Filter replacement process and apparatus |
摘要 |
The invention relates to a process and an apparatus for the replacement of a filter placed between the contaminated area and the uncontaminated area of a vessel. The filter is surrounded by a tightly sealed bag as from the uncontaminated area and this bag is sealingly fixed to the outer periphery of a supporting frame. The filter is removed from the supporting frame and placed on the bottom of the tightly sealed bag, which is welded at two spaced points. The bag is then cut between the two welds so as to obtain a tight diaphragm separating the two areas of the vessel. A supplementary supporting frame is then sealingly fixed to the supporting frame and a new filter is fitted from the uncontaminated area of the vessel. The tight diaphragm is then removed from the contaminated area.
