Effective fume management in large-scale welding operations requires engineered solutions that balance extraction efficiency with operational practicality. This technical case study examines the implementation of an advanced fume extraction system utilizing self-contained air-clean tower technology to address complex airborne contaminant challenges in an industrial manufacturing environment. The fume extraction clean tower solution delivered superior particulate capture while maintaining full production capabilities.

Project Overview

Zhongtong Bus Holding Co., Ltd. is a heavy industry enterprise headquartered in Liaocheng, Shandong Province, belongs to Liaocheng Zhongtong Automobile Industry Group, and is the third largest bus manufacturer in China.

It is the Zhongtong Bus Factory which needs welding fume control, which has 48 welding machine positions and the welding zone in the south. The distribution of welding machine positions is relatively concentrated; in addition, the size and weight of the welding parts are relatively large. The welding area : north welding zone, the size is about 105*24m, and the south welding zone is about: 98*24m, welding positions are distributed in the welding area, the maximum size of the welding parts is 2500*10000*1500mm.

Traditional ducted extraction systems proved economically and technically unfeasible due to:

• Prohibitive installation costs and extended project timeline

• Structural interference with overhead crane operations

• Inflexibility for future facility reconfiguration

• Significant energy consumption inefficiencies

Technical Specifications: Power Space LW16 Series

Through the comprehensive consideration of construction difficulty, economy, use effect, convenience of later maintenance and influence on the existing layout, Zhongtong Bus finally adopted the "air self-circulation fume extraction tower" to collect and purify the exhaust gas generated during the electric welding process.

The air self-circulation fume extraction tower is different from the traditional pipeline fume extraction system collection method. Its construction period is shorter; Can save workers' the trouble of adjusting position of the suction hood during the work process; And can increase the per capita production capacity. Most importantly, It can truly realize the collection and purification of exhaust gas of the whole workshop.

Conclusion: Optimized Industrial Air Quality Management

This project demonstrates that advanced air-clean tower technology provides superior fume management compared to conventional ducted systems. The implemented fume extraction system delivered exceptional particulate capture while maintaining operational flexibility and reducing total cost of ownership.
