Embodiment 1～8

[0016] A polyester production plant emits waste gas, and its waste gas discharge volume is 1000-10000m 3 / h; Exhaust gas contains acetaldehyde, paraldehyde, ethylene glycol, 2-methyl-1,3-dioxolane and other substances, of which acetaldehyde and 2-methyl-1,3-diox The pentane ring is the main one, and its total hydrocarbons range from 3000 to 20000 μl / l. Use a fan to draw the exhaust gas out, and after passing through the absorption homogenizer, ethylene glycol is completely absorbed, and acetaldehyde and 2-methyl-1,3-dioxolane are homogenized in concentration; after preheating to a certain temperature, It enters the catalytic combustion reactor and is completely oxidized and discharged under the action of the catalyst. Table 1 is the operating conditions and treatment results of Examples 1 to 8, wherein the catalytic combustion catalyst in Examples 1 to 4 is a honeycomb catalyst containing Pt 0.26wt%, Pd 0.13wt%, and the catalytic combustion catalyst in Examples 5 to 8 It is ...

Embodiment 9

[0018] This example illustrates the homogenization effect of the homogenizing absorber, the homogenization results are shown in figure 1 , the homogenization effect is obvious.

Abstract

The present invention relates to the method of purifying waste gas containing water soluble organism, and is especially the method of purifying waste gas produced in polyester production. The waste gas produced in polyester production is first made to pass through adsorption homogenizer containing water and then catalytically combusting treated. In the adsorption homogenizer, the high boiling point organism, such as glycol, is absorbed, while the other organic components, such as acetaldehyde, is stabilized and homogenized. The said process can eliminate the high boiling point organism from polyester waste gas effectively to eliminate hidden trouble in safety and homogenize the other components for stable catalytic combustion.

Description

1. Technical field [0001] The invention relates to a method for purifying and treating waste gas containing water-soluble organic matter, more specifically, to a kind of polyester production process discharge containing acetaldehyde, 2-methyl-1,3-dioxolane, ethylene glycol and Purification treatment method of other organic component waste gas. 2. Background technology [0002] The emissions from the polyester production process mainly contain acetaldehyde, 2-methyl-1,3-dioxolane, ethylene glycol, and other low-molecular oxygen-containing organic compounds such as aldehydes, ketones, alcohols, acids, esters, and ethers. The exhaust gas of organic matter has a high concentration of organic matter and has a strong bad smell. If it is not purified, it will pollute the surrounding environment and violate the national environmental protection regulations. [0003] The exhaust gas emitted during the early polyester production process was mostly treated by the method of combustion ...
