Description

Technical Field

[0001] The utility model relates to the technical field of acid mist treatment, in particular to a multi-stage acid mist treatment device. Background Art

[0002] In the steel production process, the cleaning step is essential. It aims to remove impurities on the surface of steel and improve the quality of steel. However, this process is often accompanied by a serious environmental problem - the generation of acid mist. Acid mist, that is, visible smoke formed by sulfuric acid particles, is usually caused by the combustion of fossil fuels or the exhaust gas containing sulfur oxides produced during the mineral smelting process. These exhaust gases are discharged into the atmosphere, which not only pollutes the environment, but also poses a threat to the health of surrounding residents.

[0003] Acid mist has many potential hazards to the human body. First, sulfuric acid droplets can irritate the human respiratory tract, causing symptoms such as coughing and sore throat. In severe cases, it may lead to respiratory diseases. Secondly, long-term exposure to acid mist environment may also cause irritation to the skin and eyes, and even increase the risk of skin cancer. Therefore, the control and treatment of acid mist is one of the important tasks of environmental protection.

[0004] At present, the treatment of acid mist usually relies on an acid mist spray tower, which absorbs sulfuric acid in the acid mist by spraying an alkaline solution (such as limestone slurry), thereby reducing the emission of acidic gases. However, the existing acid mist spray tower is usually only one, which makes it inefficient in treating acid mist. One tower may not be able to completely absorb all the acid mist, so the treated gas may still contain a certain amount of pollutants and need to be discharged into the atmosphere.

[0005] Acid mist spray tower is a kind of equipment specially used for treating acidic substances in industrial exhaust gas, especially sulfuric acid droplets. It absorbs and neutralizes sulfuric acid in the gas by spraying alkaline solution, such as limestone slurry, to reduce the pollution of acid gas to the environment. The tower consists of absorption liquid storage tank, spraying system, packing layer, flue gas inlet and outlet, control system and exhaust port.

[0006] The mechanism of action of the acid mist spray tower is that when the flue gas containing sulfuric acid passes through the tower body, the alkaline solution is sprayed down from the top of the tower, reacting with the sulfuric acid in the flue gas to generate sulfates and other by-products, thereby reducing the acid gas content in the flue gas. In this way, the acid mist spray tower effectively reduces the emission of acidic pollutants and protects the environment and human health.

[0007] Existing multi-stage acid mist treatment devices are generally being improved with respect to the cooling treatment rate and effect of the acid mist. For example, a multi-stage acid mist treatment device disclosed in the authorized Chinese patent CN212680531U can perform multi-stage heat exchange on the acid mist through the coordinated use of structures such as the acid mist chamber, the acid mist inlet pipe, the flow heat exchange chamber, the drain pipe, the chilled water chamber, the chilled water inlet pipe and the chilled water outlet pipe, and has high cooling efficiency.

[0008] However, the acid mist treatment facilities in the above cited documents, especially the acid mist spray tower, although they occupy an important position in industrial applications, still have significant limitations in their efficiency and effect. These limitations are mainly due to the design of a single tower body, which leads to obvious deficiencies in the treatment process. The acid mist spray tower in the above cited documents is usually equipped with only one tower body. When treating high-concentration acid mist, it may be difficult to maintain a stable treatment effect due to excessive load, which means that they can only perform primary treatment on the acid mist entering the system. Due to the complex composition of acid mist, it may contain a variety of acid gases. The design of a single tower body cannot achieve effective separation and absorption of all types of acid gases. Therefore, even after treatment, the exhaust gas may still contain trace amounts of pollutants, which still pose a potential threat to the environment. At the same time, there is a lack of effective connection and support structure between the acid mist spray tower and the exhaust pipeline. This design negligence not only affects the stability of the entire system, but also increases the risk of equipment damage due to vibration or impact. Especially in harsh industrial environments, the instability of this connection may cause acid mist leakage, thereby posing a threat to the surrounding environment and the safety of operators.

[0030] 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 in 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.

