Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment of:

the utility model provides an internally mounted useless miscella dealkalize separator's processing jar, including tank storehouse 1, the surface connection of tank storehouse 1 has first hand-hole 2, the external fixed surface of tank storehouse 1 is connected with row clean mouth 3 and steam regeneration entry 4, the fixed surface of tank storehouse 1 is connected with outlet 5, tank storehouse 1 keeps away from the one side fixedly connected with inlet 6 of arranging clean mouth 3, the external fixed surface of tank storehouse 1 is connected with row steam mouth 7 and water inlet 8, the one end that tank storehouse 1 kept away from first hand-hole 2 is connected with second hand-hole 9, the inboard fixedly connected with knockout drum 10 of tank storehouse 1, the inboard of knockout drum 10 is provided with coalescence module 11, tank storehouse 1 is cylindrical shape, first hand-hole 2 comprises two parts, a part of first hand-hole 2 is the cylinder shape, another part of first hand-hole 2 is the disc shape, and rotate through the bull stick between the two parts of first hand-hole 2 and connect, net mouth 3 is the cylinder shape, steam regeneration entry 4 is unanimous with the shape of row clean mouth 3, the size of outlet 5 is greater than the size of clean mouth 3 and

steam regeneration entry

4, 6 is the size of row, the through-hole 6 is greater than the cylinder shape of the through-hole 7 and the size of the water inlet 8 of the interior connection of the steam separation of the steam outlet, inlet 11, the hollow toluene separation module, inlet is formed by the size of the cylinder shape of the hollow toluene separation mouth 7, the hollow toluene separation mouth 10.

The waste washing oil is composed of toluene, polymer, alkali liquor and the like, the mixture has the characteristics of high viscosity, easiness in emulsification and the like, when materials enter a separator and flow through a coalescence module 11, micro water drops of a dispersion phase contain alkali, wet coalescence is generated in the coalescence module 11, the alkali drops are adsorbed on fibers of a coalescence material and gradually move to fiber nodes to be coalesced and grown up, then the water drops are formed to be large enough through growth, phase aging and conversion, interfacial tension is destroyed to be desorbed, and demulsification is generated on an alkali-in-oil/alkali-in-oil structure.

The dispersed phase big water drops and the continuous phase hydrocarbon are subjected to phase inversion, in the separation area, the hydrocarbon and the water are layered in the separation area by means of the specific gravity difference, and the hydrocarbon floats upwards and sinks downwards, so that the separation of the hydrocarbon and the water is realized.

And a liquid level sensor and an on-site liquid level meter are arranged in the hydrocarbon storage area, LLL and HLL alarms are arranged, and when the liquid level reaches a designed value, the hydrocarbon is discharged through an N2 port.

And a liquid level sensor and a field liquid level meter are arranged in the water phase storage area, LLL and HLL alarms are arranged, and when the liquid level reaches a design value, water is discharged through an N6 port.

The apparatus is designed for non-full tank operation, with nitrogen pressure compensation. After the mixture passes through the coalescence module 11, a certain separation time is needed in the separation region, and when the flow rate, pressure, temperature and the like of incoming materials of each part in the separator device are changed, the pressure in the device is unstable, droplets coalesced on the fibers of the coalescence module 11 are easily dispersed, and the interface of the separation region is easily mixed up, so that the separation effect is poor.

The gas phase is generated by the gathering of a plurality of streams in the equipment, if the pressure in the equipment is changed, the gas phase particles are likely to break and gather at any time, which is equivalent to a local air flotation in the equipment, and the two-phase liquid tends to be emulsified more and is not beneficial to separation.

Once the hydrocarbon-water separation interface is damaged, the interface is reestablished, which is equivalent to restarting the equipment once.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
