通风管道安装之后在运行之余还要进行清洗和维护，我们在挑选风管的时候，是不是便于清洗和维护也是风管选择的指标之一。妥善的维护可以保证风管的正常运行，可以增加风管的使用寿命。清洗工作可以减少风管内侧的灰尘和细菌保证室内的空气的洁净，一般情况下每年都要清洗一遍。随着工业化城镇化的不断推动，各行业厂房通风管道，承受的粉尘污垢压力不断增加，给通风管的清洗作业增加了压力。那么，通风管应该怎样清洗呢？对设备进行检修，清洗风管以及进出风口，检查通风管道的衔接是否可靠;阀门是否渗漏等。分段清洗通风管道，清洗风机及进出风口。
After the installation of the ventilation duct, it is necessary to clean and maintain it in addition to operation. When selecting the air duct, whether it is easy to clean and maintain is also one of the indicators for selecting the air duct. Proper maintenance can ensure the normal operation of the air duct and increase its service life. Cleaning work can reduce dust and bacteria on the inside of the air duct to ensure the cleanliness of the indoor air. Generally, it should be cleaned once a year. With the continuous promotion of industrialization and urbanization, the pressure of dust and dirt on ventilation ducts in various industries' factory buildings continues to increase, adding pressure to the cleaning operation of ventilation ducts. So, how should ventilation pipes be cleaned? Conduct maintenance on the equipment, clean the air ducts and air inlet and outlet, and check whether the connection of the ventilation ducts is reliable; Whether the valve is leaking, etc. Clean the ventilation ducts in sections, clean the fans and air inlet and outlet.
在风管的清洗过程中，严禁操作人员进入风管内部进行作业，应采用专业的清洗设备，将管道内部可视污染物有效的输送到指定的装置中。厂房通风管道排除有焚烧和爆破风险粉尘的空气，在进入排风机前应进行净化。
During the cleaning process of the air duct, it is strictly prohibited for operators to enter the interior of the duct for work. Professional cleaning equipment should be used to effectively transport visible pollutants inside the duct to the designated device. The ventilation duct of the factory building should remove air with incineration and explosion risk dust, and it should be purified before entering the exhaust fan.
对于空气中含有容易爆破的铝、镁等粉尘，应选用不产生火花的除尘器;如粉尘与水触摸能形成爆破性混合物，不该选用湿式除尘器。有爆破风险粉尘的排风机、除尘器，宜分组安置，并应与其他一般风机除尘器分开设置。当水平风道高度在2m以州苗木  保定电动门 保定空压机 化粪池模具 微型蠕动泵 保定强夯 收费岛模具上时，安装人员应系安全带。
For dust such as aluminum and magnesium that are prone to explosion in the air, non sparking dust collectors should be selected; If dust and water can form explosive mixtures by touching, wet dust collectors should not be used. Exhaust fans and dust collectors with blasting risk dust should be arranged in groups and separated from other general fan dust collectors. When the height of the horizontal air duct is above 2 meters, the installation personnel should wear safety belts.
