Description

Technical Field

[0001] This utility model relates to the field of metallurgical production technology, and in particular to an acid mist adsorption tower. Background Technology

[0002] In the metallurgical industry, wet analysis remains a widely used method for elemental composition detection of media required in steel plant production processes, such as raw materials, continuously cast billets, boiler water, emulsions, and acid regeneration solutions. Chemical analysis inevitably involves the use of large quantities of concentrated hydrochloric acid, concentrated sulfuric acid, and other chemical reagents, generating significant amounts of acid mist during solution preparation. To meet environmental protection and energy conservation requirements, acid mist adsorption towers using alkali absorption are increasingly being used in steel plants as a highly efficient method for treating acid mist.

[0003] Since acid mist adsorption towers are mostly made of polypropylene, the bottom of the cylindrical body is generally welded to the side, and currently, acid mist adsorption towers are mainly placed directly on the ground. However, when the welds become less tight due to prolonged use and equipment aging, leaks are very likely to occur. The solution at the bottom of the tower is mostly a strongly alkaline sodium hydroxide solution. If inspections are not timely, excessive leakage of this strong alkali can occur, polluting the surrounding environment and leading to material waste. Furthermore, because sodium hydroxide solution is highly corrosive, it can also pose a significant health hazard to workers. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an acid mist adsorption tower, comprising a tower body and a leakage monitoring mechanism. The leakage monitoring mechanism includes a liquid collection tray and a liquid storage tank. The liquid collection tray is arranged circumferentially along the bottom of the tower body, and the outer diameter of the liquid collection tray is larger than the outer diameter of the tower body. A leakage outlet is provided on the liquid collection tray, and a leakage inlet is provided on the leakage storage tank. The leakage inlet is connected to the leakage outlet.

[0005] Furthermore, the liquid collection tray is divided into multiple liquid collection areas, which are distributed sequentially along the circumference of the tower body. Each liquid collection area is provided with a leakage outlet. There are multiple leakage storage tanks, and the number of leakage storage tanks is the same as the number of liquid collection areas and they are set up one-to-one.

[0006] Furthermore, the bottom of each of the liquid accumulation areas has a slope, and the leakage outlet is located at the bottom of the slope of the liquid accumulation area.

[0007] Furthermore, adjacent liquid accumulation areas are separated by partitions, each of which is disposed on the liquid accumulation tray.

[0008] Furthermore, the height of each partition near the tower body is higher than the height of the connection node between the tower body and the tower bottom.

[0009] Furthermore, the leakage monitoring mechanism also includes a monitoring unit for leakage monitoring, which is installed on the leakage storage tank.

[0010] Furthermore, the monitoring unit is a pH meter or a level gauge.

[0011] Furthermore, the leakage inlet is connected to the leakage outlet via a guide pipe.

[0012] Furthermore, a check valve is provided on the flow guide pipe.

[0013] Furthermore, the leakage monitoring mechanism also includes a cover plate, which is disposed on the liquid collection tray.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1) The acid mist adsorption tower provided by this utility model is equipped with a leakage monitoring mechanism at the bottom of the tower. The liquid collection tray is set around the bottom of the tower body, which can collect the leakage on the tower body and concentrate it in the leakage storage tank for storage and detection to determine whether there is leakage.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this utility model, the terms "first" and "second" are used merely for descriptive distinction and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] As per the instruction manual Figure 1 and 2As shown, this utility model provides an acid mist adsorption tower, including a tower body 1 and a leakage monitoring mechanism. The leakage monitoring mechanism includes a liquid collection tray 2 and a liquid storage tank 3. The liquid collection tray 2 is arranged circumferentially along the bottom of the tower body 1. The outer diameter of the liquid collection tray 2 is larger than the outer diameter of the tower body 1. A leakage outlet 21 is provided on the liquid collection tray 2. A leakage inlet 31 is provided on the leakage storage tank 3. The leakage outlet 21 is higher than the leakage inlet 31. The leakage inlet 31 is connected to the leakage outlet 21.

