摘要： Apparatuses, systems, and methods operable to reduce catalyst fouling by removing solid particulates from a heated fluid stream upstream of a catalyst using one or more flue gas strainer apparatuses that may be cleaned or serviced without ceasing or disrupting heating or catalytic operations. The flue gas strainer apparatuses may include a housing having a front end and a back end, the housing comprising a receiving portion, an outer edge, an inner edge, and an inner bore extending from the front end to the back end of the housing along the inner edge. The inner bore is operable to allow a heated fluid stream to pass therethrough. The flue gas strainer apparatus may also include a moveable strainer portion comprising one or more removable mesh portions. Each of the one or more removable mesh portions may have a plurality of pores and configured to capture solid particulates suspended in the heated fluid stream. The one or more removable mesh portions may be operable to be removingly received in the receiving portion of the housing.

摘要： An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

摘要： An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter comprises a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium comprises a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

摘要： Provided are a recyclable electret filtering membrane, a preparation method therefor and a cleaning and charge regeneration method therefor. The preparation method includes: dissolving fluorine-containing polymer particles and polyoxyethylene particles in deionized water to prepare a spinning solution, and then performing electrostatic spinning, calcining, cooling, drying and corona charging to obtain the recyclable electret filtering membrane. A surface of the filtering membrane is subjected to water drop rolling cleaning and friction electrification after dust holding, and then dried to realize charge regeneration and reuse. The filtering membrane obtained in the present invention has an initial surface potential of (−600)-(−950) V, the potential can be regenerated to (−700)-(−1000) V by water drop rolling and electrification after dust holding, the charge recovery rate is 90%-125%, the dust removal rate is 90%-100%, and the filtering efficiency for PM2.5 is equal to or greater than 94%.

摘要： Virus and microbe-killing, self-sterilizing resistive heated air filters and methods of making and using same methods. The air filter is includes laser-induced graphene (LIG), a porous conductive graphene foam formed through photothermal conversion of a polyimide film (or another source or source of polymer or other LIG precursor material) by a laser source. The LIG in the air filter can capture particulates and bacteria. The bacteria cannot proliferate even when submerged in culture medium. Through a periodic Joule-heating mechanism, the filter easily reaches greater than 300° C. This destroys any microorganisms including bacteria, along with molecules that can cause adverse biological reactions and diseases such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions.

摘要： A filtering device for removing particles from a fluid of a patient is provided. The filtering device being implantable in the patient's body and comprising a cassette comprising a revolving member, said revolving member having at least two segments each holding a respective filter. The device further comprises a tube forming a fluid passageway through one of the filters in said cassette, wherein the cassette is adapted to, upon revolution of the revolving cylinder, change the filter positioned in the fluid passageway from a first one of said filters to a second one of said filters, thereby allowing particles present on the first filter to be moved away from the fluid passageway, while at the same time changing the filter positioned in the fluid passageway.
