Abstract
The invention discloses a separation element with filtering and catalyzing functions, which comprises a filtering wire mesh used as a filtering substrate, wherein a metal catalyst layer is coated on the filtering wire mesh. The separating element with the filtering and catalyzing functions solves the problem that the production efficiency is influenced by stopping, back flushing or off-line cleaning after the existing separating element is blocked. The separation element with the filtering and catalyzing functions takes the filtering screen mesh as the filtering base body, and then decomposes the impurities catalytically filtered by the metal catalyst layer on the filtering screen mesh, so that the loss caused by shutdown treatment is avoided, and meanwhile, the metal catalyst layer is regulated to work at a proper temperature by the heating wire, so that the catalyzing efficiency is improved.
