The design main content has the design general remarks, the technological design and the non- technological design three parts. The general remarks partial in detail introduced the product specification, the raw material selection, the entire factory produce the route the choice as well as the phosphoric acid lives the midproduction importance in the national. The craft are partial mainly is analyzes the aqueous method phosphoric acid production the basic principle, the crystal process, the production method choice, the craft condition determination, the equipment choice, Material balance , the thermal graduated arm calculates with the equipment computation. The non- craft partial mainly introduced the ground water pollution, the air pollution and the waste gas pollution processing situation. According to designed has drawn the aqueous method sulfuric acid workshop production flow chart.Key word: Aqueous method phosphoric acid, technological design, process design目 录第一章绪论61.1湿法磷酸生产的发展6第二章概述62.2磷酸的性质62.2.1磷酸的物理性质62.2.2磷酸的化学性质62.3硫酸6
