Description

Technical Field

[0001] This utility model belongs to the field of acid mist treatment technology, specifically, it relates to an acid mist absorption device. Background Technology

[0002] Hot-dip galvanizing is a process of coating the surface of an object. When workers galvanize the object, acid mist is generated. If the acid mist is discharged directly, it will cause environmental pollution. Therefore, acid mist absorption and purification devices are needed to treat the acid mist before it is discharged to reduce environmental damage.

[0003] A document with publication number CN219744428U discloses an acid mist absorption and purification device for hot-dip galvanizing, comprising an absorption tower, an acid mist dispersion component, an alkaline spray component, an air inlet component, and an air outlet component. To address the shortcomings of acid mist purification towers in operation, such as short residence time of acid mist within the tower and small contact area between acid mist and alkaline solution, the aforementioned device uses the air inlet component to introduce acid mist into the absorption tower through multiple air outlets for initial dispersion. The acid mist dispersion component drives the dispersion blades to rotate, further dispersing the gas and increasing the contact area between the gas and alkaline solution, thereby improving the purification effect. The air outlet component extends the residence time of the gas within the tower, increasing the neutralization reaction time between the alkaline solution and the acid mist, thus further enhancing the purification effect.

[0004] The above-mentioned device increases the neutralization reaction time by extending the flow path of acid mist in the device. However, the above-mentioned device is not applicable in actual hot-dip galvanizing workshops because the device occupies a large space and the single device has limited efficiency in absorbing and treating acid mist in the workshop.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problems of acid mist treatment, the basic concept of the technical solution adopted by this utility model is as follows: An acid mist absorption device includes a treatment component for treating acid mist. The treatment component includes a cylinder, legs, a cover, a treatment liquid pipeline, and an exhaust pipe. The legs are symmetrically arranged at the bottom of the cylinder, and each leg is fixedly connected to the corresponding cylinder. The cover is arranged on one side of the cylinder. The treatment liquid pipeline is fixedly connected to the bottom of the cylinder, and the exhaust pipe is fixedly connected to the top of the cylinder.

[0007] In a preferred embodiment of this utility model, an exhaust fan module is fixedly connected to the middle of the cover, and a cooling pipe is provided between the cover and the exhaust fan module. The cooling pipe is used to heat the acid mist, and the exhaust fan module is provided with an air inlet pipe.

[0008] In a preferred embodiment of this utility model, the end of the air inlet pipe is fixedly connected to the exhaust fan module, and the air inlet pipe is fixedly connected to the cylinder body. The other end of the air inlet pipe is fixedly connected to the reaction cylinder, and the inside of the reaction cylinder is hollow.

[0009] In a preferred embodiment of the present invention, the bottom of the reaction cylinder is connected to a gas delivery ring module via a pipe. The gas delivery ring module is ring-shaped and has multiple nozzles arranged around it.

[0010] In a preferred embodiment of this utility model, the treatment liquid pipes on each of the cylinders are connected by the same connecting pipe, the exhaust pipes on each of the cylinders are connected by the same connecting pipe, and a cover plate is connected to the cylinder by fasteners.

[0011] In a preferred embodiment of this utility model, each of the reaction cylinders is provided with a filter plate, and each filter plate is fixedly connected to the corresponding end of the reaction cylinder.

[0012] In a preferred embodiment of this utility model, a guide plate is provided between the filter plates, and the end of the guide plate is fixedly connected to the corresponding filter plate and the reaction cylinder.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The acid mist absorption device has a snap-fit ​​position at the upper end of the cylinder, and the support legs snap into the corresponding snap-fit ​​position, thereby stacking the cylinders together. This reduces space occupation and can be increased according to the actual working environment. By having multiple cylinders working at the same time, the efficiency of acid mist absorption and treatment is improved.

[0014] 2. This acid mist absorption device uses NaOH particles in a reaction cylinder for initial neutralization treatment. The pre-treated acid mist gas is then fed into a gas delivery ring module. The ring-shaped arrangement of the gas delivery ring module ensures the acid mist gas is evenly sprayed out through nozzles. Furthermore, an alkaline liquid treatment agent at the bottom of the cylinder provides secondary treatment to the acid mist gas. This two-stage neutralization process ensures thorough neutralization of the acid mist gas, thereby reducing space requirements while improving the efficiency of acid mist treatment.

[0015] 3. This acid mist absorption device uses filter plates to filter particles in acid mist gas. A guide plate guides the acid mist gas after the first filtration upwards, preventing it from moving randomly between the filter plates and accumulating. A second filter plate performs a second filtration, thoroughly filtering the particles in the acid mist gas. This simultaneous neutralization reaction and particle filtration of the acid mist gas is achieved.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Please see Figure 1-5 An acid mist absorption device includes a treatment component for treating acid mist. The treatment component includes a cylinder 1, support legs 11, a cover 2, a treatment liquid pipe 3, and an exhaust pipe 4. Support legs 11 are symmetrically arranged at the bottom of the cylinder 1, and each support leg 11 is fixedly connected to the corresponding cylinder 1. The cover 2 is arranged on one side of the cylinder 1. The treatment liquid pipe 3 is fixedly connected to the bottom of the cylinder 1, and the exhaust pipe 4 is fixedly connected to the top of the cylinder 1. Acid mist is drawn into cylinder 1 through hood 2, treated at the bottom of cylinder 1, and then discharged through exhaust pipe 4. Treatment fluid is added or replaced in cylinder 1 through treatment fluid pipe 3. The upper end of cylinder 1 is provided with snap-fit ​​positions, and the support legs 11 snap into the corresponding snap-fit ​​positions, thereby stacking multiple cylinders 1. This reduces space occupation and can be increased according to the actual working environment. The simultaneous operation of multiple cylinders 1 improves the efficiency of acid mist absorption and treatment.

