Abstract

The invention belongs to the field of chemical engineering, and in particular relates to a device for measuring the residence time distribution of gas-liquid cyclone liquid phase. The liquid phase storage tank is connected to the inlet of the cyclone separator through the liquid phase feed pipeline, and the liquid phase feed pipeline is equipped with a liquid phase feed pump, a liquid phase flow meter, and a liquid phase feed valve; the inlet of the cyclone separator At the same time, the tracer injection port is connected, and the liquid discharge port at the bottom of the cyclone separator is connected to the fan through the liquid discharge pipeline. The liquid discharge pipeline is equipped with a rectifier element, a conductivity probe, a liquid discharge separation tank, a liquid discharge branch gas phase flowmeter, Liquid discharge branch valve; the exhaust port on the top of the cyclone separator is connected to the fan through the exhaust pipeline, and the exhaust branch flowmeter and exhaust branch valve are installed on the exhaust pipeline; the conductivity probe is connected to the conductivity meter, and the conductivity meter Connect to a computer for data recording to obtain the liquid phase residence time distribution. The device can measure the residence time distribution of the liquid phase under the condition of the gas-liquid swirling flow, and overcomes the defect that the conventional measurement method cannot be used for dispersing the liquid phase.

Description

technical field [0001] The invention belongs to the field of chemical engineering, and in particular relates to a device and method for measuring the residence time distribution of a gas-liquid swirl liquid phase, which is used for measuring the residence time distribution of a liquid phase under the condition of a gas-liquid swirl flow, and overcomes the limitations of conventional residence time measurement methods limitation. Background technique [0002] The residence time distribution is an important parameter to study the performance of reactors or separation equipment. The residence time distribution can reflect the mixing state of fluids in the reaction or separation equipment, and is an indispensable theoretical basis for the optimal design and operation of such equipment. The determination of residence time distribution is not only widely used in chemical reaction engineering and chemical separation process, but also in other fields of designing flow process. [0...
