US Patent:

7418895, Sep 2, 2008
Filed:

Dec 23, 2003
Appl. No.:

10/744703
Inventors:

John L. Donovan - Danvers IL, US
Jay M. Quimby - Parsippany NJ, US
McRea B. Willmert - Wilsonville OR, US
Assignee:

DeMil International, Inc. - Englewood CO
International Classification:

F42B 33/00
US Classification:

86 50, 588403, 588900
Abstract:

Apparatus and methods are provided for purging an airlock cavity created between the airlock access door and the primary explosion chamber opening sealing mechanism. According to one embodiment of the present invention, an airlock device is used to ensure that, in the event toxins are released from the primary explosion chamber opening sealing means, the toxins are properly handled and are not inadvertently released into the atmosphere. In one embodiment, negative pressure is used to vacuum the entrained air within the airlock cavity subsequent to an explosion. To facilitate the sweeping and exhausting of the cavity, an orifice in the access door may be operable to allow the flow of ambient air through the airlock access door.

F23D 7/00
US Classification:

422112, 422176, 110237, 110240, 110241, 110242, 110235, 86 50
Abstract:

Systems and methods for treating hazardous materials are disclosed. One exemplary implementation provides a system for rendering chemical weapons materiel less hazardous. This system includes a detonation chamber, an expansion chamber, and an emission treater adapted to treat gas from detonation of the chemical weapons materiel. The emission treater yields a substantially dry residual waste stream and a treated gas suitable for venting to atmosphere. The emission treater may treat the gas with an alkaline powder that interacts with the gas, producing the residual waste stream.
