Kaitian Environmental Protection: Health and Environmental Protection in Welding Production

The Importance of Safety and Environmental Protection in Welding

Welders are constantly exposed to various hazards such as intense arc light, welding fumes, toxic gases, high-frequency electromagnetic radiation, noise, and heat. These risks can lead to serious health issues and industrial accidents. In addition, welding fumes can cause environmental pollution if not properly managed.

To minimize these risks, simple protective measures are essential during the welding process. Common protective equipment includes masks, welding goggles, face shields, respirators, helmets, protective clothing, and fans. Simple ventilation systems help remove harmful dust and gases from the immediate working area, offering better protection for workers.

Controlling welding fumes is a major challenge due to their small particle size, which makes filtration difficult. The variability of welding stations also complicates the capture of fumes. Additionally, hot air currents from welding create plume-like behavior, making it hard to manage with standard ventilation techniques. The collection of welding fumes is illustrated in Figures 1 and 2.

Kaitian Environmental’s Key Products and Technologies

As a leading company in environmental solutions, Kaitian Environmental has developed a wide range of eco-friendly products through years of innovation and market experience. Their product line covers comprehensive dust control solutions for welding and cutting processes, including whole-plant welding dust control, plasma and laser welding, robot welding, electrode arc welding, gas shielded welding, plasma cutting, laser cutting, and carbon arc gouging. They also provide solutions for oil mist, emulsion, grinding, polishing, shot blasting, sandblasting, and casting dust, as well as treatment for organic and inorganic waste gases, heavy metals, desulfurization, denitrification, mercury removal, and incineration exhaust.

Kaitian Environmental combines advanced system engineering with constant temperature and humidity control, along with integrated dust and gas treatment technologies. It is the only company in China capable of solving this key technology. Their whole-plant welding fume treatment system is a national invention patent and a major science and technology project in Hunan Province.

Case Study: Zhangjiakou Coal Mine Park

For many years, Kaitian Environmental has provided environmental solutions to subsidiaries of CSR and CNR, as well as to enterprises in the machinery and coal industries. A notable example is the environmental service provided for the planning of the entire Zhangjiakou Coal Mine Park. This large-scale relocation required comprehensive pollution control across all sources. Kaitian analyzed the pollution sources of eight branches and developed customized environmental solutions. These included overall dust removal in welding and resin sand workshops, casting and polishing dust removal, side chain butt welding, quenching oil mist, paint exhaust purification, welding/boring machine oil mist, shot blasting, grinding, electro-hydraulic hammer dust removal, heat treatment oil mist, sprocket welding dust control, and structural welding workshop management. There are dozens of different pollution sources in the park, with over 100 sets of dust removal and purification equipment installed. Several case examples are shown in Figure 3.

The successful implementation of the project resolved long-standing environmental issues at the Zhangjiakou Coal Mine. The environmental protection plan was integrated into the park’s design, resulting in neat and efficient equipment that significantly improved air quality. Not only was the polluted environment remediated, but workers now operate in a safer, healthier setting. This investment in eco-friendly solutions not only protects employee health but also extends the life of processing equipment, enhancing the value for customers. Moreover, Kaitian’s environmentally friendly systems combine dehumidification, temperature control, and dust removal, improving both comfort and energy efficiency, thus meeting the diverse needs of clients.
