Description
Technical field
The utility model relates to a kind of energy-saving rectifying tower.
Background technology
During Chemical Manufacture, usually need to use rectifying column, but the rectifying column energy consumption of existing use is high, and rectification effect is poor.
Utility model content
For above-mentioned weak point, the purpose of this utility model is just to provide a kind of energy-saving rectifying tower, and this energy-saving rectifying tower rectification effect is good, and energy-conservation.
The technical solution of the utility model is: a kind of energy-saving rectifying tower, comprise oval tower top and rectification layer, oval tower top is provided with steam (vapor) outlet, rectification layer is arranged on below oval tower top, rectification layer top one sidewall is provided with inlet, described energy-saving rectifying tower also comprises the layer that boils again, and this layer that boils again is arranged at the below of rectification layer; Another sidewall of described rectification layer top is provided with phegma import, is connected with condenser between phegma import and steam (vapor) outlet.
As preferably, described rectification layer exterior side wall is provided with heat-insulation layer.
As preferably, be provided with distributor in described rectification layer, distributor is connected with phegma import by a vertical tube type passage, and vertical tube type channel bottom is evenly distributed with a duct.
As preferably, described distributor comprises circular distribution plate, distributing slot, extenal fixation ring, dowel, and distributing slot is evenly distributed on circular distribution plate, and extenal fixation ring is arranged on outside circular distribution plate, and extenal fixation ring is connected and fixed by dowel and circular distribution plate.
As preferably, the described layer that boils again comprises more than 2 layers detachable tower trays and heat exchanger, and heat exchanger is installed on detachable tower tray.
Compared with prior art, the beneficial effects of the utility model are: the utility model gas-liquid contact is good and mass-and heat-transfer even, and therefore rectification effect is good, and due to the setting of the layer that boils again, energy consumption are reduced greatly.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model liquid distribution trough structural representation;
Fig. 3 is the utility model vertical tube type channel bottom floor map.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
As Figure 1-3, a kind of energy-saving rectifying tower, comprise oval tower top 1, rectification layer 7 and the layer 6 that boils again, oval tower top 1 is provided with steam (vapor) outlet 12, and rectification layer 7 is arranged on below oval tower top 1.
Rectification layer 7 top one sidewall is provided with inlet 2, and another sidewall is provided with phegma import 9, is connected with condenser 10 between phegma import 9 and steam (vapor) outlet 12, condenser 10 is also connected with top discharge pipe rectification layer 7 exterior side wall and is provided with heat-insulation layer 3.
Be provided with distributor 8 in rectification layer 7, distributor 8 is connected with phegma import 9 by a vertical tube type passage 11, and vertical tube type passage 11 bottom even is distributed with a duct 111.
Distributor 8 comprises circular distribution plate 82, distributing slot 83, extenal fixation ring 81, dowel 84, distributing slot 83 is evenly distributed on circular distribution plate 82, extenal fixation ring 81 is arranged on outside circular distribution plate 82, and extenal fixation ring 81 is connected and fixed by dowel 84 and circular distribution plate 82.Adopt this structure not easily to occur causing to the flowing of tower wall the tendency of " wall stream ", ensure that liquid distribution is even, improve mass-transfer efficiency.
The layer 6 that boils again is arranged at the below of rectification layer 7, then the layer 6 that boils comprises more than 2 layers detachable tower trays 4 and heat exchanger 5, and heat exchanger 5 is installed on detachable tower tray 4.
In the utility model, phegma first enters vertical tube type passage 11 from phegma import 9, phegma forms certain liquid level in vertical tube type passage 11, liquid-level pressure can guarantee that each duct 111 has liquid to pass through, therefore gas-liquid contact is good and mass-and heat-transfer even, thus rectification effect obviously promotes.
Above-mentioned embodiment is only unrestricted as explanation of the present utility model; the utility model protection domain also should comprise those apparent conversions to those skilled in the art, conversion, change or substitute; and in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
