Abstract

The invention discloses a multi-phase pipe type cyclone reactor. The multi-phase pipe type cyclone reactor comprises a flow speed regulation cyclone device, a gas-phase injector, a reaction pipe and a discharging control valve, wherein the flow speed regulation cyclone device is composed of a feeding pipe, a cyclone pipe, a cyclone tangential slit, a flow speed regulation valve and an outer jacket. A liquid phase enters the flow speed regulation cyclone device from the feeding pipe; axial flowing is changed into cyclone flowing and rotary and axial common flowing is formed in the cyclone reaction pipe; a cyclone flow speed of the liquid phase is regulated by conveniently and accurately regulating the size of an inlet of the cyclone tangential slit through the flow speed regulation valve, and the mixing strength of different reaction systems and the retention time in reaction pipe systems are realized; the multi-phase pipe type cyclone reactor disclosed by the invention is simple in structure, less in investment, convenient to operate and strong in adaptive capacity and is suitable for industries including metallurgy, chemical industry, materials, sewage treatment, medicines and the like.

Description

technical field [0001] The invention relates to a multiphase tubular swirl reactor, in particular to a multiphase tubular swirl reactor capable of accurately adjusting and controlling the liquid phase swirl velocity. Background technique [0002] For a multiphase reaction system in a tubular or plug flow reactor, theoretically speaking, the physical and chemical reaction process is mainly determined by the probability of collision or contact between the reaction substances that occur due to factors such as Brownian motion or gravity. . Therefore, in some cases, the kinetics of the reaction process is slow, the production efficiency is low, the equipment is large or the reaction tube is long, resulting in high material and processing costs for the equipment. In order to increase the reaction speed or increase the production efficiency and optimize the reaction conditions, it is necessary to optimize or strengthen the mixing degree of the liquid phase (homogeneous or heteroge...

Problems solved by technology

Therefore, in some cases, the kinetics of the reaction process is slow, the production efficiency is low, the equipment is large or the reaction tube is long, resulting in high material and processing costs for the equipment.

In order to increase the reaction speed or increase the production efficiency and optimize the reaction conditions, it is necessary to optimize or strengthen the mixing degree of the liquid phase (homogeneous or heterogeneous phase). The traditional method is to install mechanical stirring or install fins or baffles on the tube wall. Realized, but the former increases equipment investment and operating costs, and the mixing intensity of the latter is not easy to adjust and predict.
