Volatile organic matter condensing device

Abstract

The invention relates to a volatile organic matter condensing device; a first condenser is disposed inside a waste gas flow channel; a water sprinkler is disposed at the downstream end of the first condenser; most water-soluble volatile organic matter is separated by the first condenser, and then water mist is sprinkled to waste gas flow passing through by the water sprinkler so as to separate residual water-soluble volatile organic matter by using the absorption effect of water drop; a second condenser is further disposed at the downstream end of the water sprinkler. Therefore, the volatile organic matter condensing device is provided which has the effects of improving recovery quality and separation effect of volatile organic matter.

Description

technical field [0001] The invention relates to a method of separating most water-soluble volatile organic compounds by means of an upstream condenser, and then spraying water mist on the passing waste gas flow by a sprinkler, so that the water mist is sprayed on the passing waste gas flow by the sprinkler, so that The condenser at the downstream end condenses more water droplets to absorb water-soluble volatile organic compounds, especially a volatile organic compound condensation device. Background technique [0002] Organic solvents, which are widely used in life and production, easily volatilize into gases at room temperature, so they are also called Volatile Organic Compounds (VOCs), and most VOCs are toxic to the human body and must be disposed of; However, if the waste gas produced by the process contains water-soluble volatile organic compounds with high boiling point and low vapor pressure, it is usually separated by a condensation device first, and then the unsepar...

[0004] Furthermore, if figure 2 As shown, another existing condensing device for separating water-soluble volatile organic compounds from waste gas is provided with a condenser 21 inside a waste gas flow passage 20, and a sprinkler 22 is provided at the upstream end of the condenser 21 ; This is because the effect of separating water-soluble volatile organic compounds, in addition to the condensation capacity of the condenser, is also closely related to the moisture content of the exhaust gas. The high humidity content of the exhaust gas is easy to condense water droplets and absorb water-soluble volatile organic compounds. ; Therefore, it is hoped that the sprinkler 22 will spray water mist on the passing exhaust gas flow to humidify the exhaust gas flow, so that the condenser 21 will condense more water droplets to absorb water-soluble volatile organic matter; however, the water-soluble volatile organic matter separated by the condenser 21 is not only difficult to purify and reuse because of its extremely high water content, but also causes a large amount of waste water to be reprocessed
