The specific embodiment
The core of gas solid separation technology is how to realize separating of solid matter and gas, and solid matter is meant the dust in material and the dust pelletizing system of being transferred in the air-transport system in the present invention.
As shown in Figure 1, the present invention adopts such method to realize separating of solid matter and gas: in an air-transport system or dust pelletizing system, after air-flow carries solid matter and enters horizontal sedimentation pipe 2 along conveyance conduit 1, at first, utilize 2 pairs of solid matters of horizontal sedimentation pipe to carry out dynamic horizontal sedimentation, by horizontal sedimentation, most of solid matter is moved ahead along horizontal sedimentation pipe 2 bottoms, after decelerator 3 decelerations, solid matter enters with air-flow and separates casing 4, solid matter is separating casing 4 dependence deadweight and inertia force and flow separation, send system by gas lock 8, after air-flow after the separation then further filters through filter plate 5, via discharge duct 7 dischargings.
As shown in Figure 2, in the present embodiment, horizontal sedimentation pipe 2 is that length is the square-section pipeline of L1 and inner wall smooth, and the width of horizontal sedimentation pipe 2 is A, highly is B.Horizontal sedimentation pipe 2 horizontal positioned, an end links to each other with conveyance conduit 1, the other end with separate casing 4 and link to each other.Wind speed in the horizontal feed pipeline 5 must guarantee that material can produce sedimentation phenomenon but do not produce depositional phenomenon in course of conveying, and according to the concrete condition of handling solid matter, the wind speed of horizontal feed pipeline 5 is generally 2～14m/s.For the ease of the solid matter sedimentation, the length L 1 of horizontal sedimentation pipe 2 generally is not less than 5～25 times of height B of horizontal sedimentation pipe 2.
Separating casing 4 is closed containers, the cross dimensions of separating casing 4 is much larger than horizontal sedimentation pipe 2, and shape is bottom-up magnify gradually horn-like, and gas lock 8 is equipped with in the bottom of separating casing 4, gas lock 8 makes solid matter can discharge separation casing 4, and air-flow can not pass through.The length L 2 of separating casing 4 generally is not less than 5 times of height B of horizontal sedimentation pipe 2, guaranteeing that filter plate 5 has enough flow areas, thereby reduces wind speed, avoids solid matter to be taken away by air-flow.The height B 1 of separating casing 4 is not less than 5 times of height B of horizontal sedimentation pipe 2, to guarantee the separating casing 3 inner air-flow vortex states that are easy to the minute solid phase separating substances that form.
The upper angled of separating casing 4 is equipped with filter plate 5, air enters discharge duct 7 necessary filtrations through filter plate 5 from separating casing 4, in gas material piece-rate system, filter plate 5 can be made with orifice plate, web plate, its open-work rate is not less than 30%, in dust pelletizing system, filter plate 5 can be made with filter cloth, filter paper.
For avoiding filter plate 5 to be stopped up by solid matter, the lee face of filter plate 5 is equipped with plurality of rows shower nozzle 6, utilizes the compressed air filter plate 5 of regularly jetting, and makes filter plate 5 keep unimpeded.
Principle of the present invention is such: the air-flow that carries solid matter is carried along conveyance conduit 1, enters horizontal sedimentation pipe 2.After air-flow carries solid matter and enters horizontal sedimentation pipe 2, because of the wind speed in the horizontal sedimentation pipe 2 low than conveyance conduit 1, enter horizontal sedimentation pipe 2 back speed reductions and progressively stable so contain the solid matter air-flow, at this moment solid matter mainly is subjected to air-flow thrust forward, and lost the buoyancy that makes progress, therefore solid matter progressively compiles to the bottom of horizontal sedimentation pipe 2 under the effect of self gravitation, and along with solid matter progressively compiles to the bottom of horizontal sedimentation pipe 2, air-flow is more stable, especially volume is big for most of solid matter, the solid matter that quality is big, under the drive of air-flow, advancing in bottom along horizontal sedimentation pipe 2, has finished the horizontal infall process of solid matter in horizontal sedimentation pipe 2.Its speed in horizontal sedimentation pipe 2 is adjusted according to the quality size of solid matter.
