Abstract

The invention discloses a quench mixer used for a hydrogenation reactor and aims to solve problems that a mixing effect is poor and a flow resistance of a mixed material flow is large when a quench mixer in the prior art is used for mixing and distributing a mixed material flow having a large amount of gas-phase reactants. The quench mixer is provided with a plurality of rotational-flow plates (5), wherein tops of the rotational-flow plates (5) are connected to a top baffle (2) and bottoms of the rotational-flow plates (5) are connected to a shutoff plate (4). A central hole (40) is formed in the center of the shutoff plate (4). A distribution plate (6) is arranged under the central hole. At least four arc-shaped plates (3) are disposed between the top baffle and the shutoff plate, around an edge of the top baffle and at external ends of the rotational-flow plates. A mixed material flow inlet (30) is arranged between each two adjacent arc-shaped plates. Each rotational-flow plate is arranged at a position corresponding to each mixed material flow inlet. A top baffle folded-edge (21) is disposed at the periphery of the top baffle. A distribution plate folded-edge (61) is disposed at the periphery of the distribution baffle. The quench mixer is mainly used in the hydrogenation reactor used for processing light-weight oil.

Description

technical field [0001] The invention relates to a quenching mixer used for a hydrogenation reactor in petroleum refining and petrochemical industry, which belongs to the internal component of the hydrogenation reactor. Background technique [0002] In petroleum refining and petrochemical industry, hydrogenation reaction is very common and widely used, such as hydrocracking and hydrofining. The hydrogenation reaction is an exothermic reaction, and the temperature of the reactants needs to be controlled during the reaction to prevent the catalyst bed temperature from rising rapidly and causing the activity of the catalyst to decrease. In industrial design, the catalyst in the fixed-bed hydrogenation reactor is usually divided into multiple beds, and cold hydrogen is added between two adjacent beds. hydrogen. The quench mixer is a place for mixing hot reactants and cold hydrogen and exchanging heat, and is an important internal component of the hydrogenation reactor. Quenchi...
