The invention discloses a VOC normal-temperature condensation
treatment system and a method utilizing static activity of
activated carbon, and relates to the technical field of
industrial emission VOCs treatment. The VOC normal-temperature condensation
treatment system comprises a VOCs pretreatment
system, a
desorption condensation
system, an auxiliary adsorption
bed C, an adsorption
bed A and anadsorption
bed B; the adsorption beds A and B are connected with an adsorption fan through an adsorption air
inlet valve; the adsorption fan is connected with the VOCs pretreatment
system; the adsorption beds A and B are connected with the
atmosphere through adsorption air outlet valves; the adsorption beds A and B are in serial closed connection through series valves Ab and Ba; and two ends of the adsorption bed A, the adsorption bed B and the auxiliary adsorption bed C are respectively connected with two ends of a
desorption condensation system through
desorption condensation valves. By adopting the treatment method of the system, the static activity of the
activated carbon is fully utilized, the cost of the
activated carbon is reduced, the service life is prolonged, and the recovered
organic solvent is higher in purity and high in
recovery efficiency; and a 2 + 1 mode is adopted, so that the control strategy is simpler, and the operation is more reliable.
