Abstract

The invention relates to a krypton-xenon tower heating device and a technology for heating a krypton-xenon tower using same, the invention is used for independently heating the krypton-xenon tower on the premise of continuous working when the krypton is extracted from the liquid oxygen. A krypton-xenon tower C6 is externally provided with a krypton-xenon tower cooling box, a heating passageway line is arranged on a first pipeline, a cutting-off valve V1 is arranged on the heating passageway line, a blow through pipeline and a blow through valve V10 are arranged on a fourth pipeline, a backflow circuit heating passageway line is arranged on a fifth pipeline, a plurality of switch valves V2, V3, V4 and V5 are respectively arranged on the fifth pipeline, a seventh pipeline, an eighth pipeline and a sixth pipeline, and two hand valves V6 and V7 are respectively arranged on a third pipeline and a ninth pipeline. When the technology is used for heating the krypton-xenon tower, a whole set of device is simple and convenient to operate and normal to transport the product without parking. The product air quantity is slightly reduced when only the krypton-xenon tower works, the uninterrupted follow-up gas usage is guaranteed, the production of a user is furthest guaranteed, and the energy consumption is saved.

Description

technical field [0001] The invention relates to a process and a device for extracting krypton and xenon from rare gases, in particular to a krypton-xenon tower heating system that can separately heat the krypton-xenon tower without stopping the vehicle when extracting krypton and xenon from liquid oxygen A device and a process for heating a krypton-xenon tower by using the device. Background technique [0002] Krypton and xenon are important industrial gases in the national economy. At present, the demand for krypton and xenon in my country and the world continues to maintain high growth, mainly because their application fields are becoming wider and wider. They are not only used in the traditional lighting industry, especially in building doors and windows, flat-screen TVs, electronics Applications in the chip, space, satellite and medical industries are also on the rise. [0003] Industrial production of krypton and xenon has the following ways: extraction from by-product...
