Description
Technical field the utility model relates to a kind of corollary equipment of boiler.
Therefore background technology has been widely used in every field because CFBB has premium properties such as high-efficiency low-pollution.But higher from the ash temperature that CFBB is discharged, generally at 800～900 ℃, so red-hot lime-ash has not only worsened the field operation condition, and has taken away a large amount of heat energy; Residual sulphur and nitrogen still discharges sulfur dioxide and nitrogen vapour in the lime-ash outside stove simultaneously, causes environmental pollution.People successively design the multiple slag cooler supporting with it for this reason, carry slag cooler, moving-bed type slag cooler, oscillatory type slag cooler and cagem type slag cooler etc. as tubular type slag cooler, sulfuration bed economizer, cartridge type slag cooler, strength.Wherein combustion property is little again, processing bulk ability is strong, heat recovery rate is high, so performance is better than other slag cooler owing to the lime-ash of not blowing for the cagem type slag cooler.The structure of this cagem type slag cooler is basically: on the housing that slag notch is arranged under the slag input hopper is arranged is inside and outside two-layer, establish the intake-outlet that is connected with interlayer on it respectively, level runs through the hollow shaft of housing two end cover plate, its part surface that is positioned at housing is provided with helical blade, and the part that hollow shaft is positioned at housing outside is established intake-outlet and linked to each other with driving mechanism.Its weak point is: lime-ash only carries out heat exchange with housing and hollow shaft surface, and heat transfer efficiency is low, do not reach required cooling effect.
The summary of the invention the purpose of this utility model is to provide that a kind of film-cooled heat is big, the spiral slag cooler of good cooling results.The utility model mainly is that blade is designed to bilayer, makes the water jacket that its interlayer becomes flow of cooling water.Housing of the present utility model and prior art are basic identical, are the inside and outside two-layer housing that slag notch is arranged under the slag input hopper, establish the intake-outlet that is connected with interlayer on it respectively.Establish the deflector that increases the cooling water stroke in the crustless sandwich for making the cooling water in the interlayer fully carry out heat exchange, being preferably in lime-ash.Be positioned at the outer driving mechanism of housing and link to each other with rotary body, this rotary body mainly includes: power shaft, mandrel, blade, output shaft, oral siphon.Wherein the power shaft other end that links to each other with driving mechanism of an end passes the discharge end cover plate and is inserted in the tubular mandrel and with it and fixedlys connected both clearance seals.This is located at the mandrel in the housing, and its outer surface is provided with helical blade, and this blade is double-deck.The other end of mandrel is fixed on the output shaft outer surface by the annular connector of correspondence, both gap sealings.The end that this tubulose output shaft is inserted in the mandrel also is fixed in the mandrel by the annular connector of correspondence, both gap sealings.On the output axial wall between the two annular connectors, be provided with through hole, and on the mandrel between this two circular connector, also be provided with through hole, and this through hole is connected with the blade interlayer, and it is the blade apopore, the blade inlet opening is located near on the mandrel wall of power shaft, and is connected with the blade interlayer.Above-mentioned output shaft passes feeding end cover plate end top and is positioned at outside the housing, can join with drainpipe.Be provided with oral siphon in the output shaft, its external diameter is less than the output shaft internal diameter, and making has certain interval between the two.This oral siphon one end is located at output shaft and is positioned on the hole of mandrel inner end, and is connected with the mandrel chamber, and the other end is positioned at outside the housing and can links to each other with pumping line.Best above-mentioned output shaft and interior oral siphon thereof are positioned at the outer end of housing and link to each other with swivel joint.This swivel joint mainly is made up of pivoted housing, fittings body, support ring, water inlet gland and seal.The pivoted housing that is connected with output shaft of an end wherein, the other end of establishing through hole on its wall is inserted in the fittings body, and by being located at annular support ring on this circular groove shape fittings body opening with its activity orientation and sealing.Outside the fittings body opening, be provided with mechanism with support ring location and sealing.Partly be provided with the adapter that links to each other with drainpipe at the fittings body circular groove.The fittings body top links to each other by the flange of securing member with the water inlet gland, and the straight tube of flange one side is inserted in the central through hole at fittings body top, establishes sealing ring between the two.Above-mentioned oral siphon is positioned at the outer end of housing and then is inserted in this straight tube.The flange other end is established the bend pipe that can connect with pumping line.
The utility model course of work is as follows: driving mechanism by power shaft drive mandrel and on blade rotation, mandrel orders about coupled output shaft again and rotates, and the also rotation thereupon of the pivoted housing of the swivel joint that links to each other with output shaft.The result that above-mentioned each parts rotate just will be pushed into slag notch and discharge from the lime-ash that the slag input hopper enters in the housing.Above-mentioned lime-ash is cooled again when moving, and the approach of its cooling has two, and the first contacts with housing by cooling water temperature; It two is to contact with rotary body by cooling water temperature.The cooling water of this rotary body is to enter in the oral siphon from swivel joint water inlet gland, and enters mandrel from the end that output shaft is positioned at mandrel, again from entering in the interlayer of helical blade near the through hole on the mandrel wall of power shaft.Rotation along with blade, cooling water flows to high temperature section from low-temperature zone, and flow out from high temperature section mandrel through hole, again in the output shaft through hole enters the interlayer that itself and water pipe form, after cooling water enters swivel joint, enter again in the interlayer of pivoted housing and water pipe, the through hole through the pivoted housing end flows out again, is discharged by the adapter on the fittings body.
The utility model advantage specific as follows compared to existing technology:
1. simple in structure, easy to operate, volume is little, easy installation.
2. shell, blade and rotating shaft all can be cooled off lime-ash, have increased heat transfer area, and cooling effect is improved greatly, have reduced tapping temperature.
3. stable, adaptability is strong, long service life.
4. complete machine sealing, high-temperature ash be ingress of air, the coking of prevention slag secondary not.
