破解制罐车间"高烤"难题：瑞峰环保超大跨度空间通风降温工程纪实  

【项目背景】

在广东省中北部，清远市佛冈县以其独特的区位优势，正成为环珠三角产业转移的重要承接地。这里属亚热带季风气候，夏季漫长且高温高湿，对工业生产环境的通风降温提出了严峻挑战。佛冈及其所在的清远地区，依托邻近广州、东莞等制造业中心的便利，大力发展金属制品、装备制造等产业，形成了显著的集群效应。

本次项目的客户——广东吉多宝制罐有限公司，便是这一产业链上的关键一环。作为一家专业生产各类饮料罐、食品罐的现代化企业，其产品对生产环境的洁净度、温湿度有着严苛的要求。制罐工艺主要涉及铝材、马口铁的冲压、焊接、涂布等工序，这些精密设备在运行时会产生大量热量，且生产过程中对空气中的尘埃粒子极为敏感，任何环境波动都可能影响罐体的密封性与涂层附着力，进而关乎食品安全。因此，一个高效、洁净、稳定的车间环境，是保障产品质量与生产效率的生命线。

【项目挑战】

吉多宝的制罐车间是一个超大型的单体空间：建筑面积达 12000平米，层高高达 17米。厂房主体采用重型工字钢框架结构，确保了大跨度空间的承重稳固；墙体为砖砌结构，屋顶铺设隔热彩钢瓦，采光良好但密封性较强。这种"大平层、高挑空、强密封"的结构，在广东漫长的夏季里，无疑会成为一个巨大的"温室"。车间内，众多冲压线和涂布生产线高速运转，设备散热与人员密集度叠加，导致内部热量和浊气难以自然排出，不仅严重影响一线员工的体感舒适度与工作效率，更对高精度的生产设备稳定运行和产品良率构成潜在威胁。由于生产工艺未涉及行车作业，车间上空净空条件极佳，这为采用大型风管进行远距离、有组织的送风系统，提供了得天独厚的先天条件。

【定制化方案】

面对"高温、高湿、超大空间、高洁净要求"的多重挑战，瑞峰环保的方案设计人员深入现场，综合考量了当地气候特点、厂房结构特征、生产工艺要求以及洁净度标准等核心因素，为其量身定制了一套开创性的解决方案：

"大风量蒸发式冷风机 + 长风管特殊布局"组合系统

1、创新布局，释放空间： 我们将核心降温设备——大风量加高型蒸发式冷风机，巧妙地安装在建筑墙体外侧。这一设计不仅彻底避免了占用宝贵的室内生产面积，更确保了源源不断的新鲜冷气从室外引入。

2、精准送风，全面覆盖： 通过精心设计的长风管网络，将处理后的冷空气精准、均匀地输送到车间的每一个角落。长达数十米的风管布局，完美匹配了17米层高带来的广阔空间，有效解决了大跨度厂房送风距离不足的行业难题。

3、正压通风，高效换气： 系统利用大风量产生的微正压环境，持续将室内人员、设备产生的热气、粉尘和浊气通过预设的排风口或门窗缝隙"挤"出室外。其背后的物理原理很简单：持续的冷空气注入形成气压差，如同无形的空气活塞，推动污浊空气排出，从而实现每分钟高达数十次的换气效率，让车间时刻保持清新、凉爽。

4、洁净为本，材质升级： 针对制罐工艺对产品洁净度的极高要求，我们突破常规，摒弃了传统易生锈、积尘的镀锌铁皮风管，创新性地选用了环保复合材料定制风管。这种材料表面光洁、不产尘、不积尘，且防腐蚀、防锈蚀，从根本上杜绝了二次污染，为食品级罐体的生产环境提供了坚实保障。

【项目成效与深远影响】

系统投入使用后，效果立竿见影。车间内温度显著下降，空气流动性大幅增强，闷热感一扫而空。员工们普遍反映工作环境变得舒适宜人，工作积极性与专注度明显提升。更重要的是，稳定、洁净的空气环境，为精密设备的可靠运行和产品品质的持续稳定提供了有力支撑。

此项目虽然是为一家制罐企业量身打造，但其成功经验与解决方案，具有极强的可复制性与推广价值。它雄辩地证明，瑞峰环保不仅精通于某一类行业的工程，更具备针对超大、超高、超复杂空间的"诊断"能力，以及为特殊工艺要求下的生产环境，进行设备综合选型、方案深度设计与精细化施工的系统性实力。

无论是闷热的机械加工车间，还是对洁净度有严苛要求的食品、电子厂房，只要您面临通风降温的难题，瑞峰环保都能为您提供专业、可靠、量身定制的解决方案。

Cracking the "high baking" problem in the canning workshop: a documentary on the ventilation and cooling project of Ruifeng Environmental Protection's ultra large span space

[Project Background]

In the central northern part of Guangdong Province, Fogang County in Qingyuan City is becoming an important recipient of industrial transfer around the Pearl River Delta due to its unique geographical advantages. This area has a subtropical monsoon climate, with long and high temperature and humidity summers, posing a severe challenge to ventilation and cooling in industrial production environments. Fogang and its Qingyuan region, relying on the convenience of neighboring manufacturing centers such as Guangzhou and Dongguan, have vigorously developed industries such as metal products and equipment manufacturing, forming a significant cluster effect.

