A protective device protects the user from infection and may simultaneously immunize the user against future infection. In an embodiment, the protective device includes a disinfection chamber wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber such that the fluid discharged from the chamber comprises inactive microorganisms. The device may include a disinfection chamber in fluid communication with a face mask, with the chamber arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber to the mask, such that the fluid discharged from the chamber to the mask comprises inactive microorganisms.
摘要:
In an air purifying apparatus for removing contaminants, such as soot and the like, by burning contaminated air while passing the contaminated air through a filter heated by microwaves, the apparatus includes: a housing, which is hollow, and comprises an inlet on one side and an outlet on the other side; a ceramic filter of a longitudinal material, which is arranged in the housing in a longitudinal direction of the housing, and includes a plurality of partition walls formed so that a flow path where contaminated air flows may be divided in plurality; and a microwave generator configured to generate microwaves to be supplied to one end surface of the ceramic filter in a longitudinal direction thereof to heat the one end surface of the ceramic filter in the longitudinal direction.
摘要:
Apparatus and methods for reducing or eliminating undesirable air-borne substances, such as odors, bacteria, viruses, fungi, and toxins, are provided. A filter containing nanocrystalline metal oxide or metal hydroxide particles may be installed within an air handling apparatus such as an existing HVAC unit located within a building, and particularly within a home, or a portable air processor or purifier. The air handling apparatus comprises a blower which pulls air containing various undesirable substances from within the enclosed environment and directs it through a filtering device containing the nanocrystalline particles. The undesirable substances are sorbed by the nanocrystalline particles thereby creating a deodorized stream of air that may then be directed back into various portions of the enclosed environment or vented to the atmosphere.

The present disclosure provides devices and methods for making a light emitting diode (LED) activated photocatalyst air filter. One or more embodiments include a filter material that includes a photocatalyst, and a frame that includes an array of a number of LEDs positioned on the frame to project a wavelength of light directed toward the filter material, wherein the array of LEDs is positioned a distance from the filter material.
摘要:
A method for decontaminating bioaerosol with high concentrations of bacterial, viral, spore and other airborne microorganisms or biologic contaminants, in flight at high flow rates. A plasma screen created across the flow of air contaminated with airborne biologic agents renders contaminants non-culturable within millisecond. The technology may cooperate with heating, ventilation, and air conditioning (HVAC) systems. It may be particularly beneficial in preventing bioterrorism and the spread of toxic or infectious agents, containing airborne pandemic threats such as avian flu, sterilizing spaces such as hospitals, pharmaceutical plants and manufacturing facilities, treating exhaust ventilation streams, minimizing biological environmental pollutants in industrial settings, improving general air quality, and preventing sick building syndrome.
摘要:
The invention relates to a gas processing unit adapted for generating a surface plasma in the vicinity of a photocatalyst, that has a planar configuration. The photocatalyst is deposited in the form of a thin layer on a dielectric substrate and at least one plasma supply electrode is formed above the photocatalyst thin layer. Such a configuration increases the interaction between the plasma and the photocatalyst. The unit can be used for a gas processing of the pollution-control, odour reduction or bactericidal treatment type with a high efficiency.
摘要:
A plasma generation apparatus and method, which achieve both sterilization and deodorization of attached bacteria even under the condition that steam or fine droplets of water are present. A pair of electrodes is prepared, plasma discharge is carried out by applying designated voltage between the pair of electrodes, fluid passage holes are provided at corresponding parts of respective electrodes so as to communicate with each other, and steam or fine droplets of water are applied to the fluid passage holes and plasma generated around the fluid passage holes.
摘要:
A novel apparatus for the treatment, e.g., cleaning, humidifying, filtration and/or detoxifying, of ambient air incorporates a plant, soil, roots and a water reservoir to allow for effective filtration of air over an extended period of time. In particular, the device is designed with an air impeller system such that external ‘dirty’ air is circulated within the device in the proximity of the plant, soil, roots and/or water reservoir, thereby removing impurities, toxins and other undesirable chemicals from the air. The apparatus and methods of the present invention are readily applicable to a number of applications where air treatment is desired, e.g., household use. Moreover, by incorporating a plant system, the apparatus serves not only a functional but an aesthetic purpose as well.
