某氨基模塑粉生产企业粉尘危害治理及其效果

Effect evaluation of comprehensive dust control program in a urea-formaldehyde molding powder plant

  • 摘要: 目的 分析评价某氨基模塑粉生产企业粉尘危害治理设施及防护效果,为治理该行业粉尘危害提供依据。

    方法 针对企业现场粉尘浓度超标严重的情况以及原有除尘设施设计和安装等存在不符合相关技术标准和规范之处,进行治理和整改。通过前期现场调查、制定设计方案、更新防护设施和现场环境检测等措施,用时6个月实施该除尘设施综合治理项目。采用职业卫生现场调查和现场检测方法,检测治理前后作业场所粉尘的浓度和新的除尘系统罩口控制风速,比较治理前后作业场所粉尘的浓度。

    结果 治理前粉尘的防护设施不能满足除尘需求,多个检测点的总粉尘浓度超过职业卫生标准限值,定点检测结果的超限倍数的超标率为70%,最严重的超限倍数为限值的3.7倍;治理后各检测点的总粉尘浓度均符合卫生限值;新的除尘系统罩口控制风速能满足相关标准的除尘要求。

    结论 该企业采取的粉尘治理措施,效果显著,有一定的推广意义。

     

    Abstract: Objective To analyze and evaluate the protective effects of a comprehensive dust control program in a urea-formaldehyde molding powder plant, and provide scientific evidence for dust hazards control in the industry.

    Methods Excessive dust concentration in workplaces and unqualified dust removal equipment design or installation were subject to remediation. A six-month dust control program was conducted including preliminary field investigation, dust removal equipment design, protective equipment update, and on-site dust monitoring. Field investigation and on-site detection were carried out to compare the before-and-after workplace dust concentrations and test the hood capture velocities of new local exhaust ventilation facilities.

    Results Before the dust control program, the dust removal equipment were not effective, and excessive total dust concentrations were detected in multiple workstations; to be specific, the excess multiple of total dust concentrations in 70% selected wokstations exceeded occupational health standards, and the maximum was 3.7 times higher than the standard. After the control program, the total dust concentrations in all workplaces were qualified. The hood capture velocities of new local exhaust ventilation facilities was satisfactory for dust control.

    Conclusion The dust control program is proved to be effective in the urea-formaldehyde molding powder plant and deserves promotion.
