The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Like the structure of the expressed the utility model of Fig. 1, Fig. 2, be environment-friendly type C-KSV whirlwind tube, described whirlwind tube comprises spiral case 2, cylinder 3, cone 4 from top to bottom, establishes inner core 1 in the described spiral case 2, air inlet 8 is established in the outside of described spiral case 2.
The utility model utilizes cold model test based on the present state of the art, has analysed in depth gas motion characteristics in the whirlwind tube, through optimizing whirlwind barrel structure form, improves gas solid separation efficient, does not increase even reduce simultaneously SR.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective; Be implemented under the prerequisite that does not increase even reduce SR; Improve the goal of the invention of gas solid separation efficient, the technical scheme that the utility model is taked is:
Like Fig. 1, shown in Figure 2; The environment-friendly type C-KSV whirlwind tube that the utility model provided is provided with cone hole enlargement structure 7; Described cone hole enlargement structure 7 is: described cone 4 is divided into upper cone 5 and lower cone 6, described upper cone 5 and lower cone 6 be big end up, small end down; Described upper cone 5 and lower cone 6 be coaxial to be connected and to communicate, and the outside diameter of described lower cone 6 is greater than the end diameter of upper cone 5; Establish the seal face of level between the port of described lower cone 6 and the described upper cone 5.
This whirlwind tube has designed unique " cone hole enlargement structure " at the cone middle part, and the material under will collecting when effectively having avoided gas " to turn back " is kicked up once more, has improved gas solid separation efficient.Improve 2%～5% than traditional whirlwind tube separative efficiency, pressure loss coefficient reduces by 25%～30% than traditional whirlwind tube.
The bottom of described air inlet 8 is provided with the inclined plane, and the incline direction on described inclined plane is from outside to inside, from high to low, make described air inlet 8 two sides be shaped as pentagon.
The angle of described inclined plane and horizontal plane is 50 °.Whirlwind tube air inlet 8 has effectively reduced the dust accumulation for the pentagonal configuration with 50 ° of inclination angles, makes system's operation more stable.
As shown in Figure 3, dusty gas is the spiral case 2 that pentagonal air inlet 8 gets into the whirlwind tubes through the side, under the squeezing action of gravity, the back dusty gas that gets into, under the guiding of spiral case 2, forms the downward screw of high-speed rotational.In this process, material is under the effect of centrifugal force and whirlwind tube limit wall friction power, and the wall spiral moves downward along the limit.When dusty gas arrived whirlwind tube cone 4, gas " was turned back " under the reflex of cone 4 and is moved upward, and discharged from blast pipe, and then wall continues to move downward dust along the limit.
Different according to cone hole enlargement structure and inner core height, the whirlwind tube of the utility model is divided into two types of A, B again.The dust-collecting efficiency of these two types of whirlwind tubes and drag losses are different and different because of its inner core height and cone hole enlargement version.
Like Fig. 1 and shown in Figure 6, the design feature of said A type whirlwind tube is:
The port of the lower end of described upper cone 5 is lower than the port of the upper end of described lower cone 6.
The bottom of described inner core 1 is lower than the extreme lower position of spiral case 2.
Like Fig. 2 and shown in Figure 7, the design feature of said Type B whirlwind tube is:
The port of the upper end of the port of the lower end of described upper cone 5 and described lower cone 6 at grade.
The bottom of described inner core 1 is lower than the extreme lower position of spiral case 2.
Described A, two types of whirlwind tubes of B are applied in the top and the bottom of precalcining system respectively, i.e. C1 and C5 level whirlwind tube (being one-level whirlwind tube and five-stage whirlwind tube).
Above-mentioned two kinds of whirlwind tubes are used for the preheating predecomposition of cement slurry, and the cement slurry after the homogenizing fully disperses back entering preheater through the material-strewing device that C2, C1 whirlwind tube connect on the airduct, in preheater with hot gas abundant heat exchange under suspended state.To the Category Four cyclone tube, go into dore furnace, carbonate decomposes in a large number under the hot environment in dore furnace.Material after the decomposition is gone into five-stage whirlwind tube (C5) separated and collected, then through kiln tail smoke-box feeding rotary kiln.
Comparison diagram 6 and Fig. 7, the height of A type whirlwind tube is much larger than Type B; The diameter of Type B whirlwind tube is much larger than the A type.Equally, the inner core height is different; The lower cone connected mode is different in cone hole enlargement place.
Fig. 4 is whirlwind tube dust-collecting efficiency and wind speed graph of relation.As can be seen from the figure, on the whole, the cross section wind speed is between 5m/s to 6.7m/s, and the little separative efficiency on the contrary of wind speed is high, this explanation, and the technical scheme of employing the utility model can suitably reduce wind speed, the power consumption of minimizing system; In addition, solid-gas ratio raises, and separative efficiency descends to some extent, but influence is very little.
Fig. 5 is a whirlwind tube resistance coefficient curve map.As can be seen from the figure, when the import wind speed rose, whirlwind tube resistance coefficient did not obviously rise.
Table one: the whirlwind tube dust-collecting efficiency thermal technology nominal data of the utility model
| ? | C1 outlet dustiness (g/Nm 3) | C1 dust-collecting efficiency (%) |
| Project one | 62.11 | 93.72 |
| Project two | 64.88 | 94.13 |
What C1 promptly represented in the table is the one-level whirlwind tube at the top of precalcining system.
The technical scheme of the utility model is applied to 5000t/d grog line project, through runtime verification, can find out that through thermal technology's nominal data the dust-collecting efficiency of this whirlwind tube is more than 93%.
More than combine accompanying drawing; The utility model has been carried out exemplary description; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the improvement of the various unsubstantialities that the method design of having adopted the utility model and technical scheme are carried out, or the design of the utility model and technical scheme are directly applied to other occasion without improvement, all within the protection domain of the utility model.
