作为干燥设备供应商，建议大多数干燥设备中的氧气含量应保持尽可能低。在理想情况下，任何干燥设备中的氧气含量应小于12％。如果在操作过程中氧气含量超过该值，建议您使用以下方法：

As a supplier of drying equipment, it is recommended that the oxygen content in most drying equipment should be kept as low as possible. Ideally, the oxygen content in any drying equipment should be less than 12%. If the oxygen content exceeds this value during operation, it is recommended that you use the following methods:

请将废气循环利用。这将增加蒸气和惰性气体的百分比，因此氧气百分比将减少。寻找并修-复空气泄漏的干燥设备。培训操作员和维护人员以密封所有敞开的入口，以使滚筒在密封的环境下保持工作。密封表面应光滑、圆润。一定要记住，如果圆度变小，则不可能使密封面充分旋转。

Please recycle the waste gas. This will increase the percentage of vapor and inert gas, so the percentage of oxygen will decrease. Find and repair - the drying equipment with air leakage. Train operators and maintenance personnel to seal all open entrances to keep the drum working in a sealed environment. The sealing surface shall be smooth and round. It must be remembered that if the roundness becomes smaller, it is impossible to fully rotate the sealing surface.

当干燥设备旋转时，如果其结构不完整，它将像水球在街上滚动一样，变得越来越大。因此，需要建立必要的标准。

When the drying equipment rotates, if its structure is incomplete, it will become larger and larger like a water ball rolling in the street. Therefore, the necessary standards need to be established.
