Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] The structure of the separation element with filtering and catalytic functions provided by the invention is as figure 1 As shown, it includes a filter screen 1 as a filter base, the filter screen 1 is coated with a metal catalyst layer 2, and a heating wire 3 is wound on the metal catalyst layer 2, and the metal catalyst layer is regulated by the heating wire 3. Catalytic temperature of layer 2.
[0017] The filter screen 1 of the present invention can be a metal screen, such as a stainless steel filter screen made by sintering, an iron-chromium-aluminum filter screen or a high-nickel steel filter screen; it can also be a non-metallic screen, such as a silicon-boron fiber screen .
[0018] When the filter screen 1 is a wire mesh, the metal catalyst layer 2 can be a copper catalyst layer, a nickel catalyst layer or a chromium catalyst...

The invention discloses a separating element with filtering and catalyzing functions. The separating element comprises a filtering silk screen serving as a filtering base body; the filtering silk screen is coated with a metal catalyzing layer. The separating element with filtering and catalyzing functions disclosed by the invention solves the problem that the production efficiency is influenced byshutting down for back flushing or offline cleaning after existing separating element is blocked. According to the separating element with filtering and catalyzing functions disclosed by the invention, the filtering silk screen is adopted as the filtering base body, the impurities filtered out are catalyzed for decomposition by the metal catalyzing layer on the filtering silk screen, and thus theloss caused by shutdown for treatment is avoided; meanwhile, the metal catalyzing layer is adjusted to work at a proper temperature by using a heating wire, thereby improving the catalyzing efficiency.
Description
technical field [0001] The invention belongs to the technical field of filtering devices, and in particular relates to a separation element with filtering and catalytic functions. Background technique [0002] At present, separation is already an important production link in the fields of environmental protection, coal chemical industry, petrochemical industry, food, etc., and the separated impurities are often trapped on the separation element, causing blockage to the separation element, although in recent years there have been various The same backflushing method, but all require the equipment to stop the backflushing to clean up impurities, or remove the filter element for off-line cleaning. Contents of the invention [0003] The purpose of the present invention is to provide a separation element with filtering and catalytic functions, which solves the problem that the existing separation element needs to be shut down for backflushing or off-line cleaning to affect prod...
