052] Furthermore, a clamping plate 306 is provided on the support block 403b, and a change plate 307 is rotatably connected on both sides of the clamping plate 306. A counterweight 308 is provided at each change plate 307 near the support rod 403a, and a filter hole 309 is opened on the change plate 307. In this embodiment, the counterweight 308 includes a counterweight ball provided at the change plate 307 near the support rod 403a. The counterweight ball is fixedly connected to the change plate 307 and is provided at a position where the two change plates 307 are closest to the lower end of the clamping plate 306 (refer to Figure 5 ), and then the position of the counterweight ball can control the state of the change plate 307.

[0053] In this embodiment, the flip member 404 includes a guide plate 404a provided at one end of the support rod 403a extending into the interior of the rotating disk 402, a flip control wheel 404b rotatably connected to the guide plate 404a, and a guide groove 404c provided on the fixed cylinder 401. There are two flip control wheels 404b, and the guide groove 404c includes a first inclined groove 404c-1 and a second inclined groove 404c-2. The first inclined groove 404c-1 is connected to the second inclined groove 404c-2, and An included angle is formed between the first inclined groove 404c-1 and the second inclined groove 404c-2. A matching conical block 405 is provided opposite the first inclined groove 404c-1 and the second inclined groove 404c-2. The upper surface of the matching conical block 405 is also inclined and corresponds to the first inclined groove 404c-1 and the second inclined groove 404c-2. The straight-line distance between the lower end of the matching conical block 405 and the lower end of the fixed cylinder 401 matches the diameter of the flip control wheel 404b.

[0054] Preferably, the straight-line distance between the two flip control wheels 404 b is greater than the hypotenuse length of the matching tapered block 405 .

[0055] Preferably, the flip control wheel 404b is always in contact with the lower end edge of the fixed cylinder 401. When the rotating disk 402 continues to rotate, it will drive the movement of the support rod 403a and synchronously drive the movement of the guide plate 404a. When the guide plate 404a drives the flip control wheel 404b to move to the position of the matching conical block 405, the flip control wheel 404b at the front end will enter the first inclined groove 404c-1, and then the guide plate 404a will be rotated, thereby driving the rotation of the support rod 403a, thereby rotating the splint 306.

[0056] Preferably, a square slot 406 is provided at the connection between the first inclined slot 404c-1 and the second inclined slot 404c-2. When one of the flip control wheels 404b gradually moves in the first inclined slot 404c-1, it will be stuck in the slot 406. At this time, the second flip control wheel 404b has not yet entered the first inclined slot 404c-1, and the rotating disk 402 is still rotating at the same time, which will cause the entire connecting member 403 to rotate relative to the first flip control wheel 404b as the rotation center. The rod 403a rotates 180 degrees to complete the flipping of the clamping plate 306, and then causes the first bubble frame plate 302 and the second bubble frame plate 303 to continuously flip, thereby causing the liquid to be continuously stirred. The stirring direction includes the rotation direction of the rotating disk 402 and the rotation direction of the changing plate 307. The rotation direction of the rotating disk 402 is horizontal, while the changing plate 307 is longitudinal. As a result, the liquid has velocity components in two directions, thereby increasing the height of the foam layer, prolonging the gas-liquid contact time, and improving the mass transfer efficiency.

[0057] Preferably, a micro-sliding baffle 407 is provided in the card slot 406, and the micro-sliding baffle 407 can slide to close the card slot 406. Preferably, an electromagnet is provided on the upper end of the micro-sliding baffle 407, and the operator's overall control of the power on or off of the electromagnet can be automatically realized through existing electrical control methods. When the power is turned on, the electromagnet is magnetized and will be attracted to the half magnet in the card slot 406, thereby exposing the card slot 406. When the power is turned off, the electromagnet loses its magnetism, and the micro-sliding baffle 407 closes the card slot 406 under the action of gravity. As a result, the flip control wheel 404b will not enter the slot 406 after moving, and the support rod 403a will not rotate with the flip control wheel 404b as the rotation center, but only a certain deflection will occur. At this time, the change plate 307 will not flip, but will only rise up a certain distance, and the liquid will not be stirred at this time, thereby reducing a certain amount of gas-liquid contact time. This mode can be selected when performing gas-liquid separation on different liquids.

[0058] Operation process: When one of the flip control wheels 404b gradually moves in the first inclined groove 404c-1, it will be stuck in the slot 406. At this time, the second flip control wheel 404b has not yet entered the first inclined groove 404c-1, and the rotating disk 402 is still rotating at the same time, which will cause the entire connecting part 403 to rotate relative to the first flip control wheel 404b as the rotation center. At this time, the support rod 403a will rotate 180° to complete the flipping of the splint 306, thereby realizing the flipping or rotation of the changing plate 307, thereby increasing the mass transfer efficiency.