[0031] See also Figure 1-3 The utility model provides a technical solution: a multi-stage acid mist treatment device, comprising a foundation 1, a primary acid mist spray treatment tower 2, a No. 1 connecting pipe 3, a No. 2 connecting pipe 5, a discharge pipe 7 and a maintenance ladder 8, the number of the maintenance ladders 8 is two, and they are installed based on the ground, and the two maintenance ladders 8 are located on both sides of the foundation 1, and the primary acid mist spray treatment tower 2, the No. 2 acid mist spray treatment tower 4 and the discharge pipe 7 are installed in sequence on the side of the foundation 1 away from the ground, the primary acid mist spray treatment tower 2 is connected to the No. 2 acid mist spray treatment tower 4 through the No. 1 connecting pipe 3, the No. 2 acid mist spray treatment tower 4 is connected to the discharge pipe 7 through the No. 2 connecting pipe 5, the outer sides of the No. 1 connecting pipe 3 and the No. 2 connecting pipe 5 are connected with support mechanisms 600, the number of the support mechanisms 600 is a plurality of groups and are respectively connected to the primary acid mist spray treatment tower 2 and the No. 2 acid mist spray treatment tower 4, and the support mechanisms 600 are used to provide support for the No. 1 connecting pipe 3 and the No. 2 connecting pipe 5.

[0032] It can effectively deal with the acid mist emission problems in various industrial environments. The device is mainly composed of a foundation 1, a primary acid mist spray treatment tower 2, a second acid mist spray treatment tower 4, a first connecting pipeline 3, a second connecting pipeline 5, a discharge pipe 7 and a maintenance ladder 8. These components cooperate with each other to form an efficient and stable acid mist treatment system.

[0033] The foundation 1 of the device firmly supports the whole system, ensuring the stability and safety of all components. On one side of the foundation 1, a primary acid mist spray treatment tower 2 is installed, which is the core part of the whole system and is responsible for the preliminary treatment of acid mist. The primary acid mist spray treatment tower 2 is connected to the secondary acid mist spray treatment tower 4 through the No. 1 connecting pipe 3, which further enhances the acid mist treatment capacity and realizes the secondary treatment of acid mist. The No. 2 acid mist spray treatment tower 4 is connected to the discharge pipe 7 through the No. 2 connecting pipe 5, and finally the treated gas is safely discharged into the atmosphere;

[0034] In order to support these pipelines, the device adopts a supporting mechanism 600, which is divided into multiple groups and respectively connected to the first-level acid mist spray treatment tower 2 and the second acid mist spray treatment tower 4. They not only provide necessary support for the pipelines, but also ensure the stability and safety of the entire system;

[0035] In addition, the design of the device takes into account the convenience and safety of operation. Two maintenance ladders 8 are located on both sides of the foundation 1, providing convenient passages for maintenance and inspection. This design takes into account the safety of the operator and ensures that the operator can safely reach various working positions during maintenance or inspection.

[0036] The multi-stage acid mist treatment device realizes a dual treatment mechanism by adding a secondary treatment tower. This design significantly improves the dispersion and absorption efficiency of acid mist, allowing the acid mist to be dispersed and absorbed over a longer distance, thereby greatly reducing the pressure on a single treatment tower. This not only improves the efficiency of acid mist treatment, but also extends the service life of the equipment and reduces maintenance costs.

[0037] At the same time, the added support connection device enhances the stability of the entire system, ensuring that the two treatment towers can work together and maintain balance during the acid mist treatment process. This design reduces the safety risks caused by vibration or tilting and improves the safety of operators;

[0038] In summary, the multi-stage acid mist treatment device, through its unique design and efficient operation mechanism, not only improves the efficiency and stability of acid mist treatment, but also reduces maintenance costs and operational risks. It is the preferred solution for acid mist treatment in industrial environments.

[0039] In this embodiment, the support mechanism 600 is a structure used to improve the efficiency of acid mist dispersion and absorption, and can disperse and absorb the acid mist over a longer distance.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the supporting mechanism 600 includes fixed connection supports 601 respectively fixedly connected to the outer sides of the primary acid mist spray treatment tower 2 and the secondary acid mist spray treatment tower 4, and the number of the fixed connection supports 601 is multiple, a clamping and fixing component and a fastening component connected to the clamping and fixing component are installed on one side of the fixed connection support 601, an adjusting and reinforcing component and two groups of auxiliary moving components respectively connected to the adjusting and reinforcing components and in mirror symmetry are installed on one side of the clamping and fixing component, the primary acid mist spray treatment tower 2 and the secondary acid mist spray treatment tower 4 are respectively located in the corresponding clamping and fixing components, the fastening components are used to adjust the tightness of the clamping and fixing components, and the auxiliary moving components follow the movement of the adjusting and reinforcing components.

