Problems solved by technology
[0006] The weakening of the central confluence phenomenon, the improvement of droplet atomization performance and the improvement of gas-liquid mixing efficiency are the main improvement directions of the suction-type gas-liquid distributor. At present, the main means of improvement is to slot in specific positions of the cap and downcomer Or opening holes, or by adding additional components, these additional small components are easy to foul or wear, difficult to install and disassemble, and increase the pressure drop

The invention discloses a downcomer and a suction type, overflow type and mixed type gas-liquid distributor. The two ends of the downcomer are open, and the side wall of the downcomer is an inwardly concave arc, and the diameter of the two ends is larger than the diameter of the middle part; A broken liquid hole is arranged on the plate, and the broken liquid plate is connected with the side wall of the downcomer through the first connecting rod. The suction type gas-liquid distributor includes the above-mentioned downcomer and a cap arranged above the downcomer. The cap includes a top wall of the cap and a side wall of the cap. The bottom end of the side wall of the cap is provided with a Extended bar seams. The overflow type gas-liquid distributor includes the above-mentioned downcomer, and an overflow hole is opened on the downcomer. The hybrid gas-liquid distributor includes the above-mentioned downcomer and a cap covering the downcomer, and an overflow hole is set on the downcomer. The invention provides a downcomer, a suction type, an overflow type and a mixed type gas-liquid distributor which can improve and stabilize the gas-liquid two-phase distribution so that it can evenly enter the bed.
Description
technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a downcomer and a suction type, overflow type, and hybrid gas-liquid distributor. Background technique [0002] The uniform distribution of gas-liquid two-phase flow in the bed is an important indicator of the packed bed reactor, which directly affects the wetting of the catalyst, the contact time of the reactants, whether there will be bias flow, short circuit and local hot spots in the packed bed, and finally It affects the life of the catalyst, the operating cycle of the device and the quality of the product. Whether the gas-liquid distribution in the packed bed is even or not largely depends on the gas-liquid distributor, especially in some large-scale and high-precision reactors, the importance of gas-liquid distribution is becoming more and more prominent. . [0003] The gas-liquid distributor is an internal component used in a packed bed reactor. Its function ...
