Environmental-friendly gas-solid fluidized bed teaching experiment device

Abstract

The invention provides an environmental-friendly gas-solid fluidized bed teaching experiment device, which consists of a fluidized experiment system and a computer aided system. In the system, a gas compressor conveys the gas into a gas buffer tank in a pressurized way; after the buffering, the pressure intensity and the temperature are measured; then, after passing through a filling material filling layer and a gas distribution plate, the gas enters a fluidized bed layer, and drives a quartz sand bed layer to be in a fluidized state; the top of the fluidized bed is sealed; through a lateral side outlet, the gas is introduced into a liquid sealing device; measuring points with different heights are arranged at the bottom of the fluidized bed in the axial direction for measuring the bed layer porosity and the particle hour average speed; relevant data is collected and recorded by computers. On the basis of ensuring the stable operation and the accurate measurement of the performance parameter of the fluidized bed, the teaching quality and the experiment safety are obviously improved; the experiment teaching environment is improved.

Description

technical field [0001] The invention relates to an environment-friendly gas-solid fluidized bed device, in particular to a gas-solid fluidized bed device used for the teaching of experimental courses in colleges and universities and the experimental research of research institutes. [0002] technical background [0003] The fluidized bed suspends a large number of solid particles in the moving fluid, so that the particles have some apparent characteristics of the fluid. In the industrial fluidized bed reactor, the granular material can continuously enter and exit the reactor like a fluid. It is beneficial to the mass transfer, heat transfer and gas-solid phase reaction process between materials. It has been widely used because of the uniform bed temperature and concentration. Due to the key position of the fluidized bed in industrial production, in the experimental teaching, the gas-solid flow The hydrodynamic measurement experiment of the chemical bed is an important part of...

AI Technical Summary

Problems solved by technology

The fluid pipeline design of the fluidized bed used in the teaching of most colleges and universities is unreasonable, and the temperature cannot be measured in real time. Not only is it difficult to accurately obtain and post-process the experimental data, but the experimental results have large errors. The concentration of .5 increases obviously, and with the generation of oil mist, it causes laboratory environment and safety problems, and affects health. At the same time, the computer-aided system is used to evaluate the bed performance parameters, which can lay a good foundation for university laboratories and industrial promotion.
