Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an acid-base neutralization reaction tank with automatic sewage discharge. Background Technology

[0002] In modern industrial production and environmental protection, acid-base neutralization reactions play a crucial role in wastewater treatment. With the accelerating pace of industrialization, various industrial activities such as chemical, pharmaceutical, electroplating, and textile printing and dyeing industries generate large amounts of wastewater containing acidic and alkaline components daily. If this wastewater is discharged directly without effective treatment, it will cause devastating damage to natural aquatic environments, leading to pH imbalances, affecting the survival and reproduction of aquatic organisms, disrupting the balance and stability of the entire aquatic ecosystem, and ultimately posing a serious threat to human health and sustainable socio-economic development.

[0003] Existing acid-base neutralization reactors often lack effective stirring drives and flexible stirring component designs during acid-base neutralization reactions. They typically employ relatively fixed and singular stirring methods, such as simple single-shaft impellers. The limited movement patterns of these impellers make it difficult to create a sufficiently uniform stirring flow field throughout the reaction vessel. This results in incomplete mixing of the wastewater and neutralizing agent during wastewater treatment, uneven contact between acid and base molecules, and the potential for over-reaction in certain areas, causing the pH in those areas to deviate from the ideal value. Meanwhile, other areas may experience incomplete reaction, ultimately hindering the overall neutralization process, reducing reaction efficiency, and affecting the subsequent compliance of wastewater discharge standards.

[0004] Current acid-base neutralization reaction tanks lack adequate scraper protection and automated sediment removal mechanisms. In many cases, the scrapers remain inside the reaction vessel continuously, both during the neutralization reaction and during the post-reaction cleaning phase. Prolonged contact with wastewater containing acids and alkalis, as well as the resulting sediment, makes them highly susceptible to corrosion, shortening their lifespan. Frequent scraper replacements increase equipment maintenance costs and workload. Furthermore, sediment removal largely relies on manual operation, requiring periodic shutdowns and personnel to enter the equipment or use simple tools to remove accumulated sediment. This manual cleaning method is not only inefficient but also fails to remove sediment promptly and thoroughly, leading to sediment residue and long-term accumulation within the reaction vessel.

[0005] Based on this, this utility model designs an acid-base neutralization reaction tank with automatic sewage discharge to solve the above problems. Utility Model Content
