Waste Gases Cleaning at the Production of Ferrum Oxide Pigment Using Horizontal Apparatus with Bucket-like Dispersers
The efficiency of horizontal apparatus with bucket-like dispersers (HABD) for waste gases cleaning from Fe2O3 dust at the production of red ferrum oxide pigment has been proved by the experiments. It is advisable to carry out the dust trapping in HABD under countercurrent mode. Such mode allows to condense steam from the gas phase and trap small particles of the dust. The positive effect of surface active substances on the dust trapping has been shown. Technologically feasible concentrations of polyacrylamide have been determined.
