Description
技术领域technical field
本实用新型涉及烘干系统的技术领域，更具体地说是涉及气流烘干系统的技术领域。The utility model relates to the technical field of drying systems, more specifically to the technical field of airflow drying systems.
背景技术Background technique
饲料级磷酸氢钙常被用作饲料加工中磷、钙的补充剂，由于其中的磷钙比与动物骨骼中的磷钙比最为接近，并且能够全部溶于动物胃酸中，因此饲料级磷酸氢钙是目前国内外公认的最好的饲料矿物添加剂之一。目前，饲料级磷酸氢钙的工艺路线一般为：通过硫酸与磷矿粉反应萃取生成粗磷酸，然后将粗磷酸与碳酸钙进行中和反应制成肥料级磷酸氢钙，同时对粗磷酸进行除杂制取精磷酸，再将精磷酸与石灰乳进行中和反应制成饲料级磷酸氢钙湿料，然后对饲料级磷酸氢钙湿料进行粉碎烘干后制成粉末状饲料级磷酸氢钙。饲料级磷酸氢钙一般采用气流烘干的方式进行烘干，饲料级磷酸氢钙在生产过程中会产生含有二氧化硫等含硫有害气体的尾气，而目前常见的气流烘干设备在对饲料级磷酸氢钙进行烘干后一般是将尾气直接排入大气中，对环境造成了一定污染。而且，目前常见的饲料级磷酸氢钙气流烘干设备一般结构较为复杂，占地面积较大，使用成本较高，安装及维修均不是十分方便。Feed-grade calcium hydrogen phosphate is often used as a supplement for phosphorus and calcium in feed processing. Because the phosphorus-calcium ratio is the closest to that in animal bones, and can be completely dissolved in animal gastric acid, feed-grade hydrogen phosphate Calcium is one of the best feed mineral additives recognized at home and abroad. At present, the process route of feed grade calcium hydrogen phosphate is generally as follows: react and extract crude phosphoric acid with sulfuric acid and phosphate rock powder, then neutralize crude phosphoric acid and calcium carbonate to produce fertilizer grade calcium hydrogen phosphate, and remove crude phosphoric acid at the same time. Miscellaneous production of refined phosphoric acid, and then neutralize the refined phosphoric acid and milk of lime to produce feed-grade calcium hydrogen phosphate wet material, and then grind and dry the feed-grade calcium hydrogen phosphate wet material to produce powdered feed-grade calcium hydrogen phosphate . Feed-grade calcium hydrogen phosphate is generally dried by airflow drying. Feed-grade calcium hydrogenphosphate will produce tail gas containing sulfur dioxide and other sulfur-containing harmful gases during the production process. After the calcium hydrogen is dried, the tail gas is generally discharged directly into the atmosphere, which has caused some pollution to the environment. Moreover, the current common feed-grade calcium hydrogen phosphate airflow drying equipment generally has a relatively complicated structure, a large floor area, high cost of use, and inconvenient installation and maintenance.
