Abstract
The utility model relates to a slurry oil scale inhibitor filing device, which fundamentally solves the problems of severe influence on production and the like caused by leakage point treatment through machine halt of the whole device because of easy leakage of welding opening parts caused by carrying and insertion welding connection adopted by a scale inhibitor pipeline and a slurry oil pipeline in the existing process. The slurry oil scale inhibitor filing device comprises a scale inhibitor filling pipeline and has the technical scheme of also comprising a spray nozzle arranged inside the slurry oil pipeline, wherein a stainless steel wear-resistant protection sleeve is sheathed on the outer periphery of a spray nozzle, the top end of the protection sleeve extends out from the slurry oil pipeline and is in butt welding connection with the slurry oil pipeline, a connecting pipeline of the spray nozzle extends out of the top end of the protection sleeve and is connected with the scale inhibitor filling pipeline through a flange, and the spraying direction of the spray nozzle is the same as the flowing direction of the slurry oil in the slurry oil pipeline. The slurry oil scale inhibitor filing device has the advantages that the structure is reliable, the service life is long, and the like. The slurry oil scale inhibitor filing device is applicable to devices for preparing ethylene through cyclic catalysis cracking (CPP).
Description
Technical field
The utility model relates to petrochemical equipment, particularly a kind of slurry oil Scale inhibitors injection device that is used for catalytic pyrolysis system ethene (CPP) device.
Background technology
Catalytic pyrolysis system ethene (CPP) device adopts the patented technology of China Petroleum ﹠ Chemical Corporation Research Institute of Petroleum, it is the new technology that on the basis of catalytic pyrolysis (DCC) technology, develops, this technology is raw material with the long residuum, adopt the parallel catalytic pyrolysis technology of two devices (reactor, revivifier), its purpose product changes hold concurrently product ethene and propylene into by propylene.
Its brief description of the process is as follows: the high-temperature oil gas of being come out by reactor head enters the oil gas quencher, utilize quenching oil (containing stock oil, slurry oil, recycle stock) to carry out chilling, cooled oil gas is come out by the quencher top, the gas-liquid heat exchange fractionation is carried out in the bottom that enters separation column, and the slurry oil that comes out in the quencher bottom returns separation column.Owing to gum level in the slurry oil at the bottom of the separation column is bigger, and contain a certain amount of catalyzer, in pipeline, deposit or fouling, influence the pipeline heat exchange for preventing it, or blocking pipe, therefore need in the slurry oil pipeline, inject Scale inhibitors continuously.
Yet former technology Scale inhibitors pipeline adopts socket weld to be connected with the slurry oil pipeline, and is not with nozzle (as shown in Figure 1), cause longly then three months, short then one month, the weld bond place will reveal, cause whole device to stop and handle leak source, have a strong impact on production, cause unnecessary loss to enterprise.Analyze reason: the one, contain the mobile wearing and tearing of a spot of catalyzer in the slurry oil, comparatively serious to washing away of pipeline, in addition,, normal temperature slurry oil Scale inhibitors produces reasons such as cavitation erosion owing to running into the high temperature slurry oil at the inlet place.
Summary of the invention
The purpose of this utility model is for more reasonably slurry oil Scale inhibitors injection device of a kind of structure design is provided, fundamentally solving in the existing technology Scale inhibitors pipeline adopts socket weld to be connected the weld bond place that is caused with the slurry oil pipeline easily to reveal, cause whole device parking processing leak source, have a strong impact on problems such as production.Have advantages such as reliable in structure, long service life.
The technical solution of the utility model is: this slurry oil Scale inhibitors injection device, comprise that Scale inhibitors injects pipeline, its technical essential is: also comprise the nozzle that is arranged at slurry oil pipeline inside, described nozzle periphery is set with the wear-resisting sheath of stainless steel, described sheath top is stretched out described slurry oil pipeline and is connected with its butt welding, the connection line of described nozzle stretches out described sheath top and utilizes flange and described Scale inhibitors to inject pipeline and is connected, and the injection direction of described nozzle is identical with the flow direction of slurry oil in the described slurry oil pipeline.
Advantage of the present utility model and positive technique effect are: often ftracture for solving slurry oil Scale inhibitors decanting point; cause short problem of stopping of the device cycle of operation; the utility model is provided with nozzle in slurry oil pipeline inside, and prevents that at the outside suit of nozzle slurry oil from being protected the sheath of nozzle wear.The utility model is owing to adopt sheath protection facility to avoid slurry oil to nozzle abrasion; the middle part that is in equipment because of nozzle has also been avoided cryogenic media to run into the high-temperature medium cavitation erosion washing away of equipment has been caused leakage; the life cycle of whole injector arrangement was extended to more than 1 year by original 3 months; whole device is no longer revealed because of weld bond and is caused unnecessary parking, has created huge economic benefit for enterprise indirectly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation sketch that former technology Scale inhibitors pipeline is connected with slurry oil pipeline employing socket weld before improving;
Fig. 2 is a structural representation sketch of the present utility model.
Sequence number explanation among the figure: 1 Scale inhibitors injects pipeline, 2 weld bonds, 3 slurry oil pipelines, 4 flanges, 5 sheaths, 6 nozzles.
To be described in further detail utility model by example below, but following example only is the utility model example wherein the rights protection scope of not representing the utility model and being limited.
Embodiment
According to Fig. 1-2 the utility model is described in detail.This slurry oil Scale inhibitors injection device comprises that Scale inhibitors injects pipeline 1, and wherein: also comprise the nozzle 6 that is arranged at slurry oil pipeline 3 inside, nozzle 6 peripheries are set with the wear-resisting sheath 5 of stainless steel.Nozzle 6 makes the position of nozzle 6 be in slurry oil pipeline 3 middle parts according to the injection rate size, and the injection direction of nozzle 6 is identical with the flow direction of slurry oil in the slurry oil pipeline 3.
The utility model can be applicable to the catalytic pyrolysis device, and can normally use under following processing condition: Scale inhibitors injection rate: 0.06 ~ 0.09kg/t slurry oil; Slurry oil temperature: 300 ~ 320 ℃.
Include the wear-resisting sheath 5 of stainless steel owing to adopt, its wear resistance significantly improves, and the position of nozzle 6 is in the equipment middle part, avoided the cavitation erosion problem of former nozzle, life cycle has extended to more than 1 year by original 3 months, whole device has been avoided unnecessary parking loss, helps to improve the economic benefit of whole catalytic pyrolysis device.
