Problems solved by technology

[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 t

Example Embodiment

[0046] First, see image 3 As shown, in the first embodiment of the present invention, a first condenser 31a is arranged inside an exhaust gas flow channel 30, and a sprinkler 32 is arranged at the downstream end of the first condenser 31a. 31a separates most of the water-soluble volatile organic compounds, and then the sprinkler 32 sprays water mist on the passing exhaust gas flow, so that the residual water-soluble volatile organic compounds are separated by the adsorption of water droplets.

[0047] Next, see Figure 4 As shown, in the second embodiment of the present invention, a second condenser 31b is further disposed at the downstream end of the sprinkler 32, and the first condenser 31a and the second condenser 31b can be condensing coils, plate condensers , a shell-and-tube condenser or a fin-type condenser; therefore, due to the effect of spraying water mist by the sprinkler 32, the exhaust gas flow entering the second condenser 31b is heated and humidified, and the ...

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...
