Problems solved by technology
[0002] In the process of producing polyester, it is necessary to add heat medium to the esterification heat exchanger. The pressure in the traditional esterification heat exchanger is difficult to control, and it is necessary to manually adjust the heat medium feed pipe to supply heat to the esterification heat exchanger. material speed
For large-scale production lines, if manual operation is required, a lot of labor will be wasted, and the pressure control accuracy in the esterification heat exchanger is difficult to grasp

The invention relates to a heating medium feed pipe control system of an esterification heat exchanger. The heating medium feed pipe control system comprises the esterification heat exchanger (1), and a feed opening of the esterification heat exchanger (1) is connected with a heating medium feed pipe (2). The heating medium feed pipe control system is characterized in that a feed valve (2.1) and a pressure transmitter (2.2) are sequentially arranged on the heating medium feed pipe (2) from front to rear, a control circuit (3) is arranged between the feed valve (2.1) and the pressure transmitter (2.2), and a pressure controller (3.1) is arranged on the control circuit (3). The heating medium feed pipe control system of the esterification heat exchanger has the advantages of being high in pressure control accuracy and saving labor.
Description
technical field [0001] The invention relates to an esterification heat exchanger, in particular to a heat medium feed pipeline control system of the esterification heat exchanger, which belongs to the field of chemical equipment. Background technique [0002] In the process of producing polyester, it is necessary to add heat medium to the esterification heat exchanger. The pressure in the traditional esterification heat exchanger is difficult to control, and it is necessary to manually adjust the heat medium feed pipe to supply heat to the esterification heat exchanger. material speed. For large-scale production lines, if workers are required to manually operate, a lot of labor will be wasted, and it is difficult to control the pressure control accuracy in the esterification heat exchanger. Therefore, it is particularly important to seek a heat medium feed pipeline control system for esterification heat exchangers with high pressure control precision and labor-saving. ...
