Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acid mist treatment, in particular to a device for reducing acid mist generated during production. Background Art
[0002] Sulfuric acid mist, also known as acid fog, usually refers to smoke formed by a large number of floating sulfuric acid particles. It is caused by sulfur oxide waste gas emitted during the combustion of mineral fuels or mineral smelting, sulfuric acid production, etc. It is an atmospheric pollution phenomenon. Sulfuric acid mist occurs in factories that directly produce or use sulfuric acid, and also comes from the exhaust of factories that use coal, petroleum or heavy oil as raw materials and fuels. After the sulfur dioxide gas in the exhaust becomes sulfur trioxide, it combines with moisture in the air to form sulfuric acid mist.
[0003] The utility model disclosed in publication number CN217251428U belongs to the technical field of acid mist collection devices, specifically an acid mist collection device for PCB production, which includes a box and an exhaust fan. The exhaust fan is fixedly installed on the left and right walls of the box. The input end of the exhaust fan is embedded with an exhaust pipe, which runs through the box. The output end of the exhaust fan is connected to an acid mist conveying channel. In this application document, the acid mist generated during the production of the circuit board is extracted by the exhaust fan, and the extracted acid mist is transported to the acid mist collection box through the acid mist conveying channel for easy collection. The acid mist situation during the circuit board processing is detected by a smoke sensor and transmitted to the display screen through a controller. The display screen is convenient for staff to observe, facilitates operation, reduces environmental pollution, and improves the working environment of the staff.
[0004] The existing technology uses an acid mist filter to filter and adsorb acid mist to achieve acid mist control. However, the adsorption and filtration effect of the acid mist filter is limited. If it is not replaced in time, the acid mist may be easily discharged without being filtered, and the control effect is general. Therefore, a device for reducing the generation of acid mist during production is needed to meet the demand. Utility Model Content
