Technical Field

[0001] The utility model relates to the technical field of chemical fillings, in particular to a high-efficiency structured chemical tower filling. Background Art

[0002] Chemical packing is the basic component of gas-liquid contact in packed towers. It is widely used in many industries and has excellent acid and heat resistance. It can withstand the corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid. It can be used in various high and low occasions. The quality of its performance is the main factor that determines the operating performance of the packed tower. The packing inside the chemical tower is generally used for gas-liquid separation, defoaming and other processes.

[0003] In the prior art, the packing used inside chemical towers generally adopts a single packing to set up multiple groups of distribution structures, and the functional structure is single. Since the single packing has the same processing efficiency at different positions when the gas passes through, it cannot achieve the effect of diverting and guiding the gas passing through. The functional structure is insufficient and is not conducive to actual use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of single filler and insufficient functional structure in chemical towers in the prior art, and to propose a high-efficiency structured chemical tower filler.

[0006] Preferably, the circular filler and the filter mesh layer are symmetrically distributed along the horizontal center line of the front side of the I-shaped filler, and the strip mesh layer is gap-matched with the filler installation groove.

[0007] Preferably, the angle between the line connecting the two ends of the top surface of the filter mesh layer and the bottom surface is 45 degrees, and the filter mesh layer is an arc surface with the surface bent toward the direction where the circular filler is located.

[0008] Preferably, the density of the filter mesh layer is twice the density of the strip mesh layer, and the end of the strip mesh layer is coplanar with the side surface of the I-shaped filler.

[0009] Preferably, the top surface cross-sections of the filter mesh layer, the circular filler, the I-shaped filler and the strip mesh layer are all circles of the same size.

[0010] Preferably, the density of the circular filler is twice that of the I-shaped filler, and the thickness of the I-shaped filler is four times that of the circular filler.

[0011] Preferably, the filter mesh layer, circular filler, I-shaped filler and strip mesh layer are installed as a group, and the multiple groups are installed symmetrically and staggered.

[0012] Beneficial effects

[0013] In the utility model, filter mesh layers and circular fillers are symmetrically distributed along the I-shaped fillers, and strip mesh layers are staggered inside the I-shaped fillers to form the entire filler structure, so that the entire filler structure is composed of multiple groups of density structures, which can realize the separation and treatment of different levels of passing gas.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0021] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

[0023] Reference Figure 1-4A high-efficiency structured chemical tower packing comprises a circular packing 2 and a filter mesh layer 1. The filter mesh layer 1 is provided on the top surface of the circular packing 2, and an I-shaped packing 3 is provided on the bottom surface of the circular packing 2. The I-shaped packing 3 has packing installation grooves 5 evenly and equidistantly distributed in straight lines, and the packing installation grooves 5 penetrate the side surfaces of the I-shaped packing 3. A strip mesh layer 4 is provided inside the packing installation grooves 5. The bottom surface of the I-shaped packing 3 is sequentially provided with a circular packing 2 and a filter mesh layer 1. The filter mesh layer 1 and the circular packing 2 are symmetrically distributed along the I-shaped packing 3, and the strip mesh layers 4 are staggered inside the I-shaped packing 3 to form the entire packing structure, so that the entire packing structure is composed of multiple groups of density structures, thereby realizing separation and treatment of different levels of passing gas.

[0024] In order to increase the degree of coordination of the entire device, the circular filler 2 and the filter mesh layer 1 are symmetrically distributed along the horizontal center line of the front of the I-shaped filler 3, and the strip mesh layer 4 is gap-matched with the filler mounting groove 5. Through the coordination of the strip mesh layer 4 and the filler mounting groove 5, the regular structure of the entire I-shaped filler 3 is increased, so that when the gas passes through the bottom of the I-shaped filler 3, it can simultaneously pass through the strip mesh layer 4 and the I-shaped filler 3 for gas-liquid separation. Due to the different separation efficiencies of the I-shaped filler 3 and the strip mesh layer 4, the separated gases appear in a sequence when discharged through the top of the I-shaped filler 3, thereby achieving the effect of diversion and diversion, and effectively preventing gas accumulation.

[0025] In order to increase the contact range between the entire device and the gas, the angle between the line between the two ends of the top surface of the filter mesh layer 1 and the bottom surface is set to 45 degrees, and the filter mesh layer 1 is an arc surface with the surface bent in the direction of the circular filler 2. At the same time, an arc-shaped filter mesh layer 1 structure is set to increase the vertical coverage range when the installation area is inconvenient, thereby increasing the contact cotton knots with the gas, having strong structural strength, being convenient for use in chemical gas-liquid separation, and improving the gas-liquid separation efficiency.

[0026] Other limiting structures of the entire device are that the density of the filter mesh layer 1 is twice the density of the strip mesh layer 4, the end of the strip mesh layer 4 is coplanar with the side of the I-shaped filler 3, the cross-sections of the top surfaces of the filter mesh layer 1, the circular filler 2, the I-shaped filler 3 and the strip mesh layer 4 are all circles of the same size, the density of the circular filler 2 is twice the density of the I-shaped filler 3, and the thickness of the I-shaped filler 3 is 4 times the thickness of the circular filler 2. By setting different density structures, the gas can be separated to different degrees, the richness during separation is increased, the gas dispersion and diversion are convenient, the gas residence time in the tower is increased, and the separation efficiency is improved. Specific embodiment two:

[0028] Reference Figure 1-4When the entire device is installed, the filter mesh layer 1, circular filler 2, I-shaped filler 3 and strip mesh layer 4 are installed as a group, and multiple groups of installation centers are symmetrically staggered. Multiple groups of structures can be set when the entire component structure is installed in the tower. Compared with the traditional single filler structure, the structure of the entire filler component is richer, the gas processing efficiency is higher, and it is convenient for gas-liquid separation. At the same time, the filter mesh layer 1 set on the top and bottom surfaces can achieve the effect of defoaming. Specific embodiment three:

[0030] Reference Figure 1-4 During installation, the filter mesh layer 1, the circular filler 2 and the I-shaped filler 3 are generally connected by welding, and the strip mesh layer 4 and the I-shaped filler 5 are directly welded. The specific connection structure is combined in combination with actual usage while ensuring the integration of the entire filler structure. For example, it can be set as a detachable structure for successive installation to facilitate replacement of each layer.

[0031] In summary:

[0032] The filter mesh layer 1 and the circular filler 2 are symmetrically distributed along the I-shaped filler 3, and the strip mesh layer 4 is staggered inside the I-shaped filler 3 to form the entire filler structure, so that the entire filler structure is composed of multiple groups of density structures, which can realize the separation and treatment of different levels of the passing gas. At the same time, the arc-shaped filter mesh layer 1 structure is set to increase the vertical coverage range when the installation area is inconvenient, thereby increasing the contact cotton knots with the gas, having strong structure, being convenient for use in chemical gas-liquid separation, and improving the gas-liquid separation efficiency.
