Technical Field
[0001] This utility model belongs to the field of separation equipment technology, specifically a separation equipment for the production and preparation of ultrapure ammonia. Background Technology
[0002] Ultrapure ammonia, as a high-purity chemical, is widely used in high-tech fields such as electronics, semiconductors, and photovoltaics. Its purity and quality requirements are extremely high, needing to reach 99.999% or higher. Traditional preparation methods struggle to meet the stringent control requirements for trace impurities such as moisture, oxides, and metal ions, making efficient separation equipment crucial. Current technologies include adsorption, membrane separation, cryogenic distillation, and composite technologies. These methods achieve efficient separation through specialized adsorbents, polymer membranes, and precise temperature control, while also developing towards highly selective materials, automated intelligent control, and environmental friendliness to improve separation efficiency, reduce energy consumption, and minimize pollution. With the rapid development of 5G, artificial intelligence, and new energy fields, the demand for electronic-grade ultrapure ammonia is increasing. Technological innovation in separation equipment not only helps meet high-purity requirements but also significantly reduces production costs and improves resource utilization, making its development of crucial equipment for the development of high-tech industries.
[0003] However, in actual use of existing solutions, the mixed ammonia gas and the separation medium are directly fed into the separation tower simultaneously for condensation and moisture separation. This may result in low separation efficiency, residual ammonia gas, and increased environmental pollution. Uneven gas-liquid flow within the tower may cause problems such as liquid accumulation and blockage, affecting the stable operation of the equipment. The inefficient condensation process also increases energy consumption, causes corrosion and scaling, reduces equipment lifespan, and increases maintenance costs.
[0004] Therefore, this utility model provides a separation device for the production and preparation of ultrapure ammonia. Utility Model Content
