摘要:
The present invention relates to a process and devices to clean and reuse displaced outgoing air containing additives (e.g. solvents) or pollutants, especially to clean and reuse outgoing air with solvents displaced from drying devices in offset web-fed rotary presses. In the first stage of the process the outgoing air is passed through at least one condenser so that the additives or pollutants contained in the air can be condensed out. In the second step of the process the outgoing air treated from the first stage of the process is passed through at least one separator element in order to clean said air further from condensed additives or pollutants contained therein. Finally, the outgoing air treated after the second step of the process is returned for renewed absorption or suction of additives and pollutants.

An exhaust gas recovery method and apparatus comprising: a first process in which volatile organic compound gas in exhaust gas from a exhaust gas discharging source (10) is absorbed into water by a scrubber (14); a second process in which water including the volatile organic compound, which is obtained in the first process, is frozen and the volatile organic compound herein concentrated such that the water including the volatile organic compound is separated into water including a high concentration of the volatile organic compound, level of concentration being higher than that of the water including the volatile organic compound which is obtained in the first process, and ice; a third process in which cold of the ice obtained in the second process is used; and a fourth process in which the water including a high concentration of the volatile organic compound, which is obtained in the second process, is reused, is provided.
摘要:
An organic solvent gas adsorption element comprising a single honeycomb structure on which a plurality of organic solvent gas adsorbents having different adsorption characteristics are supported in separate sections made in the area of the honeycomb structure by dividing either in the air flow direction or in the direction perpendicular to that direction. The adsorption element can treat air contaminated with different types of solvent gases simultaneously.

In the cleaning of a humid gas flow containing gaseous impurities, the gas flow is dehumidified by cooling. The cooled gas flow is reheated and then conducted through a device (7') for the adsorption of gaseous impurities. A desorption-gas flow is heated so as to form a hot-gas flow, which is conducted through the adsorption device (7') in order to clean the latter. The contaminated hot-gas flow is conducted to a combustion device (10') in order to be burnt. Hot combustion gases are removed from the combustion device (10') in order to take part in at least one of the heating processes by being introduced into and mixed with the cooled gas flow and the desorption-gas flow.
摘要:
A vapour emission control system 10 for a bulk liquid chemical tank storage complex, the system includes activated carbon absorption plant 29 having a pair of absorber vessels 35 to which the vapours are delivered by a common delivery duct 40, and from which vapours are received via a common outlet duct 45, and wherein the plant 29 further includes transfer ducts which enable the vessels 35 to be connected in series or parallel.
摘要:
Bei der Aktivkohleeinrichtung ist in einem Gehäuse ein umlaufendes, die Aktivkohle enthaltendes Filtergehäuse (15) angeordnet, das nacheinander eine Adsorbierzone (I), eine Regenerierzone (II) und eine Trocknungszone (III) durchläuft, so daß die Einrichtung im Dauereinsatz bleiben kann.
摘要:
Dispositif de récupération des solvants contenus dans l'air extrait de cabines de peinture, qui comporte un caisson filtrant à charbons actifs pour retenir les solvents, et un système de régénération des charbons actifs par circulation d'air de dilution pendant l'arrêt de l'émission de solvants, ce dispositif étant caractérisé en ce qu'il comporte des moyens de récupération (32) des solvants contenus dans le mélange air + solvants sortant des caissons filtrants, assurant un rejet d'air épuré dans l'atmosphère.
