Preferably, the height of destilling tower is 12 meters to 13 meters, obtains higher p-chlorobenzylchloride productivity ratio with the resource with less.
Further, feeding port is arranged on apart from the rice of destilling tower top, thereby guarantees that the decline liquid that feeding port enters has sufficient contact with the heating steam of bottom rising.
Separately, each destilling tower is provided with reinforcement near tip position, and reinforcement is strengthened the constant intensity of destilling tower, to firmly fix destilling tower, and strengthens its service life.
And the tower body of each destilling tower is disposed with steel wire floor, heat-insulation layer, cement layer from the inside to the outside, steel wire floor and cement layer increase the intensity of destilling tower, and heat-insulation layer has reduced the thermal loss in destilling tower.
Compared with prior art, the beneficial effects of the utility model are: destilling tower of the present utility model, by increasing to 9 to 20 meters of height, the heating steam that the decline liquid entering for destilling tower feeding port and bottom enter destilling tower provides sufficient time of contact and space, and before steam inlet, be connected with steam under pressure valve, to increase the unlifting pressure of heating steam, make heating steam have enough unlifting pressures, improve the efficiency of destilling tower separation p-chlorobenzylchloride, make the separative efficiency of p-chlorobenzylchloride be increased to approximately 90%, save the energy, and improve the market competitiveness of p-chlorobenzylchloride.
The utility model makes heating steam have enough unlifting pressures, has improved the efficiency of destilling tower separation p-chlorobenzylchloride, makes the separative efficiency of p-chlorobenzylchloride be increased to approximately 90%, has saved the energy, and has improved the market competitiveness of p-chlorobenzylchloride.
