It is intended to provide a volatile organic compound treatment apparatus having: an absorption treatment chamber in which absorption frames having absorbents for absorbing volatile organic compounds are aligned in a direction of a gas flow; an absorbent recovery treatment chamber that is provided with a discharge unit having a high voltage electrode, a ground electrode, and a dielectric; and a transfer mechanism for transferring the absorption frames present in an upstream of the gas flow to the absorbent recovery treatment chamber and transferring the absorption frames in the absorbent recovery treatment chamber to a downstream of the gas flow. The volatile organic compound treatment apparatus is capable of decomposing VOC without generating a large amount of harmful NOx and reduced in apparatus cost.

Apparatus for volatile organic compound treatment and method of volatile organic compound treatment

A temperature-humidity exchanger comprising: a moisture permeable membrane which transmits moisture therethrough; a dry gas separator in which low-temperature dry gas is caused to flow; and a wet gas separator in which high-temperature wet gas is caused to flow, in which the moisture permeable membrane, the dry gas separator, the moisture permeable membrane, and the wet gas separator are repeatedly stacked in the stated order, wherein in the dry gas separator and the wet gas separator: a plurality of channel grooves which are divided by half in the stacking direction, are open to a direction in which the channel grooves come into contact with the moisture permeable membrane, and are arrayed parallel to one another are provided; an aggregate communication groove which is made to communicate with both end portions of the plurality of channel grooves, for aggregating gas caused to flow through the channel grooves to at least one is provided; and a supply manifold and an exhaust manifold which are made to communicate with the aggregate communication groove and penetrate the separators in the stacking direction are provided; and a flow of the dry gas caused to flow in the channel grooves of the dry gas separators and a flow of the wet gas caused to flow in the channel grooves of the wet gas separators are counterflows.

Temperature/humidity exchanger

A humidifier and a method for producing it can reduce gas leakage through inside the surfaces of humidifying membranes or through interfaces between the humidifying membranes and separators. The humidifier includes water permeable humidifying membranes and gas separators each having one or two channels opened at least one side in a direction of lamination, through which at least one of a dry gas and a wet gas is caused to flow. A humidifying membrane, a gas separator, a humidifying membrane and a gas separator are repeatedly laminated one over another in this order, or a gas separator, a humidifying membrane and a gas separator are repeatedly laminated one over another in this order. Each gas separator has a frame-shaped portion surrounding the one or two channels, and that portion of each humidifying membrane which, when laminated, faces the frame-shaped portion of a corresponding gas separator is filled with a resin.

Humidifier and a method for producing the same

A volatile organic compound treatment apparatus including an adsorber coming into contact with a gas to be treated and adsorbing volatile organic compounds; a plurality of pairs of electrodes, divided into a plurality of groups, which generate electric discharge so that a part of the adsorber is exposed to the electric discharge; and an electric discharge control mechanism for controlling whether or not the electric discharge is generated in what pair of the electrodes by applying a voltage to every group of the pair of electrodes such that different parts of the adsorber are sequentially exposed to the electric discharge.

Volatile organic compound treatment apparatus

Provided is an inexpensive temperature-humidity exchanger having reliably gas-sealed gas manifolds and delivering a gas at high pressure and high dew-point temperature. Upper and lower seal portions surrounding gas manifolds to which the gas is supplied or from which the gas is discharged are provided. The upper and lower seal portions, which partially extend across an aggregate communication groove, are respectively constituted by upper and lower seal formation plates that are arranged in a two-stage manner in a laminating direction. The upper and lower seal portions have flat faces extending in the laminating direction. Furthermore, the upper and lower seal formation plates are disposed such that their projections in the laminating direction are offset from each other.

Temperature-humidity exchanger

A reformer that includes a housing including a tubular member and an end plate member hermetically joined to the tubular member. The housing defines within it a first fluid flow path and a second fluid flow path in a heat exchanging relationship with each other. A reforming catalyst is disposed within the first fluid flow path. The tubular member has a tubular end, and the end plate member has an abutting rim that contacts with and extends along the tubular end of the tubular member and that is folded together over an entire circumference thereof to define a folded hermetic seam between the tubular member and the end plate member. The reformer can be low-priced and its manufacture is easy and efficient.

Reformer

A battery body, which is composed of a laminated body obtained by laminating a cathode and an anode via a separator or a wound body obtained by winding them in a laminated structure and a plurality of leads connected to the cathode and the anode, is contained in a flexible package, and after an electrolyte solution is injected thereinto, an opening of the package is sealed at pressure which is lower than atmospheric pressure and is reduced to not less than vapor pressure of the electrolyte solution so that a thin battery is fabricated. A rise in pressure in the battery due to generation of gas in the battery and volume expansion of the gas can be restrained when the battery is maintained at high temperature.

Thin battery and method of manufacturing

A battery package including laminate sheets adhered each other along their peripheral to form a container portion for receiving an electrode assembly and a seal portion. The seal portion surrounds the container portion and protrudes outwardly from side faces of the container portion. The seal portion has enough width to maintain the container portion free from moisture for long periods of time. The laminate sheets include a heat-adhesive polymer layer and a metal layer which stops moisture and provides a shape-maintaining ability to the laminar sheets. The seal portion is folded or curled to reduce a projection area of the battery package.
