Short-process two-stage ammonia absorption and purification device

The utility model relates to a short-process two-stage ammonia absorption and purification device which comprises an evaporation and purification box, a heating layer, a separation layer and a condensation layer are sequentially arranged in the box body from bottom to top, and a first pipeline and a second pipeline are arranged at the top of the box body; the gas-liquid separation module comprises a gas-liquid diverter and a separation layer arranged in the evaporation purification box; the valve module is used for controlling input of gas and fluid in the evaporation purification box; the detection module; the control module receives a feedback signal of the detection module and then operates an instruction; and the ammonia water tank is communicated with the output end of the evaporation purification box. By the adoption of the technical scheme, the short-process two-stage ammonia absorption and purification device is simple in structure, the purification process of waste ammonia water is shortened, laborat
