Abstract
Description
Technical Field
[0001] This utility model relates to the field of intelligent drug storage and retrieval cabinet technology, and in particular to a washing tower demisting device. Background Technology
[0002] In industrial production processes, demisters are typically used to remove liquid droplets entrained in gases to reduce the contamination and corrosion of airflow channels and subsequent equipment, or to prevent the direct emission of gases containing mist droplets from polluting the atmosphere. Existing scrubbing towers typically use baffle-type demisters for gas-liquid separation. Application No. 202321105031.4 discloses a demister for a spray tower, which removes droplets by having multiple baffles stacked side by side impact the inner wall of an S-shaped channel. However, this structure can only remove larger droplets. For smaller droplets, the baffle demister, which relies solely on inertial deflection, cannot effectively capture them. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a scrubbing tower demisting device that can capture tiny droplets and improve demisting ability.
[0004] The objective of this utility model is achieved through the following technical solution: a scrubbing tower demisting device, comprising a cylindrical body, multiple first baffles, and multiple second baffles. The first baffles and second baffles have the same bending shape and are evenly spaced within the cylindrical body. The first baffles and second baffles are staggered vertically, and multiple rhomboid channels are formed between adjacent first baffles and second baffles. The rhomboid channels are distributed in at least two layers vertically within the cylindrical body and are interconnected vertically. Each rhomboid channel is provided with a diverter plate, the cross-section of which is rhomboid, and the diverter plate is fixedly connected to the center of the rhomboid channel.
[0005] Furthermore, multiple limiting strips are provided on both the upper and lower surfaces of the cylinder. The limiting strips are perpendicular to the first and second baffle plates. Multiple grooves are provided on the limiting strips, and the ends of the first and second baffle plates are inserted into the grooves. Multiple connecting rods are provided between the upper and lower distributed flow dividers, and the connecting rods are respectively fixedly connected to the middle of the flow divider. Multiple screws are provided on the limiting strips, and the screws pass through the limiting strips to fix the flow dividers. The two ends of the limiting strips are respectively fixedly connected to the cylinder.
[0006] Furthermore, the flow divider is provided with a plurality of third baffles, which are located on the lower surface of the flow divider and are vertically arranged. The upper end of the third baffle is fixedly connected to the lower surface of the flow divider.
[0007] Furthermore, the distance between the bottom end of the first baffle plate and the bottom end of the second baffle plate is the sum of the distance between the bottom end of the first baffle plate and the bottom end of the diverter plate, and the distance between the bottom end of the second baffle plate and the bottom end of the diverter plate.
[0008] This invention has the following advantages: By setting a flow divider plate within the rhomboid channel formed by the first and second baffle plates, two opposing airflow channels are created, enabling the continuous aggregation of small droplets into larger droplets for collection, thus greatly improving gas-liquid separation capability; the third baffle plate on the flow divider plate increases the droplet collision area, further enhancing droplet collection capability; the limiting clip is inserted into the first and second baffle plates, and the limiting clip is screwed to the flow divider plate, facilitating later disassembly and maintenance and improving maintenance efficiency; limiting the width of the bottom flat plate of the first and second baffle plates ensures that the flow rate of each rhomboid channel is the same, improving the uniformity of processing capacity.

[0014] like Figure 1 As shown, a scrubbing tower demisting device includes a cylindrical body 1, multiple first baffles 2, and multiple second baffles 3. The first baffles 2 and second baffles 3 have the same bending shape, both being W-shaped bends. The first baffles 2 and second baffles 3 are arranged side-by-side at even intervals within the cylindrical body 1. The first baffles 2 and second baffles 3 are vertically staggered, meaning their bending points are opposite or opposite to each other. Multiple rhomboid channels are formed between adjacent first baffles 2 and second baffles 3, and are distributed vertically within the cylindrical body 1 as two complete rhomboid channels and half-rhomboid channels. The rhomboid channels are interconnected vertically to form a gourd shape. Each rhomboid channel contains one diverter plate 4. In a complete rhomboid channel, the diverter plates 4 have a rhomboid cross-section, while in an incomplete rhomboid channel, the diverter plates 4 have a triangular cross-section. Multiple limiting strips 5 are installed on both the upper and lower surfaces of the cylinder 1. The limiting strips 5 are parallel to each other and perpendicular to the first baffle plate 2 and the second baffle plate 3. Multiple inclined grooves 6 are formed on the limiting strips 5, and the ends of the first baffle plate 2 and the second baffle plate 3 are inserted into the grooves 6. The diverter plates 4 are distributed vertically. Multiple connecting rods 7 are installed between the flow dividers 4, spaced apart along the middle of the flow divider 4. The upper and lower ends of the connecting rods 7 are vertically welded to the middle sections of the upper and lower flow dividers 4, respectively. The connecting rods 7 suspend or support the flow dividers 4 within the diamond-shaped channel. Multiple through holes are provided in the limiting strip 5, and screws 8 are installed in each through hole. The screws 8 pass through the limiting strip 5 and are threadedly connected to the flow divider 4 and the cylinder 1. Multiple third baffles 9 are installed on the flow divider 4. The third baffles 9 are flat plate structures located on the two lower surfaces of the flow divider 4, and are vertically arranged. The lower surface of the flow divider plate 4 is welded to the upper end of plate 9. The width of the plate connected to the bottom end of the first baffle plate 2 and the width of the plate connected to the bottom end of the second baffle plate 3 are both smaller than the width above. The width of the plate connected to the bottom end of the first baffle plate 2 and the width of the plate connected to the bottom end of the second baffle plate 3 are cut to meet the following conditions: the distance between the bottom end of the first baffle plate 2 and the bottom end of the second baffle plate 3 is the sum of the distance between the bottom end of the first baffle plate 2 and the bottom end of the triangular flow divider plate 4 and the distance between the bottom end of the second baffle plate 3 and the bottom end of the triangular flow divider plate 4, that is, the bottom air inlet area of each diamond channel is equal.
[0015] The working principle of this invention is as follows: A flow divider is installed within the rhomboid channel formed by the first and second baffles. The flow divider further divides the original single baffle channel into two smaller channels, allowing gas and liquid to flow. The gas and liquid enter from the bottom of the smaller channels and collide with the first and second baffles. Larger droplets are blocked and collected, while smaller droplets continue to move upward. Due to the converging intersection point between the two smaller channels, the two airflows collide. At this point, under the action of surface tension, the smaller droplets collide to form larger droplets. As the larger droplets continue to flow upward, they continue to collide with the inner wall and are collected. The entire process achieves the function of continuously converging small droplets into larger droplets and collecting them. This design significantly improves gas-liquid separation capabilities. After the two gas streams converge at the point of intersection, the droplet flow becomes somewhat chaotic. A third baffle plate on the lower surface of the flow divider increases the impact area and improves droplet collection. The limiting strip is inserted into the first and second baffle plates, and screwed into the flow divider plate; both connection methods facilitate subsequent disassembly, cleaning, and maintenance. Limiting the width of the bottom plates of the first and second baffle plates ensures that the gas and liquid flow rates into each diamond-shaped channel are identical, preventing excessive pressure in some diamond-shaped channels and thus avoiding localized blockages. This improves the homogeneity of gas-liquid separation and extends service life.
[0016] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
