What are the dust removal methods for triple-cylinder dryers?

Cyclone dust removal

Driven by a fan, the dust-laden airflow enters the volute of the dust remover at a high speed in a tangential direction through the inlet and moves in a spiral rotation from top to bottom. Under the action of centrifugal force, the clean air rotates spirally from bottom to top along the axis and is discharged through the core pipe. Dust particles on the outer wall fall into the ash hopper along the wall under the drive of gravity and the downward-moving airflow, thus achieving the purpose of dust removal.

Bag dust removal

This equipment is controlled by a microcomputer, featuring compartmental reverse blowing and timed ash cleaning. It is also equipped with a temperature detection and display device as well as an over-temperature alarm device. Adopting CW300-FcA anti-condensation glass fiber filter bags, it can effectively prevent the condensation of filter bags and avoid filter bag burnout.

High-voltage electrostatic dust removal

The high-voltage electrostatic dust removal technology converts 50Hz, 220V alternating current into direct current of more than 100kW and applies it to the corona electrode (cathode) to form an uneven high-voltage electric field, which ionizes the gas to generate a large number of negative ions and electrons, thereby charging the dust particles in the gas entering the electric field. Under the action of the electric field force, the charged dust particles move toward the opposite electrode (the anode is generally the dust collection electrode), fall into the ash hopper by rapping and are discharged, completing the process of purification and dust removal.
