TL;DR: In this article, a circulating treatment regeneration process of an oil-containing VOCs exhaust gas spray absorption medium is described. And the process utilizes a spray tower, a dissolved air flotation cell, an electrolytic cell, a clean water tank and a sludge pool.
Abstract: The invention discloses a circulating treatment regeneration process of an oil-containing VOCs exhaust gas spray absorption medium. The process utilizes a spray tower, a dissolved air flotation cell,an electrolytic cell, a clean water tank and a sludge pool. The dissolved air flotation cell is arranged below the spray tower. The top side of the dissolved gas flotation cell is connected to the sludge pool. The bottom of the dissolved air flotation cell is connected with the electrolytic cell. The electrolytic cell is connected to the clear water tank. The clear water tank is connected to the spray tower. The process can produce initial ecological Fe and atom H through an electrochemical reaction under oxygenation conditions and the Fe and atom H have high chemical activity, can change the structures and characteristics of many organic substances, can realize organic matter chain breaking and ring opening, and can oxygenate and prevent iron scrapping in aeration. Fe generated by Fe oxidation is gradually hydrolyzed to form a Fe(OH)3 colloidal flocculant with high degree of polymerization, which can effectively adsorb and condensate the pollutants in the spray mediumto enhance the purification effect.
