Research for Measuring Concentration of Gas/Solid Two Phases Flow

摘要：

The measuring concentration of Gas/Solid two phases flow is a difficult question in industrial process. The paper introduced an experimental research method and a system for measuring concentration of gas/solid two phases flow based on electrical capacitance tomography. The ECT system was 8 internal electrodes and an ac-based low capacitance measuring circuit. Two flow patterns, i.e. full and half field distribution, and 4 types of concentrations were used to be reconstructed by ECT system. Therefore, the experimental resultants showed that the relationship between the concentration and the average of grey level value of reconstruction image or, normal measured capacitance are monotonous and nonlinear, that means the method of measuring concentration of gas/solid two phases flow is feasible. In addition, the resultants also showed that the ECT system is ability to detect the blocking state of the pipe.
