中央除尘设备是一种高效的空气净化系统，通过集中式设计实现对粉尘、颗粒物的收集与处理，广泛应用于工业生产、商业场所及大型公共设施，凭借其除尘效率高、运行稳定的特点，成为改善空气质量、保障作业环境的重要设备。

　　Central dust removal equipment is an efficient air purification system that collects and processes dust and particulate matter through centralized design. It is widely used in industrial production, commercial places, and large public facilities. With its high dust removal efficiency and stable operation, it has become an important equipment for improving air quality and ensuring the working environment.

　　从结构组成来看，中央除尘设备由多个核心部分协同工作。吸尘终端是直接接触粉尘的环节，包括安装在墙面或地面的吸尘口、柔性吸尘软管及各种吸尘配件，能适应不同场景的吸尘需求。管道系统作为粉尘输送的通道，多采用镀锌钢管或 PVC 管，管道布局遵循 “短路径、少弯头” 原则，减少气流阻力，确保粉尘顺利输送。主机系统是设备的核心，包含风机、滤尘装置及集尘箱，风机产生的负压将粉尘从终端吸入，经管道输送至主机，过滤后的洁净空气排出，粉尘则收集在集尘箱中。

　　From the perspective of structural composition, the central dust removal equipment consists of multiple core components working together. The vacuum terminal is the link that directly comes into contact with dust, including vacuum ports installed on walls or floors, flexible vacuum hoses, and various vacuum accessories, which can adapt to the vacuum needs of different scenarios. As a channel for dust transportation, pipeline systems often use galvanized steel pipes or PVC pipes. The pipeline layout follows the principle of "short path, few bends" to reduce airflow resistance and ensure smooth transportation of dust. The host system is the core of the equipment, including fans, dust filtering devices, and dust collection boxes. The negative pressure generated by the fans sucks in dust from the terminals, transports it to the host through pipelines, and the filtered clean air is discharged. The dust is collected in the dust collection box.

　　工作原理基于负压吸附与过滤分离。启动设备后，主机风机运转产生负压，粉尘在气压差作用下被吸入吸尘口，随气流沿管道移动。进入主机后，较大颗粒因重力落入集尘箱，细小粉尘随气流进入滤尘装置，被滤料截留，净化后的空气经出风口排放。部分设备配备自动清灰系统，清除滤料表面附着的粉尘，避免滤料堵塞导致风压下降，确保设备持续稳定运行。

　　The working principle is based on negative pressure adsorption and filtration separation. After starting the device, the main fan generates negative pressure, and dust is sucked into the suction port under the pressure difference, moving along the pipeline with the airflow. After entering the host, larger particles fall into the dust collection box due to gravity, while small dust enters the dust filtration device with the airflow and is intercepted by the filter material. The purified air is discharged through the air outlet. Some equipment is equipped with an automatic dust cleaning system to remove dust attached to the surface of the filter material, avoiding filter material blockage and reducing air pressure, ensuring the continuous and stable operation of the equipment.

　　适用场景覆盖工业与商业领域。工业方面，在机械加工车间，可针对产尘点设置专用吸尘罩，收集金属粉尘，防止操作人员吸入导致尘肺病；家具厂的切割、打磨工序，通过中央除尘收集木屑，既改善车间环境，又可将木屑回收作为燃料。商业与公共设施中，大型商场的中央空调系统可集成中央除尘，通过管道连接各楼层吸尘口，方便清洁人员快速清理地面灰尘；医院手术室采用低噪音中央除尘，收集手术过程中产生的粉尘、碎屑，避免交叉感染。此外，粮食加工企业利用中央除尘收集谷物粉尘，降低粉尘爆炸风险，符合安全生产规范。

　　Applicable scenarios cover both industrial and commercial sectors. In terms of industry, specialized dust collectors can be installed in mechanical processing workshops to collect metal dust and prevent operators from inhaling it, which can lead to pneumoconiosis; The cutting and polishing processes in furniture factories collect sawdust through central dust removal, which not only improves the workshop environment but also allows for the recycling of sawdust as fuel. In commercial and public facilities, the central air conditioning system of large shopping malls can be integrated with central dust removal, which is connected to the dust collection ports on each floor through pipelines, making it convenient for cleaning personnel to quickly clean the ground dust; The hospital operating room adopts low-noise central dust removal to collect dust and debris generated during the surgical process, avoiding cross infection. In addition, grain processing enterprises use central dust collectors to collect grain dust, reducing the risk of dust explosions and complying with safety production regulations.

　　相比传统除尘设备，中央除尘具有显著优势。除尘效率更高：传统单机吸尘器对粉尘的过滤效率较低，而中央除尘可达 99.9% 以上，尤其适合处理精细粉尘。操作更便捷：只需将吸尘软管插入就近的吸尘口，即可启动设备，无需频繁移动设备，降低劳动强度，清洁效率提升明显。维护成本更低：集尘箱容量大，无需频繁倾倒，滤料使用寿命长，且模块化设计便于部件更换。此外，中央除尘系统布局隐蔽，不占用地面空间，适合对车间布局要求高的企业。

　　Compared to traditional dust removal equipment, central dust removal has significant advantages. Higher dust removal efficiency: Traditional single machine vacuum cleaners have lower dust filtration efficiency, while central dust removal can reach over 99.9%, especially suitable for handling fine dust. More convenient operation: Simply insert the vacuum hose into the nearest vacuum port to start the device, without frequent movement, reducing labor intensity and significantly improving cleaning efficiency. Lower maintenance costs: The dust collection box has a large capacity, does not require frequent dumping, the filter material has a long service life, and the modular design facilitates component replacement. In addition, the layout of the central dust removal system is concealed and does not occupy ground space, making it suitable for enterprises with high requirements for workshop layout.

　　日常维护需注意以下要点。定期检查管道密封性，发现漏风及时修补；每周清理集尘箱，避免粉尘堆积过多影响气流；每月检查滤尘装置，破损滤料需立即更换，确保过滤效率不下降；每季度对风机进行保养，确保风压稳定。长期停用设备时，需清理管道与主机内的残留粉尘，关闭电源前运行 10 分钟，确保管道内无粉尘沉积，防止再次启动时粉尘飞扬。

　　Daily maintenance should pay attention to the following points. Regularly inspect the sealing of pipelines and promptly repair any air leaks found; Clean the dust collection box weekly to avoid excessive accumulation of dust that affects the airflow; Check the dust filtration device monthly and replace any damaged filter media immediately to ensure that the filtration efficiency does not decrease; Maintain the fan every quarter to ensure stable air pressure. When the equipment is stopped for a long time, it is necessary to clean the residual dust in the pipeline and the host. Before turning off the power, run for 10 minutes to ensure that there is no dust deposition in the pipeline and prevent dust from flying when restarted.
