在打叶复烤车间里，烟叶经过多道工序的处理，释放出大量粉尘，让车间仿佛笼罩在迷雾之中，严重影响能见度，不仅威胁着工人的身体健康，还存在一定的安全隐患。想要打破这层 “迷雾”，需要一套全方位、多层次的高效除尘方案，从源头控制到末端治理，多管齐下重塑清朗的作业环境。

　　In the tobacco roasting workshop, after multiple processes, a large amount of dust is released from the tobacco leaves, making the workshop seem shrouded in mist, seriously affecting visibility. This not only threatens the physical health of workers, but also poses certain safety hazards. To break through this "fog", a comprehensive and multi-level efficient dust removal plan is needed, from source control to end treatment, to reshape a clear working environment through multiple measures.

　　首先，从生产工艺环节入手，减少粉尘的产生是关键的第一步。在烟叶的预处理阶段，通过优化烟叶的加湿工艺，让烟叶保持合适的含水率。当烟叶湿度适宜时，在后续的打叶、风分等工序中，破碎产生的粉尘量会明显降低。比如，精确控制加湿器的喷水量和喷雾均匀度，使烟叶在进入打叶机前达到理想的柔软度，降低烟叶碎裂成细小粉尘的概率。此外，对打叶机的刀片进行改良，采用更锋利、更耐磨且设计更科学的刀片，让烟叶在切割过程中受力更均匀，减少因切割不顺畅而产生的额外粉尘。同时，合理调整风分设备的风速和风量，既能保证有效分离烟叶和杂质，又避免因风速过大将烟叶过度吹碎产生大量粉尘。

　　Firstly, starting from the production process, reducing the generation of dust is the key first step. In the pre-treatment stage of tobacco leaves, by optimizing the humidification process of tobacco leaves, the appropriate moisture content of tobacco leaves can be maintained. When the humidity of tobacco leaves is suitable, the amount of dust generated by crushing will be significantly reduced in subsequent processes such as leaf cutting and air conditioning. For example, precisely control the amount of water sprayed by the humidifier and the uniformity of spray, so that the tobacco leaves can reach the ideal softness before entering the thresher, and reduce the probability of tobacco leaves breaking into fine dust. In addition, the blades of the tobacco cutting machine have been improved by using sharper, more wear-resistant, and scientifically designed blades, which make the force on the tobacco leaves more uniform during the cutting process and reduce the additional dust generated due to poor cutting. At the same time, adjusting the wind speed and volume of the air separation equipment reasonably can ensure effective separation of tobacco leaves and impurities, while avoiding excessive crushing of tobacco leaves due to excessive wind speed, resulting in a large amount of dust.

　　安装高效的除尘设备是直接解决粉尘弥漫问题的核心手段。在车间内合理布局吸尘罩，将其安装在粉尘产生的源头位置，如打叶机、风分机、筛分机等设备的出料口和进料口。吸尘罩的设计要符合空气动力学原理，确保能够最大限度地捕捉粉尘。通过管道将吸尘罩与大型的集中式除尘器相连，常见的布袋除尘器就十分有效，它利用纤维织物的过滤作用，当含尘气体通过滤袋时，粉尘颗粒被阻留在滤袋表面，清洁空气则通过滤袋排出。定期对布袋进行清理和更换，防止因布袋堵塞影响除尘效果。另外，也可搭配使用旋风除尘器，先通过旋风除尘器去除较大颗粒的粉尘，减轻后续布袋除尘器的负担，提高整体除尘效率。两种设备相互配合，能够有效降低车间内的粉尘浓度。

　　Installing efficient dust removal equipment is the core means to directly solve the problem of dust dispersion. Reasonably arrange the vacuum hood in the workshop and install it at the source of dust generation, such as the discharge and feed ports of equipment such as leaf blowers, fans, and screening machines. The design of the vacuum hood should comply with aerodynamic principles to ensure maximum capture of dust. By connecting the vacuum hood to a large centralized dust collector through a pipeline, the common bag filter is very effective. It utilizes the filtering effect of fiber fabric. When the dusty gas passes through the filter bag, the dust particles are trapped on the surface of the filter bag, and the clean air is discharged through the filter bag. Regularly clean and replace the bag to prevent dust removal from being affected by bag blockage. In addition, a cyclone dust collector can also be used in combination to remove larger particles of dust first, reducing the burden on subsequent bag filters and improving overall dust removal efficiency. The combination of two devices can effectively reduce the dust concentration in the workshop.

　　加强车间的通风换气系统，能进一步改善粉尘弥漫的状况。设计合理的通风管道和排风口，确保车间内的空气能够形成良好的流动循环。采用机械通风与自然通风相结合的方式，在车间顶部安装排风扇，及时排出积聚在车间上方的粉尘；在车间墙壁上设置可开启的窗户，在天气条件允许时，打开窗户进行自然通风，引入新鲜空气。同时，对进风口进行过滤处理，防止室外的灰尘进入车间，保证进入车间的空气洁净。通过良好的通风换气，不仅能降低车间内粉尘的浓度，还能改善车间的空气质量，为工人创造更舒适的工作环境。

　　Strengthening the ventilation system in the workshop can further improve the situation of dust dispersion. Design reasonable ventilation ducts and exhaust outlets to ensure good air circulation in the workshop. Adopting a combination of mechanical ventilation and natural ventilation, installing exhaust fans at the top of the workshop to promptly remove dust accumulated above the workshop; Install openable windows on the workshop walls, and when weather conditions permit, open the windows for natural ventilation to introduce fresh air. At the same time, filter the air inlet to prevent outdoor dust from entering the workshop and ensure clean air entering the workshop. Through good ventilation, not only can the concentration of dust in the workshop be reduced, but the air quality in the workshop can also be improved, creating a more comfortable working environment for workers.

　　建立完善的清洁管理制度和工人防护措施也必不可少。制定严格的日常清洁计划，安排专人定期对车间地面、设备表面、墙壁等进行清扫，使用吸尘器或湿布擦拭，避免采用扬尘较大的清扫方式。定期对车间的除尘设备进行维护保养，检查管道是否有破损、漏风，除尘器的运行是否正常等，确保除尘设备始终处于高效运行状态。为工人配备专业的防尘口罩、防护眼镜、工作服等个人防护用品，并加强对工人的培训，让他们了解粉尘的危害和正确的防护方法，提高自我保护意识。

　　Establishing a comprehensive cleaning management system and worker protection measures are also essential. Develop a strict daily cleaning plan, assign dedicated personnel to regularly clean the workshop floor, equipment surfaces, walls, etc., using a vacuum cleaner or damp cloth to wipe, and avoid using cleaning methods with high dust. Regularly maintain and upkeep the dust removal equipment in the workshop, check for any damage or air leakage in the pipelines, and ensure the normal operation of the dust collector to ensure that the dust removal equipment is always in efficient operation. Equip workers with professional dust masks, protective goggles, work clothes and other personal protective equipment, and strengthen training for workers to understand the hazards of dust and correct protection methods, and improve self-protection awareness.
