Vacuum fiber membrane type oil dewatering treatment device

Abstract

The invention discloses a vacuum fiber membrane type oil dewatering treatment device which comprises an oil tank, wherein the oil outlet of the oil tank is connected with the inlet of a low-pressure oil pump through a pipeline; the outlet of the low-pressure oil pump is connected with the inlet of a granule filter through a pipeline; the outlet of the granule filter is connected with the oil inletend of a fiber membrane oil-water separator through a pipeline; the oil return end of the fiber membrane oil-water separator is connected with the oil inlet of the oil tank through a pipeline; the exhaust hole of the fiber membrane oil-water separator is connected with a vacuum pump through a pipeline; and a hydrophilic hollow fiber membrane is mounted inside the fiber membrane oil-water separator. The vacuum fiber membrane type oil dewatering treatment device disclosed by the invention is capable of simply, conveniently and effectively removing moisture in oil without changing the state of the oil, the whole device operates at low pressure, electricity consumption and oil seepage risks can be reduced, the air is not in direct contact with the oil, and thus the oil has no oxidation risk.

Description

technical field [0001] The invention relates to the technical field of filtration and purification, in particular to a vacuum fiber membrane oil dehydration treatment device. Background technique [0002] Moisture in the oil, especially in the oil during work, will cause great harm: such as rust and pitting on the surface of metal parts; precipitation of hydrophilic additives; accelerated oil deterioration, thereby shortening the use of oil Life, more serious is to shorten the service life of the equipment or cause accidents, so it is necessary to dehydrate and filter the oil containing micro-moisture. The existing oil dehydration and filtration treatment methods include vacuum method, centrifugal separation method, etc. The process is to heat and atomize the oil liquid, and then use a vacuum pump to remove water. The disadvantages are: high heating power, complicated process, The equipment is bulky, heavy, and complex in structure, and there is a risk of oxidation in direc...

[0002] Moisture in the oil, especially in the oil during work, will cause great harm: such as rust and pitting on the surface of metal parts; precipitation of hydrophilic additives; accelerated oil deterioration, thereby shortening the use of oil life, and more seriously, shorten the service life of the equipment or cause accidents, so the oil containing micro-moisture must be dehydrated and filtered

The existing oil dehydration and filtration treatment methods include vacuum method, centrifugal separation method, etc. The process is to heat and atomize the oil liquid, and then use a vacuum pump to remove water. The disadvantages are: high heating power, complicated process, The equipment is large in size, heavy in weight, complex in structure, and there is a risk of oxidation in direct contact between oil and air
