Method for conglomerating particulate matters in oil

Abstract

The invention relates to a method for conglomerating micro particulate matters in oil, which is characterized by comprising that: firstly, the oil is introduced into an oil inlet pipe and divided into two branches by a branching device, and the oil in each branch flows into two insulating tube cavities respectively; the particulate matters in the oil of the two branches are taken with charges of different polarities respectively under the action of strong voltage outside; the charged particulate matters in the oil enter a mixer and are fully mixed, the particulate matters in the fluid are continuously mutually 'conglomerated to become large' and collected by a filter plant; and ultramicro particulate matters which are not neutralized yet enter an oil piping system with high electrification and are neutralized and conglomerated with the particulate matters with original charges deposited in the whole oil piping system, so that the particulate matters in the oil piping system are gradually neutralized and fall off. The method can purify the particulate matters in the oil to the submicron degree, thereby recovering the surface tension of the oil, improving the quality of the oil, achieving the purification aim truly, and having good protection function on precision equipment with high requirement on the oil.

Description

technical field [0001] The invention relates to a method for agglomerating particles in oil products, in particular to a method for agglomerating particles in oil products in various fields such as engine oil, diesel oil, edible oil and industrial oil. Background technique [0002] At present, the treatment methods for particulate impurities in oil products are mainly realized by mechanical filtration methods and centrifugal filtration methods. [0003] Ordinary mechanical oil filtering methods filter mechanical impurities mainly through two parts: the primary filter and the fine filter. The primary filter is a cylindrical metal mesh to prevent larger solid particles in impure oil. The fine filter device is a small hand-pressed plate-and-frame filter element, which uses special filter paper to filter tiny particles. The impure oil enters the fine filter device and passes through the filter paper to become filtered oil. The solid impurities in the oil are trapped on the su...

AI Technical Summary

Problems solved by technology

If the precision of the filter is increased, the filter will be easily blocked

In addition, when the precision filter is fully loaded, back pressure will be generated, causing the filter to perforate, and the filter will not work at this time;

[0007] (2) The centrifugal filtration method is very difficult to filter out particles of 10-30 microns, and cannot filter out small particles less than 10 microns and ultrafine particles less than 3 microns

[0008] To sum up, the traditional treatment methods for particulate matter in oil can only effectively remove large and medium-sized particles in oil, but cannot completely purify oil
