Amide oil agent continuous water removal device and its water removal process

Abstract

The invention introduces a continuous water removal device for amides oil and a water removal process thereof. An oil regulating valve, a U-tube heat exchanger, an on-line moisture detector and an oil reception trough are arranged in sequence in the oil supply and flow path. The U-type tube heat exchanger is connected with heat transfer steam inlet and outlet pipelines, and the U-type heat exchanger pipe shell is also respectively connected with an oil inlet, a vacuum suction port, a vacuum detector, and an oil discharge pipeline. The vacuum pipeline is connected with a vacuum regulator valve and a vacuum system. In the water removal process adopted in the invention, the vacuum of the vacuum system is less than 97.3KPa, and the temperature of the oil in the pipe shell is 70 to 75 DEG C. The invention realizes continuous production, effectively controls the moisture in the oil, and the heat exchanger has the advantages of small input and small occupied area.

Description

technical field [0001] The invention belongs to the dehydration technology of chemical oil agent. Background technique [0002] At present, the dehydration of chemical oil agents usually adopts batch dehydration process. [0003] Batch-type dehydration is to reduce the pressure of the distillation pot, and intermittently heat the water-containing material to a certain temperature to evaporate the water. This dehydration method has high energy consumption and low water removal rate. [0004] The invention with the patent application number 2012100240167 relates to an ECX gathering type oil-water separator. The oil-water separator is composed of a water inlet distribution chamber, a primary separation chamber, a secondary separation chamber, and a water collection chamber. The water inlet distribution chamber is composed of a water inlet and a water distribution pipe, and the partitions are arranged between each chamber. Separated, each chamber is provided with an oil discha...

The invention is an isolated dehydration equipment and cannot be used for continuous operation

[0005] The invention with the patent application number 2013102459421 discloses an online circulation oil-water separation discharge system, including an online oil-water separation circulation system, a sewage recovery system, a drainage system, a PLC electrical control system with a man-machine interface, and a water collection well. The online oil-water separation The system includes a deep sewage collection device placed in a water collection well and an oil-water separation system. The deep sewage collection device is connected to the oil-water separation system through pipelines. A sewage pump is installed on the outlet pipeline of the deep sewage collection device. In the oil-water separation system An online oil concentration monitoring analyzer is installed at the entrance of the water tank, and an automatic flow control valve is provided on the pipelines connected to and connected to the oil-water separation system. The drainage system includes a drainage pump whose inlet is located at the bottom of the water collection well; the invention It only separates the layered oil and water, and cannot separate the miscible oil and water, and the separation effect is poor
