Abstract
The utility model relates to a heat recycling device, in particular to the heat recycling device of an esterification kettle, belonging to the technical field of chemical and mechanical equipment. The heat recycling device comprises the esterification kettle (1), a first heat exchanger (2), a glycol recovery tank (3) and a third heat exchanger (6), and is characterized in that the heat recycling device additionally comprises a second heat exchanger (4). Since the heat recycling device of the esterification kettle can use high-temperature water vapor separated out from the esterification kettle to heat glycol required by the esterification kettle and an air cooling device is added to reduce the energy consumption of the heat exchangers, the energy is saved, the energy consumption is decreased and the production cost is decreased.
Description
(1) technical field
The utility model relates to a kind of heat reclamation set, relates in particular to a kind of heat reclamation set of esterifying kettle, 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 reclamation set of the esterifying kettle of production cost.
The purpose of this utility model is achieved in that
A kind of heat reclamation set of esterifying kettle, comprise esterifying kettle, first heat exchanger, ethylene glycol recycling can and the 3rd heat exchanger, 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, it is characterized in that: it also comprises second heat exchanger, the thermal medium import of described second heat exchanger links to each other with the top of distillation cascade, the thermal medium of described second heat exchanger exports and links to each other with the thermal medium import of the 3rd heat exchanger, and the cold media outlet of described second heat exchanger links to each other with the bottom inlet of first heat exchanger.
The beneficial effect that the utlity model has is:
In the heat reclamation set of this esterifying kettle isolated high-temperature vapor in the esterifying kettle is used for heating ethylene glycol required in the esterifying kettle, has not only saved the energy, reduced energy consumption, also reduced production cost.
(4) description of drawings
Fig. 1 is the structural representation of the heat reclamation set of the utility model esterifying kettle.
Wherein: esterifying kettle 1, distillation cascade 1.1, first heat exchanger 2, ethylene glycol recycling can 3, second heat exchanger 4, the 3rd heat exchanger 5, return flume 6.
(5) specific embodiment
As Fig. 1, the utility model relates to a kind of heat reclamation set of esterifying kettle, comprises esterifying kettle 1, first heat exchanger 2, ethylene glycol recycling can 3, second heat exchanger 4, the 3rd heat exchanger 5 and return flume 6;
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 thermal medium import of the 3rd heat exchanger 5, the cold media outlet of described second heat exchanger 4 links to each other with the bottom inlet of first heat exchanger 2, and the thermal medium outlet of described the 3rd heat exchanger 5 links to each other with return flume 6.
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.
Claims (1)
