Description
Technical field
The present invention relates to crude Treatment technical field, and in particular to a kind of desalination structure pre-processed for crude oil.
Background technology
Air-distillation and vacuum distillation are traditionally collectively referred to as atmospheric and vacuum distillation, and atmospheric and vacuum distillation belongs to physical process substantially.Raw material
Oil is divided into the different oil product of boiling spread (be referred to as cut) in destilling tower by evaporability, these oil have through concocting, attaching
Plus dispatched from the factory after agent with product form, sizable part is the raw material of following process device, and therefore, atmospheric and vacuum distillation is otherwise known as
The time processing of crude oil.Including three processes：Desalination, the dehydration, air-distillation, vacuum distillation of crude oil.
The crude oil of oil plant often saliferous (mainly chloride) band water (being dissolved in oil or in emulsified state) is sent to from oil field
The corrosion of equipment can be caused, in equipment inner wall fouling and the composition of influence product oil, so need to remove before processing.
Method commonly used in the prior art is plus demulsifier and water to make the water collection in oil, and is separated from oil, and salt is molten
Yu Shuizhong, then it is subject to high voltage electric field cooperation, the large water droplet to be formed smoothly is removed.
But it is not ideal to the treatment effect of salt and water using existing desalter, single desalting and dewatering rate is low, always
It is to need multiple desalting processing, processing cost is high.
The content of the invention
It is an object of the invention to provide a kind of desalination structure pre-processed for crude oil, existing desalter list is solved
The problem of secondary desalting and dewatering rate is low.
The present invention is achieved through the following technical solutions：
A kind of desalination structure pre-processed for crude oil, including the electrical desalter of high voltage electric field mechanism is internally provided with,
One end of electrical desalter is provided with outlet of sewer, and the high voltage electric field mechanism includes several positive electrode plates and negative electrode plate, institute
Positive electrode plate and negative electrode plate is stated to be alternately arranged along the axially in parallel of electrical desalter and equidistantly constitute a plurality of water removal channel, it is described
Water removal channel is communicated with outlet of sewer, and several suction holes are also provided with positive electrode plate and negative electrode plate, and the suction hole exists
It is uniformly distributed on positive electrode plate and negative electrode plate.Further, the inner workings of electrical desalter are：Chlorine in water and crude oil
Compound is mutually mixed and ionized in the effect of high voltage electric field, forms zwitterion, then zwitterion is between positive-negative electrode plate
Electric field action motion, gradually condense into small water droplet.But existing small water droplet is too small, it is not easy to as discharge line is from outlet of sewer
In go out, it is easy to be blended in again in crude oil.So the present invention is improved to existing electrical desalter, by high voltage electric field machine
Positive and negative electrode plate in structure is equidistantly arranged in parallel, and several suction holes are then also provided with positive electrode plate and negative electrode plate,
So the small water droplet in part, ion may pass through suction hole and be attached on some battery lead plate, and several pass through the small water droplet of suction hole
Being superimposed under gravity, it is bigger insoluble in the big water droplet of oil to form, and can be easy to row compared with prior art
Waterline is gone out from outlet of sewer, and single salt rejection rate is improved with this.Such as, three adjacent battery lead plates are followed successively by positive electrode
Plate, negative electrode plate, positive electrode plate, the cation formed in two water removal channels, two water removal channels are equal in the presence of electric field
Moved toward the direction close to negative electrode plate, a part of small water droplet is just attached to close to the side of negative electrode plate, and in the work of gravity
It is superimposed to form large water droplet under；And most of small water droplet and ion enter another water removal channel simultaneously through suction hole
The opposite side of the negative electrode plate is attached to, is superimposed to form bigger water droplet with the small water droplet or large water droplet of the side, with
The quality increase of bigger water droplet, its gravity being subject to is gradually increased, when the gravity being subject to is more than its electric field force and wall adhesive force
Make a concerted effort when, water droplet can be easy to drop as discharge line is gone out from outlet of sewer；Anion court in the presence of electric field leans on
The direction motion of nearly positive electrode plate, is also to form bigger water droplet with above same principle, when its gravity being subject to is more than its electric field
Power and wall adhesive force when making a concerted effort just as discharge line is gone out from outlet of sewer.
It is preferred that, the aperture of the suction hole is 2.5~5.5mm, if the aperture of suction hole is excessive, is easily caused crude oil and mixes
Close and enter in water removal channel；If the aperture of suction hole is too small, water droplet is easily caused again and is attached to water suction hole surface and by suction hole
Aperture is blocked.
It is preferred that, the vertical interval between two neighboring positive electrode plate and negative electrode plate is 5~8mm.
Also include crude oil oil suction chamber, the crude oil oil suction chamber is located at same one end of electrical desalter, the original with outlet of sewer
Agitator is provided with oily oil suction chamber.Further, crude oil is stirred using agitator, the salt in crude oil can be made compared with prior art
Divide and be more fully dissolved in water.
Demulsifier is also associated with the crude oil oil suction chamber and delivers pipeline and pure water dispensing pipe.Further, existing skill
Demulsifier and pure water are all manually to deliver in electrical desalter body several times in art, so very inconvenient, so of the invention
Demulsifier and pure water are conveyed respectively using pipeline in tank body, is more facilitated.
The present invention compared with prior art, has the following advantages and advantages：
A kind of desalination structure pre-processed for crude oil of the present invention, existing electrical desalter is improved, by high voltage electric field
Positive and negative electrode plate in mechanism is equidistantly arranged in parallel, and several water suctions are then also provided with positive electrode plate and negative electrode plate
Hole, so small water droplet in part, ion may pass through suction hole and be attached on some battery lead plate, and several pass through the small water of suction hole
Drop be superimposed under gravity forms it is bigger insoluble in the big water droplet of oil, can be easy to compared with prior art with
Discharge line is gone out from outlet of sewer, improves single salt rejection rate, and economic and environment-friendly, the process that can reduce desalination, reduction is processed into
This, with high use value.
