The specific embodiment
Referring to Fig. 1-4, the dust-precipitator supporting leg 1, air valve 2, ash bucket 3, the middle casing 4(Rose Box that according to off-line of the present invention, online ash removal, automatically switch), converge bellows 5, upper box 6(Gas-cleaning box), soot cleaning system, cat ladder 8, guardrail 9, gather dust and consider bag 10, bag cage 11, lift valve 12, card 13 and dividing plate 14, air inlet and air outlet.Deduster upper box and middle casing are rectangular, and upper box and middle box house form respectively a plurality of chambers by means of dividing plate 14, and middle casing comprises a plurality of filtration locellus, and upper box comprises a plurality of air-purifying chambers.Card 13 is provided with several card holes, connects the worry bag assembly that worry bag and bag cage form under the card hole.Dust-precipitator air inlet and air outlet are provided with pressure sensor, and pressure sensor is sent to electric-control system by the pressure signal measured.During dust-precipitator work, dust-contained airflow enters ash bucket from air inlet, after the baffle plate during the part dust clashes between casing and ash bucket, falls into ash bucket, and all the other dust enter middle casing with air-flow, then consider bag by gathering dust and enter upper box, now dust is trapped within to gather dust and considers the bag outer surface.Clean gas enters the remittance bellows via upper box, then from air outlet, discharges.
Preferably, identical according to the horizontal cross-sectional area of a plurality of filter chambers of deduster of the present invention, but the card hole gross area of each chamber is different, (for example, each card hole area is identical, and the number difference is set; If the number difference is set, the card hole area that certain chamber adopts does not wait, and now considers yet difference of bag assembly; Preferably the former).In one embodiment, from the most close air inlet one side to, away from air inlet one side, the card hole gross area of chamber increases successively; In another embodiment, the card hole area of the locellus in the middle of being positioned at is greater than the card hole area of the locellus on both sides.The purpose of this setup is, dust-contained airflow enters ash bucket from air inlet, and the gas pressure distribution in ash bucket is inhomogeneous, and at pressure, different places selects different card hole areas can cause less harmful effect when off-line ash-clearing; The position and the Angular correlation that as for the selection of the first two embodiment, arrange with air inlet.
More preferably, according to the horizontal cross-sectional area difference of a plurality of filter chambers of deduster of the present invention, now the card hole area on unit are keeps constant, and it is identical that single card hole area also can keep, and this is very favourable for manufacture.In one embodiment, from the most close air inlet one side to, away from air inlet one side, the horizontal cross-sectional area of chamber (because the card hole area on unit are keeps constant, the card hole area also is proportional to the horizontal cross-sectional area of chamber) increases successively; In another embodiment, the horizontal cross-sectional area of the locellus in the middle of being positioned at is greater than the card hole area of the locellus on both sides.The purpose of this setup is the same.
When needing deashing, (for example can monitor by the pressure of pressure sensor), for certain chamber, when air outlet pressure is not less than setting value with respect to the pressure differential of air inlet, the deashing chamber lift valve cuts out, deashing chamber is considered bag and is not worked, dust-precipitator is carried out off-line ash-clearing, adopts soot cleaning system, and this system can be for example that pulse reverse divides the blowing-out apparatus for ash; As shown in Figure 3, now air-flow passes through from non-deashing chamber stream condition.When off-line ash-clearing a period of time, because resistance increases, air outlet pressure is with respect to the pressure differential of air inlet during lower than setting value, the deashing chamber lift valve is opened, (lift valve is opened rear deashing chamber and is produced flow perturbation to carry out online ash removal, can shake off to consider the dust on bag), deashing chamber is considered bag and is devoted oneself to work.When air outlet pressure is not less than setting value with respect to the pressure differential of air inlet again, can be for this chamber off-line ash-clearing again, online ash removal during afterwards lower than setting value; Go round and begin again, can select suitable cycle times, guarantee that the deashing chamber deashing more thoroughly gets final product.After this, then carry out aforesaid operations for other chambers, until all the deduster sub-room cleaning is complete.Associative operation can be completed by electric-control system.Preferably, air outlet pressure with respect to the pressure differential setting value of air inlet is-1000Pa.Because air outlet pressure can be not excessive with respect to the pressure differential absolute value of air inlet, the wearing and tearing of considering bag have therefore been reduced.
Preferably, when the card hole of each chamber gross area is different, at first from that chamber of card hole gross area minimum, start the deashing operation, by area, according to order from small to large, select locellus to carry out the deashing operation.Start deashing from that chamber of card hole gross area minimum like this and can effectively reduce the pressure differential absolute value of air outlet pressure with respect to air inlet, and then also just can reduce the wearing and tearing of considering bag, the dust-precipitator air-flow is more steady simultaneously.
Can realize that according to deduster of the present invention off-line, online ash removal automatically switch, make the utilization rate of dust-precipitator be improved, saved equipment usage space, to have extended service life, the dust-precipitator air-flow of considering bag more steady.
