Abstract
One objective of the present invention is to provide a method and a device for concentrating volatile chemical materials (such as water soluble solvent) with a boiling point higher than water from an exhaust, in which volatile chemical matters are substituted by steam in order to be effectively recycled, while the exhaust is purified. Another objective of the present invention is to provide a method and a device, in which thermal energy in a high temperature (100 DEG C to 120 DEG C) exhaust generally discharged from a process for producing a lithium ion battery is recycled by evaporating water introduced from the outside so that volatile water soluble chemical matters having boiling points higher than water in the exhaust are condensed. That is, a component in the exhaust is substituted by water. Thus, the component can be effectively recovered while the exhaust is purified by the absorption by the replenished water at a lower temperature. A third objective of the present invention is to provide a method and a device, in which a powder containing active carbon etc. is used to absorb chemical matters (e.g. dioxin, etc.) contained in an exhaust in order to purify the exhaust. A method and a device for concentrating matters having boiling points higher than water from exhaust are characterized in that: a tower plate has a structure where a gas can not go through the tower plate without first goes through the water exists in the tower plate. An exhaust containing matter(s) having a boiling point higher than water is introduced into the lower part of a multilayered distillation tower multi-sectionally installed with the tower plate or a packing tower packed with a hydrophilic packing; and on the other end, water is supplied from the top part of the tower. So that the matter(s) having a boiling point higher than water is concentrated at the lower part of the tower due to a gas-liquid equilibrium relationship between the exhaust and water; and the matter(s) remained in the exhaust is further transferred to water at the top part of the tower.
