The invention discloses a novel device and a technology for purifying maleic anhydride by a novel solvent absorption method. The device comprises an absorption tower, a rectifying tower, an extractionpremixing tank and a centrifugal extractor. A reaction gas is cooled, and then reversely contacts with an absorbent in the absorption tower, maleic anhydride absorbed rich oil is extracted from the tower bottom, enters the rectifying tower, and is desorbed, gas-phase light components are extracted from the tower top of the rectifying tower, the maleic anhydride product meeting the product purityrequirement is extracted from the side line, and lean oil almost containing no maleic anhydride is extracted from the tower bottom; and lean oil extracted from the tower bottom of the rectifying toweris divided into three streams which respectively enter the tower top of the absorption tower, a circulating material inlet at the middle lower part of the absorption tower and the extractor, tar in the lean oil entering the extractor is removed through extraction, and the lean oil returns into the absorption tower again in order to effectively ensure the purity requirement of the absorbent. The novel device and the technology for purifying maleic anhydride through the solvent absorption method effectively guarantee that the purity of maleic anhydride reach 99.99 wt%, the yield of maleic anhydride reaches 98% or above and the cyclic utilization rate of the absorbent reach 99.8% or above.
