The invention belongs to the technical field of liquid ammonia security treatment, and particularly relates to an automatic liquid-ammonia consumption transformation system. The automatic liquid-ammonia consumption transformation system comprises a consumption device and is characterized in that a main heat exchanger is arranged in the consumption device, a liquid ammonia inlet pipe and a liquid ammonia outlet pipe are connected to the top of the main heat exchanger, a chilled-water feed pipe is connected to the lower portion of the main heat exchanger, a liquid ammonia inlet adjusting valve is arranged on the liquid ammonia inlet pipe, a consumption water inlet adjusting valve is arranged on the consumption water inlet pipe, and an automatic chilled-water inlet switch valve is arranged on the chilled-water feed pipe. The automatic liquid-ammonia consumption transformation system has the advantages that the spiral plate type heat exchanger is arranged on the consumption device, so that the entire device is small in space occupation, low in investment and high in efficiency; ammonia outlet temperature and concentration can be adjusted, so that the system is widely applicable and highly practical; entire liquid ammonia consumption can be automatically completed, simpleness in operation is achieved, and security and reliability is high.
Description
(1) Technical field [0001] The invention belongs to the technical field of safe treatment of liquid ammonia, in particular to an automatic liquid ammonia consumption and transformation system. (2) Background technology [0002] Ammonia is a widely used substance in various phases. Ammonia is very soluble in water to form ammonia water. Ammonia is an important chemical raw material and a commonly used reagent in chemical experiments. Ammonia water is a colorless and transparent liquid with a special strong irritating odor. Ammonia water is alkaline, but high-temperature ammonia solution is extremely unstable, and ammonia gas dissolved in water will overflow from the ammonia water, making the concentration of ammonia water greatly increased. reduce. [0003] Liquid ammonia has high storage requirements due to safety reasons, and corresponding liquid ammonia emergency treatment devices must be equipped to convert liquid ammonia into ammonia water. The mixing process of liqui...
