The invention relates to the technical field of fixed-bed hydrogenation reactor equipment, and discloses a combined suction and overflow gas-liquid distributor, which includes a coaxially connected bubble cap, an overflow pipe, a central pipe, a crushing plate, and an overflow pipe , The bottom surface of the central tube is flush with the lower surface of the tray plate, the crushing plate is connected with the bolts at the bottom of the central tube through fasteners, the top of the overflow pipe is provided with an overflow port, and the bottom of the overflow pipe is provided with a Two positioning parts, the bottom surface of the second positioning part is in contact with the upper surface of the tray plate; the top of the central tube is provided with a cover plate, and the upper part of the central tube exposed to the outside of the bubble cap is provided with several air inlets on the tube wall, and the central tube The middle part of the pipe wall is provided with several air outlets, and the highest position of the air outlets is lower than the bottom of the overflow port. The invention is assembled with the tray plate into a gas-liquid distribution plate, which evenly distributes the gas-liquid phase raw materials to the catalyst bed, making it fully contact with the catalyst, so as to reduce the radial temperature difference of the catalyst bed, thereby improving the quality of oil products, reduce manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of fixed bed hydrogenation reactor equipment, in particular to a suction overflow combined gas-liquid distributor. Background technique [0002] The hydrogenation unit is an important equipment for the production of clean fuel oil. With the increasingly stringent global environmental protection regulations, the pace of upgrading the quality of oil products in various countries is also gradually accelerating, which puts forward higher requirements for the product quality of the hydrogenation reactor. The optimal design of hydrogenation reactor internals has become an important factor restricting the further development of hydrogenation technology. The stable progress of the hydrogenation reaction, the full function of the hydrogenation catalyst, and the quality of the product meeting the high-quality technical requirements largely depend on the uniformity of the distribution of the gas-liquid two-phase fluid ...
