The utility model discloses an efficient desulfurization and dust removal device which comprises a desulfurization
tower main body, the
cyclone dust collector is mounted in the desulfurization
tower main body; the
rotational flow plate is mounted in the desulfurization
tower main body and is positioned at the top of the
cyclone dust collector; the spraying
assembly is fixedly connected to the interior of the desulfurization tower main body; the auxiliary mechanism is arranged at the side part of the desulfurizing tower main body and is used for forming an overhaul window so as to overhaul the spraying
assembly. The
cyclone dust collector, the
rotational flow plates, the spraying
assembly, the
demister and the auxiliary mechanism are matched with one another, large
dust particles are removed through
centrifugal force, then alkali liquor is violently stirred by high-speed
airflow through the three
layers of vortex
rotational flow plates, so that water reaches the optimal atomization quality, and the atomization effect is good. According to the
diesel exhaust gas desulfurization and dust removal device, dust in
flue gas and alkali liquor reach the maximum contact area, mist is removed through the
demister, the auxiliary mechanism provides a maintenance window for the spraying assembly, and then the
diesel exhaust gas desulfurization and dust removal effects are improved.
