Abstract

The invention relates to the technical field of fixed-bed hydrogenation reactor equipment, and discloses a suction overflow type gas-liquid distributor, which includes elbows and flow breakers installed on both sides of the opening of the tray plate through fasteners , the length of the inlet section of the elbow is less than the length of the outlet section, and there are several slits evenly distributed on the bottom of the inlet section, and several air inlet holes are arranged on the side wall of the outlet section away from the inlet section, and the lowest position of the air inlet hole is higher than the slits The highest position, the elbow is fixed above the opening of the tray plate through the first flange installed at the bottom of the outlet section; the outlet section of the elbow, the opening of the tray plate and the flow breaker are coaxially arranged; the flow breaker It includes several broken flow plates arranged in a three-dimensional spiral shape. The invention has the advantages of good distribution performance, small pressure drop, large fouling space, strong anti-tray tilting ability, large operating flexibility, wide application range, simple structure, convenient manufacture, easy installation, firmness and stability, etc., and can be used to a certain extent Extend the operating cycle of the reactor.

Description

technical field [0001] The invention relates to the technical field of fixed-bed hydrogenation reactor equipment, in particular to a suction overflow gas-liquid distributor capable of uniformly distributing gas-liquid two-phase fluid. Background technique [0002] The hydrogenation reactor is an important equipment for the refining and upgrading of petroleum products, heavy oil processing, residual oil treatment, and the production of efficient and clean energy. With the increasingly stringent global environmental protection regulations, the pace of upgrading the quality of oil products in various countries is also gradually accelerating, and higher requirements are put forward for the product quality of hydrogenation reactors. The uniformity of fluid distribution in the hydrogenation reactor directly affects the contact time between the reactants and the catalyst and the wetting degree of the catalyst surface liquid, which ultimately affects the distribution of the bed temp...
