Abstract
The utility model relates to a heat recycling system, in particular to a heat recycling system of an esterifying and separating tower, belonging to the technical field of chemical machinery. The heat recycling system comprises an esterifying kettle (1), a first heat exchanger (2), a glycol recycling tank (3) and a third heat exchanger (6). The utility model is characterized in that the heat recycling system further comprises a second heat exchanger (4) and an air cooler (5). In the heat recycling system, high-temperature water vapor separated from the esterifying kettle is used for heating glycol required by the esterifying kettle, and an air cooling device is additionally arranged to reduce the energy consumption of the heat exchangers. Therefore, energy sources are saved, the energy consumption is reduced, the workload of the heat exchangers is reduced, and the production cost is lowered.
Description
(1) technical field
The utility model relates to a kind of heat reclaiming system, relates in particular to a kind of heat reclaiming system of esterification knockout tower, belongs to the chemical mechanical equipment technical field.
(2) background technology
Esterifying kettle can be isolated the steam of high temperature when separating ethylene glycol and water, these steam are lowered the temperature by heat exchanger and collected in the tank.In the process of high-temperature vapor cooling, the workload of heat exchanger is very big, and bigger power consumption has improved production cost.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of energy savings, cuts down the consumption of energy, and has also reduced the heat reclaiming system of the esterification knockout tower of production cost.
The purpose of this utility model is achieved in that
A kind of heat reclaiming system of esterification knockout tower, comprise esterifying kettle, first heat exchanger, the ethylene glycol recycling can, the 3rd heat exchanger and return flume, the top of described esterifying kettle is distillation cascade, the inlet of described esterifying kettle links to each other with the sidepiece outlet of first heat exchanger, the bottom liquid outlet of described esterifying kettle links to each other with the bottom inlet of first heat exchanger, described ethylene glycol recycling can links to each other with the side mouth of distillation cascade, the thermal medium outlet of described the 3rd heat exchanger links to each other with return flume, it is characterized in that: it also comprises second heat exchanger and air cooler, the thermal medium import of described second heat exchanger links to each other with the top of distillation cascade, the thermal medium outlet of described second heat exchanger links to each other with the import of air cooler, the cold media outlet of described second heat exchanger links to each other with the bottom inlet of first heat exchanger, and the outlet of described air cooler links to each other with the thermal medium import of the 3rd heat exchanger.
The beneficial effect that the utlity model has is:
In the heat reclaiming system of this esterification knockout tower isolated high-temperature vapor in the esterifying kettle is used for heating ethylene glycol required in the esterifying kettle, and increased the energy consumption that air cooling device reduces heat exchanger, not only saved the energy, reduced energy consumption, also reduce the workload of heat exchanger, reduced production cost.
(4) description of drawings
Fig. 1 is the structural representation of the heat reclaiming system of the utility model esterification knockout tower.
Wherein: esterifying kettle 1, distillation cascade 1.1, first heat exchanger 2, ethylene glycol recycling can 3, second heat exchanger 4, air cooler 5, the 3rd heat exchanger 6, return flume 7.
(5) specific embodiment
As Fig. 1, the utility model relates to a kind of heat reclaiming system of esterification knockout tower, comprises esterifying kettle 1, first heat exchanger 2, ethylene glycol recycling can 3, second heat exchanger 4, air cooler 5, the 3rd heat exchanger 6 and return flume 7;
The top of described esterifying kettle 1 is distillation cascade 1.1, the inlet of described esterifying kettle 1 links to each other with the sidepiece outlet of first heat exchanger 2, the bottom liquid outlet of described esterifying kettle 1 links to each other with the bottom inlet of first heat exchanger 2, described ethylene glycol recycling can 3 links to each other with the side mouth of distillation cascade 1.1, the thermal medium import of described second heat exchanger 4 links to each other with the top of distillation cascade 1.1, the thermal medium outlet of described second heat exchanger 4 links to each other with the import of air cooler 5, the cold media outlet of described second heat exchanger 4 links to each other with the bottom inlet of first heat exchanger 2, the outlet of described air cooler 5 links to each other with the thermal medium import of the 3rd heat exchanger 6, and the thermal medium outlet of described the 3rd heat exchanger 6 links to each other with return flume 7.
In the cold medium import of second heat exchanger 4, feed ethylene glycol, when isolated high-temperature vapor is by second heat exchanger 4 in the esterifying kettle 1 ethylene glycol is heated, ethylene glycol after the heating flows in first heat exchanger 2 again, has reduced the workload of first heat exchanger 2.The steam that passes through from second heat exchanger 4 feeds subsequently in the air cooler 5 and feeds the 3rd heat exchanger 6 again after the cooling once more, has reduced the workload of the 3rd heat exchanger 6.
