Abstract

The invention relates to devices for the purification of oil from water, crystalline salts and mechanical impurities and makes it possible to increase the efficiency of the electro-dehydrator. The electrodehydrator consists of a housing 1 in which a negative electrode (E) 2 and a positive E 6, made in the form of a hollow cylinder made of porous conducting material, are coaxially mounted. Positive E 6 is installed with a gap in relation to the side wall of housing 1. Globules of water and particles of mechanical impurities, effectively charging when passing in close proximity to the tips of needles E 2, are transported to positive E 6 on the surface of which sedimentation and enlargement of water globules and their enrichment with mechanical impurity particles under the action of electrical forces. The enlarged globules of water are carried by the flow of oil into the space between the positive E 6 and the wall of the housing 1, where due to the forces of gravity the water and mechanical impurities are separated from the oil. 1 il. and S (L 00 00 QD 00 O 00

Description

The invention relates to devices for cleaning oil from water, crystalline salts and mechanical impurities and can be used in oil fields and refineries.

The purpose of the invention is to increase the efficiency of the dehydrator.

The drawing shows an electrode dehydrator, a longitudinal section.

The electrodehydrator comprises a housing, an electrode 2 installed inside a perforated dielectric tube 3 and connected through an insulator 4 to the negative pole of a DC source 5, a positive electrode 6 made of a current-conducting porous material. The electrode 2 is fixed inside the housing 1 by means of dielectric partitions 7 and 8. The housing 1 has a removable cover 9 and is equipped with nozzles for entering the processed oil 10, draining the dehydrated and refined oil And and draining water 12.

Electrodehydrator works as follows.

Oil is fed through pipe 10. At the same time, globules of water and particles of mechanical impurities pass in close proximity to the tip of the needles of electrode 2, which ensures high efficiency of charging of globules and particles. The charged globules of water and particles of mechanical impurities are transferred by the flow of oil to

the positive electrode 6, on the surface of which is their deposition under the action of electric forces. In the process of sedimentation of the globules of water and particles of mechanical impurities on the positive electrode 6, the globules are enlarged and enriched with their impurities. At the same time, enlarged globules of water are carried into the flow of oil, where, due to the forces of gravity, water and mechanical impurities are separated from oil. Purified and dehydrated oil is discharged through pipe 11, and water and sludge through pipe 12.

The advantage of an electric dehydrator is an increase in operating efficiency, 5 due to the enlargement of water globules on the positive electrical network by enriching them with mechanical impurities.
