Description

TECHNICAL FIELD

[0002] A glass production line often needs compressed air to perform a blowing and cooling process on glass and drive an extension cylinder and other actuators. The blowing and cooling process on glass has a high requirement for the dryness of compressed air, so the compressed air needs to be dried before being used as a process gas for blowing and cooling. Otherwise, the glass is prone to breakage, and a pattern that is difficult to remove is also prone to being formed on the glass, which affects the quality and yield of the glass.

[0003] The existing compressed air drying device has a high water content in the interior after being used for a period of time, so that the obtained compressed air is difficult to meet the process requirements. Therefore, the air drying device needs to be dehumidified so as to meet the drying requirements again.

[0070] When it is detected that the humidity of the compressed air dried by the gaseous desiccant in the first desiccant container 31 does not meet the process requirement, the compressed air outlet of the air compression assembly is controlled to be disconnected with the first air inlet passage 311 of the first desiccant container 31 and connected with the second air inlet passage 321 of the second desiccant container 32, so that the compressed air is stored in the air storage tank 7 after being dried by the gaseous desiccant in the second desiccant container 32. Further, the air outlet of the heat dissipation fan 2 is controlled to be connected with the first air inlet passage 511 of the first container 51, and the first air outlet 313 of the first desiccant container 31 is controlled to be opened, so that the outer wall of the first desiccant container 31 is heated by the heat generated by the air compression assembly to discharge the moisture in the first desiccant container 31, and then the gaseous desiccant in the first desiccant container 31 is restored to meet the drying requirement.

[0071] Similarly, when it is detected that the humidity of the compressed air dried by the gaseous desiccant in the second desiccant container does not meet the process requirement, the compressed air outlet of the air compression assembly is controlled to be disconnected with the second air inlet passage 321 of the second desiccant container 32 and connected with the first air inlet passage 311 of the first desiccant container 31, so that the compressed air is stored in the air storage tank 7 after being dried by the gaseous desiccant in the first desiccant container 31.
