Description

Technical Field

[0001] The present application relates to the field of chemical production technology, and in particular to an anhydrous hydrogen fluoride dehydration device. Background Art

[0002] Anhydrous hydrogen fluoride is a chemical product with a wide range of uses. The content of hydrogen fluoride is above 99.8%. It is a colorless fuming liquid and is easily gasified under reduced pressure or high temperature. Anhydrous hydrogen fluoride has been widely used in atomic energy, chemical industry, petroleum and other industries. It is a strong oxidant and a basic raw material for the preparation of elemental fluorine, various fluorine refrigerants, inorganic fluorides, and various organic fluorides. It can be prepared into aqueous hydrofluoric acid for various purposes, used in the manufacture of graphite and catalysts for the manufacture of organic compounds, etc.

[0003] After searching, the patent document with announcement number CN217264850U discloses an anhydrous hydrogen fluoride dehydration device, which belongs to the field of chemical production technology. The key points of its technical solution are: it includes a dehydration box supported by multiple legs, and multiple air intake branches are arranged through the bottom of the dehydration box. The ends of the multiple air intake branches located outside the dehydration box are connected to the air intake main pipe. Each air intake branch located inside the dehydration box is provided with a sleeve at one end, and the sleeve is a cylindrical structure with a closed top and an open bottom. The inner top of the sleeve is connected to the top of the air intake branch, and the bottom end of the sleeve is close to the inner bottom surface of the dehydration box but does not touch each other. The side wall of the air intake branch is close to the top of the sleeve and has multiple air outlets arranged at the same height. The inner wall of the air intake branch is close to the top of the sleeve and has an anti-backflow part at one end, and the anti-backflow part is a conical structure with a small top and a large bottom and open at both ends. This anhydrous hydrogen fluoride dehydration device can prevent the backflow of anhydrous hydrogen fluoride during the dehydration process.

[0004] When the dehydrated anhydrous hydrogen fluoride is poured into the dewatering tank in the above device, the liquid level needs to be lower than the air outlet. Since the liquid level inside the water storage tank cannot be directly observed, the liquid is likely to enter the air inlet branch pipe, affecting the processing effect and having poor applicability.
