Description

Technical Field

[0001] This utility model relates to the technical field of slotted disc distributors, specifically a slotted disc distributor. Background Technology

[0002] As a key internal component of chemical towers, the tray distributor is widely used in mass and heat transfer processes such as distillation, absorption, and desorption. Its core function is to uniformly distribute the liquid onto the surface of the packed bed, providing a sufficient and efficient contact interface for the gas and liquid phases, which directly determines the separation efficiency and processing capacity of the tower. Ideal liquid distribution requires maintaining a uniform liquid flow across the entire tower cross-section to avoid undesirable distribution phenomena such as channeling and wall flow.

[0003] In existing tray-type distributors, the liquid distribution holes are typically designed as simple circular holes. While this structure is easy to manufacture, it has inherent drawbacks in practical industrial applications: after the liquid passes through the circular distribution holes, it forms a concentrated liquid column. When the number of distribution holes is insufficient, the spacing is unreasonable, or the tower is operating under non-design load, this concentrated liquid column will directly impact the packing surface, forming a "hot spot" of localized liquid overload at the point of impact. In the area between the "hot spots," "cold spots" of insufficient liquid distribution are formed. This initial uneven distribution is continuously amplified in the packing bed, significantly worsening the gas-liquid distribution state and leading to a decrease in mass transfer efficiency. Therefore, how to quickly form a larger horizontal area in the initial stage, improve the uniformity of the initial distribution, and lay a better foundation for subsequent uniform distribution in the packing is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a tray-type distributor to solve the problem mentioned in the background art where, after liquid passes through a circular distribution hole, a concentrated liquid column is formed. When the number of distribution holes is insufficient, the spacing is unreasonable, or the tower is operating under non-design load, this concentrated liquid column will directly impact the packing surface, forming a "hot spot" of local liquid overload at the point of impact. In the area between the "hot spots", "cold spots" of insufficient liquid distribution are formed. This initial uneven distribution will be continuously amplified in the packing bed, significantly worsening the gas-liquid distribution state and leading to a decrease in mass transfer efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grooved distributor, comprising a grooved disc and a valve;

[0006] The tank is provided with several liquid distribution holes;

[0007] The valve is disposed on the tray corresponding to the liquid distribution hole. The valve is composed of multiple openable and closable lobes, and gaps are formed between adjacent lobes to allow liquid to flow out.

[0008] Preferably, the tray is composed of multiple modular trays assembled together;

[0009] The mating edge of the disc is provided with a mounting block, which is connected by fasteners, and a sealing structure is provided between the mating surfaces.

[0010] Preferably, the valve has an overall frustum-shaped structure;

[0011] The outer wall of the valve has an external threaded groove.

[0012] Preferably, an adjusting gear is provided on the outer wall of the valve, the adjusting gear including a conical connecting ring and a first gear;

[0013] The inner wall of the tapered connecting ring is provided with an internal thread that matches the external thread groove;

[0014] The first gear is coaxially positioned at the top of the tapered connecting ring.

[0015] Preferably, a transmission component is provided on the inner side of the adjusting gear, the transmission component is in contact with the grooved plate, and the transmission component includes a moving block, external teeth and internal teeth;

[0016] The external teeth are disposed on the two long sides of the outer side wall of the moving block;

[0017] The internal teeth are located on one of the long sides of the inner wall of the moving block.

[0018] Preferably, a driving component is provided on the inner side of the transmission component, the driving component is connected to the slotted plate, and the driving component includes a second gear and a connecting shaft;

[0019] The second gear is disposed on the outer circumferential wall of the connecting shaft;

[0020] One end of the connecting shaft is connected to the grooved plate via a bearing.

[0021] Preferably, the surface of the transmission component is provided with a guide, the guide is connected to the driving component, and the guide includes a pressure plate, a connecting block and a mounting plate;

[0022] The side end of the pressure plate is provided with a connecting hole that matches the connecting shaft, and the connecting shaft is connected to the connecting hole through a bearing;

[0024] The mounting plate is disposed on the end of the connecting block away from the pressure plate, and the mounting plate is connected to the slot.

