Abstract
The utility model discloses a step type cut-off air inlet path of a bag type dust remover for treating the fume generated by a coal burning boiler. The structure of the utility model mainly comprises a pipeline main body, wherein one end of the pipeline main body is provided with an air inlet. The utility model is characterized in that one side of the pipeline main body is provided with a step type cut-off board, a step level on the step type cut-off board is arranged in a caliber gradually-reducing state along an airflow direction of the air inlet, and air outlets are respectively arranged on each step level of the step type cut-off board. The step type cut-off air inlet path is used in the bag type dust remover, the fume can be uniformly and orderly distributed in each unit filtering chamber so as to prevent the phenomena of vortex flow and turbulent flow from taking place, and thus, dust removing efficiency of the device can be improved and service life of the filter bag of the device can be prolonged.
Description
Technical field
The utility model relates to the bag-type dust collecting equipment that is mainly used to handle the flue gas that coal-burning boiler produces, and refers more particularly to the air intake passage in this equipment.
Background technology
In the bag-type dust collecting equipment of handling fire coal boiler fume, the main effect of air intake passage is: pending flue gas equilibrium is assigned to each unit filters in the bin.Its structure of air intake passage at present commonly used as shown in Figure 1, mainly comprise: pipeline body 1, the left end of pipeline body 1 are air inlet 11, and pipeline body 1 is provided with air outlet; Wherein the quantity of air outlet can be according to the size of pipeline body 1, and the actual needs of bag-type dust collecting equipment is determined, as indicating altogether among Fig. 1 three air outlets are arranged---12,13 and 14, now its operation principle is described as example, air intake passage shown in Figure 1 is also referred to as the diameter reduced air intake passage usually, its cross section can be circle or rectangle, after pending flue gas enters pipeline body 1 from air inlet 11, because its caliber is constantly dwindling, thereby at first nearly 1/3rd flue gas flows out from first air outlet 12, and enter into the unit that links to each other with this air outlet and filter bin; And the like, have about 1/3rd flue gas with that and flow out and enter into the unit that links to each other with this air outlet from second air outlet 13 and filter bin, remaining about 1/3rd flue gas flows out and enters into the unit filtration bin that links to each other with this air outlet from the 3rd air outlet 14 at last.But, in actual use, the air intake passage of said structure there is no ideal like this to the distribution condition of flue gas, flue gas is easy to produce eddy current and turbulent flow when flowing in the air intake passage of this structure, cause dust stratification and resistance increase in the pipeline body, and it is unbalanced to cause flue gas to distribute, thereby will inevitably increase the weight of the live load that certain or some unit filter bin, makes these unit filter the service life that filter bag in bins does not reach expection.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of can be better balanced notch cuttype that distributes flue gas air intake passage that dams.
The technical solution adopted in the utility model is: the described notch cuttype air intake passage that dams mainly comprises: pipeline body, and an end of pipeline body is an air inlet; Be characterized in: the side at pipeline body is provided with the notch cuttype intercepter plate, and along on the air intake airflow direction of air inlet, step deck on the notch cuttype intercepter plate is bore and dwindles the shape setting gradually, and air outlet is separately positioned on each step deck of notch cuttype intercepter plate.
A kind of further technical scheme of the utility model is: a kind of set-up mode of step deck is on the above-mentioned notch cuttype intercepter plate: step deck can impel the exhaust gas volumn that flows out from each air outlet to be equivalent to N/one of the exhaust gas volumn of pipeline body air inlet input, and wherein N is the air outlet quantity that is arranged on the notch cuttype intercepter plate.
The another kind of further technical scheme of the utility model is: the upside at each air outlet also is provided with deflector, and deflector is fixedly installed in the pipeline body.
The utility model has the advantages that: in bag-type dust collecting equipment, used the described notch cuttype air intake passage that dams, flue gas evenly and in an orderly manner can be assigned to each unit filters in the bin, avoided the generation of eddy current and turbulent phenomenon, thereby both can improve the efficiency of dust collection of equipment, again can prolongation equipment in service life of filter bag.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As Fig. 2, Fig. 3, shown in Figure 4, the notch cuttype described in the utility model air intake passage that dams mainly comprises: pipeline body 1, and an end of pipeline body 1 is an air inlet 11; Side at pipeline body 1 is provided with notch cuttype intercepter plate 2, and along on the air intake airflow direction of air inlet 11, step deck on the notch cuttype intercepter plate 2 is bore and dwindles the shape setting gradually---in the present embodiment, be provided with three step decks 21,22 and 23 altogether; Air outlet is separately positioned on each step deck of notch cuttype intercepter plate 2---in the present embodiment, be provided with three air outlets 12,13 and 14 altogether.In actual use, can determine the quantity of step deck and air outlet according to the actual needs of the size of air intake passage and bag-type dust collecting equipment.In addition, in the present embodiment, the set-up mode of the step deck on the notch cuttype intercepter plate 2 is: step deck 21,22 and 23 can impel from each air outlet 12,13 and 14 exhaust gas volumns that flowed out be equivalent to 11 inputs of pipeline body 1 air inlet exhaust gas volumn 1/3rd.In addition, in the present embodiment, the upside in each air outlet 12,13 and 14 also is respectively arranged with deflector 32,33 and 34, and these deflectors all are fixedly installed on respectively in the pipeline body 1.
The dam operation principle of air intake passage of the notch cuttype of said structure is: after pending flue gas enters in the pipeline body 1 from air inlet 11, air-flow is the multilayer layer stream mode and flows, along with moving ahead of air-flow, about 1/3rd air-flow is under the ladder between first step deck 21 and second step deck 22 dams the effect of face, and under the guiding of first deflector 32, enter into air outlet 12 with the laminar flow form; Remaining air-flow continues to move ahead, and under the ladder between second step deck 22 and the 3rd step deck 23 dams the effect of face, and under the guiding of second deflector 33, about 1/3rd air-flow also enters into air outlet 13 with the form of laminar flow; Remaining 1/3rd air-flow continues to move ahead, and under the guiding of the 3rd deflector 34, air-flow also enters into air outlet 14 with the form of laminar flow.So far, the total air-flow that enters from air inlet 11 respectively by each air outlet 12,13 and 14 backs, be assigned to the unit that is connected with each air outlet equably and filtered the bin, avoided the generation of eddy current and turbulent phenomenon, thereby both can improve the efficiency of dust collection of equipment, again can prolongation equipment in service life of filter bag.The effect of above-mentioned each deflector is that steering current enters into each air outlet more easily.
In addition, the notch cuttype described in the utility model air intake passage that dams is more suitable in handling the flue gas that dust concentration is little, the small particle diameter dust is on the high side.
