摘要

目的:研究检测车间运行过程中合理的气流组织和排风系统设施,解决车间内臭氧、氮氧化物等有害气体的积聚问题。方法:2023年5月,采用计算流体力学(CFD)技术对工业射线探伤作业产生的臭氧和氮氧化物的扩散进行数值模拟,并采用对比检测法对探伤车间通风系统改造前后的臭氧和氮氧化物浓度进行分析。结果显示通风系统改造后,检测车间臭氧平均浓度由 0.81 mg/m(3) 降至 0.03 mg/m(3),氮氧化物平均浓度由 0.42 mg/m(3) 降至 0.01 mg/m(3),差异有统计学意义(t=20.51,10.38,PC结论:检验车间通风设施采用上送下排的气流组织方式,通过通风水力平衡计算,科学设计通风管道,可有效控制检验车间有害气体浓度。

[Research on optimization technology of ventilation system in an industrial X-ray inspection workshop].

Objective: To investigate the reasonable airflow organization and exhaust system facilities during the operation of the inspection workshop, and solve the problem of the accumulation of harmful gases such as ozone and nitrogen oxides in the workshop. Methods: In May 2023, computational fluid dynamics (CFD) technology was used to numerically simulate the diffusion of ozone and nitrogen oxides generated by industrial radiographic inspection operations, and the comparative detection method was used to analyze the ozone and nitrogen oxides concentrations before and after the renovation of the ventilation system of the inspection workshop. Results: After the renovation of ventilation system, the average concentration of ozone in the inspection workshop decreased from 0.81 mg/m(3) to 0.03 mg/m(3), and the average concentration of nitrogen oxides decreased from 0.42 mg/m(3) to 0.01 mg/m(3), and the differences were statistically significant (t=20.51, 10.38, P<0.001) . Conclusion: The ventilation facilities of the inspection workshop are set up in the airflow organization mode of sending up and down the exhaust, and the ventilation pipes are scientifically designed through the calculation of ventilation hydraulic balance, which can effectively control the concentration of harmful gases in the inspection workshop.
