Hot well applied in final polycondensation system

Abstract

The invention relates to a hot well applied in a final polycondensation system. The hot well comprises a well body and a filtering basket. The well body is divided into two chambers, which are a barometric leg side chamber and a basket side chamber. The filtering basket is arranged in the basket side chamber. The hot well also comprises a remote control liquidometer and a central controlling system. The remote control liquidometer is arranged in the filtering basket side chamber. The central controlling system is connected to the remote control liquidometer. With the arranged remote control liquidometer, whether the basket is blocked can be monitored by the central controlling system at any time. Once the basket is blocked, cleaning can be carried out in time, such that continuous and stable operation of a vacuum spraying system is ensured, and production accidents caused by the laxity of the staff on duty can be avoided. Therefore, unnecessary economic losses of enterprises can be avoided.

Description

technical field [0001] The invention relates to the field of polyester production equipment, in particular to a hot well applied to a final polycondensation system. Background technique [0002] The hot well is an indispensable part of polyester production. Its function is to concentrate the liquid glycol, to control the liquid level conveniently, and to provide a certain static pressure head for the glycol circulation pump, which is beneficial to the glycol circulation pump. In actual production, the hot well of the final polycondensation system, because there are more low molecular substances extracted from the reactor, finally enters the hot well through the spray condenser, and a basket is set in the hot well to filter the above-mentioned oligomers, such as figure 1 As shown, in normal production operation, due to the filtering effect of the basket, workers on duty need to check and clean the basket every time a period of time passes. The stability of its production is ...
