Problems solved by technology

The common lipid waste gas treatment scheme adopts activated carbon adsorption or spray tower washing process. The adsorption efficiency of activated carbon is limited, and it is easy to produce saturation, which cannot fundamentally remove the odor and achieve the treatment effect; the spray tower washing process is to introduce the waste gas into oxidative solution, but this technology requires a certain space and is difficult to implement in actual production. In addition, the strong oxidizing properties of oxidants often cause physical harm to workers

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of lipid waste gas treatment, in particular to a kind of odor absorption of lipid waste gas [0002] Disclosed are an odor-absorbing board loaded with an absorbent, a preparation method of the odor-absorbing board, a dry deodorization process using the odor-absorbing board and equipment thereof. Background technique [0003] Lipid waste gas pollution is a relatively common type in production and life. For example, in the thin plate rolling mill of Baosteel Group, an emulsion is used in the steel rolling process. The working environment will cause pollution, which will pose a threat to the health of workers in the long run; and for example, when cooking in the kitchen in the catering industry, cooking and grilling will bring a lot of oily smoke and peculiar smell. If it is not treated, it will pollute the atmosphere. . [0004] Lipid waste gas treatment is the most difficult technology in industrial waste g...
