Abstract:
PURPOSE:To purify waste hot water while the heat of the waste hot water is collected by a method wherein the outer surface of a heat collecting coil for collecting the heat of the waste water is made to serve as a purifying contact member. CONSTITUTION:The waste hot water is introduced into a waste hot water tank 8 from a waste hot water inlet port 4. The waste hot water is purified by coming into contact with an organic film attached to the surface of the heat exchange coil serving as the contact member while it passes along the coil and the heat of the waste hot water is collected while water flows through the heat exchange coil 2 from the inlet port 1 and discharged from the outlet port 3 of the coil. Further, air bubbles are generated from a vent port 6 to thereby promote the propagation of aerobic bacteria and at the same time, to agitate the waste hot water so as to increase the heat exchange and heat transfer efficiencies.

PROBLEM TO BE SOLVED: To positively utilize a moisture adsorbing material as latent heat storage (moisture storage) and as a heat storage medium instead of ice by using a large quantity of moisture adsorbing material although an adsorption type refrigerator is regarded as a defect of enlargement of size. SOLUTION: Although there was an idea of utilizing a part of a building structure with regard to moisture storage, it is not fusion heat of ice or the like quantitatively and mechanically, and there has been no idea of storage of heat of vaporization. When compared with a conventional rotor type desiccant air conditioner, since the moisture absorbing material forms a thick layer, "waste gas of a soiled engine" or the like can be utilized as it is in regeneration only by allowing a heat exchange pipe to pass through the inside of the layer. When absorbing moisture, outside air or return air is allowed to flow through the heat exchange pipe to attain isothermal dehumidification. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
A reaction tube of a reaction apparatus includes a circular cylindrical inner tube and an intermediate tube disposed concentrically with the inner tube. A catalyst used in reforming reactions is charged in the gap between the inner and the intermediate tubes. The inner tube accommodates filler particles and is provided with a hollow member disposed therein in contact with the filler particles and capable of absorbing stress resulting from thermal expansion of the filler particles. By virtue of the provision of the hollow member which absorbs thermal stress of the filler particles that are caused to undergo thermal expansion by a high-temperature gas, such as a combustion gas, flowing through the inside of the inner tube, the apparatus is capable of preventing any deformation or breakage of the inner tube.
