High-temperature waste gas treatment system for polyamide production equipment

The invention discloses a high-temperature waste gas treatment system for polyamide production equipment. The high-temperature waste gas treatment system comprises a high-temperature waste gas treatment unit and a waste liquid treatment system. The high-temperature waste gas treatment unit comprises a vent tank, a second tube-bundle condenser, a coil, a refrigerating system and a waste liquid collector. The waste liquid treatment system comprises a settling pond, an oil trap, an anaerobic tank, a neutralizing tank, a flotation tank, a primary settling tank, an aerobic tank, and a secondary settling tank, which are arranged in order from front to rear according to a process flow. An inlet of the settling tank is communicated with a liquid outlet of a waste liquid collection tank. The high-temperature waste gas treatment system has the advantages such as high purifying efficiency, good purifying effect and double condensation availability.
