Description
Technical field
The present invention relates to heat conduction oil treatment equipment field, more particularly to a kind of conduction oil cleaning treatment system.
Background technology
Conduction oil is a kind of the heat that fuel combustion is produced can be indirectly transferred to the Hydrocarbon Organic of heating equipment.It has heat transfer efficiency height, can easily be accommodated control temperature, investment low advantage corrosion-free to equipment, is widely used in the industry-by-industries such as petrochemical industry, papermaking weaving, Aero-Space as a kind of excellent organic heat-carrying agent.Conduction oil works at high temperature all the year round as a kind of organic compound, is easily oxidized in heating process, and oil product acid number increases under high temperature and rate of change is larger.Easily occur thermal cracking when temperature in use is at 300~400 DEG C, in pipeline, equipment inner wall carbon deposit, influence heat transfer efficiency, accelerate conduction oil ageing failure, also make body of heater, pipeline hot-spot, damage equipment and jeopardize personal safety.Burnt matter is formed after conduction oil deterioration to be attached on heating furnace tube wall, is not only reduced heat transfer efficiency, heat transfer system can also be resulted in blockage.
Therefore it provides a kind of heat conduction oil treatment system, easily causes the gum asphalt of coking from conduction oil is removed in root, work efficiency is improved, purified treatment cost is reduced, as current urgent problem.Prevent the common method of heat conduction deterioration of oil and system jams from having following several at present：
(1) heat flow rate per unit area is suitably reduced, rate of heat flow is improved, reduces heating caliber, coking speed, prolonging service life of heat transfer oil can be so reduced, but conduction oil coking can not be prevented, problem can not be solved from root, and appropriate amount is provided without valid data, it is not easy to operate.
(2) mechanical decoking method：This method is fairly simple, scrapes off coking on tube wall by plastics bullet.But this method can not be fully erased clean by boiler tube, particularly it is more difficult to remove in heat-conducting oil furnace coil portions and elbow bend part.In addition, plastics bullet rapid wear boiler tube or is blocked by boiler tube when high speed rotates.
(3) high pressure water impact coke cleaning method：When boiler tube is all blocked, water under high pressure (general 85~100MPa) is poured in boiler tube, makes coking in boiler tube disengage to come with boiler tube.But water under high pressure equipment price is expensive, secondly during coke cleaning need to also on boiler tube scarfing, fettling pipe again after Jiao is taken out, damage boiler tube.In addition, water under high pressure is in elbow, hydraulic pressure is decreased obviously, and can reduce coke cleaning ability.
(4) boiler tube method is changed：This method is commonplace, and boiler tube is scrapped, and more renews pipe.But this method quantities is larger, time-consuming, laborious and expensive.
(5) alkali cleaning and pickling two-step method：Alkali cleaning, pickling two-step method cleaning are used for hot Media Oven and pipeline carbon deposit, have the advantages that cleaning rate is high, cleaning temperature is relatively low, nontoxic, cleaning cost is low.Though the method can remove dirty layer, process-intensive has acid and alkali corrosion, shortens service life of a machine, can cause secondary pollution, and to be carried out in the case of parking, influence production.
(6) ablution is dissolved：Cleaning agent cleansing power is strong, reusable, but cleaning agent tool volatility, and security is low, and cost is high.
(7) complex cleaning and washing agent ablution：Cleaning agent can crush effectively, scattered carbon deposit, also can efficiently dissolved organic carbon hydrogen compound, technique is simple, substantially corrosion-free to equipment.But this method can cause secondary pollution, and must be cleaned in the case of parking, influence production.
(8) organic additive ablution：This method technique is simple, cost-effective.But follow-up filtration processing equipment is needed, and the continuation of coking can not be prevented to generate.
