Abstract

The invention provides a gas-solid multiphase flow online measurement device and method based on arc-shaped electrostatic electrode arrays in the field of industrial gas-solid multiphase flow tests. The measurement device comprises the arc-shaped electrostatic electrode arrays, a first metal electrode set and a second metal electrode set are sequentially arranged in the inner circumferential face of each arc-shaped electrostatic electrode array side by side, first metal electrodes and second metal electrodes are each in the shape of an arc, and the axial width of each first metal electrode is smaller than that of each second metal electrode. The invention further relates to the measurement method based on the measurement device. According to the method, the speed and the flowing stability of solid phase powder are measured through the high sensitivity of the first metal electrodes and the bandwidth, and the solid phase power mass flow rate is measured through the large sensitive areas of the second metal electrodes and the space filtering effect. The device and method have the advantages that on-site implementation is convenient, measurement is accurate and reliable, the measurable range is large, the using time is long, and maintenance is convenient, and the device and method can be widely applied to continuous online monitoring of industrial pneumatic solid phase powder conveying.

Description

[0001] Technical field [0002] The invention belongs to the technical scope of gas-solid two-phase flow testing, and in particular relates to an online measurement device and method for gas-solid multiphase flow based on an arc-shaped electrostatic electrode array. Background technique [0003] Gas-solid multiphase flow widely exists in important industrial production processes such as pneumatic conveying pipelines, solid-solid fluidized beds, and exhaust emissions. The movement of solid phase powder driven by flowing gas is of great significance to optimize the production process, improve production efficiency and ensure safe production. Traditional single-phase fluid measurement methods based on stress and throttling methods are not suitable for the measurement of industrial gas-solid two-phase or multiphase flow. Capacitance, optics, radiation, heat conduction, digital imaging and acoustic technologies are easily affected by the properties of solid phase powder and env...