[0025] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting a valve at the liquid distribution hole, when the valve opens, the liquid does not flow out from a round hole, but from the gap between multiple valves, naturally forming multiple fine liquid streams. When the fine liquid streams leave the distribution hole, they can cover a larger horizontal area, which is equivalent to a miniature pre-distributor. This helps the liquid to spread on the packing bed earlier and more evenly, improving the uniformity of the initial distribution and laying a better foundation for the uniform distribution in the packing later. (2) The valve is closed and opened by moving the conical connecting ring, and the degree of opening and closing of the valve is adjusted. The valve can be opened and closed regularly to shear, squeeze and break up soft particles or polymers that are about to block, thus playing a self-cleaning role. The flow channel morphology changes during the opening and closing process of the valve structure, making it difficult to form a fixed dead corner for long-term deposition of solid materials. This greatly improves the distributor's ability to handle dirty, easily crystallized, and solid particle-containing materials, reduces the frequency of shutdown cleaning, and increases the operation cycle. (3) When the liquid load is low and the flow rate is low, the opening can be reduced to maintain sufficient liquid seal, prevent gas from short-circuiting through the distribution hole and avoid distribution failure. When the liquid load is high, the opening can be increased to ensure smooth liquid flow, prevent the liquid level in the distribution tank from overflowing due to excessive liquid level, and cause uneven distribution, thus greatly expanding the operational flexibility. (4) When the gas load increases, reducing the opening can reduce the liquid inflow and the liquid holding capacity of the packing layer, thereby delaying or avoiding the occurrence of flooding, enabling the tower to operate stably under higher gas-liquid loads, tapping the maximum potential processing capacity of the device, effectively suppressing flooding, and improving processing capacity.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This invention provides a tray-type distributor. By setting valves at the liquid distribution holes, when the valves open, the liquid does not flow out from a single circular hole, but rather from the gaps between multiple valves, naturally forming multiple fine liquid streams. These fine liquid streams, upon leaving the distribution holes, can cover a larger horizontal area, acting as a miniature pre-distributor. This helps the liquid spread more evenly and earlier on the packing bed, improving the initial distribution uniformity and laying a better foundation for subsequent uniform distribution within the packing. Please refer to [link to relevant documentation]. Figure 1-2 and Figure 4 It includes: a groove 100, a valve 200, an adjusting gear 300, a transmission component 400, a driving component 500, and a guide component 600; Example

[0030] Please see Figure 1 The surface of the tank 100 is evenly distributed with liquid distribution holes, through which liquid flows out and spreads on the packing bed;

[0031] The valve 200 can be opened and closed and installed on the surface of the tray 100. The valve 200 is composed of four or six leaflets with gaps between adjacent leaflets. The valve 200 has a conical structure that is larger at the bottom and smaller at the top. The valve 200 corresponds to the liquid distribution hole. Liquid flows into the inner cavity of the valve 200 through the liquid distribution hole and flows out through the valve 200.

[0032] When the valves open, the liquid does not flow out from a single circular hole, but rather from the gaps between multiple valves, naturally forming multiple fine liquid streams. These fine liquid streams, upon leaving the distribution holes, can cover a larger horizontal area, acting as a miniature pre-distributor. This helps the liquid spread more evenly on the packing bed earlier, improving the uniformity of the initial distribution and laying a better foundation for subsequent uniform distribution within the packing. Example

[0033] Please see Figure 1 The tray 100 is composed of four quarter-circle discs. The edges of the four quarter-circle discs are integrally formed with mounting blocks 110. The adjacent mounting blocks 110 fit together and are fixed by bolts and nuts. The mounting blocks 110 are sealed together. Compared with the traditional integral tray 100, the split tray 100 greatly reduces the installation difficulty of large trays in confined spaces, improves construction efficiency, facilitates subsequent maintenance and partial replacement, effectively reduces downtime and lowers the total life cycle cost. Example

[0034] Please see Figure 1-3 An external threaded groove is provided on the outer circumferential wall of valve 200;

[0035] An adjusting gear 300 is installed on the outer circumferential wall of the valve 200. The adjusting gear 300 includes a tapered connecting ring 310 and a first gear 320.

