Iii. Evolution of Sulfur Guns - The Spirit of Craftsmanship That Strives for Excellence

The sulfur gun, as the core equipment of the sulfuric acid production unit from sulfur, its performance directly determines the operational efficiency and stability of the unit. Lizhenglai has never ceased its innovation in the sulfur gun. Over the past four years, through in-depth theoretical research, continuous optimization of manufacturing technology and the spirit of craftsmanship that pursues excellence, it has completed four major iterations of the sulfur gun and launched the anti-clogging sulfur gun.

Iv. Digital Sulfuric Acid - Ushering in a New Era of Intelligence for Sulfuric Acid Plants

After four years of dedicated research and development, Lizhenglai has successfully launched the "Digital Sulfuric Acid" system, which has been successfully applied in two 800,000-ton sulfuric acid production units from sulfur, achieving remarkable results. This system enables one-click load adjustment and start-up safety inspection of the sulfuric acid plant, achieving three major leaps in the production process:

•Automation: The operation of the equipment shifts from being driven by manual experience to being driven by data intelligence, significantly reducing the operational intensity and human errors.

•Knowledge Assetization: The valuable experience of senior workers is transformed into digital assets that can be accumulated, passed down, and optimized, addressing the industry's pain point of "experience walking away with people".

•Digital Management: Equipment information is transparent and visible, management decisions are based on solid evidence, and operational efficiency is comprehensively enhanced. 

The digital sulfuric acid system has comprehensively addressed the three long-standing predicaments faced by the sulfuric acid industry: the inability of the equipment to achieve intelligent and automatic operation, the difficulty in preserving and passing on production experience, and the prominent issues of information asymmetry and opacity in the equipment.

It is particularly worth noting that as sulfuric acid plants gradually achieve fully automatic operation, the role transformation of traditional operators has become a new topic in the industry - how to shift from "operators" to "optimization engineers" of the plants? In response to the demands of The Times, Lizhenglai has launched the Digital Sulfuric Acid Simulation Function (OTS), aiming to systematically cultivate and optimize engineers for the sulfuric acid industry and provide talent support and intellectual guarantee for the intelligent upgrade of the industry.

V‌: Serving the World - Winning industry trust with professional strength
