AI Technical Summary

Technical Problem

Existing silane fluidized bed reactors suffer from deposition and agglomeration issues and uneven radial temperature distribution during temperature measurement, which affect the stable operation of the fluidized bed reactor.

Method used

A temperature-measuring gas distributor was designed, comprising a nozzle, a thermometer, a sleeve, and aerogel. The outer surface of the nozzle is covered with a protective coating, the thermometer is filled with aerogel, and the sleeve fits tightly against the thermometer to prevent reactant agglomeration and isolate airflow interference, thus ensuring the accuracy of temperature measurement.

Benefits of technology

It enables accurate measurement of the internal temperature of the fluidized bed reactor, avoids agglomeration and contamination, ensures the heat transfer efficiency and temperature measurement stability of the temperature measuring device, and provides reliable temperature data to support the regulation of the fluidized bed reactor.
