    Abstract: A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed.

The precipitated metal sulfide may be made by the process of combining a metal source, sulfide source, and modifier to form the precipitated metal sulfide. The metal source may comprise iron, cobalt, nickel, copper, zinc, zirconium, molybdenum, silver, or gold salts. The metal salt may be selected from metal nitrate, metal sulfate, metal phosphate, metal acetate, metal carbonate, metal hydroxide, metal ammonium carbonate, and metal hydroxycarbonate. The sulfide source is selected from hydrogen sulfide (H2S), carbonyl sulfide (COS), salts of sulfide (S2?), salts of hydrosulfide (HS?), and salts of polysulfide (Sn2?). The modifier may be selected from alumina, silica, aluminosilicate, clay, zeolites, carbon, cement, titania, zirconia.

  • Patent number: 8834615
    Abstract: The present invention provides an air cleaning unit which contains a blower, an acid/alkaline filter device, and a particle filter device. The blower draws in outside air through the acid/alkaline filter device and produces an air flow through the particle filter device. The acid/alkaline filter device absorbs the acid/alkaline gases in the outside air. The particle filter device traps the particles in the air flow. Through this design, the blower draws in air filtered by the acid/alkaline filter device. The blower therefore does not suffer erosion and therefore the air cleaning unit enjoys prolonged operation life span.

  • Publication number: 20140224127
    Abstract: Provided are a space-saving filter that has a plurality of types of air purification capabilities with reduced pressure loss, and a compact air purifier that efficiently exerts a plurality of types of air purification capabilities. Since a body part of a deodorizing filter includes two pieces of deodorizing filter bodies each having the same thickness (hereafter referred to as thickness D) juxtaposed in a plane direction, the body part has the thickness of D. When the deodorizing filter bodies are laminated, the thickness of the body part becomes 2D or more. The body part has a reduced pressure loss and space in a thickness direction compared with a filter in which the deodorizing filter bodies are laminated. The first deodorizing filter body mainly removes aldehyde-based odor components and the second deodorizing filter body mainly removes amine-based odor components.

  • Patent number: 8778061
    Abstract: The reaction exhaust gas from which chlorosilanes and hydrogen chloride have been removed in a hydrogen chloride absorption unit (30) is introduced to an adsorption unit (50) to recover a purified hydrogen (S105). Activated carbon is packed in the adsorption unit (50), the gas, which is mainly composed of hydrogen, is passed through the activated carbon-packed layer during which unseparated chlorosilanes, hydrogen chloride, nitrogen, carbon monoxide, methane, and monosilane contained in the gas are adsorbed on the activated carbon and removed from the gas, and thereby the purified hydrogen is obtained. Nitrogen, carbon monoxide, methane and monosilane are a compressed gas in the state of adsorption, whereas hydrogen chloride and chlorosilanes are a liquid in the state of adsorption, and require a vaporization heat during desorption. Using these properties, the separation of hydrogen chloride and chlorosilanes from other impurity components is possible merely by separating the pathways for the desorbed gas.
