Abstract: A method for removing moisture from gas containing vapor of a solvent using a dry dehumidifier, includes removing moisture from at least a part of dehumidifier regenerating outlet gas and reusing the dehumidified gas as regenerating gas. Reuse of partial gas on the regenerating outlet side makes it possible to condense efficiently vapor of a solvent contained in exhaust gas as dehumidification is continued, to produce small quantity of high concentration gas thereby, and in case of making removal treatment of vapor of a solvent to miniaturize an apparatus for this purpose as well as to reduce prominently costs required for equipments and others.

Abstract: A dehumidified/humidified air supply apparatus includes two sets of air passages including heating units disposed at an upstream side thereof, a dehumidifying/humidifying unit having two portions disposed at a downstream side thereof and a blower. When dehumidified air is supplied by the dehumidifying/humidifying unit of the first air passage, the dehumidifying/humidifying unit is dehumidified by air which is heated by the heating unit of the second air passage. When humidified air is supplied by the heating unit of the first air passage and the dehumidifying/humidifying unit, the dehumidifying/humidifying unit is humidified by air of the second air passage. The dehumidifying/humidifying unit is moved between the first air passage and the second air passage by a driving unit.

Abstract: A low-humidity working apparatus comprising a housing (8) forming a working chamber (9), a dehumidifying apparatus (18), and air supply means. The metal housing (8) forming the working chamber (9) is provided with a laterally elongated operating hole (30), a plurality of strip flexible sealing members are arranged adjacent to each other and suspended in this operating hole (30), and a laterally elongated window hole (31) is disposed in the vicinity of and above the operating hole (30) and closed by a light-transmitting window plate. The dehumidifying apparatus (18) circulates the air in the working chamber (9) by sucking the air therefrom, cooling the sucked air by an evaporator (48) of a compression refrigerating machine (41), dehumidifying the cooled air by a dehumidifying rotor (61) carrying a dehumidifying agent, and returning the low-humidity air from the dehumidifying rotor (61) to the working chamber (9).

Abstract: A catalytic oxidation apparatus comprising a cylindrical honeycomb structure including a multiplicity of small passageways extending therethrough in parallel and having an oxidizing catalyst deposited thereon, a number of the passageways being separated as a catalyst regenerating zone from the other passageways, the regenerating zone being continuously shiftable throughout the entire honeycomb structure circumferentially thereof to render the honeycomb structure serviceable, from portion to portion, as the regenerating zone provided by the number of passageways.

Abstract: An apparatus for removing moisture and odors comprising a cylindrical honeycomb structure made by corrugation from paper uniformly containing an adsorbent, including a multiplicity of parallel gas passageways and having deposited thereon a water absorbent at least at one side thereof serving as an outlet for the gas to be treated, a number of the gas passageways being separated as a dehumidifying and deodorizing zone from the other passageways serving as a regenerating zone, the dehumidifying and deodorizing zone being continuously shiftable throughout the entire honeycomb structure circumferentially thereof to render the honeycomb structure serviceable, from portion to portion, as the dehumidifying and deodorizing zone provided by the number of passageways.
