An online adsorbent regeneration method for an SF6 purification treatment device includes the following steps:
cutting out a
nitrogen inlet pipeline, an SF6 inlet pipeline, a first pipeline, a secondpipeline, a third pipeline, a fourth pipeline, a fifth pipeline, a sixth pipeline and a seventh pipeline; connecting all the pipelines, a heating unit and an adsorption
tower as required; mounting valves, a pressure reducing valve, a filter and a
vacuum pump on the corresponding pipelines; and performing normal purification treatment, and discharging the obtained purified gas to the outside through a lye tank
tail gas outlet. When the adsorption capability of an adsorbent decreases or the
processing capacity is lost,
inert nitrogen goes through the adsorption
tower after being heated in orderto uniformly heat the adsorbent in the adsorption
tower, and then the adsorption tower is vacuumized to realize online depressurization and heating regeneration, so uniform distribution of the temperature in the cavity of the adsorption tower is ensured, a heating tube and the
sorbent is completely isolated, inadvertent operation of workers, untimely protection of a
temperature control system andother hidden dangers are avoided, the problem of airtightness of the device due to loading and unloading is completely solved, the regeneration cycle of the adsorbent is greatly improved, and the recycling of the adsorbent is realized.
