Suction overflow type gas-liquid distributor

Abstract

The invention relates to the technical field of fixed bed hydrogenation reactor devices, and discloses a suction overflow type gas-liquid distributor. The gas-liquid distributor comprises an elbow pipe and a blowgun which are installed on the two sides of an opening of a deck through fasteners. The length of the inlet section of the elbow pipe is smaller than that of the outlet section, a plurality of slots are evenly distributed in the bottom of the inlet section, a plurality of gas inlets are formed in the side wall, away from the inlet section, of the outlet section, the lowest position of the gas inlets is higher than the highest position of the slots, and the elbow pipe is fixed to the upper portion of the opening of the deck through a first flange at the bottom of the outlet section. The outlet section of the elbow pipe, the opening of the deck and the blowgun are coaxially arranged. The blowgun comprises a plurality of stream breakers which are spirally distributed in a three-dimensional mode. The gas-liquid distributor is good in distribution performance, small in pressure drop, large in scale containing space, strong in tray inclination resistance, large in operation elasticity, wide in use range, simple in structure, convenient to manufacture, easy to install, firm and stable and the like, and the operation cycle of a reactor can be prolonged to a certain extent.

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...
