Technical Field

The utility model relates to the technical field of flue gas dust removal, in particular to a high-efficiency multi-stage wet dust removal device.

Background Art

The emission of large amounts of smoke and dust will cause serious pollution to the environment. Wet dust removal devices are often used in industrial production. Wet dust removal devices use the inertial collision and mixing effects of water droplets and smoke to allow the smoke and dust particles to be carried away by the water flow, thereby achieving the purpose of dust removal.

During use, the existing wet dust removal device is generally only equipped with a spraying area to spray dust on the flue gas, the dust removal efficiency is low, and the water resources cannot be reused, resulting in a waste of water resources. Therefore, we have introduced a new high-efficiency multi-stage wet dust removal device.
