According to the oil slurry antifouling agent injecting device disclosed by the invention, through double actions that an antifouling agent is heated in advanced by heat of the oil slurry pipe and a thickened module is added in a welding part for stabilizing, leakage caused by the flushing of a low-temperature medium on equipment due to the cavitation of a high-temperature medium is avoided, and production continuity is achieved.
Description
Technical field
The present invention relates to slurry oil apparatus field, particularly a kind of slurry oil scale inhibitor filing device being provided with preheating structure.
Background technology
Catalytic cracking fractionating tower base oil pulp density is big, operation temperature is high, condensed-nuclei aromatics content many and urges containing a certain amount of
Agent dust, easily the pyrocondensation coking fouling of heavy component or the deposition of solid particle during device long-term operation
Fouling, the heat transfer effect of impact slurry service is run with normal.Be now widely used for the slurry fouling inhibitor of slurry service it is simply that
Slow down or avoid slurry service fouling specially to be filled, why antisludging agent has prevents or slow down slurry service knot
The function of dirt.And the addition brief description of the process of antisludging agent is as follows：
Enter oil gas quencher by reactor head high-temperature oil gas out, using quench oil（Containing automotive gasoline bright stock, slurry oil,
Recycle oil）Carry out chilling, by quencher top out, the bottom of entrance fractionating column carries out gas-liquid heat exchange and divides the oil gas after cooling
Evaporate, quencher bottom slurry oil out returns fractionating column.Because in fractionation column base slurry oil, gum level is larger, and containing certain
The catalyst of amount, in order to prevent it from depositing or fouling in pipeline, affects pipeline heat exchange, or blocking pipeline is it is therefore desirable to connect
Continue the injection antisludging agent in slurry oil pipeline.
In actual production, antisludging agent injection pipeline is connected using socket weld with crude oil slurry pipeline, makes for a long time
Obtain weld bond and leakage occurs, cause parking process leak source, have a strong impact on production, cause unnecessary loss to enterprise.Cause Lou
The reason put key factor has：One is to contain a small amount of catalyst flowing abrasion in slurry oil, more serious to washing away of pipeline, separately
Run into high temperature slurry oil after the outer injection due to room temperature slurry fouling inhibitor and produce gas corrosion phenomenon, and the part originally welded is just more crisp
Weak, so being easily formed leak source, make troubles to production.
Content of the invention
Present invention aim to overcome that the deficiencies in the prior art, provide a kind of slurry oil scale inhibitor filing device, by setting
Rational structure, weakens the impact to production of antisludging agent cavitation in adition process, improves the seriality producing and keep away
Exempt from unnecessary production loss.
To achieve these goals, the technical scheme that patent of the present invention adopts：
A kind of slurry oil scale inhibitor filing device being provided with preheating structure, this device includes antisludging agent injection pipeline 1, is placed in resistance
The nozzle 4 at pipeline 1 terminal port is injected in dirty agent, and described nozzle 4 stretches in slurry oil pipe 6, nozzle spray direction and described slurry oil pipe 6
The flow direction of middle slurry oil is identical, and this device also includes slurry fouling inhibitor preheating structure, and described slurry fouling inhibitor preheating structure is
Antisludging agent injects the prolongation of pipeline 1, and prolongation is the spiral pipeline 2 being close to outside slurry oil pipe 6.
Further illustrating as the present invention, described antisludging agent injects and is provided with outside the entrance of pipeline 1 injection slurry oil pipe 6
Welding thickeies module 3.
As further illustrating of invention, between described spiral pipeline 2 and injection slurry oil pipe 6, it is provided with valve 5, valve 5
Near spiral pipeline 2 and slurry oil pipe 6 weld.
In present invention slurry fouling inhibitor process injection in actual production, antisludging agent first passes around spiral in entrance slurry oil pipe
Injection pipeline 2, spiral injection pipeline 2 be wrapped on slurry oil pipeline, the heat on available slurry oil pipeline is carried out to antisludging agent
It is preheated to 280 DEG C about（In general slurry oil pipe, the temperature of slurry oil is 300 ~ 320 DEG C）, antisludging agent after preheating enter slurry oil pipe with
Slurry oil contacts, and because the temperature difference is little, substantially reduces the generation of cavitation phenomenons, and passes through to thicken setting of module on slurry oil pipe
So that the seam tube wall after welding thickeies, cavitation is difficult to carry out corroding by weld produce leak source meter, in actual production,
Can be as needed in the case that production pressure to be larger, the superfluous gas excluding in pipe opened by the exhaustor of available cap sequence
Press the seriality it is ensured that producing, thus playing the effect of protection slurry oil pipe.
Beneficial effects of the present invention：
The design is preheated to antisludging agent in advance using heater and weld has structure thicker to consolidate dual work
With, it is to avoid cryogenic media runs into high-temperature medium cavitation to be caused to reveal to washing away of equipment, and present configuration is simple, using peace
Entirely, conveniently, scientific and reasonable, it is easy to promote the use of.
