Suction and overflow combined type gas and liquid separator

Abstract

The invention relates to the technical field of hydrogenation reactor equipment of fixed beds, and discloses a suction and overflow combined type gas and liquid separator. The suction and overflow combined type gas and liquid separator comprises a bubble cap, an overflow pipe, a center pipe and a crushing plate, wherein the bubble cap, the overflow pipe, the center pipe and the crushing plate are coaxially connected; the bottom surfaces of the overflow pipe and the center pipe are flush with the lower surface of a tower tray plate; the crushing plate is connected with a bolt at the bottom part of the center pipe through a fastener; the top part of the overflow pipe is provided with an overflow port; a second positioning part is arranged at the lower part of the overflow pipe; the bottom surface of the second positioning part is in contact with the upper surface of the tower tray plate; a cover plate is arranged at the top part of the center pipe; the pipe wall, exposing out of the bubble cap, of the upper part of the center pipe is provided with a plurality of gas inlets, the middle part of the pipe wall of the center pipe is provided with a plurality of gas outlets, and the highest location of the corresponding gas outlet is lower than the bottom part of the overflow port. The suction and overflow combined type gas and liquid separator has the advantage that the gas and liquid separator and the tower tray plate form the gas and liquid distribution panel, and the gas and liquid phase raw materials are uniformly distributed to the catalyst bed layer, and are in full contact with the catalyst, so that the radial temperature difference of the catalyst bed layer is decreased, the oil quality is improved, and the production cost is saved.

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 ...
