The present invention discloses a dust removal device using expansion pressure. A dust removal device using expansion pressure according to one embodiment may comprise an inlet chamber allowing mixed air including dust to flow inside and including an outlet for discharging the dust downward; a dust collecting chamber disposed at a bottom of the inlet chamber and sealed in a state of communicating with the inlet chamber and the outlet to collect the dust discharged through the outlet; a supplying pipe entering into an inside of the inlet chamber and extending toward the outlet to supply the mixed air into the inlet chamber; a first blower providing a blowing force for sucking in the mixed air and supplying the mixed air through the supplying pipe; an air exhaust duct connected to communicate with the inlet chamber to guide air separated from the dust to be discharged to outside, wherein a communication part of the air exhaust duct, which communicates with the inlet chamber, has a certain size allowing the inlet chamber to generate an expansion pressure inside, and a second blower providing a blowing force to discharge the air inside the inlet chamber to the outside through the air exhaust duct, wherein the supplying pipe and the outlet are spaced apart from each other, and a separation distance between the supplying pipe and the outlet is longer than a range that the mixed air propelled from the supplying pipe can reach to, so that the expansion pressure of the mixed air supplied to the inlet chamber accelerates separation action caused by specific gravity difference between the air and the dust.

In a solid waste treatment system comprising an autoclave (201) not having a particulate filter at its outlet, a method of removing particulates suspended in steam discharged from the autoclave following processing of solid waste is disclosed. The method includes discharging steam from the autoclave; routing the steam to the inlet (301) of a separation vessel (209) that further includes an outlet (303) and a baffle (302) between the inlet and the outlet; and collecting particulates (304) that drop from suspension in the steam at the bottom of the separation vessel. The baffle is configured so that steam is incident upon the baffle to reduce its flow velocity.

Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof.

A honeycomb structure of the present invention includes a honeycomb structure body and a pair of electrode member arranged at a side surface of the honeycomb structure body. The honeycomb structure body has an electrical resistivity of 1 to 200 cm, and the respective pair of electrode members is formed into a band-like shape extending in a direction in which the cells extend. In a cross section perpendicular to the cell extending direction, one of the electrode members is arranged opposite to another of the electrode members sandwiching a center of the honeycomb structure body. One or more of slits, which being open to a side surface, are formed at the honeycomb structure body. At least the one slit is formed so as not to intersect with a straight line connecting center portions of the respective pair of electrode members in the cross section perpendicular to the cell extending direction.

A drain adaptor comprising a stem and drain body. The stem comprises a breather opening defined by a surface of the stem and a drain opening defined by a surface of the stem. The drain body comprises another breather opening defined by a surface of the drain body and another drain opening defined by a surface of the drain body, wherein the stem extends from the drain body, and wherein a breather passageway extends from the breather opening of the stem to the other breather opening of the drain body, and wherein a drain passageway extends from the drain opening of the stem to the other drain opening of the drain body.

This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

A compressor compresses a coolant gas returned from a refrigerator and supplies the coolant gas to the refrigerator. A compression capsule compresses the coolant gas and cools compression heat generated by compressing the coolant gas, using oil. An oil separator separates and stores the oil contained in the coolant gas compressed by the compression capsule. A capsule oil level gauge that measures an oil level in the compression capsule. A separator oil level gauge that measures an oil level in the oil separator.
