| titleOfInvention | A pretreatment equipment and purification device for removing carbon from nitric acid industrial tail gas and extracting N2O |
| abstract | The utility model relates to the technical field of chemical substance recovery, and provides a pretreatment device and a purification device for removing carbon from nitric acid industrial tail gas and extracting N2O . The pretreatment equipment includes a water washing tower, a buffer tank, a first compression cooling device, a dryer, and a pressure swing adsorption equipment connected in sequence. The desiccator is provided with an adsorbent for removing water, and the pressure swing adsorption device is provided with an adsorbent for removing carbon. The pretreatment equipment adopts physical method to purify N 2 O contained in the tail gas of nitric acid industry, which saves energy and reduces emissions. Compared with other existing equipment for chemical removal of carbon from tail gas and purification of N 2 O, it can avoid secondary pollution of waste lye, low cost and easy to operate. Safety advantage. The purification device includes the pretreatment equipment provided by the utility model. The purification device uses physical methods to remove impurities and high-pressure throttling refrigeration rectification technology, which is easier to operate than traditional purification devices, and the product N 2 O has high purity, which can meet the needs of domestic and foreign markets. |
