Problems solved by technology

[0002] The traditional vacuum distillation column with external circulation generally includes heaters, distillation pots, distillation towers, liquid collectors, condensers, coil coolers and collection tanks that are connected in sequence. The distillation towers and condensers are connected by conduits and other devices. , the firmness of its structure is poor, and the gas velocity of the collection and distribution inside the liquid is small, which is easy to cause stagnation. In addition, the condenser is only a condensation structure, and the condensation effect is poor

Embodiment Construction

[0009] Such as figure 1 As shown, the external circulation vacuum rectification column provided by the present invention includes a heater 1, a distillation pot 2, a distillation tower 3, a liquid collector 7, a condenser, a coil cooler 10 and a collection tank 12 that are sequentially conducted, and the distillation The tower 3 is directly connected to the condenser, where the heater is a tube-and-tube cycle heating, with fast heating speed and high efficiency. The condenser includes a first condenser 8 and a second condenser 9 .

[0010] Such as figure 1 , figure 2 , image 3 As shown, in the above-mentioned embodiment, the liquid collector 7 includes a housing 4, and the housing 4 is provided with a collecting plate 5 and a circular feed liquid pan 6. The collecting plate 5 is L-shaped and distributed obliquely, and the collecting plate 5 is evenly distributed. Spaced and distributed in parallel, the upper part of the collection plate 5 is also L-shaped, the bottom of t...

Abstract

The invention discloses an outer circulation vacuum rectification tower which comprises a heater, a distillation still, a distillation column, a liquid collector, a condenser, a serpentine cooler and a gathering tank, every two adjacent parts of which are mutually communicating, wherein, the distillation column and the condenser are directly connected and communicated with each other, and the condenser comprises a first condenser and a second condenser. According to the invention, since the condenser in the outer circulation vacuum rectification tower comprises the first condenser and the second condenser, such dual condensation mechanisms make condensation to be more thoroughly; and since the distillation column and the condenser are directly connected and communicated with each other and no intermediate connecting piece is used for connection, a cross-sectional area at the junction part of the distillation column and the condenser is large enough, which enables air velocity in liquid during collection and distribution to be great and retention of materials to not occur.

Description

technical field [0001] The invention relates to an external circulation vacuum rectification tower, in particular to an external circulation vacuum distillation tower in pharmaceutical equipment. Background technique [0002] The traditional vacuum distillation column with external circulation generally includes heaters, distillation pots, distillation towers, liquid collectors, condensers, coil coolers and collection tanks that are connected in sequence. The distillation towers and condensers are connected by conduits and other devices. , its structural firmness is poor, and the gas velocity of the collection and distribution inside the liquid is small, which is prone to stagnation. In addition, the condenser is only a single condensation structure, and the condensation effect is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an external circulation vacuum rectification tower, the external circulation vac...
