Description
Technical field
The present invention relates to slurry oil apparatus field, particularly a kind of slurry fouling inhibitor heater.
Background technology
At the bottom of catalytic cracking fractionating tower, slurry oil density is large, operating temperature is high, condensed-nuclei aromatics content is many and containing a certain amount of catalyst dust, in device long-term operation process, easily there is the pyrocondensation coking fouling of heavy component or the deposition fouling of solid particle, affect the heat transfer effect of slurry service and normally run.Be widely used in the slurry fouling inhibitor of slurry service at present, carry out special filling for slowing down or avoid slurry service fouling, why antisludging agent has preventing or slows down the function of slurry service fouling.And antisludging agent to add brief description of the process as follows:
Oil gas quencher is entered by reactor head high-temperature oil gas out, quench oil (containing automotive gasoline bright stock, slurry oil, recycle oil) is utilized to carry out chilling, cooled oil gas by quencher top out, gas-liquid heat exchange fractionation is carried out in the bottom entering fractionating column, and bottom quencher, slurry oil out returns fractionating column.Because gum level in fractionation column base slurry oil is comparatively large, and containing a certain amount of catalyst, in order to prevent it from depositing or fouling in pipeline, affect pipeline heat exchange, or blocking pipe, therefore need in slurry oil pipeline, to inject antisludging agent continuously.
In actual production, antisludging agent injection pipeline is starched pipeline with crude oil and is adopted socket weld to be connected, and makes weld bond occur leaking for a long time, and causing stops processes leak source, has a strong impact on production, causes unnecessary loss to enterprise.The reason key factor of leak source is caused to have: one is containing a small amount of catalyst flowing wearing and tearing in slurry oil, comparatively serious to washing away of pipeline, gas corrosion phenomenon is produced in addition owing to running into high temperature slurry oil after the injection of normal temperature slurry fouling inhibitor, and the part of originally welding is just more fragile, so be easy to form leak source, make troubles to production.
Produce cavitation in order to avoid cryogenic media (antisludging agent) runs into high-temperature medium (slurry oil) leakage is caused to washing away of equipment, someone and also do not have in the market and carry out for antisludging agent the special equipment that heats, it is more than 280 degrees Celsius that common firing equipment is difficult to realize reaching temperature before antisludging agent adds again.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of slurry fouling inhibitor heater is provided, by arranging rational structure, the heating of antisludging agent can be realized fast, ensure that antisludging agent adds successional while, run into high temperature slurry oil after the slurry antisludging agent after preheating is injected and reduce cavitation, realize the sustainability of producing, reduce the loss, reduce costs.
To achieve these goals, the technical scheme of patent employing of the present invention:
A kind of slurry fouling inhibitor heater, comprise housing 4, antisludging agent entrance 1, preheating group 2, liter heat group 3, heat-flash group 5, antisludging agent outlet 6, it is characterized in that: antisludging agent entrance 1, preheating group 2, liter heat group 3, heat-flash group 5, antisludging agent outlet 6 connect successively, preheating group 2, liter heat group 3, heat-flash group 5 are positioned at housing 4, antisludging agent entrance 1, antisludging agent outlet 6 is positioned at outside housing 5, and described preheating group 2, liter heat group 3, heat-flash group 5 are solenoid structure.
Further illustrate as of the present invention, in described preheating group 2, liter heat group 3, heat-flash group 5, be equipped with heating spool 2-1.Heating spool is provided with in preheating group 2 of the present invention, liter heat group 3, heat-flash group 5 solenoid structure, heating spool is that in existing seamless metal pipe, (carbon steel pipe, titanium pipe, stainless steel tube, copper pipe) loads heating wire, after the magnesia powder of thermal conductive resin and insulating properties is filled up in gap, the draw forms, and is reprocessed into required various type shapes.The heating spool thermal efficiency is high, and mechanical strength is good, has good adaptability to rugged environment, can be used for the heating of various liquid and acid-alkali salt, and the METAL HEATING PROCESS simultaneously also adapting to LMP is dissolved (lead, zinc, tin, babbit).
Further illustrate as of the present invention, antisludging agent can be heated to 95 ~ 100 DEG C by preheating group 2, and rise heat group 3 and antisludging agent can be heated to 200 ~ 210 DEG C, antisludging agent can be heated to 280 ~ 290 DEG C by heat-flash group 5.
Further illustrate as of the present invention, this heater also comprises inlet valve 8 and outlet valve 7, and inlet valve 8 is between antisludging agent entrance 1 and preheating group 2, and outlet valve 7 is between antisludging agent outlet 6 and heat-flash group 5.
Beneficial effect of the present invention:
Spirality of the present invention heating road is according to according to hydrodynamics and thermo-dynamic principle, maintain the stable of heat engine system, heat medium is avoided to form eddy current or turbulent flow when heat exchange, flow according to the set flow direction when ensureing heat medium on-line heating, increase flow velocity, under the various operating modes of heating system, realize the space-time structure of stably heat exchange.Hanker in reality raw adding, first antisludging agent is heated to 95 ~ 100 DEG C by preheating group 2, then through rising heat group 3, antisludging agent is heated to 200 ~ 210 DEG C, and antisludging agent is heated to 280 ~ 290 DEG C by last heat-flash group 5, and the antisludging agent after heat-flash can enter in slurry oil pipe.The present invention is by arranging rational structure, the heating of antisludging agent can be realized fast, ensure that antisludging agent adds successional while, run into high temperature slurry oil after slurry antisludging agent after preheating is injected and reduce cavitation, use safety, convenience, scientific and reasonable, be convenient to promote the use of, realize the continuity of producing.
