Description

Technical Field

[0001] The utility model relates to the technical field of acid mist treatment, in particular to an acid mist absorption device for a lead electrolysis outlet tank. Background Art

[0002] After a certain period of electrolysis, the plates in the electrolytic cell are removed from the cell using a crane. The crane then moves them to a washing facility to remove impurities and remove any nonferrous metals adsorbed on them. Both the cathode and anode plates are removed together during removal. Due to the temperature difference between the two processes, the residual electrolyte on the plates evaporates, forming acid mist. This acid mist drifts upward, corroding the crane's electrical equipment and wiring. As the crane moves, it gradually spreads throughout the workshop, impacting the environment.

[0003] Acid mist treatment facilities are often located near the electrolytic cell surface, such as induced draft hoods above the cell or ducts around the cell surface. These use negative pressure to extract the acid mist generated during the electrolysis process. After passing through the pipelines, the acid mist is collected in treatment equipment for unified purification. These treatment facilities are only fixed structures and are unable to treat the acid mist generated during the movement of the plates driven by the crane. Summary of the Invention

[0004] In order to solve the problem that acid mist generated in the process of moving the plate driven by a traveling crane is difficult to treat, the utility model provides an acid mist absorption device for a lead electrolysis outlet tank. A follow-up adsorption box is arranged on the traveling crane, and a fan is used to introduce the acid mist into the adsorption box, so that the acid mist is effectively treated by adsorption purification materials.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A lead electrolysis tank acid mist absorption device is installed on a traveling crane and moves with the traveling crane to facilitate the synchronous purification of acid mist generated by the electrode plates. The device comprises an adsorption box, a grid plate, a fan and an alkaline activated carbon layer. The adsorption box is an open-top box structure to facilitate gas outflow. The grid plate is detachably provided inside the adsorption box, facilitating the installation of the grid plate.

[0007] The grille plate divides the adsorption box into an adsorption chamber and an air inlet chamber arranged vertically. The adsorption chamber and the air inlet chamber are connected through the grille plate, and the gas flows from the air inlet chamber to the adsorption chamber. The alkaline activated carbon layer is arranged in the adsorption chamber to facilitate the treatment of acid mist. The alkaline activated carbon layer is arranged above the grille plate to facilitate the support of the alkaline activated carbon layer. A plurality of fans are provided on the side wall of the air inlet chamber to introduce the acid mist into the air inlet chamber.

[0008] Furthermore, the adsorption box is a rectangular structure made of reinforced polypropylene material, which improves the corrosion resistance of the adsorption box. A placement plate is provided on the inner wall of the adsorption box. The placement plate is bent into a "mouth" shape and arranged on the four sides of the adsorption box. The grille plate is arranged on the placement plate to facilitate the support of the grille plate.

[0009] Furthermore, the grid plate is evenly provided with a plurality of eyebolts, each of which passes downward through the alkaline activated carbon layer and connects and fixes the grid plate. The eyebolts facilitate lifting the grid plate and removing the grid plate from the adsorption box.

[0010] Furthermore, the alkaline activated carbon layer is a layer structure formed by laying alkaline honeycomb activated carbon bricks. The activated carbon can physically adsorb the acid mist, and the alkaline activated carbon can also combine with the acid mist to chemically adsorb, thereby neutralizing the acid mist and improving the workshop environment.

[0011] Furthermore, the fans are arranged on the left and right sides and bottom side walls of the air inlet chamber to absorb the acid mist as comprehensively as possible. The fans are fiberglass fans with strong corrosion resistance. A diverter plate is also provided in the air inlet chamber. The diverter plate is arranged in an "eight" shape and is used to evenly separate the fans on different side walls to avoid mutual impact of airflow.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] This utility model features a rational structural design. By arranging fans on multiple side walls of the adsorption chamber, it facilitates the all-around adsorption of acid mist, ensuring that the acid mist enters the air inlet chamber through the fans, thereby controlling the unorganized emission of acid mist. The diverter plate prevents interference between multiple streams of acid mist, thus avoiding convection collisions. The diverter plate evenly directs the acid mist into the adsorption chamber for treatment by the alkaline activated carbon layer.