The place ahead of horizontal sedimentation pipe 2 is to separate casing 4, after solid matter is finished infall process through horizontal sedimentation pipe 2, bottom along horizontal sedimentation pipe 2 directly enters separation casing 4, the cross dimensions of separating casing 4 is much larger than horizontal sedimentation pipe 2, after air-flow enters and separates casing 4, the air-flow on top directly passes filter plate 5, through discharge duct 7 emptyings, other air-flow moves on, along with increasing air-flow passes material baffle 4, the throughput that moves on is more and more littler, and speed is also more and more lower, forms the air-flow vortex shown in the arrow among Fig. 3 at last.In this process, filter plate 5 is finished the filtration to air-flow, filter plate 5 has played uniform air flow action usefulness simultaneously, because the gas channel of filter plate 5 has windage to a certain degree, the pressure reduction of filter plate 5 both sides is stable, therefore, filter plate 5 air quantity everywhere is that this is a necessary condition of guaranteeing the good separation effect uniformly.
Solid matter along the bottom of horizontal sedimentation pipe 2 enter separate casing 4 after, move ahead with air-flow continuation level, the air-flow on top is near filter plate 5, must at first pass filter plate 5, filter plate 5 tilts to place along airflow direction, each just air-flow of the most close filter plate 5 of sub-fraction can pass filter plate 5, when these air-flows change direction of advance, the holder power that makes progress that solid matter is formed is very little, be not enough to change the direction of advance of solid matter, though and the solid matter quality is very little, when high-speed motion, there is inertia force equally.Solid matter moves on the air-flow that level moves ahead, along with increasing air-flow passes filter plate 5, air velocity more and more slower, solid matter has progressively lost the thrust of air-flow, lost simultaneously the holder power of horizontal sedimentation pipe 2 base plates again, more and more far away from the distance of filter plate 5, solid matter falls at the effect lower edge of self gravitation and inertia force parabola, finish and the separating of air-flow, send by the gas lock 8 that separates casing 3 bottoms.
Air-flow can think that the speed of the two is identical with solid matter when horizontal sedimentation pipe 2 moves ahead, air-flow carry solid matter enter separate casing 3 after, air flow slows will slow down faster than solid matter speed, the solid matter self inertia plays a major role in the motion process of solid matter like this, and the influence of air-flow is more and more littler.
Air-flow enters when separating casing 4 because the diffusion phenomena that the sectional area variation takes place also help separating of solid matter and air-flow from horizontal sedimentation pipe 2.
It is very big to the separating effect influence of solid matter and air-flow to form desirable air-flow vortex state in separating casing 4, the air-flow vortex state should be stable, remain shape shown in the arrow and direction of rotation among Fig. 1, separate casing 4 inner sides near horizontal sedimentation pipe 2 like this and remain air-flow upwards, opposite side remains downward air-flow.The solid matter of molecule is difficult for falling in separating casing 4, the solid matter that does not fall is taken up by air-flow in the side near horizontal sedimentation pipe 2 and moves upward, meet with the horizontal gas flow of horizontal sedimentation pipe 2 outputs, and the speed that the air velocity of horizontal sedimentation pipe 2 outputs rises much larger than air-flow vortex, solid matter can not pass through the horizontal gas flow of horizontal sedimentation pipe 2 outputs, can be driven by air-flow and move downward once more, therefore, the solid matter that does not fall in separating casing 4 can ceaselessly rotate with air-flow vortex, every rotation once, some solid matter of capital falls under deadweight and action of centrifugal force, goes round and begins again up to whole solid matters and flow separation.
The width that separates casing 4 can be identical with the width A of horizontal sedimentation pipe 2, also can be greater than the width A of horizontal sedimentation pipe 2, but should not be less than the width A of horizontal sedimentation pipe 2.
On the other hand, filter plate 5 tilts to place the effect that improves separative efficiency of having played.The minute solid phase material is at horizontal sedimentation pipe 2 free settling not, there is not the minute solid phase material of abundant sedimentation to enter to separate casing 4 backs very near with the distances of filter plate 5, because the windward side of filter plate 5 is downward inclined-planes, these minute solid phase materials impinge upon can moving downward on the inclined-plane down with the wind of filter plate 5, enter the horizontal gas flow that separates casing 4 once more, reduce the minute solid phase material and passed the possibility of filter plate 5 effusion separation casings 4, thereby improved separative efficiency and precision.
The gas solid separation technical method that Fig. 1 describes promptly can be used for the separation process of gas material, also can be used for dust removal process.