[0021] The hood 2 is fixedly connected to the middle of the exhaust fan module 22. A cooling pipe 21 is provided between the hood 2 and the exhaust fan module 22. The cooling pipe 21 is used to heat the acid mist. The exhaust fan module 22 is provided with an air inlet pipe 23. The end of the air inlet pipe 23 is fixedly connected to the exhaust fan module 22 and the air inlet pipe 23 is fixedly connected to the cylinder 1. The other end of the air inlet pipe 23 is fixedly connected to the reaction cylinder 24. The reaction cylinder 24 is hollow inside. The bottom of the reaction cylinder 24 is connected to a gas delivery ring module 25 through a pipe. The gas delivery ring module 25 is ring-shaped and multiple nozzles are arranged around the gas delivery ring module 25. In the treatment of acid mist, the cooling pipe 21 first cools down the surrounding temperature of the exhaust fan module 22 for a period of time. Then, the exhaust fan module 22 uses the suction force generated during operation to draw the acid mist into the air inlet pipe 23. The acid mist in the air inlet pipe 23 enters the reaction cylinder 24. The hollow environment inside the reaction cylinder 24 is filled with NaOH particles. The NaOH particles in the reaction cylinder 24 perform preliminary neutralization treatment. Then, the acid mist gas after preliminary treatment is input into the gas delivery ring module 25. Through the ring-shaped arrangement of the gas delivery ring module 25, the acid mist gas is evenly sprayed out through the nozzle. The acid mist gas is then treated a second time by the alkaline liquid treatment agent at the bottom of the cylinder 1. Thus, the acid mist gas is fully neutralized through two neutralization reactions, thereby reducing space occupation and improving the efficiency of acid mist treatment. After the cooling pipe 21 cools the surrounding environment of the exhaust fan module 22, it reduces the temperature of the acid mist absorbed into the device, thus preventing the acid mist temperature from being too high and causing the high temperature of the acid mist to be transferred to the alkaline absorption liquid, resulting in a decrease in the solubility of the alkaline absorption liquid and a slowdown in the neutralization reaction rate. The reaction cylinder 24 is connected to the air inlet pipe 23 via a flange, so the space between the air inlet pipe 23 and the reaction cylinder 24 can be disassembled for replenishing and replacing NaOH particles. Since the flange connection is a conventional setting, it is not described in detail in the text and will not be elaborated here. The nozzle on the gas delivery ring module 25 is a one-way valve port. The nozzle can only be entered by acid mist gas, and the alkaline treatment liquid cannot flow back into the gas delivery ring module 25 through the nozzle on the gas delivery ring module 25.

[0022] The treatment liquid pipes 3 on each cylinder 1 are connected through the same connecting pipe 12, the exhaust pipes 4 on each cylinder 1 are connected through the same connecting pipe 12, and the cover plates 13 on the cylinder 1 are connected by fasteners, including but not limited to bolts. The assembled cylinders 1 are connected by connecting pipes 12. The alkaline treatment liquid at the bottom of the cylinder 1 is added or replaced through the treatment liquid pipe 3. The treated gas is discharged through the exhaust pipe 4. The cover plate 13 is fastened to the cylinder 1 and disassembled and reassembled. The space inside the cylinder 1 is replaced and cleaned. The alkaline treatment solution at the bottom of the cylinder 1 is added or replaced through the treatment solution pipeline 3. The extraction and delivery steps are achieved through an auxiliary device, and a valve is installed between the treatment solution pipeline 3 and the bottom of the cylinder 1.

[0023] Each reaction cylinder 24 is provided with a filter plate 5, and each filter plate 5 is fixedly connected to the corresponding end of the reaction cylinder 24. A guide plate 51 is provided between the filter plates 5, and the end of the guide plate 51 is fixedly connected to the corresponding filter plate 5 and the reaction cylinder 24. The acid mist gas treated by the gas conveying ring module 25 and the bottom of the cylinder 1 is filtered by the filter plate 5 to remove particles from the acid mist gas. The guide plate 51 guides the acid mist gas after the first filtration upward to prevent the acid mist gas from moving randomly between the filter plates 5 and accumulating inside. The acid mist gas is then filtered a second time by the second filter plate 5 to fully remove particles from the acid mist gas. The neutralization reaction and particle filtration of the acid mist gas are carried out simultaneously. Furthermore, all components within this device are coated with a corrosion-resistant coating.