The client of this project, Guangdong Jiduobao Can Making Co., Ltd., is a key link in this industry chain. As a modern enterprise specializing in the production of various beverage cans and food cans, its products have strict requirements for the cleanliness, temperature, and humidity of the production environment. The canning process mainly involves stamping, welding, coating and other processes of aluminum and tinplate. These precision equipment generate a large amount of heat during operation, and are extremely sensitive to dust particles in the air during the production process. Any environmental fluctuations may affect the sealing and coating adhesion of the can body, which is related to food safety. Therefore, an efficient, clean, and stable workshop environment is the lifeline to ensure product quality and production efficiency.

Project Challenge

Jiduobao's canning workshop is a super large single space with a building area of 12000 square meters and a floor height of up to 17 meters. The main body of the factory adopts a heavy-duty I-beam frame structure, ensuring the load-bearing stability of large-span spaces; The wall is constructed with bricks, and the roof is covered with insulated color steel tiles, providing good lighting but strong sealing. This "large flat layer, high ceiling, strong sealing" structure will undoubtedly become a huge "greenhouse" during the long summer in Guangdong. In the workshop, numerous stamping and coating production lines operate at high speeds, and the heat dissipation of equipment and personnel density overlap, making it difficult for internal heat and turbidity to be naturally discharged. This not only seriously affects the comfort and work efficiency of frontline employees, but also poses a potential threat to the stable operation of high-precision production equipment and product yield. Due to the absence of crane operations in the production process, the workshop has excellent air clearance conditions, which provides a unique advantage for using large air ducts for long-distance and organized air supply systems.

Customized Solution

Faced with multiple challenges such as high temperature, high humidity, large space, and high cleanliness requirements, the design team of Ruifeng Environmental Protection went deep into the site and comprehensively considered core factors such as local climate characteristics, factory structure characteristics, production process requirements, and cleanliness standards. They tailored a pioneering solution for it:

Combination system of high air volume evaporative air cooler and special layout of long air duct

1. Innovative layout, freeing up space: We have ingeniously installed the core cooling equipment - a high air volume and elevated evaporative air cooler - on the outside of the building wall. This design not only completely avoids occupying valuable indoor production area, but also ensures a continuous supply of fresh air conditioning from outside.

2. Accurate air supply, comprehensive coverage: Through a carefully designed long air duct network, the processed cold air is accurately and evenly delivered to every corner of the workshop. The air duct layout, which is tens of meters long, perfectly matches the vast space brought by the 17 meter floor height, effectively solving the industry problem of insufficient air supply distance for large-span factories.

3. Positive pressure ventilation, efficient ventilation: The system utilizes the micro positive pressure environment generated by high air volume to continuously "squeeze" the hot air, dust, and turbidity generated by indoor personnel and equipment out of the room through preset exhaust vents or door and window gaps. The physical principle behind it is simple: continuous injection of cold air creates a pressure difference, like an invisible air piston, pushing polluted air out, thereby achieving a ventilation efficiency of up to dozens of times per minute, keeping the workshop fresh and cool at all times.

4. Cleanliness oriented, material upgrade: In response to the extremely high requirements for product cleanliness in the canning process, we have broken through the norm and abandoned the traditional galvanized iron sheet air ducts that are prone to rust and dust accumulation. We have innovatively selected environmentally friendly composite materials for customized air ducts. This material has a smooth surface, does not produce or accumulate dust, and is corrosion-resistant and rust proof, fundamentally eliminating secondary pollution and providing a solid guarantee for the production environment of food grade tanks.

Project effectiveness and far-reaching impact

After the system was put into use, the effect was immediate. The temperature in the workshop has significantly decreased, the air flow has greatly increased, and the stuffiness has been swept away. Employees generally report that the working environment has become comfortable and pleasant, and their work enthusiasm and focus have significantly improved. More importantly, a stable and clean air environment provides strong support for the reliable operation of precision equipment and the sustained stability of product quality.

Although this project is tailored for a canning enterprise, its successful experience and solutions have strong replicability and promotional value. It eloquently proves that Ruifeng Environmental Protection is not only proficient in engineering in a certain industry, but also has the ability to "diagnose" super large, super high, and super complex spaces, as well as the systematic strength to comprehensively select equipment, deeply design schemes, and refine construction for production environments with special process requirements.

Whether it is a hot and humid mechanical processing workshop or a food or electronic factory with strict cleanliness requirements, as long as you face the problem of ventilation and cooling, Ruifeng Environmental Protection can provide you with professional, reliable, and customized solutions.
