Problems solved by technology

[0002] The PTA esterification reactor is used for the esterification reaction. However, in the past, the liquid level of the reactor needs to be manually observed by the liquid level gauge, and then manually directly controlled the flow rate of the slurry pump to adjust the liquid level. However, the liquid level is adjusted by the power of the slurry pump. The speed of the method is slow, and the PTA material will fluctuate at this time, which will have an adverse effect on the esterification reaction

Embodiment Construction

[0010] See figure 1 , The present invention relates to an esterification reactor with flow control, including a slurry tank 1. The discharge port of the slurry tank 1 is connected to the esterification reactor 4 through a slurry pump 2, and the esterification reactor 4 A flow meter 3 is installed at the feed port of the piping to detect the liquid flow rate in the pipeline. A level gauge 5 is fixed on the outer wall of the esterification reactor 4, and the end of the level gauge 5 extends into the esterification reactor 4 for detection. This type of esterification reactor with flow control is also provided with a control box 6 which is connected to the level gauge 5 and the flow meter 3 respectively. The flow meter 3 is connected to the liquid level meter 5 and the flow meter 3 through a bypass control loop 7 The slurry pump 2 is connected, one end of the control loop 7 is located before the slurry pump 2 and the other end is located after the flow meter 3.

Abstract

The invention relates to an esterification reaction kettle with flow control, which is characterized in that it includes a slurry tank (1) and a control box (6), and the outlet of the slurry tank (1) passes through a slurry pump (2) It is connected with the esterification reaction kettle (4), the feed port of the esterification reaction kettle (4) is provided with a flow meter (3), and the outer wall of the esterification reaction kettle (4) is fixed with a liquid level gauge (5). The end of the level gauge (5) extends into the esterification reactor (4), and the control box (6) is connected with the liquid level gauge (5) and the flow meter (3) respectively, and the flow meter (3) is connected through a bypass The control loop (7) of the control loop (7) is connected with the slurry pump (2), and one end of the control loop (7) is located before the slurry pump (2), and the other end is located after the flow meter (3). This esterification reaction kettle with flow control can realize real-time control of the flow of PTA slurry, avoid material fluctuations, and ensure the normal progress of the esterification reaction.

Description

Technical field [0001] The invention relates to an esterification reaction kettle, which is used for esterification reaction of PTA materials. Background technique [0002] The PTA esterification reactor is used for the esterification reaction. However, in the past, the liquid level of the reactor requires manual observation of the level gauge, and then the flow rate of the slurry pump is directly controlled manually to adjust, but the power of the slurry pump is used to adjust the liquid level The speed of the method is slow, and the PTA material will fluctuate at this time, which will adversely affect the esterification reaction. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings and provide an esterification reactor with flow control that can control the liquid level of the reactor in real time and avoid material fluctuations. [0004] The purpose of the present invention is achieved as follows: [0005] The esterification...
