Abstract
An apparatus is disclosed for mixing ambient air and a hazardous gas with the gas being admitted to the apparatus via an inlet conduit. A rake disposed for travel within said conduit periodically dislodges deposits from the conduit interior with rake travel being along conduit affixed guides. Openings defined by the rake permit a gas flow at all times. Projections on a conduit end wall dislodge deposits from disc edges defining openings. A rake actuator is in communication with a solenoid valve in circuit with a timer and controller for automatic operation of the actuator.
Claims6
In an apparatus for mixing a hazardous gas with air in a chamber to render the hazardous gas inert, the improvement comprising,
- hazardous gas conduit structure in said chamber and including an end plate,
- a rake supported for rectilinear travel in said conduit structure and having a perimetrical edge proximate an internal wall surface of the conduit structure for cleaning said conduit structure, said rake having a static rest position adjacent said end plate,
- an actuator imparting movement to said rake to remove hazardous gas deposits from the internal wall surface of said conduit structure,
- a rake control system for automatic actuation of said actuator at timed intervals to impart movement to said rake, said rake defining an opening through which a hazardous gas may pass, and
- said hazardous gas conduit structure including a projection on said end plate for insertion into said opening in said rake to remove accumulated deposits therein to ensure the passage of hazardous gas through the rake defined opening during rake travel through the hazardous gas conduit structure.
