Description
Technical field
The utility model is related to a kind of fiery grading plants that disappears that gathers dust of cement produced with the dry method rotary kiln grate-cooler, belong to flue dust collecting and set
Standby technical field.
Background technology
Raw material are in precalcining system after predecomposition at present, into rotary kiln in mature calcined material, sinter leaching heat consumption compared with
It is high（~3136kJ/kg.cl）.In order to reach good calcination operation and ensure the stabilization of clinker quality, enter cooling from rotary kiln
The high temperature chamotte of machine is cooled down by the cold air blasted under grate plate, and the clinker temperature for going out grate-cooler is+65 DEG C of environment temperature, is cooled down
Broken clinker is sent into clinker warehouse by bucket chain conveyor.
A cooler high-temp waste gas part is as kiln auxiliary air；Another part is sent to dore furnace conduct by tertiary-air pipe
Combustion air；Some exhaust gas is sent to coal mill, the drying heat source as pulverized coal preparation again；Remainder of exhaust gas gathers dust through bag collector
Afterwards, it is discharged into air.The dust that bag collector is accepted, which is sent to through chain transport machine on clinker chain bucket machine, enters clinker warehouse.
Since the long bag low pressure dust collection device of grate-cooler kiln hood is for cement clinker production line technology innovation project kiln hood clinker
The special dust collection device of feature special designing；It reasonably meet the dust settling time it is short, air inlet flue gas easily directly damage filter
Bag, ash cellar dust accumulation have been built excellent turbid room air-flow environment, have made dust-precipitator property indices by drawbacks such as turbid dirt interferences in air flow
The particular/special requirement of the industry smoke gas treatment of high temperature and dust is reached；Every monitoring index is better than national performance assessment criteria, in same
Industry-leading is horizontal.
When material dust is by gathering dust pipe network after air inlet enters dust-precipitator, initially strikes and press inclined clapboard, air-flow is at this
Ratio enters each filter chamber, while air velocity slows down as required under the effect of pressure inclined clapboard, and dust enters middle part filter chamber.Due to used
The effect of property, makes the bonding crude particle dust in flue gas directly be blown into ash bucket, plays the role of pre- gather dust.Remaining dust then rolls over body
It is uniformly slowly into upwards in the internal filter chamber equipped with the seamless metal cage bone of anti-corrosion, exhaust gas dust is trapped in the outer of cloth bag
Surface, purified gas enter the clean chamber interior on dust-precipitator top, are pooled to air outlet discharge.
Current dust-precipitator housing is divided into several independent filter chambers of gathering dust respectively using compartment plate, during deashing, PLC works
Industry control computer presses the entire deashing process of procedure auto-control：Pulse valve is opened and closed at timed intervals, cuts off the room filtered airflow,
PLC control by time variable jetting deashing pulse unlatching, by put on each filter bag injection nozzle by the dust adsorbed on filter bag be blown
Into ash bucket.Dust-precipitator uses chamber structure, and each turbid room independently works online by control program, and nothing mutually unloads clearly grey interference, it is ensured that
Effective sedimentation of lightweight micro mist, prevents dust from directly damaging filter bag.But processing high concentration high-temperature material can cause deduster system
Resistance of uniting rises, and cloth bag is easily burnt using shorter and cloth bag causes deduster to be not normally functioning.
Invention content
To solve the above problems, the utility model provides a kind of fire classification dress that disappears that gathers dust of cement produced with the dry method rotary kiln grate-cooler
It puts, gathers dust specifically for building material industry dry-process rotary kilns clinker production high-temperature technology, the special device of classified utilization pretreatment,
It is the technique flue dust point of a kind of combustion high temperature used suitable for the building material industries such as clinker, high concentration, extremely broad particle diameter distribution
Grade enrichment collection device.
The utility model is achieved by the following technical programs：A kind of fire point that disappears that gathers dust of cement produced with the dry method rotary kiln grate-cooler
Stage arrangement including frame, is separately positioned on two groups of Bag filter rooms of frame both sides and is arranged below Bag filter room
Two groups of powder buckets, it is characterised in that：Expansion chamber is set as between two groups of Bag filter rooms, expansion chamber bottom is equipped with one group of particle
Bucket, each Bag filter room, which is located on the siding of expansion chamber side, opens up air stream outlet, each Bag filter room
Top is set there are one clean room, and top of settling chamber is set as exhaust passage, and the side wall of each clean room is equipped with exhaust and divides hole, realizes and row
Gas channel connects.
The end of the expansion chamber is equipped with entrance.
The end of the exhaust passage is equipped with gas vent.
The Bag filter room is several one group of compositions of embarking on journey side by side.
The particle bucket is several one group of compositions of embarking on journey side by side.
The powder bucket is several one group of compositions of embarking on journey side by side.
The gathering dust of the utility model disappear fiery grading plant work when, directly handle the high temperature chamotte that rotary kiln enters grate-cooler
Cooling exhaust gas is forced, high-temperature material after entrance enters expansion chamber, makes most crude particle high temperature substrate with air-flow due to space is big
Material settles in expansion chamber and enters particle bucket, and small part dust enters multiple Bag filter rooms with air-flow through multiple air stream outlets
In, air-flow enters clean room, then enter exhaust passage through being vented a point hole across cloth bag, is most emptied afterwards through gas vent, and particulate dust
It is then attached on cloth bag, is collected in the powder bucket of the particulate dust on periodic cleaning cloth bag to bottom.
The advantages of the utility model has：For combustion high temperature, high concentration, extremely broad particle diameter distribution technique flue dust, profit
With conventional bagroom duct space, increase duct space air-flow, which remains in a standstill, expands chamber, and the dust of grain size >=30 μm is prevented to enter cloth
Bag filter chamber, while also greatly reduce powder and the mill of filter material surface is chiseled.It can well adapt to the red material maloperation of grate cooler
When paroxysmal high temperature, high concentration burning particles dust extreme operating condition gas cleaning filtering, timely and effectively solving cloth bag
While the hidden danger that scaling loss, mill are chiseled, realize that the fiery, classification that disappears, the purification filtering integration of kiln hood grate cooler cooling exhaust gas and dust are steady
Fixed operation；Independent particle storehouse and filler bin and its corresponding are respectively enterd after particle high-temperature hardness clinker and the classification of dust clinker
The particular/special requirement of transport system, it is ensured that the dust-precipitator filter bag steady operation service life is more than 5 years.
The utility model can be according to production technology difference（Temperature, concentration）In the case of oxygen content amount carry out flexible modulation.
The advantages that device structure is simple, easy to maintain, function-stable, preferable treatment effect, has saved floor space and investment；Pulse is sprayed
It is low to blow operating pressure（0.15—0.40MPa）Air consumption is small, energy saving, extends life-span of the filter bag；Processing dust content height and
During the big flue gas of water capacity, good deashing is still kept.Building material industry raising resource circulation utilization rate, raising life now can be used as
Force of labor avoids the destructive important device of equipment.
