Abstract
The invention relates to a temperature control system of an esterification and separation column. The system comprises an esterification and separation column (1) and an esterification heat-exchanger (2). The lower part of the esterification and separation column (1) is provided with a first temperature sensor (1.1). A heat medium inlet pipeline (3) of a feed inlet of the esterification heat-exchanger (2) is provided with a first inlet valve (3.1). A first control circuit (4) is arranged between the first temperature sensor (1.1) and the first inlet valve (3.1). A cooling material inlet pipeline (5) of a feed inlet of the esterification and separation column (1) is provided with a second inlet valve (5.1). The upper part of the esterification and separation column (1) is provided with a second temperature sensor (1.2). A second control circuit (6) is arranged between the second temperature sensor (1.2) and the second inlet valve (5.1). The temperature control system of the esterification and separation column has advantages as follows: temperature control accuracy is high; and manpower is saved.
Description
Technical field
The present invention relates to a kind of Esterification separation tower, particularly relate to a kind of temperature control system of Esterification separation tower, belong to field of chemical equipment.
Background technology
In production PET Process, need to use Esterification separation tower, the more difficult control of upper temp in traditional Esterification separation tower, need the speed regulating cooling material feed pipe to charging in Esterification separation tower manually, temperature of lower in traditional Esterification separation tower is more difficult control also, needs the speed regulating heating agent feed pipe to charging in esterification heat exchanger manually.For maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of the temperature control precision of Esterification separation tower.Therefore seek a kind of temperature control precision higher, the temperature control system of saving artificial Esterification separation tower is particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of temperature control precision higher, save the temperature control system of artificial Esterification separation tower.
The object of the present invention is achieved like this:
A kind of temperature control system of Esterification separation tower, it is characterized in that it comprises Esterification separation tower and esterification heat exchanger, feed pipe and feed back pipeline is connected with between described Esterification separation tower and esterification heat exchanger, the bottom of described Esterification separation tower is provided with the first temperature sensor, the charging aperture of described esterification heat exchanger is connected with heating agent feed pipe, described heating agent feed pipe is provided with the first inlet valve, the first control circuit is provided with between described first temperature sensor and the first inlet valve, described first control circuit is disposed with the first temperature controller and pressure controller from front to back, the charging aperture of described Esterification separation tower is connected with cooling material feed pipe, described cooling material feed pipe is provided with the second inlet valve, the top of described Esterification separation tower is provided with the second temperature sensor, the second control circuit is provided with between described second temperature sensor and the second inlet valve, described second control circuit is disposed with the second temperature controller and flow controller from front to back.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention controls the aperture of inlet valve and inlet valve by the signal of control circuit, thus control heating agent feed pipe to the speed of charging in esterification heat exchanger and cooling material feed pipe to the speed of charging in Esterification separation tower, ensure that Esterification separation tower temperature is able to accurate control.It is higher that the temperature control system of this Esterification separation tower has temperature control precision, saves artificial advantage.
