Document Type and Number:
WIPO Patent Application WO/2010/097233
Kind Code:
A3
Abstract:
A liquid ring vacuum pump (1) for degassing plastic melts, having a pump inlet (2) where gases are taken in, and a pump outlet (3) via which gases are blown out, and having a cycle (4) for the compression liquid, wherein a replaceable filter insert is provided for filtering coarse contaminants out of the compression liquid, and wherein a precondensation system is optionally provided upstream of the pump inlet for filtering fine contaminants out of the compression liquid, is to be further developed such that the pump is able to proceed continuous operation even during a filter change and that the compression liquid cycle does not have to be interrupted, wherein permanent stable process conditions are to be established, and wherein the management of the filter system is to be designed in a simple and energy-efficient and environmentally sound manner. The invention thus proposes for the compression liquid cycle (4) to be constantly closed and to have only one continuously operating fine and/or micro filter (5), replacing both the replaceable filter insert and the precondensation system.
