The specific embodiment
Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the specific embodiment of description of drawings the utility model at present.
Fig. 1 shows the main TV structure according to the spiral-flow type spark catcher of the utility model embodiment.As shown in Figure 1, according to the spiral-flow type spark catcher of the utility model embodiment, the spark that is used for removing smoke, said spiral-flow type spark catcher comprises: air inlet pipe 1 is used to insert flue gas; Cylindrical shell 4, the stem 41 of said cylindrical shell is connected with the afterbody of said air inlet pipe 1; Blast pipe 5 on the ash bucket, is used in discharging flue gas shown in being arranged on; Said air inlet pipe 1, said cylindrical shell 4, said ash bucket 6 and said blast pipe 5 are connected to form exhaust gases passes.Collect the ash bucket 6 of the dust in the said flue gas, promptly collect the collection bucket of dust, be connected the afterbody 43 of said cylindrical shell and be enclosed in outside the said blast pipe 5.Ash bucket 6 can in time be discharged the spark particle.
Said spiral-flow type spark catcher also comprises: be arranged on the spiral-flow type guide vane 2 in the said exhaust gases passes.
Spiral-flow type guide vane 2, promptly swirl vane is unpowered not rotating member, makes flue gas do rapid circular movement.Dust-laden rotation flue gas is thrown to the crude particle dust that wherein contains spark on the inwall of said air inlet pipe or said cylindrical shell under centrifugal action, and spark finally loses kinetic energy and produces sedimentation, discharges through said cylindrical shell, and can not enter into blast pipe.Said spiral-flow type guide vane 2 can be arranged in the said air inlet pipe 1.Spiral-flow type guide vane 2 is arranged in the air inlet pipe 1, so that the crude particle dust that contains spark is thrown on the inwall of said air inlet pipe 1, and away from blast pipe 5.Said spiral-flow type guide vane 2 is fixedly connected with deflection cone 3, and deflection cone 3 is a taper type, is arranged on the axial of spiral-flow type guide vane 2.Deflection cone 3 is convenient to processing and spiral-flow type guide vane 2 is installed, and also can play a part in addition the flue gas through spiral-flow type guide vane 2 is carried out water conservancy diversion.The external diameter of said spiral-flow type guide vane is welded on the inwall of air inlet pipe 1, and said spiral-flow type guide vane internal diameter is welded on the outer wall of deflection cone 3, thereby can make the crude particle dust that contains spark be thrown to the edge of exhaust gases passes, prevents that spark from getting into blast pipe.
Ash bucket 6 forms the dedusting space with said cylindrical shell 4, and the stem of said ash bucket is connected with the afterbody of said cylindrical shell 43, and the afterbody 43 of said ash bucket has end plate 61, and the dedusting space outside the said blast pipe 5 of said end plate 61 sealings is in order to avoid reveal.Said ash bucket 6 also comprises the dust outlet 63 that is positioned under the said blast pipe 5, like this, helps dust and discharges by deadweight.Further; The opening of the stem 41 of said cylindrical shell is less than afterbody 43 openings of said cylindrical shell, and when air inlet pipe was identical with the blast pipe caliber, periphery, the left side of blast pipe formed the space; Let spark same collision outer wall under action of centrifugal force in the eddy flow flue gas, produce sedimentation thereby lose kinetic energy.
Said air inlet pipe 1 is a cylindrical shape, and said blast pipe 5 is a cylindrical shape, and said cylindrical shell 4 is conically shaped or taper type tube, is convenient to like this make.The dead in line of said air inlet pipe 1 and said blast pipe 5 or parallel, like this, the direction of flue gas turnover is constant, drag losses is relatively low, can be directly installed in the horizontal pipe-line system, do not change pipe to, need not increase power newly can move, the scope of application is extensive.Certainly, the shape of said air inlet pipe 1, said cylindrical shell 4 and said blast pipe 5 is not limited to circle or taper, and other different shapes also can play the effect of exhaust gases passes.
The course of work of the utility model is following: spark catcher is arranged on the cleaning shaft before the sack cleaner import, and usually, this type spark catcher is that level is installed.The flue gas that contains spark enters into spiral-flow type guide vane 2 from air inlet pipe 1, and under the effect of spiral-flow type guide vane 2, flue gas is done rapid circular movement.Dust-laden rotation flue gas is under centrifugal action; The crude particle dust that wherein contains spark is thrown on the inwall of said air inlet pipe 1, cylindrical shell 4 and ash bucket top equipment; The dust that contains spark finally loses kinetic energy and produces sedimentation; Drop in the ash bucket 6 through said cylindrical shell 4 and to be collected, discharge then, and can not enter into blast pipe 5.On the other hand, eliminated the flue gas of spark and discharged, got into subsequent processing or further dedusting from blast pipe 5.The flow of flue gas circuit is short in this type spark catcher, and energy consumption is little; And this trap flexible configuration is convenient, can be directly installed in the horizontal pipe-line system, do not change pipe to, need not increase power newly can move, the scope of application is extensive.Textural seeing from spark catcher can also be used for the higher dust pelletizing system of dust contained flue gas concentration as the flue dust preseparator in addition, to capture the dust of larger particles, plays the function of gas-solid separating device in preparatory dedusting effect and the environmental project.
The above is merely the schematic specific embodiment of the utility model, is not in order to limit the scope of the utility model.For each part of the utility model can make up under the condition of not conflicting each other; Any those skilled in the art; Equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, having done and modification all should belong to the scope that the utility model is protected.
