Description

Technical Field

[0001] The utility model relates to the technical field of chemical packing, in particular to a regular chemical packing with high separation efficiency. Background Art

[0002] According to an eccentric guide window type structured packing sheet and packing disclosed in Chinese patent number CN102068956A, the biggest difference between the structured packing and the window guide type structured packing is that the axial direction of the guide window opened has a certain angle with the inclined direction of the corrugation, so that the guide window presents an eccentric structure. The eccentric guide window is opened at the crest or trough of the corrugated structured packing sheet, and the direction is opposite to the direction of the crest or trough. By improving the inclination angle of the guide window so that its axial direction is eccentric, the pressure drop can be effectively reduced, the degree of lateral mixing can be increased, the gas-liquid mass transfer area can be increased, and the degree of liquid film turbulence can be increased. When the liquid flows down along the direction of the corrugation and passes through the position of the eccentric guide window, since the eccentric window is just below the liquid, the performance of the structured packing in the inclined direction of the large corrugation is improved, while ensuring the high efficiency of radial mixing, the ability of lateral mixing on the packing sheet is effectively strengthened, the liquid film is effectively renewed, and the gas-liquid mass transfer rate is increased.

[0003] The above-mentioned comparative documents and prior art have the problem that the entire packing structure is single, the gas-liquid separation efficiency is poor, and the separated liquid is prone to accumulation, which is not conducive to practical use. Utility Model Content

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

[0023] Reference Figure 1-4 A structured chemical packing with high separation efficiency comprises a separation substrate 1 and a separation mesh plate 4. The separation mesh plate 4 is arranged on the top of the separation substrate 1. A first folding plate 5 and a second folding plate 6 are provided between the separation mesh plate 4 and the separation substrate 1. A separation groove 10 is provided at the bending position of the first folding plate 5 and the second folding plate 6. A guide spring 8 is provided inside the separation groove 10, and the bottom end of the guide spring 8 is connected to the top surface of the separation mesh plate 4. A filter mesh sheet 9 is provided on the top of the guide spring 8. A positioning sealing sleeve 2 is provided on the outer surface of the separation mesh plate 4. The whole device is mainly used for gas-liquid separation and filtration inside a chemical tower. The outer edge of the whole packing is sealed by the positioning sealing sleeve 2 to prevent The gas is removed along the side, and the flow direction of the gas is controlled so that the gas flows upward along the bottom of the separation substrate 1, enters the space inside the first folded plate 5 and the second folded plate 6 at the bottom of the separation mesh plate 4, and then continues to flow upward into the position of the separation mesh plate 4, contacts the first folded plate 5 and the second folded plate 6 at the top of the separation mesh plate 4, and finally contacts the filter mesh 9 and flows out. Due to the impact force of the gas, the filter mesh 9 is impacted, causing the guide spring 8 to shake, so that the liquid filtered on the surface of the filter mesh 9 can quickly fall and gather, effectively preventing liquid accumulation, and through the multi-layer channel structure, the basic area with the gas is increased, which is convenient for the rapid separation of gas and liquid.

[0024] To facilitate the flow of gas, the surfaces of the first folding plate 5 and the second folding plate 6 are provided with guide holes 7, and the guide holes 7 are evenly distributed along the vertical direction. The guide holes 7 can be used to guide the flow of gas, prevent gas accumulation, facilitate gas flow, and reduce the impact of gas flow.

[0025] Other limiting structures of the entire device are as follows: the first folded plate 5 and the second folded plate 6 are staggered in a 1:1 manner, the top surface of the first folded plate 5 and the top surface of the second folded plate 6 are coplanar, the bending angle of adjacent sides of the first folded plate 5 is 90 degrees, the bending angle of adjacent sides of the second folded plate 6 is 90 degrees, the side lengths of the first folded plate 5 and the second folded plate 6 are the same, the first folded plate 5 and the second folded plate 6 form a filter layer to increase the contact area with the gas, a multilateral positioning frame 3 is provided on the top surface of the positioning sealing sleeve 2, and the bottom surface of the multilateral positioning frame 3 is against the top surface of the first folded plate 5, the density of the separation mesh plate 4 is twice the density of the separation substrate 1, the cross-section of the top surface of the filter mesh 9 is a circle of exactly the same size, which is convenient for realizing multi-channel filtration, the side surface of the separation substrate 1 is coplanar with the outer wall of the positioning sealing sleeve 2, and the outer wall of the separation mesh plate 4 is coplanar with the inner wall of the positioning sealing sleeve 2. Specific embodiment 2:

[0027] Reference Figure 1-4 In the entire device structure, in addition to the above-mentioned structure, the installation direction of the first folded plate 5 and the second folded plate 6 can also adopt a method of different installation directions for the top and bottom surfaces of the separation mesh plate 4. For example, the filter layer formed by the first folded plate 5 and the second folded plate 6 at the bottom of the separation mesh plate 4 is perpendicular to the installation direction of the top, etc. By changing the installation direction, the contact area is increased and the separation efficiency is improved.

[0028] In actual use, the distribution density of the first folding plate 5 and the second folding plate 6 can be installed in the same density, or in a graded density installation method, such as separating the substrate 1, the first folding plate 5 and the second folding plate 6, the separation mesh plate 4, the first folding plate 5 and the second folding plate 6, and the filter mesh 9 from bottom to top, the density increases in sequence.
