(54) Title
Equipment protecting enclosures
(57) Abstract

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the equipment is protected from radiation and hazardous gases by equipment enclosures. The equipment enclosures may be purged with gas.

Claims (9)

  1. A system comprising: a vibratory conveyor having motor components mounted on a structure, the motor components including materials that are susceptible to damage by ionizing radiation or ozone; an equipment enclosure that is opaque to ionizing radiation including X-rays having an energy of at least 0.1 MeV, the enclosure being configured to be positioned over the motor and having an open end that is dimensioned to provide a gap between the equipment enclosure and the structure when the equipment enclosure is in place and a conduit for flowing a purging gas into the equipment enclosure to remove ozone in fluid communication with a source of purging gas.
  2. The system of claim 1, wherein the gap is maintained by fixing the equipment enclosure relative to the conveyor using a stop, a groove, a spacer and/or a fastener.
  3. The system of claim 1, further comprising equipment for moving the equipment enclosure into and out of position over the conveyor components.
  4. The system of claim 3, wherein the equipment is selected from the group consisting of wheels attached to the equipment enclosure, tracks for sliding the equipment enclosure, wheels disposed below the equipment enclosure, sliders, linear guides and combinations thereof.
  5. The system of claim 3, wherein the equipment comprises slide rails on which the enclosure is mounted.
  6. The system of claim 1, further comprising electron beam irradiating equipment positioned such that the electron beam is directed towards a belt of the vibratory conveyor.
  7. The system of claim 1, further comprising a delivery device configured to deliver a particulate material to the vibratory conveyor, and a source of particulate biomass in communication with the delivery device.
  8. The system of claim 1, wherein the average gap width is from about 1 mm to 60 mm.
  9. The system of claim 1 wherein the enclosure is formed of a material having a Z value of at least 25.
