Filter device for removing particulate material from gases
Particle-laden gas passes downwardly through an inlet duct into inlets of several wedge-shaped deceleration chambers formed by vertical plates radiating from a central region below the bottom of the inlet duct. The inner ends of the plates and the inlet of the chambers are vertically below the bottom of the inlet duct. In each chamber the gas first proceeds towards a particle exit at the bottom of the chamber, then reverses direction and passes upwardly into filter units above wider parts of the chamber, depositing some heavy particles near the particle exit. To purge the chambers and filter units, a suction device is connected to an outlet duct and one or more inlets to the chambers are closed off from the inlet duct simultaneously with the particle exit(s) of the same chamber(s) being connected to the outlet duct.
