SINGLE PASS PATTERN DECOMPOSING AND ELIMINATING SYSTEM OF FORMALDEHYDE AFTER FUMIGATION

PROBLEM TO BE SOLVED: To provide a single-path type decomposing and eliminating system of formaldehyde after fumigation in which safely and efficiently decomposing and eliminating formaldehyde. SOLUTION: Contacting time with a formaldehyde decomposing catalyzer is increased to enhance the decomposing effect of the catalyzer by reducing the air volume of the processing air introduced into a formaldehyde decomposing device before the predetermined time passes, when an air conditioner introducing outer air into a chamber for formaldehyde fumigation, the chamber for form aldehyde fumigation where formaldehyde fumigation process is executed, and a formaldehyde decomposing device where formaldehyde decomposing process is executed to the processing air discharged from the chamber for form aldehyde fumigation and which discharges processed air into the air are connected in series and the above processed air is introduced into the formaldehyde decomposing air.
