Description
[technical field]
The electrical desalter back-purge system with automatic control that the utility model relates to a kind of, belongs to chemical machinery field.
In oil recovery or oil refining apparatus, the solid impurity that pretreatment stage electrical desalter generates in the treatment process to crude oil is deposited on
Tank bottom needs periodically to carry out sewage backwash to bottom sediment to ensure electro-desalting effect.The utility model is used for the period
Property rinse electrical desalter bottom settlings solid impurity, electrical desalter is discharged in sludge.
[background technique]
The crude oil gone out from oil mining contains the impurity such as many water and silt, generally passes through in the preprocessing process of crude oil
Three major process units such as primary separator, second-stage separator and electro-desalting processor.It is big after through preceding two-stage separator
Part silt can remove, but since separator operating temperature is relatively low, oil-water emulsion fluid viscosity is larger, and tiny silt is still
Electrical desalter can be entered with oil-water emulsion.Before entering electrical desalter, the crude oil emulsion containing tiny silt can be heated,
Temperature increases the viscosity that can reduce emulsion, during subsequent high voltage electric field carries out electric dehydration electro-desalting, crude oil emulsion
In tiny silt can be separated with crude oil emulsion, and then be constantly deposited on electrical desalter bottom.
Meanwhile in electric dehydration electric desalting equipment operational process, it is necessary to keep the relatively stable of emulsion liquid level position, such as
The silt for being deposited on tank bottom cannot be discharged in fruit in time, then the silt constantly deposited can raising emulsion liquid level gradually,
If emulsion liquid level is excessively high or reaches high voltage electric field region, short circuit or breakdown between electrode plate will lead to, so that it is de- to jeopardize electricity
Salt equipment and the safety of raw material preprocessing device, even running.Therefore, it is necessary to periodically use back-purge system to tank bottom
Impurity carries out sewage backwash.
Existing electrical desalter back-purge system is usually in electrical desalter tank bottom setting backwash tube, backwash tube
Perhaps end has spray head spray head vertical with electrical desalter bottom or the certain angle of inclination in portion, when work backwash water flow from
Spray head sprays, and takes tank bottom silt out of electrical desalter.Due to the requirement for the treatment of capacity, the general length of electrical desalter is larger, therefore makes
Spray head quantity is more.Even if more water pumps work at the same time when carrying out backsurging operation, shape is also difficult in nozzle exit
Tank bottom sludge is pushed at required operating pressure.Although out of electrical desalter can be taken part silt, there are also very big portions
Divide and still remain in electrical desalter bottom, by long time integration, very thick sludge, partial back-washing nozzle can be formed in tank bottom
It is even buried by sludge, only partial back-washing nozzle can play a role.And the arrangement of back-purge system is to recoil
The effect washed has larger impact, the silt near back flushing nozzle be backwashed system punching get up after, electrical desalter is not discharged,
But tank bottom is fallen back to again, do not have the effect of backwash.
[utility model content]
Described in background technology to solve the problems, such as, the utility model devises a kind of electrical desalter with automatic control
Multiple branched pipes can be arranged in pot bottom, by control system to each during electrical desalter is run in back-purge system
Branch pipe is controlled, and carries out sectional flushing to electrical desalter bottom, and in gradually layer-by-layer mode one by one, tank bottom sludge is released electricity
Desalter preferably achievees the effect that sludge is discharged.The amount of water sprayed of backwash unit time, effectively control oil can be reduced simultaneously
The fluctuation of water interface, conducive to device and the long-term operation of equipment.
To achieve the goals above, the utility model uses following design structure:
A kind of electrical desalter back-purge system with automatic control, including control cabinet, control valve, backwash tube, recoil
Wash branch pipe and backwash spray head.
Wherein, backwash tube 3 is located at below tank bottom, and backwash branch pipe 4 is located above tank bottom, and backwash branch tube spacing is
200mm-1200mm, arrangement backwash spray head 5 is several on branch pipe, and backwashing spray head 5 is 10mm-400mm with tank bottom at a distance from, sprays
Head is directed toward sewage draining exit direction, issues control signal by control cabinet 1, controls the control valve 2 on each road backwash branch pipe 4, makes it
It is successively switched from far near according to away from sewage draining exit, the solid particles such as electrical desalter pot bottom sludge is finally pushed into 6 row of sewage draining exit
Electrical desalter out.
Due to using above-mentioned design structure, the utility model is had the advantages that
1, filth-discharging effect is good, due to using successively sequence-injection, so that tank bottom sludge is continuously pushed, until discharge electricity
Desalter ensure that the filth-discharging effect of this system.
2, oil water surface fluctuation is small, since filth-discharging effect is good, tank bottom sludge can be made to be discharged in time, will not be in tank bottom shape
At sludge blanket, guarantee that electrical desalter emulsion liquid level maintains more constant position.
3, backwash water amount is small, since each backwash branch pipe of this system is successively sequence-injection, in single injection event work
It need to be only the nozzle the amount of injection of the branch with backwash water, therefore compared to previous electrical desalter back-purge system when making
Water consumption is small.
4, work efficiency is high for system, since this system controls each branch using control system, total system collection
High, the ideal control function easy to accomplish at degree, and have good external interface performance, it can be achieved that remotely or on the spot manipulating.
[Detailed description of the invention]
Fig. 1 is the overall schematic of back-purge system described in the utility model；
Fig. 2 is the nozzle structure schematic diagram of back-purge system described in the utility model；
In figure: 1, control cabinet；2, control valve；3, backwash tube；4, branch pipe is backwashed；5, spray head is backwashed；6, sewage draining exit.
[specific embodiment]
By the following examples can detailed explanation the utility model, open the purpose of this utility model is intended to protect
All technological improvements in the scope of the utility model.
A kind of electrical desalter back-purge system with automatic control in conjunction with described in attached drawing 1, attached drawing 2, including control cabinet
1, control valve 2, backwash tube 3, backwash branch pipe 4, backwash spray head 5.
At work, when electrical desalter needs to be rinsed operation, signal is issued by control cabinet 1, is opened apart from blowdown
Control valves 2 on the farthest backwash branch pipes 4 of mouth 6, are that the backwash spray head 5 of the branch road is in spray regime, by farthest
The sludge of tank bottom is rushed to 6 direction of sewage draining exit, after rinsing a period of time, is issued signal by control cabinet 1, is opened branch adjacent thereto
Control valve on upper backwash branch pipe, repeats flushing operation, and so on, it is repeated.Opening from the distant to the near each
The control valve of road is rushed tank bottom sludge is gradually layer-by-layer to sewage draining exit, is rinsed every time, to guarantee the blowdown effect of electrical desalter
Fruit.Meanwhile in actual operation, it can be carried out according to the control program repeat of setting multiple.
That has been described as the preferable specific embodiments of the utility model, but the similar side in addition to this above embodiment
Formula, the arrangement including changing each branch branch pipe, this hair should be all included in by changing independent control mode of each branch etc.
Within bright protection scope.
