The desulfurization and dust collector is a desulfurization equipment for turbocharging turbulent dust removal and desulfurization technology. Its working principle is that sulfur-containing gas, under the action of a turbocharging turbulence device, rotates and diffuses at high speed to form enhanced turbulent mass transfer with the absorbing slurry. The process of mass transfer is to form an emulsion layer between gas and liquid, which not only accelerates chemical absorption and neutralization, but also keeps the liquid film close to neutrality, maintaining a stable mass transfer rate throughout the entire process. Therefore, it is a low resistance desulfurization equipment.