[0041] It should be noted that the clamping and fixing assembly includes a No. 1 semi-lunar connecting frame 6021 and a No. 2 semi-lunar connecting frame 6022; one side of the No. 1 semi-lunar connecting frame 6021 is fixedly connected to one side of the fixed connecting support 601, and one end of the No. 1 semi-lunar connecting frame 6021 is hinged to one end of the No. 2 semi-lunar connecting frame 6022 through a pin shaft. The structure not only provides the necessary support, but also ensures the stability of the connecting frame during the operation of the system. The fixed connecting support 601 serves as the base of the entire clamping and fixing assembly. Its design fully considers the rigidity and durability of the structure to ensure that it is not easily deformed or damaged during long-term use.

[0042] One end of the first half-moon-shaped connecting frame 6021 is hinged to one end of the second half-moon-shaped connecting frame 6022 through a pin. The design of the pin allows flexible relative movement between the two connecting frames, which not only increases the flexibility of the assembly, but also makes it easy to adjust the position of the pipeline when necessary. The second half-moon-shaped connecting frame 6022 and the first half-moon-shaped connecting frame 6021 form a stable "full moon" structure.

[0043] The design of this clamping and fixing component fully considers the needs of pipe fixing and adjustment, and through the clever cooperation of the half-moon-shaped connecting frame, the first connecting pipe 3 and the second connecting pipe 5 are firmly fixed. This structure not only ensures the stability of the pipe in the system, but also improves the safety and reliability of the entire system. Through this sophisticated design, it is ensured that during the operation of the system, whether it is the position adjustment or fixing of the pipe, it can achieve efficient and accurate results, thereby ensuring the stable operation of the entire system.

[0044] It can be understood that the fastening assembly includes a No. 1 threaded rod 6031 and an adjustable threaded sleeve 6032; one end of the No. 1 threaded rod 6031 is fixedly connected to one side of the No. 1 semi-lunar connecting frame 6021, and the other end thereof passes through one side of the No. 2 semi-lunar connecting frame 6022 and is threadedly connected to the No. 2 semi-lunar connecting frame 6022, and the outer side of the No. 1 threaded rod 6031 is threadedly connected to the inner side of the adjustable threaded sleeve 6032, so as to clamp and fix the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5 through the mutual cooperation of the No. 1 semi-lunar connecting frame 6021 and the No. 2 semi-lunar connecting frame 6022, and by rotating the adjustable threaded sleeve 6032, it moves on the outer side of the No. 1 threaded rod 6031 under the thrust of the thread rotation, and continuously presses the No. 2 semi-lunar connecting frame 6022 toward the direction of the No. 1 semi-lunar connecting frame 6021, so as to perform preliminary fastening.

[0045] In addition, the adjustment and reinforcement assembly includes a No. 2 threaded rod 6041, a rotating handle 6042 and a crescent-shaped pressure plate 6043; one end of the No. 2 threaded rod 6041 passes through the No. 2 semi-lunar connecting frame 6022 and is rotatably connected to one side of the crescent-shaped pressure plate 6043 through a bearing, and the other end is fixedly connected to one side of the rotating handle 6042, and the outer side of the No. 2 threaded rod 6041 is threadedly connected to the inner side of the No. 2 semi-lunar connecting frame 6022, so as to adjust the No. 2 threaded rod 6041 and the No. 2 semi-lunar connecting frame 6022. Under the action of the threaded connection, it moves in the No. 2 semi-lunar connecting frame 6022 and pushes the crescent-shaped pressure plate 6043 to move, thereby further improving the tightness of the installation of the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5. The position of the No. 2 threaded rod 6041 is adjusted by rotating the handle 6042, so that the operator can flexibly adjust the position of the crescent-shaped pressure plate 6043 according to actual conditions to adapt to the installation requirements of pipes of different sizes and shapes, further improving the flexibility of use and the scope of application of the adjustment and reinforcement component.

[0046] In this embodiment, the turning handle 6042 drives the second threaded rod 6041 to rotate, so as to drive the second threaded rod 6041 to move in the second half-moon connecting frame 6022 under the thrust of the thread rotation, and push the crescent-shaped pressure plate 6043 to move, and the auxiliary moving component moves accordingly, so as to be able to stably push the crescent-shaped pressure plate 6043 to move.

[0047] It should also be noted that the auxiliary moving component includes a sliding rod 6051 and a limit block 6052; one end of the sliding rod 6051 passes through the second semi-lunar connecting frame 6022 and extends to one side of the crescent-shaped pressure plate 6043 and is fixedly connected to one side of the crescent-shaped pressure plate 6043, and the other end is fixedly connected to one side of the limit block 6052, in order to assist the stability of the movement of the crescent-shaped pressure plate 6043, so as to stably press the No. 1 connecting pipe 3 and the No. 2 connecting pipe 5.

