Description
Technical field
The utility model relates to pitch oxidation and produces the equipment used oxidizing tower, is specially the air water combination decollator that a kind of pitch oxidation is used
Background technology
Petroleum pitch is highly condensed polynuclear hydrocarbon class mixture.Normal temperature is unformed black solid down, and section has light, is used to spread highway pavement, material of construction, wood preservation, insulating material etc. in a large number.The raw material of oxidized bitumen is the vacuum residuum of crude distillation and the pitch of heavy oil solvent deasphalting unit gained.Pitch oxidation is softening temperature is low, penetration degree and big vacuum residuum or solvent deasphalting or their mixture of temperature sensitivity; Under the certain temperature condition, feed oxidation wind (air) and carry out oxidation; Its composition is changed; Softening temperature raises, and penetration degree and temperature sensitivity reduce, to reach pitch specification index and use properties requirement.
Early stage oxidation furnaces is the single kettle type tower, has developed into the placed in-line continuous oxidized bitumen technology of single tower or multitower at present.Raw oil is heated to 260-280 ℃ of entering oxidizing tower through process furnace.Blast pressurized air in the tower and carry out vigorous stirring, carry out oxidation, the oxidized bitumen of being produced gets into the finished product jar, is sent to moulding, packing then, and the product that obtains mainly is a building asphalt.Produce the shallow degree oxidizing process of the general employing of road bitumen, single tower operate continuously.The residual oil inlet temperature of stabilizer is 190-210 ℃.Different with raw material, the pitch label of production is different, and operational condition also is not quite similar.
The performance index of petroleum pitch mainly contain penetration degree, softening temperature and ductility.The supply of oxidation wind is very heavy to the penetration degree influence of oxidized bitumen.Therefore the feed rate of oxidation wind and the distribution in oxidizing tower are very crucial to the influence of oxidizing reaction in the tower.This just is the very high requirement of design proposition of oxidizing tower internal structure.Oxidation wind sparger is generally comb formula structure or nozzle-type structure in traditional oxidizing tower.Production well is stopped up in the easy coking of this comb formula structure, and life cycle is short, and flange-interface is many, the maintenance trouble, and blast main is too heavily carried inconvenient; And the air outlet opening total area of nozzle-type structure is less than the sectional area of blast main, the not too big change of its result of use.This traditional tower inner structure can not make the mass transfer effect between oxidation wind and the residual oil poor preferably for oxidation wind provides equally distributed chance.Produce qualified oxidized bitumen through this traditional oxidizing tower, often need feed a large amount of oxidation wind, increase load for follow-up vent gas treatment operation, increase the discharging of incinerator, increase atmospheric pollution.Problems such as in a word, existing pitch oxidation tower long-term existence oxidation wind utilization ratio is low, and the pitch oxidation process is slow, and the pitch oxidation time is long.
The utility model content
The utility model technical problem to be solved provides the air water combination decollator that a kind of pitch oxidation is used; It passes through to improve existing structure of distributor and realizes efficient mass transfer between the interior gas-liquid phase of tower; Improve the utilization ratio of oxidation wind, reduce the discharging of subsequent handling incinerator, realize energy-saving and emission-reduction.
Solve the problems of the technologies described above the technical scheme of employing:
The air water combination decollator that a kind of pitch oxidation is used, it comprises technology adapter that extends in the oxidizing tower and the SV type static mixer that is connected with the technology adapter through flange; And extend the dendroid sparger house steward place the oxidizing tower shaft core position through elbow; On the dendroid sparger house steward arm is set, the arm end connects concentric sloper through a pipe bend.
Said SV type static mixer is the air water static mixer.It is two that number is set on standpipe and level pipe.
Support beam is set in the oxidizing tower, and said arm is a bilayer structure, is fixedly set on the support beam through pipe clamp, and said dendroid sparger house steward end is provided with pipe cap.
The beneficial effect of the utility model: adopt technique scheme, realized efficient mass transfer between gas-liquid mutually in the tower in the pitch oxidation tower, improved the utilization ratio of oxidation wind, shortened oxidation time through double-deck dendroid sparger is set.Air water is through high mixed and dispersion simultaneously; Be evenly distributed at the bottom of the tower, avoided the bumping that causes because of water filling, realized pitch oxidation tower liquid phase water-filling function; Strengthen the interior gas-liquid mass transfer heat-transfer effect of liquid phase and taken reaction heat away; Improve oxidizing reaction temperature, increase oxidizing intensity, improved the asphaltic products. quality.In addition, through this combination of air water efficiently decollator, also improved the flexibility of pitch oxidation tower to different material.
