Exhaust air from a coater drier is sent to a desorption zone of a VOC concentration rotor. Air which comes out of the desorption zone is sent to a heat exchanger and cooled, the cooled air which comes out of the heat exchanger is sent to a cooling coil which carries out VOC concentration recovery. Air which comes out of the cooling coil is sent to an absorption zone of the VOC concentration rotor. Air which comes out of the absorption zone is sent to the heat exchanger and heated. The heated air which comes out of the heat exchanger is sent to a heating coil to be used as supply air for a coater drier. A heat pump can be used for the cooling coil which carries out cooling condensation of the organic solvent and the heating coil which heats purified air as air supply for the coater drier.


GIKEN is a world-leading manufacturer of non-polluting pile press-in machines, advancing the spread of its original Implant Method as a technology allowing for the rapid construction of robust, highly earthquake-resistant buildings in constrained spaces in the interests of disaster prevention. In efforts to rebuild after the Great East Japan Earthquake and tsunami, and in preparation for a potential Nankai Trough earthquake, GIKEN's technologies are finding more and more use in seawall reinforcement, earthquake-proofing for the retaining walls of aging roadways, railway embankments, and bridge piers, as well as landslide prevention for mountainous areas. GIKEN was founded in 1967 with a vision to remove pollution from construction work, and celebrated the 50th anniversary of that founding this January. In 1975, GIKEN made a breakthrough with the development of the Silent Piler, a vibration-free and virtually noise-free hydraulic press-in machine using the press-in principle, setting it years ahead of the rest of the world technologically. This use of a light, compact machine radically transformed accepted principles of piling, eliminating construction-related problems from piling in one fell swoop. The "press-in principle" refers to the mechanism whereby piles are installed using static load generated from hydraulic rams, with the reaction force derived from the extraction resistance force of previously-installed piles. One of the biggest advantages of using this principle is the ability to leverage a small machine to yield significant energy using the power of the Earth. This Implant Method, which utilizes Silent Pilers, has built an extensive track record across 37 countries worldwide. Further, underground spaces created by the Press-in Method now house 50 Eco-cycle parking facilities across 19 locations in Japan, built under the vision of "Culture Aboveground, Function Underground". These facilities have garnered much attention with their minimal aboveground exposure with a compact entrance booth and their incredibly convenient bicycle withdrawal, which can be as fast as eight seconds. We at GIKEN continue to strive to revolutionize construction technology around the world in a joint pursuit of company value and protection of lives, culture, history and wealth against disaster, seeking to underpin a safer, prosperous society.

An adsorption rotor has a surface layer which can be detached and replaced when performance degrades. A metal aggregate is extended in the width direction of the rotor element so that attachment-and-detachment adsorption rotor elements can be attached thereto using bolts and a perimeter griddle fixing bracket, thus resulting in protecting an upper part of the integral-type adsorption rotor element. In this way, the weight of the attachment-and-detachment adsorption rotor elements can be made light, resulting in them being fixable only using bolts, without special tools or skilled technicians. Moreover, because the detachment-and-replacement procedures can be performed from a rotor spindle side, thus from inside of a chamber, a heavy industrial machine is not required.

A desiccant air conditioner has a high energy efficiency due to the absence of excessive heat loss due to ventilation. In order to meet this requirement, the desiccant air conditioner is equipped with a honeycomb rotor wash-coated with agents having capabilities of absorptions of humidity, carbon dioxide and nitrogen, and this honeycomb rotor is divided into at least an absorption zone and a desorption zone. The air in a room is, after being passed through the absorption zone, fed back to the room, and the air which is passed through the desorption zone is exhausted into outside of the room. In this way, carbon dioxide and nitrogen in a room, the latter quantity being corresponded to that of the consumed oxygen in the room, are exhausted into outside of the room, allowing to exhaust carbon dioxide and at the same time to keep the oxygen density to within an allowed limit without the need of excessive ventilation.

An absorption-type carbon dioxide removal/condensing apparatus is removes or condenses carbon dioxide so that the apparatus secures high recovery efficiency. The apparatus has a honeycomb rotor holding a carbon dioxide absorbent, which is divided into at least a processing zone and a reproduction zone. After anyone of reproduction air for heating and a processing air is humidified by a humidifying device, both airs are ventilated into the zones, respectively. Thereby, the apparatus can improve absorption performance and density performance. If the honeycomb rotor is further divided into at least first and second processing zones, an air to be processed is humidified by a humidifier to ventilate into the first processing zone, and then a portion or all of the processing air which passed through the first procession zone is passed through the second procession zone (second pass).

Exhaust gas after coal or oil burning has moisture, which hinders carbon dioxide adsorption. It is necessary to completely remove this moisture with the minimum use of energy. The exhaust gas from the burning apparatus is first lowered of its temperature by passing through an total heat exchanger rotor, and the resultant gas which has low temperature and humidity is sent to a carbon dioxide adsorption rotor, thereby removing carbon dioxide from the gas, which is then sent through the total heat exchanger rotor with the resultant desorption of moisture adsorbed there and is exhausted to outside atmosphere, while the carbon dioxide adsorption rotor is desorbed of its carbon dioxide using water vapor, with the resultant very humid carbon dioxide to be sent to a processing system such as for underground burial.

[Objective] When performance of an adsorption rotor falls, or even if an adsorption rotor surface layer gets clogged, the present invention provides an adsorption rotor which can be detached and replaced only of its surface layer. [The means of solution] The metal aggregate is extended in the width direction of the rotor element so that the metal aggregate can fix the attachment-and-detachment adsorption rotor elements 6 by piling them up using bolts with the perimeter griddle fixing bracket 7, thus resulting in protecting the upper part of the integral-type adsorption rotor element. In this way, the weight of the attachment-and-detachment adsorption rotor elements 6 can be made light, resulting in them being fixable only using bolts, and thus of no necessity of using a special tool for the work, enabling unskilled personnels to easily carry out the detachment-and-replacement procedures. Moreover, because the detachment-and-replacement procedures can be performed from a rotor spindle side, thus from inside of a chamber, there is no necessity of using a heavy industrial machine etc., resulting in much reduction in the cost for the procedures.
