Description
Technical field
The energy development of the utility model category and environmental technology field, more particularly, to a kind of coal gasification reduction by-product high temperature
Oil gas dust removal separation apparatus.
Background technology
Compared with coal gasification and liquefaction technology, coal carbonization can obtain coal gas under the conditions of relatively mild, tar and
Semicoke is a kind of both economical coal transformation routes.Coal carbonization process generally carries out in distillation apparatus such as gas retort, coal
The gas-phase product generated in retort process is commonly referred to as " dry distillation gas ", wherein contain a certain amount of dust, if not removed,
The quality of coal gas and tar product can be not only reduced, but also influences the stable operation of distillation system.In addition, also containing in dry distillation gas
It is in gaseous tar to have.Cooling treatment is purified to dry distillation gas, forbids distinct methods occurred.
China's oil starvation, few gas, rich coal energy resource structure feature be doomed AND ENERGY RESOURCES CONSUMPTION IN CHINA will be for a long time based on coal, coal at present
Mine mechanical mining degree is relatively high, and lump coal only accounts for 30% or so, and a large amount of cheap fine coal in major coal place of production can not be effective
Utilization.
Semi-coke, also known as semicoke, coke, structure are bulk, and granularity is generally in 3mm or more, and color is in light/dark balance, currently, blue
There are mainly two types of specifications for charcoal:When soil refining semi-coke, second is that mechanism semi-coke；Although the semi-coke of two kinds of specifications is same high-quality
Cleaned coal is refined, but because the difference of production technology and equipment, cost and quality are also made a world of difference.Wherein good semi-coke production
Shenmu County and Fugu in Shaanxi.
The pyrolysis of coal, like the air-distillation process of tar, if not dedusting, that is difficult oil and water, oil and oil separation
It comes.This petroleum vapor recovery mode is conducive to oil quality raising, is also beneficial to enterprise oil at three kinds of oil of heavy, medium and light
Economic value improves, and is also beneficial to follow-up oil product processing.After carrying wax such as heavy oil, add hydrogen formed heavy diesel fuel component, or directly as
Industrial fuel oil, or directly as carbon black raw oil etc.；Light oil is the highest oil product of economic value, is gasoline fraction, passes through letter
Single rectifying adds hydrogen, can get solvent naphtha and premium.Oil-water separation, dust removing effects are directly related to oil quality,
It is particularly significant to tar following process.
Patent CN96207496.9 is a kind of rotary furnace formula retort gas generator, it is removed using cyclone separating tube
The dust of dry distillation gas.Patent CN921000912.7 is a kind of method and apparatus producing dry distillation gas, and dry distillation gas removes
Dirt device is cyclone separator or inertia separator.But it is found in putting into practice, the heavy tar and dust of generation attach to whirlwind point
From device inner wall, cyclonic separation efficiency is not only caused to decline, but also influences the longtime running of system.
Utility model content
For the deficiencies in the prior art, the utility model provides and a kind of coal gasification reduction by-product high temperature oil
Gas dust removal separation apparatus, high-temperature oil gas is from air inlet by the first valve and metal compensator, 90 ° of turnings are vertical to flow down, warp
Adequately rebuffed and turbulent flow is crossed, part dust is gathered along wall and fallen with gravity；High-temperature oil gas is fully slow in bottom of box buffering area
After punching, half-turn is sailed against the current, and high-temperature oil gas is under the interception of the staggered L-type steel of multilayer, and curve rises, a large amount of dust
It gathers in L-type steel bottom and both sides, when the dust gravity of accumulation is more than the sum of the buoyancy that adhesion strength and air-flow rise, both fell into
The bottom of box is fallen under baffle effect in helical structure device, and dust is discharged by helical structure from discharge port；High temperature oil
After gas is fully collided with L-type steel, go out from the gas outlet for being equipped with metal compensator and the second valve, into next process.
Specific technical solution used by the utility model is as follows：
The upper end side of the discharge port being connect including babinet and with the babinet bottom end, babinet connects air inlet, another
Side connects gas outlet, it is characterised in that：The babinet includes：It is sealingly mounted at the helical structure of box house bottom end, and
Drive the motor of the helical structure；L-type steel of the parallel and staggered installation in box house；It is sealingly mounted at box house bottom end two
The baffle of side.
The L-type steel is arranged in inverted V-shape, and the baffle is in inverse Ba type structure.
In the utility model, high-temperature oil gas is typically from coal carbonization gasification reduction apparatus, such as known in the art
Reaction kettle.Depending on the operating condition of reaction kettle, the temperature for leaving the dry distillation gas of reaction kettle outlet is generally 400~850 DEG C,
Wherein contain the dust such as coal dust, ash largely carried secretly to grade and at a high temperature of reaction kettle exit in gaseous tar.
According to the difference of boiling point, it is heavy tar and tar light oil that these tar, which can be divided into roughly, and wherein heavy tar refers in coal
Tar mid-boiling point is higher than 360 DEG C of substance, and tar light oil refers to the substance that coal tar mid-boiling point is less than 360 DEG C.
360 DEG C~600 DEG C of dust-laden high-temperature oil gas can be reduced to 360 DEG C of dedustings below, except heavy tar by babinet
High-temperature oil gas, 90% or more dust granule removal rate, 80% or more heavy tar removal rate flow specifically with the flow of air inlet
Speed, volume of cylinder etc. are related.The dust removal separation apparatus is simple in structure, secured, abrasion is small, long lifespan, integral installation convenience.
The babinet is generally rectangular parallelepiped structure, also includes cylindrical structure, the advantages of rectangular parallelepiped structure is installation side

Root, specifically by the number for the treatment of capacity, air velocity and dust burdening, the volume of babinet, depending on height.
In the present embodiment, discharge port 8, air inlet 9 is separately installed with metal compensator 11 at gas outlet 10；Air inlet 9,
The first valve 12 and the second valve 13 are separately installed at gas outlet 10.The both sides and top of babinet 1 are equipped with access hole 4；
The specific operation process of above-mentioned apparatus is as follows：Enter from the dust-laden high-temperature oil gas that reaction kettle comes out from air inlet 9, beats
Open the first valve 12, along 1 side of babinet, by baffle barrier at a cuboid channel slowly take advantage of a situation and down toward 1 bottom of babinet,
It is contacted with bottom or 1 wall of babinet contacts, then again slowly and up to L-type steel 2, under the L-type steel 2 in babinet 1 acts on, high temperature oil
Make roundabout leave with rage, dedusting goes out to enter work except the high-temperature oil gas of heavy tar using the second valve 13 from gas outlet 10
Sequence；When 1 inside L-type steel 2 of babinet accumulation carbon black dirt accumulation to it is a certain amount of when, the gravity of itself be more than dust adhesion strength with
When airflow buoyancy, freely falling body is to 1 bottom of babinet, under the action of in inverse Ba type structural baffles 3, is freely concentrated into one
Line, then the translator 5 by being constantly in working condition have axis spiral 6 to be exported from discharge port 8, can input next process..
The foregoing is merely the preferable implementation examples of the utility model, are not intended to limit the utility model, all in this reality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
