Abstract
The existing equipment for measuring dust concentration has the problem of imprecise measurement of low concentration and small particle size dust. In this paper, the measuring device is optimized to solve this problem, and the spiral channel is added to the existing vertical pipe dust concentration measuring device, which makes the dust rotate in the pipeline. As a result, the velocity of the dust particles and the friction between the dust particles and the pipe wall are increased. A three-dimensional model is established in Gambit2.4, and the gas-solid two-phase flow is simulated by Fluent6.3. The velocity distribution cloud and pressure distribution cloud of dust were obtained. Through the comparison and analysis of the experimental data, the optimized measuring devices are as follows: The effect can improve the pressure difference and velocity of dust particles in the pipeline, so that the amount of induced charge measured by electrostatic sensor is greatly increased, so the accuracy of measuring low concentration and small particle size dust is improved.
