Description
Technical field
The utility model relates to a kind of reaction tower tower bottom automatic removing dusts to crush Pneumatic conveyer.Applied to recirculating fluidized bed
Dry desulfurization denitration field.
Background technique
Flue gas circulating fluidized bed dry desulfurization denitration technology is a kind of low-temperature flue gas desulfurizing and denitrifying process.The technique has
It is excellent that denitrification efficiency is high, investment operating cost is low, high reliablity, occupied area is small, generate without waste water, by-product is easy to handle etc.
Point.The technology has tended to be mature and has had the irreplaceable advantage of other techniques, and the market demand gradually expands.
The key reaction place of circulating fluidized bed dry desulphurization denitration is reaction tower.Flue gas enters tower by lower inlet section
It is interior, by entering tower body principal piece after the expansion of tower lower part and cloth wind section, and mixed with the absorbent of addition and technique atomized water, after
Continuous reaction, finally flows out from tower upper outlet section.Subsequent flue gas enters bag filter, the Desulphurization trapped through deduster
It is sent back in tower through air flume and continues to participate in reaction.
At present during dry flue gas desulphurization, it is very universal that absorbing tower bottom falls ash, especially bulky grain in absorption tower
The phenomenon that falling on tower bottom is than more serious, in addition, flue gas circulating fluidized bed it may also happen that an accident of collapsing, causes ash in tower a large amount of
It is piled up in stack base.Usually processing is directly transported by ash discharge landing or by vehicle by tower bottom ash discharging hole.Ash discharge
Landing can all cause a large amount of fugitive dusts with the process that vehicle is transported, and increase the workload of operation and maintenance personnel.
Dry desulfurization denitration absorbing tower bottom ash ejector generallys use single axle helical ash ejector.When tower bottom ash quantity is too big, or
After person's tower bottom ash is hardened, starting single axle helical ash ejector is just likely to cause motor tripping.To not arrange ash.Deal with difficulty
It spends very big.
In dry desulfurization denitrating system During Process of Long-term Operation, the spray gun pipette tips in tower are likely to occur blocking and cause atomized water spray
Change the bad situation of effect, taking guttiferous ash constantly reunion balling even can occur agglomerating and falling on tower bottom.At this moment tower bottom is arranged
Ash out directly carries out pneumatic conveying and is bound to cause equipment or line clogging because having balling or grey block.Therefore tower bottom ash is not
Pneumatic conveying can directly be carried out.
Utility model content
The purpose of this utility model is that in view of the above problems, a kind of mitigation operation personnel's workload is provided,
Realize that automatic removing dust crushes the device of simultaneously pneumatic conveying, solving tower bottom ash ejector may be because that ash is hardened and causes ash discharge electromechanical
The problem of machine trips, pneumatic conveying cannot directly be carried out by solving tower bottom ash, thus caused by needing in landing and transport process
Fugitive dust problem.To enhance the reliability of entire desulphurization denitration dust pelletizing system stable operation.

On the pump discharge pipeline of storehouse, for monitoring the pressure on the pump discharge pipeline of storehouse.
It wherein, further include control device, during entire defeated ash, the reaction tower tower bottom ash discharge crushes Pneumatic conveyer
Automation control is realized by control device.
Wherein, band multi-disc hobboing cutter on arbor is crushed, impact comminution is carried out to blocky powder of reuniting by high speed rotation；Hobboing cutter
Lower section has sieve, and grinding particle size is controlled by replacing different pore size sieve.
A kind of reaction tower tower bottom automatic removing dust crushing Pneumatic conveyer is also provided, tower bottom air channel structure includes cone bucket section,
And be that level-sensing device is arranged in cone bucket, twin shaft ash ejector is arranged in cone bucket dust inlet.When level-sensing device has been sensed and fallen in tower bottom cone bucket
When grey, ash ejector starting, by the ash fallen first pass through lower section pulverizer will agglomerate or balling fall ash and crush, enter back into storehouse
In pump, laggard promoting the circulation of qi power is filled to storehouse pump and is transported to grey library.Whole process realizes automation control.
The twin shaft ash ejector is dispersed with multi-disc sector stirring blade, double-axis reverse with certain helical angle and screw pitch on axis
Rotation material is stirred, helical feed.Since twin shaft ash ejector is discontinuous compared to single axle helical ash ejector blade, it is not easy to
Because hawk is carried down motionless problem between blade and shell, and has certain stirring fragmentation, ashing capacity is greatly reinforced.
The pulverizer.Blocky powder of reuniting is rushed its working principle is that crushing multi-disc hobboing cutter high speed rotation on arbor
Hit crushing.Sieve is had below pulverizer hobboing cutter, grinding particle size is controlled by replacing sieve, and sieve is replaceable.
The utility model has the following beneficial effects: the utility model is by setting gradually twin shaft ash ejector, powder at reaction tower bottom
Broken machine, pneumatic delivery bin pump complete set of equipments efficiently avoid the stuck problem of tower bottom ash ejector；And it is set by increasing pulverizer
Standby, pneumatic conveying cannot directly be carried out by solving tower bottom ash, to avoid fugitive dust problem caused by ash landing and transport process.
Design rationally, reduces the workload of tower bottom ash discharge processing, enhances the reliability of system stable operation.
