Activated charcoal equipment for exhaust air purification with simultaneous recovery of the solvent vapors. Concentrator equipment for converting large volumes of air with a low solvent concentration to low volumes of air with a high concentration of solvents, enabling a 10 to 1 size reducing of the main exhaust purification equipment running on adsorption or oxidation technology.The high technological standards of Rotamill's exhaust air purification systems offer excellent problem solutions. Our activated charcoal equipment represents an elegant and economically efficient concept for the solution of purification challenges.
As polluted air passes through the activated charcoal, solvents are adsorbed and the purified air is released into the atmosphere. Once the activated charcoal is saturated, the desorption phase is automatically started, blowing steam through the charcoal in the reverse direction. The solvents are evaporated by the heat and mix with the steam. The solvent is then separated from the steam and both components are returned to their respective circulatory systems.
Double and in-line plants consist of two or more interconnected adsorption vessels which adsorb and desorb alternately in a continuous system. The functional principle of the concentrators is basically the same as described above, with the addition that the activated charcoal surface rotates continuously so that all processes operate simultaneously. The desorption is achieved by heated air in counterflow, which continues in concentrated form to a subsequent exhaust air purification plant for cleaning.
