Abstract
The utility model relates to a cooling material receiving pipe control system of an esterification knockout tower. The system comprises an esterification knockout tower (1). A material receiving outlet of the esterification knockout tower (1) is connected with a cooling material receiving pipe (2). The system is characterized in that the cooling material receiving pipe (2) is, from front to back, provided with a flow transmitter (3) and a cooling material feeding valve (4). A control line (5) is disposed between the flow transmitter (3) and the cooling material feeding valve (4). The control line (5) is provided with a flow controller (6). The system is advantaged by being high in flow control precision and saving manpower.
Description
Technical field
The utility model relates to a kind of esterification knockout tower, relates in particular to a kind of cooling material feed back pipe control system of esterification knockout tower, belongs to the chemical plant field.
Background technology
In producing PET Process, need to use esterification knockout tower, traditional more difficult control of esterification knockout tower cooling material feed back pipeline flow, the aperture that need to regulate manually cooling material inlet valve on cooling material feed back pipeline.For the maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of flow control accuracy of the cooling material feed back pipeline of esterification knockout tower.Therefore seek a kind of flow control accuracy higher, the cooling material feed back pipe control system of saving artificial esterification knockout tower is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of flow control accuracy higher, saves the cooling material feed back pipe control system of artificial esterification knockout tower.
The purpose of this utility model is achieved in that
A kind of cooling material feed back pipe control system of esterification knockout tower, it comprises the esterification knockout tower, the feedback outlet of described esterification knockout tower is connected with cooling material feed back pipeline, it is characterized in that being provided with from front to back flow transmitter and cooling material inlet valve on described cooling material feed back pipeline, be provided with operation circuit between described flow transmitter and cooling material inlet valve, on described operation circuit, be provided with flow controller.
Compared with prior art, the beneficial effects of the utility model are:
The utility model passes through the aperture of the signal controlling cooling material inlet valve of operation circuit, thereby controls the flow of cooling material feed back pipeline, guarantees that the flow of cooling material feed back pipeline is able to accurate control.It is higher that the cooling material feed back pipe control system of this esterification knockout tower has flow control accuracy, saves artificial advantage.
