The specific embodiment
The technical program is further illustrated as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of unit bag filter comprises housing, filter bag, discharge pipe and lower face plate: the housing inner chamber is divided into separate air inlet duct and exhaust passage; Isolate by filter bag between air inlet duct and exhaust passage; Lower face plate is at housing bottom, and described discharge pipe is connected to housing top, and the exhaust outlet connecting fan of described discharge pipe is characterized in that described filter pocket openings down; Lower face plate consists of air inlet duct through filter pocket openings to the cavity between the filter bag inwall; Filter bag outer wall to the cavity between discharge pipe consists of the exhaust passage; Also comprise the filter bag head motion and shake drive unit; Shake drive unit and connect driving filter bag head motion, the filter bag head motion connects the blind end of filter bag.
Described filter bag head motion and the effect of shaking drive unit are to drive the filter bag shake, can realize that the structure of this function has a lot, provides following optimal way in this programme in existing prior art:
The described drive unit that shakes is wobbling motor; Described filter bag head motion comprises curved bar and walking bar rod; Described hull outside is corresponding with filter bag blind end position goes out to have through hole, be inserted with axis of rocking in through hole, one end of axis of rocking connects the blind end of filter bag, the other end of axis of rocking connects walking bar rod by small rod, one end of this small rod and axis of rocking fixed-link; the other end and the walking bar rod of little side rod are rotationally connected, and small rod and axis of rocking meet at right angles; The output shaft of described wobbling motor is an end of curved bar fixedly, and an end of the other end of curved bar and walking bar rod is rotationally connected.
Described filter bag has identical a plurality of, and each filter bag blind end is connected with axis of rocking, have through hole corresponding to each axis of rocking on housing; The blind end of each filter bag is identical with the syndeton that walking bar rod connects by axis of rocking.
A kind of improvement is to be connected with ash bucket under described lower face plate; Have gas approach on ash bucket.
The another kind of improvement is to be connected with ash storage box under described lower face plate; Have gas approach on ash storage box.
In concrete the use, this dust-precipitator adopts the fabric composite bag of terylene woven (Polyester woven) usually, allows inlet temperature less than 120 ℃, and during less than or equal to 100g/Nm3, the outlet concentration of emission will be less than 100mg/Nm3 when entrance concentration.To the place of specific use is arranged, also can provide stainless steel or aluminum design, the unit bag collector of corrosion-resistant heatproof filtrate.
Basic structure is by shown in Figure 1, and it mainly contains following part and forms:
(1) casing: comprise housing, filter bag, access door, filter bag cuff, card, cabinet design endurance 2500Pa;
(2) outlet system of air: comprise blower fan and blower fan-matched motor;
(3) head motion: comprise and shaking with reducing motor, curved bar, walking bar rod, axis of rocking (or claiming the filter bag suspended axle);
(4) air inlet and ash discharge part: can be divided into three kinds:
Shown in Fig. 2-a, the bottom is open type, during deashing dust directly from card draw off enter storehouse, storehouse etc., card flange directly seat in the storehouse, the storehouse exhaust outlet, exhaust directly by the card hole, enter filter bag.
Shown in Fig. 2-b, can descend the ash bucket, mainly be used in the airborne dust point of bottom of the reservior and conveying equipment;
Shown in Fig. 2-c, with ash storage box, be mainly used in the not high clean body of ventilating opening gas of concentration.
The operation principle of this dust-precipitator is described as follows:
Dusty gas enters ash bucket or ash storage box by air inlet, by the card hole or directly three kinds, hole of card mode enter filter bag.As shown in Fig. 2 a～Fig. 2 c, dusty gas sees through filter bag and becomes pure qi (oxygen), enters casing, then is drained by blower fan through the casing upper air vent.The long-pending inner surface that is attached to filter bag of dust, and constantly increase, make the resistance of bag collector constantly increase.When resistance rises to 1500～2000Pa, work in order to make bag collector, need regularly to remove the dust on filter bag.
During concrete deashing, at first close blower fan, start wobbling motor, wobbling motor drives walking bar rod, makes about axis of rocking and comes back rotation, and filter bag just is the ripple state, makes dust releasing, and then draws off.The deashing state as shown in Figure 3.Deng deashing is complete namely stop shaking after, restart blower fan, make bag collector restart work, above-mentioned action is automatically controlled by controller and is completed.Be in operation, if find that exhaust outlet has a large amount of dust to overflow, namely broken bag may be arranged, need in time to change.Check can open when changing bag access door, directly enter indoor.
As another kind of scheme, wobbling motor also can be replaced by common reducing motor, is connected with eccentric wheel and can plays same effect on the output shaft of this motor.
