The invention relates to the technical field of ammonia synthesis, and discloses a low-consumption conversion ammonia-containing wastewater separation and treatment device which comprises an ammonia washing tower, a comprehensive flash evaporator, an alternating-current cooler, a stripping tower and a tail gas separation tank. The first ammonia washing tower and the second ammonia washing tower are arranged in parallel, bottom outlets are communicated to the comprehensive flash evaporator through a seventh adjusting valve and an eighth adjusting valve, high-pressure ammonia-containing condensate is throttled and depressurized, and physical turbulent flow is induced in the flash evaporator to accelerate desorption of acid gas. And the flash evaporation lower liquid enters the cold side of the alternating current cooler through a condensate pipeline, absorbs heat from a gas phase at the top of the stripping tower for preheating, and then enters the stripping tower for countercurrent deep stripping. Purified condensate generated at the bottom of the stripping tower is discharged out of the system, and a tower top gas phase is fed into a tail gas separation tank for gas-liquid separation after being subjected to heat exchange by an alternating-current cooler and cooling by a circulating water cooler. Through high-pressure flash evaporation pretreatment and an internal thermal coupling mechanism, the saturated steam consumption of a steam stripping section is reduced, and the problems of crystal blockage and equipment corrosion are solved.

This utility model provides a lightweight, high-heat-exchange-capacity internal and external coil heat exchanger, relating to the field of heat exchanger technology. It addresses the problem that the contact distance between the inner side of the flow channel and the exhaust gas is the greatest, and the outer side of the flow channel obstructs the contact, making it difficult to fully contact and exchange heat with the high-temperature exhaust gas. This results in poor overall heat exchange uniformity of the cold liquid, ultimately causing the exhaust gas to still carry a large amount of residual heat. The device includes: an outer heat exchange cylinder; a return pipe fixedly connected to the external joint of the outer heat exchange cylinder; another set of the connecting joints connected to an external exhaust pipe; a return heat exchange pipe inside the cold flow tube; and an external exhaust inner cylinder fixedly connected to the inside of the outer heat exchange cylinder.
