DEODORIZATION FILTER AND REGENERATION METHOD OF DEODORIZATION FILTER

摘要

PPROBLEM TO BE SOLVED: To provide a deodorization filter excellent in the deodorization capacity of neutral gases such as aldehyde; to regenerate the deodorization filter whose performance is lowered by a simple method; and to provide the deodorization filter having a long service life. PSOLUTION: For the deodorization filter 1, the deodorization filter 2 for acidic gases and for basic gases formed of a combined deodorant for which at least two or more porous absorbents are combined is arranged on the upstream side of the flow of a gas, and the deodorization filter 3 for the neutral gases formed of a porous absorbent to which an impregnating agent for chemically absorbing the neutral gas is impregnated is arranged on the downstream side.
