Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum part oxidation waste gas treatment equipment, and more specifically, particularly relates to aluminum part oxidation waste gas treatment equipment. Background Art

[0002] In mechanical processing, aluminum surfaces are usually treated by anodizing. By selecting electrolytes of different types and concentrations and controlling the process conditions during oxidation, aluminum parts can obtain an anodized film with different properties and a thickness of about tens to hundreds of microns, which significantly improves and enhances the corrosion resistance, wear resistance and decorative properties of the aluminum surface. In the process of anodizing, a large amount of dust containing aluminum oxide and fluoride will be produced. This dust will affect the pollination of crops and have a certain impact on the respiratory system of humans and livestock. Aluminum parts usually need to be pre-treated before anodizing. The pre-treatment process includes an acid etching process, which is usually carried out in an acid pickling tank. A large amount of acid mist waste gas will be generated during the pickling process. Therefore, it is necessary to use aluminum oxidation waste gas treatment equipment to treat the dust and acid mist waste gas containing aluminum oxide and fluoride generated during the aluminum anodizing process. The existing aluminum oxidation waste gas treatment equipment is usually composed of an exhaust hood, an induced draft fan, a pipeline, an acid gas purification tower and a filtering device. When in use, the suction force generated by the induced draft fan enables the exhaust hood to absorb the waste gas generated during the aluminum anodizing process. The waste gas enters the filtering device through the pipeline to remove the dust containing aluminum oxide and fluoride in the waste gas, and then enters the acid gas purification tower. The acid gas purification tower will perform acid and alkali spray neutralization and selective catalytic reduction treatment on the waste gas. After the waste gas treatment is completed, it can be discharged to the outside.

[0003] The existing application number is: CN202020301111.7. The utility model discloses an aluminum oxidation waste gas treatment device, and the key points of its technical solution are: it includes a pickling tank and a waste gas treatment device connected to the pickling tank, the waste gas treatment device includes a liquid neutralization device, a purification device and an exhaust chimney, a suction fan is provided between the purification device and the exhaust chimney, a gas supply pipe is provided between the liquid neutralization device and the inside of the pickling tank, a chemical reagent for neutralizing acidic gas is provided inside the liquid neutralization device, and a uniform wind grid is arranged between the liquid neutralization device and the purification device. The purification device includes two layers of filter screens and an activated carbon layer located between the two layers of filter screens, which improves the acid gas purification efficiency and purifies the environment in the factory building at the same time.

[0004] Based on the above, when the filtering device treats dust containing aluminum oxide and fluoride, it usually uses the static electricity generated by the high-voltage electric field to charge the dust containing aluminum oxide and fluoride. Under the action of the electric field, the charged aluminum oxide and fluoride dust are separated from the exhaust gas, move to the cathode and anode respectively and adhere to the static electrode plate, and then the static electrode plate is vibrated and cleaned by a vibrating device to make the accumulated dust fall into the ash hopper, thereby achieving the purpose of removing the dust containing aluminum oxide and fluoride in the exhaust gas. Then, the exhaust gas generated during the aluminum anodizing process will contain some water vapor, which will cause the aluminum oxide and fluoride dust to adhere to the static electrode plate to a certain extent. If the static electrode plate is only vibrated and cleaned by the vibrating device, there is a problem of incomplete cleaning. If the static electrode plate is not cleaned for a long time, it is easy to affect the ability of the static electrode plate to adsorb aluminum oxide and fluoride dust, thereby affecting the effect of exhaust gas treatment.
