Abstract

The invention discloses an automatic gas cylinder drying control device. The automatic gas cylinder drying control device comprises an electronic controller, a gas cylinder drying box and a gas pipeline, wherein the gas cylinder drying box is connected with the gas pipeline; and a control end in the gas pipeline is connected with the electronic controller. Compared with the prior art, the automatic gas cylinder drying control device has the advantages that repeated replacement evacuation of high-purity gas and water vapor is controlled by an automatic control system, the purpose of dewatering gas cylinders in the gas cylinder drying box is achieved effectively, the water vapor evacuation time is greatly shortened, and the drying efficiency of a gas cylinder drying device is improved.

Description

technical field [0001] The invention relates to an automatic control device, in particular to an automatic control device for drying gas cylinders which replaces and evacuates water vapor in the gas cylinders. Background technique [0002] In the prior art, commonly used gas cylinder drying devices usually use a temperature control system to externally heat the gas cylinder, and at the same time use an evacuation system to evacuate the internal water vapor of the heated gas cylinder, thereby achieving the purpose of dehydrating the gas cylinder. [0003] However, since the evacuation efficiency of water vapor in the gas cylinder is inversely proportional to the degree of vacuum, in order to make the water content in the gas cylinder meet the requirements of high-purity gas or even ultra-pure gas filling, the gas cylinder drying device often needs to work continuously for a long time. Drying efficiency is low. [0004] Therefore, an automatic control device for drying gas cy...
