Gravity settling chambers for controlling air pollution

May 18, 2016  Gravity settling chambers for controlling air pollution 1. Presented by Joy H Jones 2. Gravity settling chambers are the oldest and simplest means of removing suspended particles from a gas In principle,pollutants are removed by reducing the velocity of the gas stream sufficiently to allow particles to settle out under the influence of gravity The simplest chamber is merely a horizontal duct ...

VOC, PM Odor: Equipment - Gravity Settler

To separate smaller particles would require excessive horizontal flow distances, which would lead to excessive chamber volumes. It is an unsophisticated device that must be cleaned manually at regular intervals. Gravity settlers have little practical industrial use in pollution control because they are ineffective for small particles.

AIR POLLUTION CONTROL ENGINEERING

distance in a gravity settler is H (Fig. 9.1). The length of the flow path is Nlr Do, where N is the number of turns that the gas makes traversing the outer helix of the cyclone, before it enters the inner helix, and Do is the outer diameter of the cyclone. This length of the flow path corresponds to L in the gravity settler. Making these
