Busch Purifier

Liquid Particulate Removal Unit

The Busch Purifier is a high velocity, inline cyclonic eliminator designed to collect liquid particulate from an airstream This device is the standard mist removal method for rolling mills in the metals industry, cleaning over 2.5 million scfm since first introduced in 1968.

The highly effective PURIFIER, which employs a two stage design is self-cleaning and has no moving parts. As the contaminated gas enters the unit and strikes an impingement head, larger particles are removed. The gas then passes through a vaned element which redirects the entrained liquid to the inside surface of the shell where it is collected and drained away. Specific application options such as sprays for element cleaning, shell and drain heat tracing and insulation may be added as required to improve operation and maintenance characteristics.

The PURIFIER handles coolant laden air at a constant pressure drop and is highly efficient in removing most liquid particulate 10 microns and larger in size.

The design of the PURIFIER is unique in comparison to other centrifugal mist eliminatorssince it has been specifically designed for rolling mill coolant removal applications. Several of the more recent modifications include relocation of drains to handle dirt contaminated coolants, redesign of drain troughs to a sloped configuration to enhance drainage of higher viscosity liquids, relocation of access doors to reduce re-entrainment and a reduction in thenumber of element supports to improve airflow characteristics.

Principal components of the PURIFIER include a vaned separating element of type 304stainless steel and a vessel shell of minimum 1/4î steel plate. Hinged access doors are provided in each compartment. These doors are equipped with cam-level fasteners and safety bolts to prevent accidental opening. Unit support legs are available.
