Deposition Thickness Detection Method based on Dust Distribution Law of Ventilation Dust Removal Pipeline

Aiming at the status of the measurement of the deposition dust thickness of ventilation and dust collection pipes in industrial workplaces in China, the law of dust distribution in ventilation and dust collection pipelines was studied by numerical simulation method. A high-precision dust deposition thickness detection method was studied. For this reason, based on the gas-dust flow characteristics in the ventilation and dust removal pipelines, based on the SIMPLE algorithm of the same-location grid, the dust distribution law of the ventilation and dust removal pipelines was numerically simulated using Fluent; then the dust deposition quality-thickness relationship was derived using the simulation results. The expression, which converts quality inspection into thickness inspection, completes this detection method. Experiments show that: the thickness of the detection of the resolution of 0.01mm and the accuracy of 0.07mm achieved good detection results.