[0048] The working principle of the above embodiment is:

[0049] S1 Preliminary treatment of acid mist:

[0050] The acid mist first enters the primary acid mist treatment tower 2, where the acid mist contacts water or other neutralizers to preliminarily remove harmful substances in the acid mist. This step is to reduce the workload of subsequent treatment towers and improve treatment efficiency.

[0051] Secondary treatment of S2 acid mist:

[0052] The acid mist after primary treatment enters the No. 2 acid mist spray treatment tower 4 through the No. 1 connecting pipe 3, where the acid mist contacts with water or other more effective neutralizers again to further remove harmful substances in the acid mist. This step improves the treatment effect and ensures that the gas discharged into the atmosphere meets environmental protection standards.

[0053] S3 support and connection:

[0054] When it is necessary to fix the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5, firstly, the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5 is sleeved between the No. 1 semi-lunar connecting frame 6021 and the No. 2 semi-lunar connecting frame 6022, and then the tightness of the No. 1 semi-lunar connecting frame 6021 and the No. 2 semi-lunar connecting frame 6022 is adjusted by twisting the adjustable threaded sleeve 6032. Under the threaded connection between the No. 1 threaded rod 6031 and the adjustable threaded sleeve 6032, the adjustable threaded sleeve 6032 continuously squeezes the No. 2 semi-lunar connecting frame 6022, so that the No. 2 semi-lunar connecting frame 6022 gradually sticks to the No. 1 semi-lunar connecting frame 6021. By tightening, the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5 can be initially fixed, and then the handle 6042 is held and rotated. Under the rotation support of the bearing and the thrust of the thread rotation, the No. 2 threaded rod 6041 moves inside the No. 2 half-moon connecting frame 6022. Since the sliding rod 6051 and the No. 2 half-moon connecting frame 6022 are slidably connected, the No. 2 threaded rod 6041 can stably push the crescent-shaped pressure plate 6043 to move when it moves. When the crescent-shaped pressure plate 6043 is tightly fitted with the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5, the No. 1 connecting pipe 3 or the No. 2 connecting pipe 5 can be reinforced.

[0055] S4 Emissions:

[0056] The acid mist after two-stage treatment is finally safely discharged into the atmosphere through the discharge pipe 7. The design of the discharge pipe ensures that the treated gas will not cause secondary pollution to the environment.

[0057] S5 maintenance and inspection:

[0058] Two maintenance ladders 8 are located on both sides of the foundation 1, providing convenient passages for maintenance and inspection. This design takes the safety of operators into consideration, ensuring that operators can safely reach various working positions during maintenance or inspection.

[0059] S6 system operation process:

[0060] The acid mist enters the primary acid mist spray treatment tower 2 through the pipeline system, and after preliminary treatment, enters the secondary acid mist spray treatment tower 4 for secondary treatment. During the treatment process, the support mechanism 600 provides the necessary support and stability. After the treatment is completed, the treated gas is safely discharged through the exhaust pipe 7. The design of the maintenance ladder 8 makes the maintenance and inspection of the equipment simple and safe.

[0061] Compared with the prior art: the multi-stage acid mist treatment device realizes double treatment by using the mutual cooperation among the first-stage acid mist spray treatment tower 2, the first connecting pipeline 3, the second acid mist spray treatment tower 4, the second connecting pipeline 5, the supporting mechanism 600, the discharge pipe 7 and the maintenance ladder 8 on the foundation 1, and the double treatment is realized by adding a spray tower. The double treatment mechanism significantly improves the efficiency of acid mist dispersion and absorption, and can make the acid mist dispersed and absorbed within a longer distance, thereby greatly reducing the pressure of a single tower, and can more thoroughly remove harmful substances in the acid mist, which not only improves the treatment efficiency, but also prolongs the service life of the equipment and reduces the maintenance cost. At the same time, a device for supporting and connecting between the acid mist spray tower and the pipeline is added, which greatly enhances the stability of the whole system, ensures that the two towers can work together and maintain balance during the acid mist treatment process, reduces the safety risks that may be caused by vibration or tilting, and improves the safety of operators, thereby improving the efficiency and stability of acid mist treatment, and enhancing safety, and solving the problems of unstable treatment effect, inability to effectively separate and absorb multiple acid gases and unstable connection structure of the existing acid mist spray tower when treating high-concentration acid mist.
