Mosquito coil type heterogeneous reactor and mosquito coil type heterogeneous reactor group

Abstract

A mosquito coil type heterogeneous reactor includes a cavity, the top of the cavity is provided with a liquid phase medium inlet, the bottom of the cavity is provided with a liquid phase medium outlet, the upper part of the sidewall of the cavity is provided with a gas phase medium outlet, and the lower part of the sidewall of the cavity is provided with a gas phase medium inlet; a first mosquitocoil type liquid distributor group, a first catalyst layer, a second mosquito coil type liquid distributor group, a second catalyst layer and a gas phase medium distributor are sequentially arranged in the cavity at intervals from top to bottom; the liquid phase medium inlet is communicated with a six-way joint, four inverted L-shaped liquid phase medium distribution tubes are evenly distributed on the peripheral surface of the six-way joint and communicate with the six-way joint, the lower bottom surface of the six-way joint is communicated with a vertical liquid phase medium distribution tube, and the liquid medium distribution tube passes through the first mosquito coil type liquid distributor group, the first catalyst layer, the second mosquito coil type liquid distributor group and the second catalyst layer from top to bottom, and extends into the lower part of the cavity; and the tube wall of every liquid phase medium distribution tube is provided with a plurality of through holes for mounting atomizers. The mosquito coil type heterogeneous reactor increases the contact area of the gas-liquid phase medium and increase the gas-liquid phase mass transfer speed.

Description

technical field [0001] The invention relates to a heterogeneous reactor, more specifically, to a mosquito-repellent coil heterogeneous reactor and a group of mosquito-repellent coil heterogeneous reactors. Background technique [0002] Various types of heterogeneous reactors are widely used in industrial applications. Such as hydrogenation, halogenation, sulfonation, nitration, oxidation of organic and inorganic compounds, etc. Heterogeneous reactors consist of gas, liquid or solid mixtures and are ubiquitous in modern industry. Gas-liquid phase reactions are also an important class of heterogeneous reactions involving mass transfer between phases. [0003] The gas-liquid reactors widely used at home and abroad now add regular or irregular fillers to the inner chamber of the reactor, or add baffles or baffles to increase the degree of turbulence of the medium in the reaction chamber, so as to achieve Enhance fluid mixing. However, simple baffles or fillers cannot satisfy...

AI Technical Summary

Problems solved by technology

However, simple baffles or fillers cannot satisfy the swirling flow of the medium in a narrow and confined space, and cannot maximize the realization of gas-liquid contact, which affects the mass transfer between the reaction phases.