[0036] The tapered connecting ring 310 is coaxially mounted on the bottom of the first gear 320, and the inner cavity of the tapered connecting ring 310 is in communication with the inner cavity of the first gear 320.

[0037] The inner wall taper of the tapered connecting ring 310 is the same as the outer wall taper of the valve 200. An internal thread 311 matching the external thread groove is provided on the inner wall of the tapered connecting ring 310. The tapered connecting ring 310 is screwed onto the outer wall of the valve 200.

[0038] The connection between the tapered connecting ring 310 and the first gear 320 protrudes inward and contacts the outer wall of the valve 200. By rotating the first gear 320, the tapered connecting ring 310 is driven to rotate. Through the threaded connection, the tapered connecting ring 310 moves along the axial direction of the valve 200 on the outer wall of the valve 200.

[0039] When the tapered connecting ring 310 moves toward the side with the larger outer diameter of the valve 200, the protruding part at the connection between the tapered connecting ring 310 and the first gear 320 squeezes the valve 200, and the valve 200 gradually closes.

[0040] When the conical connecting ring 310 moves toward the side with the smaller outer diameter of the valve 200, the protruding part at the connection between the conical connecting ring 310 and the first gear 320 gradually moves away from the outer wall of the valve 200, relieving the pressure on the valve 200, and the valve 200 gradually opens under its own elastic force.

[0041] The valve 200 is closed and opened by moving the conical connecting ring 310, and the degree of opening and closing of the valve 200 is adjusted. The periodic opening and closing action of the valve 200 can shear, squeeze and break up soft particles or polymers that are about to block, thus playing a self-cleaning role. The flow channel morphology changes during the opening and closing process of the valve structure, making it difficult to form a fixed dead corner for long-term deposition of solid materials. This greatly improves the distributor's ability to handle dirty, easily crystallized, and solid particle-containing materials, reduces the frequency of shutdown for cleaning, and increases the operating cycle.

[0042] When the liquid load is low and the flow rate is low, adjusting the opening can maintain a sufficient liquid seal, prevent gas from short-circuiting through the distribution hole, and avoid distribution failure. When the liquid load is high, adjusting the opening can ensure smooth liquid flow, prevent the liquid level in the distribution tank from overflowing due to excessively high liquid level, and avoid uneven distribution, thus greatly expanding the operational flexibility.

[0043] When the gas load increases, reducing the opening can decrease the liquid inflow and reduce the liquid holdup of the packing layer, thereby delaying or avoiding flooding. This allows the tower to operate stably under higher gas-liquid loads, tapping into the maximum potential processing capacity of the unit, effectively suppressing flooding, and improving processing capacity.

[0052] A guide 600 is mounted on the surface of the tray 100. The guide 600 is connected to the transmission component 400 and the drive component 500 respectively. The guide 600 includes a pressure plate 610, a connecting block 620 and a mounting plate 630.

[0053] The pressure plate 610 is a T-shaped plate. One end of the pressure plate 610 has an arc-shaped structure. The top of the pressure plate 610 near the arc end has a connecting hole 611 that matches the connecting shaft 520. The connecting hole 611 penetrates the bottom of the pressure plate 610.

[0054] The end of the connecting shaft 520 away from the slot 100 is connected to the connecting hole 611 via a bearing. A motor is installed on the top of the pressure plate 610. The motor is waterproofed. The output shaft of the motor is connected to the connecting shaft 520 via a spline or a flat key. The connecting shaft 520 drives the second gear 510 to rotate. The second gear 510 and the internal gear 430 work together to drive the moving block 410 to move horizontally on the slot 100.

[0055] The external gear 420 moves with the moving block 410 to drive the first gear 320 to rotate. The first gear 320 moves along the axial direction of the valve 200 on the outer side wall of the valve 200 through the thread to perform the closing and closing operation of the valve 200 and adjust the opening degree of the valve 200.

The moving block 410 is guided by the horizontal end of the pressure plate 610 and the mounting plate 630.
