Abstract
The utility model discloses a dewing-preventing pulse bag type dust remover for copper smelting, which comprises a support frame, an ash bucket with cindervalves, a filter chamber and a purified gas chamber; a pulse ash removing device is arranged above the purified gas chamber; a filtering bag is arranged between the filter chamber and the purified gas chamber; the pulse bag type dust remover further comprises a dewing-preventing device arranged at the periphery of the filter chamber and the periphery of the ash bucket; the dewing-preventing device comprises a steam manifold, a steam pipe and a steam drain-pipe; heat-insulating rock wool and a heat-insulating corrugated color steel plate are arranged at the periphery of the steam pipe; a gate valve is arranged between the steam pipe and the steam drain-pipe; and a drain device is arranged at the inlet of the steam manifold, and comprises a stop valve and a drain valve. The utility model can effectively prevent the pulse bag type dust remover from dewing and ensure the long-term stable operation of the pulse bag type dust remover.
Description
Technical field
The utility model relates to a kind of pulse bag type dust collector, and particularly a kind of copper that is used for is smelted resistive connection dew pulse bag type dust collector.
Background technology
At present, it is from the pyrometallurgical smelting process, the flue dust in the ash-laden gas to be carried out Separation and Recovery that the copper flue gas during smelting gathers dust, and the process of gathering dust is the pollution control process, also is production process.Flue dust is important first resource, or even the important intermediate products of production process.Main gathering dust comprises that dry flue gas gathers dust, melting flue gas dust collection, the flue gas dust collection that blows, contains arsenic melting flue gas dust collection, electric dilution flue gas dust collection and refining flue gas dust collection.
Flash smelting is a kind of advanced person's of getting up of RECENT DEVELOPMENTS a smelting technique, and the flue gas water content that in flash smelting copper concentrate dry run, produces is big, and flue-gas temperature is 80 ℃～200 ℃, dust contained flue gas 20g/m
3～1000g/m
3Because flue-gas temperature height, water capacity and dustiness are bigger; In this technology, all adopt the two or 3-stage dust-removal: the one at present, rotoclone collector adds blowback wind sleeve deduster and adds heat-insulation layer again; The 2nd, increase heavy dirt chamber and rotoclone collector before the cottrell, these two kinds of complex process of gathering dust, cost of investment is big; Again because humidity of flue gas is big and the flue-gas temperature fluctuation is big; Dewfall still can take place in the sack cleaner that when flue-gas temperature is lower than dew-point temperature, only adds heat insulation layer structure, causes filter bag to stick with paste bag, causes deduster to work.
Summary of the invention
The utility model technical problem to be solved provides a kind of copper that is used for and smelts resistive connection dew pulse bag type dust collector, effectively prevents the sack cleaner dewfall, guarantees deduster operation steady in a long-term.
The utility model technical scheme that adopts of dealing with problems is: a kind of copper that is used for is smelted resistive connection and is revealed pulse bag type dust collector; Comprise bracing frame, have ash bucket, filter chamber, the air-purifying chamber of unloading valve; Said air-purifying chamber top is provided with pulse ash remover, is provided with filter bag between said filter chamber and the air-purifying chamber; Comprise that also resistive connection reveals device; Said resistive connection reveals the periphery that device is arranged at filter chamber and ash bucket; Said resistive connection reveals device and comprises main steam range, steam pipe, steam drainpipe, and said steam pipe periphery is provided with heat preservation rock and insulation corrugation color steel, is provided with gate valve between said steam pipe and the steam drainpipe; Said main steam range import department is provided with drainage arrangement, and said drainage arrangement comprises stop valve and drain valve.
During the utility model work, steam enters into each steam pipe from main steam range, is discharged by the steam drainpipe at last, and the water that condenses in the main steam range is discharged by the drain valve of drainage arrangement, prevents the leakage of steam simultaneously to greatest extent.
The beneficial effect of the utility model is: the periphery at filter chamber and ash bucket is provided with resistive connection dew device; When temperature is lower than dew-point temperature; Combine the insulation measure with steam-heated mode, can prevent effectively that sack cleaner from because of dewfall causes filter bag paste bag, guaranteeing dust pelletizing system operation steady in a long-term.Gate valve between steam pipe and the steam drainpipe can be closed when maintenance, does not influence the operation that whole sack cleaner resistive connection reveals device.
