  • Patent number: 10449264
    Abstract: A device in which exhaust fluid from a facility or equipment for treating biologically active material is heated to a temperature of at least 400° C. to kill or denature hazardous agents, and conveyed through a metal filter with no more than 0.1 ?m pore size, which is heated, preferably by the fluid, to essentially the same temperature. The relevant temperature is maintained during operation in both the fluid and the filter. Since the filter is dimensioned to trap microbial agents like bacteria and viruses and the temperature of the filter surfaces is sufficient for sterilization, microbial agents are bound to come into contact with said surfaces and a very high degree of sterilization certainty is reached. The filter is welded to the device body to provide a seamless structure. Heating and filtration are both alone sufficient for removing biohazardous agents, so the device provides double security.

The means for drawing air from the surrounding environment into the apparatus (120 and/or 220) mobilizes latent pathogens in the environment and draws them into the apparatus (100 and/or 200) for sterilization and disinfection. The air management chamber (130 and/or 230) provides for exposure of the airborne pathogens to UV radiation, via UV LEDs (150 and/or 250), with a dosage sufficient to penetrate the cell walls and destroy the pathogens. The electronics and control module (110 and/or 210) powers the apparatus (100 and/or 200) and interfaces with the electronic components. The housing (170) forms the outer shell of the apparatus (100).

  • Patent number: 8980172
    Abstract: An odor control system includes a controlling gas source, a gas sensor module for detecting a dominant gas, the gas sensor module, a sample conduit, and an electronic control unit. The controlling gas source supplies a controlling gas to react with a foul air gas in a foul air volume. The gas sensor module for detects a dominant gas and generates a detection signal. The sample conduit routes reacted gas from the four air gas volume to the gas sensor module. The electronic control unit is configured to receive the detection signal from the gas sensor module and to automatically control the controlling gas source in response thereto. The detection signal has a signal direction relative to a signal baseline set such that the signal direction will differ depending on whether the controlling gas or the foul air gas is the dominant gas.

  • Patent number: 8980171
    Abstract: A system and method for purifying air via low-energy, in-situ regenerated silica-titania composites is described. The silica-titania composites can be synthesized with various pore sizes, photocatalyst loadings, and surface area, and can be applied in pellet/granular form or powdered and coated onto a surface. The system may operate with continuous UV irradiation for continuous oxidation of pollutants and inactivation of pathogens. Alternatively, the system may operate with intermittent UV irradiation, whereby pollutants are adsorbed in the absence of light, followed by oxidation of sorbed pollutants and regeneration of silica-titania composites upon irradiation with UV light. The oxidation/regeneration step may or may not incorporate sweep air. This system and method may be used for removing pollutants, such as Volatile Organic Compounds, from aircraft cabins, space exploration vehicles and architectures, mass transit vehicles, and residential and commercial buildings.

  • Patent number: 8936671
    Abstract: An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.

  • Publication number: 20150017060
    Abstract: A process and apparatus for disinfection of spaces using a disinfecting liquid droplet spray atomization are described, in which an electric fan 107 is used to dispense the atomization from an atomization chamber 104 via venture outlets 106 into the space to be disinfected. The operation of the electric fan 107 is modulated in a substantially random sequence to vary the rate of dispensing into the space in order to improve the dispersal of the atomized droplets in the space and hence the efficacy of disinfection.
