Microwave field and electromagnetic field coupled thermal state gas-liquid-solid reaction apparatus

Abstract

The invention discloses a microwave field and electromagnetic field coupled thermal state gas-liquid-solid reaction apparatus. The apparatus comprises a three-phase reaction bed, disturbance heat particles, a fluidizing gas distribution device, a liquid phase injection device, a microwave field emission device and an electromagnetic field generation device. The apparatus simultaneously couples a microwave field with an electromagnetic field on the basis of an airflow field and a gravitation field, makes partial particles in the bed move and be heated in the multi-field, optimizes the heating mode and the current sharing mode of a traditional reactor, and realizes the heating function in the current sharing process, so the apparatus has multiple functions; the coupling of the electromagnetic field on the basis of the airflow field reinforces the disturbance in the bed, increases the gas-liquid-solid contact surface, and is in favor of the smooth implementation of a reaction; the superpose of the microwave field on the electric magnetic field obviously improves the heating efficiency and the heating rate of a reactor; and the microwave heating and the magnetic motion of particles are realized through heavy disturbance heat particles and lightweight disturbance heat particles.

Description

technical field [0001] The invention belongs to the technical field of multiphase flow involved in the biomass thermochemical conversion process, and particularly relates to a thermal gas-liquid-solid three-phase reaction device in which a microwave field and an electromagnetic field are coupled with each other. Background technique [0002] The gas-liquid-solid three-phase reaction device is a kind of multiphase physical operation device or chemical and biological reactor with important industrial application value. The gas-liquid-solid three-phase reaction device is composed of three phases of gas phase, liquid phase and solid phase, wherein the liquid phase is a continuous phase, the gas phase is a discrete phase, and the solid particles are suspended in the gas phase and the liquid phase. When the gas-liquid-solid three-phase reaction device is used as a chemical reactor, whether the gas phase is used as an inert gas or the solid phase is used as a catalyst, the disturba...
