Title:
吸収、脱離及び回収を一体化したＶＯＣｓ回収システム及び方法
Document Type and Number:
Japanese Patent JP7461679
Kind Code:
B2
Abstract:
Disclosed are a VOCs recovery system and method integrating absorption, desorption and recovery. The recovery system comprises a washing unit, which is connected to a self-coupling pre-cooling unit and is used for washing VOCs inlet gas; the self-coupling pre-cooling unit, which is connected to a low-temperature absorption unit and is used for condensing the washed VOCs gas; the low-temperature absorption unit, which is connected to a high-temperature desorption unit by means of a heat exchanger II (20) and is used for absorbing the condensed VOCs gas; the high-temperature desorption unit, which is connected to a low-temperature recovery unit by means of a heat exchanger III (24) and is used for desorbing the VOCs gas subjected to low-temperature absorption; and the low-temperature recovery unit, which is connected to the low-temperature absorption unit and is used for recovering liquefied VOCs and conveying un-liquefied VOCs to the low-temperature absorption unit again for treatment. Not only is a high amount of energy saved, the cyclic utilization of absorption liquid is also realized.
