A liquid impinging-stream reactor

Abstract

An impinging-stream reactor used for liquid-liquid mixing is disclosed. The reactor comprises a reactor shell and draft tubes. The reactor shell comprises a cylinder and heads. Centers of the outsides of walls of two ends of the reactor shell are provided with two perpendicular opposite feeding pipes. The first draft tubes are formed through two circular truncated cone shells disposed in an opposite manner, axes of the shells and the reactor coincide, and a thicker end of each of the draft tubes is connected to the corresponding feeding pipe; the second draft tube is disposed outside the first draft tubes, is cylindric, and is connected to the heads or the first draft tubes, and the axis of the second draft tube and the axis of the reactor coincide; and so on, the reactor can include a plurality of groups of draft tubes. The reactor achieves a plurality of times of liquid impinging, provides sufficient residence time for materials, achieves stepped reactions, reaches the target conversion ratio through designing flowing paths and a liquid flow rate, and overcomes the disadvantage that an impinging-stream reactor at present cannot achieve a high conversion ration through a single reactor.

Description

technical field [0001] The invention relates to a reactor used in the field of petroleum and chemical production, in particular to an impingement flow reactor used for liquid-liquid reaction. Background technique [0002] In petroleum and chemical production, many processes are carried out in the liquid phase or in the phase state with the liquid as the continuous phase, and most of these processes also involve chemical reactions. Since the liquid belongs to the condensed matter system, molecular motion is greatly restricted. For processes that take place at the molecular scale, the microscopic mixing regime becomes very important. [0003] Impinging streams are a very effective method of achieving rapid mixing. It uses two high-speed fluids to collide with each other to form a highly turbulent impact zone in the reactor, which can effectively reduce the external resistance during the transfer process, promote mixing, and enhance mass and heat transfer. Impinging flow rea...
