Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acid mist treatment, and particularly relates to an acid mist absorption and treatment device for a fuming sulfuric acid loading system. Background Art
[0002] In traditional fuming sulfuric acid loading operations, acid mist emissions have always been an environmental problem that urgently needs to be solved. As a highly corrosive and volatile chemical substance, fuming sulfuric acid is extremely likely to generate a large amount of acid mist during the loading and unloading process. These acid mists contain high-concentration sulfuric acid vapor, which not only poses a serious threat to human health, but also corrodes surrounding equipment, pollutes the atmospheric environment, and violates environmental protection regulations. Previous acid mist treatment devices mostly had problems such as incomplete absorption, slow treatment speed, high energy consumption, and complex maintenance. Especially when dealing with high-concentration and large-flow acid mists, the effects were even more unsatisfactory. For example, the single suction collection and water washing method often leads to too large bubbles, small contact area between acid mist and water, and insufficient absorption; without an effective stirring mechanism, the acid mist and clean water will be unevenly mixed, affecting the absorption efficiency. Therefore, we have proposed an acid mist absorption and treatment device for a fuming sulfuric acid loading system. Content of the Utility Model
