AI Technical Summary
The existing deodorization mechanisms of printing presses are insufficient to meet the requirements of high efficiency, long-lasting and deep purification. Single filtration methods can no longer completely remove odors, and maintenance is inconvenient, affecting the working environment and environmental standards.
It adopts a multi-composite purification design that combines activated carbon filter plates with sodium hydroxide solution. The activated carbon filter plates perform physical adsorption, while the sodium hydroxide solution performs chemical neutralization. Combined with a convenient disassembly structure including a limiting frame, fixing block, locking frame, and torsion spring, it enhances sealing performance and ease of replacement. The motor stirring rod improves the efficiency of the chemical reaction.
It achieves complete odor purification, improves deodorization efficiency and equipment maintenance efficiency, ensures the stability of filtration effect and equipment lifespan, and meets the emission requirements of environmental protection standards.
