Ammonium nitrate production device and method

The invention provides an ammonium nitrate production device and method. The device mainly comprises a reactor, a washing tower, a condenser, a water cooler, a steam compressor, a flash evaporator, anevaporator and the like, reflux liquid condensate is used for washing operation, ammonia and acid content in the liquid condensate is reduced, the liquid condensate can be fully used as supplementingwater of circulating water, and the condenser is used for generating low-pressure steam, the low-pressure steam is pressurized through the compressor, low-level energy heat is converted into high-level energy heat, comprehensive utilization of energy in the production process is facilitated, and the energy value in the production process is improved. Meanwhile, a steam by-production method is utilized, the reaction heat is reasonably utilized, the circulating water consumption required by cooling and the running energy of the device are further reduced, and the purposes of energy conservationand emission reduction are
