PURPOSE: A gas retreatment apparatus for a prefabricated air booth is provided to maintain a stable gas state and a clean state by oxidizing, decomposing, and absorbing various microorganisms and contaminants in gas by retreating collected gas from the air booth. CONSTITUTION: A gas retreatment apparatus(1) for a prefabricated air booth comprises a tunnel type closure and a blower(12). The tunnel type closure has an inlet path(11a), and an outlet path(11b). In the tunnel type closure, a pretreatment unit(20), a main treatment unit(30), and a post-treatment unit(40) are arranged in order. The pretreatment unit comprises an ozone generating module(21) for mixing ozone into gas injected through the inlet path. The main treatment unit oxidizes and decomposes the ozone-mixed gas through a plasma reaction layer(31), and a photocatalyst filter layer(33). The plasma reaction layer has a plurality of arc generators(32), and generates plasma-activated particle and ultraviolet ray. The post-treatment unit removes residual ozone in the untreated gas. The post-treatment unit comprises an UV generating module(41), and an adsorptive catalyst filter layer(42). |
