【摘要】：我国目前的尘肺病人数、接触粉尘人数、新增尘肺病人数均位于世界首位。而近年来机械加工的发展加快,越来越多的机械加工厂诞生,这其中以乡镇企业的增加量尤为突出。乡镇企业的工作人员大多缺乏自我保护意识且企业缺乏完善的通风除尘设备和防尘管理措施,导致尘肺病人数的进一步增加。为了保障作业人员的人身健康和经济的稳定发展,对机械加工厂的粉尘防治工作研究迫在眉睫。本文以某机械加工厂粉尘的综合防治为研究对象,从吹砂、喷涂、机加工、焊接打磨等几个方面的加工工艺出发。详细了解了各个工艺的工艺原理、产尘机理和产尘种类,并按照防尘八字方针“护、教、查、管、密、风、革、水”详细介绍了防尘技术,重点介绍了通风类型和除尘器种类的选择。并且通过对该厂的粉尘检测数据的分析和对该厂的现场调查,详细分析了该厂在防尘工作中的优点和缺点,并且针对该厂在机械加工工艺环节中防尘工作不足的地方提出改进建议。
[Abstract]:At present, the number of pneumoconiosis, dust exposure and new pneumoconiosis in China are in the first place in the world. But in recent years, the development of mechanical processing is accelerating, and more and more machinery processing plants are born. Most of the staff of township enterprises lack self-protection consciousness and enterprises lack of perfect ventilation and dust removal equipment and dust prevention management measures. It leads to the further increase of the number of pneumoconiosis. In order to ensure the personal health of the workers and the stable development of the economy. It is urgent to study the dust prevention and control in mechanical processing plant. This paper takes the comprehensive prevention and control of dust in a mechanical processing plant as the research object, from blowing sand, spraying, machining. Welding grinding and other aspects of the processing technology. Detailed understanding of the process principle, dust production mechanism and types of dust production, and according to the anti-dust eight-character policy "protect, teach, check, pipe, secret, wind, leather." The dust prevention technology is introduced in detail, with emphasis on the selection of ventilation type and dust precipitator type. Through the analysis of dust detection data and field investigation of the plant. The advantages and disadvantages of dustproof work in this factory are analyzed in detail, and suggestions for improvement are put forward in view of the shortage of dustproof work in the process of mechanical processing.
