The present invention discloses a fat-based waste gas odor absorption agent, an odor absorption plate loading the absorption agent, a preparation method for the odor absorption plate, a dry-method odor removing process achieved by using the odor absorption plate, and dry-method odor removing equipment. According to the present invention, according to the fat-based waste gas odor absorption plate, the oxidizing agent and the catalyst are loaded on the substrate plate, such that the module combination, the carrying and the transporting can be conveniently performed, and the recycling can be achieved after the loading failure; according to the dry-method odor removing process, coarse filtration, electrostatic adsorption, UV light deodorization, catalytic oxidation degreasing deodorization and acid-alkali neutralization are sequentially performed, and the treated fat-based waste gas is changed into the odorless and tasteless gas so as to achieve the safe discharge standard, such that the atmosphere pollution problem caused by the fat-based waste gas is solved; and according to the dry-method odor removing equipment, the catalytic oxidation technology is immobilized on the alumina substrate plate, and the obtained substrate plate is installed on the composite waste gas treatment equipment, such that the treatment difficulty is solved by the dry process, the damage of the strong oxidizing substances on personal can be avoided, and the installation and the maintenance are convenient.
