Abstract
The utility model relates to a rectifying tower which comprises a tower body, wherein the middle portion of the tower body is provided with a raw material inlet, the top portion of the tower body is provided with a liquid phase backflow inlet, the lower portion of the tower body is provided with a gas phase backflow inlet, a liquid phase outlet is arranged at the bottom of the tower body, seven layers of bubbling column plates are arranged in the tower body along longitudinal direction, the raw material inlet is positioned between a second-layer column plate and a third-layer column plate from bottom to top, two sides of each layer of the column plate are provided with an inlet end and an outlet end, the inlet end is provided with an inlet weir, and the outlet end is provided with an outlet weir, moreover, in adjacent two layers of the column plates, the outlet and of the upper column plate is connected with the inlet end of the lower column plate through a downtake. Compared with the existing rectifying towers, the rectifying tower of the utility model has high heat transfer efficiency and excellent separation effect.
Description
(1) technical field
The utility model relates to a kind of rectifying column.
(2) background technology
Rectifying column is a kind of tower vapor-liquid contacting apparatus that carries out rectifying, is called destilling tower again.Two kinds of main types of plate column and packed tower are arranged.Can be divided into continuous rectifying tower and batch fractionating tower again according to mode of operation.
When rectifying column uses, steam enters at the bottom of by tower, carry out counter current contacting with decline liquid, two contact, and volatile (low boiling) component in the decline liquid constantly shifts in steam, difficulty volatilization (higher boiling) component in the steam constantly shifts in decline liquid, steam 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, reaches the purpose that component is separated.The steam that is risen by cat head enters condenser, and the part of the liquid of condensation is returned cat head as phegma and entered in the rectifying column, and remaining part is then taken out as distillate.The liquid that tower bottom flow goes out, a part is wherein sent into reboiler, and after the thermal evaporation, steam returns in the tower, and another part liquid takes out as the still raffinate.
Existing rectifying column heat exchanger effectiveness is low, inferior separating effect.
(3) utility model content
Technical problem to be solved in the utility model provides the high rectifying column of a kind of mass transfer separative efficiency.
A kind of rectifying column, comprise tower body, the tower body middle part is provided with the feed(raw material)inlet, the tower body top is provided with the liquid-phase reflux inlet, the tower body bottom is provided with the gas phase reflux inlet, tower body bottom is provided with the liquid phase outlet, and described tower body inside longitudinally is provided with seven layers of bubble type column plate, and the feed(raw material)inlet is between second layer column plate from bottom to top and the 3rd layer of column plate; Every layer of column plate both sides have the entrance point and the port of export, and entrance point is provided with inlet weir, and the port of export is provided with exit weir, and the adjacent two layers column plate port of export of column plate at the middle and upper levels adopts downspout to be connected with the entrance point of lower floor column plate.
The existing rectifying column heat transfer efficiency height of rectifying column of the present utility model, good separating effect.
(4) description of drawings
Fig. 1 is the structural representation of the utility model rectifying column.
Fig. 2 is the A-A view of rectifying column shown in Figure 1.
(5) specific embodiment
Below by the drawings and specific embodiments the technical solution of the utility model is done detailed description further.
With reference to Fig. 1, Fig. 2, a kind of rectifying column, comprise tower body 1, tower body 1 middle part is provided with feed(raw material)inlet 2, tower body 1 top is provided with liquid-phase reflux inlet 3, and tower body 1 bottom is provided with gas phase reflux inlet 4, and tower body 1 bottom is provided with liquid phase outlet 5, described tower body 1 inside longitudinally is provided with seven layers of bubble type column plate 6, and feed(raw material)inlet 2 is between second layer column plate from bottom to top and the 3rd layer of column plate; Every layer of column plate both sides have the entrance point and the port of export, and entrance point is provided with inlet weir 7, and the port of export is provided with exit weir 8, and the adjacent two layers column plate port of export of column plate at the middle and upper levels adopts downspout 9 to be connected with the entrance point of lower floor column plate.
Should be noted that at last the above only is an embodiment of the present utility model, rather than be used for limiting practical range of the present utility model, every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, be the utility model claim scope and cover.
