Abstract
The utility model relates to a novel oil pulp scale inhibitor injection device comprising a scale inhibitor injection pipeline and an oil pulp pipeline, wherein the scale inhibitor injection pipeline is vertical to the oil pulp pipeline and extends inside the oil pulp 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 pulp pipeline; a sleeve flange is arranged at the top part of the injection point protecting sleeve; an injection line reducing flange is arranged above the sleeve flange; the sleeve flange is tightly connected with the injection line reducing flange in a matching manner. By adopting the novel oil pulp scale inhibitor injection device, the defects of air blisters are prevented; the production efficiency is improved; the service life is also prolonged.
Description
Technical field
The utility model relates to a kind of petrochemical equipment, is specifically related to a kind of slurry oil Scale inhibitors injection device.
Background technology
At present, the slurry oil Scale inhibitors injection device on the market mainly contains two kinds of structure formations.First kind is, the Scale inhibitors pipeline adopts socket weld to be connected with the slurry oil pipeline, and is not with nozzle, the slurry oil Scale inhibitors injection device of this structure is revealed easily at the weld bond place, can cause whole device to stop and handle leak source, have a strong impact on production, it is at any time unnecessary to cause to enterprise; Second kind is, defective according to first kind of existence is carried out improved, at the inner nozzle that increases of slurry oil pipeline, at the wear-resisting sheath of nozzle periphery suit stainless steel, described sheath stretches out the slurry oil pipeline and is connected with its butt welding, this structure in actual use, there are sand holes in discovery at weld, and its reason is that the diluting solvent of Scale inhibitors is to be the about 200 ℃ aromatic solvent naphtha of boiling point, need be injected into temperature in 360 ℃ slurry oil pipeline, and diluting solvent is when running into high temperature, can a large amount of vaporizations cause cavitation erosion, so, the sand holes situation can be produced at weld, and these defectives can directly influence production efficiency and progress, bring great inconvenience to actual production.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, a kind of sand holes defective that prevents to be provided, enhance productivity, the novel slurry oil Scale inhibitors injection device of long service life.
Technical scheme: in order to solve the problems of the technologies described above; a kind of novel slurry oil Scale inhibitors injection device described in the utility model; 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 and the vertical place of slurry oil pipeline at described Scale inhibitors is provided with the decanting point protective casing; be provided with casing flange at described decanting point protective casing top; be provided with above described casing flange and inject the line reducing flange, described casing flange cooperates with injection line reducing flange and closely is connected.
Described Scale inhibitors injects pipeline, and to stretch into described slurry oil pipeline inner and to its position of center line.
Described Scale inhibitors injects the external diameter of pipeline less than described decanting point protective casing internal diameter, has the 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 utility model compared with prior art; its remarkable advantage is: each parts of the utility model are closely connected; safe and reliable to operation; described Scale inhibitors injects between pipeline and the decanting point protective casing and has the gap; can avoid generation of 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; make one-piece construction combine 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 that the flow direction of the injection direction of Scale inhibitors and slurry oil is identical, this installs realistic service requirements.
