| titleOfInvention | Full-automatic negative pressure type vacuum rapid and efficient acid dispelling system |
| abstract | The utility model discloses a full-automatic negative pressure type vacuum rapid and efficient acid dispelling system, relating to the technical field of experimental appliances; a digestion tank is arranged in a heating groove of the graphite furnace, a digestion tank plug is arranged at the upper end of the digestion tank, an exhaust pipe is connected to the upper end of the digestion tank plug, one end of the exhaust pipe is communicated with the interior of the digestion tank, the other end of the exhaust pipe is connected with the interior of a first-stage absorption tower, the first-stage absorption tower is connected with a first acid gas displacer in a second-stage absorption tower through a first connecting pipe, the second-stage absorption tower is connected with a second acid gas displacer in a third-stage absorption tower through a second connecting pipe, the third-stage absorption tower is connected with the interior of a fourth-stage absorption tower through a third connecting pipe, and the fourth-stage absorption tower is connected with an air extraction joint of a; the utility model utilizes the negative pressure to reduce the boiling point of the liquid, realizes quick acid dispelling, has high consistency and is convenient to operate; the excessive loss of the sample in the traditional acid removing method is effectively avoided, and the recovery efficiency is improved; and no need of operator to take care of the operation process. |
