Abstract
The utility model discloses a rectifying tower which comprises a rectifying tower body, and a primary distillation layer and a rectification layer, wherein the primary distillation layer is arranged above the rectification layer. The rectifying tower is internally provided with an evaporating and re-boiling layer that evaporates liquid to gaseous phase. The evaporating and re-boiling layer is arranged below the rectification layer. The rectifying tower has the advantages that the rectifying tower is internally provided with the evaporating and re-boiling layer which evaporates liquid to gaseous phase so as to combine the rectifying tower with the re-boiler, so that the occupied area of the device is reduced, the manufacturing cost of the device is lowered, and meanwhile, the heat exchange efficiency is greatly improved.
Description
Technical field
The utility model belongs to the relevant device of chemical industry and pharmaceutical industry, particularly a kind of rectifying column.
Background technology
Rectifying column is a kind of tower vapor-liquid contacting apparatus that carries out rectifying, and steam gets at the bottom of by tower, evaporates the gas phase and the decline liquid that and carries out counter current contacting; Two contact, and volatile (low boiling) component in the decline liquid constantly shifts in gas phase, and difficulty volatilization (higher boiling) component in the gas phase constantly shifts in decline liquid; Gas phase is more near cat head, and its volatile components concentration is higher, and decline liquid is more near at the bottom of the tower; Its difficult volatile component is more enrichment then, thereby reaches the purpose that component is separated.The liquid that tower bottom flow goes out, a part is wherein sent into reboiler, and heating evaporation becomes gas phase to return in the tower, and another part liquid takes out as the still raffinate
Present most of destilling tower need be joined a reboiler, liquid heat is flashed to gas phase return in the tower, has increased the floor space of equipment, has also improved the manufacturing cost of equipment.
The utility model content
The utility model technical problem to be solved is that a kind of rectifying column that liquid is flashed to gas-phase apparatus that directly is provided with in inside is provided.
For solving the problems of the technologies described above; The rectifying column that the utility model provides; It comprises the rectifying column body that is provided with first steaming layer and rectifying layer; Saidly just steam the top that layer is located at the rectifying layer, be provided with the evaporation that liquid the is flashed to gas phase layer that boils again in the said rectifying column, the said evaporation layer that boils again is located at the below of rectifying layer.
As preferably, the said evaporation layer that boils again comprises and on said each tower tray disc heat interchanger is installed all by the multilayer tower tray that said tower tray is fixedly connected with rectifying column.
After adopting above structure, the rectifying column of the utility model compared with prior art has the following advantages: be provided with the evaporation that liquid the is flashed to gas phase layer that boils again in the inside of rectifying column; Rectifying column and reboiler are united two into one, reduce the floor space of equipment, reduce the manufacturing cost of equipment; Simultaneously, the still raffinate from top to bottom passes through the disc type heat exchanger, carries out heat exchange with heat medium in the disc type heat exchanger; To reach the purpose that flashes to gas phase once more, improve heat exchanger effectiveness greatly.
Description of drawings
Fig. 1 is the configuration diagram of the utility model rectifying column;
Fig. 2 is the partial enlarged drawing of the utility model rectifying column.
Wherein: just steam layer 1, rectifying layer 2, evaporate boil again layer 3, tower tray 3.1, disc heat interchanger 3.2.
The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Like Fig. 1～shown in Figure 2; It comprises the rectifying column body that is provided with first steaming layer 1 and rectifying layer 2; Saidly just steam the top that layer 1 is located at rectifying layer 2, be provided with the evaporation that liquid the is flashed to gas phase layer 3 that boils again in the said rectifying column, the said evaporation layer 3 that boils again is located at the below of rectifying layer 2.
Preferred as present embodiment, the said evaporation layer 3 that boils again comprises multilayer tower tray 3.1, on said each tower tray 3.1 disc heat interchanger 3.2 is installed all, and said tower tray 3.1 is fixedly connected with rectifying column.
The still raffinate is from top to bottom through being installed in the disc type heat exchanger 3.2 on the tower tray 3.1, and the still raffinate carries out heat exchange with disc type heat exchanger 3.2 interior heat mediums simultaneously, with reach fully, heat exchange purpose fast, improved heat exchanger effectiveness greatly.
Claims (2)
