Method for transforming crude argon column condenser with non-condensable gas discharging pipe, and crude argon column condenser

A crude argon column and discharge pipe technology, applied in chemical instruments and methods, inert gas compounds, inorganic chemistry, etc., can solve the problem of increasing equipment materials and processing and manufacturing costs, increasing the processing difficulty of crude argon column condensers, and non-condensable gas emissions. Pipes are prone to leakage and other problems, so as to achieve the effect of reducing material cost, reducing labor cost and improving safety factor

Problems solved by technology

[0005] The existing crude argon tower condenser with a non-condensable gas discharge pipe has two disadvantages: one is that the processing difficulty of the crude argon tower condenser is increased due to the installation of the non-condensable gas discharge pipe, which improves the material and processing of the equipment. manufacturing cost
The second is that the non-condensable gas discharge pipe is very prone to leakage due to structural reasons, and once a leak occurs, even an extremely small leak will cause the failure of the entire air separation unit
[0007] It is precisely because the original crude argon column condenser with non-condensable gas discharge pipe has the disadvantages of difficult processing, high production cost and easy leakage, etc., we have been working hard to design a new type of crude argon column condenser, hoping that the new The condenser can avoid a series of disadvantages of the original condenser

Abstract

The invention relates to a method for transforming a crude argon column condenser with a non-condensable gas discharging pipe, and the crude argon column condenser. The method comprises the steps of: removing the non-condensable gas discharging pipe, and enclosing through holes at connecting parts of the gas discharging pipe, a lower end socket and a tank body; changing a liquid argon outlet pipe into a liquid argon outlet pipe with a caliber 1.3-2.0 times more than that of the former; and moving up the center line of the liquid argon outlet pipe to ensure that the center line is superposed with the center line of the lower end socket. The transformed crude argon column condenser has the advantages of easy processing, low cost and non-leakage.
