Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a high-efficiency fluid distributor for a petrochemical packed tower. Background Art

[0002] In petrochemical production, packed towers are often required for gas-liquid two-phase contact reactions. To ensure sufficient contact between the liquid phase and the gas phase, a fluid distributor is required to disperse and evenly distribute the liquid phase. There are many types of fluid distributors, but multi-trough fluid distributors can be disadvantageous in that, when dispersing fluid materials, if coking occurs during the reaction, the fluid will deposit at the bottom of the trough, clogging the diversion holes and leading to uneven diversion. This in turn prevents the fluid from being distributed effectively, resulting in a poor distribution. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a petrochemical packing tower high-efficiency fluid distributor, which is used to solve the problem that the existing multi-trough fluid distributor is prone to clogging the diversion holes and causing uneven diversion when coking occurs during the reaction process.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A high-efficiency fluid distributor for a petrochemical packed tower, comprising a primary diverter trough, a secondary diverter trough, and a tertiary diverter trough. The primary diverter trough is located above the interior of the secondary diverter trough. There are multiple tertiary diverter troughs, all located below the secondary diverter trough and perpendicular to the arrangement direction of the secondary diverter trough. Diverter holes are equidistantly arranged on the bottom of the inner walls of the primary diverter trough, the secondary diverter trough, and the tertiary diverter trough along the axial direction.

[0006] Support rods are installed inside the secondary diversion trough and the tertiary diversion trough, and a feeding rope is hung on the support rod. The lower end of the feeding rope passes through the diversion hole and is hung with a feeding plate, and a connecting rope in contact with the bottom of the inner wall of the secondary diversion trough and the tertiary diversion trough is connected between two adjacent feeding ropes.

[0007] Preferably, the bottoms of the secondary diverter trough and the tertiary diverter trough are both multi-V-shaped structures, and the diverter hole is located at the lowest point of the multi-V-shaped structure.

[0008] Preferably, the connecting rope is arranged along the lowest point of the multi-V-shaped structure at the bottom of the inner wall of the secondary diversion trough and the tertiary diversion trough.

[0009] Preferably, the heights of both ends of the connecting rope are higher than the bottom heights of the inner walls of the secondary diverter groove and the tertiary diverter groove, and the bottoms of the inner walls of the secondary diverter groove and the tertiary diverter groove are in contact with the middle of the connecting rope respectively.

[0010] Preferably, the feeding disk is a conical disk with notches symmetrically arranged on the circumference.

[0011] Preferably, both ends of the inner walls of the secondary diverter trough and the tertiary diverter trough are provided with clamping grooves, and the secondary diverter trough and the tertiary diverter trough are respectively equipped with support rods through the clamping grooves.

[0012] Preferably, the material-beating rope and the connecting rope are both thin chains.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model provides a material-beating rope in the diversion hole. When the fluid material is poured downward, it will impact the material-beating plate and drive the material-beating rope to swing and continuously stir in the diversion hole, effectively avoiding the problem of material coking and clogging the diversion hole, and preventing uneven diversion. It solves the problem of the existing multi-trough fluid distributor that the diversion hole is easily blocked when coking occurs during the reaction process, resulting in uneven diversion.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-7 As shown, the utility model provides a technical solution: a petrochemical packed tower high-efficiency fluid distributor, comprising a primary diverter trough 1, a secondary diverter trough 2 and a tertiary diverter trough 3, wherein the primary diverter trough 1 is located above the interior of the secondary diverter trough 2, and there are multiple tertiary diverter troughs 3, all of which are located below the secondary diverter trough 2 and perpendicular to the setting direction of the secondary diverter trough 2. The bottoms of the secondary diverter trough 2 and the tertiary diverter trough 3 are both multi-V-shaped structures, and the diverter hole 4 is located at the lowest point of the multi-V-shaped structure. The bottoms of the inner walls of the primary diverter trough 1, the secondary diverter trough 2 and the tertiary diverter trough 3 are all equidistantly provided with diverter holes 4 along the axial direction.

[0026] Support rods 5 are installed inside the secondary diverter trough 2 and the tertiary diverter trough 3. Both ends of the inner walls of the secondary diverter trough 2 and the tertiary diverter trough 3 are provided with clamping grooves 9. The secondary diverter trough 2 and the tertiary diverter trough 3 are respectively installed with support rods 5 through the clamping grooves 9. A feeding rope 6 is hung on the support rod 5. The lower end of the feeding rope 6 passes through the diverter hole 4 and is hung with a feeding tray 7. The feeding tray 7 is a conical tray with notches symmetrically arranged on the circumference;

[0027] A connecting rope 8 in contact with the bottom of the inner wall of the secondary diverter trough 2 and the tertiary diverter trough 3 is connected between two adjacent feeding ropes 6. The feeding rope 6 and the connecting rope 8 are both thin chains. The connecting rope 8 is set along the lowest point of the multi-V-shaped structure at the bottom of the inner wall of the secondary diverter trough 2 and the tertiary diverter trough 3. The heights of both ends of the connecting rope 8 are higher than the height of the bottom of the inner wall of the secondary diverter trough 2 and the tertiary diverter trough 3, and the bottom of the inner wall of the secondary diverter trough 2 and the tertiary diverter trough 3 are respectively in contact with the middle of the connecting rope 8.

[0028] Working principle:

[0029] The fluid material is transported to the primary diverter trough 1 through a pipeline, and the fluid material flows in the primary diverter trough 1 to the secondary diverter trough 2, and flows to the tertiary diverter trough 3 or is directly sprinkled downward through the diverter hole 4. The fluid material in the secondary diverter trough 2 is eventually sprinkled downward through the diverter hole 4. When the fluid material is sprinkled downward, it will impact the feeding plate 7, driving the feeding rope 6 to swing and continuously stir in the diverter hole 4, effectively avoiding the problem of material coking and blocking the diverter hole 4, and preventing the problem of uneven diversion. Since the diverter hole 4 is set at the lowest point of the multi-V-shaped structure at the bottom of the secondary diverter trough 2 and the tertiary diverter trough 3, the connecting rope 8 set between adjacent feeding ropes 6 will swing when the feeding rope 6 swings and the fluid material flows, which can prevent the coked material from being deposited at the bottom of the secondary diverter trough 2 and the tertiary diverter trough 3, without manual cleaning, which is convenient for use and maintenance.
