Design of Dust Contents Online Detector Based on Charge Induction Principle

The measurement of dust contents belongs to gas-solid two-phase flow field.It is a difficult measurement field due to the inherent complexity of multiphase flow and poor charge detection sensitivity.This paper designs a new online detection instrument of the dust content.The instrument utilizes the charge induction of particles flow to detect the dust content,and achieves the purpose of real-time online detection through the transmission of the signal.It can be widely used in dust contents detection of industrial exhaust gas.The use of charge induction technology to measure the dust contents completely solves the difficult issues such as low accuracy,poor time-effect and difficult to maintain,etc.
