Description

Technical Field

[0001] The utility model belongs to the technical field of structured packing, in particular to a mesh block structured packing for reducing back mixing. Background Art

[0002] Structured packing is a type of packing that is arranged in a uniform geometric pattern and neatly stacked in a tower. It has been widely used due to its advantages such as large specific surface area, small pressure drop, uniform fluid distribution, and high mass and heat transfer efficiency. The earliest developed was metal structured packing, followed by plastic structured packing, ceramic structured packing, and carbon fiber structured packing.

[0003] Backmixing refers to the phenomenon that part of the fluid flows in the opposite direction and is fully mixed in the cross section of the flow channel due to changes in the fluid flow state or some external action during chemical, physical or biological reactions. This phenomenon will affect the temperature distribution and concentration distribution in the system, as well as the results of the reaction process and other processes. At present, when the mesh structured packing is used to mix steam and liquid, the two liquids are prone to backmixing, resulting in the inability to effectively mix the liquids. For this reason, we have proposed a mesh structured packing that reduces backmixing. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a mesh block structured packing that reduces backmixing, which effectively solves the problems raised in the background technology.

[0009] Preferably, the outer sides of the wave folded plates are all provided with fixed edges, the inner sides of the fixed edges are evenly provided with hook bodies, and the wire mesh folded plates are snap-connected with the hook bodies.

[0010] Preferably, the mesh holes of the wire mesh folding plate are arranged in a square shape, and a hanging edge is arranged on the outer side of the wire mesh folding plate, and the hanging edge is arranged to be snap-connected with the hook body.

[0011] Preferably, the thickness of the wire mesh folding plate is 10-15 MM, and the overall thickness of the wave folding plate is 4-5 CM.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The liquid is guided by the curved sheet so that it flows in an arc shape, so that the liquid and steam can be mixed better. When the mixed liquid of liquid and steam flows, it will be separated when passing through the wire mesh folding plate, and the liquid will be mixed when passing through the curved sheet, thereby effectively reducing the back mixing of the liquid and making the liquid and steam mix better inside the packing body;

[0014] 2.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, by Figure 1-4 A mesh structured packing for reducing back mixing is provided, comprising a packing body 10, wherein the packing body 10 is composed of a wire mesh folding plate 11 and a wave folding plate 12, wherein the wire mesh folding plate 11 is located on the opposite sides of two groups of wave folding plates 12, wherein:

[0025] Square grooves 120 are evenly arranged inside the wave folding plate 12, and a bending piece 121 is arranged inside the square groove 120. The bending piece 121 is curved. When the steam and liquid pass through the packing body 10, the liquid and the steam will be cut by the wire mesh folding plate 11. The wave folding plate 12 guides the liquid to fall, so that the liquid automatically slides through the square groove 120. When the liquid slides down from the inside of the square groove 120, it will be guided by the bending piece 121, so that the liquid flows in an arc shape, so that the liquid and the steam are better mixed, and the mixed liquid of the liquid and the steam will be separated when passing through the wire mesh folding plate 11 when it flows. When passing through the bending piece 121, the liquid will be mixed, thereby effectively reducing the back-mixing phenomenon of the liquid, so that the liquid and steam can be better mixed inside the packing body 10. The wave fold plate 12 is composed of a forward fold plate 122 and a reverse fold plate 123. The forward fold plate 122 and the reverse fold plate 123 are staggered. The wire mesh fold plate 11 is located on the opposite side of the forward fold plate 122 and the reverse fold plate 123. The staggered forward fold plate 122 and the reverse fold plate 123 effectively increase the contact surface of the forward fold plate 122 and the reverse fold plate 123 with the wire mesh fold plate 11, thereby effectively improving the overall strength of the packing body 10 and the service life of the packing body 10. The surface of the wave fold plate 12 The protrusion layer is evenly arranged, and the upper part of the protrusion layer is opened with a circular hole. The protrusion layer can effectively guide the liquid, and the circular hole can make the liquid circulate better, so that the liquid can circulate and mix better, thereby effectively reducing the back-mixing phenomenon. The outer side of the wave folding plate 12 is provided with a fixed edge 124, and the inner side of the fixed edge 124 is evenly provided with a hook body 125. The wire mesh folding plate 11 is clamped with the hook body 125. The mesh of the wire mesh folding plate 11 is arranged in a square shape. The outer side of the wire mesh folding plate 11 is provided with a hanging edge, and the hanging edge is clamped with the hook body 125. The fixed edge 124 can effectively shield the surroundings of the wave folding plate 12, and By providing a hook body 125, the hanging edge of the wire mesh folding plate 11 can be effectively fixed, so that the wire mesh folding plate 11 can be better fixed on the upper part of the wave folding plate 12, and the wire mesh folding plate 11 can be better installed. The square-arranged mesh holes can better divide the liquid. The thickness of the wire mesh folding plate 11 is 10-15MM, and the overall thickness of the wave folding plate 12 is 4-5CM. The surfaces of the wave folding plate 11 and the wire mesh folding plate 12 can assist the wave folding plate 11 and the wire mesh folding plate 12 to better perform anti-corrosion treatment. The thicker wave folding plate 12 and wire mesh folding plate 11 can effectively prevent the wave folding plate 12 and the wire mesh folding plate 11 from deforming, thereby increasing the service life of the device.

[0026] Working principle: When steam and liquid pass through the packing body 10, the wire mesh folding plate 11 will separate the liquid and steam, and the wave folding plate 12 will guide the liquid to fall, so that the liquid can automatically slide through the square groove 120. When the liquid slides down from the inside of the square groove 120, it will be guided by the bending piece 121, so that the liquid flows in an arc shape, so that the liquid and steam can be better mixed. When the mixed liquid of liquid and steam flows, it will be separated when passing through the wire mesh folding plate 11, and the liquid will be mixed when passing through the bending piece 121, thereby effectively reducing the back-mixing phenomenon of the liquid, so that the liquid and steam can be better mixed inside the packing body 10.
