Abstract
Systems and methods for separating contaminants in a contaminated airstream are described. In one embodiment, a contaminated airstream is received and a vortex is created that separates the contaminated airstream into a clean airstream used in the system and contaminants (e.g., debris and particles).
Claims20
A contaminant separator comprising:
- a separator enclosure;
- an airflow inlet tangential to the separator enclosure that receives contaminated air flow;
- a spiral plate having a sloped section and a horizontal flat section in the separator enclosure that creates a vortex of the contaminated air flow, and separates contaminants from clean air;
- and
- an outlet that egresses clean air flow.
2 more elements
A system comprising:
- a cyclone separator that separates liquid or debris from a main airstream and generates a clean air stream by creating a vortex in the cyclone separator, the cyclone separator includes:
- a separator enclosure that comprises a cylindrical upper housing section and a conical lower housing section;
- a tangential inlet on the cylindrical upper housing section that channels the main air stream to the separator enclosure;
- a weep hole that egresses the liquid or the debris, and
- a spiral plate enclosed in the separator enclosure that creates the vortex, the spiral plate including a sloped section and a horizontal flat section;
- an electro-pneumatic controller the receives the clean air stream;
- and
- a valve that is controlled by the electro-pneumatic controller, that releases air to an engine.
5 more elements
A method of separating contaminants comprising:
- receiving a contaminated airstream through a tangential inlet;
- creating a vortex from the contaminated airstream using a spiral plate having a sloped section and a horizontal flat section, wherein the vortex creates a downward flow and an upward flow;
- separating a clean airstream from contaminants in the vortex, wherein the clean airstream is in the upward flow;
- and
- outputting the clean airstream.
