Embodiment 2

[0018] The present embodiment is made of 100% soybean oil methyl ester by mass percentage. Transfer 100g of the absorption liquid to the bubbling absorber, add an appropriate amount of ethyl acetate to the exhaust gas generator and place it in a constant temperature water bath at 45°C, use a small pump to supply air under positive pressure, and the gas flow rate is about 2.5L / min. The air is divided into two branches, one of which is used as dilution gas, and the other enters the waste gas generator and brings out ethyl acetate gas. By controlling the flow ratio of the two air branches, the simulated waste gas entering the bubbling absorber is realized. The concentration of ethyl acetate in the medium is about 5800ppm, and the simulated exhaust gas parameters are: the target pollutant is ethyl acetate, its concentration is about 5800ppm, the simulated exhaust gas flow rate is about 2.5L / min, and the simulated exhaust gas temperature is about 45°C.

Embodiment 4

[0024] The present embodiment is made of 100% soybean oil methyl ester by mass percentage. Transfer 100g of the absorption liquid to the bubbling absorber, add an appropriate amount of ethyl acetate to the waste gas generator and place it in a constant temperature water bath at 45°C, use a small pump to supply air under positive pressure, the gas flow rate is about 5L / min, and the air It is divided into two branches, one of which is used as dilution gas, and the other enters the exhaust gas generator and brings out ethyl acetate gas. By controlling the flow ratio of the two air branches, the simulated exhaust gas entering the bubbling absorber is realized. The concentration of ethyl acetate is about 3000ppm, and the simulated exhaust gas parameters are: the target pollutant is ethyl acetate, its concentration is about 3000ppm, the simulated exhaust gas flow rate is about 5L / min, and the simulated exhaust gas temperature is about 45°C.

Abstract

The invention relates to the technical field of industrial waste gas pollution treatment, in particular to waste gas absorption liquid for volatile organic gas treatment, which is prepared from 100 mass percent of soybean oil methyl ester. The problems that an existing absorption liquid is high in cost, prone to causing secondary pollution, difficult to recycle and the like are solved, the similarintermiscibility principle of substances is utilized, and the solubility of volatile organic gas in the absorption liquid is greatly improved.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas pollution control, in particular to a waste gas absorbing liquid for volatile organic gas treatment. Background technique [0002] In recent years, with the rapid development of petrochemical, pharmaceutical, pesticide, coating, packaging and printing, leather and other industries, more and more volatile organic compounds have been released into the ambient atmosphere, including: benzene, phenol Classes, esters, etc. The discharge of these volatile organic compounds not only causes air pollution, but also greatly affects the growth and development of animals and plants and human health. For example, in addition to the irritating effect on the mucous membranes of the eyes, nose, and throat, inhalation of high concentrations of ethyl acetate can lead to anesthesia or even respiratory paralysis, acute pulmonary edema, liver, and kidney damage. Long-term exposure may cause corneal turbid...
