NOVELTY - Device for processing urea waste liquor, comprises a hydrolysis feeding pump (1), a hydrolysis heat exchanger (2), and a gas stripping hydrolysis tower (3). The urea waste liquor is connected to the hydrolysis feeding pump inlet via a pipeline. The hydrolysis feeding pump outlet is connected with the first inlet (31) of the gas stripping hydrolysis tower and the hydrolysis heat exchanger via a pipeline. The bottom outlet (33) of the gas stripping hydrolysis tower is connected with the external emission waste liquor pipe through a pipeline via the hydrolysis heat exchanger.    USE - The device is useful for processing urea waste liquor.    ADVANTAGE - The device: simplifies the production process; reduces apparatus investment; avoids the use of static apparatus (reflux condenser, warm water cooler and reflux groove) and operation devices (water pump and reflux pump); reduces the amount of partial pipelines, valves and instruments, and is suitable for various urea production processes e.g. carbon dioxide gas stripping method and ammonia gas stripping method.    DETAILED DESCRIPTION - Device for processing urea waste liquor comprises a hydrolysis feeding pump (1), a hydrolysis heat exchanger (2), and a gas stripping hydrolysis tower (3). The urea waste liquor is connected to the hydrolysis feeding pump inlet via a pipeline. The hydrolysis feeding pump outlet is connected with the first inlet (31) of the gas stripping hydrolysis tower and the hydrolysis heat exchanger via a pipeline.
