Abstract
The utility model provides a kind of vortex type pipeline turning device, and comprising that to be arranged side by side cross section be circular straight tube and cross section is circular straight tube, and straight tube top is provided with whirlwind spiral case, and whirlwind spiral case connects with straight tube by changing elbow.Whirlwind spiral case is connected with straight tube by funnel shaped transition conduit.This turning device runs downwards with helical manner after making the high-temperature flue gas carrying material enter whirlwind spiral case, there is certain centrifugal effect, eliminate the condition of inside deposition material, fundamentally completely eliminate the phenomenons such as solid accumulation, blocking, skinning, improve system running rate.More importantly, the material carried due to flue gas runs with helical manner, and material extended to some extent in the device internal stops time, is conducive to the abundant decomposition of raw material, thus stabilizes thermal regulation, improve grog yield and quality.
Description
Technical field
The utility model belongs to cement equipment technical field, relates to a kind of vortex type pipeline turning device for cement decomposing furnace gooseneck.
Background technology
Dore furnace in cement precalcining system is connected by tube connector (being usually gooseneck) with between C5 cyclone cylinder, and its inside is for carrying the high-temperature flue gas of raw material, and operating temperature is generally at 860 DEG C ~ 950 DEG C.The effect of gooseneck is the space effectively utilizing preheater framework when not increasing frame height, increases dore furnace volume, extends the time of staying of material in dore furnace, improves the resolution ratio into kiln raw material.Common practices is that decomposition furnace outlet upwards connects straight tube, then through 180 ° of dried shrimp elbows, then connects straight tube downwards, is connected with C5 cyclone cylinder by a reducing bend.
Existing 180 ° of dried shrimp elbows each section of bottom angle is not respectively 0 ° ~ 60 ° not etc., the high-temperature material carried in flue gas is easily piled up at the position that bottom angle is less, block and skinning, draught area is caused to reduce, thermal regulation is unstable, clear up very difficult, finally affect the running rate of kiln system and the yield and quality of grog.
Summary of the invention
The purpose of this utility model is to provide a kind of vortex type pipeline turning device, is not easy to pile up high-temperature material, avoids blocking and skinning.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of vortex pipeline turning device, comprising that to be arranged side by side cross section be circular straight tube and cross section is circular straight tube, and straight tube top is provided with whirlwind spiral case, and whirlwind spiral case connects with straight tube by changing elbow.
The utility model turning device adopts circle change side conversion elbow and whirlwind spiral case, the material that high-temperature flue gas is carried runs downwards with helical manner after entering whirlwind spiral case, there is certain centrifugal effect, eliminate the condition of inside deposition material, fundamentally completely eliminate the phenomenons such as solid accumulation, blocking, skinning, improve system running rate.More importantly, the material carried due to flue gas runs with helical manner, and material extended to some extent in the device internal stops time, is conducive to the abundant decomposition of raw material, thus stabilizes thermal regulation, improve grog yield and quality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, existing 180 ° of dried shrimp elbows are formed by connecting by multiple merogenesis 1, the bottom angle α of each merogenesis 1 be 0 ° ~ 60 ° not etc.The high-temperature material carried in flue gas is easily piled up at positions such as bottom angle less 0 ° or 30 °, is blocked and skinning, and cause draught area to reduce, clear up very difficult, thermal regulation is unstable, finally affects the running rate of kiln system and the yield and quality of grog.In order to overcome problems of the prior art, the utility model provides a kind of structure vortex type pipeline turning device as shown in Figures 2 and 3, is not easy to pile up high-temperature material, avoids blocking and skinning.It is circular straight tube 1 and cross section is circular straight tube 6 that this turning device comprises the cross section be arranged side by side, and straight tube 6 top is provided with whirlwind spiral case 4, is connected between whirlwind spiral case 4 with straight tube 6 by funnel shaped transition conduit 5; The other end of whirlwind spiral case 4 connects with one end of conversion elbow 3, and the other end of conversion elbow 3 connects with straight tube 2.
Conversion elbow 3 is the elbow of circle change side.Conversion elbow 3 is connected with horizontal rectangular (or polygon) import of whirlwind spiral case 4.The downward bottom of whirlwind spiral case 4 is that circular straight tube 6 is connected by funnel shaped rebound 5 and cross section below, completes 180 ° turn to.
The helix of whirlwind spiral case 4 is made up of involute, spiral of Archimedes and excentric camber line.
During use, be connected by the other end of straight tube 1 with decomposition furnace outlet, the other end of straight tube 6 is connected with C5 cyclone cylinder.The high-temperature flue gas carrying material upwards enters through decomposition furnace outlet the straight tube 2 that cross section is circle, whirlwind spiral case 4 is entered through conversion elbow 3, run downwards with helical manner in whirlwind spiral case 4, there is certain centrifugal effect, eliminate the condition of material in inside deposition, C5 cyclone cylinder is entered again through funnel shaped transition conduit 5 and straight tube 6, completely eliminate the possibility of the inner dust stratification of turning device, fundamentally completely eliminate the phenomenons such as solid accumulation, blocking, skinning, improve kiln system running rate.Meanwhile, the material carried due to flue gas runs with helical manner, extends the time of material in device internal stops, is conducive to the abundant decomposition of raw material, thus stabilizes thermal regulation, improve grog yield and quality.
