Summary:The invention discloses a system and a method for utilizing heat energy of an oximation device. The system comprises a TBA (Tert Butyl Alcohol) recovery tower feeding heat energy recoverer, a TBA recovery tower, a valve 1, a valve 2, an oximation wastewater steam stripping evaporator, a methylbenzene oximate heat energy recoverer, a first rectification tower, a TBA recovery tower gas-phase condenser, a TBA reflux tank, a wastewater steam condenser, a mechanical vacuum pump and a condensed wastewater recovery tank, wherein the oximation wastewater steam stripping evaporator and the methylbenzene oximate heat energy recoverer are in parallel and serial arrangement. According to the system and the method for utilizing the heat energy of the oximation device, disclosed by the invention, heat of high-temperature condensate during a production process of caprolactam can be recovered through the TBA recovery tower feeding heat energy recoverer, and heat of gas-phase steam flowing out of the TBA recovery tower can be
