Problems solved by technology

[0003] However, in actual production, due to the influence of many factors such as the change of the feed flow rate of the rectification tower and the change of the reflux ratio, in many cases, the output of the product from the side line of the rectification tower is not very stable, and sometimes the amount is very small. , and if the side line extraction pump is still running at this time, it is easy to cause the pumping out phenomenon, resulting in damage to the pump and affecting the service life of the pump

Abstract

The invention discloses a safe material discharging device for a rectifying tower. The safe material discharging device comprises a material charging hole and a material buffer storage tank, wherein the material buffer storage tank is connected with a material discharging hole of the rectifying tower; a material discharging hole of the material buffer storage tank is connected with a material extraction pump; a liquid level observation device is arranged on the material buffer storage tank. The material buffer storage tank has a function of buffering materials discharged from the side line of the rectifying tower, the working state of the material extraction pump is controlled according to the liquid level observation device, the sufficiency of suction flow of the material extraction pump is ensured, a phenomenon of ineffective extraction of the material extraction pump is effectively avoided, and the service life of the material extraction pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of rectification towers, in particular to a discharge device for rectification towers. Background technique [0002] In chemical production, rectification towers are often used for distillation and recovery of solvents. Taking the production of acetic acid as an example, the finished acetic acid finally obtained by the acetic acid rectification tower is drawn out by the extraction pump from the side line in the middle of the tower, and then passed through the condenser. obtained by condensation. [0003] However, in actual production, due to the influence of many factors such as the change of the feed flow rate of the rectification tower and the change of the reflux ratio, in many cases, the output of the product from the side line of the rectification tower is not very stable, and sometimes the amount is very small. , At this time, if the side line extraction pump is still running, it is easy to cause the ...
