Device and method for treating lactone synthetic perfume organic waste gas through combined process

Abstract

The invention discloses a device and method for treating lactone synthetic perfume organic waste gas through a combined process, and belongs to the technical field of organic waste gas treatment.The device comprises an air feeder, a deep condenser is arranged on one side of the air feeder, a waste gas main inlet is formed in one side of the deep condenser, and the output end of the air feeder communicates with the waste gas main inlet; the condensate temporary storage tank is connected with the deep condenser through a pump; the medium degradation tower is connected with a condensed tail gas outlet of the deep condenser through a pipeline; a medium degradation first spraying pipe and a medium degradation second spraying pipe are arranged on the medium degradation tower, and the medium degradation tower is connected with a water tank at the bottom of the medium degradation tower through a medium circulating pump. After the lactone perfume organic waste gas is subjected to deep condensation, medium degradation, organic solvent absorption, alkali liquor spraying and activated carbon fiber adsorption treatment, the factory odor concentration and organized waste gas emission can meet the up-to-standard emission requirements.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment, in particular to a device and a method for processing organic waste gas of lactone synthetic fragrance by a combined process. Background technique [0002] VOCs are short for Volatile Organic Compounds. Volatile organic compounds are emitted into the atmosphere and undergo photochemical reactions under certain conditions to produce secondary pollutants such as fine particles and ozone, which are an important cause of air pollution such as haze. After sulfur dioxide and nitrogen oxides, another important air pollution indicator, the fragrance of fragrance products produced by synthetic fragrance enterprises has industry specificity, characteristic fragrance, long fragrance retention time, and relatively high threshold. Many fragrance products have high concentration When it is high, it shows a foul odor. [0003] The main pollutants of organic waste gas in the production proce...

AI Technical Summary

Problems solved by technology

[0005] Among the above-mentioned organic waste gas treatment methods, the adsorption treatment method has simple process, convenient management, and low operating costs, but it is prone to secondary pollution, and the treatment efficiency is limited due to untimely adsorption. The combustion treatment method has high input costs, high operating costs, and easy equipment. Corrosion, etc., the treatment efficiency of biological treatment depends on the residence time, resulting in a large footprint, easy to poison and death of microorganisms, etc.

A single treatment method cannot effectively solve and treat the organic waste gas in the production process of lactone synthetic perfume, and it is necessary to provide an organic waste gas treatment device and method that can effectively improve the purification efficiency and eliminate secondary pollution
