[ example ]
As shown in fig. 1, a gas distribution filler is provided with 6 layers of fillers from bottom to top, namely a first layer of filler 101, a second layer of filler 102, a third layer of filler 103, a fourth layer of filler 104, a fifth layer of filler 105 and a sixth layer of filler 106, each layer of filler comprising a plurality of filler blocks.
As shown in fig. 2 and 3, the filler block comprises a cylinder 1, a first folded plate 2, a second folded plate 3, a straight plate 4 and a circular ring 5. The cylinder 1 is fixedly connected with the left end of the straight plate 4, and the circular ring 5 is fixedly connected with the right end of the straight plate 4. The outer diameter of the cylinder 1 is smaller than the inner diameter of the circular ring 5, a gap is formed in the outer side of the circular ring 5, and the width of the gap is larger than that of the straight plate 4.
When in installation, two adjacent fillers in the same layer are placed into the circular ring 5 of the other adjacent filler block through the cylinder 1 at the end part of one filler, and the two fillers are connected. The installation and the disassembly are convenient and quick.
The four straight plates 4 are parallel to each other, at equal intervals, which are equal to the length of the folded plate. The first folding plates 2 and the second folding plates 3 are identical in shape and size, the four first folding plates 2 and the four second folding plates 3 are identical in inclination angle, opposite in direction and symmetrically staggered between two adjacent straight plates 4, and the included angles of the first folding plates 2 and the second folding plates 3 and the vertical surfaces are acute angles. The first folded plate 2 and the second folded plate 3 form a V shape with an opening at the lower end, the distance between the upper edge of the first folded plate 2 and the upper edge of the second folded plate 3 is larger, a large opening is formed, the distance between the lower edge of the first folded plate 2 and the lower edge of the second folded plate 3 is smaller, a small opening is formed, and the first folded plate 2 and the second folded plate 3 form openings with staggered upper and lower sizes.
As shown in fig. 4 and 5, the first folded plate 2, the second folded plate 3 and the straight plate 4 are uniformly provided with through holes, and can be provided with holes with various shapes, such as a circle, an ellipse, a rectangle and the like.
The filler block is made of plastic materials and is integrally injection molded. The gas distribution filler is made of plastic material and has low price. The packing is installed through the manhole, and the shortest edge of the packing block is smaller than the diameter of the manhole, so that each packing block can be installed through the manhole.
As shown in fig. 1-5, when the gas distribution packing is installed, a first layer of packing 101 is placed into a circular ring 5 of adjacent gas distribution packing along the length direction of a packing end cylinder 1, two packing ends are connected, the two packing ends are connected in sequence, and packing is cut at the end part of a tower and is matched with the inner wall of the tower; the length directions of the adjacent fillers are parallel and are tightly adhered, and the whole tower body is fully covered.
The second layer of packing 102 is mounted in the same length direction as the first layer of packing 101, but the packing is turned 180 degrees, i.e. the large openings are opposite to the large openings and the small openings are opposite to the small openings. The third layer of packing 103 corresponds to the first layer of packing 101, the fourth layer of packing 104 corresponds to the second layer of packing 102, and so on. And after the final filling is installed, a pulse structure from bottom to top is formed.
After the final filling is installed, a pulse structure from bottom to top is formed, the pulse structure is provided with a plurality of contraction sections and expansion sections, and gas and liquid repeatedly form expansion and contraction flows in a flow channel flowing in opposite directions to carry out mass transfer.
In the contraction section, the flow velocity of the fluid is large, so that mass transfer is enhanced; in the expansion section, the flow speed is slowed down, and the phenomena of gas-liquid two-phase separation and convection are generated. When the whole gas feed gas passes through the filler, the gas speed and the resistance are different when passing through each contraction section or expansion section due to uneven gas distribution. When the gas speed of one contraction section or expansion section is high, the gas resistance is increased, the flow speed is reduced, and finally, the gas with different flow speeds passes through the gas distribution filling materials with the multi-pulse structure, so that the gas flow speeds tend to be similar, and the trend that the gas flows upwards uniformly in the tower is formed.
At the same time, through the openings of the first folding plate 2, the second folding plate 3 and the straight plate 4, the gas flows into the space with small resistance of the partition wall when the resistance is large.
Finally, the function of uniform gas distribution is realized, meanwhile, the mass transfer function is realized, and the tower operation requirement is met due to the large open pore and difficult blockage. Meanwhile, the method has the advantages of small pressure drop, high separation efficiency, high operation elasticity and strong adaptability.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
