Description

The invention relates to petroleum engineering for the field preparation of oil.

The purpose of the invention is to increase efficiency and productivity.

FIG. 1 shows an electrode-hydrator, a cross-section; in fig. 2 shows section A-A in FIG. 1 {fig, 3 - tube of a lattice element, a section.

The horizontal cylindrical housing 1 has collectors for inlet 2 and outlet 3 for oil, ventilating grid electrodes 4 with electrical supply equipment in the form of insulators 5 and lead-in conductors 6 and four volume lattice elements placed on both sides of the electrodes 7. Electrodes 4 and elements 7 are attached with insulators - Grades 8 to body 1. Grates 7 are made of conductive material. A perforated partition 9 extends along the bottom at a certain height and on the wall to separate the separated water, which drains through the pipe 10. The plates 11 are installed to evenly distribute the flow through the electrodes 4 and the elements 7. , connected to the network, electrodes, to arrange a series of intermediate insulated elements-plates in the form of volumetric arrays, then the charge applied to them will allow the main electrodes to be moved apart for a longer distance. Since the elements are voluminous, a gap is created between the front and rear parts of the elements connected to the lattice, where the charged liquid particles will be forced to be redistributed along the surfaces of the element so that after giving charge, the lattice will stick to on them with their bias. Those fluid particles that did not linger on

this element, experience a similar effect on the following elements

Electrodehydrator works as follows.

Into housing 1, through the collector 2 inlets, there is an oil flow, which turns around, separating and separating water with a partition 9 and flaps 11, jg. Particles of water, a passage with an oil flow through the first element 7 with induced electric charge, can acquire a charge, and occasional trickles water

can flow down through the tubes of bulk gratings 7. Next, the fluid passes successively through electrode 4 and element 7, then experiencing an electric field of alternating or direct current, then entering the neutral zone inside the volume of electrode 4 and elements 7, and the lattice structures belong to the active the role of absorption and removal of water particles into the lower zone of the housing 1. A sufficiently large number of electrodes 4 and elements 7 will allow increasing the flow rate in order to turbulent the flow on the elements 7 and electrodes 4 for better coalescence of water particles and to resist them in the lower zone without opposing the flow direction. Since the flow to the collector 3 exits the periphery and its periphery circulates as it moves, a part of the lower stream, which is not yet sufficiently purified, returns forward to the beginning

process, together with the main flow of oil from the reservoir 2 input. The principle of repeated action characteristic of the known device is somewhat unfortunate due to the deterioration of the process stability. In this case, the process is stabilized. The angle of inclination of the electrodes 4 and the elements 7, their tubular structure, allows water droplets to penetrate into the hole 13 to bring it down.

Efficiency improvement is achieved due to repeated interaction of the flow with the electrodes and bulk lattice structures with induced charge. Increasing field heterogeneity with a simultaneous decrease in the probability of direct electrical breakdown allows an increase in the capacity of the proposed electric dehydrator.
