This invention discloses an energy-saving ammonium chloride evaporation crystallization system and process.

It also includes a falling film scrubbing tower, a forced circulation scrubbing tower, and a three-stage compressor. The forced circulation secondary steam, after scrubbing, enters the first-stage compressor. The second-effect secondary steam, after scrubbing, bypasses the first-stage compressor and merges at the outlet side of the first-stage compressor. It is then compressed in the second and third stages and reused for the first-effect falling film evaporation and forced circulation evaporation crystallization. This process, by setting the falling film evaporation to double-effect, only compresses the second-effect and forced circulation secondary steam; by using the first-stage compressor to separately increase the temperature rise of the forced circulation secondary steam, compensating for its high boiling point rise, it merges with the second-effect steam and is then compressed in the second and third stages for reuse. Since the boiling point rise in the falling film section is low, the second-effect steam only requires two stages of compression to meet the heat transfer temperature difference. This effectively reduces the amount of gas passing through and power consumption, and improves stability.
