摘要:
The present invention removes, by a preprocessing unit, harmful chemical materials and radioactive materials supplied to a positive pressure chamber and a negative pressure chamber and supplies same, removes contaminants discharged to the outside from the negative pressure chamber and sterilizes bacteria and floating viruses and discharges same, and adjusts, by a control circuit of a control panel, the rotating speed (RPM) of an air supply/discharge fan and adjusts the opening rate of an electric damper according to data that is measured in a pressure sensor provided in a space in which the positive pressure and the negative pressure are to be maintained and is transmitted in real time.

The nanoparticle purifying system includes a container having an interior portion including a plurality of aluminum plates. Each of the plurality of aluminum plates includes a solid filtering agent, such as activated charcoal and, optionally, sodium tetra borate. The container can further include an inlet for receiving polluted air, an outlet for discharging purified air, and a pathway extending between the plurality of aluminum plates from the inlet to the outlet. The nanoparticle purifying system includes a removable lid for disposing on the container. Each of the plurality of aluminum plates can include an adhesive, such as hot glue and/or carpet glue, for attaching the solid filtering agent to the surfaces of the plurality of to aluminum plates and interior surfaces of the container.
摘要:
A method of using a metal organic framework (MOF) comprising a metal ion and an at least bidendate organic ligand to catalytically detoxify chemical warfare nerve agents including exposing the metal-organic-framework (MOF) to the chemical warfare nerve agent and catalytically decomposing the nerve agent with the MOF.

摘要:
A filter unit for use in a filter box assembly, the filter unit comprising a particulate filter layer and a gas filter layer, the particulate filter layer being configured to bias towards the gas filter layer, exerting pressure thereon. There is also described filter box assemblies (including a duel filter assembly) comprising the filter unit, and a respiratory protective device comprising the filter unit. Also described is a method of manufacturing a filter unit with a gas filter layer and a particulate filter layer, wherein a force is applied to the particulate filter layer causing it to fix the gas filter layer in place. Also described is a method of manufacturing a dual filter assembly wherein a casing is twice reversibly attached to and detached from a support surface, filter units being added to the casing when the casing is attached to the surface.
摘要:
A decontamination system useful for treating articles that have been exposed to nuclear, chemical or biological (NBC) agents may comprise a decontamination unit, a catalytic oxidation (CATOX) reactor connected to decontaminate off gases from the decontamination unit and a selector valve The selector valve may be configured to allow output gases from the CATOX reactor to pass to an exhaust during steady-state operation of the CATOX reactor and to allow said output gases to re-enter the CATOX reactor during warm-up of the CATOX reactor. Warm-up of the CATOX reactor may be quickly achieved as a result of recycling the output gases through the preheater during warm-up.
摘要:
A process and sensor device are disclosed that employ metal β-diketonate polymers to selectively capture gas-phase explosives and weaponized chemical agents in a sampling area or volume. The metal β-diketonate polymers can be applied to surfaces in various analytical formats for detection of: improvised explosive devices, unexploded ordinance, munitions hidden in cargo holds, explosives, and chemical weapons in public areas.
摘要:
Ice-clad machinery and equipment in very cold environments are made more easily recoverable by enclosing the machinery and equipment in an environmentally contained area and introducing desiccant dehumidified air into the contained area to lower the vapor pressure in fostering a “sublimation” process conversion from the solid state of the ice to a gaseous state which can be exhausted without first going through any intermediate liquid state.
摘要:
Metal oxide area decontamination apparatus (10) is provided which is designed for rapid, emergency situation decontamination of areas contaminated with potentially harmful or lethal chemical and/or biological warfare agents or other hazardous substances. The apparatus (10) preferably includes a pressurizable metallic container (12) equipped with a valve-type delivery nozzle assembly (16), so that upon a manipulation of the assembly (16), a spray of metal oxide and/or metal hydroxide particles is generated; the particles are selected and sized in order to destroy or chemisorb the contaminating agents. The preferred decontamination agent is MgO aggregated to an average aggregate size of from about 50 nm-10 microns. The particles are mixed with a gaseous or liquid propellant within the container (12) allowing rapid and thorough particle cleanout when the nozzle assembly (16) is actuated.
摘要:
A self-powered, personally wearable air purifier includes a sequence of packed bed filter media packets having filter media therein of specifically targeted types that will absorb those ambient air pollutants that have been identified as being particularly dangerous to human health. A HEPA filter is included for the removal of particulate matter that will have adhered thereto many of such pollutants. Media types can be selected to meet different environmental circumstances, including normal highway or city center air, or terrorist attacks of chemical, biological or “dirty bomb” types as on a battlefield or similar environments. Shoulder straps and a chest strap are provided for wearing the apparatus on a user's back, or other means such as a shoulder pouch can also be employed. Emergency substitution of filter media using thermal insulation from the clothing of the user is available upon depletion of the normal media material.