[0027] Specifically, the acid mist adsorption tower is used for acid mist adsorption. The solution inside the tower body 1 is mostly alkaline, so the leaked liquid is also mostly alkaline. Leakage can be determined by monitoring the pH value or liquid level of the leaked liquid. For example, a liquid level gauge can be installed on the leaked liquid storage tank 3, and the presence of a leak can be determined by the liquid level in the leaked liquid storage tank 3. The tower body 1 includes a tower body and a tower bottom, which are preferably made of polypropylene. The tower body and tower bottom are welded together. Due to prolonged use, there is a risk of leakage at the connection point between the tower body and the tower bottom. A liquid collection tray 2 is installed circumferentially at the bottom of the tower body 1. The outer diameter of the liquid collection tray 2 is larger than the outer diameter of the tower body 1, allowing leaked liquid from all around the tower body 1 to fall into the liquid collection tray 2, preventing overflow. There are two ways to set up the liquid collection tray 2. First, the liquid collection tray 2 and the tower body 1 are separate structures, with the tower body 1 mounted on the liquid collection tray 2, which collects the leakage around the tower body 1. Second, the liquid collection tray 2 and the tower bottom are an integrated structure, with the liquid collection tray 2 distributed circumferentially along the tower bottom, and its outer diameter larger than that of the tower bottom, allowing it to collect the leakage around the tower body 1. The leakage in the liquid collection tray 2 enters the leakage storage tank 3 through the leakage outlet 21. This serves two purposes: firstly, it collects the leakage, preventing it from flowing directly to the ground and harming the environment and human health; secondly, it returns the leakage in the storage tank to the acid mist adsorption tower for reuse, reducing wastewater treatment costs; and thirdly, it detects any leakage, providing timely feedback and warnings to remind staff to take appropriate preventative measures to avoid greater losses.

[0028] To optimize the implementation method and facilitate leakage monitoring, the leakage monitoring mechanism further includes a monitoring unit 4 for leakage monitoring, which is installed on the leakage storage tank 3.

[0029] In an optimized implementation, the monitoring unit 4 is a pH meter or a level gauge, which determines whether there is a leak by monitoring the pH value or level change in the leakage storage tank 3. In this embodiment, the leak in the tower body 1 is mostly alkaline solution, so the presence of a leak can be determined by monitoring the pH value. The pH meter is preferably an online pH meter. A certain amount of purified water is pre-filled into the leakage storage tank 3 until it submerges the pH meter probe. The opening height of the leakage inlet 31 should be higher than the purified water level to prevent backflow of liquid into the leakage storage tank 3. One end of the online pH meter is connected to the leakage storage tank 3, and the other end transmits a signal to the control room, allowing staff to monitor pH changes in real time and determine whether and to what extent a leak has occurred, facilitating timely inspection and maintenance.

[0030] Preferably, there is a height difference between the accumulating tray 2 and the leaking storage tank 3, so that the leaked liquid can flow from the accumulating tray 2 to the leaking storage tank 3 by gravity. The accumulating tray 2 can be raised accordingly, or the leaking storage tank 3 can be pre-buried underground to maintain the height difference between the accumulating tray 2 and the leaking storage tank 3. In this embodiment, the accumulating tray 2 is mounted on the equipment foundation 6, which is a concrete pier used to support the tower body 1. The diameter of the equipment foundation 6 is larger than the outer diameter of the tower body 1, and the outer diameter of the accumulating tray 2 is larger than the diameter of the equipment foundation 6.

[0031] In this embodiment, the tower body 1 has a diameter of approximately 1500 mm, the equipment foundation 6 has a width of 1700 mm, the liquid collection tray 2 has a diameter of approximately 1800 mm, and the liquid outlet 21 on the liquid collection tray 2 is located on the outside of the equipment foundation 6.

[0032] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3 As shown, due to the large diameter of the tower body 1, in order to quickly respond to leaks and locate and repair the leak, the liquid collection tray 2 is divided into multiple liquid collection areas. These areas are distributed sequentially along the circumference of the tower body 1, and each area has a leak outlet 21. Multiple leak storage tanks 3 are provided, with the number of tanks matching the number of liquid collection areas. Each tank 3 is equipped with a monitoring unit 4, which further divides the liquid collection tray 2 into multiple areas. Even small leaks can be quickly detected, allowing for rapid response. By numbering each liquid collection area and the monitoring unit 4, the corresponding leak area on the tower body 1 can be identified, enabling rapid location of the leak for timely maintenance or repair, thus preventing greater losses.

