Revealing the secret: Zhongtong Bus promotes in-depth treatment of welding fume, and this machine has become a bright spot!

With the development of welding technology, my country has opened a new era of welding for automobile. However, environmental protection issues followed, and the fume and dust pollution produced by welding brought great dangers to the health of front-line employees.

It is understood that since 2011 in China, the quantity of people suffering from pneumoconiosis in the automobile manufacturing industry has increased dramatically, which has had a huge negative impact on workers and enterprises. At the same time, the increasingly strict environmental assessment system is also spurring many automobile manufacturers, and the control of welding fume is urgent.

Are you still using pipeline fume extraction system to remove welding fume? Zhongtong Bus said: This method is weak!

In the past automobile manufacturing companies, most of the welding fume control adopted a pipeline fume extraction system to collect and discharge the fume. For small enterprises, this method can still barely support, but for those large-scale enterprises whose production capacity is increasing year by year, the traditional pipeline + suction arm system has obviously affected the production efficiency of the enterprise ( Such as workers need to move the suction hood at any time, the production efficiency will be reduced; when welding large and special-shaped parts, they must be hoisted at any time, etc.). For this reason, they need a more convenient and efficient welding fume control plan urgently.

Here, we must mention Zhongtong Bus. As a representative enterprise of China's bus manufacturing, they joined hands with Power Space Environmental Protection to implement an air self-circulation welding fume control plan, which will undoubtedly set a good example for the whole automobile manufacturing industry.

Analysis of Zhongtong Bus:

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.

The final fume extraction plan of Zhongtong Bus:

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.

At present, this air self-circulation fume extraction tower has passed the acceptance inspection. And are used in the Zhongtong Bus’ workshop.
