| titleOfInvention | Preparation system for preparing calcium and magnesium compound fertilizer by decomposing phosphorus tailings with nitric acid |
| abstract | A preparation system for preparing calcium-magnesium compound fertilizer from nitric acid decomposes phosphorus tailings, comprising a phosphorus tailings acid hydrolysis tank, the phosphorus tailings acid hydrolysis tank is used for feeding phosphorus tailings and phosphoric acid, and the output end of the phosphorus tailings acid hydrolysis tank passes through The pipeline is connected to the filter, the filter is used to filter out acid insoluble substances, the filtrate of the filter is used to pass into the filtrate tank, the output end of the filtrate tank is connected to the input end of the reactor through the pipeline, and the other input end of the reactor is connected to the liquid ammonia system Connection, the output end of the reactor is connected with the compound fertilizer granulation system through a pipeline, and the input end of the compound fertilizer granulation system is used for feeding phosphate fertilizer and potash fertilizer. The system utilizes phosphorus tailings, saves resources, reduces environmental pollution, and the calcium and magnesium of the prepared compound fertilizer are more easily absorbed by plants, which promotes plant growth, especially for plants that require large amounts of calcium and magnesium. |
