Abstract
The invention relates to the technical field of liquid ammonia production, and concretely relates to an environmentally-friendly liquid ammonia dilution system and a production method thereof. The liquid ammonia dilution system comprises a cooling tower, a circulating water tank, a water treatment device, a tail gas absorber, an ammonia water storage tank and a liquid ammonia storage tank, a liquid ammonia diluter comprises a body with a tower structure, a reaction chamber for diluting liquid ammonia is arranged at the middle part of the body, a plate heat exchanger for cooling is arranged outside the reaction chamber, and a circulating water outlet tube, a circulating water inlet tube and a liquid ammonia inlet tube are arranged at the middle part of the body; and liquid ammonia in the liquid ammonia storage tank enters the liquid ammonia diluter through the liquid ammonia outlet tube, soft water in the circulating water tank is pumped into the liquid ammonia diluter by a soft water pump through a soft water inlet tube, the liquid ammonia is diluted with the soft water in the reaction chamber to form ammonia water with a certain concentration, and the ammonia water is conveyed into the ammonia water storage tank through an ammonia water outlet tube. The invention also provides the production method of the environmentally-friendly liquid ammonia dilution system. The system solves the problem of ammonia gas leakage in the dilution process of liquid ammonia, and reduces environmental pollution.
Description
technical field [0001] The patent of the invention relates to the technical field of liquid ammonia production, in particular to an environment-friendly liquid ammonia dilution system and a production method thereof. Background technique [0002] Liquid ammonia is an important industrial raw material, widely used in pharmaceuticals, oil refining, synthetic fibers, synthetic resins, refrigeration, metallurgy, etc. In industrial production, liquid ammonia is generally dissolved in water to make industrial ammonia water. The structural form of the traditional ammonia water preparation device is: a stainless steel coil with a liquid outlet hole is placed at the bottom of the ammonia water configuration tank, and the liquid ammonia is slowly entered into the tank filled with water by the liquid ammonia pump and valve control. Slowly dissolve in water to form ammonium hydroxide solution. The existing ammonia water preparation device has the following defects: a large amount of a...
