摘要:
The invention relates to an expandable media-retaining ring comprising an expandable ring and a gas permeable media-retaining membrane. The invention further relates to a gas purifier device comprising two or more beds of purification media and an expandable media-retaining ring. The expandable media-retaining ring is secured by radial force in the device, and prevents migration of purification media into adjacent beds, thereby improving the performance of the purifier device, and also enabling the device to be used in any orientation.
摘要(中):
本发明涉及一种包括可膨胀环和气体可渗透介质保持膜的可膨胀介质保持环。 本发明还涉及一种包括两个或多个净化介质床和可扩张介质保持环的气体净化装置。 可膨胀介质保持环通过设备中的径向力固定,并且防止净化介质迁移到相邻的床中,从而提高净化装置的性能,并且还使装置能够以任何方向使用。