[0014] The grid plate of the utility model can support the alkaline activated carbon layer, and through the combination of physical adsorption and chemical adsorption of the alkaline activated carbon layer, it is convenient to purify the generated acid mist, avoid the acid gas from corroding the driving frame and electrical appliances, lines and other equipment and facilities, prevent the acid mist from floating in the workshop, improve the workshop working environment, and protect the health of workers.

[0019] The following describes the specific implementation of the present invention in detail with reference to the accompanying drawings:

[0020] like Figures 1 to 3 As shown, an acid mist absorption device for a lead electrolysis tank is mounted on a crane and moves with the crane. This allows for timely and effective absorption of the acid mist generated during the process of lifting and moving the plates. The acid mist absorption device includes an absorption box 1, a grid plate 2, a fan 3, and an alkaline activated carbon layer 4.

[0021] The adsorption chamber 1 is a rectangular parallelepiped structure made of reinforced polypropylene, which provides excellent corrosion resistance. The chamber 1 is open at the top to facilitate the outflow of purified gas. A removable grille plate 2 is installed within the chamber 1. During installation, a support plate 5 is installed on the inner sidewall of the chamber 1. The support plate 5 is bent into a "mouth" shape and arranged around the sides of the chamber 1. The grille plate 2 is placed on the support plate 5, providing support for the grille plate 2.

[0022] The adsorption chamber 1 is divided into an adsorption chamber 6 and an air inlet chamber 7, arranged vertically. The adsorption chamber 6 and the air inlet chamber 7 are connected by the hollow grille 2. Multiple fans 3 are installed on the sidewalls of the air inlet chamber 7 to draw acid mist into the air inlet chamber 7. When running, the fans 3 draw acid mist from the outside into the air inlet chamber 7.

[0023] Specifically, fans 3 are arranged on the left and right sides and the bottom side wall of the air inlet chamber 7. There are two fans 3 on each side. The fans 3 are glass fiber reinforced plastic fans 3, which are a type of anti-corrosion fans 3 and are suitable for the acid mist environment. In order to avoid the turbulence of the airflow introduced by the fans 3, a diverter plate 9 is also provided in the air inlet chamber 7. The diverter plate 9 is arranged in an "eight" shape. The diverter plate 9 is used to evenly separate the fans 3 on different side walls. In this way, the airflows introduced by the fans 3 are independent of each other, avoiding impact and collision between each other. At the same time, the top of the diverter plate 9 extends to the position of the placement plate 5, and cooperates with the placement plate 5 to support the grille plate.

[0024] An alkaline activated carbon layer 4 is provided in the adsorption chamber 6. The alkaline activated carbon layer 4 is a layer structure formed by laying alkaline honeycomb activated carbon bricks. The alkaline activated carbon layer 4 is arranged above the grid plate 2, and the grid plate 2 supports a number of alkaline honeycomb activated carbon bricks. In order to facilitate the removal of the grid plate 2, four lifting eye bolts 8 are evenly provided on the grid plate 2. Each lifting eye bolt 8 passes downward through the alkaline activated carbon layer 4 and the grid plate 2 to connect and fix. By lifting the lifting eye bolt 8, the entire grid plate 2 can be lifted out of the adsorption box 1, and the alkaline activated carbon layer 4 is exposed to the outside, which facilitates the replacement of the alkaline activated carbon layer 4.

[0025] The principle of the present utility model is as follows: the start and stop control of the fan 3 is interlocked with the weighing sensor of the crane. When the crane is lifting the plate, the weighing sensor senses the weight and the fan 3 is turned on. Multiple fans 3 are running at the same time, forming a negative pressure area around the crane, and then the acid mist formed after the plate is out of the tank is absorbed into the air inlet chamber 7. Under the action of the diverter plate 9, the acid mist can be evenly guided into the alkaline activated carbon layer 4. The acid mist flows evenly through the alkaline activated carbon layer 4. During this process, the alkaline activated carbon layer 4 can be physically adsorbed. At the same time, the acid mist and the alkaline substance are chemically neutralized. After being neutralized into neutral gas, it is arranged above the adsorption box 1, thereby effectively treating the acid mist to avoid causing environmental problems.

[0026] After the plate falls, the weighing sensor returns to zero and the interlocking fan 3 stops. After the alkaline activated carbon layer 4 has been used for a long time and is detected to be acidic, it is necessary to replace the alkaline activated carbon layer 4 in time.

[0027] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
