Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, the dust settling tower 100 that the utility model provides, comprise an open-topped housing 1, housing 1 inner upper is laterally fixed with one for the rotating flow cone 2 of flue gas eddy flow, be provided with the smoke outlet tube 3 of sealing by housing 1 bottom centre below rotating flow cone 2, bottom housing 1, side is connected with ash discharging gear 4.Vertically place when this dust settling tower 100 uses, flue gas pipeline (the prior art that the open top of housing 1 is connected with smelting furnace outlet, not shown) be communicated with, smoke outlet tube 3 is communicated with follow-up dust pelletizing system, be provided with bottom Connection Block 31 bottom smoke outlet tube 3, smoke outlet tube 3 is connected with follow-up dust pelletizing system by bottom Connection Block 31; It is inner that the flue gas that self-thermo furnace outlet is extracted out enters housing 1 by open top, produce through rotating flow cone 2 and rotate and flow downward, under the effect of rotary centrifugal force, crude particle dust containing spark is thrown in the inner walls below rotating flow cone 2, rotary power is lost by the crude particle dust containing spark of colliding, along the downward sedimentation of housing sidewall, discharge dust settling tower 100 eventually through the ash discharging gear 4 bottom housing 1; And be positioned at directly not rotating containing the fine particle dusts of spark of center and descend through smoke outlet tube 3 and enter follow-up dust pelletizing system (prior art, not shown).Crude particle dust containing spark is discharged by dust settling tower 100, avoids entering follow-up dust pelletizing system and causes potential safety hazard.
Further, as shown in Figure 1, Figure 3, rotating flow cone 2 comprises the rotating flow cone inner core 21 being positioned at central part, the eddy flow cone 22 diametrically going up convergent is fixedly installed above rotating flow cone inner core 21, rotating flow cone urceolus 23 is coaxially arranged with outside rotating flow cone inner core 21, between rotating flow cone inner core 21 and rotating flow cone urceolus 23, circumferential uniform intervals is provided with the swirl vane 24 of multiple inclination, and the incline direction of each swirl vane 24 is identical with angle of inclination.Rotating flow cone urceolus 23 is fixedly installed on housing 1 inner upper.The flue gas entering housing 1 inside flows in the gap between multiple swirl vane 24 along the surface guiding of eddy flow cone 22, under the effect of swirl vane 24, flue gas produces eddy flow, and suffered by the dust that particle is larger, centrifugal force is larger, more easily by the housing sidewall of getting rid of to swirl vane 24.Therefore, the crude particle dust containing spark loses rotary power, and along the downward sedimentation of housing sidewall, the fine particle not containing spark concentrates on casing center place, rotates and drops in smoke outlet tube 3.
As shown in Figure 1 and Figure 2, in the present embodiment, housing 1 comprises the approach cone section 11, the interlude 12 of tubular and the dust processing section 13 that connect successively from top to bottom, approach cone section 11 diametrically lower cumulative.Approach cone section 11 top is provided with the first adpting flange 111, and the flue gas pipeline that housing 1 is connected with smelting furnace outlet by the first adpting flange 111 is connected.Rotating flow cone 2 is laterally fixedly installed on the inside upper part of interlude 12.It is an inclined-plane 131 bottom dust processing section 13, inclined-plane 131 is provided with and seals for smoke outlet tube 3 the outlet via hole (not shown) passed through, lose the coarse granule containing spark of rotary power, fall on the inclined-plane 131 bottom dust processing section 13 along the downward sedimentation of housing sidewall, particle on inclined-plane 131 is slipped to inclined-plane lowermost end under gravity, discharges dust settling tower 100 eventually through the ash discharging gear 4 bottom housing 1.
Further, as shown in Figure 1, ash discharging gear 4 comprise be communicated with bottom housing 1 go out ash bucket 41, go out bottom ash bucket 41 and connect an ash-discharging device 42, ash-discharging device 42 can be unloading valve (prior art does not repeat them here).
From the above mentioned, dust settling tower of the present utility model, structure is simple, utilize the centrifugal action of rotating flow cone, spark particle in abundant separating flue and big dust particle, by ash-discharging device discharge line, avoid the adverse effect of spark to dust pelletizing system, improve the security that dust pelletizing system is run; This dust settling tower is vertically install, and efficiency of dust collection is high, and floor space is little, flexible configuration, is convenient to be connected with cleaning shaft, and the scope of application is wider.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
