The invention provides a device used for generating ammonia gas based on solid urea measurement and applied to automobile exhaust denitration, and belongs to the technical field of denitration in the motor vehicle exhaust treating process. The device comprises a urea storage tank (1), a first controllable rotating motor (2), a solid urea conductor (3), a molten urea reactor (4), a molten urea centrifugal barrel (5), a high-frequency alternating-current coil (6) and a second controllable rotating motor (7). With the adoption of the device, the problems that the device cannot be resistant to the low temperature when a method for generating ammonia gas by a urea solution is adopted in the prior art of the field and the safety is not sufficient when an ammonia gas tank is directly used are solved; and further, compared with a conventional device for generating ammonia gas by solid urea, the device has the advantages of accurate measurement, high practicability, lower energy consumption, quick ...
