Abstract
The utility model discloses an air-cooled type cyclone dust collector. The cyclone dust collector is adopted as a main body and comprises a barrel body, a conical body, a gas inlet, a gas outlet and a dust outlet pipe; high-temperature dusty gas enters in the barrel body in the tangent line direction of the barrel body through the gas inlet; dust enters in the conical body after being separated from the gas due to a centrifugal force and is discharged through the dust outlet pipe; an air-cooled jacket is sleeved outside the barrel body of the cyclone dust collector and comprises a sleeve, an air inlet and an air outlet; a barrel body of a cyclone separator is totally or partially wrapped with the sleeve; and the air inlet and the air outlet are respectively arranged at the lower part and the upper part of the jacket. Compared with a structure that the air-cooled jacket is placed in the cyclone separator, the contact area is increased, the heat exchange effect is enhanced, and molten or semi-molten metal liquid drops (vapors) carried in the high-temperature gas are favorably removed.
Description
Technical field
The utility model relates to a kind of air-cooled deduster, belongs to energy-saving dedusting equipment.
Background technology
Cyclone dust collectors are made up of cylindrical shell, cone, air inlet, gas outlet etc., and dusty gas gets into cyclone dust collectors by air inlet, rotates in deduster inside.Dust granule separates from air-flow under centrifugal action, and speed reduces, and combines in gradually on the deduster inwall, under the gravity effect, discharges from the deduster bottom then.Cyclone dust collectors are because it is simple in structure, and advantages such as good dedusting effect are widely used in the dedusting of dusty gas.
But, can run into some problems with common cyclone dust collectors in the high-temperature flue gas of processes such as industry heating or melting dischargings (or other high-temperature gases, down with).Problem one: because the heat transfer of cyclone dust collectors inwall is good, after high-temperature flue-gas reach a certain height, the material of inwall just must be selected high temperature resistant material for use, perhaps increased thermal insulation layer, can increase cost like this.Problem two: the molten drop (steam) that often carries fusion or semi-molten state in the high-temperature flue gas.Such as the molten aluminium stove of using in a large number in the die casting industry; The aluminium drop (steam) that in molten aluminium process, contains a large amount of fusions or semi-molten state in the discharged flue gas; Because drop or " steam " are very small, after mixing with high-temperature gas, be difficult to removed by common cyclone separator.
Along with the propelling of national energy-saving and emission-reduction policy, the heat that carries in the high-temperature flue gas that smelting furnace is discharged is by progressively recycling.And in recycling the process of this part heat, after these small molten drops (steam) are cooled, can condense gradually and attached on the waste heat recovery apparatus, have a strong impact on the efficient of waste heat recovery apparatus and the safe operation of equipment.Therefore the Problems of dust that solves this part high-temperature gas becomes very urgent.
Summary of the invention
The utility model can't be removed the fusion of carrying in the high-temperature gas or the molten drop problems such as (steam) of semi-molten state to existing deduster, provides a kind of and makes this part drop (steam) cool off, solidify and separated the air-cooled cyclone dust collectors of removing by deduster.
The technical scheme of the utility model is following:
A kind of air-cooled cyclone dust collectors, its main body is cyclone dust collectors, cyclone dust collectors are made up of cylindrical shell, cone, air inlet, gas outlet and ash releasing tube; High temperature dust gas gets into along the cylindrical shell tangential direction through air inlet, and dust gets into cone because centrifugal force separates the back from gas, discharges through ash releasing tube.
Outside the cylindrical shell of cyclone dust collectors, be with air-cooled chuck, said air-cooled chuck is made up of sleeve, air inlet and air outlet; Sleeve is with all or part of parcel of the cylindrical shell of cyclone separator, and air inlet and air outlet lay respectively at chuck bottom and top.This structure structure inner with air-cooled chuck being placed cyclone separator compared, and this structure has increased contact area, has strengthened the heat exchange effect.
Simultaneously the water conservancy diversion and the disturbing flow device of flow deflector, guiding gutter or turbolator form are installed in air-cooled chuck, can be made the high-temperature flue gas in the abundant cooling and dedusting device of cold wind, make the cylindrical shell wall be in low-temperature condition.
The air-cooled deduster of the utility model is compared with existing equipment and is mainly contained following advantage:
1) through increasing air-cooled chuck, realized the function of dedusting and heat exchange simultaneously; Be particularly conducive to and remove the fusion of carrying in the high-temperature gas or the molten drop (steam) of semi-molten state.
2) increase cooling provision, strengthened dust removing effects;
3) because cooling effect has reduced the requirement of cyclone separator cylindrical shell material, increased service life of equipment;
4) simple in structure, easy to operate.
Description of drawings

Fig. 2 is the vertical view of the utility model
Among the figure, gas outlet 1, air outlet 2, sleeve 3, air inlet 4, ash releasing tube 5, cone 6, cylindrical shell 7, air inlet 8, air-cooled chuck 9, cyclone dust collectors 10.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises cyclone dust collectors 10) and air-cooled chuck 9.
Air-cooled chuck 9 is made up of sleeve 3, air inlet 8 and air outlet 2; Sleeve 3 is with the cylindrical shell 7 all or part of parcels of cyclone separator 10, and air inlet 8 lays respectively at lower cartridge and top with air outlet 2.
The high-temperature flue gas of the aluminium drop (steam) that contains a large amount of fusions or semi-molten state that produces in the molten aluminium stove is through air inlet 1 is got into the cylindrical shell 7 of the cyclone dust collectors in the air-cooled deduster by tangential direction in, and cold wind is got in the air-cooled chuck by air inlet 8 simultaneously.Carry out sufficient heat exchange through water conservancy diversion and disturbing flow device by cold wind and cyclone dust collectors wall, make that the cylindrical shell 7 interior high-temperature flue gas of cyclone dust collectors 10 are cooled off gradually, the aluminium drop (steam) of fusion or semi-molten state is condensed into solid granular gradually.Because action of centrifugal force, this part metallic particles separates with high-temperature flue gas, and is discharged by ash releasing tube 5 through the cone 6 of cyclone dust collectors 10.Cold wind and high-temperature flue gas are done in the same way or reverse rotatablely moving with cyclone dust collectors 10 at air-cooled chuck 9 respectively, and fully after the heat exchange, the high-temperature flue gas that is cooled is discharged by gas outlet 1, is discharged by air outlet 2 by the hot blast of flue gas heating.
