In figure, have: air inlet 1, ash bucket 2, casing 3, cloth bag 4, deflector 5, air vent 6.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail.
As shown in Figure 1, the guiding device of a kind of sack cleaner of the present invention, comprises ash bucket 2, casing 3, cloth bag 4 and n deflector 5.Ash bucket 2 is fixedly connected on the below of casing 3.The base plate of casing 3 is provided with n+1 row air vent 6.On the base plate of casing 3, evenly lay a plurality of air vents 6, air vent 6 is array distribution.Cloth bag 4 is arranged in casing 3, and one end of cloth bag 4 is fixedly connected on the base plate of casing 3.The corresponding air vent 6 of each cloth bag 4, air vent 6 is communicated with ash bucket 2 and cloth bag 4.Deflector 5 is arranged in ash bucket 2, and deflector 5 is fixedly connected on the wall of ash bucket 2.Between deflector 5 and casing 3 base plates, there is space.The wall of ash bucket 2 is provided with air inlet 1, and the plate face of deflector 5 is relative with air inlet 1.Along gas approach axis in air inlet 1, deflector 5 is between two adjacent row air vents 6.N is more than or equal to 1 integer.
In the guiding device of said structure, deflector 5 is for shunting gas.The diversed plate 5 of gas passing into from air inlet 1 is shunted for the first time, portion gas upwards flows along deflector 5, flow to the space between deflector 5 and casing 3 base plates.Space between each deflector 5 and casing 3 base plates communicates.Therefore, the gas that flow to the space between deflector 5 and casing 3 base plates, under the effect of pressure separately, can flow mutually, realizes shunting for the second time, then enters in cloth bag 4.After shunting for the first time and shunting for the second time, the speed of the gas passing into from air inlet 1 obviously declines, thereby has reduced the speed that air-flow enters casing, has alleviated the impact of air-flow to cloth bag 4.After shunting for the first time, another part gas flows downward along deflector 5, is being mingled with the ash particle that diversed plate 5 stops in this gas.After the diversed plate shunting of this portion gas, speed is significantly successively decreased, and while arriving ash bucket 2 rear surface, speed is very little, is not enough to produce reflux.Therefore, this portion gas there will not be backflow in ash bucket 2.
Further, the angle between a described n deflector 5 and casing 3 base plates, along gas approach axis in air inlet 1, increases successively.Deflector 5 from air inlet 1 away from more, the angle between itself and casing 3 base plates is larger.Air-flow enters in ash bucket 2 by air inlet 1, and air-flow is jet, decrease of speed, so deflector 5 along air flow direction setting, and along with the reducing of air velocity, the angle between deflector 5 and casing 3 base plates increases according to this, makes air-flow enter uniformly each cloth bag.
As preferably, the angle between described deflector 5 and casing 3 base plates is 60 °-90 °.From 90 ° of deflector 5 farthest of air inlet 1 and the angles between casing 3 base plates.For example, the angle of four deflectors 5 in Fig. 1 is followed successively by 60 °, 70 °, 80 °, 90 °.Like this, deflector 5 has become 5 by the gas barrier passing into from air inlet 1, makes gas pass into cloth bag 4 more even.
Further, the top of described deflector 5 than the bottom of deflector 5 near air inlet 1.Because deflector 5 blocks the effect of air-flow, a part of big particle collision is trapped on deflector 5, and deflector 5 is tilted to down the landing that contributes to particle.If deflector 5 is greater than 90 ° with base plate angle, air-flow blows afloat deposited particles on deflector 5, produces reentrainment of dust, is unfavorable for dedusting.
Further, the height of described deflector 5, along gas approach axis in air inlet 1, increases successively, and above being all positioned at air inlet 1 bottom from the bottom of n-1 nearest deflector 5 of air inlet 1.For example, increase progressively highly successively 15-25mm.Air-flow enters in ash bucket 2 and is jet state, impacts first deflector, and a part of gas rises along deflector, and a part of γ-ray emission streams.Therefore, deflector 5 is increased highly successively, a rear deflector is tackled streaming of last deflector, until gas is all tackled and entered in cloth bag 4.
Further, in described deflector 5 from the bottom of air inlet 1 deflector farthest, with the bottom of air inlet 1 in the same horizontal line, or be positioned at the below of the bottom of air inlet 1.From the bottom of air inlet 1 deflector 5 farthest, with the bottom of air inlet 1 in the same horizontal line, or be positioned at the below of the bottom of air inlet 1.Like this, the gas passing into from air inlet 1, can directly not impact on the wall of ash bucket 2.First the gas passing into from air inlet 1 can directly flow to each deflector 5.This is conducive to be avoided the generation of backflow.
Further, described deflector 5 is steel plate.The shock-resistant ability of steel plate is strong, so make deflector 5 with steel plate, can bear the gas impact that air inlet 1 passes into.
Further, the top of each described deflector 5 is near the row air vent 6 after leaning in adjacent two row air vents 6.Air-flow is tackled by deflector 5, along deflector 5, rises, and air-flow enters in the space between deflector 5 and casing 3 base plates, shunts for the second time, and then flows in cloth bag 4.If the top of deflector 5 is near a row air vent 6 forward in adjacent two row air vents 6, the air-flow rising along deflector 5 so can directly wash away cloth bag 4 bottoms, produces larger load, wearing and tearing cloth bag 4.A row air vent 6 after leaning in adjacent two row air vents 6, refers in adjacent two row air vents 6 the row air vent 6 away from air inlet 1.
The course of work of the guiding device of said structure is: from the air inlet 1 of ash bucket 2, pass into gas, gas enters ash bucket 2, flows to the deflector 5 relative with air inlet 1.Deflector 5 is divided into n+1 region by air-flow, enters uniformly in the cloth bag 4 of casing 3.As shown in Figure 1, air-flow is divided into five parts under the effect of deflector 5, and every part, along the deflector 5 of diverse location, is moved obliquely with different inclination angles.By deflector 5 is set in ash bucket 2, for the feature of sack cleaner air-flow uneven distribution, the air-flow of deduster entrance is improved.In common deduster, deflector is not set, inlet air flow, because wind speed is larger, produces strong jet phenomenon in deduster porch.Air-flow enters the base plate that impacts deduster in ash bucket, and a part of air-flow with larger speed fast rise, forms transversal flow to cloth bag along base plate.Another part air-flow flows downward along base plate, in ash bucket, forms significantly and refluxes.And in patent of the present invention, after the deflector 5 of the air-flow passing into from air inlet 1 by one group of differing tilt angles and differing heights, first part big particle strikes diversed plate 5 trappings of deflector 5, and then landing is to ash bucket, secondly air-flow enters respectively in the gap between deflector 5 and casing 3 base plates by deflector 5, under gas pressure separately, redistribute uniformly air-flow, flow in cloth bag 4.Air-flow has weakened by the shunting action of deflector 5 phenomenon that in ash bucket, appearance refluxes, and avoids reentrainment of dust.After shunting, air velocity is relatively little, and air-flow can not produce serious impact to cloth bag after entering deduster, and deduster interior flow field is also more even, not only improves the efficiency of dust collection of deduster, also increases the service life of cloth bag.
