Embodiment：
Accompanying drawing 1 is the main structure diagram of multi-cyclone dedusting cooler, and dedusting cooler is installed on support and platform 1
On, ash bucket 2 is arranged at bottom, and satisfaction unloads the working space requirement such as grey entrucking or maintenance.It is furnished with unloading valve 7 in 2 times mouths of ash bucket, periodically row
Go out internal collection ash.The top of ash bucket 2 is shell side bellows 3, and shell side bellows 3 have two interfaces, and one is air inlet, positioned at shell side bellows
3 side, there is provided four axial flow blowers 6, one is hot-blast outlet, positioned at the opposite side of shell side bellows 3, connects High-temp. kiln
Hot wind inlet.Multiple cyclones 5 are installed, the riser 8 of cyclone 5 stretches into entering for the top of shell side bellows 3 in shell side bellows 3
In outlet bellows 4, shell side bellows 3 are separated with entering outlet bellows 4 using upper perforated plate 19.Entering outlet bellows 4 has two interfaces, one
It is high-temperature flue gas import, one is to cool the exhanst gas outlet of pre- dedusting, connects sack cleaner.As shown in Figure 2, multiple cyclones
5 are arranged on the upper perforated plate 19 of shell side bellows 3 with equilateral triangle.The quantity of cyclone 5 and dedusting air quantity, high-temperature flue gas dustiness and
Heat exchange area is relevant, is the core of dedusting cooler design, and this example cyclone 5 amounts to 23.
The main function components of this multi-cyclone dedusting cooler are cyclones 5, as shown in Figure 3, each cyclone 5 by
Riser 8, swirl vane 9, the 11 groups of welderings of housing 10 and wind deflector are formed.The top of housing 10 is straight tube shape, and bottom is taper.Rotation
Stream blade 9 is welded on riser 8, is the petal axial screw plate shape formula of multiple-piece as shown in Figure 6.Due to high-speed and high-temperature
Flue gas from swirl vane 9 by and change flow direction, the dust in flue gas, which produces larger high speed to swirl vane 9 and washed away, to rub
Wipe, to improve the service life of swirl vane 9, swirl vane is made using high-abrasive material or using the processing of surface overlaying wearing layer
Technique makes.Wind deflector 11 is axial baffle, prevent caused by the bottom of housing 10 is because of cone small end cross-sectional area increase and
Cold wind short circuit is produced, makes cold wind and the abundant contact heat-exchanging of housing 10, heat exchange efficiency is improved.
When multi-cyclone dedusting cooler works, high-temperature flue gas pumps the cigarette of outlet bellows 4 by system air-introduced machine
Gas import simultaneously enters cyclone 5 and carries out rotational flow dust-removing high-temperature flue gas and produce Whirl deposite tank in the presence of swirl vane 9, and along
The inwall of housing 10 is moved downward, and is reached behind housing 10 bottom, by the water conservancy diversion of conical shell, and turnover is upward, into riser 8, and edge
Riser 8 enters outlet bellows 4, is discharged by air outlet, and further purified treatment is carried out into follow-up bag-type dusting.
Acted in high-temperature flue gas in housing 10 by eddy flow centrifugal force field and gravitational field, larger dust in flue gas
Grain by centrifugal action, got rid of to the inwall of housing 10, with interior wall friction and lose kinetic energy, so as to be captured, under gravity
Ash bucket 2 is fallen into, pre- dedusting purpose is reached.Meanwhile, high-temperature flue gas and the outside pressure produced by axial flow blower 6 in housing 10
Cold wind carries out heat exchange by housing wall, so as to reach cooling purpose.
As shown in Figure 3, the housing 10 and riser 8 of each cyclone 5 are installed using single-ended fixed floating assembly, with
It is adapted to the expanded by heating at work of cyclone 5, it is to avoid because the stress that thermal expansion is produced causes tube plate deformation.The upper end of housing 10 and shell
The upper perforated plate 19 of journey bellows 3 is fixedly connected.Filled between the lower perforated plate 18 of its lower end and shell side bellows 3 using stuffing-box floating connection
Match somebody with somebody.As shown in Figure 4, packing filling 12 is equipped between the lower perforated plate 18 of the lower end of housing 10 and shell side bellows 3 and with gland 13
Compressed with screw 14.
As shown in Figure 5, the top of riser 8 and enter between the demarcation strip 17 in outlet bellows 4 is floated using stuffing-box
It is linked and packed, packing filling 15 is equipped between demarcation strip 17 and is compressed with pressing plate 16.As shown in Figure 7, the lower end of riser 8
Insert housing 10 and rely on the flange support of swirl vane 9 in the air inlet end face of housing 10.
Present apparatus set cyclone dust removal efficiency and sky-sky cooler efficiency, reduce by 50~80 DEG C of flue-gas temperature, meet
The operating temperature of follow-up bag-type dusting filter bag（Maximum operating temperature is below 200 DEG C）It is required that, while flue gas can be trapped effectively
In be more than 50 microns of dust, reduce the live load of follow-up bag-type dusting.The present apparatus protects bag-type dusting filter bag from height
Temperature destruction and the abrasion of big particle diameter dust, extend service life.
This multi-cyclone dedusting cooler construction is simple, reliable operation, and pre- efficiency of dust collection is high, and cooling-down effect is obvious, very
It is suitable for high-temperature flue gas bag-type dusting and carries out the pre- dedusting of cooling before purified treatment.It is combustion-supporting in hot blast feeding stove after heat exchange,
The recycling of heat is accomplished.
