摘要： A filter for a respirator mask or other filtering applications, in which the filter comprises a filtering medium which may enhance performance of the filter, such as by providing enhanced filtration and/or lower resistance to airflow (e.g., lower respiratory resistance for a wearer of the respirator mask). The filtering medium may comprise active particles (e.g., activated carbon) that are derived from a polymeric precursor (e.g., polyvinylidene dichloride (PVDC)), impregnated with additives (e.g., metals and triethylenediamine (TEDA)), substantially uniform in size (e.g., monodispersed), and/or loose.

摘要： A dust filter mounted in a semiconductor waste gas treatment equipment comprising a housing having a chamber in the housing for passing a gas containing a water molecular and a dust through; and one or more main filtration boxes which can be implanted into the chamber by withdrawing way. One or more capturing rings and a filtering cotton for filtering the water molecular and the dust from the gas being disposed in the main filtration box, and the gas being sequentially passed through the capturing ring and the filtering cotton. It is an objective to solve a problem saying that it is not easy to clean the conventional dust filter because the structure of it is too complex.

摘要： Various embodiments of the present disclosure provide a portable industrial air filtration device employing an annular dual filter assembly to capture and remove impurities from the air surrounding the air filtration device, enabling the air filtration device to quickly and efficiently improve the quality and safety of the air. The air filtration device includes a two-piece housing including a lower housing component and a locking cover removably attachable to the lower housing component. The dual filter assembly is mounted within the housing between the locking cover and the lower housing component, and includes a removable self-supporting outer pre-filter surrounding a separately removable inner HEPA filter. The pre-filter initially filters the surrounding air by capturing relatively large or coarse impurities, and the HEPA filter further filters the air pulled through the pre-filter by capturing relatively small or fine impurities.

摘要： Air filtering devices are disclosed that contain a first filter cartridge having a cartridge inlet and a cartridge outlet and a curved filter bed having a concave surface disposed such that air to be filtered passes through the inlet, the curved filter bed, and the outlet. The air filtering devices also contain a blower assembly having a blower inlet in fluid communication with the cartridge outlet and a blower outlet, the blower assembly includes a motor proximate to the concave surface of the curved filter bed. The motor has a rotational axis such that the rotational axis is adjacent to the center of curvature of the curved filter bed. The air filtering device may be used in powered air purifying respirators.

摘要： A purification column is provided in which fluid is purified by flow through a purifying component. The column includes an annular wall defining a bore which, in use, contains the purifying component. The column further includes an inlet port to the bore comprising a first aperture through the annular wall, the inlet port being adjacent one end of the column. The column further includes an outlet port from the bore comprising a second aperture through the annular wall, the outlet port being adjacent the same end of the column as the inlet port. The column further includes a flow guidance device within the bore and removably connected to the inlet and outlet ports for guiding the fluid to the purifying component from the inlet port and for guiding the fluid from the purifying component to the outlet port. The flow guidance device maintains separation of the fluid flows to and from the purifying component.

摘要： In one example, we describe a method and system that uses iron oxide as its sole sorbent, specifically micron-sized nano-porous iron oxide particles. The sorbent is housed inside a horizontally rotating sorbent bed. The horizontally rotating sorbent bed is housed inside of a larger secondary compartment. At the top of the secondary compartment, there is an escaped sorbent particle containment membrane. One example uses a self-cleaning horizontally rotating sorbent drum membrane design that unclogs particulates lodged in the membrane by reversing particulate air flow direction during a small portion (e.g., about 20 degrees) of each full 360 degree rotation of the drum. When air flow passes through the porous horizontally rotating sorbent drum's membrane, which occurs at the location where the rotating sorbent bed membrane comes into contact with the air feed manifold, particulates are air-dislodged from the inner facing surface of the drum's membrane. Other variations are discussed.
摘要翻译： 在一个实例中，我们描述了一种使用氧化铁作为其唯一吸附剂，特别是微米级纳米多孔氧化铁颗粒的方法和系统。 吸附剂容纳在水平旋转的吸附剂床内。 水平旋转的吸附剂床容纳在更大的次级隔室内。 在次级隔室的顶部有一个逸出的吸附剂颗粒容纳膜。 一个例子是使用自清洁水平旋转的吸附剂鼓膜设计，其通过在滚筒的每个360度旋转的小部分（例如，约20度）内反转颗粒空气流动方向来阻止在膜中沉积微粒。 当空气流通过在旋转的吸附剂床膜与进气歧管接触的位置处发生的多孔水平旋转的吸附剂鼓的膜时，颗粒从鼓膜的内表面空气排出。 讨论其他变体。
