Abstract
The invention relates to a novel oil-slurry scale inhibitor injection device comprising a scale inhibitor injection pipeline and an oil-slurry pipeline, wherein the scale inhibitor injection pipeline is vertical to the oil-slurry pipeline and extends inside the oil-slurry pipeline; an injection-point protecting sleeve is arranged outside the scale inhibitor injection pipeline at the vertical part of the scale inhibitor injection pipeline and the oil-slurry pipeline; a sleeve flange is arranged at the top part of the injection point protecting sleeve; an injection-line reducing flange is arranged on the sleeve flange; and the sleeve flange is tightly connected with the injection line reducing flange in a matching manner. By adopting the novel oil-slurry scale inhibitor injection device, the defects of air blisters are prevented; the production efficiency is improved; and the service life is also prolonged.
Description
Technical field
The present invention relates to a kind of petrochemical equipment, be specifically related to a kind of slurry oil scale inhibitor filing device.
Background technology
At present, the slurry oil scale inhibitor filing device on market mainly contains two kinds of structure formations.The first is that Scale inhibitors pipeline adopts socket weld to be connected with slurry oil pipeline, and is not with nozzle, the slurry oil scale inhibitor filing device of this structure is easily revealed at weld bond place, can cause whole device to stop and process leak source, have a strong impact on production, it is at any time unnecessary to cause to enterprise, the second is, the defect existing according to the first is carried out improved, at the inner nozzle that increases of slurry oil pipeline, at nozzle periphery suit stainless steel wear-resistance protective sleeve, described sheath stretches out slurry oil pipeline and is connected with its butt welding, this structure in actual use, find to have sand holes at weld, its reason is that the diluting solvent of Scale inhibitors is the aromatic solvent naphtha for approximately 200 DEG C of boiling points, need to be injected into temperature in the slurry oil pipeline of 360 DEG C, and diluting solvent is in the time encountering high temperature, can a large amount of vaporizations cause cavitation erosion, so, can produce sand holes situation at weld, and these defects can directly affect production efficiency and progress, bring great inconvenience to actual production.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, provides one to prevent sand holes defect, enhances productivity, the novel slurry oil scale inhibitor filing device of long service life.
Technical scheme: in order to solve the problems of the technologies described above; the novel slurry oil scale inhibitor filing device of one of the present invention; it comprises that Scale inhibitors injects pipeline and slurry oil pipeline; described Scale inhibitors injects pipeline perpendicular to described slurry oil pipeline and inserts into the inner portion; the Scale inhibitors injection pipeline outside of injecting pipeline place vertical with slurry oil pipeline at described Scale inhibitors is provided with decanting point protective casing; be provided with casing flange at described decanting point protective casing top; above described casing flange, be provided with and inject line reducing flange, described casing flange coordinates and is closely connected with injection line reducing flange.
Described Scale inhibitors injects pipeline, and to stretch into described slurry oil pipeline inner and to its position of center line.
The external diameter that described Scale inhibitors injects pipeline is less than described decanting point protective casing internal diameter, has gap between them.
Described casing flange is fixedly installed on described decanting point protective casing tube wall outside.
Described injection line reducing flange is arranged on described Scale inhibitors injection tube line pipeline walls outside.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the each parts of the present invention are closely connected, safe and reliable to operation, described Scale inhibitors injects between pipeline and decanting point protective casing and has gap, can avoid the generation of the defects such as sand holes, improved the work-ing life of production efficiency and device simultaneously, adopt casing flange and inject closely cooperate respectively decanting point protective casing and Scale inhibitors of line reducing flange and inject pipeline, one-piece construction is combined closely, be difficult for producing and reveal, described Scale inhibitors injects pipeline, and to stretch into described slurry oil pipeline inner and to its position of center line, make the injection direction of Scale inhibitors identical with the flow direction of slurry oil, this installs realistic service requirements.
