Description
Technical field
A kind of the present invention relates to smoke limestone-gypsum wet desulphurization equipment field, more particularly to fume desulfurating absorption tower.
Background technology
Limestone-gypsum wet desulfuration technology is widely used in flue gas desulfurization.Absorption tower is limestone gypsum wet
Most important part in desulphurization plant.Lime white enters absorption tower and is stored in absorption tower bottom, and lime white is extracted by spray pump
To absorption tower top and under spray thrower spray；Flue gas enters absorption tower and flows up, and the SO2 in flue gas is inhaled by lime white
Receive, then flue gas is discharged absorption tower and enters demister.Absorption tower bottom is passed through oxygen, absorb the lime white of SO2 again with oxygen
Reaction generates Gypsum Fibrosum.
Often there is fouling in existing Limestone-gypsum Wet Flue Gas Desulfurization Process equipment, and main fouling region has：Absorption tower inlet/outlet pipe
Road, demister and absorption tower bottom.The harm that fouling is produced has：First, fouling at pipeline, nozzle, the tubing pressure loss increase
Greatly, gas-liquid flow reduction, the system of ultimately resulting in normally cannot run.2nd, demister fouling, can change distribution and office's gas of flue gas
The flow velocity of body, causes demister efficiency to decline, if processing not in time, demister is caused desulfurization to stop transport by dirty be collapsed.3rd, absorb
Tower bottom fouling, causes pump inlet and the blocking of Gypsum Fibrosum outlet, affects the normal use of pump, cause system to be stopped when serious
Fortune.
Content of the invention
The technical problem to be solved in the present invention is：A kind of less scaling fume desulfurating absorption tower is provided.
Technical scheme for the employing that solves the above problems is：Fume desulfurating absorption tower includes tower body, injection apparatus and stirring
Device；Injection apparatus include slip extraction tube and and the shurry pump of the shurry pump outside tower body and slip pump inlet connection
The slip playpipe of outlet connection, slip extraction tube and slip playpipe extend into bottom in tower body；Agitating device includes position
In four agitators of tower body bottom, four agitator circumference array centered on tower body axis, agitator are included positioned at tower body
Outside motor and the stirring vane inside tower body, motor are connected with stirring vane.
It is further：Slip playpipe includes at least two ejiction openings.
The invention has the beneficial effects as follows：Injection apparatus and agitating device are stirred can the serosity at absorbing tower bottom
Mix, prevent serosity from precipitating, so as to avoid absorbing tower bear building-up dirt.
Description of the drawings
Fig. 1 is fume desulfurating absorption tower structural representation；
It is labeled as in figure：Tower body 1, injection apparatus 2, shurry pump 2-1, slip playpipe 2-2, slip extraction tube 2-3, ejection
Mouth 2-4, agitator 3, motor 3-1, stirring vane 3-2, lime white input pipe 4, lime slurry pump 5, oxygen input tube 6, oxygen pump
7th, spray pump 8, spray slurry pipe 9, spray thrower 10.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Pipeline, demister is imported and exported to absorption tower and is absorbed after tower bottom scaling cause is analyzed show that reason is as follows：
First, when desulphurization system is stopped transport, in time pipeline is not cleaned；2nd, dust pelletizing system inefficient, part dust enter desulfurization system
System；Mist eliminator flushing system is not normally run；3rd, absorbing tower prime cement liquid precipitate.
Following measures can be taken for reason one and two：First, rinsed well when serosity pipeline is stopped transport in time；2nd, improve and remove
The efficiency and reliability of dirt system；3rd, mist eliminator flushing water pressure is improved, and the frequency and time fortune is rinsed in strict accordance with rule of operation
OK.
Appropriate reconstruction can be carried out to fume desulfurating absorption tower for reason three, the transformation is present disclosure, specifically
As follows：Fume desulfurating absorption tower includes tower body 1, injection apparatus 2 and agitating device；Injection apparatus 2 are included outside tower body 1
Slip extraction tube 2-3 and the slip playpipe being connected with shurry pump 2-1 outlets of shurry pump 2-1 and shurry pump 2-1 imports connection
2-2, slip extraction tube 2-3 and slip playpipe 2-2 extend into bottom in tower body 1；Agitating device is included positioned at 1 bottom of tower body
Four agitators 3, four agitators 3 circumference array centered on 1 axis of tower body, agitator 3 are included outside tower body 1
Motor 3-1 and the stirring vane 3-2 inside tower body 1, motor 3-1 are connected with stirring vane 3-2.
Slurry in tower body 1 is extracted by injection apparatus 2, is then sprayed again；Agitating device is stirred to slurry, is therefore sprayed
Device and agitating device are stirred can the serosity at absorbing tower bottom, prevent serosity from precipitating, so as to avoid absorbing tower
Bear building-up dirt." four agitators 3 circumference array centered on 1 axis of tower body " can be to carrying out multiple spot stirring in tower body 1, it is to avoid locally
The local scaling that stirring is not enough caused.Multiple ejiction opening 2-4 equally can be set on slip playpipe 2-2, it is also possible to avoided
The local scaling that not enough cause locally is stirred.
As shown in figure 1, remaining structure of flue gas desulfurization absorption equipment and fume desulfurating absorption tower is consistent with prior art, have
Lime white input pipe 4, lime slurry pump 5, oxygen input tube 6, oxygen pump 7, spray pump 8, spray slurry pipe 9 and spray thrower 10.
