Abstract
The utility model discloses a pulsed bag type deduster for uniformly distributing air flow. The pulsed bag type deduster comprises a box body, a dust hopper with a dust discharge valve, a filtering chamber and an air cleaning chamber, wherein a dust hopper frame is arranged outside the dust hopper; an air duct tilting partition plate is arranged in the filtering chamber, and an air inlet and an air outlet are respectively arranged on both sides of the filtering chamber; a pulsed dust cleaning device is arranged above the air cleaning chamber, a porous place used for installing a filter bag is arranged between the filtering chamber and the air cleaning chamber, and a pre-dedusting device is arranged at the air inlet of the deduster; a flow baffle plate is arranged above the air duct tilting partition plate; and a gap a is arranged between the bottom of the filter bag and the dust hopper frame.
Description
Technical field
The utility model relates to a kind of pulse bag type dust collector, particularly a kind of pulse bag type dust collector of airflow uniform distribution.
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.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/m3～1000g/m3, because dustiness is big, the dust deadweight is heavier; And wind speed generally is controlled at about 24m/s in the pipeline, so wind speed must be greater than the dust own wt in the pipeline, and directly with after cleaner is connected; Because too high, the unequal factor of air-flow of wind speed; Meeting wear equipment internal structure is damaged filter bag, causes deduster to work.
Summary of the invention
The utility model technical problem to be solved provides a kind of pulse bag type dust collector of airflow uniform distribution, can effectively reduce blast pipe wind speed, uniform air flow, guarantees deduster operation steady in a long-term.
The utility model technical scheme that adopts of dealing with problems is: a kind of pulse bag type dust collector of airflow uniform distribution; Comprise casing, have ash bucket, filter chamber, the air-purifying chamber of unloading valve; Said ash bucket is provided with the ash bucket frame outward; In said filter chamber, be provided with the air channel inclined clapboard, both sides, said filter chamber are respectively equipped with inlet and outlet, above said air-purifying chamber, are provided with pulse ash remover; Between filter chamber and air-purifying chamber, be provided with porous plate and be used to install filter bag, the place is provided with pre-dedusting device at said deduster air inlet; Said air channel inclined clapboard is provided with flow-stopping plate; Be provided with certain interval a between said filter bag bottom and the ash bucket frame.
As a kind of preferred, said pre-dedusting device is made up of support, body, blast pipe and discharge pipe.
During the utility model work; The dusty gas of wind speed about 24m/s done the sedimentation of one-level reduction of speed after pipeline gets into cleaner through pre-dedusting device in the pipe; Flow-stopping plate by being located on the inclined clapboard of air channel is made even wind-guiding, does last reduction of speed and current-sharing by the gap between filter bag bottom and ash bucket frame at last.
The beneficial effect of the utility model is: before cleaner, be provided with pre-dedusting device, can effectively reduce air-flow velocity and sedimentation than crude particle dust; On the inclined clapboard of equipment air channel, be provided with the flow-stopping plate of high-abrasive material; The direct flush equipment internal structure of the dusty gas of wind speed about 24m/s in can avoiding managing; It is consistent to make dusty gas airflow direction and filter bag ash removal shake off direction, has avoided dust to attach again, but not only dust-break but also evenly wind-guiding; When big particle is impacted, promptly loses inertia and fall to ash bucket; Space between casing lower end and ash bucket frame can effectively reduce air-flow velocity, thereby reduces the dust concentration of dusty gas by a relatively large margin the service life that can improve filter bag, improves efficiency of dust collection, guarantees deduster operation steady in a long-term.
