Abstract
The invention relates to the technology of electrostatic coalescers, in particular to a cylinder electrode electrostatic coalescer. The cylinder electrode electrostatic coalescer is provided with a cylindrical shell and an electrode located in the shell. The electrode comprises a barrel-shaped inner electrode and a barrel-shaped outer electrode which are formed by reeling elastic metal. The inner electrode is provided with an inner electrode insulation layer. The outer electrode is provided with an outer electrode insulation layer. One end of the shell is provided with a high-voltage insulation wire inlet, and the other end of the shell is provided with an oil-water emulsion inlet. The portion, close to the high-voltage insulation wire inlet, on the side of the shell is provided with an oil-water emulsion outlet. The inner electrode is connected with the high-voltage end of an external transformer through the high-voltage insulation wire inlet. The shell is connected with a ground wire. The flowing speed of the oil-water emulsion in the cylinder electrode electrostatic coalescer is decreased, residence time in the electric field is long, the oil-water emulsion is greatly subjected to the effect of electric field force, water drops in oil achieve sufficient collision and coalescence and are combined into large granules to be sedimented out, and oil-water separation efficiency is improved.
Description
Technical field
The present invention relates to electrostatic coalescer technology, especially a kind of cylinder electrode electrostatic coalescer.
Background technology
Electrostatic coalescence device is the ingredient that the oil-water separation system in each oil field is indispensable, and China is the biggest
What part oil vapor treatment station, multi-purpose station were currently used is all traditional electric dehydrator, but tradition electric dehydrator is deposited
In problems with: (1) requires high input voltage；(2) cost and the floor space of equipment are big；(3) energy consumption
Greatly, security and stability is poor.In sum, traditional electro-dewatering apparatus (electrostatic coalescer) has been difficult to reality
Existing production requirement, along with the difficulty of crude oil dehydration continues to increase, it is updated and transform imperative.
Existing electrostatic coalescer population structure mainly has two kinds: one is self reliance type, i.e. coalescence part is by wrapping
Covering or the electrode composition of uncoated insulating barrier, separator is then in outside coalescer；Another kind is that integration sets
Meter, i.e. bare electrode is placed in coalescer top, occurs wherein the while of coalescing and settle.The edge effect of electrode
And for producing the ultimate range between the power supply determining electrode added by sufficiently high electric field intensity.For the former,
Electrode spacing increase then fringe field becomes apparent from, and for the latter, the design of transformator and circuit are shadows
Ring the principal element of coalescence effect.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, and the present invention provides a kind of cylinder electrode quiet
Electricity coalescer.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of cylinder electrode electrostatic coalescence
Device, this coalescer has the shell of cylinder and is positioned at the electrode of shell, and described electrode includes by elastic gold
Belonging to the inner and outer electrodes rolling into tubular, described interior electrode is provided with interior electrode dielectric layer, on external electrode
Being provided with external electrode insulating barrier, one end of described shell is provided with High-Voltage Insulation wire entry, and its other end is profit
The entrance of emulsion, is provided with the outlet of water-oil emulsion at shell sidepiece, close High-Voltage Insulation wire entry,
Described interior electrode is connected with external transformer high-pressure side through High-Voltage Insulation wire entry, earthing of casing line.
Further, there is between described interior electrode and external electrode the runner of water-oil emulsion.
Further, described interior electrode dielectric layer is the pvc pipe of diameter 50mm, and the thickness of this pvc pipe is 2mm.
Further, the High-Voltage Insulation wire entry end of this coalescer is provided with steam vent.
The invention has the beneficial effects as follows: water-oil emulsion flows through slowing of the present invention, stops in the electric field
Time is elongated, relatively big by electric field force effect, and the abundant collision coalescence of water droplet in oil is merged into larger particles and sinks
Fall out, improves oil-water separation efficiency.
