Automation krypton and xenon gas continuous bottle filling device

Abstract

The invention discloses an automation krypton and xenon gas continuous bottle filling device which comprises a storage device and a bottle filling device body and is characterized in that the bottle filling device body is composed of high pressure bottles arranged on left and right sides; the high pressure bottles are connected onto a cold box through a pipeline; an adjusting and control valve inrhombus arrangement is arranged on the pipeline and is connected with a PLC; a non-return valve and a stop valve are sequentially arranged at the bottom of the adjusting and control valve on the pipeline, the adjusting and control valve is finally connected with a gas filling pipeline at the bottom; a bottle filling valve and a safety valve are arranged on the gas filling pipeline; an air exhausting vacuum pump is arranged on one side; a vacuum valve is arranged between the vacuum pump and the pipeline; and a reducing valve is further arranged on the gas filling pipeline. The automation krypton and xenon gas continuous bottle filling device has the characteristics of continuously and alternately working, filling the bottle in an uninterrupted manner, improving the bottle filling efficiency, reducing the labor intensity and improving the operating safety.

Description

technical field [0001] The invention relates to gas bottle filling process equipment for an air separation unit, and belongs to the technical field of air separation units. Background technique [0002] The output of krypton-xenon rare gas is small, and the krypton-xenon gas produced from the splitter tower in the cold box has a small flow rate and low pressure, so it cannot be directly connected to the gas cylinder to fill the cylinder. The investment cost of small-scale liquefaction and vaporization equipment is high, and the equipment is large in size and high in energy consumption. Therefore, from the principle of bottle filling, the liquid nitrogen freezing method is adopted to liquefy the rare gas of krypton and xenon for storage. The raw material of liquid nitrogen is cheap and the effect is direct, so it is an ideal means of cooling. The krypton-xenon bottle filling device uses a high-pressure gas cylinder for storage, which is divided into two different stages of ...

AI Technical Summary

Problems solved by technology

Such repetitive work requires a large amount of manual work, and switching is performed at regular intervals, and the manual lifting mechanism is not safe and reliable. The weight of the liquid nitrogen tank is not small, and the positioning is not accurate when it is moved up and down. The liquid nitrogen tank needs to be adjusted every time it is switched position so that the aluminum bottle can be inserted into the liquid nitrogen tank and soaked in place

Therefore, the efficiency of filling the bottle is not high, and it is very error-prone, and there are potential safety hazards
