Description
Technical field
The present invention relates to technical field of environment protection equipment, and in particular to a kind of fluidized dryer compound type dust remover and its control
System processed.
Background technique
With the improvement of the quality of life, requirement of the public to air quality is also higher and higher, however in all trades and professions industry
In the case where change, the industries such as metallurgy, building materials, chemical industry can all generate a large amount of dust every year, to human health, air quality and life
State environment all causes serious influence.The especially dust of pharmaceutical chemical industry industry generation is very big to human health damage.
Fluidized dryer is used for pharmaceutical industry, and dust particles have certain pharmacological property, therefore cannot use wet scrubber；
Its contained dust size range is big, it is desirable that dust pelletizing system has a good separation property ability to minute dusts, and common dedusting
Equipment separative efficiency is poor, does not reach requirement；And air quantity fluctuation is larger when machine production, therefore it is required that dust pelletizing system resists wind
The ability for measuring fluctuation is stronger.
Traditional fluidized dryer is often mostly sack cleaner and cyclone dust collectors with deduster.
Cyclone dust collectors are to remove dust particles from dust-contained airflow using centrifugal force, and this deduster structure is simple, makes
Valence is cheap, the operation is stable, but poor to the dust elimination effect of 10 μm or less partial sizes；Leakproofness is affected to it simultaneously, has
Statistics indicate that when cyclone dust collectors leak out 10 ~ 15% when efficiency of dust collection will be for 0.
Sack cleaner is a kind of deduster widely used at present, its working principle is that using materials systems such as glass fibres
At filter bag, utilize the sieving effect of fabric, inertial collision effect and diffusion etc. to realize gas solid separation.However, working as
When the treating capacity of dust is larger, the dust particles accumulation adhered on filter bag is excessive, and the pressure difference and resistance of filter bag two sides increase.When
When the pressure of filtrate two sides reaches certain value, then the little particle dust being attached on filtrate, which may be squeezed, to roll over
It is discharged into atmosphere, substantially reduces efficiency of dust collection, and reduces the service life of filter bag.Even if having one during deduster operation
Cloth bag rupture, all may cause ash discharge concentration and increases rapidly, and air-flow also results in the filter bag by the broken hole of very little on filter bag
And the rapid damage of the neighbouring filter bag of surrounding, set off an explosion or even cause catastrophic loss.
Summary of the invention

The strainer 26 by 8 bottom of inner conical-tube is moved upwards, dust particles generate used under the action of strainer 26 is stopped with gravity
Property sedimentation, realize third level dedusting；Dust-contained airflow continues to ascend into filter bag dedusting area, filter bag 10 sieving, intercept, touch
Hit, spread and electrostatic attraction under the action of, fine dust particles are attached to 10 surface of filter bag, then by pulse jetting deashing device
11 are cleaned to the dust particles being attached on filter bag 10 in dust bucket 23, complete fourth stage dedusting, and last clean gas flow is from cylinder
Body gas outlet 16 is discharged, and is discharged into atmosphere along exhaust pipe 17 under the action of air-introduced machine 24.
In the present embodiment, dust-contained airflow passes through powerful centrifugal force and diversion pipe 4 in gas gyro dedusting area and cyclone dust removal area
The blocking of 9 inner wall of tube wall and cylinder and gravity, can efficiently separate 10 μm or more of large dust particle, and make from fluidized drying
The high temperature dust air-flow cooling of machine outflow, to reduce workload and large dust particle the washing away to filter bag 10 of filter bag 10
Effect, the effective service life for extending cleaning cycle and filter bag 10.Cyclone dust collector is mounted at cylinder air inlet, and interior
Cone presentation is horn-like, and when air-flow passes through cyclone separator, air-flow will become circular motion from linear motion.Swirling eddy
The overwhelming majority is twist downward from cylinder along wall, flows towards cone.Usually it is referred to as outer rotational gas flow.Dusty gas is revolving
Centrifugal force is generated during turning, and the grit that severe is greater than gas is got rid of to wall.Grit is once contacted with wall, just loses inertia
Power and by entrance velocity momentum and downward gravity along wall surface fall, into ash releasing tube.The outer rotational gas flow of rotation decline arrives
When up to cone, drawn close due to the contraction of cone to deduster center, tangential velocity is continuously improved.When air-flow reaches under cone
When holding a certain position, i.e., with same direction of rotation in the middle part of the cyclone dust collectors, by lower reversion on, continue to make spiral current
It moves, i.e. interior rotational airflow.Cyclone separator provides lifting power to air-flow, carries out effective temperature-reducing to high-temperature gas, enters back into inner cone
When body, due to the shape that inner cone is up big and down small, good buffer function can be played, thus is formed at cyclone inlet
Air pressure is high, and inner cone air pressure inside is low, before gas enters filter bag dust-extraction unit, further cools down.Gas flow temperature reduce to
The damage for reducing filter bag, to improve the security performance of device.
In the present embodiment, measurement detects bag-type dusting area and dust bucket 23 respectively for bag side thermometer 19 and grey side thermometer 20
The temperature in area prevents the excessively high damage for making dust spontaneous combustion and high temperature to filter bag 10 of gas flow temperature；Once control system detects super
Temperature, PLC system 21 open electromagnetic impulse valve 11 by sending control signal, the pressure in the pressure stabilizing gas bag of pulse spraying equipment 12
Contracting air sprays to filter bag 10, while can cooling down but also the long-pending dust releasing for being attached to 10 surface of filter bag is made to reach ash-removal effect.
In the present embodiment, deashing device is equipped with above exhaust dust device with bag, deashing device includes Venturi tube 14, pulse
Blowing device 12 and electromagnetic impulse valve 11, wherein pulse spraying equipment 12 is provided with corresponding 10 numbers of filter bag in the top of filter bag 10
Several injection tubes and nozzle, when needing to carry out deashing processing, PLC control system 21 sends a signal to electromagnetic impulse valve 11
Open valve, the compressed air in the pressure stabilizing gas bag of pulse spraying equipment 12 enters injection tube, and sprays to filter bag 10 by spray orifice
Sack, each sack is equipped with an oviduct, when thus high-speed compressed air flows through, generates certain negative pressure, keeps sack attached
Close clean gas causes filter bag 10 sharply outside expansion and impact vibration, so that product be made to be attached to filter bag with filter bag 10 is entered
The dust releasing on 10 surfaces.
In the present embodiment, differential pressure measuring system 18 detects 10 inside and outside differential pressure of filter bag, when detecting that pressure difference reaches presetting
When value, PLC system control sends signal and electromagnetic impulse valve 11 is opened progress deashing, will be attached to the dust on 10 surface of filter bag
Grain is removed, and reaching reduces pressure difference and deashing double effects.
