Description

Technical Field

[0001] The invention relates to a filler, in particular to a multi-bend-rod hollow ball filler. Background Art

[0002] Multifaceted hollow balls are widely used in domestic power, chemical, papermaking and other industries, and are used in equipment for removing chlorine, oxygen and carbon dioxide. The filler has the characteristics of large porosity, not easy to be blocked, large flux and small resistance. Since the gaps of this filler can have a high amount of liquid stagnation, the liquid in the tower can stay for a long time, thereby increasing the contact time between gas and liquid and improving efficiency.

[0003] In the prior art, fillers are filled into the tower in a stacked state, and adjacent fillers are inserted into each other, resulting in defects such as embedding and biting, which leads to a small gas-liquid contact area in the tower, affecting the heat and mass transfer effect of the tower and making it inconvenient to use. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a multi-bend-rod hollow ball filler which can avoid mutual biting and increase the liquid residence time.

[0005] A multi-bend rod hollow ball packing comprises a center tube and a bent rod. The center tube is composed of an upper ring, a middle ring, a lower ring and a connecting rod from top to bottom. The upper ring and the middle ring and the middle ring and the lower ring are connected up and down by vertical connecting rods respectively. A vertical center column is arranged at the center of the center tube. One end of the straight rod is connected to the center column, and the other end of the straight rod is connected to the inner wall of the center tube. The straight rods of the upper and lower layers are arranged alternately, and the straight rods of the same layer are evenly distributed around the center column. The bent rods are arranged around the center tube, and the bent rods include an upper bent rod, a lower bent rod and a middle bent rod. The bent rods bend outward from the center tube. One end of the upper curved rod is fixed on the outer wall of the upper ring, the other end of the upper curved rod is fixed on the outer wall of the middle ring, the upper curved rods are evenly distributed around the upper ring and the middle ring, the middle part of the upper curved rod is fixed to the upper reinforcement ring, one end of the lower curved rod is fixed on the outer wall of the lower ring, the other end of the lower curved rod is fixed on the outer wall of the middle ring, the lower curved rods are evenly distributed around the lower ring and the middle ring, the middle part of the lower curved rod is fixed to the lower reinforcement ring, one end of the middle curved rod is fixed on the outer wall of the upper reinforcement ring, and the other end of the middle curved rod is fixed on the outer wall of the lower reinforcement ring. The middle part of the middle curved rod is fixed on the middle reinforcement ring, and the upper reinforcement ring, the middle reinforcement ring and the lower reinforcement ring are arranged horizontally.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: the upper reinforcement ring and the lower reinforcement ring in the present invention can not only strengthen the connection between the upper curved rod, the lower curved rod and the middle curved rod and increase the mechanical strength of the curved rod to avoid damage to the curved rod, but also prevent the curved rods of adjacent packings from being embedded in the packing to avoid the phenomenon of mutual embedding and biting; the straight rods arranged in the central tube can further increase the liquid retention amount and increase the residence time.

[0011] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 —4.

[0012] A multi-bend-rod hollow ball filler comprises a central tube 100 and a bent rod 200.

[0013] The central tube 100 is composed of an upper ring 101, a middle ring 102, a lower ring 103 and a connecting rod 104 from top to bottom. The upper ring 101 and the middle ring 102 and the middle ring 102 and the lower ring 103 are connected up and down by vertical connecting rods 104, respectively. A vertical central column 105 is arranged at the center of the central tube 100. One end of a straight rod 106 is connected to the central column 105, and the other end of the straight rod 106 is connected to the inner wall of the central tube 100. The straight rods 106 of the upper and lower layers are arranged in a staggered manner, and the straight rods 106 of the same layer are evenly distributed around the central column 105. The straight rods 106 arranged in the central tube 100 can further increase the liquid retention amount and increase the contact residence time of gas and liquid.

[0014] The above-mentioned curved rods 200 are arranged around the central tube 100. The curved rods 200 include an upper curved rod 201, a lower curved rod 202 and a middle curved rod 203. The curved rods 200 are bent outward from the central tube 100.

[0015] One end of the upper curved rod 201 is fixed on the outer wall of the upper ring 101, the other end of the upper curved rod 201 is fixed on the outer wall of the middle ring 102, the upper curved rod 201 is evenly distributed around the upper ring 101 and the middle ring 102, the middle part of the upper curved rod 201 is fixed to the upper reinforcement ring 204, one end of the lower curved rod 202 is fixed on the outer wall of the lower ring 103, the other end of the lower curved rod 202 is fixed on the outer wall of the middle ring 102, the lower curved rod 202 is evenly distributed around the lower ring 103 and the middle ring 102, the lower curved rod 202 is fixed to the lower reinforcement ring 205, one end of the middle curved rod 203 is fixed on the outer wall of the upper reinforcement ring 204, and the other end of the middle curved rod 203 is fixed on the outer wall of the lower reinforcement ring 205. The middle part of the middle curved rod 203 is fixed on the middle reinforcement ring 206, and the upper reinforcement ring 204, the middle reinforcement ring 206 and the lower reinforcement ring 205 are arranged horizontally.

[0016] The upper reinforcing ring 204 and the lower reinforcing ring 205 can not only strengthen the connection between the upper curved rod 201, the lower curved rod 202 and the middle curved rod 203 to avoid damage to the curved rod 200, but also prevent the curved rod 200 of the adjacent packing from being embedded in the packing to avoid mutual embedding and biting.

[0017] The present invention can be applied to the water treatment industry. When in use, the filler of the present invention can be directly put into the equipment, and the fillers are stacked on each other in the equipment. When the upper curved rod 201, the middle curved rod 203 and the lower curved rod 202 between adjacent fillers cross each other and are close together, the curved rod 200 cannot be inserted into the adjacent fillers and will not bite each other. Even when the curved rods 200 of adjacent fillers are parallel and close together, there are obstacles such as the upper reinforcement ring 204, the lower reinforcement ring 205 and the middle reinforcement ring 206, and the curved rod 200 cannot be inserted into the adjacent fillers and will not bite each other. In this way, there are only point contacts between adjacent fillers, which increases the gaps between the filler particles and reduces the resistance of the gas passing through the filler layer. Moreover, these contact points can also be the convergence and dispersion points of the liquid flowing along the surface of the filler, thereby promoting the surface newness of the liquid film and facilitating the improvement of the mass transfer efficiency of the filler.

[0018] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
