| titleOfInvention | O-nitrotoluene recovery device |
| abstract | The utility model discloses an adjacent nitrotoluene recovery unit, etherate mother liquor feeding system is connected to the feed end of etherate mother liquor storage jar, the discharge end of etherate mother liquor storage jar is connected with the feed end of scraper blade evaporimeter, the upper end gas vent of scraper blade evaporimeter is connected with the air inlet of adjacent nitrotoluene recovery jar, vacuum pumping system is connected to the exhaust end of adjacent nitrotoluene recovery jar, the lower extreme discharge end of scraper blade evaporimeter is connected with the feed end of blender with the discharge end of methyl alcohol storage jar jointly, the discharge end of blender is connected with the feed end of burning furnace, methyl alcohol feeding system is connected to the feed end of methyl alcohol storage jar, the lower extreme discharge end and the production headtotail of adjacent nitrotoluene recovery jar. The utility model discloses an ortho-nitrotoluene is retrieved in the continuous distillation, reduction in production cost, and the cauldron incomplete material of distilling passes through toluene and dilutes the cooling in succession, makes the cauldron incomplete material not take place the autopolymerization, guarantees to retrieve ortho-nitrotoluene's security. |
