Description

Technical Field

[0001] The utility model relates to the technical field of waste gas absorption devices, in particular to a waste gas absorption device for preparing galvanic acid ester. Background Art

[0002] Glycol ester is a chemical substance with the molecular formula C10H18O3. It is also known as allyl isopentyl acetate and its CAS registration number is 67634-00-8. Glycol ester is a colorless, transparent liquid with a strong fruity, green, garnet and pineapple aroma. This aroma property makes Glycol ester very useful in the formulation of daily chemical fragrances, adding a modern touch to the fragrances.

[0003] Waste gas is generated during the preparation of galvanized ester. The production of galvanized ester is a process involving chemical reactions, which are usually accompanied by the generation of by-products such as waste gas, wastewater and solid waste. These waste gases contain harmful chemicals and pollute the environment. In order to prevent the waste gas from polluting the environment, it is necessary to use activated carbon to adsorb it. When the activated carbon is saturated with adsorption, it is necessary to replace it with new activated carbon. However, when replacing the activated carbon, the emission of waste gas needs to be stopped, which causes the preparation work to be suspended. The suspension time of the work changes with the replacement time, which affects the efficiency of the preparation work. Therefore, a waste gas absorption device for the preparation of galvanized ester is proposed. Utility Model Content
