Full Oil Recovery Circulation System

Abstract

The invention provides a full oil recycling system. The full oil recycling system comprises a distilling process, a cool circulation process and a controller, wherein the distilling process is performed through the following devices in sequences: an absorption tower, a first circulating pump, a filter, a degassing tower, a second circulating pump, a first heat exchanger, a second heat exchanger, a desorption tower a third circulating pump, a first heat exchanger, a third heat exchanger and an absorption tower; the cool circulation process is performed through the following devices in sequences: the absorption tower, the first circulating pump, and the absorption tower; the first circulating pump is provided with a bypass pipe, and the bypass pipe is communicated with the first circulating pump and the absorption tower. The system is flexibly controlled according to the real oil outlet amount, the cool circulation device is operated when the oil outlet amount is small, the oil is accumulated in the absorption tower, and after the oil is accumulated to a certain amount, the distillation is operated, so that a great amount of electric charge can be saved, the equipment fault rate can be reduced, and the workload can be alleviated.

Description

technical field [0001] The invention belongs to the field of oil recovery systems, and in particular relates to a full oil recovery circulation system. Background technique [0002] The aluminum foil rolling mill will generate a lot of heat during the rolling process. It needs to use rolling oil (kerosene) to cool and lubricate. The rolling oil encounters heat during the spraying process and forms oil mist. The exhaust fan collects the oil mist and sends it to In the absorption tower, the rolling oil in the flue gas is dissolved and absorbed by spraying the washing oil in the absorption tower, and the formed mixed oil enters the degassing tower, and the moisture contained in the oil is removed by vacuuming. After degassing, it is heated to a certain temperature by a heat exchanger and enters the desorption tower for vacuum distillation. The rolling oil is fractionated in the form of oil and gas, and condensed into pure liquid rolling oil for recycling; The heat is cooled an...

AI Technical Summary

Problems solved by technology

[0005] 1. A lot of electric energy is wasted;

[0006] 2. The washing oil will be heated for a long time to affect the absorption effect and service life;

[0007] 3. Due to too many process links, once there is a problem in any link or some unpredictable equipment failure needs to be dealt with or repaired, the rolling mill can only stop production, affecting normal operation;

[0008] 4. It is also a huge waste if the system is not fully utilized
