| titleOfInvention | Methyl hydrazine feeding system in process of synthesizing pyrazole acid from methyl hydrazine |
| abstract | The utility model belongs to the technical field of pyrazole acid synthesis, in particular to a methyl hydrazine feeding system in the process of synthesizing pyrazole acid by methyl hydrazine, which comprises a diaphragm pump and a metering tank; one end of the diaphragm pump is connected with the methyl hydrazine storage barrel through a pipeline, and the other end of the diaphragm pump is connected with the feeding hole of the metering tank through a pipeline; and a deionized water inlet and a nitrogen inlet are arranged on a pipeline connecting the diaphragm pump and the methyl hydrazine storage barrel. Aiming at using a main raw material methyl hydrazine in the process of synthesizing a pyrazole acid product, a common feeding mode of a diaphragm pump and a metering tank is adopted, the feeding safety can be ensured, and the feeding system can be thoroughly cleaned after the feeding is completed by arranging a distilled water inlet and a nitrogen inlet, so that the safety of the system is ensured. In a word, the device of the utility model can reduce the potential safety hazard of methylhydrazine and ensure the smooth operation of the production of pyrazole acid. |