[0033] In the optimized implementation, the bottom of each liquid accumulation area has a slope, and the leakage outlet 21 is opened at the bottom of the slope of the liquid accumulation area, so that the leakage from the liquid accumulation area can be collected towards the leakage outlet 21 and flow into the leakage storage tank 3.

[0034] In an optimized implementation, adjacent liquid accumulation areas are separated by partitions 22. That is, multiple partitions 22 are provided on the liquid accumulation tray 2, and the multiple partitions 22 are arranged sequentially along the circumference of the tower body 1. The liquid accumulation tray 2 is divided into multiple liquid accumulation areas by the multiple partitions 22.

[0035] In an optimized implementation, the height of the side of each partition 22 closest to the tower body 1 is higher than the height of the connection node between the tower body and the tower bottom of the tower body 1, so that the leakage at the connection node between the tower body and the tower bottom flows into their respective corresponding liquid accumulation areas.

[0036] In an optimized implementation, the bottom of each partition 22 is connected to the liquid collection tray 2, and the partition 22 and the liquid collection tray 2 are an integral structure. The side of each partition 22 facing the tower body 1 is connected to the tower body 1, which can improve the strength of the connection node between the tower body and the tower bottom.

[0037] In an optimized implementation, the leakage storage tank 3 is located on one side of the liquid accumulation pan 2, and the leakage inlet 31 is connected to the leakage outlet 21 through the guide pipe 5. The guide pipe 5 is inclined downward, and one end of the leakage inlet is lower than one end of the leakage outlet.

[0038] Of course, the leakage storage tank 3 can be set below the liquid accumulation pan 2, and the leakage inlet 31 can be opened on the top of the leakage storage tank 3. The top of the leakage storage tank 3 is in contact with the bottom of the liquid accumulation pan 2, and the leakage inlet 31 is aligned with the leakage outlet 21.

[0039] In an optimized implementation, a check valve 51 is provided on the guide pipe 5 to prevent liquid in the leakage storage tank 3 from flowing back into the liquid accumulation pan 2.

[0040] As one specific implementation, to further improve the response rate of leakage detection, a liquid collection tank 23 is provided on the liquid collection tray 2. The liquid collection tank 23 is arranged circumferentially around the tower body 1 and is adjacent to the tower body 1. The liquid collection tank 23 is connected to the leakage outlet 21 through a chute 24. The leakage from the tower body 1 flows into the liquid collection tank 23 and then flows to the leakage outlet 21 through the chute 24. The liquid collection tank 23 has a small volume, so a small amount of leakage can be concentrated and flow to the leakage outlet 21, which can improve the leakage detection response rate. The liquid collection tank 23 is divided into multiple liquid collection tank segments by a partition 22. Each liquid collection tank segment is connected to the corresponding leakage outlet 21 through a chute 24, so that the leakage enters the corresponding leakage storage tank 3 for storage and detection.

[0041] Preferably, the bottom of the collection tank 23 has a certain slope, and the chute 24 is connected to the bottom of the slope of the collection tank 23. Specifically, the bottom of each collection tank section has a certain slope. This can be achieved by having a continuous slope from one end of the collection tank section to the other, allowing leaked liquid flowing into the collection tank section to flow down the slope to the bottom, with the chute connected to the bottom of the slope. Alternatively, the middle section of the collection tank section can have a certain slope from both ends, with the middle section located at the bottom of the slope. This allows leaked liquid in the collection tank section to be concentrated in the middle section via the slope, with the chute connected to the middle section of the collection tank section.

[0042] In an optimized implementation, the leakage monitoring mechanism further includes a cover plate, which is placed over the liquid collection tray. The cover plate can be a separate structure, positioned on the liquid collection tray to form a leakage containment area. Alternatively, the cover plate can be a single piece, with clearance holes through which the tower body passes. The cover plate on the liquid collection tray 2 protects against leakage and prevents damage due to operator error.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
