Method dusty gas being filtered using above-mentioned gas-filtering device, is concretely comprised the following steps：
(1) dusty gas is passed through gas passage from dust-laden air inlet, is purified by grain bed from top to bottom, dust-laden
In gas, dust is piled up above grain bed, and gained purification gas are drawn from clean gas outlet；
(2) with the accumulation of dust, form dust filter membrane above grain bed, described dust filter membrane can improve dedusting effect
Really；Continuation with dust accumulation thickness increases, and the flow resistance of air increases, dusty gas flow reduces；
(3) when dust accumulation is blocked up, to defecator cannot normal work when, will be positioned at dust outlet by dedusting slide block
Dust above lower surface is pushed into dust collection area, makes the dust filter membrane thickness above grain bed thinning, thus reducing air
Flow resistance, increase dusty gas flow, recover defecator work；
(4) when dust accumulation highly switchs close to dust collection area in dust collection area, close dust collection area switch,
Open sealable dust outlet, dust is discharged dust collection area；Then turn off sealable dust outlet, open dust
Collecting region switchs；In the process, defecator need not be shut down, and proceeds gas filtration, continuous work.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
(1) gas-filtering device of the present utility model, by the setting of dedusting slide block and dust collection area, eliminates existing
The blowback step of device.
(2) gas-filtering device of the present utility model, when using, by dedusting slide block Lai appropriate thinning dust filter membrane, is kept away
Exempt from the process re-forming again after established dust filter membrane is removed completely by existing apparatus by blowback, namely before avoiding
The process of phase dust filter membrane formation stages poor filtration effect, thus improve efficiency of dust collection.
(3) upper surface of this utility model grain bed is apart from the lower surface 5～30mm of dust outlet, the powder in this position
Dirt filter membrane will not be turned down by dedusting slide block it is ensured that the thickness of dust filter membrane is suitable.
(4) device of the present utility model can be worked continuously, and effectively improves screening and dedusting method, improves dedusting further
Efficiency.
