Abstract
The utility model discloses an N-vinylpyrrolidone distillation device, which comprises a charging pump, a distillation tower, a condenser connected with a gaseous phase outlet of the distillation tower, and a liquid collecting tank connected with the condenser, wherein a heat exchanger is arranged between the distillation tower and the condenser; the heat exchanger is connected with the charging pump and a material inlet of the distillation tower; the gaseous phase outlet of the distillation tower and the condenser are connected with a tube pass of the heat exchanger; and the charging pump and the material inlet of the distillation tower are connected with a shell pass of the heat exchanger. The distillation device has a simple structure, materials in the heat exchanger and distillation vapor are subjected to heat exchange, so that temperature of the materials is improved, and the materials are distilled in the distillation tower; therefore, the heating load of the distillation tower is reduced, and the temperature of the distillation vapor is reduced; and the distillation vapor is condensed in the condenser, so the load of the condenser is reduced, the distillation efficiency is improved, and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of distilling apparatus, particularly relates to a kind of N-vinyl pyrrolidone distilling apparatus.
Background technology
Distilling apparatus is the main device of distillation purifying N-ethane base pyrrolidones, and the quality of its design is directly connected to refining effect and energy resource consumption.At present, distilling apparatus design commonly used is unreasonable, and the temperature of charge that gets into destilling tower is lower, and the destilling tower heating load is high, influences distillation efficiency, and a large amount of heats can not effectively utilize during the condensation of distillation vapour, have caused energy waste.
The utility model content
The purpose of the utility model is that a kind of N-vinyl pyrrolidone distilling apparatus will be provided.
In order to achieve the above object; The technical scheme of the utility model is: a kind of N-vinyl pyrrolidone distilling apparatus; Comprise feed pump, destilling tower, the condenser that links to each other with the destilling tower gaseous phase outlet, the liquid collecting jar that links to each other with condenser; Between said destilling tower and the condenser heat exchanger is set, said heat exchanger links to each other with the material inlet of feed pump and destilling tower.
Further, described destilling tower gaseous phase outlet links to each other with the heat exchanger tube side with condenser, and described feed pump links to each other with heat exchanger shell pass with the destilling tower material inlet.
The utility model is simple in structure, carries out heat exchange through material in the heat exchanger and distillation vapour, and material temperature is improved; Get into destilling tower then and distill, so just reduced the heating load of destilling tower, the distillation stripping temperature is reduced; Get into condenser then and carry out condensation; So just reduce the load of condenser, improved distillation efficiency, reduced energy consumption.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; A kind of N-vinyl pyrrolidone distilling apparatus; Comprise feed pump 5, destilling tower 1, the condenser 3 that links to each other with destilling tower 1 gaseous phase outlet, the liquid collecting jar 4 that links to each other with condenser 3; Between said destilling tower 1 and the condenser 3 heat exchanger 2 is set, said heat exchanger 2 links to each other with the material inlet of feed pump 5 with destilling tower 1; Described destilling tower 1 gaseous phase outlet links to each other with heat exchanger 2 tube sides with condenser 3, and described feed pump 5 links to each other with heat exchanger 2 shell sides with destilling tower 1 material inlet.
Material through heat exchanger 2 carries out heat exchange with distillation vapour, and material temperature is improved, and gets into destilling tower 1 then and distills; So just reduced the heating load of destilling tower 1; The distillation stripping temperature is reduced, and gets into condenser 3 then and carries out condensation, has so just reduced the load of condenser 3; Improve distillation efficiency, reduced energy consumption.
All simple distortion of under the situation that does not break away from the utility model core, making or modification all fall into the protection domain of the utility model.
