箱梁内焊接排烟降温系统

System for exhaust smoke and drop in temperature during welding inside box beams

提出了箱梁内焊接的热力学模型和烟尘冶理目标的计算公式。研制的排烟降温系统，具有根据季节和施焊人数不同自动或手动调节控制箱梁内空气品质的功能。

A thermodynamic model of the inside space of box beams when welding is suggested and formulas for predicting emission control are presented A system for exhausting smoke and droping in temperature has been developed. The system possesses fuctions manually or automatically in adjusting and controling air quality of the inside space,acconding to variance in season and the welding staff.
