Description
Technical field
The invention belongs to coal gasification field, especially relate to a kind of dress of the usage on black water for entrained-flow coal gasification system
Put.
Background technology
Coal gasification is the important channel of clean coal utilization.Typical Coal Gasification Technology includes fixed bed, fluid bed, air-flow
Three kinds of bed.The efficiency of carbon con version of wherein airflow bed gasification furnace is high, and liquid lime-ash is easily drained it is easy to amplify, and coal adaptability is wide, is
The development trend of following coal gasification.
The major defect that existing gasifying process exists has: usage on black water technique equipment needed thereby is many, high cost；Heisui River enters
Easily block import during flash tank, and the Heisui River of high temperature, high flow rate forms serious washing away to the inwall of flash tank, easily causes sudden strain of a muscle
Steaming pot inwall damages.
Content of the invention
A kind of it is an object of the invention to provide ash disposal efficiency high, and the air-flow bed coal-gasification work of flash tank long service life
The usage on black water device of skill.
The technical scheme is that usage on black water device includes flash tank and heat exchange columns, flash tank is conveyed by steam
Pipeline is connected with heat exchange columns, and one end of steam pipeline is located at flash tank side upper wall, and the other end is located at heat exchange columns side lower wall, its
The feed pipe in high temperature Heisui River is arranged on the top of flash tank, and the spout of feed pipe is provided with cone-shaped hood, in cone-shaped hood and flash tank
It is provided with tubular interlayer, tubular interlayer and flash distillation top tank structure form annular chamber, flash-off steam outlet is arranged on annular chamber 6 between wall
Connect above side and with steam pipeline.
The import in high temperature Heisui River is arranged on the top of flash tank, Heisui River can be mitigated to flash tank in the face of the inwall of import
Washing away and corroding of face, simultaneously because the presence of cone-shaped hood, limits the diffusion area in HTHP Heisui River, to flash tank import
The internal face of both sides also plays protective effect.Tubular interlayer constitutes gas with flash distillation top tank structure formation annular chamber and goes out flash tank
Passage, this passage can shield the high pressure of feed pipe spout, reduce the resistance that flash-off steam goes out flash tank.
Feed pipe on flash tank can arrange 2 to 4, and is uniformly distributed on the circumference of flash drum overhead.This set
Meter can make the usage on black water amount of flash tank in interior regulation and control in a big way, convenient operation.
Flash-off steam outlet can be 1 or 2.When outlet is for 2, its Relative distribution is in the same circle of flash distillation pot sidewall
Zhou Shang.
The opening angle of cone-shaped hood is too small to increase Heisui River washing away and corrosion strength to the internal face of import faced by flash tank
Degree, the protection of the excessive tubular interlayer inwall being unfavorable for flash tank import both sides of opening.When the opening angle of cone-shaped hood is 10 °
During to 45 °, above two protective effect reaches balance, and effect is preferable.The opening angle of preferably cone-shaped hood is 15 ° to 30 °.
Further, the wall of tubular interlayer is provided with balance pipe.Balance pipe is used for the pressure reduction inside and outside surge drum clevis layer,
Prevent air velocity too fast, cause gas to carry excessive liquid secretly and enter ring cavity.
Further, 1 to 4 layer of brokenly bubble plate can be set in annular chamber, and the number of the brokenly bubble plate in every layer is 10 to 20,
And be evenly distributed on same circumference, the two ends of brokenly bubble plate are connected to the outside wall surface of tubular interlayer and the internal face of flash tank
On.Brokenly bubble plate can prevent liquid from taking a shorter way, and also act as the effect of support tube clevis layer simultaneously.
The cross section of brokenly bubble plate is curve protruding upward, the such as shape of falling v or the arcwall face that Open Side Down, and brokenly bubble plate
Curved edges are in dentation.Brokenly bubble plate can arrange 1 to 4 layer, and each brokenly bubble plate in every layer can be uniformly distributed, simultaneously on same circumference
Each layer brokenly bubble plate is staggered.The staggered brokenly bubble plate of each layer may be constructed the air flow path of complications.
When assembly of the invention is run, the HTHP Heisui River from upstream process sprays into flash tank by feed pipe, is formed
The tortuous passageway that becomes through brokenly bubble plate shape of flash-off steam from exporting out flash tank, and enter heat exchange columns and carry out heat exchange.Flash distillation
Heisui River afterwards is discharged from flash tank bottom.Flash-off steam enters heat exchange columns from the side-lower of heat exchange columns, carries out heat friendship with cold buck
Change, uncooled gas is discharged from heat exchange top of tower, buck is discharged from bottom.
The invention has the beneficial effects as follows: the angle setting of the cone-shaped hood of flash drum overhead charging and charging aperture reduces height
Super pressure-high temperature Heisui River is washed away and is corroded to flash distillation top tank structure, extends the service life of flash tank；Tubular interlayer reduces steam
Go out the resistance of flash tank；The brokenly bubble plate of setting given shape, prevents liquid from taking a shorter way, simultaneously support tube clevis layer.
