Abstract

The invention relates to an organic exhaust gas recovery method, especially to an organic exhaust gas recovery method of continuous adsorption and rectification. The method is sent the organic exhaust gas in to the activated carbon fibre absorber, and the resolution steam enters a three way auto valve directly where the temperature sensor is mounted and which is controlled by the temperature sensor. The resolution steam enters rectification tower directly to be rectified when the temperature is higher than 100 degree C, and when the temperature is lower than 100 degree C, the resolution steam with noncondensing air is condensed into a condensator, wherein the condensate is continuously pumped into rectification tower and the noncondensing air is re-absorbed back to the absorber. The invention has the advantage of a simple process and a convenient operation, also be capable of continuous adsorption and rectification, has a high rate of recovery in organic solvent, and saves energy sources.

Description

technical field

[0001] The invention relates to a method for recovering organic waste gas, in particular to a method for recovering organic waste gas by continuous adsorption and rectification. Background technique

[0002] In the printing, coating and other industries, printing inks and glues contain a large amount of organic solvents. After printing and coating, the printing paper and coating are generally dried in an oven, the paper or coating is transported to the drying oven, and then the hot air is sent to the dryer by the blower for drying. During the drying process, the organic solvent generates a large amount of organic waste gas after being heated by the oven. For these organic waste gases, the activated carbon fiber adsorber is generally used to absorb and recover them and then desorb them. During desorption, water vapor is used for desorption, and the desorption steam is cooled by a condenser to form an aqueous solution, and the aqueous solution enters a rectif...
