Relating to the technical field of wet metallurgy, the invention discloses a high temperature ammonia recovery device. The device includes an APT crystallization kettle, a first plate heat exchanger and a hydraulic jet pump that are connected in series in order, a first pipeline between the APT crystallization kettle and the first plate heat exchanger is equipped with a second valve, a main exhaust pipe, a tubular heat exchanger, an exhaust fan, and a leaching tower are connected in series in order, the upper part of the APT crystallization kettle is connected to the main exhaust pipe, a second pipeline is provided with a first valve, and the hydraulic jet pump is connected to the mid-rear end of the main exhaust pipe. The hydraulic jet pump, a recovered ammonia water storage tank, a second plate heat exchanger and a second circulation pump are connected to each other in series to form a loop, and a first circulating pump is in circulating connection with the middle and upper part of the leaching tower through a water pipe. The device is provided with 3 condensed ammonia water recovery ports, and the recovery efficiency can reach 98%. The device is provided with 3 cooling equipment, and can effectively avoid ammonia escaping from the recovered ammonia water due to high temperature. The device can recover a high amount of ammonia water every day, and saves cost.
