    Abstract: The present invention relates to an antimicrobial filter adopting optical fibers and to an air cleaner comprising the same. More particularly, the present invention relates to an antimicrobial filter using optical fibers and to an air cleaner comprising the same, in which ultraviolet rays, visible light or natural light is emitted directly through the surface of optical fibers contained in a filtering material, thus effectively killing, in a short time, microorganisms collected in the filtering material, such as bacteria, fungi, or viruses, which are harmful to the human body. Furthermore, a photocatalyst may be coated on the surface of the filtering material to achieve an improved sterilization effect. Thus, the deterioration of the sterilization effect caused by dust particles being continuously collected at the surface of filter fiber, which are disadvantages of existing antimicrobial filters, can be overcome.

    Abstract: An apparatus separating carbon dioxide from combustion gas using separation membranes, which includes: a first separation membrane in which combustion gas is injected into an inlet side of the first separation membrane; a second separation membrane in which residue gas of the first separation membrane is injected into an inlet side of the second separation membrane; and a third separation membrane in which permeate gas of the first separation membrane is injected into an inlet side of the third separation membrane, wherein at least a part of permeate gas of the third separation membrane is captured, and residue gas of the third separation membrane is injected into the inlet side of the first separation membrane or the second separation membrane. The present invention can be easily applied to an actual process by efficiently separating carbon dioxide using separation membranes.

    Abstract: The present invention provides a dust collector which includes a chamber divided into an inlet chamber and a discharge chamber by a barrier, and a bag filter which is installed inside of the inlet chamber, and is formed in a shape having an inner space and an opening part by a filter medium, so as to communicate with the discharge chamber through the opening part, wherein a treatment gas is introduced into the inlet chamber and is filtered while passing through the filter medium of the bag filter, then moves to the discharge chamber through the opening part to be discharged, and the bag filter has air permeability decreased toward the opening part. According to the bag filter and the dust collector, it is possible to achieve a high collection performance and a stable operation even when using a long bag filter due to improvement of uniformity of the filtration velocity along the length of the bag filter.
