Abstract
A fume evacuation system is designed to remove smoke, fumes, and particulate from a metal-working or other application. The system may include a cart-type base unit or may be incorporated into a fixed or semi-fixed installation that uses suction to draw air (e.g., containing smoke, fumes, and particulate) away from the metal-working application. The fume evacuation system includes a hood that creates an arduous flow path and varying velocity profile, which cools and separates any particulate matter in the suctioned air. The arduous flow path may include multiple sharp turns created by an inner deflector component and an inlet tube. The inlet tube may further contain baffles to cool particulates from the suctioned air.
Claims20
An evacuation system comprising:
- an air handling system for drawing components comprising air, fumes, smoke, or particulate, or a combination thereof from a metal working application;
- an air conduit coupled to the air handling system for conveying the components from the metal working application towards the air handling system;
- and
- a hood coupled to the air conduit and configured to be positioned at the metal working application, the hood comprising an outer shroud, an inner deflector disposed in the outer shroud and defining a first sharp turn for the components drawn between the outer shroud and the inner deflector, and an inlet tube disposed in the inner deflector and defining with the inner deflector a second sharp turn for the components.
An evacuation system comprising:
- an air handling system for drawing components comprising air, fumes, smoke, or particulate, or a combination thereof from a metal working application;
- an air conduit couple to the air handling system for conveying the components from the metal working application towards the air handling system;
- and
- a hood coupled to the air conduit and configured to be positioned at the metal working application, the hood comprising a structure defining a circuitous path for particulate that, in operation, allows the airborne components to pass through the hood to the air conduit but causes particulate to cool the components.
A fume evaluation system comprising a hood configured to be coupled to the air conduit and to be positioned at the metal working application, the hood comprising a structure defining a circuitous path for the components that, in operation, allows the airborne components to pass through the hood to the air conduit but causes the particulate matter to cool the components.
