Gas emission treatment device used in propionic acid preparation process

Abstract

The invention relates to the technical field of propionic acid preparation, and discloses a gas emission treatment device used in a propionic acid preparation process. The device comprises a fixed cylinder, the bottom of the fixed cylinder is fixedly connected with a collection box and a gas inlet pipe, the top of the fixed cylinder is fixedly connected with an exhaust pipe, the inner bottom wall of the fixed cylinder is fixedly connected with an arc-shaped bulge, an agent storage box is fixedly connected to the interior of the fixed cylinder, the agent storage box is sleeved with a rotating cylinder, six annularly-arranged adsorption sponges are fixedly connected to the exterior of the rotating cylinder, six annularly-arranged magnetic plates are fixedly connected to the inner side wall of the rotating cylinder, and six annularly-arranged agent inlet holes are formed in the inner side wall of the rotating cylinder. When gas moves upwards to penetrate through the adsorption sponge on the right side, harmful gas reacts with a reactant in the adsorption sponge to be absorbed, water vapor in the gas is also absorbed by the adsorption sponge, and the rest of gas penetrates through the adsorption sponge to be exhausted from the exhaust pipe, so that the effect of treating the harmful gas in the gas is achieved.

Description

technical field [0001] The invention relates to the technical field of propionic acid preparation, in particular to a gas emission treatment device used in the preparation process of propionic acid. Background technique [0002] Propionic acid, also known as initial oleic acid, is a three-carbon carboxylic acid, a short-chain saturated fatty acid. Pure propionic acid is a colorless, corrosive liquid with a pungent odor. Propionic acid is mainly used as a food preservative and anti-mold It can also be used as an inhibitor of viscous substances such as beer, a nitrocellulose solvent and a plasticizer, and can also be used in the preparation of nickel plating solutions, the preparation of food spices, and the manufacture of medicines, pesticides, and antifungal agents. [0003] The preparation of propionic acid needs to heat and evaporate the liquid raw material. During the heating process, the raw material will generate gas, and some of the gas will pollute the environment whe...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a gas emission treatment device used in the preparation of propionic acid, which has the advantage of absorbing the harmful gas generated during the preparation of propionic acid, and solves the problem that the liquid raw materials need to be processed during the preparation of propionic acid. Heating and evaporation, the raw materials will generate gas during the heating process, and some of the gas will be released into the air, which will cause environmental pollution.
