Beschreibung
Zusammenfassung:	The invention discloses a hydrogen chloride purification method and device, relates to the technical field of gas purification, and discloses a hydrogen chloride purification method which comprises the following steps: absorbing phosphorus pentafluoride doped in hydrogen chloride gas by using a phosphorus pentafluoride absorbent so as to obtain high-purity hydrogen chloride gas, so that the hydrogen chloride gas is convenient to recycle, and resources are saved. And the phosphorus pentafluoride absorbent which can be reduced after absorbing phosphorus pentafluoride to obtain high-purity phosphorus pentafluoride is selected, so that the phosphorus pentafluoride is convenient to recycle, and resources are saved. Besides, the porous lithium fluoride carbon framework filter element particles serving as the phosphorus pentafluoride absorbent are formed by adopting a linear styrene-butadiene block organic copolymer as a structural carrier of porous lithium fluoride powder, building a three-dimensional structure fix
